<qa>  How many weeks will the manual be completed?Haemodialysis patients receiving dialysis through an NHS renal service will be invited to participate. To participate they will be consenting, over 18 years of age and experiencing depressive symptoms at a clinical level. Those eligible will be randomly assigned into one of two conditions; a control condition receiving treatment as usual TAU, and an intervention condition receiving TAU alongside an ACT self-help manual with weekly telephone support. The manual will be completed over six weeks. Both groups will be asked to complete questionnaires prior to intervention and 2 and 4 months post-intervention. Participants from each condition will be asked to participate in interviews to explore their experiences of taking part.
