Clinical utility, validity and reliability of the IPad application for goal-setting: The aid for decision-making in occupation choice-2.

ObjectiveTo evaluate the clinical utility, reliability, and validity of the second-generation aid for decision-making in occupation choice-2 (ADOC2), an iPad application designed for client-centred and occupation-centred goal setting.DesignThis study consisted of two components: (1) The development and refinement of the ADOC2 application, focusing on user interface design and structured goal-setting functionality; and (2) the clinical evaluation of its utility, validity, and reliability.SettingEleven rehabilitation facilities in Japan (10 hospitals, 1 home-based setting).ParticipantsA total of 116 occupational therapy clients and 56 occupational therapists participated in the study.Main measuresClinical utility was assessed using a structured questionnaire previously validated for the original ADOC. Validity was examined through correlations with the Canadian Occupational Performance Measure (COPM) and the EuroQol 5-Dimension 5-Level (EQ-5D-5L). Test-retest reliability of satisfaction and performance scores was analysed using weighted kappa coefficients.ResultsOver 90% of participants reported positive experiences with ADOC2 during the goal-setting process. The COPM scores showed strong correlations with ADOC2 ratings, while EQ-5D-5L scores showed weaker but expected correlations. Weighted kappa analyses indicated substantial to almost perfect agreement for test-retest reliability.ConclusionsADOC2 is a clinically useful, valid, and reliable tool for facilitating client-centred goal setting in occupational therapy practice.
