The link between leadership and mental health at the workplace is well established by prior research. However, most of the studies have addressed this relationship from a single-source perspective. ...The aim of this study was to examine how supervisor and employee ratings of health-oriented leadership correspond to each other and which sources are predictive for employee mental health. We assessed data within 99 teams (headed by 99 supervisors) containing 713 employees in 11 different companies in Southern Germany. Supervisors and their staff completed questionnaires on the supervisors' health-oriented staff-care dimensions awareness, value of health and health behavior (Health-Oriented Leadership Scale, HoL) and current mental distress (Hospital Anxiety and Depression Scale, HADS). Hierarchical linear models revealed that supervisors' self-ratings were significantly related to their employees' ratings (at the team level) only on the health behavior dimension, but not on the health awareness and value of health dimensions. Also, supervisors rated themselves significantly higher on HoL compared to their employees. Employee ratings of HoL significantly predicted their own level of mental distress (direct within-level effect), whereas supervisor ratings of HoL did not predict employees' mental distress at the team level (direct cross-level effect). Supervisors' self-ratings of HoL did not influence the relationship between employee ratings of HoL and their mental distress on an individual level (cross-level interaction). These results highlight the complex relationship between multisource assessments of HoL and employee mental health, emphasizing the importance of subjective perception for mental health. Future studies should investigate under which conditions supervisor and employee ratings correspond to each other and are predictive for mental health at the workplace.
A markedly negative self-image and pervasive shame proneness have consistently been associated with borderline personality disorder (BPD). The present experimental study investigated the intensity of ...negative emotional responses with a focus on shame in BPD compared to healthy control persons (HCs) during an experimental paradigm promoting self-awareness, self-reflection, and self-evaluation. Furthermore, the relationship between levels of state shame during the experiment and shame proneness in BPD compared to HCs was examined.
A sample of 62 individuals with BPD and 47 HCs participated in the study. During the experimental paradigm, participants were presented with photos of (i) the own face, (ii) the face of a well-known person, and (iii) of an unknown person. They were asked to describe positive facets of these faces. Participants rated the intensity of negative emotions induced by the experimental task as well the pleasantness of the presented faces. Shame-proneness was assessed using the Test of the Self-Conscious Affect (TOSCA-3).
Individuals with BPD experienced significantly higher levels of negative emotions than HCs both before and during the experimental task. While HC participants responded to their own face particularly with an increase in shame compared to the other-referential condition, the BPD patients responded above all with a strong increase of disgust. Furthermore, the confrontation with an unknown or well-known face resulted in a strong increase of envy in BPD compared to HC. Individuals with BPD reported higher levels of shame-proneness than HCs. Higher levels of shame-proneness were related to higher levels of state shame during the experiment across all participants.
Our study is the first experimental study on negative emotional responses and its relationship to shame proneness in BPD compared to HC using the own face as a cue promoting self-awareness, self-reflection, and self-evaluation. Our data confirm a prominent role of shame when describing positive features of the own face, but they emphasize also disgust and envy as distinct emotional experience characterizing individuals with BPD when being confronted with the self.
Early experiences of childhood sexual or physical abuse are often associated with functional impairments, reduced well-being and interpersonal problems in adulthood. Prior studies have addressed ...whether the traumatic experience itself or adult psychopathology is linked to these limitations. To approach this question, individuals with posttraumatic stress disorder (PTSD) and healthy individuals with and without a history of child abuse were investigated. We used global positioning system (GPS) tracking to study temporal and spatial limitations in the participants' real-life activity space over the course of one week. The sample consisted of 228 female participants: 150 women with PTSD and emotional instability with a history of child abuse, 35 mentally healthy women with a history of child abuse (healthy trauma controls, HTC) and 43 mentally healthy women without any traumatic experiences in their past (healthy controls, HC). Both traumatized groups-i.e. the PTSD and the HTC group-had smaller movement radii than the HC group on the weekends, but neither spent significantly less time away from home than HC. Some differences between PTSD and HC in movement radius seem to be related to correlates of PTSD psychopathology, like depression and physical health. Yet group differences between HTC and HC in movement radius remained even when contextual and individual health variables were included in the model, indicating specific effects of traumatic experiences on activity space. Experiences of child abuse could limit activity space later in life, regardless of whether PTSD develops.
Background
Interpersonal impairments in borderline personality disorder (BPD) are characterised by a lack in the sense of belonging and the fear of being excluded. One feature of interactions that ...can promote a sense of social belonging is interpersonal touch. While some studies suggest that individuals with BPD experience social touch as less pleasurable than healthy individuals (HCs), there are no studies that investigated whether this difference is associated with feeling less socially connected. This question is particularly important during the COVID-19 pandemic, since one central behavioural recommendation is “social distancing”. An increase in loneliness has been discussed as a consequence and it has been suggested that individuals with BPD may be particularly burdened. However, the primary goal of “social distancing” is not preventing social contacts, but physical proximity. In our study we investigated the interplay between feeling close to others, contact frequency and the appraisal of social touch in BPD. We were additionally interested in whether these factors contribute to the burden through “physical distancing”.
Methods
We assessed subjective and objective social isolation, the need, importance, and liking of social touch, as well as the burden through “physical distancing” policies in 130 women (61 BPD and 69 HCs).
Results
Participants of the BPD group reported higher loneliness, less social contacts and a lower need for, importance and liking of social touch compared to HCs. Larger social networks, higher frequency of in-person contacts and higher liking and importance of social touch were associated with lower levels of loneliness. Both groups did not differ regarding their burden through “physical distancing”. A higher need for and lower importance of social touch predicted a higher burden through “physical distancing”.
Conclusions
A positive appraisal of social touch was associated with less loneliness, independently of an individual's objective social isolation. In BPD, impairments of this fundamental facet of social interaction might hamper forming and strengthening of social bonds and contribute to the patients' interpersonal dysfunction. Changing the attitude towards social touch and in consequence its liking and importance in social interaction might provide one avenue to improve the sense of social connectedness in these patients.
Dysfunctional fear responses play a central role in many mental disorders. New insights in learning and memory suggest that pharmacological and behavioural interventions during the reconsolidation of ...reactivated fear memories may increase the efficacy of therapeutic interventions. It has been proposed that interventions applied during reconsolidation may modify the original fear memory, and thus prevent the spontaneous recovery and reinstatement of the fear response.
We investigated whether pharmacological (propranolol) and behavioural (reappraisal, multisensory stimulation) interventions reduce fear memory, and prevent reinstatement of fear in comparison to a placebo control group. Eighty healthy female subjects underwent a differential fear conditioning procedure with three stimuli (CS). Two of these (CS+) were paired with an electric shock on day 1. On day 2, 20 subjects were pseudo-randomly assigned to either the propranolol or placebo condition, or underwent one of the two behavioural interventions after one of the two CS+ was reactivated. On day 3, all subjects underwent an extinction phase, followed by a reinstatement test. Dependent variables were US expectancy ratings, fear-potentiated startle, and skin conductance response.
Differential fear responses to the reactivated and non-reactivated CS+ were observed only in the propranolol condition. Here, the non-reactivated CS+ evoked stronger fear-potentiated startle-responses compared to the placebo group. None of the interventions prevented the return of the extinguished fear response after re-exposure to the unconditioned stimulus.
Our data are in line with an increasing body of research stating that the occurrence of reconsolidation may be constrained by boundary conditions such as subtle differences in experimental manipulations and instructions. In conclusion, our findings do not support a beneficial effect in using reconsolidation processes to enhance effects of psychotherapeutic interventions. This implies that more research is required before therapeutic interventions may benefit from a combination with reconsolidation processes.
Social affiliation is essential for many species and gains significant importance during adolescence. Disturbances in social affiliation, in particular social rejection experiences during ...adolescence, affect an individual's well-being and are involved in the emergence of psychiatric disorders. The underlying mechanisms are still unknown, partly because of a lack of valid animal models. By using a novel animal model for social peer-rejection, which compromises adolescent rats in their ability to appropriately engage in playful activities, here we report on persistent impairments in social behavior and dysregulations in the endocannabinoid (eCB) system. From postnatal day (pd) 21 to pd 50 adolescent female Wistar rats were either reared with same-strain partners (control) or within a group of Fischer 344 rats (inadequate social rearing, ISR), previously shown to serve as inadequate play partners for the Wistar strain. Adult ISR animals showed pronounced deficits in social interaction, social memory, processing of socially transmitted information, and decreased pain sensitivity. Molecular analysis revealed increased CB1 receptor (CB1R) protein levels and CP55, 940 stimulated
SGTPγS binding activity specifically in the amygdala and thalamus in previously peer-rejected rats. Along with these changes, increased levels of the eCB anandamide (AEA) and a corresponding decrease of its degrading enzyme fatty acid amide hydrolase (FAAH) were seen in the amygdala. Our data indicate lasting consequences in social behavior and pain sensitivity following peer-rejection in adolescent female rats. These behavioral impairments are accompanied by persistent alterations in CB1R signaling. Finally, we provide a novel translational approach to characterize neurobiological processes underlying social peer-rejection in adolescence.

Borderline personality disorder is characterised by a pervasive pattern of instability in affect regulation, impulse control, interpersonal relationships, and self-image. Clinical signs of the ...disorder include emotional dysregulation, impulsive aggression, repeated self-injury, and chronic suicidal tendencies, which make these patients frequent users of mental-health resources. Causal factors are only partly known, but genetic factors and adverse events during childhood, such as physical and sexual abuse, contribute to the development of the disorder. Dialectical behaviour therapy and psychodynamic partial hospital programmes are effective treatments for out-of-control patients, and drug therapy can reduce depression, anxiety, and impulsive aggression. More research is needed for the understanding and management of this disabling clinical condition. Current strategies are focusing on the neurobiological underpinnings of the disorder and the development and dissemination of better and more cost-effective treatments to clinicians.
Background
Evidence from randomized controlled trials is growing that exercise interventions are beneficial in cancer patients receiving allogeneic stem cell transplantation (allo-HCT). However, ...information about adherence to exercise interventions and exercise contamination in control groups is lacking. This information is crucial for the interpretation of study results. We therefore examined the determinants of exercise adherence and contamination in different treatment periods during (inpatient) and after (outpatient) allo-HCT.
Methods
One hundred fifty-three patients scheduled for allo-HCT were randomized to a 1-year partly supervised exercise intervention (endurance and resistance exercise) or to a control group. Adherence was assessed via exercise logs and contamination via questionnaires.
Results
Adherence varied between 66 % (inpatient) and 78 % (outpatient) in different treatment periods. During (inpatient) transplantation period, higher adherence was significantly associated with lower fatigue (
P
= 0.004) and with having children at home (
P
= 0.049). Adherence after discharge was positively associated with endurance performance (
P
= 0.003); higher adherence after day 100 was associated with exercise activity prior allo-HCT (
P
= 0.010) and higher adherence after discharge (
P
= 0.001). Contamination among controls was high with 54 % and significantly associated with muscle strength (
P
= 0.025) and fatigue (
P
= 0.050).
Conclusion
Exercise adherence in different treatment periods was determined by different variables, and contamination among controls was evident. These findings may have important implications for correct interpretation of randomized exercise intervention trials.
Background Borderline personality disorder (BPD) is characterized by a negative perception of others. Previous studies have revealed deficits and biases in facial emotion recognition. This study ...investigates the behavioural and electrophysiological correlates underlying facial emotion processing in individuals with BPD. Methods The present study was conducted between July 2012 and May 2014. In an emotion classification task, unmedicated female patients with BPD as well as healthy women had to classify faces displaying blends of anger and happiness while the electroencephalogram was recorded. We analyzed visual event-related potentials (ERPs) reflecting early (P100), structural (N170) and categorical (P300) facial processing in addition to behavioural responses. Results We included 36 women with BPD and 29 controls in our analysis. Patients with BPD were more likely than controls to classify predominantly happy faces as angry. Independent of facial emotion, women with BPD showed enhanced early occipital P100 amplitudes. Additionally, temporo-occipital N170 amplitudes were reduced at right hemispherical electrode sites. Centroparietal P300 amplitudes were reduced particularly for predominantly happy faces and increased for highly angry faces in women with BPD, whereas in healthy volunteers this component was modulated by both angry and happy facial affect. Limitations Our sample included only women, and no clinical control group was investigated. Conclusion Our findings suggest reduced thresholds for facial anger and deficits in the discrimination of facial happiness in individuals with BPD. This biased perception is associated with alterations in very early visual as well as deficient structural and categorical processing of faces. The current data could help to explain the negative perception of others that may be related to the patients’ impairments in interpersonal functioning.
Background Neurobiological findings and clinical data suggest that dissociative experience inhibits conditioning processes, but experimental studies are lacking. The aim of our study was to determine ...whether high states of dissociative experience would specifically alter emotional learning, but not declarative knowledge. Methods We used an aversive differential delay conditioning procedure in 33 unmedicated patients with borderline personality disorder (BPD) and 35 healthy controls. Results Patients with BPD who had high state dissociative experiences (BPD D +) showed diminished acquisition of differential aversive delay conditioning with respect to emotional learning compared with those who did not experience dissociative symptoms (BPD D–) and healthy controls (skin conductance response; interaction dissociation × quadratic time × type, p = 0.009). Specifically, the control group and the BPD D– subgroup showed an increase in valence and arousal to the conditioned stimulus (CS +) during the conditioning procedure (all p < 0.012) and demonstrated differential skin conductance responses in the acquisition and extinction phases. In contrast, the BPD D + subgroup showed no increase in valence and arousal to CS + or differential response regarding skin conductance. We examined general psychopathology, trauma history, perceptual differences and posttraumatic stress disorder as confounding factors, but we found no evidence of bias. Limitations Subdividing the BPD group reduced power. In addition, because our sample included only women, the generalizability of our results is constrained. Furthermore, we performed no separate analysis of the influence of different aspects of dissociation on the learning process. Conclusion Emotional, amygdala-based learning processes seem to be inhibited during state dissociative experience. State dissociative experience may alter acquisition and extinction processes and should be closely monitored in exposure-based psychotherapy.
