Show moreBackground Only a minority of dialysis patients with depressive symptoms are diagnosed and receive treatment. Depressive symptoms are highly prevalent in this population and are associated with adverse clinical outcomes. Underlying factors for this undertreatment may be the lack of evidence for the safety and effectivity of antidepressant medication, the reluctance of patients to adhere to antidepressant medication, the lack of mental healthcare provision in somatic healthcare environments and end-stage renal disease (ESRD) related physical limitations that complicate face-to-face psychotherapy. Guided Internet-based self-help treatment has demonstrated to be effective for depressive symptoms in other chronic patient populations and may overcome these barriers. The aim of this study is to investigate the (cost) effectiveness of a guided Internet-based self-help intervention for symptoms of depression in dialysis patients. Methods This study is a cluster randomized controlled trial (RCT) that investigates the effectiveness of a 5-week Internet-based self-help Problem Solving Therapy (PST) for depressive symptoms in dialysis patients. Depressive symptoms will be measured using the Beck Depression Inventory - second edition (BDI-II), with a cut-off score of >= 10. We aim to include 206 dialysis patients with depressive symptoms who will be cluster randomized to the intervention or the Care as Usual (CAU) control group. Secondary outcomes will include anxiety symptoms, quality of life, economic costs and clinical outcomes, such as inflammatory factors and hair cortisol levels. Assessments will take place at baseline (T0), 2 weeks after intervention (T1) and 6 months (T2), 12 months (T3) and 18 months (T4) after intervention. The control group will be measured at the same time points. Analysis will be based on the intention-to-treat principle. Mixed models will be used to assess the changes within each condition between pre-treatment and post-treatment. Discussion If demonstrated to be (cost) effective, Internet-based PST will offer new possibilities to treat dialysis patients with depressive symptoms and to improve their quality of care. Show less

Show moreThis dissertation contains the results of an RCT into the effectiveness of an online self-help intervention for people living with HIV (PLWH) and depressive symptoms. Many PLWH suffer from depressive symptoms. Online interventions to treat depression may have benefits, such as less perceived stigma, a large reach and high accessibility. The online self-help intervention that we investigated is based on cognitive behavioral therapy and contains 4 components: stimulating activities, relaxation exercises, changing negative thoughts and goal attainment. Two meta-analyses were conducted and the results point to the effectiveness of psychosocial interventions for PLWH to improve depressive symptoms, anxiety symptoms, quality of life, psychological well-being, and medication adherence. The most important result of the RCT was that the intervention together with telephone coaching is effective in reducing depressive symptoms, compared to an attention-only control group. It was also found that the intervention may be effective for all PLWH, regardless of certain baseline characteristics. Furthermore, behavioral activation and goal reengagement were found to be mediators of the intervention effect. Also, the intervention is likely to be cost-effective compared to attention only. As eHealth interventions have benefits compared to face-to-face interventions, they should be more widely implemented in the mental healthcare for PLWH. Show less
