Abstract
BackgroundThe present study aimed to design and determine the psychometric properties of a short-form questionnaire to investigate the domestic elder abuse.MethodsThis study consisted of two phases: in phase 1 we employed a modified Delphi approach with 18 participants. Consequently, content and face validity, and item analysis were applied. In Phase 2 we evaluated structural validity and convergent validity. Reliability was assessed by looking at internal consistency, stability, and absolute reliability.ResultsThe findings led to the development of a 27-items short form of domestic elder abuse in four domains that jointly accounted for 74.14% of the variance observed. The short form showed high internal consistency (Cronbach’s alpha = 0.93) and significantly correlated (r = 0.91; p < 0.001 for both scales) with the comprehensive (49-item) domestic elder abuse.ConclusionThe short form of domestic elder abuse was found to be reliable and valid as the longer version. The short form of domestic elder abuse could lessen the burden on respondents.
