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.

Affectionate touch and diurnal oxytocin levels: An ecological momentary assessment study.

Background: Affectionate touch, which is vital for mental and physical health, was restricted during the Covid-19 pandemic. This study investigated the association between momentary affectionate touch and subjective well-being, as well as salivary oxytocin and cortisol in everyday life during the pandemic. Methods: In the first step, we measured anxiety and depression symptoms, loneliness and attitudes toward social touch in a large cross-sectional online survey (N = 1050). From this sample, N = 247 participants completed ecological momentary assessments over 2 days with six daily assessments by answering smartphone-based questions on affectionate touch and momentary mental state, and providing concomitant saliva samples for cortisol and oxytocin assessment. Results: Multilevel models showed that on a within-person level, affectionate touch was associated with decreased self-reported anxiety, general burden, stress, and increased oxytocin levels. On a between-person level, affectionate touch was associated with decreased cortisol levels and higher happiness. Moreover, individuals with a positive attitude toward social touch experiencing loneliness reported more mental health problems. Conclusions: Our results suggest that affectionate touch is linked to higher endogenous oxytocin in times of pandemic and lockdown and might buffer stress on a subjective and hormonal level. These findings might have implications for preventing mental burden during social contact restrictions. Funding: The study was funded by the German Research Foundation, the German Psychological Society, and German Academic Exchange Service.

Associations of SLC6A4 methylation with salivary cortisol, salivary alpha-amylase, and subjective stress in everyday life.

Dysregulations of the hypothalamic-pituitary-adrenal (HPA) and sympatho-adrenal medullary (SAM) axis are associated with mental and somatic illness. However, there is lack of knowledge regarding the molecular mechanisms underlying these effects. Epigenetic states in the serotonin transporter gene (SLC6A4) were shown to be associated with stress in various forms. We hypothesized that levels of DNA methylation (DNAm) of SLC6A4 would be associated with altered SAM- and HPA regulation in daily life. N = 74 healthy persons participated in the study. An ecological momentary assessment (EMA) approach was used to assess indicators of stress in daily life. Each day included six concurrent assessments of saliva, to quantify cortisol (sCort; HPA axis) and alpha-amylase (sAA; SAM axis), and to assess self-reports on subjective stress. To assess SLC6A4 DNAm, peripheral blood was drawn and analyzed via bisulfite pyrosequencing. All data were assessed in two waves three months apart, each including two days of EMA and the assessment of SLC6A4 DNAm. Data were analyzed using multilevel models. On the between-person level, higher average levels of SLC6A4 DNAm were associated with higher average levels of sAA, but not with average levels of sCort. On the within-person level, higher levels of SLC6A4 DNAm were associated with lower levels of sAA and sCort. There were no associations of subjective stress with SLC6A4 DNAm. The results help to clarify the association between environmental stress and stress axes regulation, pointing towards an important role of differential within- and between-person effects of SLC6A4 DNAm, which might shape this association.

Stress during the COVID-19 Pandemic Moderates Pain Perception and Momentary Oxytocin Levels.

Self-reported pain levels have been associated with increased stress levels during the COVID-19 pandemic. Less is known about the long-term effects of stress on individuals' physical and emotional pain levels and their associations with the neuropeptide hormone oxytocin. We aimed to predict momentary pain through individual stress levels and momentary oxytocin levels at genuinely high-stress phases, namely during COVID-related lockdowns. In a cross-sectional (n = 254) and a longitudinal (n = 196) assessment during lockdowns in Germany, participants completed a 2-day ecological momentary assessment (EMA) protocol (collecting six saliva samples on two consecutive days each and simultaneously reporting on stress, physical, and emotional pain levels) in 2020, as well as one year later, in 2021. Hierarchical linear modeling revealed significant positive associations between individuals' stress levels and physical pain, both cross-sectionally (b = 0.017; t(103) = 3.345; p = 0.001) and longitudinally (b = 0.009; t(110) = 2.025; p = 0.045). Similarly, subjective stress ratings showed significant positive associations with emotional pain on a within-person (b = 0.014; t(63) = 3.594; p < 0.001) as well as on a between-person (b = 0.026; t(122) = 5.191; p < 0.001) level. Participants further displayed significantly lower salivary oxytocin when experiencing higher levels of emotional pain (b = -0.120; t(163) = -2.493; p = 0.014). In addition, high-stress levels significantly moderated the association between physical pain and salivary oxytocin (b = -0.012; t(32) = -2.150; p = 0.039). Based on mechanistic and experimental research, oxytocinergic mechanisms have long been suggested to modulate pain experiences, however, this has not yet been investigated in everyday life. Our data, which was collected from a large sample experiencing continued stress, in this case, during the COVID-19 pandemic, suggests that individuals experience more intense physical pain and elevated stress levels, as shown by particularly low salivary oxytocin concentrations.

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.

Loneliness and diurnal cortisol levels during COVID-19 lockdown: the roles of living situation, relationship status and relationship quality.

Loneliness and social isolation have become increasing concerns during COVID-19 lockdown through neuroendocrine stress-reactions, physical and mental health problems. We investigated living situation, relationship status and quality as potential moderators for trait and state loneliness and salivary cortisol levels (hormonal stress-responses) in healthy adults during the first lockdown in Germany. N = 1242 participants (mean age = 36.32, 78% female) filled out an online questionnaire on demographics, trait loneliness and relationship quality. Next, N = 247 (mean age = 32.6, 70% female) completed ecological momentary assessment (EMA), collecting twelve saliva samples on 2 days and simultaneously reporting their momentary loneliness levels. Divorced/widowed showed highest trait loneliness, followed by singles and partnerships. The latter displayed lower momentary loneliness and cortisol levels compared to singles. Relationship satisfaction significantly reduced loneliness levels in participants with a partner and those who were living apart from their partner reported loneliness levels similar to singles living alone. Living alone was associated with higher loneliness levels. Hierarchical linear models revealed a significant cross-level interaction between relationship status and momentary loneliness in predicting cortisol. The results imply that widowhood, being single, living alone and low relationship quality represent risk factors for loneliness and having a partner buffers neuroendocrine stress responses during lockdown.

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.

Still With Me? Assessing the Persisting Relationship to a Deceased Loved-One - Validation of the "Continuing Bonds Scale" in a German Population.

Continuing the bond (CB) to a deceased loved one plays a clinically significant role in grief. We validated the Continuing Bonds Scale (CBS) examining externalized CB (illusions and hallucinations) versus internalized CB (use of the deceased as a secure base) in relation to risk factors of complicated grief and bereavement-related adjustment. Data from 364 bereaved German participants on CBS, Inventory of Complicated Grief (ICG), and Posttraumatic Personal Growth Inventory (PPGI) entered an exploratory factor analysis. This yielded a two-factor-solution representing externalized and internalized CB (KMO = .89, χ2 = 2100.5, df = 120). Both factors demonstrated high internal consistency (Cronbach's α = .87). ICG and PPGI highly correlated with externalized and internalized CB. Cause of death and feelings of responsibility were associated with externalized CB. In the future, the use of the CBS could help predict problems in grief processing and consequently implement early interventions.

Effects of a mindfulness-based intervention on mindfulness, stress, salivary alpha-amylase and cortisol in everyday life.

A large body of literature has shown the effectiveness of mindfulness-based interventions (MBI) on stress-reduction. However, little is known about their effects on psychobiological stress-markers in daily life through an ecological momentary assessment approach. Our study examines the effects of MBI on state mindfulness, perceived stress, and indicators of sympathetic-nervous-system (saliva alpha-amylase, sAA) and hypothalamic-pituitary-adrenal-axis (saliva cortisol, sCort) activation in daily life. Twenty-eight individuals participated in a three-month MBI (IG) and were compared to 46 controls (CG). An ecological momentary assessment (EMA) was used to assess mindfulness, stress, sAA and sCort at six measurements per day on two days each before and after the MBI. Multilevel-modeling was used to analyze the data on a moment-to-moment and averaged day-level. The IG showed decreased sAA levels (AUCg) from pre to post, while the CG showed increases. Furthermore, diurnal decreases in sCort (AUCi) were pronounced in the IG compared to the CG. On a momentary basis, mindfulness was associated with lower stress and sAA levels, but not sCort. As such, we show that MBI can reduce sympathetic and to a lesser extent hypothalamic-pituitary-adrenal activation in daily life. Increased mindfulness can momentarily decrease stress and stress-related autonomic activation with implications for health. Our results emphasize the importance of brief interventions that can be easily integrated into everyday life.

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.

Neuroendocrine mechanisms of grief and bereavement: A systematic review and implications for future interventions.

Bereavement is associated with many negative behavioural, psychological and physiological consequences and leads to an increased risk of mortality and morbidity. However, studies specifically examining neuroendocrine mechanisms of grief and bereavement have yet to be reviewed. This systematic review is a synthesis of the latest evidence in this field and aims to draw conclusions about the implications of neurobiological findings on the development of new interventions. PRISMA guidelines for systematic reviews were used to search for articles assessing neuroendocrine correlates of grief. Findings were qualitatively summarised. The National Heart, Lung, and Blood Institute Study Assessment Tool was used to assess the quality of the included studies. Out of 460 papers, 20 met the inclusion criteria. However, most were of fair quality only. As a neuroendocrine marker, the majority of the studies reported cortisol as the outcome measure and found elevated mean cortisol levels, flattened diurnal cortisol slopes and higher morning cortisol in bereaved subjects. Cortisol alterations were moderated by individual differences such as emotional reaction to grief, depressive symptoms, grief severity, closeness to the deceased and age or gender. Research on neuroendocrine mechanisms of grief is still in its early stages regarding grief measures and the use and timing of neuroendocrine assessments. Most of the studies focus on cortisol as outcome, and only limited data exist on other biomarkers such as oxytocin. Future research might consider assessing a broader range of neuroendocrine markers and use longitudinal designs with a focus on the psychobiological reactions to loss. Based on this, individually tailored psychosocial interventions, possibly in the palliative care context, might be developed to prevent prolonged grief disorder.

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.

Stress-reducing effects of a brief mindfulness intervention in palliative care: Results from a randomised, crossover study.

OBJECTIVE: Mindfulness-based interventions are a widely used and highly accepted adjunct treatment in oncology. Due to a paucity of research in advanced cancer and other terminal illnesses, we aimed to evaluate the stress-reducing effects of a brief, standardised mindfulness intervention for use in palliative care. METHODS: This study was a randomised, crossover trial where patients participated in both a single mindfulness intervention and a resting state control condition. The order of the conditions was randomised. Study outcomes encompassed self-report data on stress and well-being and measures of heart rate variability. All outcome data were measured at four times per day. RESULTS: Forty-two patients participated in this study. We found significantly stronger reductions in self-rated stress and mean heart rate as well as an increase in heart rate variability after the mindfulness intervention. Psychophysiological effects were strongest in the immediate pre- to post-intervention comparison, while the effect on subjective stress persisted after 20 to 40 min. No significant differences were found for self-rated well-being. CONCLUSIONS: Despite the rather small magnitude of effects, the brief mindfulness intervention showed to be effective and accepted by patients in very advanced stages of a disease and could be offered by trained healthcare professionals in palliative care.

Psychosocial Interventions for Pain Management in Advanced Cancer Patients: a Systematic Review and Meta-analysis.

PURPOSE OF REVIEW: This systematic review and meta-analysis aimed to synthesize the evidence on the effects of psychosocial interventions on pain in advanced cancer patients. RECENT FINDINGS: The included studies investigated the effects of relaxation techniques, cognitive-behavioral therapy, music therapy, mindfulness- and acceptance-based interventions, and supportive-expressive group therapy. Overall, we found a small, but significant effect on pain intensity (d = - 0.29, CI = - 0.54 to - 0.05). Effect sizes were highly heterogeneous between studies. We did not find evidence for the superiority of any of the intervention types. However, psychosocial interventions may be more effective if they specifically targeted pain distress as the primary outcome. Although findings were mixed, psychosocial interventions can be recommended to complement comprehensive care to alleviate pain in patients facing an advanced or terminal stage of the disease. Future research should develop innovative interventions tailored specifically for pain relief.

[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.

Oxytocin Modulates the Cognitive Appraisal of the Own and Others Close Intimate Relationships.

Close and intimate relationships are important promoters of health. Oxytocin and its association with social cognition have been investigated in a large number of studies, especially highlighting the neuropeptide's involvement in attachment behavior and intimate relationships. However, mixed findings on exogenous oxytocin application have led to the focus on moderators and mediators, suggesting that the effects are depended on specific factors - namely context and salience. The objective of the current study was to assess the effect of intranasal oxytocin on social appraisal of own and others' close intimate relationship characteristics. Different characteristics of relationships, including trust or closeness, between romantic couples (unknown and own) were assessed using the Couple Appraisal Task. In a randomized controlled double-blind cross-over within subject design, N = 71 healthy men and women were investigated after receiving first intranasal oxytocin and 2 weeks later placebo, or vice versa. We found an oxytocin-induced increase in the positive appraisal of one's own overall relationship characteristics but not in the evaluation of the relationship of others. The present study - one of the first of its kind administrating oxytocin in a repeated measures cross-over design - adds further evidence to the mediating role of oxytocin in social cognition, specifically with regard to romantic relationship characteristics.
