In Chapter 9, “Psychoeducational and Social Support Interventions: Theory and Practice,” the history, theory, and application of both of these therapeutic approaches with caregivers and older adults are provided. While differences in structure and context exist, the underlying theoretical perspectives of these approaches are comparable, with goals and outcomes of enhanced coping, increased competence, and decreased stress. The chapter describes the use and practice of psychosocial education to increase knowledge, impart information, and foster skill development among older adults. Likewise, the methods employed in social support interventions to provide opportunities for older individuals to share experiences, foster connections with others in similar life circumstances, and enhance receipt of needed emotional and instrumental support are explained. Case studies demonstrating the use of both approaches with older care providers are included. Finally, the chapter outlines the range of environmental settings in which psychoeducational and social support interventions are commonly employed.
