Abstract
Objectives Assessment of met and unmet needs of the elderly and how meeting unmet needs can increase the quality of their life. Validity and reliability of any measurement instrument essential to use it for research work. The Aim of this study is to evaluate the test-retest reliability, construct validity and criterion validity of the Persian version of CANE questionnaire as a tool for the assessment of the needs of Iranian elderly people with mental health problems and their informal careers. Methods & Materials This cross-sectional study was done in 2016 on 123 elderly (61 men and 62 women) people with mental health disorder (convenient sampling) with mean age 72 years (SD=9.24) and 41 of their informal careers. To assess test-retest reliability, the interview was conducted twice with two-week interval and criterion validity to measure the correlation between the scores of the Camberwell questionnaire, a 36-item questionnaire assessing the quality of life, Modified Barthel Index, and 12-item General health survey was assessed. Construct validity was assessed by creating a correlation matrix for the first section of all 26 items of the questionnaire. The statistical analyses were performed using the software SPSS 19. Results For test-retest reliability purposes, kappa coefficient elderly (K=0.48-1) and their informal caregivers (K=0.65-1); and Intraclass Correlation Coefficient (ICC) in elderly with 0.95 and their informal caregivers with 0.97, with a significant level of 0.05 were calculated. The results of the criterion validity, high negative Spearman’s correlation between the total score of CANE with total score of the SF36 (r=-0.790) and MBI (r=-0.788) and a moderate correlation between unmet needs score of the CANE with total score SF36 (r=-0.474) and also a high correlation between score of career’s psychological distress item of CANE with total score of GHQ12 (r=0.875) is revealed. The results showed good construct validity of the Persian version of the CANE. Conclusion Test-retest reliability and also construct and criterion validity of the Persian version of the CANE are good. It suggests that for the other studies, the psychometric properties of the Camberwell questionnaire should be evaluated.
