Background
Laypeople tend to misunderstand that biological processes underlying mental disorders are largely uncontrollable with human effort. In contrast, psychotherapy is believed to require individual effort and is therefore seen as incompatible with addressing biological processes. This study examined whether explaining how some biological processes are controllable and malleable can remove distrust of psychotherapy when depression is attributed to biological factors.
Methods
Participants from the general public (n = 898) and individuals with symptoms of depression (n = 672) rated the effectiveness of psychotherapy for depression before and after learning about biological causes of a depression case. In the biology-controllability condition, participants learned how psychotherapy helps people control biological processes underlying depression. In the psychotherapy-controllability condition, they learned how psychotherapy teaches control over depressive symptoms, rather than biological processes.
Results
Unlike the control condition, participants in the biology-controllability and psychotherapy-controllability conditions judged psychotherapy as significantly more effective, and this increase was greater in the biology-controllability condition than in the psychotherapy-controllability condition.
Conclusions
An intervention specifically counteracting the belief that biological processes are uncontrollable can best mitigate distrust of psychotherapy for biologically attributed depression.
