Abstract Background Instrumental Activities of Daily Living (IADL) limitations are associated with reduced health-related quality of life for people with mild cognitive impairment (MCI). For these people, the assessment of IADL is crucial to the diagnostic process, as well as for the evaluation of new interventions addressing MCI. The Amsterdam IADL Questionnaire Short Version (A-IADL-Q-SV) is an established assessment tool with good psychometric properties that has been shown to be robust to cultural differences in Western countries. The aims of this study were to: (1) cross-culturally adapt and validate the A-IADL-Q-SV for the German-speaking population of Switzerland; (2) investigate its cultural comparability; and (3) evaluate further psychometric properties. Methods The A-IADL-Q-SV German was pretested on clinicians and participants in a memory clinic setting. The psychometric properties and cultural comparability of the questionnaire were investigated in memory clinic settings including participants with MCI or mild dementia, as well as participants with normal cognition recruited from the community. Item response theory (IRT) was applied to investigate measurement invariance by means of differential item functioning to assess item bias. Additionally, the test–retest reliability on scale level, the construct validity through hypothesis testing and the discriminant validity of the A-IADL-Q-SV German were evaluated. Results Ninety-six informants of participants with normal cognition, MCI or mild dementia completed the A-IADL-Q-SV German. The basic assumptions for IRT scoring were met. No meaningful differential item functioning for culture was detected between the Swiss and Dutch reference samples. High test–retest reliability on scale level (ICC 0.93; 95% CI 0.9–0.96) was found. More than 75% of the observed correlations between the A-IADL-Q-SV German and clinical measures of cognition and functional status were found to be in the direction and of the magnitude hypothesized. The A-IADL-Q-SV German was shown to be able to discriminate between participants with normal cognition and MCI, as well as MCI and mild dementia. Conclusions The A-IADL-Q-SV German is a psychometrically robust measurement tool for a Swiss population with normal cognition, MCI and mild dementia. Thus, it provides a valuable tool to assess IADL functioning in clinical practices and research settings in Switzerland. Trial registration This study was registered retrospectively in July 2019 on ClinicalTrials.gov (NCT04012398).

General Self Efficacy

Abstract Background Self-efficacy is important in adolescence and is found to affect adolescents’ physical activity, risk-taking behaviour and health decisions. Self-efficacy describes a person’s belief in own coping abilities. Having good measures of self-efficacy may contribute to more valid knowledge about the potential role of self-efficacy as a health promoting factor in adolescents lives. Several scales measuring self-efficacy exists. One of these is the General Self-Efficacy Scale comprising 10-items. However, there exists several short versions of the scale. In a large cross-sectional study among adolescents in secondary schools in Norway, five of the items from the General Self-Efficacy Scale are used. The aim of this study is to examine the psychometric properties of this short version of the General Self-Efficacy Scale applying Rasch measurement theory. Methods This study is based on cross-sectional data from the Youth Data Survey. The data collection was carried out in lower and upper secondary schools in Norway during 2018. In total, 6646 adolescents responded to a web-based questionnaire. The data were analysed using the partial credit parameterization of the unidimensional Rasch model. Results Preliminary results indicated that the short version had acceptable reliability (person separation index: 0.78). However, the targeting could have been better (mean person location: 1.441). All items had ordered thresholds. One under-discriminating item and three over-discriminating items were identified. Three items displayed differential item functioning with regard to gender and one item displayed differential item functioning for school level. Conclusions Based on our preliminary findings this short version of the General Self-Efficacy Scale has the potential to measure self-efficacy among adolescents, but there are room for improvements. The scale has some shortcomings related to targeting and differential item functioning that needs to be further explored. Key messages The short version of the General Self-Efficacy Scale has the potential to measure self-efficacy in adolescents. The scale has some shortcomings that needs to be further judged.

Abstract Background The aging population increases rapidly across the world. Timely and effective screening of their mental-health problems is important to individuals, families, and the whole society. The Kessler-6 screening measure (K6) is a very popular instrument for non-specific psychological distress. However, few studies have focused on the psychometric properties of this instrument in the older population. Methods The present study employed Mokken scale analysis to evaluate its dimensionality and structure. This study also used differential item functioning (DIF) to examine whether the same structure existed across sex in a national representative sample of old Chinese people. Data were drawn from a public data set, the 2010 China Family Panel Studies (CFPS2010), and responses from a total of 6450 participants aged 60 years old and above (3136 males and 3314 females) were included in the final analysis. Results Mokken scale analysis supported the unidimensional structure of the K6. Differential item functioning (DIF) analysis revealed that two of the six items (“Hopeless” and “Everything was an effort”) were marked for DIF based on the Chi-square. However, their impacts were negligible in terms of McFadden’s pseudo R2. Conclusions The K6 demonstrates adequate psychometric properties in the old Chinese population. The sum of all six items can be used as an indicator of non-specific psychological distress. Differences in the indicator across sex should be considered as a real difference in psychological distress between the female and the male.

This article forms part of a larger study that sought to develop and validate a scale to measure individual and contextual factors associated with adolescent substance use in low-socio-economic status South African communities. The scale was developed to inform the process of designing preventative interventions in these communities. This study assessed the construct equivalence and item bias across different language versions of the scale. Exploratory factor analysis, equality of reliabilities, and the Tucker’s phi coefficient of congruence were employed to assess whether the two language versions were equivalent at a scale level. Differential item functioning analysis was conducted using ordinal logistic regression and the Mantel-Haenszel method at an item level. The findings revealed that there are significant differences between the two groups at a scale level. Items were flagged as presenting with moderate to large differential item functioning. The biased items have to be closely examined in order to decide how to address the bias.

ABSTRACTBackground:The Geriatric Anxiety Scale (GAS; Segal et al. (Segal, D. L., June, A., Payne, M., Coolidge, F. L. and Yochim, B. (2010). Journal of Anxiety Disorders, 24, 709–714. doi:10.1016/j.janxdis.2010.05.002) is a self-report measure of anxiety that was designed to address unique issues associated with anxiety assessment in older adults. This study is the first to use item response theory (IRT) to examine the psychometric properties of a measure of anxiety in older adults.Method:A large sample of older adults (n = 581; mean age = 72.32 years, SD = 7.64 years, range = 60 to 96 years; 64% women; 88% European American) completed the GAS. IRT properties were examined. The presence of differential item functioning (DIF) or measurement bias by age and sex was assessed, and a ten-item short form of the GAS (called the GAS-10) was created.Results:All GAS items had discrimination parameters of 1.07 or greater. Items from the somatic subscale tended to have lower discrimination parameters than items on the cognitive or affective subscales. Two items were flagged for DIF, but the impact of the DIF was negligible. Women scored significantly higher than men on the GAS and its subscales. Participants in the young-old group (60 to 79 years old) scored significantly higher on the cognitive subscale than participants in the old-old group (80 years old and older).Conclusions:Results from the IRT analyses indicated that the GAS and GAS-10 have strong psychometric properties among older adults. We conclude by discussing implications and future research directions.

Abstract Background The Patient Health Questionnaire (PHQ-9) is a widely used self-report questionnaire to screen depression. Its psychometric property has been tested in many populations including health care workers. We used Rasch measurement theory to examine the psychometric properties of PHQ-9 regarding item difficulty, item fit and the differences between subgroups of respondents classified by sex, age, education and alcohol user status, based on the same overall location of participants.Methods In total, 3,204 health care workers of Maharaj Nakorn Chiang Mai Hospital participated and were administered the PHQ-9. Rating scale Rasch measurement modeling was used to examine the psychometric properties of the PHQ-9.Results The data fitted well to the Rasch model and no violations of the assumption of unidimensionality were observed. All 9 items could form a unidimensional construct of overall depressive severity. Suicidal ideation was the least endorsed while sleep problem was the most. No disordered category and threshold of the rating response were observed. No locally dependent items were observed. No items were found to show differential item functioning across age, sex, education and alcohol consumption. The item-person Wright map showed that the PHQ-9 did not target well with the sample, and a wide gap suggesting few or no items exist to differentiate participants at a certain ability level among the PHQ-9 items.Conclusion The PHQ-9 can be used as a screening questionnaire for major depressive disorder as its psychometric property was verified based on Rasch measurement model. The findings are generally consistent with related studies in other populations. However, the PHQ-9 may be unsuitable for assessing depressive symptoms among health care workers who have low levels of depression.

In this study, we examined the psychometric properties of a French version of the Perceived Motor Competence in Childhood (PMC-C) questionnaire. The participants were 219 French-speaking children (aged 5-12 years), recruited from elementary schools in the Canadian Province of Quebec. Results supported the validity and reliability of a second-order confirmatory factor analytic (CFA) model, including one higher-order factor. Additional analyses supported the complete measurement invariance of the first- and second-order factor structure across sex and indicated no differential item functioning or latent mean differences in PMC-C factors as a function of selected predictors (i.e., age, body mass-index and physical activity/sport involvement). Thus, this French version of the PMC-C has satisfactory psychometric properties (i.e., factor validity and reliability, measurement invariance and differential item functioning) and can be used to assess French-speaking children’s perceived motor competence.

OBJECTIVES: the objective of this study was to evaluate the items contained in the Brazilian version of the Power as Knowing Participation in Change Tool (PKPCT). METHOD: investigation of the psychometric properties of the mentioned questionnaire through Rasch analysis. RESULTS: the data from 952 nursing assistants and 627 baccalaureate nurses were analyzed (average age 44.1 (SD=9.5); 13.0% men). The subscales Choices, Awareness, Freedom and Involvement were tested separately and presented unidimensionality; the categories of the responses given to the items were compiled from 7 to 3 levels and the items fit the model well, except for the following/leading item, in which the infit and outfit values were above 1.4; this item has also presented Differential Item Functioning (DIF) according to the participant's role. The reliability of the items was of 0.99 and the reliability of the participants ranged from 0.80 to 0.84 in the subscales. Items with extremely high levels of difficulty were not identified. CONCLUSIONS: the PKPCT should not be viewed as unidimensional, items with extremely high levels of difficulty in the scale need to be created and the differential functioning of some items has to be further investigated.
