The effectiveness of short- and long-term psychotherapy on personality functioning during a 5-year follow-up

Changes in interpersonal problems in the psychotherapeutic treatment of depression as measured by the Inventory of Interpersonal Problems: A systematic review and meta-analysis

“…There were not considered suitable for a metaanalysis due to the large variations in treatment length (3-60 months) and follow-up period (1-5 years). However, four of these studies demonstrated a small continued improvement in IIP total score between end of treatment and the follow-up assessment: 1 year post end of a brief Intensive Short-Term Dynamic Program (ISTDP), d=0.22 (Solbakken and Abbass 2015); 1 year post long-term Psychoanalytic Psychotherapy (PP), d=0.17 (Salzer et al 2010); 3 years post long-term PP, Psychodynamic Psychotherapy (PD) or CBT, d=0.22 (Zimmermann et al 2015; 5 years post start of treatment with Solution-Focused Therapy (SFT), STPP or Long-Term Psychodynamic Psychotherapy (LTPP), d=0.16, 0.51 and 0.14, respectively (Lindfors et al 2015).…”

Patterns of Change in Interpersonal Problems During and After Short-term and Long-term Psychodynamic Group Therapy: A Randomized Clinical Trial

“…Self-neglect). The long-term format also showed better results than the short-term psychodynamic format, as the 5-year data supported the superiority of long-term therapy Lindfors et al, 2015). They also found that a lower initial values of Affiliation and Autonomy were predictors of better effect, and patients improved more after long-term therapy compared to short-term therapies on both symptoms and work ability (Lindfors Knekt, Heinonen, & Virtala, 2014).…”

“…The effectiveness of two short-term individual psychotherapies (solution-focused, less than 12 sessions, and shortterm psychodynamic, 20 sessions) and one long-term psychodynamic therapy (mean duration 31 months) were compared in a study of outpatients (n=326) with anxiety and mood disorders (18% of the patients had a PD). At 5-year follow-up, the authors found that long-term therapy improved personality functioning more than did short-term therapies (Lindfors et al, 2015). To our knowledge, the only randomized trial which compared IIP subscale changes in group psychotherapy was performed by Tasca and colleagues (2012).…”

“…However, most support for these assumptions comes from observational studies of individual therapy (e.g., Kopta, Howard, Lowry, & Beutler, 1994;Barkham, Rees, Stiles, Hardy, & Shapiro, 2002;Haase et al, 2008;Howard, Lueger, Maling, & Martinovich, 1993;Leichsenring, Biskup, Kreische, & Staats, 2005). It is therefore particularly relevant to measure these aspects experimentally, for example by comparing the effectiveness of short-term and long-term therapies within the same study (Lindfors, Knekt, Heinonen, Härkänen, & Virtala, 2015).…”
