Background and aim: Memory impairment in the elderly has a high prevalence and can affect their performance, interactions and quality of life. A valid and reliable questionnaire is required to investigate the changes in the memory of the elderly. The aim of this study was to investigate the psychometric properties of the Persian version of the Memory Impact Questionnaire (MIQ) in the elderly.
Methods: In this methodological study, 361 elderly people (181 people for exploratory factor analysis and 180 people for confirmatory factor analysis) were selected via convenience sampling. This questionnaire was translated based on the World Health Organization’s (WHO) guidelines. Construct validities were assessed through exploratory and confirmatory factor analyses. Its reliability was also assessed using Cronbach’s alpha coefficient.
Results: In the exploratory factor analysis, three factors of lifestyle restrictions, positive coping, and negative emotion were extracted that were able to explain 54.04% of the total variance of the impact of memory change in the elderly. Confirmatory factor analysis confirmed the goodness of fit of the three-factor model of MIQ (RMSEA: 0.083; GFI: 0.97; NFI: 0.94; IFI: 0.97; PNFI: 0.86; AGFI: 0.75). The reliability of the “lifestyle restrictions”, “negative emotion” and “positive coping” factors was found to be 0.89, 0.74, and 0.67, respectively, using Cronbach’s alpha coefficient.
Conclusion: The Persian version of the MIQ is simple and practical and has acceptable reliability and validity that can be used to measure memory changes in the Iranian elderly.
