“…A substantial DIF item indicates that the item description has different difficulties for different subgroups of respondents (different genders in this study). 42 We adopted the usual method to identify DIF items: a DIF contrast (ie, the difference of difficulty between 2 groups) of greater than 0.5 suggests a substantial DIF. 43 We examined the relationship between MARS-5 and the MPR using the Pearson correlation coefficient.…”

Background: There is a lack of feasible and validated measures to self-assess medication adherence for older patients with stroke. In addition, the potential determinants of medication adherence for older patients with stroke remain unclear. Objectives: The aims of this study were to (1) examine the psychometric properties of a 5-item questionnaire on medication adherence, specifically the 5-item Medication Adherence Report Scale (MARS-5), and (2) explore the determinants of medication adherence. Methods: Stroke patients older than 65 years (N = 523) filled out the MARS-5 and the Hospital Anxiety and Depression Scale. The medication possession rate (MPR) was calculated to measure the objective medication adherence. Several clinical characteristics (stroke types, blood pressure, comorbidity, HbA1c, quantity of prescribed drugs, fasting blood glucose, and total cholesterol) and background information were collected. We used Rasch analysis with a differential item functioning test to examine psychometric properties. Results: All 5 items in the MARS-5 fit in the same construct (ie, medication adherence), no differential item functioning items were displayed in the MARS-5 across gender, and the MARS-5 total score was strongly correlated with the MPR (r = 0.7). Multiple regression models showed that the MARS-5 and the MPR shared several similar determinants. In addition, the variance of the MARS-5 (R 2 = 0.567) was more than that of the MPR (R 2 = 0.300). Conclusions: The MARS-5 is a feasible and

“…A higher score indicates a higher QoL [23]. In addition to its good psychometric properties in the general Taiwanese population (α = 0.70–0.77), the WHOQOL-BREF had satisfactory reliability and validity in populations with psychiatric problems [24, 25], with cancer [26], and with geriatric problems [27]. …”

BackgroundIn this study, we examined the psychometric properties of the Affiliate Stigma Scale to measure affiliate stigma for caregivers of family members with dementia, a topic scantily covered in the literature.MethodsTwo hundred seventy-one caregivers were recruited. Each completed the Affiliate Stigma Scale, Caregiver Burden Inventory, Taiwanese Depression Questionnaire, Beck Anxiety Inventory, and 28-item World Health Organization Quality of Life questionnaire. The data were evaluated for internal consistency and concurrent validity, and they were analyzed using Rasch statistics and confirmatory factor analysis (CFA).ResultsCFA and Rasch analysis suggested that the Affiliate Stigma Scale contains three underlying unidimensional concepts (cognition, affect, and behavior). The three concepts had satisfactory internal consistency (α = 0.822–0.855) and concurrent validity (r = 0.290–0.628 with caregiver burden, 0.391–0.612 with depression, 0.367–0.467 with anxiety, and −0.590 to −0.365 with quality of life).ConclusionsThe Affiliate Stigma Scale is a promising instrument with sound psychometric properties for measuring affiliate stigma. Healthcare providers might want to use it to understand the caregivers’ perspectives and to design appropriate interventions to decrease their affiliate stigma.

AbstractThis research aimed to evaluate the validity evidences of a unidimensional approach to WHOQOL-BEF in older adults. The instrument was applied to a probabilistic sample of 510 older adults from Bucaramanga and Manizales beneficiaries of day care institutions. Rasch analyses of category function, item and person fit, differential item functioning, unidimensionality and reliability analyses were performed. The category structure had to be collapsed from five to four choices. All items and a high proportion of older adults showed adequate adjustment to the Rasch model. Differential item functioning was identified in five items, although their impact on overall measure was low. Internal consistency was 0.92 and item reliability 0.98. Wright's map is presented. A unidimensional, interval-scale measure of quality of life can be obtained from the WHOQOL-BREF for older adults.
