Person-Environment-Occupation (PEO) model

The Life Balance Model (LBM) focuses on satisfying pattern of healthful, meaningful, and sustainable activities within context of an individual’s current life circumstances. The model purports that the composition of everyday activity should enable people to address these need-based dimensions, they are (1) meeting basic instrumental needs necessary for sustained biological health and physical safety, (2) having rewarding and self-affirming relationships with others, (3) feeling engaged, challenged, and competent, and (4) creating meaning and a positive personal identity.

The Model of Occupational Wholeness focuses on the four dimensions of occupation: doing, being, becoming, and belonging, as well as how these dimensions lead to an individual’s wholeness, health, and wellbeing. This model is illustrated by triangles. A black proportionate triangle illustrates the hypothetical ideal relationship between doing (in the middle), being, become, and becoming (each is a corner of the triangle).

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.

The Lived Environment Life Quality Model (LELQ) aims to explicate the ecological complexities in using occupations to optimize quality of life of institutionalized people with dementia. This model focuses on factors that affect clients’ opportunity in occupational engagement, mainly on the social and physical environmental supports and barriers. It has two main domains, including the lived-environment domain (specifically for assessment and intervention) and the Quality of Life (QoL) domain (specifically for intervention goals and outcome).

The Occupational Performance Model (Australia) is a model proposing that people fulfill their occupational performance roles by engaging in routines, tasks and activities, in the domains of self-maintenance, productivity, leisure and rest, in the process responding to internal and/or external demands of the environment. This model assumes that engagement in occupations provides the sense of competence, autonomy, temporal organization, and meaning of existence to individuals. It focuses on activation of person-environment relationship through participation in occupations.
