Abstract:
Objective:To develop a Protection Motivation Questionnaire(PMQ)for frailty management in the elderly based on the Protection Motivation Theory(PMT), and test its reliability and validity.Methods:Guided by PMT, the initial questionnaire items were formulated through literature review, semi-structured interviews, and Delphi expert consultation.A total of 551 elderly patients with frailty from a tertiary hospital in Changsha were investigated.Item screening was conducted via critical ratio method, Cronbach's α coefficient, correlation analysis, and factor analysis.The reliability was assessed through internal consistency and test-retest reliability, while validity was evaluated via content validity and structural validity.Results:The final PMQ comprised 25 items across five dimensions: severity, susceptibility, response efficacy, response cost, and self-efficacy.The overall Cronbach's α coefficient was 0.818, with subscale coefficients ranging from 0.701 to 0.821.The split-half reliability was 0.811, test-retest reliability was 0.929, and content validity indexwas 0.86.Exploratory factor analysis extracted five factors, accounting for 52.0% of the cumulative variance.Confirmatory factor analysis demonstrated good model fit( χ2/df=1.626, RMSEA=0.05, CFI =0.914). Conclusions:The developed questionnaire exhibits strong reliability and validity, serving as an effective tool to assess protection motivation for frailty management in the elderly.
