- InterventionsPsychosocial intervention: Self-help cognitive based therapy, tailored for dialysis patients with build-in support from a psychotherapist. This treatment is based on a frequently used problem solving therapy. It is offered through both an e-health portal and on paper, depending on the preference of the patient. The intervention consists of 5 modules with explanatory texts and animations, exercises and weekly feedback from a trained psychotherapist.

Care-as-usual: Care as usual as provided by nephrologist, social workers and if applicable psychotherapists. This group will receive an online infomodule about depression in end-stage-renal-disease.
- Primary outcomeCluster randomized controlled trial of the intervention versus care as usual.
The primary outcome is the depression score, measured using the Beck Depression Inventory (BDI). The difference between T0 and T1 (1-2 weeks after treatment) is the primary outcome for clinical effectiveness. Care as usual will be compared with the intervention group.
- Secondary outcome BDI scores after 6, 12 and 18 months
Anxiety score, measured using the Beck Anxiety Inventory
Quality of life, measured using the SF-12
Inflammatory markers, cortisol and tryptophan to explore possible pathophysiological mechanisms
Explore the effect on morbidity (hospital admissions) and mortality
- TimepointsT0: Baseline (before randomization)
T1: Within 1-2 weeks after the intervention
T2: 6 months
T3: 12 months
T4: 18 months

- Brief summaryBackground:
Depressive symptoms are highly prevalent in dialysis patients and associated with adverse outcomes. However, depression is underdiagnosed and undertreated in this population. There is lack of robust randomized controlled trials relating to the effectiveness of therapeutic interventions. This study aims to investigate the effectiveness of an eHealth self-help intervention for depressive symptoms in dialysis patients. Furthermore, the biochemical changes and associations involved in depression in dialysis patients are examined.
This study can provide an accessible, patient friendly, low-cost intervention for the tr eatment of depressive symptoms and improving quality of life of dialysis patients.

Primary objective:
To deliver an easy accessible, patient friendly and low-cost self-help intervention for the treatment of depressive symptoms in dialysis patients.

Main hypothesis:
An eHealth CBT in tervention reduces depressive symptoms in dialysis patients.

Objective:
1. To investigate the effectiveness of a self-help CBT in lowering depressive symptoms and the associated adverse outcomes.
2. To examine the biochemical mechanisms involved in treating depression.
