Reliability and validity of individualized satisfaction score in aid for decision-making in occupation choice

Abstract

Purpose: The iPad application aid for decision-making in occupation choice (ADOC) was developed to measure the client’s satisfaction with individualized occupational performance of meaningful and purposeful activities. The present study examined the reliability and validity of individualized satisfaction measurement using the ADOC. Method: The Japanese version of the ADOC was used by 36 occupational therapists on 92 of their clients (44 males, 48 females, mean age 66.4 ± 17.8 years). Convergent and discriminant validity were examined using Pearson’s correlation between ADOC satisfaction score and the Life Satisfaction Index K (LSIK) factors: Factor 1 (satisfaction with life), Factor 2 (optimistic and positive disposition) and Factor 3 (evaluation of own aging). Test–retest reliability was assessed using the intraclass correlation coefficient (ICC). Results: Ninety-two clients completed the validation study. Satisfaction with ADOC significantly correlated with LSIK Factor 1 (r = 0.297, p < 0.01), but not with Factors 2 or 3 (r = −0.045 and −0.089, respectively). Of the 92 clients, 78 participated in the test–retest reliability study. Good to moderate correlation was revealed (ICC = 0.712, p < 0.001). Conclusions: The Japanese version of the ADOC is a valid and reliable instrument for measuring client satisfaction with individualized occupational performance.

Implications for Rehabilitation

• The iPad application, aid for decision-making in occupation choice (ADOC), was developed to promote shared decision-making during rehabilitation goal-setting.

• ADOC involves choosing from 95 illustrations related to the item “activities and participation” in International Classification of Functioning, Disability, and Health.

• The Japanese version of ADOC makes it easy to identify and share the meaningful occupation for client, and a valid and reliable tool on measuring client satisfaction with occupation.
