Design: Current summative evaluation study follows a naturalistic one-group pretest–posttest design and assesses three distinct stakeholders: patients, mental healthcare professionals, and mental healthcare organisa- tions. The Model for Assessment of Telemedicine applications (MAST) will be employed to structure the imple- mentation and evaluation study. The primary focal points of interest are reach, clinical effect, acceptability,appropriateness, implementation costs, and sustainability of the interventions in practice. Mixed-methods are used to provide an understanding of what (quantitative) the implementation projects have achieved and their meaning to various stakeholders (qualitative).
Discussion: The use of Internet interventions in routine practice is limited. MasterMind attempts to bridge the gap between routine practice and effectiveness research by evaluating the implementation of evidence-based Inter- net interventions for depressive disorders in routine mental healthcare settings in Europe.
