Recent years brought considerable attention to the connection between chronic stress and the development of autoimmune diseases. However, little is still known about the impact of prolonged stress reactions on the onset and course of primary Sjögren Syndrome (pSS). This study aimed to seek for associations between chronic stress, resulting from stressful life events, and pSS. In the study, 50 patients with diagnosed pSS, as well as 50 control patients with osteoarthritis underwent an assessment. Modified Holmes-Rahe (H-R) stress scale was used in order to evaluate the impact of stressful events within 12 months prior to the diagnosis. Patients with pSS had a significantly higher total score on H-R stress scale within one-year preceding the disease diagnosis (152 ± 66.3 vs 50 ± 54.6; p $<$ 0.001). Additionally, the pSS patients more commonly than the controls reported a subjectively perceived correlation between stressful events and the occurrence of disease symptoms (50% vs 12%; p $<$ 0.001). Moreover, the H-R score at the time of the assessment correlated with the disease activity. The results support the view that pSS belongs to the group of diseases which pathogenesis is closely related to stressful life events. The novelty of this work lies in focus on both the correlation of stress on the onset of autoimmune disease as well as the activity of previously diagnosed disorder. Our data contributes to finding evidence-based medicine (EBM) arguments to what has until recently been merely a thematic observation-the harmfulness of negative stress on individual's health status.

Previous studies have shown that corticosterone rapidly alters extracellular serotonin (5-hydroxytryptamine; 5-HT) concentrations in the dorsomedial hypothalamus (DMH) of adult male rats, suggesting a role for corticosterone actions in the DMH in regulation of physiological and behavioral responses. Whether or not corticosterone also rapidly alters extracellular serotonin concentrations in the DMH of female rats, and the dependence of this effect on ovarian hormones, is not known. To determine the effects of 17β-estradiol (E₂), progesterone (P), and corticosterone on extracellular concentrations of serotonin in the DMH, corticosterone and/or P were delivered into the DMH of ovariectomized rats via reverse microdialysis in E₂-primed rats. Combined, but not separate, delivery of corticosterone and P into the DMH rapidly and transiently increased extracellular 5-HT concentrations, a result that was dependent upon circulating E₂. This effect of corticosterone on DMH 5-HT was replicated by local perfusion of the organic cation transporter 3 (OCT3) competitive inhibitor normetanephrine. Intra-DMH infusions of either corticosterone or normetanephrine also reversibly suppressed lordosis responses in E₂ + P-primed females. These results suggest that ovarian hormones in combination with corticosterone modulate OCT3-mediated 5-HT clearance in the DMH, potentially representing an adaptive mechanism that allows sexually receptive females to respond rapidly to acute stressors.

Domestic violence remains a complex and challenging issue, particularly for professionals engaged in providing support to victims. The occurrence of emergency situations, such as the COVID-19 pandemic, further exacerbates the difficulties faced by these practitioners. This study aims to explore the lived experiences of professionals working with domestic violence victims, with a specific focus on the primary challenges encountered during interventions. It also aims to identify key guidelines that could enhance their practices. Twenty-four professionals from the domestic violence victim support in Portugal participated in this qualitative research. Through semi-structured interviews and thematic analysis, the study identified a range of challenges professionals confront in their intervention efforts. These challenges encompassed various aspects of the intervention process, vulnerabilities observed in victims, and the existing support system. Furthermore, the study uncovered specific challenges posed by the COVID-19 pandemic. Alongside these challenges, the research highlighted a set of recommendations designed to refine intervention strategies and promote better professional adaptation. The findings underscore the array of challenges that professionals grapple with, impacting both their strategies for intervention and their overall well-being. Thus, the development of effective intervention methodologies for professionals and organizations emerges as a crucial endeavor, essential for assisting domestic violence victims in their daily lives and enhancing preparedness for potential future crises.

Despite the overall desirability of men's upper body strength, women's preference for such features remains bounded to contexts in which the benefits exceed the potential costs. The relative salience of these costs could be augmented within ostensibly threatening environments, which could include one of ambient darkness. This study sought to determine whether women's interest in strong men would become downregulated in the presence of these cues. A sample of sorority women reported their reactions to meeting a hypothetical man on campus who was manipulated to appear either strong or weak with the image manipulated to be either at night or during the day. Although women reported feeling more comfortable around the weak man in the dark compared to the strong man, no difference emerged in their evaluations of strong men during the day and night. These findings suggest that women functionally shift their interest in strong men based on environmental cues that could implicate men as costly.

Previous research has shown there is a high prevalence of sexual violence (SV) and revictimization among the LGBTQ+ community. Little is known about the prevalence of SV and revictimization among rural LGBTQ+ individuals. This study investigates patterns of revictimization and the prevalence of SV among sexual and gender minority individuals. Less resources, services, and more social isolation in rural areas may exacerbate SV. The Illinois Cohort Study is a longitudinal cohort made up of LGBTQ+ individuals with recruitment from June to September 2022. Individuals that have met the screening criteria were delivered a series of surveys for completion, after obtaining consent and given an incentive for their participation. Survey questions on intimate partner violence, sexual assault, and revictimization were collected and described using descriptive statistics. Rural areas were defined as having a population less than 50,000. A total of N = 74 participants responded to the third survey. There were 46% of participants who identified as non-cisgender, and roughly 48% of participants identified as bisexual, pansexual, or other. There were 58% of participants who experienced some form of SV. Factors significantly associated with SV included age, gender, and total Adverse Childhood Experience score (p < .001, .0278, and .002, respectively). There were 70% of participants who reported experiencing SV more than once. Those who reported being sexually victimized more than once reported the abuse lasting an average of 11 years. There were 46% of participants who felt unsafe or trapped in their current relationship. Lesbian (31%) or bisexual (31%) participants were significantly more likely to report feeling afraid in their relationship (p = .041). This study showed that in rural areas, SV is prevalent among LGBTQ+ individuals. Data can be used to produce interventions and resources to reduce the prevalence of SV and revictimization among rural LGBTQ+ individuals.

Rape myth acceptance (RMA) is the acceptance of false beliefs, stereotypes, and statements about rape victims, perpetrators, and the act itself. RMA positively predicts shame felt by victims and negatively predicts reports of sexual victimization. Knowledge about sexual violence changes over time; accordingly, psychometric scales measuring RMA should be updated. Hahnel-Peeters and Goetz developed the Rape Excusing Attitudes and Language (REAL) scale by updating the Illinois RMA Scale-a major instrument used in the United States. However, the REAL scale is not available in Japanese. Therefore, we developed and validated a Japanese version of the REAL scale, evaluated RMA in Japanese individuals (N = 1,000), and compared the Japanese participants' RMA levels with the mean participant scores from Hahnel-Peeters and Goetz. In collaboration with one of the original authors, the Japanese version was developed through a back-translation process and administered to 1,000 men and women aged between 18 and 65; exploratory and confirmatory factor analyses were conducted on the data collected. The confirmatory factor analysis showed that the Japanese version moderately fitted the 4-factor structure of the original REAL scale. However, a 2-factor form obtained in the exploratory factor analysis best fit the data. Consistent with the original version, the Japanese version showed higher RMA in men than in women. The young generation (18-29 years old) self-reported higher RMA than other generations. Japan's RMA was significantly higher than that of the U.S. sample. The Japanese version of the REAL scale can be used in future studies to assess RMA in Japanese individuals and develop suitable educational programs to reduce RMA.

Exposure to potentially morally injurious events (PMIEs) among combat veterans has been acknowledged as a significant stressful combat event that may lead to various mental health problems, including depression and moral injury (MI), outcomes of shame and guilt. Recent studies have examined both risk and protective factors that can contribute to PMIEs and their consequences. However, while the general level of one's moral judgment is a logical contributor to moral injuries, it has yet to be examined empirically. In the current study, we examined the unique impact of moral judgment levels on the experience of PMIEs among combat veterans. We also examined the moderating role of moral judgment in the relationship between PMIEs and MI outcomes and depressive symptoms. A volunteer sample of 70 male Israeli combat veterans completed self-report questionnaires and a moral judgment task in a cross-sectional design study. Our findings indicate that moral judgment contributed to higher levels of perceiving others' actions as transgressive (PMIE-Other), above and beyond combat exposure. Moreover, we found that moral judgment has a moderating role in the link between PMIEs and their negative outcomes: Among veterans with higher levels of moral judgment, the association between PMIEs and their expressions was stronger than for those with lower levels of moral judgment. Our finding highlights the unique contribution of moral judgment level to PMIEs and their mental health consequences. It can be cautiously suggested that moral judgment should be viewed as a pre-recruitment risk factor that can help identify those at greater risk for mental health problems following exposure to PMIEs.

Despite the importance of adaptability for new product development team performance, empirical research that explores the factors promoting their adaptive capacity is limited. This study draws from psychological resource theories to examine how and under which conditions team psychological capital enhances the adaptivity of new product development teams. Data were collected from 198 student teams who took part in a project management simulation. Results showed that the positive relationship between team PsyCap and team adaptivity travels through team creativity and that the level of outcome focus moderates the first stage of this relationship.

The current studies addressed the associations between attachment representations with parents and a single best friend, intimacy behaviors (self-disclosure and support-seeking), and friendship quality in emerging adulthood, using the actor-partner interdependence mediation model (APIMeM). Study 1 (N = 186 dyads) examined whether attachment to parents predicted friendship quality, and whether this was mediated by attachment to their best friend. More avoidance or anxiety with parents predicted lower friendship quality, which was mediated by avoidance or anxiety with their best friend. Study 2 (N = 118 dyads) examined whether self-disclosure and support-seeking mediated the link between attachment with best friend and friendship quality. Anxiety with their best friend predicted lower friendship quality, which was mediated by support-seeking. Anxiety predicted less self-disclosure and support-seeking. We found no effects of avoidance. No partner effects were found in both studies. The findings are discussed in terms of adult attachment theory.

Veterans who are unemployed and living with mental health or substance use conditions are in need of integrative interventions that support their career development, mental wellness, and sobriety. However, career development interventions are often developed and implemented separate from mental health services. This paper introduces a novel intervention that supports career development of veterans with mental health and substance use concerns: Purposeful Pathways. This paper presents the results from three phases of intervention development: (1) retreats with clinical and vocational psychology experts (n=13) to develop the theoretical mechanisms of Purposeful Pathways, (2) focus groups with Veterans Health Affairs vocational counselors (n=6) who provide employment services to veterans with mental health conditions, and (3) an open trial in which veterans with mental health conditions (n=10) received Purposeful Pathways and provided feedback. Descriptions of the iterative processes of developing the Purposeful Pathways intervention are presented as a model for developing vocational interventions.
