Studies of educational methods for teaching psychiatric diagnostics to general practitioners and trainee general practitioners (RCTs, controlled before-and-after series or interrupted time series) and that included a change of behaviour as an outcome measure were eligible for inclusion. Studies that measured only change in knowledge and skills were excluded.
Included studies employed a wide variety of educational methods, most of which were poorly described by the primary studies. All except two of the included studies used a combination of educational methods. Educators who delivered interventions were varied and included psychiatrists, nurses and general practitioners. Duration of interventions varied widely, from single sessions (hours) to an extended education program over one year. It appeared that some studies that reported change in knowledge and skills outcomes were included. Twelve studies measured behavioural change using standardised patient measurements, video recordings or scored diagnoses. Seven studies measured patient outcome. Eight studies used self assessment.
Studies were independently screened for inclusion by two reviewers. Disagreements were resolved by the decision of a third reviewer.
