The concept of quality of life (QOL), as a psychosocial construct, process, measure, goal, and outcome, has gained much popularity in the rehabilitation literature during the past 35 years. As both a goal (i.e., assisting clients with chronic illnesses and disabilities (CIDs) to attain a better QOL) and a process-outcome indicator (i.e., assessing both subjective and objective levels of QOL during and following rehabilitation interventions), QOL has become one of the most prominent and central concepts in the field of rehabilitation. This chapter familiarizes the reader with the conceptual and temporal parallelism underlying the domains of community interventions and personal coping, of which rehabilitation services are an essential component, as part of their joint goal to improve QOL. It provides examples from the field of psychosocial rehabilitation, and more specific coping with CID, that address the temporal nature of QOL-improving coping strategies.
