- Translating clinical psychology research to practice could improve mental health care but it is challenging. Researchers often frame the problem in terms of uptake failure by clinicians. But are they doing clinically useful research? In press, American psychologist osf.io/preprints/ps...
- We asked clinicians what kind of research questions are most important to them, focusing on questions that could be addressed with between and within-person designs. For practice, within-person questions are at least as/more important
- We then reviewed six high impact journals in assessment, psychopathology, and psychotherapy. Between-person designs predominate.
