Thriving together: the benefits of women's social ties for physical, psychological and relationship health

Parenting behaviors and deviant peer affiliation among Chinese adolescents: the mediating role of psychological reactance and the moderating role of gender

Given the negative impact of deviant peer affiliation on adolescent behavioral development, understanding its underlying mechanisms is essential. Drawing on social development model, psychological reactance theory and adolescent-limited delinquency theory, this study examined the relationship between parenting behaviors and adolescents' deviant peer affiliation, as well as the mediating role of reactance and the moderating role of gender. The research involved 1,822 high school students (Mage = 15.28 years, SDage = 2.40) from two provinces in China. All students completed a face-to-face questionnaire administered in a computer room at their respective school. This study found that parental emotional warmth was negatively correlated with adolescent deviant peer affiliation. On the contrary, parental rejection and overprotection were positively correlated with adolescent deviant peer affiliation. Furthermore, the findings indicated that reactance significantly mediated the relationship between parental emotional warmth, rejection, overprotection, and deviant peer affiliation, with reactance fully mediating the relationship between parental overprotection and deviant peer affiliation. Finally, the gender of the adolescent was found to significantly moderate the relationship between parental rejection (β = -0.10, p =.04), emotional warmth (β = 0.16, p =.003) and deviant peer affiliation, although no moderation was observed regarding parental overprotection. These results suggest that various parenting behaviors employ complex mechanisms to influence adolescents' deviant peer affiliation, with reactance and gender differences playing pivotal roles. This study offers new insights into the mechanisms underlying adolescent deviant peer affiliation and underscores the importance of reducing deviant peer affiliation through interventions targeting reactance and parenting behaviors.

Gender difference in prevalence and network structure of subclinical Hikikomori and depression among college students

BACKGROUND

Subclinical Hikikomori and depression are common among college students, yet gender differences in their prevalence and interrelationships are under-explored. This study evaluated gender differences in prevalence and symptom networks of these disturbances.

METHODS

A large-scale, multi-center study was conducted across Xinjiang, Qinghai, and Guangdong provinces, China between September and December 2023. Subclinical Hikikomori and depression were assessed with the 1-month 25-item Hikikomori Questionnaire (HQ-25M) and the Patient Health Questionnaire-9 (PHQ-9), respectively. Gender differences in prevalence were tested with univariate analyses, while network analyses assessed symptom structures within each gender. Expected Influence (EI) identified the most central symptoms, with higher EI indicating greater impact. Bridge EI identified specific symptoms that linked Hikikomori and depression symptom communities.

RESULTS

Among 6,222 college students, no significant gender differences were found in the prevalence of subclinical Hikikomori (males: 11.4% and females: 13.3%) or depression (males: 19.1% and females: 18.3%). Network analysis revealed 'I avoid talking with other people' (HQ18) as the most central symptom for both males (EI = 1.60) and females (EI = 1.73), followed by 'It is hard for me to join in groups' (HQ13, EI = 1.442) and 'I have little contact with other people' (HQ19, EI = 1.437) in males, and followed by 'Loss of energy' (PHQ4, EI = 1.17) and 'I have little contact with other people' (HQ19, EI = 1.09) in females. The key bridge symptoms were identified as 'Guilt feelings' (PHQ6) for males (Bridge EI = 0.14) and 'Suicidal ideation' (PHQ9) for females (Bridge EI = 0.13). Significant overall gender differences in networks were observed (M = 0.12, p = .01).

CONCLUSION

Depression and subclinical Hikikomori are common among Chinese college students although we observed no significant gender differences in its prevalence. The most influential central and bridge symptoms from network models are viable targets for intervention for both genders.

Gender, Adverse Changes in Social Engagement and Risk of Unhealthy Eating: A Prospective Cohort Study of the Canadian Longitudinal Study on Aging (2011-2021)

BACKGROUND

Social isolation is linked to survival and health. However, dietary effects of social activities, and gender differences, over time are unknown.

METHODS

A prospective study of adults (45+y) reporting daily fruit or vegetable (F/V) intake (at wave 1) from the Canadian Longitudinal Study on Aging (CLSA). Multivariable mixed logistic regression assessed changes in social isolation or breadth of social participation (wave 1 to 2) in relation to adverse changes in F/V (non-daily intake) at wave 3 in women and men.

RESULTS

Women who remained socially isolated between waves 1 and 2 had 85% higher odds of non-daily vegetable intake (OR 1.85 [95% CI: 1.32, 2.59]) and over twofold higher odds of non-daily fruit intake (2.23 [1.58, 3.14]), compared to reference (not isolated at waves 1 and 2). Higher odds of non-daily F/V intake were also observed for women who changed from isolated at wave 1 to not isolated at wave 2. Women and men who had less diverse social participation at waves 1 and 2 had 28-64% higher odds of non-daily F/V intake, compared to their counterparts with diverse social participation at both waves. Higher odds of non-daily fruit were also seen for women who had diverse social participation at wave 1 but reduced their diversity at wave 2 (1.35 [1.12, 1.62]).

CONCLUSIONS

Results showed persistent social isolation impacted changes in F/V among women only, while limited breadth of social participation affected F/V intake in both genders. Further longitudinal research on the complexities of social engagement and eating behavior is warranted.

Sexually dimorphic dopaminergic circuits determine sex preference

Sociosexual preference is critical for reproduction and survival. However, neural mechanisms encoding social decisions on sex preference remain unclear. In this study, we show that both male and female mice exhibit female preference but shift to male preference when facing survival threats; their preference is mediated by the dimorphic changes in the excitability of ventral tegmental area dopaminergic (VTADA) neurons. In males, VTADA projections to the nucleus accumbens (NAc) mediate female preference, and those to the medial preoptic area mediate male preference. In females, firing-pattern (phasic-like versus tonic-like) alteration of the VTADA-NAc projection determines sociosexual preferences. These findings define VTADA neurons as a key node for social decision-making and reveal the sexually dimorphic DA circuit mechanisms underlying sociosexual preference.

Empathy, Theory of Mind, and psychological outcomes in early parenthood: comparing mothers, fathers, and non-parents

AIMS/BACKGROUND

Parenthood may influence social cognitive processes such as Theory of Mind (ToM) and empathy, which are linked to parental psychological well-being. However, there is limited research on these relationship in the early postpartum period (6-12 months post-birth). This study explores differences in ToM and empathy in parents of young infants compared to non-parents and examines how these traits relate to parents' psychological well-being, attachment, and caregiving attitudes.

DESIGN/METHODS

A sample of 209 parents (53 mothers, 56 fathers) of infants aged 6-12 months and 100 non-parents completed the Interpersonal Reactivity Index (IRI) for empathy and the Reading the Mind in the Eyes Test (RMET) for ToM. Measures of parents' stress and psychological distress were also included.

RESULTS

Parents demonstrated higher empathic concern compared to non-parent men, with no differences in ToM. Subgroup analyses revealed distinct patterns in how empathy and ToM related to attachment, caregiving attitudes, and well-being, with empathic concern linked to lower stress in mothers and personal distress associated with poorer well-being in fathers.

CONCLUSION

The findings underscore empathy's relevance to parental mental health and caregiving, suggesting avenues for targeted mental health interventions. Future research should employ experimental and longitudinal designs to expand on these findings.

Sex Differences in Subclinical Psychotic Experiences: The Role of Daily-Life Social Interactions

BACKGROUND AND HYPOTHESIS

Sex differences in psychosis are reported across the psychosis spectrum, including in subclinical stages. An important factor in understanding these variations is the subjective experience of everyday social interactions (SI). We investigated whether the presence of psychotic experiences (PEs), as well as associated distress, differs between men and women. We focused on the role of daily-life SI quality and whether its association with PEs varies by sex.

STUDY DESIGN

We included adolescents from SIGMA, a general youth population study in Flanders, Belgium (n = 344; mean age = 18.7; 63.4% female). Psychotic experiences were measured using the PQ-16. We used Experience Sampling Methodology to assess daily-life SI. A multilevel model and multiple linear regressions were used to assess, respectively, the relationship between sex and SI quality and whether PEs and their association with SI quality differ between young men and women.

STUDY RESULTS

The results of the multilevel linear regression model indicate that the prevalence of and distress associated with PEs were higher in women. No significant difference was observed in the subjective quality of daily SI. Social interaction quality was strongly related to PEs. This association did not seem to vary for the prevalence of PEs, though women's distress about PEs appeared to be more affected by SI quality.

CONCLUSIONS

Present findings highlight the role of the subjective quality of SI in subclinical psychosis. More research is needed to investigate the mechanisms through which SI quality relates to PEs, and whether these differ between young men and women.

Behavioral and neural responses to social exclusion in women: the role of facial attractiveness and friendliness

The behavioral and neural responses to social exclusion were examined in women randomized to four conditions, varying in levels of attractiveness and friendliness. Informed by evolutionary theory, we predicted that being socially excluded by attractive unfriendly women would be more distressing than being excluded by unattractive women, irrespective of their friendliness level. Our results contradicted most of our predictions but provide important insights into women's responses to interpersonal conflict. Accounting for rejection sensitivity, P300 event-related potential amplitudes were largest when women were excluded by unattractive unfriendly women. This may be due to an expectancy violation or an annoyance with being excluded by women low on social desirability. An examination of anger rumination rates by condition suggests the latter. Only attractive women's attractiveness ratings were lowered in the unfriendly condition, indicating they were specifically punished for their exclusionary behavior. Women were more likely to select attractive women to compete against with one exception-they selected the Black attractive opponent less often than the White attractive opponent when presented as unfriendly. Finally, consistent with studies on retaliation in relation to social exclusion, women tended to rate competitors who rejected them as being more rude, more competitive, less attractive, less nice, and less happy than non-competitors. The ubiquity of social exclusion and its pointed emotional and physiological impact on women demands more research on this topic.

Association of childhood trauma, social support, cognition, and suicidality in females with bipolar disorder

BACKGROUND

Bipolar disorder (BD) is a severe mental disorder with heavy disease burden. Females with BD are special populations who suffer a lot from childhood trauma, social support, cognitive deficits, and suicidality. In this study, the relationship among childhood trauma, social support, and clinical symptoms of BD was investigated and the risk factors for suicidality were explored in female patients with BD.

METHODS

This study included 57 drug-naive female BD patients, 64 female BD patients with long-term medication, and 50 age-matched female healthy controls. Childhood trauma, social support, clinical symptoms, cognition, and suicidality (suicide ideation, suicide plan, suicide attempt, suicide frequency) were measured with scales.

RESULTS

Compared with healthy controls, females with BD showed higher levels of childhood trauma and suicidality, and lower levels of social support and cognitive deficits. In the drug-naïve BD group, social support mediated the relationship between childhood trauma and insomnia symptoms (indirect effect: ab = 0.025). In the BD with long-term medication group, mania symptom was associated with suicide plan (OR = 1.127, p = 0.030), childhood trauma was associated with suicide attempt (OR = 1.088, p = 0.018), and years of education (OR = 0.773, p = 0.028), childhood trauma (OR = 1.059, p = 0.009), and delayed memory (OR= 1.091, p= 0.016) was associated with suicide frequency (OR = 1.091, p = 0.016).

CONCLUSIONS

This study provides initial evidence that social support partially explains the relationship between childhood trauma and clinical symptoms in females with BD. Additionally, mania symptoms, childhood trauma, and delayed memory were risk factors for suicidality. Interventions providing social support and improving cognitive function may be beneficial for females with BD who are exposed to childhood trauma and with high suicide risk.

Gender moderates the association between resting vagally mediated heart rate variability and attentional control

Background

Women typically exhibit weaker attentional control ability than men. Lower resting vagally mediated heart rate variability (vmHRV) is thought to reflect the poorer function of the neurophysiological pathways underlying attentional control and thus, poorer attentional control ability. However, existing findings are inconsistent regarding the relationship between vmHRV and attentional control. Gender may be an important moderator.

Objective

To examine whether gender moderates the relationship between resting vmHRV and attentional control, and to provide neurophysiological evidence for elucidating gender differences in attentional control ability.

Methods

Two hundred and twenty college students completed the Attentional Control Scale to evaluate their attentional control ability. Resting vmHRV was assessed during a 5 min baseline period using an electrocardiographic amplifier (ECG100C) of the Biopac MP150 physiological recorder.

Results

(1) There was no significant difference in the total scores of the Attentional Control Scale between men and women (t = 0.498, p > 0.05), but the scores of the attentional shifting dimension of women were significantly lower than those of men (t = 1.995, p < 0.05); (2) Resting vmHRV was significantly negatively correlated with attentional control in women(r = -0.233, p < 0.01), whereas the correlation was not significant in men; (3) Gender significantly moderated the relationship between resting vmHRV and attentional control (B = -3.088, 95% boot CI [-5.431, -0.745], t = -2.598, p < 0.05); (4) Among participants with lower resting vmHRV, there was no significant difference in attentional control between men and women (B = 2.284, 95% boot CI [-0.748, 5.310], p > 0.05), but among participants with higher resting vmHRV, men scored significantly higher than women in attentional control (B = -3.377, 95% boot CI [-6.406, -0.348], p < 0.05).

Conclusion

Gender moderates the relationship between resting vmHRV and attentional control, with higher resting vmHRV in women reflecting a compensatory response to deficits in attentional control.

Differential network interactions between psychosocial factors, mental health, and health-related quality of life in women and men

Psychosocial factors affect mental health and health-related quality of life (HRQL) in a complex manner, yet gender differences in these interactions remain poorly understood. We investigated whether psychosocial factors such as social support and personal and work-related concerns impact mental health and HRQL differentially in women and men during the first year of the COVID-19 pandemic. Between June and October 2020, the first part of a COVID-19-specific program was conducted within the "Characteristics and Course of Heart Failure Stages A-B and Determinants of Progression (STAAB)" cohort study, a representative age- and gender-stratified sample of the general population of Würzburg, Germany. Using psychometric networks, we first established the complex relations between personal social support, personal and work-related concerns, and their interactions with anxiety, depression, and HRQL. Second, we tested for gender differences by comparing expected influence, edge weight differences, and stability of the networks. The network comparison revealed a significant difference in the overall network structure. The male (N = 1370) but not the female network (N = 1520) showed a positive link between work-related concern and anxiety. In both networks, anxiety was the most central variable. These findings provide further evidence that the complex interplay of psychosocial factors with mental health and HRQL decisively depends on gender. Our results are relevant for the development of gender-specific interventions to increase resilience in times of pandemic crisis.
