The assessment of occupational functioning (AOF) is a screening tool used to collect a broad range of information to influence a person’s occupational performance and to identify areas needing more in depth evaluation. It is based directly on the model of Human Occupation (Kielhofner, 1985) and measures the throughput of the human system as defined by this practice model. Therapists using this model should be familiar with the practice model. The AOF does not attempt evaluation of specific daily living skills or environmental variables directly but aims to efficiently generate a picture of numerous complex and interrelated factors likely to influence a persons ability to function.
There are two versions that I’ve seen. The first is a straight Interview. The second, called the collaborative version, is part self report, part interview.
