Abstract
For patients with higher cognitive dysfunction, executive dysfunction is an obstructive factor to work. One of the characteristics of executive dysfunction is that those patients are easily affected by environments. For example, they can perform an activity well in training situations but not in workplace. We assumed that executive functions of the patients are affected by interference of functions to recognize an environment and adopt in it. In this study, we selected 87 case examples of job assistance to patients with higher cognitive dysfunction with conditions such as diagnosis of executive dysfunction and systematic intervention by professionals. Then we abstracted and categorized factors such as functional disorder, restricted activities, limited participation or environment factors according to International Classification of Functioning, Disability and Health: ICF and for those functional disorders, we statistically tested proportional homogeneity based on the proportion of the cases of groups with or without executive dysfunction and found out that impairment of attention, insight or judgment and limitations of maintaining social space are the most relevant factors in the example group of executive dysfunction. In the same manner, in example groups with four disorders or restrictions, we identified functional disorder, restricted activities, limited participation or environment factors that shows meaningfully high ratio of occurrence, then examined relationships with executive dysfunction according to Occupational Performance Process Model: OPPM.
