Effectiveness of psychoanalysis and long-term psychodynamic psychotherapy on personality and social functioning 10 years after start of treatment

Abstract

The evidence on potentially greater benefits of psychoanalysis (PA) vs. long-term psychodynamic psychotherapy (LPP) is scarce. This study compared the effectiveness of PA and LPP on personality and social functioning during a 10-year follow-up from the beginning of the treatments. The eligible patients, 41 self-selected for PA and 128 assigned to LPP, were 20-45 years of age and had anxiety or mood disorder. Outcomes were analyzed using ten standard measures of personality and social functioning, carried out 5-9 times during the follow-up. Different change patterns by time in PA and LPP emerged, suggesting less benefit of PA during the first years of follow-up and more benefit in most outcomes thereafter. Greater post-treatment improvement in PA than in LPP was seen up to 1-2 years after PA had ended in more mature defense style (DSQ), level of personality organization (LPO), more positive self-concept (SASB), more improved social adjustment (SAS-SR) and sense of coherence (SOC). However, at the 10-year follow-up the differences were non-significant. In conclusion, PA may give some additional benefits when long-term aims are linked to personality and social functioning. The relatively small differences and higher costs in comparison to LPP may restrict the feasibility of PA.
