Abstract
Introduction: Participating in meaningful activities that reflect one’s identity promotes the wellbeing of elderly people. This study aimed to prepare a questionnaire draft to evaluate occupational identity of the elderly and to examine the content and face validity of the questionnaire.
Methods: First, we generated questionnaire items to evaluate the occupational identity of elderly people. Second, a content validity study was conducted with experts, using three rounds of the Delphi method. Lastly, the face validity study was undertaken by elderly participants, who reported on whether they could understand the questionnaire.
Results: The 50 original questionnaire items were reduced to 21 items with the Delphi method. The items showed item-level content validity index （I-CVI） ranging between 91.7% and 100%, and scale-level CVI with the universal average method （S-CVI/Ave） of 97.4%, which fulfilled the consensus criteria. In the result of the face validity, although none of the items were checked as “Difficult to understand,” there were four items checked as “Difficult to answer.” Accordingly, only one item was corrected.
Conclusion: Results suggest that this assessment possesses content and face validity in a sample of elderly people. The questionnaire is likely to allow occupational therapists to gain information about elderly peoples’ occupational identity.
