ABSTRACT
There exists little empirical evidence helping clinicians to select the most effective treatment for individual patients with persistent depressive disorder (PDD). This study identifies and characterizes subgroups of patients with PDD who are likely to benefit more from an acute treatment with psychotherapy than from pharmacotherapy and vice versa. Non-medicated outpatients with PDD were randomized to eight weeks of acute treatment with the Cognitive Behavioral Analysis System of Psychotherapy (CBASP; n = 29) or escitalopram plus clinical management (ESC/CM; n = 31). We combined several baseline variables to one composite moderator and identified two subgroups of patients: for 56.0%, ESC/CM was associated with a greater reduction in depression severity than CBASP, for the remaining 44.0%, it was the other way around. Patients likely to benefit more from ESC/CM were more often female, had higher rates of moderate-to-severe childhood trauma, more adverse life events and more previous suicide attempts. Patients likely to benefit more from CBASP were older, had more often an early illness onset and more previous treatments with antidepressants. Symptomatic response, remission, and reductions in symptom severity occurred more often in those patients treated with their likely more effective treatment condition. The findings suggest that the baseline phenotype of patients with PDD moderates their benefit from acute treatment with CBASP relative to ESC/CM. Once confirmed in an independent sample, these results could serve to guide the choice between primarily psychotherapeutic or pharmacological treatments for outpatients with PDD.

OBJECTIVES: A recent trial comparing Cognitive Behavioral Analysis System of Psychotherapy (CBASP) and supportive psychotherapy in chronic depression found CBASP to be more effective in treating depressive symptoms. We aimed to evaluate adverse events that occurred during this trial. MATERIALS AND METHOD: A randomized trial of chronically depressed outpatients was performed. The treatment included 32 sessions of CBASP or supportive psychotherapy. Therapists asked patients about adverse events and their intensity in each session using a standardized checklist. We analyzed the mean number of (severe) adverse events per patient up to Session 32 with gamma frailty recurrent event models. RESULTS: Two hundred and sixty patients were included in the analyses (66% female, mean age 45 years). Patients in the supportive psychotherapy group reported less severe adverse events in general, and less severe adverse events related to personal life and to occupational life than patients in the CBASP group. Less adverse events related to suicidal thoughts were reported in the CBASP compared with the supportive psychotherapy group. CONCLUSIONS: Differences in the adverse events profile may be explained by the treatment elements. Adverse events related to personal and occupational life for example might be considered a necessary and expected yet temporary adverse treatment outcome of an effective CBASP treatment.

BACKGROUND: Evidence on the long-term efficacy of psychotherapeutic approaches for chronic depression is scarce. OBJECTIVE: To evaluate the effects of the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) compared to Supportive Psychotherapy (SP) 1 year and 2 years after treatment termination. METHODS: In this study, we present 1- and 2-year follow-up assessments of a prospective, multicenter, evaluator-blinded, randomized clinical trial of outpatients with early-onset chronic major depression (n = 268). The initial treatment included 32 sessions of CBASP or SP over 48 weeks. The primary outcome was the rate of "well weeks" (Longitudinal Interval Follow-Up Evaluation; no/minimal symptoms) after 1 year and 2 years. The secondary outcomes were, among others, clinician- and self-rated depressive symptoms, response/remission rates, and quality of life. RESULTS: Of the 268 randomized patients, 207 (77%) participated in the follow-up. In the intention-to-treat analysis, there was no statistically significant difference between CBASP and SP patients in experiencing well weeks (CBASP: mean [SD] of 48.6 [36.9] weeks; SP: 39.0 [34.8]; rate ratio 1.26, 95% CI 0.99-1.59, p = 0.057, d = 0.18) and in remission rates (CBASP: 1 year 40%, 2 years 40.2%; SP: 1 year 28.9%, 2 years 33%) in the 2 years after treatment. Statistically significant effects were found in favor of CBASP 1 year after treatment termination regarding the rate of well weeks, self-rated depressive symptoms, and depression-related quality of life. CONCLUSIONS: CBASP lost its superiority over SP at some point between the first and the second year. This suggests the necessity of maintenance treatment for early-onset chronically depressed patients remitted with CBASP during the acute therapy phase, as well as the sequential integration of other treatment strategies, including medication for those who did not reach remission.

Childhood maltreatment (CM) has been indicated as a predictor of a differential response to antidepressant treatment with psychotherapy compared to medication. In this secondary analysis, we investigated whether the presence of CM results in a differential indication for the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) or escitalopram plus clinical management (ESC). Sixty patients with chronic depression were randomized to either 22 sessions of CBASP or ESC over the course of 8 weeks of acute and 20 weeks of extended treatment at 2 German treatment sites. CM was assessed using the Childhood Trauma Questionnaire and the clinician rated Early Trauma Inventory. Intention-to-treat analyses were used to examine the impact of CM on depression, global functioning, and quality of life. The presence of CM did not result in significant differences in treatment response to CBASP or ESC on any outcome measure after 28 weeks of treatment independent of the type of CM assessment. After 8 weeks, a significant CM × treatment interaction was found for scores on the Montgomery-Asberg Depression Rating Scale. Patients with a history of CM receiving CBASP had a significantly lower response rate compared to patients without CM and to those receiving ESC after 8 weeks. Conclusively, CBASP and ESC are equally effective treatment options for the difficult to treat subgroup of patients with chronic depression and a history of CM. CM may be a predictor of a longer latency of treatment response in the case of psychotherapy. KEY PRACTITIONER MESSAGE: CBASP and escitalopram are equally effective treatment options for chronic depression. Both treatments are also equally effective for the difficult to treat subgroup of patients with chronic depression and a history of childhood maltreatment. Childhood maltreatment may result in a longer latency of treatment response in the case of psychotherapy.

BACKGROUND: A specific psychotherapy for chronic depression, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), was compared to escitalopram (ESC). METHODS: Sixty patients with chronic major depression were randomized to 'CBASP' (22 sessions) or 'ESC plus clinical management' (ESC/CM) at two treatment sites. The primary outcome measure was the score on the Montgomery-Asberg Depression Rating Scale (MADRS) after 8 weeks of acute treatment assessed by blinded raters. In the case of nonimprovement (<20% reduction in the MADRS score), the other condition was augmented for the following 20 weeks of extended treatment. Secondary end points were, among others, depressive symptoms, remission (MADRS score of ≤9) and response rates (reduction of MADRS score of ≥50%) 28 weeks after randomization. RESULTS: An intent-to-treat analysis revealed that clinician-rated depression scores decreased significantly after 8 and 28 weeks with no significant differences between the groups. The response rates after 28 weeks of treatment were high (CBASP: 68.4%, ESC/CM: 60.0%), and the remission rates were moderate (CBASP: 36.8%, ESC/CM: 50.0%) with neither group being superior. Nonimprovers to the initial treatment caught up with the initial improvers in terms of depression scores and response and remission rates by the end of the treatment after being augmented with the respective other condition. CONCLUSIONS: CBASP and ESC/CM appear to be equally effective treatment options for chronically depressed outpatients. For nonimprovers to the initial treatment, it is efficacious to augment with medication in the case of nonresponse to CBASP and vice versa.

BACKGROUND: The only treatment specifically developed for chronic depression, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), is based amongst others on the hypothesis that chronically depressed patients (CD) show considerable deficits of affective theory of mind (ToM) capabilities. Data are scarce, however, and it remains unclear if ToM deficits are specific or if they arise from global cognitive deficits associated with depression. This study investigates the specific deficits of affective ToM abilities in CD. SAMPLING AND METHODS: ToM abilities were assessed in 26 medication-free CD and 26 matched healthy controls (HC) by means of a previously established false-belief ToM cartoon task. Since the task allowed an intern control for cognitive factors - operationalized in a visuospatial ToM task - it was possible to investigate specific affective ToM deficits. RESULTS: As hypothesized, the CD showed a significant specific slowdown of affective ToM compared to cognitive ToM (3rd person perspective) when compared to HC. Simultaneously, we observed a general deterioration of all ToM functions in CD. CONCLUSIONS: This study provides evidence that CD have a mentalization deficit, specifically for affective ToM functions. This deficit is combined with a general deterioration of ToM functions, most likely attributable to frequently described cognitive deficits in depression.

BACKGROUND: Effective treatment strategies for chronic depression are urgently needed since it is not only a common and particularly disabling disorder, but is also considered treatment resistant by most clinicians. There are only a few studies on chronic depression indicating that traditional psycho- and pharmacological interventions are not as effective as in acute, episodic depression. Current medications are no more effective than those introduced 50 years ago whereas the only psychotherapy developed specifically for the subgroup of chronic depression, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), faired well in one large trial. However, CBASP has never been directly compared to a non-specific control treatment. METHODS/DESIGN: The present article describes the study protocol of a multisite parallel-group randomized controlled trial in Germany. The purpose of the study is to estimate the efficacy of CBASP compared to supportive psychotherapy in 268 non-medicated early-onset chronically depressed outpatients. The intervention includes 20 weeks of acute treatment with 24 individual sessions followed by 28 weeks of continuation treatment with another 8 sessions. Depressive symptoms are evaluated 20 weeks after randomisation by means of the 24-item Hamilton Rating Scale of Depression (HRSD). Secondary endpoints are depressive symptoms after 12 and 48 weeks, and remission after 12, 20, and 48 weeks. Primary outcome will be analysed using analysis of covariance (ANCOVA) controlled for pre-treatment scores and site. Analyses of continuous secondary variables will be performed using linear mixed models. For remission rates, chi-squared tests and logistic regression will be applied. DISCUSSION: The study evaluates the comparative effects of a disorder-specific psychotherapy and a well designed non-specific psychological approach in the acute and continuation treatment phase in a large sample of early-onset chronically depressed patients. TRIAL REGISTRATION: ClinicalTrials.gov (NCT00970437).

BACKGROUND: Poor theory of mind (ToM) performance has been found in patients with mood disorders, but it has not been examined in the subgroup of chronic depression where ToM deficits may be even more persistent than in acute depressive episodes. The aim of this study was to compare the ToM performance of chronically depressed patients with a healthy control group and to clarify the relation of ToM to other cognitive functions. METHODS: ToM performance was assessed in 30 chronically depressed patients and 30 matched healthy controls by two cartoon picture story tests. In addition, logical memory, alertness, and executive functioning were evaluated. RESULTS: Chronically depressed patients were markedly impaired in all ToM- and neuropsychological tasks compared to healthy controls. Performance in the different ToM tests was significantly correlated with at least one other cognitive variable. After controlling for logical memory and working memory, no ToM tasks predicted being a patient. CONCLUSIONS: Patients with chronic depression present significant deficits in "reading" social interactions, which may be associated with general cognitive impairments.

BACKGROUND: Childhood maltreatment (CM) predicted poorer outcomes in acute depression treatment with CBT, IPT and Supportive Psychotherapy (SP). The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) fared well in patients with chronic depression and CM during acute treatment, yet there is a considerable lack of empirical evidence for long-term outcomes. METHODS: We analyzed one and two-year follow-up data of 268 patients randomized to 24 sessions (20 weeks) of acute and 8 sessions (28 weeks) of extended treatment with CBASP or SP. Primary outcome was the number of well weeks as measured by the Longitudinal Interval Follow-Up Evaluation Interview (LIFE). Secondary outcomes included self- and clinician-rated depression symptoms. We investigated this moderating effect for any CM and for specific subtypes of CM. RESULTS: Intent-to-treat analyses revealed that the presence of CM did not significantly moderate long-term effects of CBASP compared to SP. The analysis of trauma subtypes revealed that patients with childhood emotional abuse had statistically significant worse outcomes than patients without (main effect, p=.015) and that the advantage of CBASP over SP was larger in patients with childhood emotional abuse than in patients without (interaction effect, p=.045) after 1 year. No significant effects were found for other trauma subtypes. LIMITATIONS: The measurement of CM was limited to retrospective self-assessment. CONCLUSIONS: The presence of CM did not significantly moderate long-term treatment effects of CBASP compared to SP. When trauma subtypes were considered, CBASP was more effective than SP after one year in patients who retrospectively reported emotional abuse.

Importance: In the treatment of persistent depressive disorder (PDD), disorder-specific Cognitive Behavioral Analysis System of Psychotherapy (CBASP) has been shown to be superior to Supportive Psychotherapy (SP) in outpatients. It remains to clear which subgroups of patients benefit equally and differentially from both psychotherapies. Objective: To identify those patient-level baseline characteristics that predict a comparable treatment effectiveness of CBASP and SP and those that moderate the differential effectiveness of CBASP compared to SP. Design, setting and participants: In this analysis of a 48-week multicenter randomized clinical trial comparing CBASP to SP in adult antidepressant-free outpatients with early-onset PDD, we evaluated baseline variables from the following domains as potential predictors and moderators of treatment effectiveness: socio-demography, clinical status, psychosocial and global functioning, life quality, interpersonal problems, childhood trauma, treatment history, preference for psychotherapy, and treatment expectancy. Interventions: A 48-week treatment program with 32 sessions of either CBASP or SP. Main outcomes and measures: Depression severity measured by the 24-item Hamilton Rating Scale for Depression (HRSD-24) at week 48. Results: From N = 268 randomized outpatients, N = 209 completed the 48-week treatment program. CBASP completers had significantly lower post-treatment HRSD-24 scores than SP completers (meanCBASP=13.96, sdCBASP= 9.56; meanSP= 16.69, sdSP= 9.87; p = 0.04). A poor response to both therapies was predicted by higher baseline levels of clinician-rated depression, elevated suicidality, comorbid anxiety, lower social functioning, higher social inhibition, moderate-to-severe early emotional or sexual abuse, no preference for psychotherapy, and the history of at least one previous inpatient treatment. Moderator analyses revealed that patients with higher baseline levels of self-rated depression, comorbidity of at least one Axis-I disorder, self-reported moderate-to-severe early emotional or physical neglect, or at least one previous antidepressant treatment, had a significantly lower post-treatment depression severity with CBASP compared to SP (all p < 0.05). Conclusions and relevance: A complex multifactorial interaction between severe symptoms of depression, suicidality, and traumatic childhood experiences characterized by abuse, social inhibition, and anxiety may represent the basis of non-response to psychotherapy in patients with early onset PDD. Specific psychotherapy with CBASP might, however, be more effective and recommendable for a variety of particularly burdened patients compared to SP.
ABSTRACT
Does the pre-treatment profile of individuals with persistent depressive disorder (PDD) moderate their benefit from disorder-specific Cognitive Behavioral System of Psychotherapy (CBASP) versus supportive psychotherapy (SP)? We investigated this question by analyzing data from a multi-center randomized clinical trial comparing the effectiveness of 48 weeks of CBASP to SP in n â¯= â¯237 patients with early-onset PDD who were not taking antidepressant medication. We statistically developed an optimal composite moderator as a weighted combination of 13 preselected baseline variables and used it for identifying and characterizing subgroups for which CABSP may be preferable to SP or vice versa. We identified two distinct subgroups: 58.65% of the patients had a better treatment outcome with CBASP, while the remaining 41.35% had a better outcome with SP. At baseline, patients responding more favorably to CBASP were more severely depressed and more likely affected by moderate-to-severe childhood trauma including early emotional, physical, or sexual abuse, as well as emotional or physical neglect. In contrast, patients responding more favorably to SP had a higher pre-treatment global and social functioning level, a higher life quality and more often a recurrent illness pattern without complete remission between the episodes. These findings emphasize the relevance of considering pre-treatment characteristics when selecting between disorder-specific CBASP and SP for treating PDD. The practical implementation of this approach would advance personalized medicine for PDD by supporting mental health practitioners in their selection of the most effective psychotherapy for an individual patient.

BACKGROUND: Clinical guidelines recommend the combination of pharmaco- and psychotherapy for the treatment of chronic depression, although there are only a few studies supporting an additive effect of psychotherapy. METHODS: Forty-five inpatients with a chronic Major Depressive Disorder were randomized to 5 weeks of either Interpersonal Psychotherapy (IPT) modified for an inpatient setting (15 individual and 8 group sessions) plus pharmacotherapy or to medication plus Clinical Management (CM). The 17-item Hamilton Rating Scale for Depression was the primary outcome measure. The study included a prospective naturalistic follow-up, 3- and 12-months after discharge. RESULTS: Intent-to-treat analyses revealed a significantly greater reduction of depressive symptoms as well as better global functioning of patients treated with IPT compared to the CM group at week 5. Response and sustained response rates differed significantly between the two treatment conditions, favouring the IPT group. Remission rates were considerably higher for IPT patients who completed the treatment (67% vs. 32%). Patients who initially responded to IPT exhibited greater treatment gains at 12 months since only 7% of these subjects relapsed compared with 25% of the CM subjects. In the long-term, additional IPT led to a lower symptom level and higher global functioning. LIMITATIONS: The study uses data of a subset of patients from a larger trial. Both treatment groups did not receive comparable amounts of therapeutic attention. Extrapolating the data from this inpatient study to chronically depressed outpatients may not be possible. CONCLUSIONS: Intensive combined treatment provides superior acute and long-term effects over standard treatment in chronically depressed inpatients.

CM is increasingly used as a control condition in depression research. In the present study, the adherence of standardized CM sessions and their influence on outcome in depressed inpatients was investigated for the first time. In a randomized controlled trial, 43 inpatients with a diagnosis of Major Depression received medication treatment plus three-weekly CM sessions for 5 weeks. The 17-item version of the Hamilton Depression Rating Scale was the outcome measure. A total of 167 randomly selected audiotapes of CM sessions were evaluated using an adherence scale. The CM sessions delivered by psychiatric residents showed overall a high quality and included extensive support by the physician. The length of sessions was extended. The purity of sessions was associated with higher response rates. A diagnosis of Axis II-disorders or -traits and the clinical experience of the physician in years were predictors for less adherend treatments. However, both of them did not function as moderator variables.

OBJECTIVE: The purpose of this article was to determine the relative efficacy of a psychotherapy program when combined with pharmacotherapy versus medication and clinical management in more severely depressed patients. METHOD: A randomized controlled trial was conducted in 124 hospitalized patients with DSM-IV major depressive disorder that compared 5 weeks of interpersonal psychotherapy modified for depressed inpatients (15 individual and eight group sessions) plus pharmacotherapy with a regimen that involved medication plus intensive clinical management. The study included a prospective, naturalistic follow-up 3 and 12 months after acute treatment in 97 of 105 treatment completers. The 17-item version of the Hamilton Depression Rating Scale (HAM-D) was the primary outcome measure. RESULTS: For the intent-to-treat cohort (N=124), analysis of covariance (ANCOVA) showed that patients treated with interpersonal psychotherapy had a significantly greater reduction of depressive symptoms at week 5. Response rates differed significantly between the two treatment conditions, favoring the group that received adjuvant interpersonal psychotherapy (70%) versus clinical management (51%). Remission rates also tended to be higher for patients in the interpersonal psychotherapy group (49% versus 34%). Patients who initially responded to interpersonal psychotherapy exhibited greater treatment gains at the 3-month follow-up evaluation, since only 3% of these subjects relapsed, compared with 25% of the clinical management subjects. Nine months later, this difference lost statistical significance. CONCLUSIONS: An inpatient treatment program with both brief and intensive psychotherapy plus pharmacotherapy is superior to standard treatment. The results, which add to a growing body of evidence, suggest that this combination treatment may offer an advantage over treatment with medication and clinical management for more severely depressed patients.

IMPORTANCE: Chronic depression is a highly prevalent and disabling disorder. There is a recognized need to assess the value of long-term disorder-specific psychotherapy. OBJECTIVE: To evaluate the efficacy of the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) compared with that of nonspecific supportive psychotherapy (SP). DESIGN, SETTING, AND PARTICIPANTS: A prospective, multicenter, evaluator-blinded, randomized clinical trial was conducted among adult outpatients with early-onset chronic depression who were not taking antidepressant medication. Patients were recruited between March 5, 2010, and October 16, 2012; the last patient finished treatment on October 14, 2013. Data analysis was conducted from March 5, 2014, to October 27, 2016. INTERVENTIONS: The treatment included 24 sessions of CBASP or SP for 20 weeks in the acute phase, followed by 8 continuation sessions during the next 28 weeks. MAIN OUTCOMES AND MEASURES: The primary outcome was symptom severity after 20 weeks (blinded observer ratings) as assessed by the 24-item Hamilton Rating Scale for Depression (HRSD-24). Secondary outcomes were rates of response (reduction in HRSD-24 score of ≥50% from baseline) and remission (HRSD-24 score ≤8), as well as self-assessed ratings of depression, global functioning, and quality of life. RESULTS: Among 622 patients assessed for eligibility, 268 were randomized: 137 to CBASP (96 women [70.1%] and 41 men [29.9%]; mean [SD] age, 44.7 [12.1] years) and 131 to SP (81 women [61.8%] and 50 men [38.2%]; mean [SD] age, 45.2 [11.6] years). The mean (SD) baseline HRSD-24 scores of 27.15 (5.49) in the CBASP group and 27.05 (5.74) in the SP group improved to 17.19 (10.01) and 20.39 (9.65), respectively, after 20 weeks, with a significant adjusted mean difference of -2.51 (95% CI, -4.16 to -0.86; P = .003) and a Cohen d of 0.31 in favor of CBASP. After 48 weeks, the HRSD-24 mean (SD) scores were 14.00 (9.72) for CBASP and 16.49 (9.96) for SP, with an adjusted difference of -3.13 (95% CI, -5.01 to -1.25; P = .001) and a Cohen d of 0.39. Patients undergoing CBASP were more likely to reach response (48 of 124 [38.7%] vs 27 of 111 [24.3%]; adjusted odds ratio, 2.02; 95% CI, 1.09 to 3.73; P = .03) or remission (27 of 124 [21.8%] vs 14 of 111 [12.6%]; adjusted odds ratio, 3.55; 95% CI, 1.61 to 7.85; P = .002) after 20 weeks. Patients undergoing CBASP showed significant advantages in most other secondary outcomes. CONCLUSIONS AND RELEVANCE: Highly structured specific psychotherapy was moderately more effective than nonspecific therapy in outpatients with early-onset chronic depression who were not taking antidepressant medication. Adding an extended phase to acute psychotherapy seems promising in this population. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00970437.

OBJECTIVE: To capture any sleep quality changes associated with group psychotherapy. PATIENTS/METHODS: Physician-referred, chronically depressed patients (n = 25) were randomized to either eight group sessions of Mindfulness-based Cognitive Therapy (MBCT, n = 9) plus Treatment As Usual (TAU), or the Cognitive Behavioral Analysis System of Psychotherapy (CBASP, n = 8) plus TAU, or to TAU only (control group, n = 8). Participants recorded their sleep at home. The primary outcome variables were: stable and unstable sleep, which were assessed using cardiopulmonary coupling (CPC) analysis, and estimated total sleep and wake time (minutes). Cardiopulmonary coupling measures heart rate variability and the electrocardiogram's R-wave amplitude fluctuations associated with respiration. RESULTS: By post-treatment night 6, the CBASP group had more stable sleep (p= 0.044) and less wake (p = 0.004) compared with TAU, and less wake vs MBCT (p = 0.039). CONCLUSION: The CBASP group psychotherapy treatment improved sleep quality compared with Treatment As Usual.

Among multiple etiological factors of depressive disorders, childhood maltreatment (CM) gains increasing attention as it confers susceptibility for depression and predisposes to chronicity. CM assumedly inhibits social-cognitive development, entailing interactional problems as observed in chronic depression (CD), especially in affective theory of mind (ToM). However, the extent of CM among CD patients varies notably as does the severity of depressive symptoms. We tested whether the extent of CM or depressive symptoms correlates with affective ToM functions in CD patients. Regional brain activation measured by functional magnetic resonance imaging during an affective ToM task was tested for correlation with CM, assessed by the Childhood Trauma Questionnaire (CTQ), and symptom severity, assessed by the Montgomery-Åsberg Depression Rating Scale (MADRS), in 25 unmedicated CD patients (mean age 41.52, SD 11.13). Amygdala activation during affective ToM correlated positively with CTQ total scores, while (para)hippocampal response correlated negatively with MADRS scores. Our findings suggest that differential amygdala activation in affective ToM in CD is substantially modulated by previous CM and not by the pathophysiological equivalents of current depressive symptoms. This illustrates the amygdala's role in the mediation of CM effects. The negative correlation of differential (para)hippocampal activation and depressive symptom severity indicates reduced integration of interactional experiences during depressive states.
