[Implementation of a Web-Based Self-Help Intervention for Mood Enhancement during Waiting Times for Outpatient Psychotherapy - A Qualitative Study Exploring Participants' Perspectives]. / Webbasierte Selbsthilfe zur Stimmungsverbesserung in der Wartezeit auf ambulante Psychotherapie ­ Eine qualitative Erhebung der Teilnehmerperspektive.

OBJECTIVE: In Germany, waiting times for outpatient psychotherapy are on average 5 months long. Guided web-based interventions can be implemented to reduce depressive symptoms during waiting times. The study aims to explore how patients experience the usage of a web-based intervention for mood enhancement. METHODS: Patients on the waiting lists of cooperating outpatient clinics were invited to participate in the study and apply a web-based intervention for mood enhancement. Eleven participating patients were interviewed about their experiences with the intervention. The data was analyzed based on the Grounded-Theory methodology. RESULTS: Three categories could be derived from the data: prior expectations, experiences with the intervention and factors influencing adherence. The web-based intervention was experienced very differently and was associated with both positive and negative experiences. The participants could be grouped into 3 user types. DISCUSSION: Not all patients report positive experiences with the intervention and some fail to adhere. In order to prepare patients adequately, they should be informed about the application and goals of the intervention in advance. Interventions should be implemented in accordance with the individual's need of support in order to enhance adherence and allow positive experiences.

Economic evaluations of internet- and mobile-based interventions for the treatment and prevention of depression: A systematic review.

BACKGROUND: Internet- and mobile-based interventions (IMIs) targeting depression have been shown to be clinically effective and are considered a cost-effective complement to established interventions. The aim of this review was to provide an overview of the evidence for the cost-effectiveness of IMIs for the treatment and prevention of depression. METHODS: A systematic database search was conducted (Medline, PsychInfo, CENTRAL, PSYNDEX, OHE HEED). Relevant articles were selected according to defined eligibility criteria. IMIs were classified as cost-effective if they were below a willingness-to-pay threshold (WTP) of €22,845 (£20,000) - €34,267 (£30,000) per additional quality-adjusted life year (QALY) according to the National Institute for Health and Clinical Excellence (NICE) standard. Study quality was assessed using the Consolidated Health Economic Evaluation Reporting Standard guidelines and the Cochrane Risk of Bias Tool. RESULTS: Of 1538 studies, seven economic evaluations of IMIs for the treatment of major depression, four for the treatment of subthreshold/minor depression and one for the prevention of depression. In six studies, IMIs were classified as likely to be cost-effective with an incremental cost-utility ratio between €3088 and €22,609. All of these IMIs were guided. Overall quality of most economic evaluations was evaluated as good. All studies showed some risk of bias. LIMITATIONS: The studies used different methodologies and showed some risk of bias. These aspects as well as the classification of cost-effectiveness according to the WTP proposed by NICE should be considered when interpreting the results. CONCLUSIONS: Results indicate that guided IMIs for the treatment of (subthreshold) depression have the potential to be a cost-effective complement to established interventions, but more methodologically sound studies are needed.
