Childhood trauma and differential response to long-term psychoanalytic versus cognitive-behavioural therapy for chronic depression in adults

BACKGROUND

Childhood trauma is a major risk factor for chronic depression. It has been suggested that adults with chronic depression who have experienced childhood trauma may require long-term treatment owing to a breakdown of basic trust and related difficulties in developing a productive therapeutic relationship.

AIMS

As empirical studies have been preliminary and scarce, we studied the effects of psychoanalytic therapy (PAT) versus cognitive-behavioural therapy (CBT) for chronic depression in adults with a history of childhood trauma. In this subgroup, we expected a greater symptom reduction in PAT compared with CBT.

METHOD

In a large trial of long-term psychotherapies for chronic depression (LAC-Study; Clinical Trial Register ISRCTN91956346), 210 adults received open-ended CBT or PAT in an out-patient setting and were examined yearly over 5 years on the Beck Depression Inventory - II (BDI-II). Based on a linear mixed model approach, we tested participant-reported childhood trauma based on the Childhood Trauma Questionnaire (CTQ) as a predictor and moderator of treatment outcome. CTQ subscales were examined exploratively.

RESULTS

Depressive symptoms decreased over time (b = -4.55, s.e. = 0.90, 95% CI -6.32 to -2.81, T = -5.08; P < 0.001). A significant three-way interaction between childhood trauma, time and therapy group (b = -0.05, s.e. = 0.02, 95% CI -0.09 to -0.01, T = -2.42; P = 0.016) indicated that participants with childhood trauma profited especially well from PATs.

CONCLUSIONS

Our results indicate differential benefits from PAT compared with CBT among adults with chronic depression and a history of childhood trauma. The results have important implications for differential indication and policy.

The multi-level outcome study of psychoanalysis for chronically depressed patients with early trauma (MODE): rationale and design of an international multicenter randomized controlled trial

BACKGROUND

Whether and how psychotherapies change brain structure and function is unknown. Its study is of great importance for contemporary psychotherapy, as it may lead to discovery of neurobiological mechanisms that predict and mediate lasting changes in psychotherapy, particularly in severely mentally ill patients, such as those with chronic depression. Previous studies have shown that psychoanalytic psychotherapies produce robust and enduring improvements in not only symptom severity but also personality organization in patients who have chronic depression and early life trauma, especially if therapy is delivered at a high weekly frequency.

METHODS/DESIGN

Patients with chronic major depression and a history of early life trauma will be recruited, assessed, and treated across 3 international sites: Germany, Switzerland, and the United States. They will be randomized to one of two treatment arms: either (1) once weekly psychoanalytic psychotherapies, or (2) 3-4 times weekly psychoanalytic psychotherapies. They will have full clinical characterization as well as undergo MRI scanning at study baseline prior to randomization and again one year later. A group of matched healthy controls will undergo similar assessments and MRI scanning at the same time points to help discern whether study treatments induce brain changes toward or away from normal values. Primary study outcomes will include anatomical MRI, functional MRI, and Diffusion Tensor Imaging measures. Study hypotheses will be tested using the treatment-by-time interaction assessed in multiple general linear models with repeated measures analyses in an intent-to-treat analysis.

DISCUSSION

MODE may allow the identification of brain-based biomarkers that may be more sensitive than traditional behavioral and clinical measures in discriminating, predicting, and mediating treatment response. These findings could help to personalize care for patients who have chronic depression patients and early life trauma, and they will provide new therapeutic targets for both psychological and biological treatments for major depressive illness.

Recovery from chronic depression and structural change: 5-year outcomes after psychoanalytic and cognitive-behavioural long-term treatments (LAC depression study)

OBJECTIVE

Psychotherapy of chronic depression has remained a challenge due to limited prognosis and high rates of recurrence. We present 5-year outcome data from a multicentre trial comparing psychoanalytic (PAT) and cognitive-behavioural (CBT) long-term treatments with randomized and preferred allocations analysing symptom (N = 227) and structural change (N = 134) trajectories.

METHOD

Self- and blinded expert ratings of depression symptoms were performed at yearly intervals using the Beck Depression Inventory-II (BDI-II) and Quick Inventory of Depressive Symptoms (QIDS-C). Blinded expert ratings of Operationalized Psychodynamic Diagnosis (OPD) and the Heidelberg Restructuring Scale (HRS) at baseline, 1, 3, and 5 years assessed structural change in a subsample.

RESULTS

Lasting and comparable symptom changes were achieved by PAT and CBT. However, compared to CBT, PAT was more successful in restructuring, a major goal of long-term psychodynamic treatments with high frequency and duration.

LIMITATIONS

Due to practical reasons, the time criterion for chronic depression of an acute phase had to be defined for over 1 year in the present study, which does not correspond to the DSM-5 criterion of 2 years. Therapy duration and session frequency were not incorporated into the statistical models.

CONCLUSION

Long-term psychotherapy helps patients with a yearlong history of depression and often multiple unsuccessful treatment attempts to achieve lasting symptom changes. Future follow-up will clarify whether restructuring promotes further sustainable improvements.

How to measure sustained psychic transformations in long-term treatments of chronically depressed patients: Symptomatic and structural changes in the LAC Depression Study of the outcome of cognitive-behavioural and psychoanalytic long-term treatments

Worldwide, the pressure on psychoanalysis to prove the results of its treatments according to the criteria of so-called evidence-based medicine has increased. While a large number of studies on the results of psychoanalytic short-term therapies are now available, such studies are still largely lacking on psychoanalysis and psychoanalytic long-term therapies. In a large multicentre study, the results of psychoanalytical and cognitive-behavioural longterm therapies in chronically depressed patients were compared, Both psychotherapies led to statistically highly significant changes in depressive symptoms three years after the start of the treatments However, the focus of psychoanalytic treatments is not exclusively on reducing psychopathological symptoms, but on changes in the inner world of the patients that are reminiscent of the goal of psychoanalyses that Freud has characterized as developing "the ability to love, work and enjoy life." In the German-speaking community, such transformations are called "structural changes." This article reports results on such structural changes achieved with the help of a sophisticated measuring instrument, the Operationalized Psychodynamic Diagnostics (OPD). These so-called structural changes are compared with symptomatic changes. Three years after the start of the treatments, significantly more patients in psychoanalytical treatments show such structural changes than patients in cognitive-behavioural treatments.

The cognitive therapy of depression rests on substantial theoretical, empirical and clinical foundations: a reply to Dr Gipps

Dr Gipps claims that the cognitive therapy for depression rests on a mistake. But his anachronistic analysis of Beck's early research from the perspective of current psychoanalytic theory misses the point. The value of the research was not that it disproved psychoanalytic theory, but that it generated a model of depression that has revolutionised psychotherapy research. Psychoanalysts are belatedly adopting research methods that Beck pioneered half a century ago. The cognitive model of depression has explanatory power for both maintenance and vulnerability and has substantial research underpinning it. Cognitive therapy for depression has a larger body of evidence for its efficacy and relapse prevention effect than any other psychotherapy. Transference-focused approaches to depression have yet to establish themselves in the same way.

Pragmatic randomized controlled trial of long-term psychoanalytic psychotherapy for treatment-resistant depression: the Tavistock Adult Depression Study (TADS)

This pragmatic randomized controlled trial tested the effectiveness of long-term psychoanalytic psychotherapy (LTPP) as an adjunct to treatment-as-usual according to UK national guidelines (TAU), compared to TAU alone, in patients with long-standing major depression who had failed at least two different treatments and were considered to have treatment-resistant depression. Patients (N=129) were recruited from primary care and randomly allocated to the two treatment conditions. They were assessed at 6-monthly intervals during the 18 months of treatment and at 24, 30 and 42 months during follow-up. The primary outcome measure was the 17-item version of the Hamilton Depression Rating Scale (HDRS-17), with complete remission defined as a HDRS-17 score ≤8, and partial remission defined as a HDRS-17 score ≤12. Secondary outcome measures included self-reported depression as assessed by the Beck Depression Inventory - II, social functioning as evaluated by the Global Assessment of Functioning, subjective wellbeing as rated by the Clinical Outcomes in Routine Evaluation - Outcome Measure, and satisfaction with general activities as assessed by the Quality of Life Enjoyment and Satisfaction Questionnaire. Complete remission was infrequent in both groups at the end of treatment (9.4% in the LTPP group vs. 6.5% in the control group) as well as at 42-month follow-up (14.9% vs. 4.4%). Partial remission was not significantly more likely in the LTPP than in the control group at the end of treatment (32.1% vs. 23.9%, p=0.37), but significant differences emerged during follow-up (24 months: 38.8% vs. 19.2%, p=0.03; 30 months: 34.7% vs. 12.2%, p=0.008; 42 months: 30.0% vs. 4.4%, p=0.001). Both observer-based and self-reported depression scores showed steeper declines in the LTPP group, alongside greater improvements on measures of social adjustment. These data suggest that LTPP can be useful in improving the long-term outcome of treatment-resistant depression. End-of-treatment evaluations or short follow-ups may miss the emergence of delayed therapeutic benefit.
