The Effectiveness of an Intensive Inpatient Psychotherapy Program for Chronic Depression: A naturalistic comparison with wait list.

BACKGROUND: Patients with chronic depression (CD) typically have an early symptom onset, more psychiatric comorbidities, more treatment attempts, and more frequent and longer inpatient hospitalizations than patients with major depressive disorders. The main purpose of this study was to investigate the effectiveness of an intensive inpatient psychotherapy program for patients with chronic depression (CD). The primary research question was whether two intensive psychodynamic inpatient treatments, affect phobia therapy (APT) and VITA, were superior to an outpatient wait list condition, receiving treatment as usual (TAU), at completion of treatment. To investigate if a potential difference between the intensive treatment and the wait list control group was dependent on a specific psychotherapeutic model, the study contrasted two therapies with similar intensity, but different theoretical rationales. METHODS: Two hundred eighty patients with CD were included in a naturalistic study. Patients were assessed at four time points; assessment, start of therapy, end of therapy and 1-year follow-up. Three comparisons were performed with patients matched across groups; Intensive inpatient treatment program (APT + VITA) vs wait list during treatment, APT vs VITA during treatment and APT vs VITA during follow-up. The outcome measure was the BDI-II. RESULTS: Intensive inpatient treatment program vs. wait list showed a significant difference in favor of the intensive treatment. No significant differences were found between APT and VITA during therapy or follow-up; but both groups had large effect sizes during treatment, which were maintained during follow-up. CONCLUSIONS: The intensive inpatient psychotherapy program showed superior effect on chronic depression over an outpatient wait list condition receiving treatment as usual (TAU), but no significant differences were found between the two intensive inpatient psychodynamic treatments. The results provide support for the effectiveness of an intensive inpatient psychotherapy program in treatment of chronic and severe disorders, such as CD, which could be of benefit for policymakers and the health care sector as they are allocating recourses efficiently. TRIAL REGISTRATION: This study has been retrospectively registered on ClinicalTrials.gov (NCT05221567) on February 3rd, 2022.

Trajectories of change in chronic depression: Differences in self-criticism and somatic symptoms between users of antidepressants and nonmedicated patients.

OBJECTIVE: Depression is typically seen as composed of several factors (i.e., cognitive, affective, somatic) which may be targeted by different interventions (i.e., pharmacotherapy, psychotherapy, or combination treatment). Successfully targeting these factors may contribute to improved treatment response in depression. A previous study identified two subfactors on Beck Depression Inventory-II (BDI-II) in a sample of chronically depressed patients: (a) self-criticism and (b) somatic symptoms (sleep disturbance, fatigue, changes in appetite). Prior research indicates that these symptoms may respond differently to psychotherapy and pharmacotherapy. In this study, we examined whether patients who were on antidepressant medication (ADM) had different outcomes on these factors than patients not using medication while undergoing intensive inpatient psychotherapeutic treatment. METHOD: After adjusting for baseline difference with propensity score matching, a total of 238 patients with chronic depression were included in the analysis of which 119 patients were using ADM during treatment while 119 were not. We analyzed whether the two groups had different trajectories of change on the factors "self-criticism" and "somatic symptoms" using multilevel growth curve modeling. RESULTS: Patients not using medication during treatment had significantly larger symptom reduction than ADM users on the self-criticism factor, while there was no difference between groups on the somatic factor. CONCLUSION: There seems to be a difference in outcomes on self-criticism depending on the use of ADM for this patient group. This may suggest that the simultaneous use of ADM while in psychotherapy could make patients less accessible to the effects of psychotherapeutic interventions on this factor.

Comparing outcomes in chronic depression following inpatient psychotherapy for patients continuing versus discontinuing antidepressant medication.

Research indicates that combination of psychotherapy and antidepressant medication (ADM) provides cumulative effects and thus outperforms monotherapy in treating chronic depression. In this quasi-experimental study, we explored symptom change for patients with chronic depression treated with ADM when presenting for a 12-week psychotherapeutic inpatient treatment programme. We compared outcomes through treatment and follow-up of patients who continued medication with those who discontinued. We also tested possible moderator effects of initial depression severity on change between the groups. Based on prior research, we hypothesized that combination treatment would yield better results (i.e., more reduction in depression). Patients (N = 112) were referred from general practitioners or local secondary health care. Outcome was measured by Beck Depression Inventory-II (BDI-II), and comparisons were carried out using multilevel modelling. Although 35 patients discontinued ADM during treatment, 77 continued. Both continuers and discontinuers had a significant treatment effect that was maintained at 1-year follow-up. There was no difference in outcome between continuers and discontinuers of ADM. Patients with severe depression had significantly more symptom improvement than patients with moderate depression, but depression severity did not affect outcomes across continuers and discontinuers of ADM differently. The results could indicate that patients had developed resistance and/or tolerance to the prophylactic effects of medication and that ADM did not contribute to the reduction of depressive symptoms. The findings may also indicate that psychotherapy alone in some instances can be a viable alternative to continued combined treatment. Clinicians should carefully assess benefits of patients' ongoing use of antidepressant medication when entering psychotherapy.

Self-compassion and fear of compassion in the treatment of chronic depression: Mechanisms of change?

OBJECTIVE: The aim of this naturalistic process study was to investigate the relationship between self-compassion, fear of compassion from others, and depressive symptoms over the course of psychotherapy in patients with chronic depression. METHOD: A sample of 226 patients with chronic depression who received inpatient short-term psychodynamic psychotherapy (STPP) provided weekly self-report measures of self-compassion, fear of compassion, and depressive symptoms (Patient Health Questionnaire-9). Trivariate latent curve modeling with structured residuals was applied to investigate the between- and within-patient relationships among the variables. RESULTS: At the between-patient level, a significant positive correlation was found between slope of depression and the slope of fear of compassion. At the within-patient level, a lower than expected level of fear of compassion predicted a subsequent lower than expected level of depression (mean weekly effect size = 0.12), with a smaller reciprocal relationship (mean weekly effect size = 0.08). There was no significant within-patient effect of self-compassion predicting subsequent depression, but a significant effect of a lower than expected level of depression predicting a subsequent higher than expected level of self-compassion (mean weekly effect size = -0.13). No within-patient effect between self-compassion and fear of compassion was found. CONCLUSIONS: In the context of this study, it appears that fear of compassion may be a putative mechanism of change involved in alleviating depressive symptoms in patients with chronic depression treated with STPP. On the other hand, self-compassion appears to be an outcome of psychotherapy. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Do self-criticism and somatic symptoms play a key role in chronic depression? Exploring the factor structure of Beck depression inventory-II in a sample of chronically depressed inpatients.

BACKGROUND: The factor structure of depression differs for different sub-samples. The purpose of this study was to explore the factor structure of Beck Depression Inventory-II in patients with chronic depression presenting for inpatient treatment. METHODS: Using exploratory structural equation modeling (ESEM), we explored whether a two-factor solution or a bifactor solution provided best model fit for a sample of 377 patients. For the best fitting model stability was assessed with tests for invariance across primary diagnosis (persistent depressive disorder v. recurrent major depressive disorder), and presence of comorbidity. RESULTS: A bifactor solution with one general factor and two specific factors provided best model fit. Invariance analyses provided support for measurement invariance and stability of the factor solution. LIMITATIONS: The naturalistic study design implies some uncertainty regarding possible systematic differences between the patients on demographic and clinical characteristics. CONCLUSION: The factor structure in our sample was best explained by a general depression factor, one specific factor pertaining to self-criticism, and one consisting of the somatic items fatigue, disturbance of sleep, and appetite. Clinicians could benefit from paying special attention to the subfactors identified, as these findings may have implications for treatment choice for patients with chronic depression.
