Abstract
OBJECTIVE: The need to promote awareness of dementia prevention is broadly emphasized in Israel. Currently, there is no valid version of a Hebrew questionnaire to assess attitudes and beliefs related to dementia prevention. This study aimed to translate and validate the MCLHB-DRR questionnaire among the general Israeli population. METHODS: A total sample of 328 participants between the ages of 50-83 years (mean = 58.7, SD = 6.9) were included in this study. Participants completed the online translated MCLHB-DRR questionnaire. Exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) were conducted to assess the questionnaire's validity. Internal consistency was assessed using Cronbach's alpha. RESULTS: The EFA analysis revealed a seven-factor model with 27 items. One item related to perceived barriers and two items related to perceived severity were deleted. The CFA analysis confirmed a good model fit with the deleted items (χ(2)/df = 2.146, CFI = 0.930, TLI = 0.916, RMSEA = 0.049). Cronbach's alpha values ranged from 0.61 to 0.92. CONCLUSIONS: The Hebrew MCLHB-DRR questionnaire is a valid and reliable measurement tool for assessing attitudes and beliefs related to health behaviours and lifestyle changes for dementia risk reduction in Israeli adults over the age of 50.
