Investigation of reliability and validity of the Turkish version of the participation motivation questionnaire for older adults (PMQOA)

Abstract Background: This study aims to determine the psychometric properties of the World Health Organization Well-Being Index (WHO-5) Turkish version in Turkish adults and older adults. Methods: This is a multicenter cultural adaptation study carried out with 1752 participants. Internal consistency (by Cronbach’s alpha); Construct validity (by known groups and confirmatory factor analysis-CFI) and discriminant validity are evaluated stratified by adults and older adults. Cohen’s Effect Size is used in known groups and discriminant validity analyses. Results: Distribution properties of the WHO-5 Turkish version are in acceptable limits. Alpha values are 0.81 for adults and 0.86 for older adults. The variances of the 58.5% of the adults sample and 63.9% of the older adults sample are explained in Exploratory FA. Model fits (CFI) are satisfactory ( > 0.95) in both samples; but RMSEA is poor in the older adults sample (0.166) whereas it is acceptable (0.073) in the adults sample. Known groups validity and discriminant analyses are satisfactory in both adults and older adults. Conclusion: The WHO-5 Turkish version has a good measurement capacity, internal consistency and good model fits in both samples. The error values in the older adults group suggest that the results when testing older adults should be interpreted with caution.

The ability to screen Turkish-speaking older adults for cognitive impairment by phone is lacking. The aim of this study was to translate the existing version of the telephone cognitive screen (T-CogS) into Turkish version (T-CogS-TR) and evaluate its reliability and validity in community-dwelling older adults. We prospectively recruited 104 community-dwelling participants with mild to moderate Alzheimer’s disease (AD) and healthy controls. The T-CogS-TR was administered twice via telephone at home, first within 3 days of an in-person administration and again 4 weeks later. We observed acceptable internal consistency (Cronbach α coefficient = 0.738) and internal reliability. The test–retest reliability was excellent. The T-CogS-TR demonstrated significant correlations with Instrumental Activities of Daily Living, Mini-Mental State Examination, Clock-Drawing Test, and Clinician Dementia Rating ( P’s < .0001). The cutoff value of ≤22 exhibited sensitivity of 96.8%, specificity of 90.2%, positive predictive value of 93.9%, and negative predictive value of 94.9%. The T-CogS-TR can be useful as a valid and reliable tool for detecting AD in Turkish elderly patients. Also, this tool may be considered suitable for patients who need more frequent follow-up and cannot easily return to in-person visits.

Background: In older adults, depression symptoms may be masked by physical complaints and be even attributed to the natural aging process, which may be resulted in improper diagnosis. Native-language scales can be highly effective in the detection of depressive disorders. In this study we attempted to assess the reliability and validity of the Azeri Turkish version of the geriatric depression scale (GDS). Methods: In this psychometric study, the GDS and the Structured Clinical Interview for DSM IV(SCID) questionnaires were administered to a sample of 387 older adults (60 years and older)from the member households of Tabriz health centers. The English version of GDS was translated into Azeri Turkish. Translation-back translation process was conducted. The receiver operating characteristics (ROC) curve, as well as sensitivity and specificity, were used to determine the validity of the questionnaire, and the test-retest method was used to calculate reliability. Results: The mean age of participants was 69.30. The area under the ROC curve for the scores higher than five was 0.832 and for the scores equal to ten and above was 0.871. The sensitivity and specificity for the scores higher than five were 90.9% and 73.4%, respectively. The reliability of this scale was confirmed based on intraclass coefficient (ICC) = 0.79. Conclusion: The Azeri Turkish version of GDS was found with appropriate levels of validity and reliability.
