Study type
Description of intervention(s) / exposure
Problem solving treatment for primary care (PST-PC) is a manual driven psychological treatment that teaches problem-solving skills. It aims to help people with vision loss find practical solutions to vision-related problems, reduce avoidance behaviours and adopt a positive problem solving orientation. PST-PC will be delivered by PST specialists in eight weekly telephone sessions (30-45mins duration). Following the acute treatment sessions, monthly maintenance sessions with clients will be held over the phone (30-40mins duration) for 10 months following the acute treatment sessions.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All interviews will be conducted over the phone by trained research assistants using a computer-assisted interview. Baseline interviews will be collected prior to randomization. Following the baseline assessment, participants will be allocated to the intervention or control groups based on the code contained within the next sequential sealed envelope. Follow-up interviews will be conducted by research staff masked to participant allocation. Breaches of masking will be assessed and reasons obtained.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Brief summary
Depression is very common in people with vision impairment and can lead to heightened levels of disability and functional decline. However only a minority of people with vision impairment gain access to psychological support services. Together with Vision Australia and beyondblue we will examine the impact of different depression management options for people with vision loss.
