The Fidler’s Life Style Performance Model focuses on knowing and understanding a person’s total activity repertoire within the context relevant to his/her life. This model provides practitioners a complete view of the client and his/her environment. It aims to bridge the gaps among the practice, philosophic constructs of holism, personal relevance, and quality of life. This model proposes that the outcome of occupational therapy intervention is to enable a structure of daily living that has personal, social, and cultural relevance to the client and his/her significant others. The client’s environment is viewed to comprise of interpersonal, societal, cultural, physical, and temporal dimensions which are mutually interactive. In particular, this model consists of a structure of four domains as a guide for occupational therapy intervention:
1. Domain of self-care and self-maintenance, i.e., taking care of one's self and maintaining self-dependence.
2. Domain of intrinsic gratification, i.e., pursuing personally preferred pleasure, enjoyment, and intrinsic gratification.
3. Domain of social contribution, i.e., contributing to the need fulfilment and welfare of others.
4. Domain of interpersonal relatedness, i.e., developing and sustaining reciprocal interpersonal relationships.
To apply this model, practitioners first need to understand client’s characteristic ways of current lifestyle by using the aforementioned four domains within his/her human and nonhuman environment. Then practitioners need to determine in what extend the lifestyle reflects and does not reflect personal and social needs of expectation. An occupational therapy plan for either prevention or remediation mainly includes development life style performance profile, evaluation on performance and environment, and design of a recommended life style performance profiles.
