- Previous time-use research suggests that it is highly relevant for an occupational therapist to estimate time use and occupational engagement in order to understand some of the determinants of wellbeing for people with schizophrenia. This article describes the development and the testing of the psychometric properties of an instrument, Profiles of Occupational Engagement in people with Schizophrenia (POES), with the aim of helping to interpret and evaluate time-use diaries and thus providing a systematic description of status regarding occupational engagement. The first part of POES involves completion of time-use diaries and the second part, the assessment, is based on nine items that are rated on a four-point ordinal scale. The time-use diaries of 41 people with schizophrenia and the judgements from 12 occupational therapists were used in the study. A test of content validation involved experts from Sweden and the United Kingdom and resulted in two stages of revisions. The strength of agreement between two raters resulted in a mean weighted kappa of 0.70. Internal consistency was calculated for both raters separately and the alpha coefficients were 0.97 and 0.95. This study provides initial support for the content validity, interrater agreement and internal consistency of POES. Based on the judgements of the occupational therapists in this study, POES seems to have good clinical utility. However, further research on the clinical utility as well as the criterion validity of the construct is warranted.
