How to Practice Open Science: A Cookbook for Clinical Psychology and Psychotherapy Research

Even though Open Science practices advance the credibility and accessibility of knowledge gained through research, they are not yet as common in clinical psychology as in other subfields of psychology. This paper presents an overview of how to implement Open Science practices in clinical psychology and psychotherapy research. We will address frequently encountered challenges and present different ways to deal with sensitive topics within the specific field. We explain Open Science practices while planning a study, during data collection and preparation of a publication, and for the publication of results. Finally, we will show options for how to structure a whole research group in support of Open Science practices. With different types of actions - of varying degrees of complexity and openness - we can continually and ethically move toward more Open Science, which will strengthen clinical research and is therefore essential for people with lived experiences of psychological symptoms, patients, psychotherapists, and for investments in psychological treatments.
