Brief Summary:
The goal of this clinical trial is to test in three samples including sample 1 lay people without reported depression symptoms sample 2 lay people with reported depression symptoms and sample 3 mental health clinicians The main questions it aims to answer are 1 do each of these populations show a bias against psychotherapy wherein they judge psychotherapy to be less effective relative to baseline ratings when a mental illness ie depression is attributed to biological factors 2 whether an intervention emphasizing the neurobiological effects of psychotherapy can remove this bias against psychotherapy for biologically-caused mental disorders and 3 whether this intervention is more effective compared to an active control intervention that emphasizes the effectiveness of psychotherapy but not its neurobiological effects Participants will
rate the effectiveness of psychotherapy for depression before and after learning about the biological causes of depression
be assigned to one of three conditions 1 an intervention condition where participants will receive a brief reading passage approximately 126 words in length providing psychoeducation about how psychotherapy changes the brain of an individual with depression or 2 an active control condition where participants will receive a reading passage approximately 115 words emphasizing the effectiveness of psychotherapy or 3 a control condition where they will receive no additional materials
as a secondary outcome participants will also rate the effectiveness of medication for depression before and after learning about the biological causes of depression

Detailed Description:
Overview Previous studies showed that biological explanations for mental disorders which are popularizing cause laypeople and clinicians to judge that psychotherapy is less effective This could be clinically detrimental as the combination of pharmacotherapy and psychotherapy is often optimal Objective This study tests a de-biasing intervention developed to counteract the flawed dualistic belief that activities perceived as occurring in the mind eg psychotherapy do not necessarily affect the brain Design Setting Participants This survey was conducted between September 10 2020 and April 2 2022 through Qualtricscom over laypeople with and without symptoms of depression and licensed clinicians in the US Participants were randomly assigned to either an intervention condition explaining how psychotherapy results in brain-level changes an active control condition explaining the effectiveness of psychotherapy but not its biological mechanisms or a control condition with no intervention Main Outcome Measures Participants rated the efficacy of psychotherapy for biologically caused depression before and after being assigned to one of the three conditions It was hypothesized that the dualism intervention would increase ratings of the effectiveness of psychotherapy even after participants learned about the biological causes of depression It was also expected that this intervention would increase psychotherapy ratings more than the active control materials that also emphasized the effectiveness of psychotherapy
