 Acceptance and Commitment Therapy ACT has been found to be an effective treatment for depression and has been used successfully as a self-help treatment. However, no study has examined the effectiveness of an ACT self-help treatment for depression in ESRD. This study aims to assess the feasibility of conducting such a study and will look at suitability of recruitment, assessment methods and the acceptability of the self-help treatment, as well as helping to calculate the number of people needed for a definitive study.
