Somatic symptoms without a clear-cut organic or biomedical background, also called "medically unexplained" or "somatoform" symptoms, are frequent in primary and secondary health care. They are often accompanied by depression and/or anxiety, and cause functional impairment. The Patient Health Question-naire Somatic Symptom Scale (PHQ-15) was developed to measure somatic symptom distress based on the frequency and bothersomeness of non-specific somatic symptoms. The study aimed to (1) evaluate the Hungarian version of the PHQ-15 from a psychometric point of view; (2) replicate the bifactor structure and associations with negative affect described in the literature; and (3) provide the Hungarian clinical and scientific community with reference (normal) values split by sex and age groups.PHQ-15, depression (BDI-R), and subjective well-being (WHO-5) scores obtained from a large (n = 5020) and close to representative community sample (Hun-garostudy 2006) were subjected to correlation analysis and linear structural equation modeling.The PHQ-15 showed good internal consistency (Cronbach's α = 0.810; McDonald's ω = 0.819) and moderate to strong correlation with the BDI-R (rs = .49, p0.001) and WHO-5 (rs = -.48, p0.001). Fit of the bifactor structure was excellent; in independent analyses, the general factor was strongly associated with depression (β = 0.656±0.017, p0.001) and well-being (β = -0.575±0.015, p0.001), whereas the symptom specific factors were only weakly or not related to these constructs. The PHQ-15 score was higher in females and showed a weak positive association with age. The Hungarian PHQ-15 is a psychometrically sound scale which is positively associated with depression and ne-gatively related to subjective well-being. The bifactor structure indicates the existence and meaningfulness of a gene-ral factor representing the affective-motivational component of somatic symptom distress.The Hungarian version of the PHQ-15 is a brief and usable tool for the pre-screening of somatization disorder (DSM-IV) or somatic symptom disorder (DSM-5). The reported reference values can be used in the future for both clinical and research purposes.Az organikus háttérrel nem rendelkező (szomatoform) tünetek gyakoriak az elsődleges és másodlagos betegellátásban. Gyakran társulnak depresszióval és/vagy szorongással, és jelentős funkcionális korlátozott­sá­got okoznak, így mérésük mindenképpen indokolt. A Beteg Egészségi Állapot Kérdőív Testi Tünet Skálát (Patient Health Questionnaire Somatic Symptom Scale; PHQ-15) a testi tünet distressz mérésére fejlesztették ki. A vizsgálat célja a PHQ-15 magyar változatának pszicho­metriai vizsgálata és a negatív affektivitással való kapcsolat replikációja, valamint a normálpopulációra vonatkozó nem és életkor szerinti referenciaértékek közlése. Felté­te­leztük azt, hogy az adatok jó illeszkedést mutatnak a bi­fak­toros modellel, valamint azt, hogy a negatív affektivitás indikátorai, ezen belül is elsősorban a közös faktorra sú­lyoznak.Kérdőíves keresztmetszeti vizsgálat.

Background: mindfulness meditation is effective at fostering the executive functioning of children, i.e., the skills that play important roles in academic performance and social–emotional wellbeing. One possible mechanism for such an effect might be that meditation practices can decrease stress, especially if someone is at a risk for elevated cortisol levels, for instance, due to a stressful life event, such as starting school. Participants and methods: the present pilot study tested the effects of a six-session mindfulness intervention applied right after school entry compared to a passive control group. In total 61 first graders participated (Mage = 84.95 months, SD = 5.21) in this study from four classes of a primary school in Budapest. Repeated-measures ANOVA were performed to explore the effects on executive functioning skills and cortisol levels. Results: no effect was found on morning salivary cortisol levels, but the working memory capacities of girls significantly improved as a result of the intervention. Conclusions: a relatively short, story-based mindfulness intervention can improve the working memory capacities of first-graders; thus, it could potentially contribute to the academic performance and adaptation of children in schools.

Beneficial physical and physiological health outcomes of yoga practice are well-supported by empirical data. However, whether weekly frequency of training is sufficient to evoke positive changes, is still an open question. The present intervention study investigated the effects of 10 weekly sessions of beginner level hatha yoga with respect to indicators of physical fitness and physiological markers. 82 young women (mean age of 22.0 ± 3.83 years) participated in the study. The yoga group (N = 49) attended a yoga course consisting of 10 sessions (1.5 h each) on a weekly basis. The control group (N = 33) did not receive any intervention. BMI, body fat percentage, balance (one-leg-stand test with open and closed eyes, functional reach test), flexibility (side bend test, modified sit and reach test) core muscle strength (plank test) as well as resting heart rate (HR), and heart rate variability (HRV) were assessed 1 week before and after the course. Both frequentist and Bayesian analysis showed an improvement in flexibility and balance in the yoga group compared to the control group. The yoga group showed also increased core muscle strength. No changes with respect to BMI, body fat percentage, resting HR and HRV were found. Ninety minute beginner level hatha yoga classes were characterized by 93.39 HR and 195 kcal energy consumption on average. The present findings suggest that weekly setting of a 10-session long hatha yoga training leads to improvements in balance, flexibility and core muscle strength among healthy young women. However, for changes in BMI, body fat percentage, resting HR and HRV longer, and/or more intense interventions are needed.

Our aim was to conceptually replicate the findings of previous empirical studies showing that people with higher cardiac interoceptive accuracy experience more intense emotions. Apart of the mental heartbeat tracking task of Schandry, Hungarian (n = 46, 76.0% female, mean age 22.28 ± 2.228) and Norwegian (n = 50, 60.0% female, mean age 24.66 ± 3.048) participants rated the arousal and valence evoked by positive, neutral and negative pictures. Multivariate repeated analysis of variance (applying both frequentist and Bayesian approaches) did not reveal any connection between heartbeat perception scores and the subjective ratings (i.e., arousal and valence) of the pictures in any of the two groups. The lack of the expected association between cardioceptive accuracy and arousal might partly be explained by the methodological differences between previous studies and this one; for example, we did not split or preselected the sample based on the performance on the Schandry task and applied a relatively strict instruction (i.e., by encouraging to count felt heartbeats only, and to report zero if no sensations were detected).

Paranoid ideation is assumed to characterize worries about possible harmful effects of modern technologies (MHWs) and idiopathic environmental intolerances (IEIs), such as IEI attributed to electromagnetic fields (IEI-EMF). Empirical evidence on these associations is scarce.In a cross-sectional on-line survey, participants of a community sample (n = 700; mean age: 28.4 ± 12.0; 434 females) completed the Somatosensory Amplification Scale, the Modern Health Worries Scale, and the Paranoid Ideation scale of the Symptom Checklist 90 Revised. They were considered IEI-EMF if (1) they categorized themselves so, (2) they had experienced symptoms that they attributed to the exposure to electromagnetic fields, and (3) the condition impacted their everyday functioning.Paranoid ideation was significantly positively associated with MHWs (standardized β = 0.150, p .001) even after controlling for socio-demographic variables and somatosensory amplification tendency, an indicator of somatic symptom distress. Also, paranoid ideation explained significant variability in IEI-EMF (OR = 1.090, 95% CI: 1.006-1.180, p = .035) even after statistically controlling for socio-demographic variables and somatosensory amplification.Paranoid ideation was found to be associated with MHWs and IEI-EMF. This association appears independent of general somatic symptom distress in both cases. This might partly explain the temporal stability of these constructs.

Although association between sustained attention and various aspects of interoception (i.e. the perception of the body state) seems plausible, research on this subject is scarce. In the present study, 74 undergraduate students (41 females; age: 22.3 ± 4.04 yrs) filled out the Body Awareness Questionnaire, the Mindful Attention Awareness Scale, and the Somatosensory Amplification Scale and completed the Heartbeat Counting Task (HCT), a sensory-perceptual measure of cardiac interoception and the PEBL Continuous Performance Test (CPT) assessing sustained attention. The HCT score showed a weak to moderate negative correlation with the number of commission errors shown in CPT, indicating a lack of response inhibition (frequentist analysis: rs = −0.313, p = 0.008; Bayesian analysis: τb = −0.216, BF10 = 5.865). Questionnaire measures did not show any connection with CPT-performance. These findings suggest that the subjective representation of attentiveness to bodily processes is unrelated to the objectively measured sustained attention. Response inhibition, however, is moderately related to HCT performance.

Essential oils of herbal origin are widely used in the treatment of diseases of the upper and lower respiratory tract primarily due to their antibacterial and antiviral effects. Menthol, the major component of the essential oil of mint (Mentha) species, exhibits antispasmodic activity, which might result in improved lung function. In a randomized experiment, 106 healthy participants received nebulized peppermint, eucalyptus, or rosemary essential oil for 15 min or no treatment (control). None of the essential oils had an impact on the measured spirometric variables (forced vital capacity, peak expiratory flow, the ratio of the volume of air forcibly blown out in the first second to forced vital capacity). Participants' expectations regarding the effects of essential oils did not affect their objective performance, however, they predicted perceived (subjective) changes. Perceived and measured changes were not connected with each other. In conclusion, inhaled rosemary, peppermint, and eucalyptus essential oils' subjective (perceived) effect on spirometry is mediated at least partly by expectations.

Expectations shape human behavior. Initial drug use might be associated with information-based expectations. In this study, we presumed that changes in affect and perceived physical wellbeing will be stronger after receiving an active placebo (Tic Tac mint; n = 40), than a pure placebo (inert pill; n = 40) given as a mood-enhancing "super pill." After baseline measures, participants completed a treatment-expectancy scale, ingested the mint/super pill, and attended to the effects over 3-minutes. Subsequently, they completed again the psychological tests. Expectancy scores were positive and did not differ between the groups. The pure placebo group increased in physical wellbeing but less than the active placebo group, which also showed an increase in positive affect. Negative affect decreased in both groups. The Tic Tac produced greater affective changes than the pure placebo. Since these are new findings on the ultra-short placebo effects on affect, the results might have relevance for drug-use studies.

Empirical evidence supporting the effectiveness of pulsed (electro)magnetic field (PEMF) therapy on chronic and acute pain is equivocal. In the current randomized, double-blind, placebo-controlled experiment, impact of a commercially available whole-body PEMF mat on acute ischemic muscle pain induced in the forearm was studied with the participation of 70 healthy volunteers. The device emitted a pulsed magnetic field with a repetition frequency of 2.05 Hz and a maximum flux density of 25.3 μT (rms). The highest dB/dt was 48 mT/s. No differences between the groups receiving actual and sham PEMF were found in terms of pain threshold, pain tolerance, heart rate, and perceived decrease of pain. However, participants' expectation concerning the effectiveness of the intervention improved pain tolerance and affected perceived change of pain. In conclusion, the used PEMF device had no specific effect on acute ischemic muscle pain, while the contribution of the placebo effect was considerable.

Various aspects of interoception are regarded as temporally stable phenomena. This study investigates the temporal stability of and longitudinal associations between interoceptive accuracy (as measured with heartbeat tracking task) and a related concept, body awareness (assessed by self-report).In a two-month longitudinal study 103 university students (31% male, 23.34±4.34yrs.; 44 Hungarians; 36.4% male, 21.4±1.67yrs. and 59 Norwegians; 25.4% male, 24.8±5.09yrs) were investigated using Schandry's heartbeat tracking task and the Body Awareness Questionnaire.Both interoceptive accuracy and body awareness showed good test-retest reliability (r=0.60 and r=0.73, respectively; p0.001 in both cases). The two concepts were independent of each other at baseline (r=0.06, p=0.587), and did not predict each other over an eight weeks period of time.Self-reported body awareness and objectively measured interoceptive accuracy are temporally stable and not related to each other.

This study investigated the temporal stability and correlates of attention-related body sensations that emerge without external stimulation during rest and due to focused attention on a body part.To assess attention-related body sensations, participants were asked to focus on a freely chosen body area with closed eyes, and had to report whether the sensation of that area had changed. Self-report questionnaires were used to assess various aspects of body focus (body awareness, body responsiveness, somatosensory amplification, subjective somatic symptoms), and positive and negative affectivity. Previous experiences in body-mind therapies were also measured. PEBL Continuous Performance Test was used to assess sustained attention. Heart rate variability scores were based on a 3-minute long resting heart rate measurement.Fifty-eight university students (22.3 ± 3.95 years; 34 females) participated in the study. The stability of attention-related body sensations was measured 8 weeks later on a randomly chosen sub-group (n = 28).Attention-related body sensations showed a mediocre temporal stability (rAttention-related sensations are relatively stable over time. They are connected to some, but not to all of the aspects of body focus. Further studies are needed to elaborate the influencing stable and situational factors.

Although nature relatedness is considered a positive characteristic, its relationship to constructs involving worries about the negative effects of artificial environmental factors is also feasible. A questionnaire assessing modern health worries, electrosensitivity, somatosensory amplification, spirituality, and nature relatedness was completed by 510 individuals. Nature relatedness was related to electrosensitivity, modern health worries, and spirituality. In a binary logistic regression analysis, somatosensory amplification, modern health worries, and nature relatedness were associated with electrosensitivity, and nature relatedness moderated the connection between modern health worries and electrosensitivity. In naive representations, “natural” might be associated with health, whereas “modern” and “artificial” evoke negative associations.

Purpose Proprioception plays an essential role in motor control and in psychological functioning: it is the basis of body schema and the feeling of body ownership. There are individual differences in the processing accuracy of proprioceptive stimuli. Although proprioceptive acuity plays an important role in physical competence, there are contradictory findings concerning the role it plays in healthy psychological functioning. This study aims to shed more light on this association. Material and methods Sixty-eight young adults participated in this study. We estimated proprioceptive acuity by the reposition accuracy of elbow joint positions. We tested both dominant and non-dominant hands with two different versions of Joint Position Reproduction Test. Perceived physical competence, body awareness, and affectivity were assessed using questionnaires (Physical Competence scale of Body Consciousness Questionnaire, Somatic Absorption Scale, and Positive and Negative Affectivity Schedule, respectively). Results No significant association between proprioceptive acuity and body awareness, perceived body competence, and positive and negative affect was found. Conclusion Proprioceptive acuity, measured in the elbow joint, does not play a substantial role in body awareness, perceived body competence, and affect.

The rubber hand illusion (RHI) is a widely used tool in the study of multisensory integration. It develops as the interaction of temporally consistent visual and tactile input, which can overwrite proprioceptive information. Theoretically, the accuracy of proprioception may influence the proneness to the RHI but this has received little research attention to date. Concerning the role of cardioceptive information, the available empirical evidence is equivocal. The current study aimed to test the impact of proprioceptive and cardioceptive input on the RHI. 60 undergraduate students (32 females) completed sensory tasks assessing proprioceptive accuracy with respect to the angle of the elbow joint, a heartbeat tracking task assessing cardioceptive accuracy (the Schandry-task) and the RHI. We found that those with more consistent joint position judgements (i.e., less variable error) in the proprioceptive task were less prone to the illusion, particularly with respect to disembodiment ratings in the asynchronous condition. Systematic error, indicating a systematic distortion in position judgements influenced the illusion in the synchronous condition. Participants with more proprioceptive bias toward the direction of the rubber hand in the proprioceptive test reported a stronger felt embodiment. The results are in accordance with Bayesian causal inference models of multisensory integration. Cardioceptive accuracy, however, was not associated with the strength of the illusion. We concluded that individual differences in proprioceptive processing impact the RHI, while cardioceptive accuracy is unrelated to it. Theoretical and practical relevance of the findings are discussed.

Under resting conditions, cardioceptive accuracy-the acuity of the perception of heartbeats-is associated with the self-reported intensity of affective states but not with reported valence. Physical exertion elicits positive affect below the anaerobic threshold and negative affect above the threshold while arousal gradually increases. The current research aimed to study the associations between cardioceptive accuracy and characteristics of the affective response (arousal and valence) during physical activity. About 67 undergraduate students completed the Schandry task and rated their perceived exertion (Borg-scale) and affective experience (arousal and valence) under three physical loads (running on a treadmill below, around, and above the anaerobic threshold). Cardioceptive accuracy was associated with the arousal component of the affective states during physical activity but not with valence and perceived exertion.

Previous research demonstrated that individuals are able to reliably reproduce their heart rate under physical load, however, they are prone to underestimate it. It was also assumed that the ability to perceive heartbeats under resting conditions might play a role in the regulation of physical activity. In an experimental setting, 47 young individuals were asked to complete the Schandry task and reproduce three different exercise intensities with respect to heart rate on a treadmill. Resting heartbeat counting was moderately related to replication performance under slight physical load, but not under more intense conditions. In all exercise conditions, participants were prone to underestimate their actual heart rate. No significant gender difference was revealed. Actual and perceived performance were moderately associated at rest, but not under physical load. In conclusion, perception of heartbeats at rest is related to replication of heart rate during physical activity only at very weak physical load.

The frequency of self-reported food sensitivity (SFS) is increasing, and has a negative impact on the well-being and everyday functioning of the affected people. A considerable proportion of SFS cannot be medically explained. The lack of knowledge of its origin and treatment causes further stress in those affected. Purpose - This study aims to get a better understanding of the psychological background of the condition.A non-representative community sample (N=335; age: 35.1±13.18 yrs; 75.8% female) completed an English on-line questionnaire assessing somatosensory amplification, health anxiety, modern health worries (MHWs), beliefs concerning the scientific validity of complementary and alternative medicine (CAM), holistic beliefs on health and illness.In multiple binary logistic regression analyses, SFS were associated with CAM related beliefs, somatosensory amplification, and health anxiety after controlling for age and gender. The connection between somatosensory amplification and SFS were completely mediated by health anxiety. No differences between the two groups were found with respect to MHWs, worries about the harmful effects of various artificial components in food, and holistic health beliefs. Discussion: More positive attitudes toward CAM might be based on the lack of conventional treatment, rather than on higher levels of MHWs or a more holistic worldview. Both the existence of symptoms and the presence of health anxiety might be needed for the development and maintenance of SFS.The findings support the notion that somatosensory amplification and health anxiety might play a role in the development and maintenance of SFS.A szubjektív (öndiagnózison alapuló) ételérzékenység prevalenciája folyamatosan nő, az állapot negatív hatással van az érintettek jóllétére és mindennapi működésére egyaránt. Az esetek jelentős része klinikailag nem diagnosztizálható, ami további stressz forrása. Kérdésfelvetés - A vizsgálat célja a szubjektív ételérzékenység pszichológiai hátterének jobb megismerése.Online kérdőíves vizsgálat. A vizsgálat alanyai - Egy nem reprezentatív közösségi minta tagjai (335 fő; életkor: 35,1±13,18 év; 75,8% nő) töltöttek ki egy angol nyelvű kérdőívcsomagot, ami a szomatoszenzoros amplifikációs tendenciát, az egészségszorongást, a modernkori egészségféltést, a természetgyógyászati módszerekkel kapcsolatos attitűdöt, valamint az egészséggel és betegséggel kapcsolatos holisztikus hiedelmeket mérte.Többszörös bináris logisztikus regressziós elemzésekben a szubjektív ételérzékenység a nem és az életkor kontrollját követően is kapcsolódott a természetgyógyászattal kapcsolatos pozitívabb attitűdökhöz, valamint a szomatoszenzoros amplifikáció és az egészségszorongás magasabb szintjéhez. A szomatoszenzoros amplifikáció és a szubjektív ételérzékenység közötti kapcsolatot az egészségszorongás teljes mértékben mediálta. Nem találtunk kapcsolatot ugyanakkor a modernkori egészségféltés, az ételekben található mesterséges anyagokkal kapcsolatos aggodalmak, valamint a holisztikus egészségszemlélet vonatkozásában.A természetgyógyászattal kapcsolatos pozitív attitűdök mögött elsősorban a konvencionális kezelés hiánya állhat. Az eredmények támogatják azt az elképzelést, miszerint mind a szomatoszenzoros amplifikáció, mind az egészségszorongás szerepet játszhat a szubjektív ételérzékenység kialakulásában és fennmaradásában.

The questionnaire study aimed to evaluate the relative contribution of body awareness, subjective symptoms, and anxiety to the construct of somatosensory amplification in both healthy controls ( n = 475) and patients visiting their general practitioner ( n = 236). Regression analysis explained 52.0 percent of total variance of the somatosensory amplification scale scores. Body awareness was the most influential predictor ( β = 0.489, p

Modern health worries (MHWs) refer to perceived risk to personal health from technological changes and features of modern life, and is associated with health outcomes. The present objective was to test the hypotheses of (i) associations between MHWs and a global measure of typical somatization symptoms, referred to as somatic symptom distress, and (ii) associations between MHWs and a broad range of specific typical somatization symptoms and eye/skin and airway symptoms.Cross-sectional population-based data were used. Validated instruments were used to assess MHWs (Modern Health Worries Scale), typical somatization symptoms (Patient Health Questionnaire 15-item Somatic Symptom Severity Scale, PHQ-15), eye/skin and airway symptoms (Environmental Hypersensitivity Symptom Inventory), depression and anxiety (Hospital Anxiety and Depression Scale). Multivariate linear regression analyses were conducted with MHWs as dependent variable, symptoms as independent variables, and background variables, anxiety and depression as confounding variables.When controlled for background variables, MHWs were statistically significantly, but only very weakly, associated with global PHQ-15 score, most of the specific typical somatization symptoms, and eye/skin and airway symptoms. When controlled also for depression and anxiety, the associations were statistically significant, but even more weakly associated with global PHQ-15 score and most of the specific symptoms.The results suggest a very small increased risk of somatic symptom distress and related specific symptoms in MHW, and that depression and anxiety are confounding variables in these associations.

Worries about possible harmful effects of new technologies (modern health worries) have intensely been investigated in the last decade. However, the comparability of translated self-report measures across countries is often problematic. This study aimed to overcome this problem by developing psychometrically sound brief versions of the widely used 25-item Modern Health Worries Scale (MHWS) suitable for multi-country use. Based on data of overall 5,176 individuals from four European countries (England, Germany, Hungary, Sweden), Ant Colony Optimization was used to identify the indicators that optimize model fit and measurement invariance across countries. Two scales were developed. A short (12-item) version of the MHWS that represents the four-factor structure of the original version and an ultra-short (4-item) scale that only measures the general construct. Both scales show that overall levels of health worries were highest in England and Hungary, but that the main reason for concern (e.g. electromagnetic radiation or food related fears) differs considerably between these countries. This study also shows that even if measurement invariance of translated self-report instruments across countries is problematic, it can be optimized by using adequate item selection procedures. Differences of modern health worries across countries and recommendations for cross-cultural research are discussed.

Objective Two studies were conducted to shed light on the associations between trait and state rumination and worry and a time-domain metric of heart rate variability, the root mean square of successive differences (RMSSD) of cardiac interbeat-interval (IBI). Method Study 1 involved 130 healthy adults (118 females; mean age = 23.4 ± 3.59 years), while 72 healthy participants (58 females; mean age = 22.2 ± 1.79 years) were involved in Study 2. RMSSD was calculated from a 5-min baseline recording and state ruminative thoughts were assessed during measurement. Trait perseverative cognitions were measured using self-reported questionnaires. Results In Study 1, we found that a higher level of state but not trait ruminative thoughts showed weak negative association with lnRMSSD. In Study 2, we replicated the results of Study 1 and we found that trait reflection moderated the relationship between state rumination and lnRMSSD. Conclusion State rumination may reflect actual cardiovascular activity better than trait preservative cognitions, although trait reflection could be a protective factor.

According to the proposition of several theoretical accounts, the perception of the bodily cues, interoceptive accuracy and interoceptive sensibility, has a significant positive impact on subjective well-being. Others assume a negative association; however, empirical evidence is scarce. In this study, 142 young adults completed questionnaires assessing subjective well-being, interoceptive sensibility, and subjective somatic symptoms and participated in measurements of proprioceptive accuracy (reproduction of the angle of the elbow joint), gastric sensitivity (water load test), and heartbeat tracking ability (Schandry task). Subjective well-being showed weak to medium positive associations with interoceptive sensibility and weak negative associations with symptom reports. No associations with measures of interoceptive accuracy were found. Gastric sensitivity as opposed to heartbeat perception and proprioceptive accuracy moderated the association between interoceptive sensibility and well-being. Thus, subjective well-being is associated only with the self-reported (perceived) aspect of interoception but not related to the sensory measures of interoceptive accuracy.

Body focus is often considered an undesirable characteristic from medical point of view as it amplifies symptoms and leads to higher levels of health anxiety. However, it is connected to mindfulness, well-being and the sense of self in psychotherapy. The current study aimed to investigate the contribution of various body focus related constructs to acute and chronic generation and maintenance of medically unexplained symptoms (MUS). Thirty-six individuals with idiopathic environmental intolerance to electromagnetic fields (IEI-EMF) and 36 controls were asked to complete questionnaires assessing negative affect, worries about harmful effects of EMFs, health anxiety (HA), body awareness, and somatosensory amplification (SSA), and to report experienced symptoms evoked by a sham magnetic field. Body awareness, HA, SSA, and EMF-related worries showed good discriminative power between individuals with IEI-EMF and controls. Considering all variables together, SSA was the best predictor of IEI-EMF. In the believed presence of a MF, people with IEI-EMF showed higher levels of anxiety and reported more symptoms than controls. In the IEI-EMF group, actual symptom reports were predicted by HA and state anxiety, while a reverse relationship between symptom reports and HA was found in the control group. Our findings show that SSA is a particularly important contributor to IEI-EMF, probably because it is the most comprehensive factor in its aetiology. IEI-EMF is associated with both a fear-related monitoring of bodily symptoms and a non-evaluative body focus. The identification of dispositional body focus may be relevant for the management of MUS.

Side effects consist of drug-specific and non-specific symptoms. Both components are based on bodily sensations that a person perceives after taking a drug and subsequently attributes to the drug. We suggest that somatosensory amplification (SSA) may explain a proportion of inter-individual differences in reports of side effects that cannot be accounted for by drug-specific safety profiles. This hypothesis was investigated in hypertensive patients starting a new pharmacotherapy. This longitudinal study included 50 patients (66 % women, aged 55 ± 14 years) with a diagnosis of primary hypertension. Patients completed the Somatosensory Amplification Scale (SSAS), started to take their new medication, and recorded side effects on a daily basis for 4 weeks. After controlling for age, gender, number of pills taken, and previous personal and family experiences with medication side effects in the regression analyses, SSAS scores remained a significant predictor of reported side effects over the entire study period (weeks 1 and 2: β = .621, p

Polar watches with heart rate monitoring function have become popular among recreational and professional athletes. In addition to monitoring functions, they calculate a specific index called OwnIndex which is claimed to measure aerobic training status. The current research attempted to shed light on the factors determining the OwnIndex. In Study 1, OwnIndex calculated by the RS-400 Polar watch was estimated using anthropometric (gender, age, height, weight), cardiovascular (resting HR, RMSSD), and exercise-related (maximal oxygen uptake, self-reported physical activity) data of 45 young adults. In Study 2, the OwnIndex was measured in 21 young adults twice, first with self-reported physical activity set to the lowest, then to the highest value. In the regression analysis (Study 1), the only significant predictor of OwnIndex was self-reported physical activity (R² = 0.883; β = 0.915, p < 0.001). A significant difference with a large effect size (t(20) = -16.657, p

The paper reviews and summarizes the history and the development of somatosensory amplification, a construct that plays a substantial role in symptom reports. Although the association with negative affect has been supported by empirical findings, another key elements of the original concept (i.e. body hypervigilance and the tendency of focusing on mild body sensations) have never been appropriately addressed. Recent findings indicate that somatosensory amplification is connected with phenomena that do not necessarily include symptoms (e.g. modern health worries, or expectations of symptoms and medication side effects), and also with the perception of external threats. In conclusion, somatosensory amplification appears to refer to the intensification of perceived external and internal threats to the integrity of the body ("somatic threat amplification") rather than amplification of perceived or actual bodily events only. Practical implications of this new approach are also discussed.

Relationships among interoceptive sensitivity (IS), body image dissatisfaction, body mass index (BMI), and self-reported body awareness were investigated in a cross-sectional study. Eighty-two Norwegian high school students and 70 Hungarian undergraduate university students participated in the study. Subjects completed two questionnaires (Body Image Ideals Questionnaire - BIQ; Body Awareness Questionnaire - BAQ) followed by the assessment of interoceptive sensitivity using the Mental Tracking Method (MTM). An inverse, medium-level relationship between body image dissatisfaction and IS was found in both the Norwegian and the Hungarian samples. The relationships between IS and self-reported body awareness, and between body image dissatisfaction and BMI were uniformly non-significant in both samples. Predictors of body image dissatisfaction were resting heart rate, gender, and IS in the regression analysis after controlling for BMI, age, and nationality. The negative relationship between IS and body image dissatisfaction described in patients with anorexia nervosa also exists in healthy individuals. There is no direct connection between IS and self-reported body awareness. Language: en

Electrodermal activity (EDA) provides the means to gauge the activity of the sympathetic nervous system. Assessment of EDA for research purposes requires measurement systems that are sensitive to small changes in arousal in the full measurement range, collecting, storing, and monitoring data. The objective behind designing a new open-source device was to be able to measure EDA simultaneously on many subjects, monitoring their activity in real time remotely and collecting high precision data suitable for analyses. To assure feasibility of simultaneous measurements on multiple subjects, the devices must be compact and wearable, without compromising data quality. Experiments were carried out using synchronized devices in group and single subject environments. Validity of EDA measurements of Obimon was demonstrated compared to a reference system (Nexus) during a breathing exercise, a short movie, and while exposed to loud computer-generated tones, using Pearson correlation, Passing-Bablok regression, and Bland-Altman analysis. Seamless management of several Obimons and real-time visualization of EDA via Android phone/tablet application from a large number of participants was demonstrated. Based on analyses of the data collected, we conclude that the Obimon device presented here is a valid and feasible tool for collecting EDA in single or multisubject environments.

In the development of somatosensory amplification, health anxiety, and modern health worries, environmental factors seem more important than genetic background. Parental attitudes might represent a major source of learning. In total, 186 adolescents and their parents completed a questionnaire assessing modern health worries, somatosensory amplification, health anxiety, and somatic symptoms. Adolescents’ modern health worries, somatosensory amplification, and health anxiety were positively related to respective parental characteristics in regression analyses even after controlling for sociodemographic variables and somatic symptoms. Parental beliefs may play a role in the development of these characteristics.

The cross-sectional study aimed at the psychometric evaluation of the Modern Health Worries Scale in adolescents and the exploration of the relationship among modern health worries, somatosensory amplification, health anxiety, and somatic symptoms. A total of 480 secondary school students (aged between 14 and 19 years) completed a set of questionnaires. Four-factor structure of the scale was confirmed by confirmatory factor analysis. Modern health worries were connected to somatosensory amplification and health anxiety, and somatosensory amplification and health anxiety were partial mediators of the connection between modern health worries and somatic symptoms. Perceived vulnerability (conceptualized as somatosensory amplification and health anxiety) appears to build a “social-cognitive-emotional bridge” between symptoms and modern health worries.

The study aimed to assess the attitudes of laypeople toward clinical placebo use. One of three imaginary stories was presented randomly in a popular news portal and participants (6,404 individuals) were asked to rate nine statements about it. In the stories, placebo therapy was used in a deceptive way. Following the success of the treatment, the patient was informed that the remedy contained no active substances. Along with self-report of attitudes, questionnaires measuring dispositional optimism, somatosensory amplification and beliefs about the scientific validity of complementary and alternative medicine and holistic health were also completed. According to participants' ratings, helping patients is more important than avoiding deception. They did not think that they would have felt deceived in the described situation or that treatment would have been successful in a fully informed case. Patients' attitude toward deceptive placebo use appears to be more pragmatic than has been previously supposed.

Introduction ‘Idiophatic Environmental Intolerance attributed to electromagnetic fields’ (IEI-EMF) refers to the perception of subjective symptoms during or following EMF exposure. IEI-EMF has become disproved to be a mostly biologic entity by now, and evidences accumulate to support the role of nocebo effect in the phenomenon. The two aims of this study were to demonstrate the significant role of the nocebo effect in physical symptoms reported at 50 Hz frequency of EMF exposure, as well as to explore some psychological factors which may predispose to IEI-EMF. Methods A total of 40 volunteer university students have completed a battery of psychological questionnaires (expectations; IEI-EMF; state anxiety – STAI-S; dispositional optimism – LOT-R; somatisation – PHQ-15; somatosensory amplification – SSAS) before, and checklists of physical symptoms during sham exposure to “weak” and “strong” EMFs, respectively. Participants were also asked about the extent to which they had perceived the presence of the presumed EMF. Results Participants with higher IEI-EMF scores expected and experienced more symptoms. Suggestion of stronger EMF exposure resulted in larger symptom scores and enhanced EMF-perception as compared to the presumed weaker exposure. Experienced symptom scores were predicted primarily by somatisation scores, whereas self-rating of IEI-EMF was predicted by somatosensory amplification scores. Conclusion The results confirm that there is considerable nocebo effect in symptom reports related to 50 Hz frequency EMFs. IEI-EMF seems to be formed through a vicious circle of psychosocial factors, such as enhanced perception of risk and expectations, self-monitoring, somatisation and somatosensory amplification, causalization and misattribution.

Pilates exercises have several demonstrated physical and psychological benefits. To date, most research in this context was conducted with symptomatic or elderly people with few dependent measures. The current study examined the chronic or longitudinal effects of very low frequency, once a week, Pilates training on several physical and psychological measures, over a 10-week intervention, in young, healthy, and sedentary women. Further, the study gauged the acute effects of Pilates exercises on positive- and negative affect in 10 exercise sessions. Compared to a control group, the Pilates group exhibited significant improvements in skeletal muscle mass, flexibility, balance, core- and abdominal muscle strength, body awareness, and negative affect. This group also showed favorable changes in positive (22.5% increase) and negative affect (12.2% decrease) in nine out of ten exercise sessions. This work clearly demonstrates the acute and chronic benefits of Pilates training on both physical and psychological measures. It also reveals that even only once a week Pilates training is enough to trigger detectable benefits in young sedentary women. While this frequency is below the required levels of exercise for health, it may overcome the 'lack of time' excuse for not exercising and subsequently its tangible benefits may positively influence one's engagement in more physical activity.

Modern health worries (MHWs) are widespread in modern societies. MHWs were connected to both negative and positive psychological characteristics in previous studies. The study aimed to investigate the relationships among intuitive-experiential information processing style, spirituality, MHWs, and psychological well-being. Members of the Hungarian Skeptic Society (N = 128), individuals committed to astrology (N = 601), and people from a non-representative community sample (N = 554) completed questionnaires assessing intuitive-experiential information processing style, spirituality, modern health worries (MHWs), and psychological well-being. Astrologers showed higher levels of spirituality, intuitive-experiential thinking, and modern health worries than individuals from the community sample; and skeptics scored even lower than the latter group with respect to all three constructs. Within the community sample, medium level connections between measures of spirituality and the experiential thinking style, and weak to medium level correlations between spirituality and MHWs were found. The connection between MHWs and experiential thinking style was completely mediated by spirituality. Individuals with higher levels of spirituality are particularly vulnerable to overgeneralized messages on health related risks. Official communication of potential risks based on rational scientific reasoning is not appropriate to persuade them as it has no impact on the intuitive-experiential system.

A large body of research has been accumulated concerning the relationship between circadian preferences (chronotype) and certain personality traits and psychopathological symptoms. Given that chronotype is related to clinically relevant personality traits, risk factors as well as diurnal variations in behavioural performance, the reliable measurement of circadian preferences might become an important step in daily psychiatric practice. In the present study, we examined the psychometric properties of the Hungarian adaptation of the Morningness- Eveningness Questionnaire (MEQ-H).Based on the (online) questionnaire data of 840 healthy individuals, we examined the factor structure and the internal reliability of the questionnaire. The validity was assessed by different scales (sensory seeking, depressive symptoms and sleep complaints) that were previously shown to be associated with chronotype. Test-retest reliability was calculated from the data of 55 participants who completed the questionnaire twice (eight months apart).We identified two strongly correlated but separate factors, that we called Morning freshness and Circadian rhythm. According to our results, the questionnaire is a reliable instrument in order to measure individual differences in these factors, however, to increase the reliability of the scale as well as in light of practical considerations, the use of a shortened 13-itemed version might be reasonable. The two factors of the MEQ-H showed the expected associations with the examined constructs, however, the independent predictors of Morning freshness were age, gender, depressive symptoms and sleep complaints (insomniac symptoms and morning misalignment), while the independent predictors of Circadian rhythm were age, gender, depressive symptoms, circadian misalignment and sensory seeking.The MEQ-H fulfils the methodological requirements of reliability and validity testing, and proved to be an adequate instrument in order to measure circadian preferences: an important factor that could be included in experimental or clinical investigations.

Negative non-specific (nocebo-like) effects of medications and electromagnetic fields are often described as results of mistaken attribution. The current study aimed to find empirical evidence supporting this theory. Participants completed questionnaires assessing modern health worries, health anxiety, and somatosensory amplification, were assigned to one of three conditions (placebo pill with sedative information, sham magnetic field, or control), and completed a 14-min vigilance task. Changes in physiological arousal (heart rate, heart rate variability, and skin conductance) and reported symptoms were also measured. Finally, causal attributions concerning cognitive performance and reported symptoms were assessed. No increase in symptom reports and physiological arousal was measured in the two intervention groups. A perceived negative effect on cognitive performance was attributed to both sham conditions, and attributions were connected to modern health worries. A proportion of reported symptoms was ascribed to the placebo pill but not to the sham magnetic field. Symptom attributions were not related to any assessed psychological variables. An aroused physiological state is not necessary for the automatic causal attribution process. Negative effects attributed to medication and environmental factors can be regarded as unavoidable side effects of human cognitive-emotional functioning; they might be alleviated, but cannot be completely eradicated.

In spite of the apparently bidirectional relationship between daytime emotions and nocturnal sleep quality, relatively few studies have examined the day-to-day co-variation of daytime emotional states and sleep quality. In order to address this issue, we used a 7-day prospective design allowing for the simultaneous investigation of the bidirectional link between sleep quality and affective states. Seventy-five healthy university students completed a daily log during 7 days, reporting subjective sleep quality after their final morning awakenings. Eight hours later, they completed the Positive and Negative Affect Schedule measuring daytime affective states. Multilevel modeling was applied in order to examine level 1 (day-to-day co-variation of sleep quality and affective states within individuals) as well as level 2 (averaged between-subjects) effects. Individuals reporting poor sleep quality (on average) were characterized by lower positive and higher negative affect during daytime. Similarly, higher positive and lower negative affect (on average) predicted better subjective sleep quality during the assessment period. Moreover, daily ratings of positive and negative affect were related to the subjective sleep quality of the preceding night: On occasions in which participants reported poor (below average) sleep quality, they also reported lower positive and higher negative affect during the day. Nevertheless, daytime positive and negative affective states did not predict subsequent sleep quality ratings. These findings suggest daily dynamic associations between subjective sleep quality and next day’s emotional states in a group of healthy individuals, while in the inverse, the co-variation between daytime affective states and subsequent sleep quality was not supported.

Impact of 5 mg/kg caffeine, chance of receiving caffeine (stimulus expectancies), and expectations of effects of caffeine (response expectancies) on objective (heart rate (HR), systolic/diastolic blood pressure (SBP/DBP), measures of heart rate variability (HRV), and reaction time (RT)) and subjective variables were investigated in a double-blind, placebo-controlled experiment with a no-treatment group. Participants were 107 undergraduate university students (mean age 22.3 ± 3.96 years). Consumption of 5 mg/kg caffeine had an impact on participants' SBP, standard deviation of normal heartbeat intervals, HR (decrease), and subjective experience 40 minutes later even after controlling for respective baseline values, stimulus and response expectancies, and habitual caffeine consumption. No effects on DBP, high frequency component of HRV, the ratio of low- and high-frequency, and RT were found. Beyond actual caffeine intake, response expectancy score was also a determinant of subjective experience which refers to a placebo component in the total effect. Actual autonomic (SBP, HR) changes and somatosensory amplification tendency, however, had no significant impact on subjective experience. Placebo reaction plays a role in the subjective changes caused by caffeine consumption but it has no impact on objective variables. Conditional vs deceptive administration of caffeine (i.e. stimulus expectancies) had no impact on any assessed variable.

While an increasing number of research is devoted to the understanding of placebo effects in sports, athletes' experiences with and attitudes towards the use of placebo for performance enhancement remain poorly understood. In this study, 79 elite athletes from different sports were surveyed on five issues related to placebo use in sports. Results showed that 47% of the athletes have experienced placebo effects in the past. A majority of the athletes (82%) thought that placebos could affect their sports performances. A wider use of placebos in sport settings was endorsed more by those who have experienced placebo effects in the past than those who did not (P = .005). Regardless of past experience with placebo, more than half of the athletes (53%) would accept an unknown but legitimate substance from the coach, and 67% of them would not mind a placebo-linked deception if that was effective. These findings confirm that most elite athletes believe in the power of placebos in enhancing sports performance, and those having a positive past experience exhibit slightly more favourable attitudes in contrast to those without such experiences.

Effects of inhaled essential oils (EOs) cannot be explained by pharmacological mechanisms alone. The study aimed to investigate the effects of pleasantness of and expectancies evoked by EOs. A double-blind experiment with a within-subject design was carried out with the participation of 33 volunteering adults (15.2% male; mean age 37.7 ± 10.90 years). Participants were exposed to three EOs (rosemary, lavender, and eucalyptus) for three minutes in a quasi-random order, expectations were simply assessed prior to exposure. Subjective (perceived) changes in alertness, heart rate (HR), and blood pressure (BP), and objective changes in HR, BP, and indices of heart rate variability were recorded. Significant group-level differences in changes in alertness and no differences for the cardiovascular variables were found. Participants’ expectations predicted changes in alertness in the case of rosemary and lavender oils but had no impact on cardiovascular variables. EOs’ pleasantness had no effect on any assessed variable. Perceived changes in BP and HR were not related to the respective objective changes but were connected to perceived changes in alertness. Expectancies play an important role in the subjective effects of inhaled EOs. Perceived subjective changes are used to estimate changes in non-conscious (e.g., visceral) states.

A great body of research indicates that eveningness is associated with negative psychological outcomes, including depressive and anxiety symptoms, behavioral dyscontrol and different health impairing behaviors. Impaired subjective sleep quality, increased circadian misalignment and daytime sleepiness were also reported in evening-type individuals in comparison with morning-types. Although sleep problems were consistently reported to be associated with poor psychological functioning, the effects of sleep disruption on the relationship between eveningness preference and negative emotionality have scarcely been investigated. Here, based on questionnaire data of 756 individuals (25.5% males, age range = 18-43 years, mean = 25.3 ± 5.8 years), as well as of the evening-type (N = 211) and morning-type (N = 189) subgroups, we examined the relationship among sleep problems, eveningness and negative emotionality. Subjects completed the Hungarian Version of the Horne and Östberg Morningness-Eveningness Questionnaire (MEQ-14), The Athen Insomnia Scale (AIS) and the Epworth Sleepiness Scale (ESS). Moreover, a composite score of Negative Emotionality (NE) was computed based on the scores of the Short Beck Depression Inventory (BDI-9), the Perceived Stress Scale (PSS-4) and the General Health Questionnaire (GHQ-12). Morning and evening circadian misalignment was calculated based on the difference between preferred and real wake- and bedtimes. Two possible models were tested, hypothesizing that sleep problems (circadian misalignment, insomniac symptoms and daytime sleepiness) moderate or mediate the association between eveningness and negative emotionality. Eveningness preference was correlated with increased NE and increased AIS, ESS and circadian misalignment scores. Our results indicate that eveningness-preference is an independent risk factor for higher negative emotionality regardless of the effects of age, gender, circadian misalignment and sleep complaints. Nevertheless, while chronotype explained ∼6%, sleep problems (AIS and ESS) accounted for a much larger proportion (∼28%) of the variance of NE. We did not find a significant effect of interaction (moderation) between chronotype and sleep problems. In contrast, insomniac symptoms (AIS) emerged as a partial mediator between chronotype and NE. These findings argue against the assumption that indicators of mental health problems in evening-type individuals can be explained exclusively on the basis of disturbed sleep. Nevertheless, negative psychological outcomes seem to be partially attributable to increased severity of insomniac complaints in evening-types.

Modern health worries (MHWs) were related to somatic symptoms and to preference of holistic healing methods in previous studies.The study aimed to investigate the contribution of symptom-related and holism-related factors to MHWs.Participants (visitors of an Internet news portal; N = 16152; 64.1 % males) completed a questionnaire assessing MHWs, somatosensory amplification, somatic symptoms, positive and negative affect, spirituality, holistic health beliefs, and various aspects of health care utilization (both conventional and alternative).Exploratory factor analysis with oblique rotation revealed two independent dimensions ("Somatic symptom distress" and "Holism") MHWs were involved with factor loadings of 0.294 and 0.417, respectively. The existence of two factors was supported by the results of confirmatory factor analysis. No practically significant interaction between the two factors was found in binary logistic regression analysis. Positive and negative affect, somatosensory amplification, spirituality, and holistic health beliefs were positively connected, while self-rated health status was negatively connected to MHWs even after controlling for socio-demographic and treatment-related variables.Holistic thinking and symptom-related behavioral and psychological factors are independently associated with MHWs. Modern health worries can be conceptualized as symptom-related by-products of a holistic-spiritual worldview.

The aim of this work was to examine the link between the physical-perceptual characteristics of nutritional supplements and their expected effectiveness in enhancing sport performance. Participants (n = 267) ranked nine images of fictive nutritional supplements, varying in shape, color, and route of administration (e.g., pill, powder, lotion, etc.), in ranked- order of expected effectiveness. They performed the task three times, 1) for strength, 2) endurance, and 3) for concentration. Results have revealed that the perceived effectiveness of the supplements was statistically significantly different for the three types of performances (p < .001). A significant interpersonal variability was observed in the ranking-order of the supplements. The findings reveal that perceptual characteristics of ‘believed to be nutritional supplements’, aimed at sport performance enhancement, influence their perceived effectiveness. Future inquiries in sport nutrition should examine the relationship between expected and experienced effectiveness of various nutritional supplements in enhancing sport performance.

Introduction The tendency of experiencing unpleasant symptoms in the proximity of working electric devices is called idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF). Evidence about psychophysiological backgrounds of the phenomenon (i.e., detection ability and mechanisms of symptom generation) is not yet conclusive. Methods Participants of the provocation experiment were 29 individuals with self-reported IEI-EMF and 42 control persons. Participants completed questionnaires (symptom expectations, somatosensory amplification – SSAS, modern health worries radiation subscale – MHW-R), and attempted to detect the presence of 50 Hz 0.5 mT magnetic field (MF) directed to their right arm in 20 subsequent 1-min sessions. Heart rate was also recorded and various indices of heart rate variability (HF, LF/HF, SDNN) were calculated. Results Using the methodology of the signal detection theory, individuals with IEI-EMF as opposed to the control group showed a higher than random detection performance (d′ differed slightly but statistically significantly from zero), and they used a significantly lower criterion (β value) when deciding about the presence of the MF. Detection sessions followed by correct decisions (hits or correct rejections) were characterized by higher HRV (SDNN and HF indices) than periods followed by errors (misses or false alarms). Previous expectations and affiliation to the IEI-EMF group were significant predictors of symptoms reported following exposure. IEI-EMF was closely related to MHW-R and SSAS scores. Conclusion Detection of MF might be possible for people with IEI-EMF to some extent. Although heightened sensibility to MFs may play a role in the development and/or in the perpetuance of the IEI-EMF phenomenon, symptoms attributed to the MF seem to be mainly of psychogenic origin.

Relationship among modern health worries (MHWs), somatosensory amplification (SSA), and attributional styles was investigated in a cross-sectional questionnaire study. A total of 99 university students, 104 patients visiting their General Practitioners, and 102 future alternative therapists completed questionnaires assessing MHWs, SSA, negative affect (NA), and psychological, somatic and normalizing (environmental) attribution styles. Significant correlation between SSA and MHWs was found in all three samples. MHWs and psychological attribution style were significantly associated with Complementary and Alternative Medicine (CAM)-orientation in the regression equation even after controlling for SSA, NA, and sociodemographic variables. MHWs were independent from any attribution styles in the student and patient samples, while significant correlations with all three styles were found in the CAM group. Previously described association between MHWs and SSA was replicated in three different samples. The connection between MHWs and CAM preference seems to be independent from SSA, NA or any particular attribution style.

The aim of the study was to examine the relationship of mindfulness to the emotional quality of dreaming. In our questionnaire-based study, comprising the data of 587 undergraduate students we examined the association between trait anxiety, perceived stress, trait mindfulness, negative dream affect and dream anxiety. Our results indicate that mindfulness is inversely related to disturbed dreaming and predicts less severe dream disturbances after controlling for trait anxiety. Moreover, the results of the applied hierarchical regression analysis suggest that mindfulness is associated with reduced dream anxiety by moderating the extent of waking anxiety. Our findings extend previous research relating mindfulness, emotional regulation and sleep quality to the domain of dream research. We suggest that mindfulness is a possible protective factor against dream disturbances.

The theoretically hypothesized connection between modern health worries (MHWs) and somatosensory amplification (SSA), as well as the factor structure of the Hungarian version of the MHW scale were investigated in a cross-sectional questionnaire study. A total of 163 university students (mean age = 21.3± 2.70 yrs; 44.2% male) and 145 patients (mean age = 49.4±17.51 yrs; 31.7% male) visiting their general practitioners (GPs) completed questionnaires assessing MHWs, SSA, subjective somatic symptoms (PHQ-15), and trait anxiety (STAI-T). The previously described four-factor structure of the MHW scale was confirmed using confirmatory factor analysis (CFA). In the linear regression analysis, participants' age and SSA scores were positively related to MHWs even after controlling for gender, anxiety, and subjective somatic symptom scores. The conclusions are that: MHWs are indicators of cognitive, behavioral and social level of sensitization for health-related concerns; SSA can provide the somatic background process for generation and/or misattribution of subjective somatic symptoms; better understanding of the cognitive-emotional background of MHWs could help to determine possible interventions.
