Convergent validity and responsiveness to change of the single-item physical activity measure were assessed in adults aged 60 years and older, at baseline (n = 205) and 6 months (n = 177) of a health promotion program, Choose to Move. Spearman correlations were used to examine associations between physical activity as measured by the single-item measure and the Community Health Activities Model Program for Seniors (CHAMPS) questionnaire at baseline and for 6-month change in all participants and for sex and age (60–74 years, and ≥75 years) subgroups. Effect size assessed responsiveness to change in physical activity for both tools. Baseline physical activity by the single-item measure correlated moderately with physical activity by the CHAMPS questionnaire in all participants and subgroups. Correlations were weaker for change in physical activity. Effect size for physical activity change was larger for the single-item measure than for the CHAMPS questionnaire. The single-item measure is a valid, pragmatic tool for use in intervention and scale-up studies with older adults.

Collecting real-world evidence via ‘at home’ assessments in ambulatory patients or healthy volunteers is becoming increasingly important, both for research purposes and in clinical practice. However, given the mobile technology that is frequently used for these assessments, concise assessments are preferred. The current study compared single-item ratings with multiple-item subscale scores of the same construct, by calculating the corresponding Bland and Altman 95% limits of agreement interval. The analysis showed that single-item ratings are usually in good agreement with assessments of their corresponding subscale. In the case of more complex multimodal constructs, single-item assessments were much less often in agreement with multiple-item questionnaire outcomes. The use of single-item assessments is advocated as they more often incorporate assessments of all aspects of a certain construct (including the presence, severity, and impact of the construct under investigation) compared to composite symptom scores.

Conditional multi‐item promotions are a prevalent marketing tactic whereby consumers have to buy a certain number of products to get a discount. This paper examines how framing a multi‐item promotion in terms of savings on multiple items versus a single item (e.g., “buy two, get X% off on both” vs. “buy two, get 2X% off on the cheaper item”) affects consumers’ decision‐making and product choices. Two laboratory studies and a field study at a boutique clothing store demonstrate that the “2X% on cheaper” framing makes consumers more likely to select similarly priced primary and secondary items. This strategy is driven by increased focus on promotional savings under the “2X% on cheaper” framing, which leads consumers to spend more on their secondary items. Overall, this research shows how a subtle change in the framing of multi‐item promotions changes consumers’ product selection strategies and shopping basket composition.

Background OPTION5 is a scale used to evaluate shared decision making (SDM) in health care from an observer’s perspective; however, to date, there is no simplified Chinese version of this scale. Objectives This study aims to produce a simplified Chinese version of the OPTION5 scale and to test its psychometric properties. Methods One rater observed and audio-recorded consultations between general practitioners (GPs) and chronically ill patients in a Beijing community health service center (CHSC) from May to June 2019. Meanwhile, demographic data of the patients and GPs were collected via information forms. Two raters assessed inter- and intra-rater reliability by calculating the intraclass correlation coefficient (ICC) and weighted Cohen’s Kappa values. Internal consistency was assessed using Cronbach’s α value. Concurrent was calculated by Spearman’s rank correlation coefficient. Results A total of 209 consultations were recorded and evaluated. As concerns inter-rater reliability, the ICC of the OPTION5 was 0.859 on the total score level, with Cohen’s weighted k ranging from 0.376 (item 5) to 0.649 (item 2) on the single item level. With regard to intra-rater reliability, the ICC was 0.945 on the total score level, with Cohen’s weighted k ranging from 0.469 (item 5) to 0.883 (item1) on the single item level. Cronbach’s α value of all 5 items amounted to 0.746. Spearman’s rank correlation coefficient between OPTION5 and OPTION12 for Chinese versions was 0.660. Conclusions The simplified Chinese version of the OPTION5 scale, developed using stringent translation procedures, demonstrated satisfactory psychometric characteristics. Specifically, inter- and intra-rater reliabilities were excellent, while criterion validity was moderate. The simplified Chinese version of the OPTION5 scale can be implemented in clinical settings to evaluate SDM of treatment during consultations between GPs and chronically ill patients.

Aim The purpose of this study was to explore the utility of two single-item self-report (SR) questions to assess physical inactivity in patients with heart failure (HF). Methods and results This is a cross-sectional study using data from 106 patients with HF equipped with accelerometers for 1 week each. Two SR items relating to physical activity were also collected. Correlations between accelerometer activity counts and the SR items were analysed. Patients were classified as physically active or inactive on the basis of accelerometer counts, and the SR items were used to try to predict that classification. Finally, patients were classified as having high self-reported physical activity or low self-reported physical activity, on the basis of the SR items, and the resulting groups were analysed for differences in actual physical activity. There were significant but weak correlations between the SR items and accelerometer counts: rho = 0.24, P = 0.016 for SR1 and rho = 0.21, P = 0.033 for SR2. Using SR items to predict whether a patient was physically active or inactive produced an area under the curve of 0.62 for SR1, with a specificity of 92% and a sensitivity of 30%. When dividing patients into groups on the basis of SR1, there was a significant difference of 1583 steps per day, or 49% more steps in the high self-reported physical activity group (P < 0.001). Conclusions There might be utility in the single SR question for high-specificity screening of large populations to identify physically inactive patients in order to assign therapeutic interventions efficiently where resources are limited.

Purpose The self-rated health (SRH) item is frequently used in health surveys but variations of its form (wording, response options) may hinder comparisons between versions over time or across surveys. The objectives were to determine (a) whether three SRH forms are equivalent, (b) the form with the best construct validity and (c) the best coding scheme to maximize equivalence across forms. Methods We used data from 58,023 respondents of the Swiss Health Survey. Three SRH forms were used. Response options varied across forms and we explored four coding schemes (two considering SRH as continuous, two as dichotomous). Construct validity of the SRH was assessed using 34 health predictors to estimate the explained variance. Results Distributions of response options were similar across SRH forms, except for the “good” and “very good” options (“good” in form 1: 58.6%, form 2: 65.0% and form 3: 44.1%). Explained variances differed across SRH forms, with form 3 providing the best overall explained variance, regardless of coding schemes. The linear coding scheme maximised the equivalence across SRH forms. Conclusion The three SRH forms were not equivalent in terms of construct validity. Studies examining the evolution of SRH over time with surveys using different forms should use the linear coding scheme to maximise equivalence between SRH forms.

Months after healing, a number of COVID-19 syndrome survivors are affected by both psychological and physical limitations. They are mainly troubled with long-term fatigue, which is a crucial aspect of Long Covid syndrome. This paper aims to investigate the level and persistency of fatigue among COVID-19 survivors from the first wave of the pandemic in Western Liguria and to elucidate the role of gender, age, and lifestyle. It also provides data to the scientific community to help drawing a consistent picture of Long Covid syndrome. The patients were requested to fill a Fatigue Assessment Questionnaire twice: (i) a few weeks after discharge from hospital or home confinement and (ii) a few months later. Statistical analysis was carried out on the global scores and on the score for every single item of the questionnaire. The outcome of the two questionnaires were analyzed separately and compared. Females are more affected by fatigue than males. This results holds for both physical and mental fatigue. All the males’ fatigue scores were reduced at the second control, while 40% of females worsened it. Home-confined patients showed a higher fatigue score at the first check. In the initial stages of the recovery, patients are more affected by physical, rather than mental, fatigue. This is worth of further investigation as well as the reasons leading to a higher initial fatigue score for home cared patients.

Burnout is an important occupational hazard and early detection is paramount in preventing negative sequelae in physicians, patients, and healthcare systems. Several screening tools have been developed to replace lengthy diagnostic tools for large-scale screening, however, comprehensive head–to–head evaluation for performance and accuracy are lacking. The primary objective of this study was to compare the diagnostic performance of five burnout screening tools, including a novel rapid burnout screening tool (RBST). This was a cross-sectional study involving 493 hospital staff (anaesthesiology and intensive care doctors, nurses, and ancillary staff) at the COVID-19 frontline across four hospitals in Singapore between December 2020 and April 2021. The Maslach Burnout Inventory-Human Services Survey (MBI-HSS) was used as the reference standard. Five burnout screening tools, the single-item MBI measure of burnout (SI-MBI), dual-item MBI (DI-MBI), abbreviated MBI (aMBI), Single Item Burnout Question (SIBOQ), and the RBST, were administered via a 36-item online survey. Tools were administered simultaneously and responses were anonymised. Burnout prevalence was 19.9%. The RBST and the SI-MBI had the two highest accuracies (87.8% and 81.9% respectively) and AUROC scores (0.86, 95% CI: 0.83–0.89 and 0.86, 95% CI: 0.82–0.89 respectively). However, the accuracy of the RBST was significantly higher than the SI-MBI (p &lt, 0.0001), and it had the highest positive likelihood ratio (+LR = 7.59, 95% CI 5.65–10.21). Brief screening tools detect burnout albeit with a wide range of accuracy. This can strain support services and resources. The RBST is a free screening tool that can detect burnout with a high degree of accuracy.

While many memory disorders occur with normal rates of forgetting, an accelerated rate of long-term forgetting (ALF) may occur, sometimes in the absence of a learning deficit. Detecting ALF presents a problem as it is desirable that the learned material is re-tested after each of several delays. This may result in earlier retrievals confounding later tests, with evidence suggesting that both positive and negative interaction can occur between successive tests. An earlier study (Baddeley et al., 2019) tested cued recall of a series of four crimes or four visual scenes by probing a different sample of features from all four crimes/scenes at each delay. Even though no question was asked twice, the interpolated tests markedly reduced the rate of forgetting. We suggest that this decelerated forgetting effect may result from the retrieval of probed features activating other associated features within that episode, hence facilitating their recall on subsequent tests. If so, the effect should be removed when only single and separate episodes, or individual items, are tested at each delay. We test this by probing a separate episode at each delay (Experiment 1), or by replacing integrated episodes with recognition memory for isolated words (Experiments 2 and 3) or visual scenes (Experiments 4 and 5). As predicted, we find no reduction in the rate of forgetting, in contrast to our earlier studies. The theoretical and clinical implications of our results are discussed. We conclude that the previously developed Crimes and Four Doors Tests (Baddeley et al., 2019) and the present single item recognition tests are complementary and are both likely to be necessary to ensure the reliable detection of ALF.

Background: The Relationship Questionnaire (RQ) is a commonly used self-reporting questionnaire used to measure adult attachment styles. The RQ has two parts. RQ1, a single item where individuals have to indicate their preferred relationship style, and RQ2, where individuals can rate their relationship style in more detail using four different scales. Agreement is expected between the highest levels selected and the style chosen in RQ1. An advantage of the RQ is its brevity, whereas a disadvantage is that it constitutes a single item. A validation of RQ has not been clearly demonstrated, even though it has convergent validity in relation to other measurements in this area. Methods: 168 patients completed the RQ, the short version of the Experience in Close Relationships (Revised) questionnaire (ECR-R), and scales of depression and interpersonal problems. Regression analysis was conducted to examine the congruity in regard to attachment theory. Results: ratings from 15.5% of the patients showed disagreement between RQ1 and RQ2. Each type of attachment measured by the RQ was predicted by the ECR-R scores, as hypothesized. In the predictive analysis of depression and interpersonal problems, both RQ dimensions and ECR-R scores were coherent. Conclusions: RQ is a valid self-reported measurement that can be applied clinically on the condition that the rater identifies an agreement between RQ1 and RQ2.

Single-item scales are widely used in the field of user experience to report the emotions. However, they are strongly criticized and discouraged by the scientific community. While they have several practical advantages, single-item scales are mainly criticized for their psychometric weakness. Our research explores to what extent single-item scales reflect what a user has experienced during his or her interaction with technology, overall, but also at specific moments such as first and last impressions. This research also explores the sensitivity of these measures across different contexts of use brought by the presence or absence of certain interface features. We conducted a correlational study with 40 users while interacting with financial institution websites. We used two methods to evaluate the experience: lived and measured implicitly using psychophysiological instruments on one hand and self-perceived and measured using single-item scales, on the other hand. Overall, our results suggest limited correlations and in most cases contradictory between lived and perceived experience. We conclude by highlighting the limits to be taken into account when professionals are led to use single-item scales.

We develop a demand postponement mechanism to improve the performance of a single item, periodic review inventory system with advance demand. The focus in the literature has been on how to stimulate customers towards advance demand. Predicting how demand will shift can be problematic, however, and backorders may still occur. We focus on how a firm can address backorders under a given advance demand pattern by a mechanism of compensation from which both the firm and the customers will benefit: the firm may offer a discount to customers for accepting later deliveries at a promised delivery date. Delivery postponement offers are made selectively, i.e. in some periods and to some customers only when there is a benefit for the firm to do so. Customers may decline the offer, but then face the probability of a backorder. In each period, the firm has to decide whether to make delivery postponement offers and for how long, and whether to order from its supplier and how much. We formulate the problem as a Markov Decision Process and solve it by backward induction. Numerical examples illustrate the properties of the state-dependent policies obtained for both uncapacitated and capacitated inventory systems. The postponement mechanism in capacitated systems leads to policies that differ from the threshold policy identified as optimal in the literature. Overall, the approach shows promise to improve system performance more efficiently compared to strategies aiming to increase advance demand in the system.

Background Day-to-day functioning is impaired in major depressive disorder. Yet there are no guidelines to systematically assess these functional changes. This report evaluates prognostic utility of changes in activity impairment to inform clinical decision-making at an individual level. Methods Mixed model analyses tested changes in activity impairment (sixth item of Work and Activity Impairment scale, rated 0–10) at mid-point (week 6) and end of step 1 (weeks 12–14) in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial (n = 2697) after controlling for depression severity [Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR)]. Interactive calculators for end of step 1 remission (QIDS-SR ≤5) and no meaningful benefit (

Based on the multi-item Food Choice Questionnaire (FCQ) originally developed by Steptoe and colleagues (1995), the current study developed a single-item FCQ that provides an acceptable balance between practical needs and psychometric concerns. Studies 1 (N = 1851) and 2 (2a (N = 3290), 2b (N = 4723), 2c (N = 270)) showed that the single-item FCQ scale has good convergent and discriminant validity. Generally, the results showed the highest correlations with the related multi-item dimensions (>0.40). Study 2 refined the scale. Only the items for convenience (Study 2a), sensory appeal (Study 2b) and mood (Study 2c) needed to be revised (as Study 1 showed a correlation between the multi-item and the single-item below the threshold of 0.60). The results also showed comparable predictive validity. Both methods revealed similar association patterns between food motives and consumption behaviours (Fisher’s z tests revealed agreements of 86.2% for Study 1, 92.9% for Study 2a and 100% for Studies 2b and 2c). Study 3 (N = 6062) showed an example of the added value of a context-specific application for the single-item FCQ. Different motives were shown to be relevant across contexts, and the context-specific motives had additional explained variance beyond the general multi-item FCQ. Studies 2b and 3 also showed the performance of the single-item FCQ in an international context. In sum, the results indicate that the single-item FCQ can be used as a flexible and short substitute for the multi-item FCQ. The study also discusses the conditions that should be considered when using the single-item scale.

© Society for Prevention Research 2021, The purpose of this study was to analyze the agreement between self-reported and device-based sedentary time among eight countries in Latin America. As part of the Latin American Study of Nutrition and Health (ELANS), data were collected from 2524 participants (18-65 years) across eight countries. Participants reported time spent sedentary in different activities (computer use at home, videogame use, reading, sitting down to chat with friends/relatives or listening to music, speaking on the phone, watching TV, and riding in a car). Overall sitting time was assessed using a single item from the International Physical Activity Questionnaire (IPAQ). Device-based sedentary time was assessed using Actigraph GT3X accelerometers. Self-reported overall sitting time (227.1 min/day) produced the lowest values of the three assessment methods, followed by self-reported sum of different types of sedentary behavior (364.1 min/day) and device-based sedentary time (568.6 min/day). Overall, correlation coefficients and ICC varied from weak to moderate (rho: 0.25-0.39; ICC: 0.21:0.39) between self-reported sum of different types of sedentary behavior, self-reported overall sitting time, and device-based sedentary time. The Bland-Altman plots indicated low to moderate agreement between self-reported overall sitting time and device-based sedentary time by sex. Self-report measures underestimate sedentary behavior and overall sitting time when compared with device-based measures. The weak and moderate level of agreement between methods indicates that caution is required when comparing associations between different self-report and device-based measures of sedentary behavior with health outcomes.

In this two-study paper we examined three dark-side measures: the short Dark Tetrad measuring four dark-side traits; the SCATI measuring 14 personality disorders (PDs) and the SAPAS a single item measure for each disorder. The first study (N = 502) looked specifically at the new Dark Tetrad. Over 500 British Adults completed it and a confirmatory factor analysis confirmed the Tetrad factor structure. There were large sex differences in half of the items. We also examined demographic, ideological and self-rated correlates which showed ratings of political beliefs and self-rated attractiveness associated with different traits. The second study (N = 273) looked at the correlations between the three measures and the overlap between self-report tests of the same trait. All four of the Tetrad traits correlated with over half of the PDs. We found the highest correlation between the two scores of Narcissism, but that the single measure most associated with Borderline, Depressive and Dependent PD. The discussion considers the use of different clinical and sub-clinical instruments which measure the same variables.

Research on individual differences in the fields of chronobiology and chronopsychology mostly focuses on two – morning and evening – chronotypes. However, recent developments in these fields pointed at a possibility to extend chronotypology beyond just two chronotypes. We examined this possibility by implementing the Single-Item Chronotyping (SIC) as a method for self-identification of chronotype among six simple chart options illustrating the daily change in alertness level. Of 2283 survey participants, 2176 (95%) chose one of these options. Only 13% vs. 24% chose morning vs. evening type (a fall vs. a rise of alertness from morning to evening), while the majority of participants chose four other types (with a peak vs. a dip of alertness in the afternoon and with permanently high vs. low alertness levels throughout the day, 15% vs. 18% and 9% vs. 16%, respectively). The same 6 patterns of diurnal variation in sleepiness were yielded by principal component analysis of sleepiness curves. Six chronotypes were also validated against the assessments of sleep timing, excessive daytime sleepiness, and abilities to wake or sleep on demand at different times of the day. We concluded that the study results supported the feasibility of classification with the 6 options provided by the SIC.

BackgroundTreatment burden is the effort required of patients to look after their health, and the impact this has on their wellbeing. Quantitative data on treatment burden for patients with multimorbidity are sparse, and no single-item treatment burden measure exists.AimTo determine the extent of, and associations with, high treatment burden among older adults with multimorbidity, and to explore the performance of a novel single-item treatment burden measure.Design and settingCross-sectional postal survey via general practices in Dorset, UK.MethodPatients ≥55 years, living at home, with three or more long-term conditions (LTCs) were identified by practices. Treatment burden was measured using the Multimorbidity Treatment Burden Questionnaire. Data collected were sociodemographics, LTCs, medications, and characteristics including health literacy and financial resource. Associations with high treatment burden were investigated via logistic regression. Performance of a novel single-item measure of treatment burden was also evaluated.ResultsA total of 835 responses were received (response rate 42%) across eight practices. Patients’ mean age was 75 years, 55% were female (n = 453), and 99% were white (n = 822). Notably, 39% of patients self-reported fewer than three LTCs (n = 325). Almost one-fifth (18%) of responders reported high treatment burden (n = 150); making lifestyle changes and arranging appointments were particular sources of difficulty. After adjustment, limited health literacy and financial difficulty displayed strong associations with high treatment burden; more LTCs and more prescribed regular medications were also independently associated. The single-item measure discriminated moderately between high and non-high burden with a sensitivity of 89%, but a specificity of 58%.ConclusionHigh treatment burden was relatively common, underlining the importance of minimising avoidable burden. More vulnerable patients, with less capacity to manage, are at greater risk of being overburdened. Further development of a single-item treatment burden measure is required.

The number of older adults is increasing worldwide, including in sub-Saharan Africa (SSA). However, there is a paucity of data on the overall health status of older adults living in SSA. To assess the prevalence and factors associated with poor Self-Rated Health (SRH) among community-dwelling older adults in Lomé, Togo, we conducted a cross-sectional study from January to June 2019 in Lomé among community-dwelling older adults aged 50 years and older. A 30- minute questionnaire was used to collect socio-demographic characteristics, medical history, patterns of medication use and use of herbal products and dietary supplements during a face-to-face interview. SRH was assessed using a single item: Overall, you would say that your health is… (1) excellent, (2) very good, (3) good, (4) fair and (5) poor with response fair or poor defining poor SRH. A total of 344 respondents with median age 63 years, (IQR: 55-72) were enrolled in the study. Women represented 57.6% of the sample. Overall prevalence of poor SRH was 56.4% (95%CI: 51.0-61.9) and was the highest among females (62.6% vs 47.9%; P=0.007) and participants >60 years (61.5% vs 51.1%; P=0.021). Female sex, aged ≥60 years, osteoarthritis, hospitalization within the 12 months preceding the survey, polypharmacy, and the use of herbal products were factors associated with poor SRH (P

Societal pressures for greater sustainability can encourage firms to target part of their innovation activities at ecological initiatives (i.e., eco-innovation). Yet, depending on their value function, firms can respond differently to such pressures and exhibit variance in their eco-innovation activities. In this paper, we investigate the idea that a firm's ownership structure may play a significant role in determining its engagement in eco-innovation. Specifically, we propose that ownership by family blockholders increases the value attached to the company's reputation and that this, in turn, stimulates higher levels of eco-innovation. In other words, we model the company reputation motive as a key mediator in the relationship between family ownership and firm-level eco-innovation. To account for family firm heterogeneity, we also model the moderating role of owners' intention to pass the business on to the next family generation (transgenerational intentions) and of the extent to which these owners reside in the firm's local community (local embeddedness). As theoretical backdrop, our study builds on institutional theory and the mixed gamble logic. To test our hypotheses, we use a large sample of German firms and nonlinear moderated mediation regression analysis. Results reveal that family ownership is positively related to the introduction of eco-innovations by firms, in part because of the stronger emphasis being placed on the company's reputation. We find that this effect is strongest when the owning-family has transgenerational intentions. As such, this study advances our understanding of firm-level drivers of eco-innovation. In view of the prevalence of family-owned firms and the mounting importance of ecological sustainability, it is valuable to extend knowledge on the contingent and indirect effect of family ownership on eco-innovation.

The aim of this study was to verify the association between sociodemographic, general health, and oral health data with self-rated general health (SRGH) and self-rated oral health (SROH) in independent-living older Brazilians. This cross-sectional study was part of a larger study with older individuals living independently in the city of Campinas, Brazil – the “Rede FIBRA” Study (the Frailty in Brazilian Elderly Study). A random sample of 688 older individuals responded the SRGH and 673, the SROH. SRHG and SROH were both assessed using a single item. The questionnaire included sociodemographic, general, and oral health data. The mean age was 72.28 ± 5.4 years. The adjusted analysis revealed that the probability of rating general health as bad was higher for illiterate participants (PR: 1.77, 95%CI: 1.13–2.77) or with low educational level (PR: 1.76, 95%CI: 1.17–2.65), those with depressive symptoms (PR: 1.45, 95%CI:1.21–1.74), participants that self-reported food limitation due to problems with denture or lack of it (PR: 1.29, 95%CI: 1.05–1.56), and those with xerostomia (PR 1.40, 95%CI: 1.17–1.67). The probability of rating general health as bad was lower for participants that presented 0-2 chronic diseases (PR: 0.64, 95%CI: 0.53–0.78) and were pre-frail (PR: 0.76, 95%CI: 0.61-0.96). With regard to SROH, the probability of rating oral health as bad was higher for participants with natural teeth (PR:1.61, 95%CI: 1.24–2.08), that reported xerostomia (PR: 1.44, 95%CI: 1.13–1.84), and food limitation due to problems with denture or lack of it (PR: 1.43, 95%CI: 1.07–1,91), and lower for participants that reported having enough money to cover daily expenses (PR: 0.78, 95%CI: 0.61–0.99). Oral health data and income seem to be related to self-perceptions of general and oral health.

OBJECTIVES: To evaluate the validity of a single-item diet quality measured as a rapid and cost-effective means of dietary assessment among adults living in Puerto Rico (PR), a population with access to and a cultural preference for specific foods. METHODS: This cross-sectional study used data from the PR Assessment of Diet, Lifestyle, and Diseases (2015). Self-perception of diet quality was reported (n = 247, age = 35–75 y) for the current day, young adulthood, and childhood (five-point scale: excellent to poor). We used a culturally adapted food frequency questionnaire to measure dietary intake, and computed diet quality (range: 0–110) with the Alternate Healthy Eating Index-2010 (AHEI). We conducted multivariable generalized linear models to assess relationships between current AHEI and perception of diet quality at three-time points. RESULTS: We categorized current self-rated diet quality into ‘excellent or very good’ (37%), ‘good’ (35%), or ‘fair or poor’ (28%); the overall mean AHEI was 60.1 +/– 11.0. Sensitivity of single-item measure was 60% and specificity was 34%. Current self-rated diet quality was not significantly associated with AHEI score, although adjusted mean scores for fruit and or long-chain fatty acids were significantly lower among participants reporting fair or poor diet, vs. excellent or very good (β = −0.49, 95% CI = −0.97, −0.014; β = −0.52, 95% CI = −0.98, −0.049). In contrast, mean adjusted AHEI score was significantly higher among those rating their diet quality as fair or poor in young adulthood (36%; β = 6.4, 95% CI = 2.4,10.5), and marginally higher among those reporting fair or poor diet quality in childhood (27%; β = 3.99; 95% CI = −0.01,8.04), vs. those rating their diet as excellent or very good, at respective time points. CONCLUSIONS: A single-item perceived diet measure is not a valid assessment of current diet quality for adults in PR. Interestingly, perception of low diet quality in earlier life stages is associated with higher quality of the actual current diet. Nutrition researchers may use self-rated diet quality in earlier life stages to estimate current diet quality; the mechanisms driving this relationship warrant further investigation.

Healthy development can be viewed as an important dimension of the general wellbeing index and can be based upon lifelong sustainable satisfaction. Young individuals can represent an important component for society and its development. The literature shows that increased levels of global life satisfaction (LS) can be associated with minimal levels of problematic behaviors and elevated levels of pro-social behaviors. However, low levels of LS can be associated with high levels of perceived loneliness (PL), which, in turn, can be associated with antisocial behavior (AS). In light of this, the current investigation aims to study the mediating effect of PL and the link between LS and AS. This study is a preliminary investigation referring to aggressive behaviors and cognition in relation to subjective wellbeing. The sample consisted of 81 young individuals (M = 27.57, Standard Deviation = 9.25) from Aurel Vlaicu University of Arad, Romania. AS was evaluated with the How I Think Questionnaire (HIT), PL was measured with a single item inquiry and LS was evaluated with the satisfaction with life scale (SWLS). The results display that there is a powerful association between LS and AS, between LS and PL and between PL and AS. After the inclusion of the mediator (PL) to the model, the influence of the independent variable (LS) increased and the effect of LS on AS significantly decreased. In light of this, the relationship between LS and AS can be explained by the mediating role of the PL variable. The results indicate the importance of perceived loneliness in regard to one&rsquo, s life satisfaction and antisocial behaviors. In light of this, interventions that focus on the social aspect could prove useful for the improvement of sustainable life satisfaction, therefore decreasing the chance of the emergence of AS.

Dyslexia, defined as a specific impairment in decoding the written script, is the most widespread learning difficulty. However, individuals with dyslexia (IDDs) also consistently manifest reduced short-term memory (STM) capacity, typically measured by Digit Span or non-word repetition tasks. In this paper we report two experiments which test the effect of item frequency and the effect of a repeated sequence on the performance in STM tasks in good readers and in IDDs. IDDs’ performance benefited less from item frequency, revealing poor use of long-term single item statistics. This pattern suggests that the amply reported shorter verbal spans in dyslexia may in fact reflect their impaired sensitivity to items’ long-term frequency. For repeated sequence learning, we found no significant deficit among IDDs, even when a sensitive paradigm and a robust measure were used.

(1) Background: This study aims to reflect student nurses&rsquo, perceptions of professional values across the four training years. (2) Methods: This study was designed as a cross-sectional study, data were collected using the Nurses&rsquo, Professional Values Scale-Revised, adapted by Basurto- Hoyuelos. A total of 315 student nurses participated from a Nursing Faculty in Spain representing each of the four academic years. (3) Results: Students&rsquo, perceptions of professional values were significantly correlated with their academic year. Overall, students&rsquo, scores were higher in the ethics dimension. The two highest scores were for Maintain patient confidentiality for years 1 and 2 (4.77 and 4.68, respectively) and Safeguard patients&rsquo, right to privacy for years 3 and 4 (4.95 and 4.98,respectively). Lower scores were observed in the professional expertise dimension across all years, and corresponded to a single item Participate in peer review (3.51, 3.38, 3.98, and 3.26, respectively). (4) Conclusions: This study is relevant as it highlights how nursing students&rsquo, perceptions of professional values change overtime, even during the four years of their training. The ethicsdimension was the most highly regarded across all academic years. However, the professional expertise dimension requires greater attention throughout the degree as students regarded it as lessimportant for their immediate future.

Objective.To evaluate agreement of the updated European League Against Rheumatism and European Scleroderma Trials and Research group (EUSTAR) recommendations for treatment of systemic sclerosis (SSc) among international experts. In addition, to determine factors that might influence agreement.Methods.Level of agreement (10-point scale: 0 = not at all, 10 = completely agree) and local drug availability (yes/no) were assessed using an online survey. The Web link to the survey was shared with 481 unique e-mail addresses and SSc networks (Scleroderma Clinical Trials Consortium, Australian Scleroderma Interest Group, International Systemic Sclerosis Inception Cohort). Level of agreement was compared between subgroups stratified for participant characteristics.Results.In total, 263 experts participated, of whom n = 209 (79%) completed each single item. The majority were rheumatologists (n = 200, 76%) working in Europe (n = 185; 71%); 59% (n = 156) were EUSTAR members; and 57% (n = 151) had > 10 years of clinical experience. Overall level of agreement was high (mean 8.0, SD 2.5). The 3 highest mean agreements included (1) angiotensin-converting enzyme inhibitors for scleroderma renal crisis (9.2, SD 2.1); (2) blood pressure control in SSc-patients treated with corticosteroids (9.0, SD 2.2); (3) proton pump inhibitors to prevent reflux complications (9.0, SD 2.2). The 3 lowest mean agreements included (1) fluoxetine for Raynaud phenomenon (RP; 4.6, SD 2.8); (2) hematopoietic stem cell transplantation (HSCT) for severe SSc (7.1, SD 2.9); (3) phosphodiesterase inhibitors 5 for RP (7.3, SD 2.7). Agreement differed between Europe and non-Europe for the use of iloprost, bosentan, methotrexate, HSCT, and cyclophosphamide. Treatment availability could partially explain differential agreement for iloprost, bosentan, and HSCT.Conclusion.In general, worldwide expert agreement on updated recommendations for treatment of SSc is high, supporting their value. Differences in agreement are partially explained by geographical area and treatment availability.

Objective To determine prevalence of REM sleep behavior disorder (RBD) [prodromal Lewy body disease] in Sun City, Arizona. Patients and methods We attempted, by telephone and mail, a survey using the RBD single item question for probable RBD (pRBD) and the Innsbruck RBD Inventory. Individuals answering “yes” to 4/5 Inventory questions were considered to have high likelihood RBD (HL-RBD.) Results Response rate was 484/3000 individuals contacted (16%), mean age 78; 48 (9.9%) endorsed pRBD by RBD1Q; 16 (3.3%) had HL-pRBD. Prevalence of idiopathic cases (without neurodegenerative disease) was 8.8% pRBD and 2.8% HL-RBD. Conclusion Our estimated definite RBD prevalence of 1.7% (61.3% of HL-RBD) was similar to previous community-based studies., Clinical research; Nervous system; Neurology; Neuroscience; Pathology; Parkinson disease; Dementia with lewy bodies; REM sleep behavior disorder; Lewy body dementia

The goal of the article was to evaluate the pros and cons of using the eNPS indicator and its possible adaptation in employee satisfaction surveys. The author conducted 3 independent surveys on over 6500 employees in 3 different companies. The eNPS results were correlated with questions concerning the general opinion about work and the employer. The eNPS indicator was proven to highly correlate with items describing the general employee opinion about work satisfaction. The numerical value of the indicator itself is considered by the author as misleading due to asymmetry in the classification of positive and negative opinions.

Objective: To assess the roles of demographic factors, actual and perceived risk factors, and perceived control in the referral to cardiac rehabilitation (CR) after coronary artery bypass graft (CABG). Methods: In this cross-sectional study, data related to 312 CABG patients in a hospital of the Western part of Iran, gathered through demographics and actual risk factors’ checklist, open single item of perceived heart risk factors, life stressful events scale, and perceived control questionnaire. Data analyzed by binary logistic regression. Results: The results showed that only 8.3% of CABG patients refer to CR. The facilitators of this referral included official employment (P < 0.05), coronary history (P = 0.016), and hyperlipidemia (P = 0.030) but more distance to the CR center (P = 0.042) and perceived physiological risk factor (P = 0.025) are concerned as the barriers for the referral to CR. Conclusion: Providing appropriate awareness about the benefits of CR for patients with regard to their job status, coronary history, and perception about the illness risk factors can be effective in referral to CR. In addition, the presence of CR centers in towns and facilitated achievement to these centers can play a significant role in patients’ participation.

Self-Determination Theory (SDT) is amongst motivational frameworks the most popular and contemporary approach to human motivation, being applied in the last decades in several domains, including sport, exercise and physical education (PE). Additionally, Achievement Goal Theory (AGT) has presented evidence of how contextual factors may influence student’s behavior in this particular context. The main purpose of this study was to analyze the motivational climate created by the teacher in the classroom, students’ satisfaction of Basic Psychological Needs (BPN), and how their behavioral regulation could explain PE grades and intention to practice sports in the future. Method: A total of 618 students (290 female; 328 male) from the 6th to the 9th school level, aged between 10 and 18 years (M = 13.3; SD = 1.7) participated in this study. The following surveys were used for the proposed variables: Learning and Performance Orientations in Physical Education Classes Questionnaire (LAPOPECQ); the Basic Psychological Needs in Exercise Scale (BPNESp); and the Perceived Locus of Causality (PLOCp). Intentions to practice sport/physical activity in the future were assessed through a single item. Students’ PE grade was obtained through his/her teacher final assessment. Structural Equation Analysis was performed via AMOS 23.0. Results: After analyzing modification indices and model adjustment, the final model emerged: learning climate > BPN > autonomous motivation > intentions/PE grade. Results interpretation seems to indicate that i) the satisfaction of BPN are influenced by motivational climate (i.e., learning climate), ii) the individuals’ motivation is influenced by the satisfaction of three basic psychological needs (i.e., particularly competence), and iii) the motivational regulations have direct and significant effects with intention to practice sports outside school in the future and PE grades. Discussion & Conclusion: The main results showed that a climate oriented for learning has a positive impact on basic psychological needs satisfaction of students. However, only competence satisfaction had a significant positive relationship with students’ autonomous motivation, which in turn had a significant positive relation with PE grade, as well as for intentions for leisure-time sport/physical activity practice.

We study how to maximize the broker's (expected) profit in a two-sided market, where she buys items from a set of sellers and resells them to a set of buyers. Each seller has a single item to sell and holds a private value on her item, and each buyer has a valuation function over the bundles of the sellers' items. We consider the Bayesian setting where the agents' values are independently drawn from prior distributions, and aim at designing dominant-strategy incentive-compatible (DSIC) mechanisms that are approximately optimal. Production-cost markets, where each item has a publicly-known cost to be produced, provide a platform for us to study two-sided markets. Briefly, we show how to covert a mechanism for production-cost markets into a mechanism for the broker, whenever the former satisfies cost-monotonicity. This reduction holds even when buyers have general combinatorial valuation functions. When the buyers' valuations are additive, we generalize an existing mechanism to production-cost markets in an approximation-preserving way. We then show that the resulting mechanism is cost-monotone and thus can be converted into an 8-approximation mechanism for two-sided markets., Appeared in IJCAI 19

BACKGROUND: Working memory (WM) deficits are considered to be a core deficit in schizophrenia, implicated in the broad cognitive impairment seen in the illness. To date, the evidence supporting this view is based on correlations between measures of WM capacity or precision with other cognitive measures. Here we take an experimental approach and directly examine the impact of successful WM maintenance of a single, familiar item on the operation of other cognitive systems. METHODS: We studied 37 healthy controls (HCS) and 43 clinically stable people with schizophrenia (PSZ). Each trial consisted of a sequence of two potential target stimuli, T1 and T2. T1 was an X or a Y, presented for 100 ms. After delays varying from 100–800 ms, T2 was presented. T2 was a 1 or a 2 and required an immediate speeded discrimination response (one button for 1, another for 2). In one block of trials, subjects were instructed to ignore T1 but respond to T2 (attend-T2 trials). In another block, they were required to report T2 at the end of the trial, after making their speeded response to T1 (the attend-T1T2 condition). Thus, the attend-T1T2 condition required subjects to make a speeded response to T2 while holding T1 in WM. 240 trials were tested for each condition. We used median reaction times (RT) as our key dependent measure. The RT difference between attend-T1T2 and attend-T2 trials represents the cost of holding an item in WM. RESULTS: The main finding was that PSZ were dramatically slowed at responding to T2 when T1 was being held in WM (the attend-T1T2 condition). A repeated measures anova yielded main effects of group (PSZ slower), lag (RT longer at shortest T1-T2 intervals, and condition (attend-T1T2 slower than attend-T2; all ps

The single-item predictive validity of the Short-Term Assessment of Risk and Treatability (START) has not been thoroughly investigated, although this has great clinical relevance for the selection of treatment targets. Furthermore, it remains unclear whether the characteristic START additions of scoring strengths next to vulnerabilities and selecting key items, add incremental predictive validity. Finally, predictive validity has primarily been studied in inpatient settings and included mainly patients with a psychotic disorder. We analysed data from a mixed diagnostic sample of 195 forensic psychiatric outpatients with a 3-month and 170 patients with a 6-month follow-up period, using logistic regression analysis. The occurrence of violent or criminal behaviour was established based on the case manager's recordings in the patient's file. Only 5 of the 20 START items were found to have predictive validity: Impulse Control, Attitudes, Material Resources, Rule Adherence and Conduct. The last three were the only items for which incremental predictive validity was found with respect to scoring it as a strength and a vulnerability. Selection of key items did not add to the predictive validity. While possibly having therapeutic significance, the scoring of strength next to vulnerability and the selection of key items, may not be beneficial for risk assessment.
