A compassion-based treatment for couples with the female partner suffering from current depressive disorder: A randomized-controlled trial.

BACKGROUND: Studies have shown that depression and interpersonal relationships are interdependently connected and that including the intimate partner in treatment for depression has beneficial effects. Given evidence that compassion is both an interpersonal quality and a promising treatment target, the goal of this study was to examine the effects of a compassion-based, contemplative treatment for couples employing a multi-method approach for evaluation. METHODS: In a pre-post-follow-up design, n = 53 different-sex couples including women with current depression were randomly assigned to a 10-week-long CBCT®-fC (Cognitively-Based Compassion Training/intervention for couples) or treatment-as-usual (TAU) condition. Multi-level linear regression models and post-hoc contrasts were calculated to determine changes in depressive symptoms, mindfulness and self-compassion, interpersonal functioning and neuroendocrine markers collected during a partnership appreciation task (PAT) in the laboratory before and after CBCT-fC treatment. RESULTS: While CBCT-fC led to a comparable decrease of depressive symptoms as TAU, the training specifically increased self-compassion and mindfulness versus TAU. Interestingly, interpersonal functioning did not improve, which was also reflected in participants' preferred self-focus in-between-session practices, instead of practices with interpersonal focus. There were no group-specific changes in psychobiological stress-marker reactivity. CONCLUSIONS: CBCT-fC was effective in decreasing current depressive symptomatology and increasing mindfulness, and self-compassion. Especially the motivation to participate, such as improving interpersonal functioning, should be addressed and intrinsic motives of the partners to be involved. In highly burdened individuals, self-regulation may need to be improved before co-regulation can be addressed, which would requiring longer treatments. Facilitating factors for engaging in the practice between-sessions seem meaningful.

Effects of intranasal oxytocin and positive couple interaction on immune factors in skin wounds.

BACKGROUND: Intimate social relationships improve individual health and longevity, an effect which is supposed to be mediated through stress-sensitive endocrine and immune mechanisms in response to positive interaction behavior. On a neuroendocrine level, oxytocin (OT) buffers stress responses, modulates social attachment behavior and has been associated with cytokine expression. Consequently, the aim of the present study was to investigate instructed positive couple interaction, observed behavior, and OT in their effect on immune function. METHODS: In a 4-group design, 80 healthy couples (N = 160 individuals) received four standard dermal suction blister wounds and were randomized to instructed positive interaction/control and intranasal OT/placebo. Unstimulated cytokines (IL-1ß, IL-6, TNF-α) were assessed from wound liquid at 40 min, 105 min and 24 hrs after wounding. RESULTS: Overall, group assignment did not affect friendly or dominant behavior during the interaction sequence. IL-1ß and IL-6 levels, however, were moderated by group assignment with lowest levels in women in the positive interaction and OT condition in IL-1 and highest levels in IL-6. TNF-α responses to wounding were not affected from group assignment, however observed friendliness in women was associated with lower TNF-α levels. DISCUSSION: These findings support the immune-regulating role of friendly behavior in romantic couples. Above this, the data provide the first empirical evidence that an intervention that simultaneously targets neuroendocrine mediators and behavior could affect immune function in a sex specific manner and with potential long-term health relevance.

Feeling low and unhappy together? An actor-partner-interdependence model uncovering the linkage between different operationalizations of relationship quality and depression in different-sex couples.

Some studies suggest a bi-directional association between low relationship quality and depression. However, the social impact of depression and the potential preventative effects of healthy relationships are not yet sufficiently understood, as studies have shown heterogenous results for effects in both directions. Therefore, the main aim of this study was to differentiate the actor and partner effects of this association more comprehensively using two measures to capture characteristics of relationship quality-firstly regarding general aspects of social system quality and secondly considering specific aspects of the romantic relationship. 110 different-sex couples were included, being separated in partners with highly pronounced depressive symptoms in women (Cw/DW) versus partners with low depressive symptoms (LDCs). We investigated effects cross-sectionally using multi-group analyses to predict relationship (couple specific questionnaire: PFB) versus system quality (general system quality questionnaire: EVOS) in a step-by-step approach, modelling actor and partner effects with variation within and across both groups and then comparing the results to models with equal actor and partner effects. Depression was measured with the PHQ-9. With regard to the relationship between depressive symptoms and system quality, the model that constrained actor and partner effects to be equal across both groups was preferred and showed negative significant actor effects across gender and groups. Concerning the association between depressive symptoms and relationship quality, the model constraining actor and partner effects to be equal within groups had the best fit to the data and revealed a negative partner effect in LDCs. Conclusions Controlling for the moderating variable of clinically relevant depressive symptoms, we found evidence for actor and partner effects, which differed between the two relationship measures. This underlines the importance to reflect how relationship quality is operationalized. The negative partner effect on relationship quality in LDCs emphasizes that even in a non-clinical context, depressive symptoms negatively impact the perceived relationship quality of both women and men. This suggests that addressing the relationship is important in non-clinical preventive contexts and calls for integrating the partner into counselling or trainings.

Change Mechanism of Cognitively-Based Compassion Training for Couples with Depression: An Exploratory Empirical Investigation of Process Variables.

Objective: Compassion training seems to be a promising intervention for couples to improve individual psychopathology and relationship quality. Beyond studying the efficacy of training such as Cognitively-Based Compassion Training for Couples (CBCT-fC), it is important to gain insights into the putative mechanisms along the process. Methods: Theoretically derived presumed mechanisms of compassion training (clarification of values, self-regulation, decentering, and exposure) and additional therapeutic factors (emotional bond, social learning, and clarification of meaning) were studied over the course of a 10-session-long group-based CBCT-fC among women with depressive disorders. Results: Dyadic growth curve models indicated that emotional bond, social learning, and clarification of meaning increase over time in both partners. In decentering and clarification of values, women who suffered from depression showed a larger increase than men, while men had higher values at the start of the training. Conclusions: Women with depression seem to benefit from CBCT-fC in terms of an increase in decentering and value clarification, important mechanisms of compassion training. This study is the first to show that theoretically derived mechanisms of compassion and additional therapeutic factors can describe the process along secular contemplative training sessions, which are increasingly implemented in the health care system. Future studies should explore the relationship of mechanisms and the outcome along the process of the training. Study Registration: Trial registration number NCT03080025.

A new way to measure partner burden in depression: Construction, validation, and sensitivity to change of the partner burden in depression questionnaire.

Depression occurs in an interpersonal dynamic and living with a depressed person can lead to a significant burden on the partner. Instruments measuring burden do not address couples and often measure caregiving for individuals with schizophrenic disorders. The partner burden in depression (PBD) questionnaire is a new instrument measuring PBD by asking individuals, (1) which symptoms they can observe in their depressed partners and (2) to which degree this burdens them. Hence, PBD combines measuring the awareness of observed depressive symptoms and the resulting burden. Additionally, it addresses aspects unique to couple relationships. Our German validation confirmed a one-factor model with 12 items. The PBD had good psychometric properties and was sensitive to change. Partner burden predicted self-reported depressive symptoms (PHQ-9) over time. PBD is short, easily applicable in research and practice and can add to the understanding of partner effects in depression.

Mindfulness-Based Couple Interventions: A Systematic Literature Review.

Over the past decades, mindfulness-based interventions have been shown to improve individual health and well-being in clinical and nonclinical settings. More recently, secular contemplative trainings were adapted to the couple context as research showed satisfying couple relationships to be one of the strongest predictors of physical and mental health. Mindfulness-based interventions hence seem to be a promising treatment in couple counseling and therapy in both clinical and nonclinical settings. Therefore, we conducted a systematic review to provide an overview of the emerging literature in the field of mindfulness-based interventions for couples and other dyads. Overall, sixteen studies met the inclusion criteria. To summarize the heterogeneous quantitative literature regarding individual outcomes, mindfulness interventions for couples seem to increase mindfulness, self-compassion, well-being, and quality of life. Additionally, we found initial evidence of beneficial effects on relieving psychopathological symptoms and psychobiological stress measures. Measures of relationship quality were the predominant dyadic outcome. Based on these studies, we cautiously conclude that mindfulness trainings can enhance relationship quality. Practitioners should be aware that mindfulness-based interventions for couples can potentially improve the perceived relationship quality between partners and the individual burden. Future studies should expand the field, particularly with regard to other contemplative practices for couples such as compassion interventions.

Durante las últimas décadas, se ha demostrado que las intervenciones basadas en la conciencia plena mejoran la salud y el bienestar en entornos clínicos y no clínicos. Recientemente, se adaptaron capacitaciones contemplativas seculares al contexto de la pareja, ya que las investigaciones demostraron que las relaciones satisfactorias de pareja son uno de los predictores más firmes de la salud mental y física. Por consiguiente, las intervenciones basadas en la conciencia plena parecen ser un tratamiento prometedor en la terapia de pareja, tanto en entornos clínicos como no clínicos. Por lo tanto, realizamos un análisis sistemático para ofrecer una descripción general de las publicaciones que han surgido en el ámbito de las intervenciones basadas en la conciencia plena para parejas y otras díadas. En general, dieciséis estudios cumplieron con los criterios de inclusión. Para resumir las publicaciones cuantitativas heterogéneas con respecto a los resultados individuales, las intervenciones de conciencia plena para parejas parecen aumentar la conciencia, la autocompasión, el bienestar y la calidad de vida. Además, descubrimos pruebas iniciales de efectos beneficiosos en el alivio de los síntomas psicopatológicos y en las valoraciones de estrés psicobiológico. Las valoraciones de la calidad de la relación fueron el resultado diádico predominante. Sobre la base de estos estudios, llegamos prudentemente a la conclusión de que las capacitaciones en conciencia plena pueden mejorar la calidad de la relación. Los profesionales deben estar al tanto de que las intervenciones para parejas basadas en la conciencia plena pueden mejorar la calidad de la relación percibida entre los integrantes de la pareja y el agobio individual. Los estudios futuros deben ampliar el ámbito, particularmente con respecto a otras prácticas contemplativas para parejas, como las intervenciones centradas en la compasión.

Instructed Partnership Appreciation in Depression: Effects on Mood, Momentary Relationship Satisfaction, and Psychobiological Arousal.

BACKGROUND: Depressive disorders are associated with attentional bias and social anhedonia. There is evidence supporting the hypothesis that depressed individuals participate less in potentially rewarding social situations and exhibit alterations in stress reactivity. With the present study, we aimed at investigating the affective and psychobiological response of couples with a depressed (female) partner in an instructed partnership appreciation task (PAT) that included positive and appreciative communication. METHODS: In a quasi-experimental repeated-measures design, depressive couples (DCs)-i.e., the female partner being diagnosed with a depressive disorder-were compared to non-depressive couples (NDCs). Study outcomes were the PAT-induced changes in state mood, momentary relationship satisfaction, salivary cortisol, and salivary alpha-amylase. Additionally, we assessed psychometric baseline data on depression, relationship quality, social support, and chronic stress. Data was analyzed using multilevel modeling. RESULTS: A total of 184 individuals from N = 47 DCs and N = 45 NDCs were included. DCs were characterized by higher depressiveness, lower relationship quality, less actually received social support from the partner, and higher chronic stress than NDCs. Manipulation checks led to the additional exclusion of two couples. Regarding mood, depressed women showed lower baseline scores and no significant differences in mood increase compared to non-depressed women (p = 0.107). Increases in relationship satisfaction were significantly stronger in the depressed group (p = 0.035). In addition, we found a significantly stronger cortisol increase in depressed women, but only if relationship duration was taken into account as a moderating factor (p = 0.022). No significant group differences were found for women's amylase trajectories or for sex-dependent interaction effects on the couple level (all p > 0.05). CONCLUSIONS: Instructed engagement in positive couple interaction may require high effort and increased psychobiological arousal, but may finally result in emotional and social benefits in depressed women. While these findings encourage speculations about the therapeutic application of instructed partnership appreciation, more research is needed on the effectiveness of such interventions and on the moderating role of relationship duration in depression and couple functioning.

Caspr2 interacts with type 1 inositol 1,4,5-trisphosphate receptor in the developing cerebellum and regulates Purkinje cell morphology.

Contactin-associated protein-like 2 (Caspr2) is a neurexin-like protein that has been associated with numerous neurological conditions. However, the specific functional roles that Caspr2 plays in the central nervous system and their underlying mechanisms remain incompletely understood. Here, we report on a functional role for Caspr2 in the developing cerebellum. Using a combination of confocal microscopy, biochemical analyses, and behavioral testing, we show that loss of Caspr2 in the Cntnap2-/- knockout mouse results in impaired Purkinje cell dendritic development, altered intracellular signaling, and motor coordination deficits. We also find that Caspr2 is highly enriched at synaptic specializations in the cerebellum. Using a proteomics approach, we identify type 1 inositol 1,4,5-trisphosphate receptor (IP3R1) as a specific synaptic interaction partner of the Caspr2 extracellular domain in the molecular layer of the developing cerebellum. The interaction of the Caspr2 extracellular domain with IP3R1 inhibits IP3R1-mediated changes in cellular morphology. Together, our work defines a mechanism by which Caspr2 controls the development and function of the cerebellum and advances our understanding of how Caspr2 dysfunction might lead to specific brain disorders.

[Change Mechanisms in Group Therapy: A Questionnaire to Measure Therapeutic Perspectives]. / Wirkfaktoren in der Gruppentherapie: Fragebogen zur Messung der therapeutischen Perspektive.

Group therapy was shown to be an effective and economic intervention. To date few instruments exist to empirically assess mechanisms of therapeutic change in group therapy. The Group Therapy Process Questionnaire for Therapists (FEPiG-T) measuring change mechanisms in group therapy as viewed from the perspectives of therapists was developed and validated in this study based on the conceptualizations of Grawe,Yalom and Bordin and in reference to the previously developed measure for patients. The FEPiG-T subscales show good internal consistencies and small to large correlations with convergent measures. Subscales at beginning of therapy correlated with improvement of interpersonal problems over time. Further associations with symptom scales remained more vague. However, intersections with the established version for patients allow routinely implemented evaluation of the 2 perspectives in clinical practice, but inevitably need careful interpretation where the instruments differ in their factor structure.

Enhancing Social Interaction in Depression (SIDE study): protocol of a randomised controlled trial on the effects of a Cognitively Based Compassion Training (CBCT) for couples.

INTRODUCTION: Positive social interactions (PSIs) and stable relationships can exert substantial benefits on health. However, patients suffering from depression benefit less from these health-promoting effects. Moreover, relationship quality and even partners' health has been found to be negatively affected by depressive symptomatology, which may result in overall impairments in social functioning of a romantic couple. Psychobiological research indicates that these impairments may be accompanied by a maladaptive regulation of the patient's neuroendocrine response to external stressors. Concerning the improvement of social functioning, first studies showed promising results of "Cognitively Based Compassion Training (CBCT®)". However, randomised trials are still scarce. Previous programmes did not involve participation of the patient's romantic partner. Therefore, the present study aims to investigate whether a CBCT® programme adapted for couples (CBCT®-fC) can improve depressive symptoms, distress, social interaction skills and the neurobiological regulation of stress. METHODS AND ANALYSIS: Couples with the female partner suffering from depression will be invited to participate in a pre-to-post intervention assessment on two consecutive days, respectively, involving a standardised PSI task, eye-tracking, ECG recordings, saliva-sampling, blood-sampling and questionnaire data. After baseline assessment, participating couples will be randomised to either a 10 week CBCT®-fC or to a treatment as usual control condition. The primary endpoint is the reduction of depressive symptoms measured by the Hamilton Depression Rating Scale. Secondary outcomes encompass self-rated depression (Beck Depression Inventory), attention towards the partners face during PSI (eye tracking), stress-related biomarkers (cortisol, α-amylase, interleukin (IL)-1ß/IL-6, heart rate variability), methylation of oxytocin-receptor-genes and serotonin-transporter-genes and self-ratings of psychological constructs such as relationship quality and empathy. ETHICS AND DISSEMINATION: Ethical approval has been obtained by the Ethics Committee of the Medical Faculty Heidelberg. Results will be presented in international, peer-reviewed journals and on conferences in the field of clinical psychology and psychiatry. TRIAL REGISTRATION NUMBER: NCT03080025.

Disruption of a Structurally Important Extracellular Element in the Glycine Receptor Leads to Decreased Synaptic Integration and Signaling Resulting in Severe Startle Disease.

Functional impairments or trafficking defects of inhibitory glycine receptors (GlyRs) have been linked to human hyperekplexia/startle disease and autism spectrum disorders. We found that a lack of synaptic integration of GlyRs, together with disrupted receptor function, is responsible for a lethal startle phenotype in a novel spontaneous mouse mutant shaky, caused by a missense mutation, Q177K, located in the extracellular ß8-ß9 loop of the GlyR α1 subunit. Recently, structural data provided evidence that the flexibility of the ß8-ß9 loop is crucial for conformational transitions during opening and closing of the ion channel and represents a novel allosteric binding site in Cys-loop receptors. We identified the underlying neuropathological mechanisms in male and female shaky mice through a combination of protein biochemistry, immunocytochemistry, and both in vivo and in vitro electrophysiology. Increased expression of the mutant GlyR α1Q177K subunit in vivo was not sufficient to compensate for a decrease in synaptic integration of α1Q177Kß GlyRs. The remaining synaptic heteromeric α1Q177Kß GlyRs had decreased current amplitudes with significantly faster decay times. This functional disruption reveals an important role for the GlyR α1 subunit ß8-ß9 loop in initiating rearrangements within the extracellular-transmembrane GlyR interface and that this structural element is vital for inhibitory GlyR function, signaling, and synaptic clustering.SIGNIFICANCE STATEMENT GlyR dysfunction underlies neuromotor deficits in startle disease and autism spectrum disorders. We describe an extracellular GlyR α1 subunit mutation (Q177K) in a novel mouse startle disease mutant shaky Structural data suggest that during signal transduction, large transitions of the ß8-ß9 loop occur in response to neurotransmitter binding. Disruption of the ß8-ß9 loop by the Q177K mutation results in a disruption of hydrogen bonds between Q177 and the ligand-binding residue R65. Functionally, the Q177K change resulted in decreased current amplitudes, altered desensitization decay time constants, and reduced GlyR clustering and synaptic strength. The GlyR ß8-ß9 loop is therefore an essential regulator of conformational rearrangements during ion channel opening and closing.
