Results of a pilot randomised controlled trial to measure the clinical and cost effectiveness of peer support in increasing hope and quality of life in mental health patients discharged from hospital in the UK.

For both PS and CAU the mean rank scores reduce between T0 and T2, as participants become more hopeful, with a larger drop for those in the PS condition, although this fell short of significance χ 2(2) = 5.810, P = 0.055.

There were no significant differences between T0 and T1 scores (Z = −1.362, P = 0.173) or between T1 and T2 general health scores (Z = −1.826, P = 0.068) although the latter was approaching significance.
