RESUMEN
BACKGROUND: Problem-Solving Treatment (PST) has been used to treat and prevent depression in a variety of settings. However, the impact of PST on improving psychological well-being in those with recent vision loss remains unknown. The aim of this study was to evaluate whether PST may lead to better psychological well-being in people with recent vision loss through a pilot parallel-group randomised controlled trial. METHODS: Participants who were diagnosed with visual impairment during the previous 3 months were randomly allocated to either an 8-week PST or treatment as usual (N = 61). Outcome measures were administered at baseline, 3, 6, and 9-months. RESULTS: A linear mixed model demonstrated that PST significantly improved psychological well-being (measured by the Warwick Edinburgh Mental Well-being Scale) (treatment effect = 2.44; 95% CI = 0.40-4.47; p = 0.019). Significant improvements in the PST group for symptoms of distress, quality of life and self-efficacy were also observed. There was no significant difference in mobility. The treatment effect was consistent at all follow-ups. Attrition rate was low (13%). CONCLUSIONS: PST was associated with a significant and sustained improvement in a range of outcomes in people with recent vision loss. Further large scale RCT is now required.
RESUMEN
PURPOSE: For visually impaired individuals, motivation to be mobile and the individual's emotional states are predetermining factors of functioning. In addition, loss of confidence at the time of diagnosis could inhibit the ability to make progress. The aim of this study is to evaluate whether Problem-Solving Treatment, a brief, structured psychological intervention, leads to better psychological well-being in people who have been recently diagnosed as blind or partially sighted. METHODS: A pilot randomised controlled trial: the trial aims to recruit 120 individuals who have either: (1) been diagnosed with severe, irreversible sight loss, or (2) registered as blind or partially sighted within the last 3 months. Individuals will be randomly allocated to either the intervention or control group with randomisation stratified by severity of vision loss. Those in the intervention arm will receive Problem-Solving Treatment, an established intervention that addresses individual's confidence, motivation and psychological well-being by undertaking specific tasks to help individuals work through their problems, and recognising steps to problem resolution. Both groups will continue to receive routine care, such as mobility training. STUDY OUTCOMES: The primary outcome is psychological well-being measured at 3, 6, and 9 months after recruitment and assignment to intervention or control group. Secondary outcomes include symptoms of distress, mobility and quality of life.
