The biopsychosocial model of challenge and threat states specifies that these states engender different physiological and behavioural responses in potentially stressful situations. This model has received growing interest in the sport and performance psychology literature. The present systematic review examined whether a challenge state is associated with superior performance than a threat state. Across 38 published studies that conceptualised challenge and threat states in a manner congruent with the biopsychosocial model, support emerged for the performance benefits of a challenge state. There was, however, significant variation in the reviewed studies in terms of the measures of challenge and threat states, tasks, and research designs. The benefits of a challenge state on performance were largely consistent across studies using cognitive, physiological, and dichotomous challenge and threat measures, cognitive and behavioural tasks, and direct experimental, indirect experimental, correlational, and quasi-experimental designs. The results imply that sports coaches, company directors, and teachers might benefit from trying to promote a challenge state in their athletes, employees, and students, respectively. Future research could benefit from a greater consensus on how best to measure challenge and threat states to help synthesise the evidence across studies. Specifically, we recommend that researchers use both cognitive and physiological measures and develop stronger manipulations for experimental studies. Finally, future research should report sufficient information to enable risk of bias assessment.

In Poland, gender hierarchy restricting women's sexuality and hetero-normativity are rooted in traditional 'family values' supported by the teachings of the Polish Catholic Church and attached to Polish national identity. Dissenters to traditional norms regulating gender and sexual relations are rejected as threat to social order and national unity. Latent growth curve modeling performed on data from a three-wave longitudinal study indicated linear, interrelated increases in authoritarianism, a desire for national cohesion and rejection of sexual dissenters in the nationally representative sample of participants (N = 889) as the COVID-19 pandemic unfolded in Poland. Data were collected before and during the outbreak of the pandemic allowing us to link the changes in social attitudes to this naturally occurring threat. Cross-lagged panel analysis indicated that authoritarianism predicted desire for national cohesion, which resulted in rejection of dissenters. These results are in line with theoretical models of authoritarianism as a response to threat. They are also in line with findings linking death anxiety and the threat of infectious disease to increases in authoritarianism, traditional worldview defense, in-group cohesion and sexual restrictiveness.

Eye movement desensitization and reprocessing (EMDR) is a well-established treatment for post-traumatic stress disorder. Recent research suggested that it may be effective in treating depressive disorders as well. The present study is part of a multicenter randomized-controlled trial, the EDEN study, in which a homogenous group of 30 patients was treated to test whether EMDR plus treatment as usual (TAU) would achieve superior results compared to TAU only in a psychosomatic-psychotherapeutic inpatient treatment setting. Both groups were assessed by the Beck Depression Inventory-II (BDI-II) and the Global Severity Index and depression subscale of the Symptom Checklist 90-Revised. The EMDR + TAU group improved significantly better than the TAU group on the BDI-II and Global Severity Index, while a marginally significant difference favoring the EMDR + TAU group over the TAU group was found on the depression subscale. In the EMDR + TAU group, seven out of 14 patients improved below nine points on the BDI-II, which is considered to be a full remission, while four out of 16 in the TAU group did so. These findings confirm earlier suggestions that EMDR therapy may provide additional benefit in the treatment of depression. The present study strengthens the previous literature on EMDR therapy in the treatment of depression due to the randomized-controlled design of the EDEN study.

Background: The biopsychosocial model of challenge and threat specifies a challenge-threat continuum where favorable demand-resource evaluations, efficient cardiovascular responses, and superior performance characterize challenge; and maladaptive outcomes like clinical depression characterize threat states. The model also specifies task engagement, operationalized as heart rate and ventricular contractility increases, as a prerequisite for challenge and threat states. The blunted cardiovascular reactivity to stress literature describes reductions of these increases and associates them with problems like clinical depression. Objectives: To determine whether blunted cardiovascular reactivity to stress has implications for challenge and threat theory. Methods: We review and synthesize the literatures on blunted cardiovascular reactivity to stress and the biopsychosocial model. Results: Blunted cardiovascular reactivity appears not to reflect a physiological inability to respond to stress. Rather, it reflects a contextually dependent motivational dysregulation and reduced reactivity to stress consistent with deficient task engagement in the biopsychosocial model. Conclusion:We argue that blunted cardiovascular reactivity represents deficient task engagement, and more generally, motivational disengagement due to threat states. Our biopsychosocial model-based approach conceptualizes this motivational disengagement as a tendency to avoid motivated performance situations. This tendency may represent a defense mechanism against subsequent threat and might explain associations with disorders like clinical depression.

BackgroundDepression is a severe mental disorder that challenges mental health systems worldwide as the success rates of all established treatments are limited. Eye Movement Desensitization and Reprocessing (EMDR) therapy is a scientifically acknowledged psychotherapeutic treatment for PTSD. Given the recent research indicating that trauma and other adverse life experiences can be the basis of depression, the aim of this study was to determine the effectiveness of EMDR therapy with this disorder.MethodIn this study, we recruited a group of 16 patients with depressive episodes in an inpatient setting. These 16 patients were treated with EMDR therapy by reprocessing of memories related to stressful life events in addition to treatment as usual (TAU). They were compared to a group of 16 controls matched regarding diagnosis, degree of depression, sex, age and time of admission to hospital, which were receiving TAU only.ResultsSixty-eight percent of the patients in the EMDR group showed full remission at end of treatment. The EMDR group showed a greater reduction in depressive symptoms as measured by the SCL-90-R depression subscale. This difference was significant even when adjusted for duration of treatment. In a follow-up period of more than 1 year the EMDR group reported less problems related to depression and less relapses than the control group.ConclusionsEMDR therapy shows promise as an effective treatment for depressive disorders. Larger controlled studies are necessary to replicate our findings.
