Abstract Background: The Warwick Edinburgh Mental Well-Being Scale (WEMWBS) is a measure of subjective well-being and assesses eudemonic and hedonic aspects of well-being. However, differential scoring of the WEMWBS across gender and its precision of measurement has not been examined. The present study assesses the psychometric properties of the WEMWBS using Measurement Invariance (MI) between males and females and Item Response Theory (IRT) analyses. Method: A community sample of 386 adults from the United States of America (USA), United Kingdom, Ireland, Australia, New Zealand, and Canada were assessed online (N = 394, 54.8% men, 43.1% women, Mage = 27.48, SD = 5.57). Results: MI analyses observed invariance across males and females at the configural level and metric level but non-invariance at the scalar level. The graded response model conducted to observe item properties indicated that all items demonstrated, although variable, sufficient discrimination capacity.Conclusions: Gender comparisons based on WEMWBS scores should be cautiously interpreted for specific items that demonstrate different scalar scales and similar scores indicate different severity. The items showed increased reliability for latent levels of ∓ 2 SD from the mean level of SWB. The WEMWBS may also not perform well for clinically low and high levels of SWB. Including assessments for clinical cases may optimise the use of the WEMWBS.

Abstract Background The present study considers a measure of positive body image, the Body Appreciation Scale-2, which assesses acceptance and/or favourable opinions towards the body (BAS-2). Potential variations of the psychometric properties of the scale across males and females, as well as across its different items invite for further investigation. The present study contributes to this area of knowledge via the employment of gender Measurement Invariance (MI) and Item Response Theory (IRT) analyses. Methods A group of 386 adults from Australia, Canada, New Zealand, Ireland, the United Kingdom, and the United States of America (USA) were assessed online (N = 394, 54.8% men, 43.1% women, Mage = 27.48; SD = 5.57). Results MI analyses observed invariance across males and females at the configural level, and non-invariance at the metric level. Further, the graded response model employed to observe IRT properties indicated that all items demonstrated, although variable, strong discrimination capacity. Conclusions The items showed increased reliability for latent levels of ∓ 2 SD from the mean level of Body Appreciation (BA). Gender comparisons based on BAS-2 should be cautiously interpreted for selected items, due to demonstrating different metric scales and same scores indicating different severity. The BAS-2 may also not perform well for clinically low and high BA levels. Thus, it should optimally be accompanied by clinical interviews for formal assessment in such cases.

The idea of materialism is one of the most important in modern consumer behaviour literature. In this article we have attempted at studying this component using the celebrated Richins and Dawson (1992) scale, where the required data has been collected using the standard instrument. This data is analyzed with the help of the mechanisms of item response theory (IRT). Specifically the graded response model has been used to analyze and get an insight into the problem of subjective well-being. Item response theory is an increasingly popular approach for development, evaluation and administration of psychological measures. We have used in this article one of the three IRT fundamentals, namely, the item response functions. We next illustrate how IRT modelling can be put to use to analyze the data collected in the study of the judgement component of subjective well-being. To that end, we have used the grm() function available in R. The results obtained are thereafter interpreted.

Abstract Background: The present study considers a measure of positive body image, the Body Appreciation Scale-2, which assesses acceptance and/or favourable opinions towards the body (BAS-2[29]). Differential functioning of the scale across the two genders, as well as its items, has not been excluded. The present study contributes to this area of knowledge via the employment of gender Measurement Invariance (MI) and Item Response Theory (IRT) analyses. Methods: A group of 386 adults from the community were assessed (N = 394, 54.8% men, 43.1% women, M age = 27.48; SD = 5.57). Results: MI analysis observed invariance across males and females at the configural level, and non-invariance at the metric level. Further, the two-parameter logistic model employed to observe IRT properties indicated that all items demonstrated, although variable, strong discrimination capacity. Conclusions: The items showed increased reliability for latent levels of ∓ 2 SD from the mean level of Body Appreciation. The implications and interpretations of the findings for clinical practice are discussed.

ObjectivesTo validate and test the dimensionality of six constructs from the Workplace Integrated Safety and Health (WISH) assessment, an instrument that assesses the extent to which organisations implement integrated systems approaches for protecting and promoting worker health, safety and well-being, in a sample of nursing homes in the USA.DesignValidation of an assessment scale using data from a cross-sectional survey.SettingNursing homes certified by the Centers for Medicaid and Medicare services in three states of the USA: Ohio, California and Massachusetts.Participants569 directors of nursing from nursing homes serving adults and with more than 30 beds participated in the study.ResultsGraded response Item Response Theory (IRT) models showed that five out of six constructs were unidimensional based on balanced interpretation of model fit statistics—M2 or C2 with p value >0.05, Comparative Fit Index >0.95, lower bound of the root mean squared error of approximation 90% CI <0.06 and standardised root mean square residual <0.08. Overall measure and construct reliability ranged from acceptable to good. Category boundary location parameters indicated that items were most informative for respondents in lower range of latent scores (ie, β1, β2, β3 typically below 0). A few items were recommended to be dropped from future administrations of the instrument based on empirical and substantive interpretation.ConclusionsThe WISH instrument has utility to understand to what extent organisations integrate protection and promotion of worker health, safety and well-being; however, it is most informative in organisations that present lower scores.

There continues to be a lack of fundamental knowledge regarding assessment, conceptualization, and treatment of teen dating violence (TDV). This deficiency of knowledge becomes even greater when examining gender differences in violence experience, perpetration, and perception. This article details the item response theory (IRT) analysis of the Teen Screen for Dating Violence (TSDV) and includes an assessment of differential item functioning (DIF) reported by gender. The TSDV examines adolescents’ perception, experience, perpetration, and exposure to violence, while also exploring support systems. The study participants included males and females between 13 and 21 years of age. Further refinement of the TSDV contributes to a more accurate and comprehensive conceptualization of TDV measurement. The results of this study support the use of the TSDV to assess for TDV in the adolescent population. The DIF analysis reveals that many of the items function differently for males and females, which provides evidence indicating that how TDV is experienced, perceived, and perpetrated differs across gender. The TSDV can assist clinicians in early TDV prevention, intervention, and education for males and females. It can also assist researchers in more accurately estimating perpetration, experience, and conceptualization of the three violence facets (emotional, physical, and sexual) in males and females. To further expand TDV knowledge, we offer recommendations for the use of the TSDV in various settings. The TSDV is a vital tool for clinicians, supervisors, and researchers to implement to mitigate the TDV epidemic and help bridge the gap in mental health services.
