BACKGROUND Insufficient evidence exists for a viable choice between long- and short-term psychotherapies in the treatment of psychiatric disorders. The present trial compares the effectiveness of one long-term therapy and two short-term therapies in the treatment of mood and anxiety disorders. METHOD In the Helsinki Psychotherapy Study, 326 out-patients with mood (84.7%) or anxiety disorder (43.6%) were randomly assigned to three treatment groups (long-term psychodynamic psychotherapy, short-term psychodynamic psychotherapy, and solution-focused therapy) and were followed up for 3 years from start of treatment. Primary outcome measures were depressive symptoms measured by self-report Beck Depression Inventory (BDI) and observer-rated Hamilton Depression Rating Scale (HAMD), and anxiety symptoms measured by self-report Symptom Check List Anxiety Scale (SCL-90-Anx) and observer-rated Hamilton Anxiety Rating Scale (HAMA). RESULTS A statistically significant reduction of symptoms was noted for BDI (51%), HAMD (36%), SCL-90-Anx (41%) and HAMA (38%) during the 3-year follow-up. Short-term psychodynamic psychotherapy was more effective than long-term psychodynamic psychotherapy during the first year, showing 15-27% lower scores for the four outcome measures. During the second year of follow-up no significant differences were found between the short-term and long-term therapies, and after 3 years of follow-up long-term psychodynamic psychotherapy was more effective with 14-37% lower scores for the outcome variables. No statistically significant differences were found in the effectiveness of the short-term therapies. CONCLUSIONS Short-term therapies produce benefits more quickly than long-term psychodynamic psychotherapy but in the long run long-term psychodynamic psychotherapy is superior to short-term therapies. However, more research is needed to determine which patients should be given long-term psychotherapy for the treatment of mood or anxiety disorders.

BACKGROUND Psychotherapy is apparently an insufficient treatment for some patients with mood or anxiety disorder. In this study the effectiveness of short-term and long-term psychotherapies was compared with that of psychoanalysis. METHODS A total of 326 psychiatric outpatients with mood or anxiety disorder were randomly assigned to solution-focused therapy, short-term psychodynamic and long-term psychodynamic psychotherapies. Additionally, 41 patients suitable for psychoanalysis were included in the study. The patients were followed from the start of the treatment and assessed 9 times during a 5-year follow-up. The primary outcome measures on symptoms were the Beck Depression Inventory, the Hamilton Depression and Anxiety Rating Scales, and the Symptom Check List, anxiety scale. Primary work ability and functional capacity measures were the Work Ability Index, the Work-subscale of the Social Adjustment Scale, and the Perceived Psychological Functioning Scale. RESULTS A reduction in psychiatric symptoms and improvement in work ability and functional capacity was noted in all treatment groups during the 5-year follow-up. The short-term therapies were more effective than psychoanalysis during the first year, whereas the long-term therapy was more effective after 3years of follow-up. Psychoanalysis was most effective at the 5-year follow-up, which also marked the end of the psychoanalysis. CONCLUSIONS Psychotherapy gives faster benefits than psychoanalysis, but in the long run psychoanalysis seems to be more effective. Results from trials, among patients suitable for psychoanalysis and with longer follow-up, are needed before firm conclusions about the relative effectiveness of psychoanalysis and psychotherapy in the treatment of mood and anxiety disorders can be drawn.

Abstract Background: The information on whether long-term psychotherapy is superior in comparison with short-term therapies during a long time-perspective in the treatment of mood and anxiety disorder is incomplete. Aims: The present study addresses this question in a clinical trial with an exceptionally long follow-up. Methods: In the Helsinki Psychotherapy Study, 326 outpatients with mood or anxiety disorder were randomly assigned to long-term psychodynamic psychotherapy and two types of short-term psychotherapy (short-term psychodynamic psychotherapy and solution-focused therapy) and were followed up for 5 years from the start of treatment. The outcome measures were psychiatric symptoms measured by Beck Depression Inventory (BDI), Hamilton Depression Rating Scale (HDRS), Symptom Check List, anxiety scale (SCL-90-Anx), Hamilton Anxiety Rating Scale (HARS) and Symptom Check List, Global Severity Index (SCL-90-GSI), and working ability measured by the Work Ability Index (WAI), the Work-subscale (SAS-Work) of the Social Adjustment Scale (SAS-SR) and the Perceived Psychological Functioning Scale (PPF). Furthermore, remission variables based on changes in psychiatric symptoms and use of auxiliary treatment, were used. Results: After the 5-year follow-up, the rate of recovery from psychiatric symptoms and the work ability improvement rate remained higher in the long-term therapy group, whereas no differences in the effectiveness of the two short-term therapies of different modalities were found. Conclusions: Long-term psychotherapy is more effective than short-term therapy during a long follow-up, suggesting the need for a careful evaluation of suitability to short-term therapy. More research on the long-term effects of psychotherapy in large-scale studies is still needed, however.

BACKGROUND The need for treatment is, despite of its obvious usefulness, a scarcely used measure of effectiveness in psychotherapy trials. This study considers changes in the need for auxiliary psychiatric treatment after starting short- and long-term psychotherapy and psychoanalysis. METHODS Altogether 326 psychiatric outpatients with mood or anxiety disorder were randomly assigned to solution-focused therapy (SFT), short-term psychodynamic psychotherapy (SPP), or long-term psychodynamic psychotherapy (LPP) while 41 self-selected patients were allocated to psychoanalysis (PA). The patients were followed for 5 years from start of treatment. Outcome measures were use of auxiliary psychotherapy, psychotropic medication, and hospitalization for mental reasons. RESULTS About 60% of the patients used auxiliary treatment during the follow-up. It was most common in the short-term therapy groups and its incidence was highest during the first year after the start of therapy. The average numbers of all therapy sessions among patients starting the therapy were 60, 70, 240, and 670 in SFT, SPP, LPP, and PA, respectively, whereas the corresponding average numbers of study therapy sessions alone were 10, 19, 232, and 646. Over 50% of the patients receiving short-term therapy received on average 4-6 times more therapy sessions than initially assigned. LIMITATIONS Post-randomization withdrawal was uneven. CONCLUSIONS Auxiliary treatment is usual among patients receiving short- and long-term therapies, and apparently becomes common shortly after the start of treatment. Auxiliary treatment can be used as an outcome measure indicating the need for treatment, should be monitored clinically and considered when interpreting the results of effectiveness studies.

Outcomes of psychotherapy from the perspective of the users.

Jukka Valkonen; Vilma Hänninen; Olavi Lindfors

Abstract Psychotherapy is widely held to be an effective means to decrease depression. It seems, however, that not everyone benefits from every kind of therapy, and the relevant outcomes vary from person to person. In this article, the pre-therapy views and post-therapy experiences of 14 users of either long-term psychodynamic psychotherapy or short-term solution-focused therapy are analyzed. The interviewees’ personal views about their depression and therapy are approached with the concept of inner narrative. Three “basic stories” or orientations were found: life historical, situational and moral. These offered people different contexts from which to evaluate the outcomes of their therapy. The findings suggest that a persons expectations, hopes and values are worth taking into account to ensure positive therapy outcomes.

Vitamin D has been suggested to protect against depression, but epidemiological evidence is scarce. The present study investigated the relationship of serum 25-hydroxyvitamin D (25(OH)D) with the prevalence of depressive and anxiety disorders. The study population consisted of a representative sample of Finnish men and women aged 30-79 years from the Health 2000 Survey. The sample included 5371 individuals, of which 354 were diagnosed with depressive disorder and 222 with anxiety disorder. Serum 25(OH)D concentration was determined from frozen samples. In a cross-sectional study, a total of four indicators of depression and one indicator of anxiety were used as dependent variables. Serum 25(OH)D was the risk factor of interest, and logistic models used further included sociodemographic and lifestyle variables as well as indicators of metabolic health as confounding and/or effect-modifying factors. The population attributable fraction (PAF) was estimated. Individuals with higher serum 25(OH)D concentrations showed a reduced risk of depression. The relative odds between the highest and lowest quartiles was 0.65 (95% CI 0.46, 0.93; P for trend = 0.006) after adjustment for sociodemographic, lifestyle and metabolic factors. Higher serum 25(OH)D concentrations were associated with a lower prevalence of depressive disorder especially among men, younger, divorced and those who had an unhealthy lifestyle or suffered from the metabolic syndrome. The PAF was estimated to be 19% for depression when serum 25(OH)D concentration was at least 50 nmol/l. These results support the hypothesis that higher serum 25(OH)D concentrations protect against depression even after adjustment for a large number of sociodemographic, lifestyle and metabolic factors. Large-scale prospective studies are needed to confirm this finding.

The effectiveness of solution-focused therapy and short- and long-term psychodynamic psychotherapy on self-concept during a 3-year follow-up.

Olavi Lindfors; Paul Knekt; Esa Virtala; Maarit A. Laaksonen

Abstract This study compares the effectiveness of solution-focused therapy (SFT) and short- and long-term psychodynamic psychotherapy (SPP and LPP) on self-concept during a 3-year follow-up. Altogether, 326 patients with mood or anxiety disorder were randomized to SFT, SPP, and LPP in the Helsinki Psychotherapy Study. Outcome was assessed using the Structural Analysis of Social Behavior questionnaire at baseline and 7, 12, 24, and 36 months after. Overall, during the first year of follow-up, self-concept improved more in both SFT and SPP than in LPP, indicated by the primary outcome indicators self-directed affiliation (AF) and self-directed autonomy, as well as by most of the eight secondary cluster scores. After the 3-year follow-up, LPP was more effective than SFT in AF and in the cluster scores self-affirm, self-blame, and self-neglect, whereas no difference was noted between LPP and SPP. Long duration and psychodynamic orientation of therapy may be beneficial for self-concept improvement.

Social support as a predictor of the outcome of depressive and anxiety disorder in short-term and long-term psychotherapy

Olavi Lindfors; Sakari Ojanen; Tuija Jääskeläinen; Paul Knekt

Social support is known to be important for well-being of individuals, but it is not clear how it predicts psychotherapy outcome in patients suffering from depressive or anxiety disorders. The aim of the present study was to study the prediction of social support on the outcome of short-term and long-term psychotherapy. In the Helsinki Psychotherapy Study, 326 psychiatric outpatients, aged 20-46 years, and suffering from depressive or anxiety disorders, were randomly assigned to short-term psychotherapy (short-term psychodynamic or solution-focused) or long-term psychodynamic psychotherapy. The level of social support at baseline was assessed using the Brief Inventory of Social Support and Integration (BISSI). Psychiatric symptoms were assessed with the Symptom Check List, Global Severity Index (SCL-90-GSI) at baseline and four times during a 3-year follow-up. Patients with a high level of social support before treatment benefitted more from long-term than short-term therapy at the 3-year follow-up, whereas patients with a low level of social support experienced no such benefit. Pretreatment social support seems to predict differentially short- and long-term psychotherapy and thus needs to be acknowledged when evaluating patients resources and treatment options. More research is needed to verify these findings.

Self-concept and quality of object relations as predictors of outcome in short- and long-term psychotherapy

Olavi Lindfors; Paul Knekt; Erkki Heinonen; Esa Virtala

BACKGROUND Quality of object relations and self-concept reflect clinically relevant aspects of personality functioning, but their prediction as suitability factors for psychotherapies of different lengths has not been compared. This study compared their prediction on psychiatric symptoms and work ability in short- and long-term psychotherapy. METHODS Altogether 326 patients, 20-46 years of age, with mood and/or anxiety disorder, were randomized to short-term (solution-focused or short-term psychodynamic) psychotherapy and long-term psychodynamic psychotherapy. The Quality of Object Relations Scale (QORS) and the Structural Analysis of Social Behavior (SASB) self-concept questionnaire were measured at baseline, and their prediction on outcome during the 3-year follow-up was assessed by the Symptom Check List Global Severity Index and the Anxiety Scale, the Beck Depression Inventory and by the Work Ability Index, Social Adjustment Scale work subscale and the Perceived Psychological Functioning scale. RESULTS Negative self-concept strongly and self-controlling characteristics modestly predicted better 3-year outcomes in long-term therapy, after faster early gains in short-term therapy. Patients with a more positive or self-emancipating self-concept, or more mature object relations, experienced more extensive benefits after long-term psychotherapy. LIMITATIONS The importance of length vs. long-term therapy technique on the differences found is not known. CONCLUSIONS Patients with mild to moderate personality pathology, indicated by poor self-concept, seem to benefit more from long-term than short-term psychotherapy, in reducing risk of depression. Long-term therapy may also be indicated for patients with relatively good psychological functioning. More research is needed on the relative importance of these characteristics in comparison with other patient-related factors.

Psychological predictors on the outcome of short-term psychodynamic psychotherapy and solution-focused therapy in the treatment of mood and anxiety disorder.

Maarit A. Laaksonen; Paul Knekt; Laura Sares-Jäske; Olavi Lindfors

OBJECTIVE Patients pre-treatment suitability for short-term psychodynamic psychotherapy (STPP) and solution-focused therapy (SFT) has not been compared. The aim of this study was to compare the prediction of psychological suitability measures on outcome of STPP vs. SFT. METHOD Altogether 198 patients with mood or anxiety disorder were randomized to STPP or SFT. A 7-item Suitability for Psychotherapy Scale (SPS) was assessed at baseline and a cumulative SPS score was formed. Psychiatric symptoms were measured using SCL-90-GSI at baseline and seven times during a 3-year follow-up. RESULTS The SPS score predicted the outcome of both short-term psychotherapies; for patients with a good score short-term therapies seemed beneficial, whereas for patients with a poor score they did not seem sufficient. There was no difference between STPP and SFT in the prediction of the SPS score. CONCLUSIONS Psychological suitability measures may apparently be useful in the prediction of overall short-term psychotherapy outcomes.
