Aim. The objective of our study has been to evaluate the WHO-5 as a new early screening instrument for apathy in a group of elderly persons.Methods. The WHO-5 was compared to the Geriatric Depression Scale (GDS-15). The GDS contains five items measuring well-being and ten items measuring depression. The internal validity of the WHO-5 (total score being a sufficient statistic) was evaluated with both parametric and nonparametric item response theory models. The external validity of the WHO-5 and the GDS was evaluated by ROC using depression as index of validity.Results. The item response theory analyses confirmed that the total score of the WHO-5 is a sufficient statistic. The ROC analysis shows an adequate sensitivity (61%) and specificity (84%). The GDS15and its two subscales obtained low sensitivity (25–42%), but high specificity (90–98%).Conclusion. The WHO-5 was found both internally and externally valid when considering decreased positive well-being to be an early indication of apathy reflecting that the wind has begun to be taken out of the “motivation sail.”

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.

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 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.

Purpose The purpose of this paper is to examine aspects of how workplace bullying is identified by the Negative Acts Questionnaire-Revised (NAQ-R), with a focus on the appropriateness of its response scale using item response theory (IRT). Design/methodology/approach IRT, in which the probability of a particular item response reflects an underlying latent variable, was used to examine NAQ-R responses from a sample of 1,173 Australian public servants (Study 1), and a representative UK data set (n=3,494; Study 2). Findings Results indicated that problems with the response scale appear to be due to the inclusion of the abstract “now and then” option amongst concrete time options (“never”, “now and then”, “monthly”, “weekly” and “daily”). These results were replicated in Study 2, providing evidence of the robustness of the findings, and suggesting the observations are not sample specific. Research limitations/implications This work has implications for methods employed to identify and measure workplace bullying in research and organisational practice. Inconsistent endorsement of response scale options is a concern when total scores are calculated, or when a number of behaviours being experienced with a particular frequency on the response scale are taken as an indication of bullying having occurred. Originality/value Examining and refining the manner in which workplace bullying is indexed is important for identifying and managing workplace risks to health, safety and well-being.

The present study applied item response theory to examine the psychometric properties of the Asian Adolescent Depression Scale and to construct a short form among 1,084 teenagers recruited from secondary schools in Hong Kong. Findings suggested that some items of the full form reflected higher levels of severity and were more discriminating than others, and the Asian Adolescent Depression Scale was useful in measuring a broad range of depressive severity in community youths. Differential item functioning emerged in several items where females reported higher depressive severity than males. In the short form construction, preliminary validation suggested that, relative to the 20-item full form, our derived short form offered significantly greater diagnostic performance and stronger discriminatory ability in differentiating depressed and nondepressed groups, and simultaneously maintained adequate measurement precision with a reduced response burden in assessing depression in the Asian adolescents. Cultural variance in depressive symptomatology and clinical implications are discussed.
