Interventions in the Scope of Occupational Therapy to Improve Psychosocial Well-Being in Older Adults with Low Vision and Mental Health Concerns: A Systematic Review.

Research has found that occupational therapy practitioners focus on functional and participation outcomes in the low vision population, but overlook corresponding psychosocial outcomes in rehabilitation. The purpose of this systematic review is to answer the PICO question: "What is the evidence to support interventions within the scope of occupational therapy for improving psychosocial well-being or quality of life in adults experiencing depression or anxiety as a result of low vision?" The team conducted a search of literature published between 2008 and 2020. Inclusion criteria consisted of interventions within the scope of occupational therapy for patients with low vision, and which measured mental health or quality of life factors. Eleven articles met inclusion criteria. The majority of the evidence consisted of 1B (45%) and 2B (36%) level randomized control trials. Two studies were 3B level evidence. Mental health outcomes were measured primarily using depression rating scales, although a number of studies also utilized vision-specific quality of life questionnaires. Established intervention themes included behavioral activation plus occupational therapy low vision rehabilitation, cognitive problem-solving approaches, usual care 'plus' skill-based training, and group service delivery approaches. Moderate evidence supports behavioral activation plus occupational therapy low vision rehabilitation, problem-solving approaches, and group service delivery approaches for improving mental health outcomes. There is moderate evidence that does not support usual treatment 'plus' skill-based training to improve mental health.
