Can we change our personality? By definition, personality is a static construct which implies a certain level of resistance to interventions that seek to promote change. Instead, researchers theorise that incremental changes in personality is facilitated through changes in related constructs such as cognition and motivation. A new meta analysis of existing personality change interventions sheds some light in the issue.
Original Research: A Systematic Review of Personality Trait Change Through Intervention
The current meta-analysis investigated the extent to which personality traits changed as a result of intervention, with the primary focus on clinical interventions. We identified 207 studies that had tracked changes in measures of personality traits during interventions, including true experiments and prepost change designs. Interventions were associated with marked changes in personality trait measures over an average time of 24 weeks (e.g., d .37). Additional analyses showed that the increases replicated across experimental and nonexperimental designs, for nonclinical interventions, and persisted in longitudinal follow-ups of samples beyond the course of intervention. Emotional stability was the primary trait domain showing changes as a result of therapy, followed by extraversion. The type of therapy employed was not strongly associated with the amount of change in personality traits. Patients presenting with anxiety disorders changed the most, and patients being treated for substance use changed the least. The relevance of the results for theory and social policy are discussed.
