RESUMEN

ABSTRACT: In a recent randomized controlled trial of mild to moderate depression, hypnotherapy (HT) was noninferior to cognitive behavioral therapy (CBT) after 6 months of outpatient treatment. In the present article, we extended the results in a secondary analysis and investigated how HT compares with CBT 1) during the course of the self-rated depressive symptoms throughout the 12-month follow-ups, 2) with regard to the rates of full remission, and 3) for the time to remission after treatment. Of the 152 randomized patients with current depression, 136 were available for the follow-up analyses. The course of self-rated depressive symptoms during follow-ups was analyzed with linear mixed-effects models. Time to a full remission, defined as eight consecutive weeks without depression, was compared between groups in a survival analysis. The self-reported depressive symptoms could be maintained on a low symptom level during the 12-month follow-up for both HT and CBT. Overall, both treatments achieved comparably high long-term remission rates of 73% after a median of 30 weeks. Outpatient psychotherapy with HT achieved good long-term results mostly comparable to CBT.

RESUMEN

OBJECTIVE: The scientific approval of hypnotherapy for certain mental disorders is still not confirmed. In a randomized-controlled study comparing the efficacy of hypnotherapy (HT) with cognitive behavioral therapy (CBT) for mild to moderate depressive episodes, a non-inferiority of HT compared to CBT could be found. The aim of this study was to examine depressive symptomatology in the long-term course three and a half years after end of the treatment. METHODS: A total of 152 randomized patients received outpatient individual psychotherapy with 16 to 20 sessions over a period of six months. All were invited to participate in a follow-up three and a half years after the end of treatment where depressive symptoms were assessed via self- and clinician-ratings. In the per-protocol (PP) analysis, only those with available data were included, but a comparison of characteristics was made with individuals without participation in the follow-up survey. An additional intention-to-treat (ITT) analysis was conducted with multiple imputed data for missing data. RESULTS: A total of 71 subjects (46.7%) participated in the follow-up. The noninferiority in the percentage symptom reduction assessed with the clinician-rating of HT compared with CBT was confirmed in the PP and the ITT sample. The symptom improvement in self- and clinician-rating by the end of therapy persisted during the follow-up. Response rates and remission rates for both self- and clinician-ratings are reported. CONCLUSION: In this study, indications were found that HT was noninferior to CBT in the treatment of depression, even in the long term. Further studies should examine the efficacy of HT in larger multicenter samples and identify predictors of individual treatment success.

RESUMEN

Hypnotherapy (HT) is a promising approach to treating depression, but so far, no data are available on the neuronal mechanisms of functional reorganization after HT for depressed patients. Here, 75 patients with mild to moderate depression, who received either HT or Cognitive Behavioral Therapy (CBT), were measured before and after therapy using functional near-infrared spectroscopy. We investigated the patients' cerebral activation during an emotional human gait paradigm. Further, rumination was included as predictor. Our results showed a decrease of functional connectivity (FC) between two regions that are crucial to emotional processing, the Extrastriate Body Area (EBA) and the Superior Temporal Sulcus (STS). This FC decrease was traced back to an activation change throughout therapy in the right STS, not the EBA and was only found in the HT group, depending on rumination: less ruminating HT patients showed a decrease in right STS activation, while highly ruminating patients showed an increase. We carefully propose that this activation change is due to the promotion of emotional experiences during HT, while in CBT a focus lay on activating behavior and changing negative cognitions. HT seemed to have had differential effects on the patients, depending on their rumination style: The increase of right STS activation in highly ruminating patients might mirror the improvement of impaired emotional processing, whilst the decrease of activation in low ruminating patients might reflect a dismissal of an over-compensation, associated with a hyperactivity before therapy. We conclude that HT affects emotional processing and this effect is moderated by rumination.

RESUMEN

To date, only few studies have attempted to investigate non-ignorable dropout during Internet-based interventions by applying an NMAR model, which includes missing data indicators in its equations. Here, the Muthen-Roy model was used to investigate change and dropout patterns in a sample of patients with mild-to-moderate depression symptoms (N = 483) who were randomized to a 12-week Internet-based intervention (deprexis, identifier: NCT01636752). Participants completed the PHQ-9 biweekly during the treatment. We identified four change-dropout patterns: Participants showing high impairment, improvement and low dropout probability (C3, N = 134) had the highest rate of reliable change at 6- and 12-month follow-up. A further pattern was characterized by high impairment, deterioration and high dropout probability (C2, N = 32), another by low impairment, improvement and high dropout probability (C1, N = 198). The last pattern was characterized by high impairment, no change and low dropout probability (C4, N = 119). In addition to deterioration, also rapid improvement may lead to dropout as a result of a perceived "good enough" dosage of treatment. This knowledge may strengthen sensitivity for the mechanisms of dropout and help to consider its meaning in efforts to optimize treatment selection.

RESUMEN

INTRODUCTION: Numerous studies prove the efficacy of internet-based self-help programs, but integration into the health-care system was rarely investigated. The present study addresses the implementation of an internet-based self-help program into routine care of patients with depressive symptoms waiting for psychotherapy at the university outpatient center. MATERIAL AND METHODS: Patients waiting for outpatient psychotherapy were randomly assigned to either a control group or an intervention group that received access to the internet-based program Deprexis during the waiting period. Depressive symptoms were assessed before and after waiting. Additionally, expectations and program use of participants were exploratively examined. RESULTS: Only half of the patients who were informed about the study were interested in participation. Participants used about half of the modules in the program Deprexis. Depressive symptoms were reduced in both groups during the waiting time. However, the symptom improvements were not significant. DISCUSSION: Integration of internet-based self-help programs into the German health-care system should include support by a psychotherapist. Preferences of participants should also be considered to enhance adherence and efficacy of the program. CONCLUSION: Internet-based self-help programs for use in the waiting time for outpatient psychotherapy of patients with depression should involve guidance.

RESUMEN

Digital media, online programs, and electronic health systems are available and easily accessible for diagnostic, prevention, and intervention of somatic and psychiatric disorders. These modern tools can assess objective as well as subjective information about acute symptoms, wellbeing, life quality, sleep, physiological indicators, etc. Wearables and apps collect data over days and weeks in the real world of subjects. This information can be used to document baselines as well as changes over time influenced by events or interventions. Online treatment programs provide information for education about symptoms, course, origin, and treatment options of a disorder. They also support a patient's self-help via self-management, exercises, and techniques. We illustrate and discuss modern diagnostic and therapeutic eHealth options. We also review the empirical evidence for online interventions and refer to typical examples. Most studies have been conducted with subjects suffering from depression and anxiety. Electronic health systems do not work just by recommending a program or providing access to an online platform. Patients need to be motivated to lock in and work with a program. They need support and guidance through online programs. Therefore, we claim that therapists need to become experts in digital media and electronic health systems to support patients and to integrate apps and online programs into their treatment.

RESUMEN

BACKGROUND: Web-based interventions for individuals with depressive disorders have been a recent focus of research and may be an effective adjunct to face-to-face psychotherapy or pharmacological treatment. OBJECTIVE: The aim of our study was to examine the early change patterns in Web-based interventions to identify differential effects. METHODS: We applied piecewise growth mixture modeling (PGMM) to identify different latent classes of early change in individuals with mild-to-moderate depression (n=409) who underwent a CBT-based web intervention for depression. RESULTS: Overall, three latent classes were identified (N=409): Two early response classes (n=158, n=185) and one early deterioration class (n=66). Latent classes differed in terms of outcome (P<.001) and adherence (P=.03) in regard to the number of modules (number of modules with a duration of at least 10 minutes) and the number of assessments (P<.001), but not in regard to the overall amount of time using the system. Class membership significantly improved outcome prediction by 24.8% over patient intake characteristics (P<.001) and significantly added to the prediction of adherence (P=.04). CONCLUSIONS: These findings suggest that in Web-based interventions outcome and adherence can be predicted by patterns of early change, which can inform treatment decisions and potentially help optimize the allocation of scarce clinical resources.

RESUMEN

BACKGROUND: Mild to moderate depressive symptoms are common but often remain unrecognized and treated inadequately. We hypothesized that an Internet intervention in addition to usual care is superior to care as usual alone (CAU) in the treatment of mild to moderate depressive symptoms in adults. METHODS: This trial was controlled, randomized and assessor-blinded. Participants with mild to moderate depressive symptoms (Patient Health Questionnaire, PHQ-9, score 5-14) were recruited from clinical and non-clinical settings and randomized to either CAU or a 12-week Internet intervention (Deprexis) adjunctive to usual care. Outcomes were assessed at baseline, 3 months (post-assessment) and 6 months (follow-up). The primary outcome measure was self-rated depression severity (PHQ-9). The main analysis was based on the intention-to-treat principle and used linear mixed models. RESULTS: A total of 1,013 participants were randomized. Changes in PHQ-9 from baseline differed signixFB01;cantly between groups (t825 = 6.12, p < 0.001 for the main effect of group). The post-assessment between-group effect size in favour of the intervention was d = 0.39 (95% CI: 0.13-0.64). It was stable at follow-up, with d = 0.32 (95% CI: 0.06-0.69). The rate of participants experiencing at least minimally clinically important PHQ-9 change at the post-assessment was higher in the intervention group (35.6 vs. 20.2%) with a number needed to treat of 7 (95% CI: 5-10). CONCLUSIONS: The Internet intervention examined in this trial was superior to CAU alone in reducing mild to moderate depressive symptoms. The magnitude of the effect is clinically important and has public health implications.

RESUMEN

With the development of the Behavioral Activation for Depression Scale (BADS) by Kanter, et al. [1], different behavioral aspects of depression like activation, rumination or avoidance, and functional impairment can be measured. The long and the short versions of the BADS, however, show differences in the quality of psychometric properties. We wanted to validate the short and long forms of the BADS. We therefore evaluated the factor structure, the psychometric properties, and the construct validity of the long version and the subscales in a clinically depressed German sample (n=258) in study 1. In study 2, we explored the factor structure and the psychometric properties of the short version of the BADS in a subsyndromal sample with elevated depressive symptoms (n=406). In study 1, our results replicated the four factor solution of the BADS-25 original version and showed good psychometric properties. However, with regard to the BADS-9 only the French factor solution of the short BADS-9 demonstrated acceptable fit with low internal consistency of the subscale Avoidance. Thus, only the total score of the short form can be recommended.

RESUMEN

Worldwide, more than eight million people die each year as a result of tobacco use. A large proportion of smokers who want to quit are interested in alternative smoking cessation methods, of which hypnotherapy is the most popular. However, the efficacy of hypnotherapy as a tobacco cessation intervention cannot be considered sufficiently proven due to significant methodological limitations in the studies available to date. The aim of the present study was to compare the efficacy of a hypnotherapeutic group program for smoking cessation with that of an established cognitive-behavioral group program in a randomized controlled trial. A total of 360 smokers who were willing to quit were randomly assigned to either hypnotherapy (HT) or cognitive-behavioral therapy (CBT) at two study sites, without regard to treatment preference. They each underwent a 6 weeks smoking cessation course (one 90 min group session per week) and were followed up at regular intervals over a 12 months period. The primary outcome variable was defined as continuous abstinence from smoking according to the Russell standard, verified by a carbon monoxide measurement at three measurement time points. Secondary outcome variables were 7 days point prevalence abstinence during the 12 months follow up and the number of cigarettes the non-quitters smoked per smoking day (smoking intensity). Generalized estimating equations were used to test treatment condition, hypnotic suggestibility, and treatment expectancy as predictors of abstinence. The two interventions did not differ significantly in the proportion of participants who remained continuously abstinent throughout the follow-up period (CBT: 15.6%, HT: 15.0%) and also regarding the 7 days abstinence rates during the 12 months follow-up (CBT: 21.2%, HT: 16.7%). However, when controlling for hypnotic suggestibility, CBT showed significantly higher 7 days abstinence rates. In terms of the continuous abstinence rates, it can be concluded that the efficacy of hypnotherapeutic methods for smoking cessation seem to be comparable to established programs such as CBT.

RESUMEN

A number of case studies describing hypnotherapy in the treatment of anxiety disorder patients have already been published. Only a few randomized controlled trials (RCTs) investigated the efficacy of hypnotherapy but focused mainly on symptoms rather than specific mental disorders. The goal of this study was to investigate whether hypnotherapy (HT) was superior to a waitlist control group (WL) in the reduction of agoraphobia-related symptoms. Further goals were to report the feasibility of hypnotherapy as well as attrition and completion rates and detect (epi-)genetic variables, which might play a role in treatment outcome. This pilot study was based on a monocentric two-armed randomized controlled rater-blind clinical trial that was conducted between 2018 and 2020 with a waitlist control group. A total of 36 patients diagnosed with agoraphobia were randomized to either HT or WL. Patients in HT received individual outpatient treatment with hypnotherapy with 8 to 12 sessions for a period of 3 months. Patients in WL received HT after 3 months. Agoraphobia-related symptoms were assessed at baseline, after the treatment, and 3 months later in both groups with a clinician rating. The primary hypothesis concerning the difference between groups in the individual percentage symptom reduction could be confirmed in the intention-to-treat, not the per-protocol sample. Additionally, we applied repeated-measures analyses of variance and found a higher symptom decrease in HT compared with WL patients in three of the five imputed datasets. The dropout rate was low, and satisfaction with the treatment was high. HT patients experienced a strong symptom reduction after receiving hypnotherapy. WL patients improved slightly during the waiting period. The COMT Val108/158Met genotype had an effect on the agoraphobia-related symptoms as well as on COMT DNA methylation levels. This is the first study to indicate that hypnotherapy performed better than a waitlist control group regarding the reduction in anxiety symptoms in an RCT. Future studies should confirm the efficacy of hypnotherapy and compare the treatment with a standard treatment for anxiety disorders in a larger trial. Future studies should also investigate whether hypnotic susceptibility is associated with COMT Val108/158Met genotype and could predict treatment success for HT.

RESUMEN

OBJECTIVES: Previous studies reported about the influence of early changes on treatment response. However, the question of whether early changes can predict the subsequent course of depressive symptoms during treatment with psychotherapy has not yet been clearly answered. We aimed to investigate whether symptom course in the first weeks at the level of individual session can predict the further symptom progression on a session to session level during psychotherapy treatment in patients with Major Depression (MD). DESIGN: Monocentric randomized controlled trial with psychotherapeutic treatment either with cognitive-behavioural therapy (CBT) or hypnotherapy (HT). The longitudinal course of weekly depressive symptoms during the six months treatment period was examined. METHODS: In this RCT with 152 randomized patients suffering from current mild-to-moderate MD, depressive symptoms were assessed on a weekly basis during the 20 sessions' treatment with individual psychotherapy. We only included patients for which sufficient data for our analysis were available. Three different linear and quadratic mixed model analyses with random effects for each patient were tested: Early change was defined as the individual percentage symptom change during the first two, three, four and five weeks. Symptoms from session four, five, six and seven onward were predicted using different models, with early change added to the model in a final step. Calculating all models separately for CBT and HT lead to comparable results. RESULT: A slow symptom decrease after session four, five, six, seven onward to the end of the treatment was found. However, adding early change to the model, had no effect on the further symptom course in all models. CONCLUSION: Symptom changes at early stages of psychotherapy should not be considered as being predictive for further symptom course. PRACTITIONER POINTS: The individual early symptom change in a treatment with psychotherapy in the first two, three, four, or five weeks of treatment does not predict the subsequent symptom course from session four, five, six, or seven onward at a session to session level. Symptom changes at early stages of psychotherapy should not be considered as being predictive for further symptom course. We found a symptom reduction ranging from 3% to 16% in the first two, three, four, or five weeks. Treatment response between the first and last therapy session was found in 54.5%, the number of remitted patients (with PHQ-9 scores < 5) was 44.7%. A small symptom improvement of between 0.21 and 0.42 points in the PHQ-9 scores per week in later stages of psychotherapy is likely in all patients (with and without early symptom improvement).

RESUMEN

BACKGROUND: The diagnosis of pediatric bipolar disorders is a controversial topic. If this is mainly due to a bias against a diagnosis in younger children, then just changing the information about the age of a patient should influence the likelihood of a diagnosis despite otherwise identical symptoms. Therefore, we designed a study to test if the age of a patient will influence diagnostic decisions. We further attempted to replicate an earlier result with regard to "decreased need for sleep" as a salient symptom for mania. METHODS: We randomly sent 1 of 4 case vignettes describing a person with current mania to child/adolescents psychiatrists in Germany. This vignette was systematically varied with respect to age of the patient (6 vs 16 years) and the presence/absence of decreased need for sleep but always included sufficient criteria to diagnose a mania. RESULTS: One hundred sixteen responded and, overall, 63.8% of the respondents diagnosed a bipolar disorder in the person described in the vignette. Although age did not affect the likelihood of a bipolar diagnosis, the presence of decreased need for sleep did increase its likelihood. Furthermore, the number of core symptoms identified by the clinicians was closely linked to the likelihood of assigning a bipolar diagnosis. CONCLUSION: Certain symptoms such as the decreased need for sleep, and also elated mood and grandiosity, seem to be salient for some clinicians and influence their diagnoses. Biological age of the patient, however, does not seem to cause a systematic bias against a diagnosis of bipolar disorder in children.

RESUMEN

BACKGROUND: Methodologically well-designed RCTs concerning the efficacy of Hypnotherapy in the treatment of Major Depression are lacking. The aim of this study was to determine whether Hypnotherapy (HT) is not inferior to Cognitive Behavioral Therapy (CBT), the gold-standard psychotherapy, in the percentage reduction of depressive symptoms, assessed in mild to moderate Major Depression (MD). METHODS: This study reports the main results of a monocentric two-armed randomized-controlled rater-blind clinical trial. A total of 152 patients with MD were randomized to either CBT or HT receiving outpatient individual psychotherapy with 16 to 20 sessions for the duration of six months. The primary outcome was the mean percentage improvement in depressive symptoms assessed with the Montgomery-Asberg Depression Rating Scale (MADRS) before and after treatment. RESULTS: The difference in the mean percentage symptom reduction between HT and CBT was 2.8 (95% CI=-9.85 to 15.44) in the Intention-to-treat sample and 4.0 (95% CI=-9.27 to 17.27) in the Per Protocol sample (N=134). Concerning the pre-specified non-inferiority margin of -16.4, both results confirm the non-inferiority of HT to CBT. The results for the follow-ups six and twelve months after the end of the treatment support the primary results. LIMITATIONS: For ethical reasons the trial did not include a control group without treatment; therefore we can only indirectly conclude that both treatment conditions are effective. CONCLUSION: This is the first study to demonstrate that HT was not inferior to CBT in MD, while employing rigorous methodological standards.

RESUMEN

Objective: There is only some literature regarding the influence of verbal suggestions on cognitive performance in healthy volunteers. For example, the performance in a knowledge test was enhanced when participants were told that they had subliminally received the correct answer. However, enhancing cognitive performance only via verbal suggestions without prior conditioning phases has not yet been examined. The goal of our study was therefore to investigate the effects of a mental training based on verbal suggestions compared to a control training on cognitive performance in a student population using a balanced-placebo-design. Methods: In total, 103 participants were randomly assigned either to listening to a 20 min audio-taped mental training or to a 20 min philosophy lecture (control training) via headphones. Participants were individually tested before and after the training concerning their cognitive performance. Information about the type of training were varied in both intervention conditions ("You are part of our experimental condition and you will receive an effective mental training" or "You are part of our control group and you will receive the control condition"). At the end of the assessment, participants were asked what kind of training they believed they had received and how effective they would rate the received training. Results: Overall, the cognitive performance improved in all participants, F (1, 99) = 490.01, p < 0.001. Contrary to our hypotheses, we found no interaction of the type of training and type of instruction on the cognitive performance. Participants who rated the received training as being effective at the end of the experiment (regardless if it was the mental or the control training), have before experienced a greater improvement in their cognitive performance [F (2,100) = 7.26, p = 0.001] and showed higher scores in the ability to absorb [F (2, 99) = 3.75, p = 0.027]. Conclusion: The subjects' own experiences in the task might have influenced the rating of the training rather than the actual training or the information they receive regarding the type of training. This finding underlines the relevance of enhancing the subjective beliefs and self-efficacy in situations where cognitive attention processes are important and of individually tailoring mental trainings.

RESUMEN

BACKGROUND: Adherence to Internet interventions is often reported to be rather low and this might adversely impact the effectiveness of these interventions. We investigated if patient characteristics are associated with adherence, and if adherence is associated with treatment outcome in a large RCT of an Internet intervention for depression, the EVIDENT trial. METHODS: Patients were randomized to either care as usual (CAU) or CAU plus the Internet intervention Deprexis. A total of 509 participants with mild to moderate depressive symptoms were included in the intervention group and of interest for the present study. We assessed depression symptoms pre and post intervention (12 weeks). Patient characteristics, a self-rating screening for mental disorders, attitudes towards online interventions, and quality of life were assessed before randomization. RESULTS: Adherence in this study was good with on average seven hours of usage time and eight number of sessions spent with the intervention. Some of the patient characteristics (age, sex, depressive symptoms, and confidence in the effectiveness of the program) predicted higher number of sessions in different models (explaining in total between 15 and 25% of variance). Older age (ß = .16) and higher depressive symptoms (ß = .15) were associated with higher usage duration. Higher adherence to the program predicted a greater symptom reduction in depressive symptoms over 12 weeks (number of sessions: ß = .13, usage duration: ß = .14), however, this prediction could mostly be explained by receiving guidance (ß = .27 and .26). LIMITATIONS: Receiving guidance and symptom severity at baseline were confounded since only participants with a moderate symptom severity at baseline received e-mail support. Therefore no firm conclusions can be drawn from the association we observed between baseline symptom severity and usage intensity. CONCLUSIONS: We conclude that older age was associated with adherence and adherence was positively associated with outcome. The effects we have found were small however suggesting that adherence might also be influenced by further variables.

RESUMEN

INTRODUCTION: Despite a substantial number of studies providing evidence for the efficacy of psychological treatment for mild-to-moderate depression, maximally only 50% of participants respond to treatment, even when using gold-standard treatments such as cognitive-behavioural therapy (CBT) and interpersonal therapy. New approaches such as the 'third wave' psychotherapies have provided promising results; however, studies concerning the comparison with evidence-based treatments are lacking. This study aims to compare the efficacy of clinical hypnotherapy (HT) with gold-standard psychotherapy (CBT) in the treatment of mild-to-moderate major depressive episodes. METHODS AND ANALYSIS: The present study comprises a monocentric, two-armed, randomised-controlled, rater-blind (non-inferiority) clinical trial. A total of 160 participants with mild-to-moderate major depression episode will be randomly assigned to either CBT or HT involving 20 sessions of psychotherapy over a period of 24 weeks. We predict that the average improvement in the Montgomery-Åsberg Depression Rating Scale score will not be inferior in HT compared with CBT (non-inferiority hypothesis).Further outcome parameters will include the number of participants responding to treatment following the completion of treatment and 1 year after. Additionally, quality of life, treatment expectations and hypnotic susceptibility before and after end of treatment will be assessed. ETHICS AND DISSEMINATION: The study protocol and the documents for the informed consent have been approved by the Ethics Committee of the University Hospital Tuebingen (061/2015B02). The results of this trial will be submitted for publication in peer-reviewed journals, and will be presented at national and international conferences. TRIAL REGISTRATION NUMBER: NCT02375308; Pre-results.

RESUMEN

BACKGROUND: Cognitive factors might be the link between early attachment experiences and later depression. Similar cognitive vulnerability factors are discussed as relevant for both unipolar and bipolar disorders. The goals of the study were to test if there are any differences concerning attachment style and cognitive factors between remitted unipolar and bipolar patients compared to controls, and to test if the association between attachment style and depressive symptoms is mediated by cognitive factors. METHODS: A path model was tested in 182 participants (61 with remitted unipolar and 61 with remitted bipolar disorder, and 60 healthy subjects) in which adult attachment insecurity was hypothesized to affect subsyndromal depressive symptoms through the partial mediation of dysfunctional attitudes and self-esteem. RESULTS: No differences between patients with remitted unipolar and bipolar disorders concerning attachment style, dysfunctional attitudes, self-esteem, and subsyndromal depressive symptoms were found, but both groups reported a more dysfunctional pattern than healthy controls. The path models confirmed that the relationship between attachment style and depressive symptoms was mediated by the cognitive variables 'dysfunctional attitudes' and 'self-esteem'. LIMITATIONS: With the cross-sectional nature of the study, results cannot explain causal development over time. CONCLUSIONS: The results emphasize the relevance of a more elaborate understanding of cognitive and interpersonal factors in mood disorders. It is important to address cognitive biases and interpersonal experiences in treatment of mood disorders.

RESUMEN

Depression has been shown to be related to a variety of aberrant brain functions and structures. Particularly the investigation of alterations in functional connectivity (FC) in major depressive disorder (MDD) has been a promising endeavor, since a better understanding of pathological brain networks may foster our understanding of the disease. However, the underling mechanisms of aberrant FC in MDD are largely unclear. Using functional near-infrared spectroscopy (fNIRS) we investigated FC in the cortical parts of the default mode network (DMN) during resting-state in patients with current MDD. Additionally, we used qualitative and quantitative measures of psychological processes (e.g., state/trait rumination, mind-wandering) to investigate their contribution to differences in FC between depressed and non-depressed subjects. Our results indicate that 40% of the patients report spontaneous rumination during resting-state. Depressed subjects showed reduced FC in parts of the DMN compared to healthy controls. This finding was linked to the process of state/trait rumination. While rumination was negatively correlated with FC in the cortical parts of the DMN, mind-wandering showed positive associations.
