The Flourishing Scale (FS) is one of the most well-known tools for assessing psychological flourishing. However, its psychometric properties have been little analyzed in the case of teachers. This study aimed to examine the validity of the scale in the case of a sample of Romanian teachers and to analyze the latter's level of flourishing. In this regard, 323 Romanian teachers from the pre-university education system were recruited. Confirmatory factor analysis (CFA) was used to assess the construct validity of the scale, and Cronbach's α and McDonald's ω indices were used to assess internal consistency. The convergent validity was assessed by associating the FS with other instruments related to well-being: the Mental Health Continuum-Short Form and the Scale of Positive and Negative Experience. Network analysis was performed to examine the items that are particularly influential in the scale. As a result of the CFA, the one-factor structure of the scale was certified (χ2/df = 1.39; CFI = 0.99; RMSEA = 0.035). The internal consistency is excellent (both α and ω = 0.89). The FS correlates with both of the scales which operationalize components of well-being. The teachers' flourishing level is above average. The network approach showed that the items related to self-acceptance, optimism, and respect had the highest indicators of centrality, and the item related to supportive social relationships was the least informative in the network. For the male subsample, flourishing means optimism about the future and respect for others, and for the female respondents, it is related to self-acceptance and respect. The results provide support for using the scale in assessing flourishing among teachers. [ABSTRACT FROM AUTHOR]

Adequate surgical margins are essential in oral cancer treatment, this is, however, difficult to appreciate during training. With advances in training aids, we propose a silicone-based surgical simulator to improve training proficiency for the ablation of oral cavity cancers. A silicone-based tongue cancer model constructed via a 3D mold was compared to a porcine tongue model used as a training model. Participants of varying surgical experience were then asked to resect the tumors with clear margins, and thereafter asked to fill out a questionnaire to evaluate the face and content validity of the models as a training tool. Eleven participants from the Otolaryngology-Head and Neck Surgery unit were included in this pilot study. In comparison to the porcine model, the silicone model attained a higher face (4 vs. 3.6) and content validity (4.4 vs. 4.1). Tumor consistency was far superior in the silicone model compared to the porcine model (4.1 vs. 2.8, p = 0.0042). Fellows and staff demonstrated a better margin clearance compared to residents (median 3.5 mm vs. 1.0 mm), and unlike the resident group, there was no incidence of positive margins. The surgical simulation was overall useful for trainees to appreciate the nature of margin clearance in oral cavity cancer ablation. [ABSTRACT FROM AUTHOR]

The Illness Management and Recovery Scale (IMR-S) is based on the IMR program, developed to assess the recovery process for people with severe mental disorders by considering the perceptions of clients and clinicians involved in it. The aim of this study was to analyze the psychometric properties of the IMR-S so as to determine the reliability and suitability of its scores for evaluating recovery. Two coders searched five databases for studies, published between January 2004 and May 2023, that describe the psychometric assessment of the IMR-S. Studies were assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. Finally, 46 papers were included. Methodological quality was very good for most of the studies that provide information on internal validity, and limited for those that report on responsiveness. Measurement properties were positive for convergent validity and measurement error. The quality of evidence was high for structural validity studies. Although this study only includes research published in English and may have overlooked certain psychometric properties evaluated in studies published in other languages, our findings suggest that the IMR-S is a valid and reliable instrument, demonstrating its potential to offer guidance for clinical practice.

The present study proves the construct validity of the German versions of the Feeling Scale (FS) and the Felt Arousal Scale (FAS) for measuring the affective responses (affective valence and arousal) for a moderate-intensity jogging (JG) exercise. In previous studies, both scales were validated for a high-intensity bicycle ergometer exercise and for relaxation techniques. In the present study, 194 participants performed the JG exercise for 45 min and completed the FS and the FAS, as well as the Self-Assessment Manikin (SAM), for a self–other comparison in a pre-test-intervention-post-test design. The results of the correlation analyses replicated the previous findings for the high-intensity bicycle ergometer exercise and the relaxation techniques, revealing significant positive correlations for the valence dimension between the FS and the SAM-Pleasure subscale (r = 0.50) and for the arousal dimension between the FAS and the SAM-Arousal subscale (r = 0.16). These findings suggest that the German versions of the FS and the FAS are also suitable for exercises of moderate intensity. [ABSTRACT FROM AUTHOR]

Basic psychological need crafting assumes that need-based experiences are enhanced through intentional behavior and thought changes. Despite its known benefits outside of the work context, need crafting instruments designed for this context, and the implications of need crafting for employee functioning, remain underexplored. Thus, this study set out to adapt and validate the need crafting scale (NCS) among employees (n = 229). Results supported the construct, discriminant validity, and criterion validity of the NCS. The research also revealed that, through need crafting, employees reported enhanced experiences related to their needs, which led to higher work effort and engagement and a reduced desire to leave their jobs. Additionally, the different types of need crafting had differential direct effects on employee functioning, supporting a more nuanced understanding of the construct. As the first of its kind, the study underpins the relevance and generalizability of the NCS and need crafting in the workplace. [ABSTRACT FROM AUTHOR]

The finger tapping test (FTT) is a tool to evaluate the motor performance of the hand and fingers and eye-hand coordination with applicability in people with multiple sclerosis (pwMS). The aim of this study was to evaluate the intra- and inter-rater reliability of the TappingPro® mobile app and the construct validity between this app and validated clinical scales for motor performance in healthy subjects and pwMS. 42 healthy subjects (mean age 25.05) and 13 pwMS (mean age 51.69, EDSS between 3 and 7.5E) participated. FTT was performed with the TappingPro® mobile app. All participants were examined twice, with a one-week interval between the two appointments. For the analysis of construct validity, the Jamar® hydraulic hand dynamometer, Box and Blocks Test (BBT), and Nine Hole Peg Test (NHPT) were used. The intra-rater reliability showed a good correlation (Intraclass Correlation Coefficient, ICC > 0.787) for both upper limbs and both times of FTT for healthy subjects, and an excellent correlation (ICC > 0.956) for upper limbs and both times of FTT for pwMS. The ICC for the inter-rater reliability was good (ICC = 0.869) for the non-dominant upper limb in the FTT 10 s of the healthy subjects, and excellent (ICC > 0.904) for all the other measurements of the healthy subjects and pwMS. However, the Bland–Altman plots showed disagreement between observers and measurements that should be considered in the interpretation of clinical evaluations. The correlation analysis for healthy subjects showed poor associations between all variables, except for the association between hand grip strength and the FTT 60 s in the non-dominant upper limb, which had a moderate coefficient. For pwMS, there were moderate to excellent associations between BBT and the NHPT and FTT for both upper limbs. The correlations between hand grip strength and FFT were poor. This mobile app could be a useful and low-cost assessment tool in pwMS, allowing a simple evaluation and follow-up that has excellent correlation with clinical scales validated in this pathology.

In couples dealing with health problems, we-disease appraisals can influence dyadic coping strategies to alleviate distress. This study describes the development and validation of a self-report scale to assess we-disease appraisals of health problems. The newly developed We-Disease Questionnaire (WDQ) was administered in three samples: parents of children with type 1 diabetes (n = 240) or cancer (n = 125) and individuals with visual impairment and their partners (n = 216). Reliability was measured by coefficient omega. To assess construct validity, correlations with other measures of individual and dyadic adjustment were examined. Descriptive statistics across all samples were compared. A 4-item version of the WDQ demonstrated good reliability and validity and showed meaningful associations with established scales. We-disease appraisals were highest among parents of children with cancer and lowest among couples with visual impairment. The WDQ is a reliable and valid measure that can be used across different health problems. [ABSTRACT FROM AUTHOR]

Uniaxial compressive strength is a variable necessary for adequately characterizing a material's mechanical properties. However, a specimen's geometric deviations and elastic properties may lead to undesirable stress states, which cause strong discrepancies between the results of the uniaxial compression test and its theoretical foundations. While geometric deviations may cause non-uniform contact between the platen and the specimen, elastic properties can provoke severe end effects that disturb the local stress field near the points of contact. To address how the relative stiffness between the platen and the specimen influences the induced stress field, numerical simulations considering the stiffness ratios E p / E s = 3 , E p / E s = 1 and E p / E s = 0.05 were performed. Subsequently, these results were employed to establish the relation between relative stiffness and specimen failure patterns in brittle materials, particularly in three different rocks. The results prove that the platen stiffness must be accurately selected to match that of the tested material, in order to avoid undesirable local stress fields near the point of contact and to induce homogeneous uniaxial compression that guarantees reliable uniaxial compressive strength characterization. Furthermore, the brittle failure patterns reported in previous studies were correlated with the induced stress fields inside the specimen depending on its platen stiffness, allowing the validity of the test results to be verified based on a simple visual inspection.

Background: The only complete and validated tool for evaluating professional orchestra musicians is the English-language Musculoskeletal Pain Intensity and Interference Questionnaire for professional orchestra Musicians (MPIIQM) questionnaire, which, in recent years, has been translated, adapted, and validated in other languages. The aim of the study was to validate the online version of the Polish version of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM-P). Materials and Methods: The group included 182 professional musicians. The respondents were asked to complete the MPIIQM-P, BPI, and QuickDash questionnaires twice within an interval of 4 days. The questionnaires were created in the web form creator—Google Form. Results: The EFA analysis showed a two-factor structure of the questionnaire consisting of factor 1—pain intensity and factor 2—pain interference. The internal agreement of the factors identified in the EFA analysis was measured by the α Cronbach index reaching from 0.813 to 0.913. The intraclass correlation coefficient of both factors ranged from 0.276 to 0.583. The analysis of convergent and divergent validity between the subscales of the questionnaire value ranged from 0.414 to 0.925. Conclusions: The online version of the MPIIQM-P questionnaire is a valid and reliable tool for the assessment of musculoskeletal pain and interference. The online MPIIQM-P questionnaire maintains the psychometric properties previously defined for the paper version. [ABSTRACT FROM AUTHOR]

The need for certification standards for new convergence products, such as a smart LED streetlight system, has been identified as a critical issue. This study proposes simulation modeling for smart LED streetlight systems and suggests three certification standards: the minimum time to initiate dimming-up, the duration of the dimming-up period, and the number of concurrently controlled streetlights. We utilized Relux to model streetlights and roads in terms of luminance levels, and used analytical formulas to compute the braking distances of oncoming vehicles. The two models were integrated into a smart LED streetlight system model using Simio. Simulation experiments were conducted with two objectives: to provide certification standards, and to apply and verify them in real-world cases. We experimented with 630 scenarios, modeling various dynamic situations involving roads and vehicles, and applied the model to two actual roads in the Republic of Korea to test its validity. The model was subsequently applied to roads for which traffic-volume data were available, to determine potential energy savings. The proposed simulation method can be applied to a smart LED streetlight system and to new products that lack certification standards. Furthermore, the proposed certification standards offer alternative approaches to operating streetlight systems more efficiently. [ABSTRACT FROM AUTHOR]

Two studies were conducted in Hong Kong to validate a brief measure of family resilience based on the three-factor CPR model. The CPR model stipulates that family resilience comprises three major factors: Communication and Connectedness (C), Positive Framing (P), and External Resources (R). Study 1 abbreviated the 16-item Family Resilience Scale (FRS16) into six items (FRS6) with a parent sample in the community (N = 1270). Study 2 tested the validity of the FRS6 with a single parent sample (N = 336). The result of Study 1 suggests a dominant general family resilience factor structure with three distinct subfactors. The highest factor loading items from each of the three subfactors were retained in the six-item FRS6. The resultant FRS6 was internally consistent and related to various correlates in similar or better strengths as compared to the FRS16. The results of a separate sample in Study 2 indicated that the FRS6 demonstrated satisfactory internal reliability and correlated significantly with individual resilience, quality of life, anxiety, and depression in the expected directions. Both studies supported that the FRS6 is a psychometrically sound measure of family resilience and can be used in longitudinal studies that aim to chart the trajectory of family adjustment following life adversities.

The purpose of this study is to carry out the scale development of occupational well-being (OWB) (affective, professional, social, cognitive, psychological and psychosomatic well-being) in Laos. Using multiple sampling data, we developed a valid OWB scale with a large Laotian sample (n = 1745). The validity of the OWB-47 scale was analyzed using exploratory factor analysis (EFA). Cross-validity, the initial model, and confirmatory factor analysis (CFA) were performed using Stata 19 to assess the validity of the scale development. Consistent with the valid model, the CFA revealed a unidimensional structure in the OWB scale. The initial measurement of the OWB scale was significantly correlated with the measure of the six-dimensional model. Regarding the full model testing, the CFA model was developed to test the validity of the OWB-47 scale, suggesting the acceptability of the fit model. [ABSTRACT FROM AUTHOR]

The present study describes the Italian adaptation of the Academic Stressors Scale (E-CEA) of the Academic Stress Questionnaire, evaluating the relationships with general and domain-specific well-being and verifying the significant predictors and the amount of variance explained by the "non-intellective" academic competencies on the scores of student stress dimensions. The participants are 1305 students from all the different degree courses. The Italian version of the E-CEA, composed of 38 items, showed good psychometric properties both in terms of reliability and factorial structure with good fit indices. The 6 sub-dimensions, for the most part overlapping with those of the original version of the instrument, show good construct and concurrent validity as negative relationships were found with general and domain-specific well-being indices. With regard to the regressions performed, several dimensions of "non-intellective" academic competencies turned out to be significant predictors (with negative effect) with respect to the stress levels perceived in the academic environment by university students: in particular, time organization, emotional control, the ability to relate to professors and intrinsic motivation could decrease stress levels, while dedication to study and the tendency to involve one's parents in one's university career seemed to increase stress levels. Regarding the practical implications of the results, suggestions are provided in supporting the career paths of students to reduce risk factors for stress development and to promote academic well-being.

Background: "Ghosting" refers to the practice of abruptly cutting off all contact with a person with whom you have been in constant correspondence. The break comes without warning and without understandable provocation. The term most commonly applies to online romantic relationships. The motives for and effects of ghosting have been studied, and validated research questionnaires have been developed; however, there are no such questionnaires available for Urdu speakers. The purpose of this study was to adapt the "Ghosting Questionnaire (GQ)" for use in Pakistan and India, two of the world's most populous countries—a process that involves translation, adaptation, and validation. Methods: The study's methodology involved translating the GQ into Urdu using both forward and backward translation techniques. Convergent validity, test–retest reliability, internal consistency, confirmatory factor analysis, and goodness of fit were all components of the psychometric analyses. Conclusions: The Urdu version of the GQ demonstrated a good internal consistency, with the Cronbach's alpha and McDonald's omega both exceeding 0.90. It also showed a high test–retest reliability—(0.96). The one-factor structure was confirmed by the confirmatory factor analysis, which agreed with the original English version of the GQ.

Sedentary behaviour (SB) and physical activity (PA) have been shown to be independent modulators of healthy ageing. We thus investigated the impact of activity monitor placement on the accuracy of detecting SB and PA in older adults, as well as a novel random forest algorithm trained on data from older persons. Four monitor types (ActiGraph wGT3X-BT, ActivPAL3c VT, GENEActiv Original, and DynaPort MM+) were simultaneously worn on five anatomical sites during ten different activities by a sample of twenty older adults (70.0 (12.0) years; 10 women). The results indicated that collecting metabolic equivalent (MET) data for 60 s provided the most representative results, minimising variability. In addition, thigh-worn monitors, including ActivPAL, Random Forest, and Sedentary Sphere—Thigh, exhibited superior performance in classifying SB, with balanced accuracies ≥ 94.2%. Other monitors, such as ActiGraph, DynaPort MM+, and GENEActiv Sedentary Sphere—Wrist, demonstrated lower performance. ActivPAL and GENEActiv Random Forest outperformed other monitors in participant-specific balanced accuracies for SB classification. Only thigh-worn monitors achieved acceptable overall balanced accuracies (≥80.0%) for SB, standing, and medium-to-vigorous PA classifications. In conclusion, it is advisable to position accelerometers on the thigh, collect MET data for ≥60 s, and ideally utilise population-specific trained algorithms. [ABSTRACT FROM AUTHOR]

There is a lack of validated measures in Scandinavian languages to track healthcare service needs and delivery for patients with neurological disabilities. The aim of the present study was to validate the Norwegian version of the clinician and patient Needs and Provision Complexity Scale (NPCS) Needs and Gets. Data on the NPCS from 60 adult patients with traumatic brain injury or atraumatic subarachnoid hemorrhage and symptoms lasting >5 months were assessed for inter-rater/test–retest reliability and agreement, as well as concurrent validity with the Neurological Impairment Scale (NIS), the Functional Independence Measure (FIM), and the Community Integration Questionnaire (CIQ). The clinician NPCS showed good–excellent inter-rater reliability, and the patient NPCS demonstrated good–excellent test–retest reliability. Absolute agreement was moderate–excellent across all clinician and patient items. Concurrent validity was significant, with large correlations between clinician NPCS-Needs and the NIS and FIM total scores, and small–medium correlations between the clinician and patient NPCS-Gets and the NIS and FIM total scores. There were no significant correlations between the NPCS and the CIQ. The study findings support the use of the Norwegian version of the NPCS to assess met and unmet healthcare and support needs for Norwegian-speaking adults with neurological disabilities.

Although the 6-Minute Walk Test (6MWT) is among the recommended clinical tools to assess gait impairments in individuals with Parkinson's disease (PD), its standard clinical outcome consists only of the distance walked in 6 min. Integrating a single Inertial Measurement Unit (IMU) could provide additional quantitative and objective information about gait quality complementing standard clinical outcome. This study aims to evaluate the test–retest reliability, validity and discriminant ability of gait parameters obtained by a single IMU during the 6MWT in subjects with mild PD. Twenty-two people with mild PD and ten healthy persons performed the 6MWT wearing an IMU placed on the lower trunk. Features belonging to rhythm and pace, variability, regularity, jerkiness, intensity, dynamic instability and symmetry domains were computed. Test–retest reliability was evaluated through the Intraclass Correlation Coefficient (ICC), while concurrent validity was determined by Spearman's coefficient. Mann–Whitney U test and the Area Under the receiver operating characteristic Curve (AUC) were then applied to assess the discriminant ability of reliable and valid parameters. Results showed an overall high reliability (ICC ≥ 0.75) and multiple significant correlations with clinical scales in all domains. Several features exhibited significant alterations compared to healthy controls. Our findings suggested that the 6MWT instrumented with a single IMU can provide reliable and valid information about gait features in individuals with PD. This offers objective details about gait quality and the possibility of being integrated into clinical evaluations to better define walking rehabilitation strategies in a quick and easy way.

Cyberaggression is an important problem today; it can affect adolescents in different ways. Therefore, reliable and valid measures are necessary to better study the phenomenon. The aim of the present study was to generate validity and reliability evidence for a Spanish-language cyberaggression scale from Garaigordobil, (2017) in a population of 1695 adolescents from northwestern Mexico (51.5% female) between 12- and 15-years-of-age. The results of this study contribute to the research and focus on cyberaggression in adolescents in Mexico. The measure used in this paper detects the different roles, including the bystander, rigorously testing the reliability and validity of the measure, providing a solid tool to evaluate cyberaggression in the Mexican context and guide evidence-based interventions and policies in educational settings.

Highlighting the crucial role of monitoring and quantifying lumbopelvic rhythm for spinal curvature, the Ergotex IMU, a portable, lightweight, cost-effective, and energy-efficient technology, has been specifically designed for the pelvic and lumbar area. This study investigates the concurrent validity of the Ergotex device in measuring sagittal pelvic tilt angle. We utilized an observational, repeated measures design with healthy adult males (mean age: 39.3 ± 7.6 y, body mass: 82.2 ± 13.0 kg, body height: 179 ± 8 cm), comparing Ergotex with a 3D optical tracking system. Participants performed pelvic tilt movements in anterior, neutral, and posterior conditions. Statistical analysis included paired samples t-tests, Bland–Altman plots, and regression analysis. The findings show minimal systematic error (0.08° overall) and high agreement between the Ergotex and optical tracking, with most data points falling within limits of agreement of Bland–Altman plots (around ±2°). Significant differences were observed only in the anterior condition (0.35°, p < 0.05), with trivial effect sizes (ES = 0.08), indicating that these differences may not be clinically meaningful. The high Pearson's correlation coefficients across conditions underscore a robust linear relationship between devices (r > 0.9 for all conditions). Regression analysis showed a standard error of estimate (SEE) of 1.1° with small effect (standardized SEE < 0.26 for all conditions), meaning that the expected average deviation from the true value is around 1°. These findings validate the Ergotex as an effective, portable, and cost-efficient tool for assessing sagittal pelvic tilt, with practical implications in clinical and sports settings where traditional methods might be impractical or costly.

The General Evaluation Scale (GES) has been widely employed to assess attitudes toward outgroups, including ethnic and religious prejudice. However, validation within the Indonesian context has not been conducted. Using two studies (Study 1, religious prejudice; Study 2, ethnic prejudice), we provide evidence of psychometric properties of a six-item GES for measuring ethnic and religious prejudice based on factor structure, composite reliability, and convergent validity in Indonesia. The results demonstrate an acceptable model fit for a single-factor structure characterized by high internal consistency (McDonald's Omega/ω = 0.93 in Study 1, ω = 0.94 in Study 2). Furthermore, the scale exhibits solid convergent validity, as evidenced by its correlations with the blatant and subtle prejudice scale (r = −0.44 in Study 1, r = −0.74 in Study 2) and the feeling thermometer scale (r = 0.60 in Study 1, r = 0.78 in Study 2). In summary, this research unequivocally establishes the GES as a valuable instrument for measuring religious and ethnic prejudice in the Indonesian context, underpinned by its robust psychometric properties. Nevertheless, it underscores the need for further investigations with diverse samples and varying social contexts to bolster the scale's reliability and applicability. [ABSTRACT FROM AUTHOR]
