'Optimal' participation: a reflective look.
PURPOSE: There is mounting interest by professionals working in the rehabilitation sciences related to the concept of participation, especially given the increasing numbers of individuals worldwide living with chronic illnesses. It is now internationally agreed that participation level is influenced by both personal and environmental factors. The question arises as to the meaning of 'optimal' participation. The main objective of this article is to provide a reflective look at the concept of participation and the meaning of 'optimality' for individuals with and without disability and to explore both in relation to response shift. METHOD: Similarities in definitions of participation are first examined. Normal participation level is discussed leading to an 'optimal' level based on normality. Cases are used to illustrate normality as well as how 'optimal' participation can be achieved through a transition period despite disabilities caused by a health condition such as a stroke. RESULTS: 'Optimal' participation would rely on a perfect fit between an individual's reality (how activities and roles are actually realised) and expectations of how activities and roles should be accomplished. A transition period, including a response shift, following an acute event or onset of a chronic condition can lead to an optimal participation level despite persisting disabilities. CONCLUSIONS: A better understanding of the meaning of optimal participation and its association to response shift is important to clinical practice. Interventions aimed at optimizing participation through assisting clients who are experiencing a response shift can then be designed to maximize participation and concomitantly, quality of life in those with chronic health conditions.
