Study information
Scientific title
A randomised controlled trial comparing the impact of problem-solving treatment and usual care on wellbeing, functional mobility and quality of life of blind and partially sighted people
Acronym
Problem Solving Treatment in Visual Impairment (POSITIVE)
Study hypothesis
People who lose their vision can have a difficult time adjusting to their condition, especially in the early stages after their diagnosis. This can have an impact on their psychological well-being and their motivation and confidence to continue with their day-to-day activities. It is hoped that helping people to develop their problem-solving skills after their initial diagnosis will increase their level of confidence and wellbeing.
Once problem-solving skills are learnt, they can also be applied to a range of problems that individuals may encounter as a person living with vision loss. The aim of this study is to test an established intervention called Problem-Solving Treatment (PST) among 120 people with an early diagnosis of vision loss.

Intervention
A trial will be conducted where approximately half of participants will be randomly allocated to receive the intervention, and half will receive usual care. The intervention group will be split into those with severe and those with moderate to slight vision loss. The intervention consists of six sessions of Problem Solving Treatment conducted over 8 weeks, and also a telephone booster session approximately three months after the last session. The study will examine whether the intervention has a positive impact on psychological wellbeing, quality of life and mobility, and if any changes are related to severity of vision loss. If there is evidence that PST is a useful intervention for people with vision loss, the trialists will consider how it can be incorporated into usual care after diagnosis.
