“…The item fit was assessed using 2 mean square (MnSq): the information-weighted fit statistic (infit) and the outlier-sensitive fit statistic (outfit), in which ranges between 0.5 and 1.5 suggest that the item is well fit. 38,39 Unidimensionality was assessed using principal component analysis on the Rasch-retrieved standardized residuals, in which the first component having an eigenvalue of less than 2 indicates unidimensionality. 29 Person separation reliability reported by the Rasch analysis should be less than 0.7 to indicate adequate consistency in the MARS-5.…”

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

“…Information-weighted fit statistic (infit) mean square (MnSq), and outlier-sensitive fit statistic (outfit) MnSq were used, and both ranges between 0.5 and 1.5 suggested a good fit (Jafari, Bagheri, & Safe, 2012). If an item has MnSq < 0.5, the item could be a redundant item; if an item has MnSq > 1.5, the item could be an out-of-concept item (Khan, Chien, & Brauer, 2013).…”

Background and aimsThe nine-item Internet Gaming Disorder Scale – Short Form (IGDS-SF9) is brief and effective to evaluate Internet Gaming Disorder (IGD) severity. Although its scores show promising psychometric properties, less is known about whether different groups of gamers interpret the items similarly. This study aimed to verify the construct validity of the Persian IGDS-SF9 and examine the scores in relation to gender and hours spent online gaming among 2,363 Iranian adolescents.MethodsConfirmatory factor analysis (CFA) and Rasch analysis were used to examine the construct validity of the IGDS-SF9. The effects of gender and time spent online gaming per week were investigated by multigroup CFA and Rasch differential item functioning (DIF).ResultsThe unidimensionality of the IGDS-SF9 was supported in both CFA and Rasch. However, Item 4 (fail to control or cease gaming activities) displayed DIF (DIF contrast = 0.55) slightly over the recommended cutoff in Rasch but was invariant in multigroup CFA across gender. Items 4 (DIF contrast = −0.67) and 9 (jeopardize or lose an important thing because of gaming activity; DIF contrast = 0.61) displayed DIF in Rasch and were non-invariant in multigroup CFA across time spent online gaming.ConclusionsGiven the Persian IGDS-SF9 was unidimensional, it is concluded that the instrument can be used to assess IGD severity. However, users of the instrument are cautioned concerning the comparisons of the sum scores of the IGDS-SF9 across gender and across adolescents spending different amounts of time online gaming.

“…Acceptable psychometric properties of the KIDSCREN-27 questionnaire have been confirmed in 13 European countries ( Revens-Sieberer et al, 2007 ; Robitail et al, 2007 ). The KIDSCREEN-27 questionnaire was previously translated into Persian and its internal consistency and validity was assessed among Iranian school children ( Jafari, Bagheri, & Safe, 2012 ). All domains in both child self-reports and parent proxy-reports had adequate internal consistency, i.e., Cronbach’s α coefficients were greater than 0.7.…”

This study aims to assess the measurement invariance (MI) of the KIDSCREEN-27 questionnaire across girl-parent and boy-parent dyad to clarify how child gender affects the agreement between children’s and parents’ perception of the meaning of the items in the questionnaire. The child self-reports and parent proxy-reports of the KIDSCREEN-27 were completed by 1061 child-parent dyad. Multiple group categorical confirmatory factor analysis (MGCCFA) was applied to assess MI. The non-invariant items across girl-parent dyad were mostly detected in the psychological well-being and the social support and peers domains. Moreover, the boys and their parents differed mainly in the autonomy and parent relation domain. Detecting different non-invariant items across the girl-parent dyad compared to the boy-parent dyad underlines the importance of taking the child’s gender into account when assessing measurement invariance between children and their parents and consequently deciding about children’s physical, psychological or social well-being from the parents’ viewpoint.
