Abstract
Participation in Instrumental Activities of Daily Living (IADL) is essential in occupational therapy aiming to improve the life situation of elderly. Effective executive function (EF) is important to successful functioning in IADL. The purpose of this study was to examine EF and IADL performance differences according to cognitive levels as measured by the Montreal Cognitive Assessment (MoCA), age, and gender. In all, 80 elderly (49% female; age M = 73.4) were assessed at home, with Weekly Calendar Planning Activity (WCPA-10), IADL scale, and MoCA as a cognitive screening tool for dividing into normal cognitive (NC) level and mild cognitive impairment (MCI). The comparison between the MoCA groups on the WCPA-10 and IADL shows significant differences between the groups; gender and age differed only in IADL. IADL and WCPA-10 performance among independent elderly relates to their cognitive level. We suggest that intervention that will focus on EF may assist in improving performance and maintaining participation in occupation.
