Introduction: This meta-analysis examined the association between dimensional and categorical conceptualizations of attachment styles and suicidal thoughts and behaviors (STBs). Methods: Random-effects meta-analysis was conducted to examine the associations between categorical secure attachment, categorical insecure attachment, and insecure attachment dimensions and STBs. Methodological moderators were also explored. This protocol was registered in PROSPERO (CRD42020152604). Results: Systematic search for articles published by December 2020 returned 58 eligible studies and 159 cross-sectional effects. Secure attachment was inversely associated with suicidal thoughts and not associated with suicide attempts. All categorical insecure attachment styles were positively associated with suicidal thoughts. Only fearful and preoccupied attachment were associated with risk for suicide attempts. Dimensional attachment anxiety was more strongly associated with suicidal thoughts and attempts than dimensional attachment avoidance. Discussion: Overall, attachment styles characterized by high attachment anxiety were associated with greatest vulnerability to STBs. Longitudinal studies are needed to better understand the association between attachment insecurity and STBs. [ABSTRACT FROM AUTHOR]

Introduction: This study examined daily fluctuations in the unmet interpersonal needs of thwarted belongingness and perceived burdensomeness in response to daily negative social interactions, as well as the moderating role of respiratory sinus arrhythmia (RSA) across adolescents at lower and higher risk for suicidal ideation. Methods: Fifty five adolescents with major depressive disorder (MDD, i.e., higher‐risk group) and without MDD (i.e., lower‐risk group) completed measures of resting RSA, and daily measures of negative social interactions, perceived burdensomeness, and loneliness, as a proxy for thwarted belongingness, for 10 consecutive days. Within‐person analyses examined the association between daily negative social interactions and unmet interpersonal needs, and the moderating roles of RSA and higher‐risk group status. Between‐person analyses also examined the association between RSA and unmet interpersonal needs across groups. Results: At the within‐person level, participants reported more unmet interpersonal needs on days when they reported more negative social interactions. At the between‐person level, higher RSA was associated with decreased loneliness in both groups, and decreased burdensomeness among the higher‐risk group. Conclusions: Negative social interactions are associated with daily unmet interpersonal needs. Higher RSA may serve as a protective factor mitigating risk for unmet interpersonal needs, particularly burdensomeness, among adolescents at higher risk for suicidal ideation. [ABSTRACT FROM AUTHOR]

Brooding rumination is an intrapersonal emotion regulation strategy associated with negative interpersonal consequences. Resting respiratory sinus arrhythmia (RSA), a psychophysiological marker of self-regulatory capacity, may buffer the association between maladaptive emotion regulation and negative interpersonal behaviors. The current work examines the moderating effect of RSA on the association between brooding rumination and different negative interpersonal consequences. Across three convenience samples, individuals with lower RSA showed a stronger association between brooding rumination and more negative interpersonal behaviors as well as less perception of received instrumental social support (Study 1; n = 154), higher levels of interviewer-rated interpersonal stress (Study 2; n = 42) and a stronger indirect association between brooding rumination and depressive symptoms via daily interpersonal stress (Study 3; n = 222). These findings highlight the negative interpersonal consequences of brooding rumination, particularly among individuals with lower RSA. [ABSTRACT FROM AUTHOR]

Objective: This study sought to identify psychosocial predictors of trajectories of adherence to physical distancing alongside changes in public health measures during the COVID-19 pandemic. Design: A three-time point longitudinal survey during the first two waves of the COVID-19 pandemic. Methods: Participants (N = 1003) completed self-report measures of adherence to physical distancing over an 8-month period at the start (T1) and end (T2) of the first wave of the pandemic, and the start of the second wave of the pandemic (T3). Participants also completed measures of their health beliefs related to the self and others, social norms, emotional distress, and sociodemographic characteristics. Results: Using group-based trajectory modeling, four trajectories of adherence to physical distancing emerged: a high-adherence trajectory, a slow-declining trajectory, a fluctuating trajectory, and a fast-declining trajectory. The most important psychosocial predictors of poorer adherence trajectories included perceptions of lower self-efficacy and higher barriers to adherence, as well as lower prosocial attitudes towards physical distancing. Conclusion: Public health messages targeting these factors may be most relevant to promote sustained adherence to physical distancing over time in the context of a pandemic. [ABSTRACT FROM AUTHOR]

Stress exposure increases risk for depressive symptoms. However, there are substantial individual differences in affective responses to stress. High-frequency heart rate variability (HF-HRV), a marker of vagally-mediated parasympathetic activity, has been conceptualized as a psychophysiological index of emotion regulation that may moderate individuals' responses to stress. Using a daily diary design, we tested whether individual differences in resting HF-HRV moderated the association between daily child-related stress and negative affect among a sample of 84 heterosexual couples with preschool-aged children. After controlling for participants' age, gender, socioeconomic status, employment status, and ethnicity, hierarchical linear modeling revealed that resting HF-HRV moderated both the between-person and within-person associations between self-reported child-related stress and daily negative affect. Between-person analyses indicated that the strength of the positive association between mean daily child stress and negative affect across the daily diary period increased with decreasing resting HF-HRV. Similarly, within-person analyses indicated that on days when participants reported more child-related stress than usual, the magnitude of the increase in negative affect on that day was inversely related to resting HF-HRV. Taken together, these findings suggest that lower resting HF-HRV may index vulnerability to stress-related disturbances in negative affect. This increased negative affective response to daily stress may be one pathway through which individuals with lower resting HF-HRV are at increased risk for depressive symptoms over time. • Low heart rate variability (HRV) is related to affective reactivity to daily stress. • HRV moderates the between -person associations between stress and negative affect. • HRV moderates the within -person associations between stress and negative affect.

Attachment style may influence the acculturation process by shaping the types of social relationships that individuals form and maintain. Social relationship quantity and quality have been linked to chronic low-grade systemic inflammation, an immune process associated with risk for age-related diseases. The goal of this study was to investigate whether attachment style moderates the change in systemic inflammation during the early phases of the acculturation process, a period associated with rapid changes in social functioning. In this 5-month longitudinal study, 58 new international students completed the Adult Attachment Scale and provided blood samples for C-reactive protein (CRP) analysis shortly after arrival in the host country as well as 2 and 5 months later. Results indicated that individuals with higher attachment anxiety experienced larger increases in CRP over time. During a period of rapid changes in social functioning, attachment anxiety promotes immune changes that may increase health risk over time. [ABSTRACT FROM AUTHOR]

Objective: Trends in rates of adolescent suicide and undetermined deaths in Canada from 1981 to 2012 were examined, focusing specifically on variations between Canadian regions. Exploratory hypotheses were formulated for regional variability in adolescent suicide rates over time in Canada. Methods: A descriptive time trend analysis using public domain vital statistics data was performed. All deaths from 1981 to 2012 among 15 to 19 year olds coded as suicides or undetermined intent according to the International Classification of Diseases, 9th and 10th Revisions were included. Results: While there was an overall stability in adolescent suicide and undetermined death rates across Canada, regional analyses showed that Quebec experienced a 7.6% annual reduction between 2001 and 2012 while the Prairies and Atlantic provinces experienced significant annual increases since 2001. Ontario and British Columbia have had non-significant fluctuations since 2001. The trends remained similar overall when excluding undetermined deaths from the analyses. Conclusions: Variations in adolescent suicide trends across provinces were found. Factors such as provincial suicide action and prevention legislation contributing to these variations remain to be studied, but these regional differences point towards the need for better consistency of suicide prevention strategies across the country.

Background: High-frequency heart rate variability (HF-HRV) reactivity was proposed as a vulnerability factor for stress-induced sleep disturbances. Its effect may be amplified among individuals with high trait worry or sleep reactivity.Purpose: This study evaluated whether HF-HRV reactivity to a worry induction, sleep reactivity, and trait worry predict increases in sleep disturbances in response to academic stress, a naturalistic stressor.Method: A longitudinal study following 102 undergraduate students during an academic semester with well-defined periods of lower and higher academic stress was conducted. HF-HRV reactivity to a worry induction, trait worry using the Penn State Worry Questionnaire, and sleep reactivity using the Ford Insomnia Stress Reactivity Test were measured during the low stress period. Sleep disturbances using the Pittsburgh Sleep Quality Index were assessed twice during the lower stress period and three times during the higher stress period.Results: Greater reductions in HF-HRV in response to the worry induction predicted increases in sleep disturbances from the lower to the higher academic stress period. Trait worry moderated this association: individuals with both higher trait worry and greater HF-HRV reactivity to worry had larger increases in stress-related sleep disturbances over time, compared to participants with lower trait worry and HF-HRV reactivity. A similar, but marginally significant effect was found for sleep reactivity.Conclusion: This study supports the role of HF-HRV reactivity as a vulnerability factor for stress-induced sleep disturbances. The combination of high trait worry and high HF-HRV reactivity to worry might identify a subgroup of individuals most vulnerable to stress-related sleep disturbances. [ABSTRACT FROM AUTHOR]

Objective: A multi-informant approach is often used in child psychiatry. The Achenbach System of Empirically Based Assessment uses this approach, gathering parent reports on the Child Behaviour Checklist (CBCL) and youth reports on the Youth Self-Report (YSR), which contain scales assessing both the child's problems and competencies. Agreement between parent and youth perceptions of their competencies on these forms has not been studied to date. Method: Our study examined the parent-youth agreement of competencies on the CBCL and YSR from a sample of 258 parent-youth dyads referred to a specialized outpatient clinic for depressive and suicidal disorders. Intraclass correlation coefficients were calculated for all competency scales (activity, social, and academic), with further examinations based on youth's sex, age, and type of problem. Results: Weak-to-moderate parent-youth agreements were reported on the activities and social subscales. For the activities subscale, boys' ratings had a strong correlation with parents' ratings, while it was weak for girls. Also, agreement on activities and social subscales was stronger for dyads with the youth presenting externalizing instead of internalizing problems. Conclusion: Agreement on competencies between parents and adolescents varied based on competency and adolescent sex, age, and type of problem. [ABSTRACT FROM AUTHOR]

Close relationships are an important social context in which emotional experiences, regulation, and coregulation unfold. This interpersonal emotion regulation process is likely intertwined with the self-regulatory capacities and social skills of each individual dyad member. This study aimed to examine whether respiratory sinus arrhythmia (RSA), a physiological marker related to self-regulation, moderates the impact of rumination, a maladaptive emotion regulation strategy, on couples' conflict. A dyadic, longitudinal design examined the association among RSA, rumination, and couples' conflict in a sample of 83 cohabiting romantic partners raising young children. At baseline, rumination and RSA from each romantic partner were assessed. Couples' conflict was reported at 3 time points over the following 12 months. Actor-partner interdependence modeling examined the mutual contributions of each couple member's rumination to couples' conflict, as well as the moderating impact of RSA. Results indicated that rumination from both members of the dyad were independently associated with couples' conflict across the 12-month period. Furthermore, RSA moderated the association between one's partner's rumination and couples' conflict, such that high actor RSA attenuated the positive association between partner's rumination and couples' conflict. The findings highlight the interdependent nature of emotion regulation within close relationships, and the impact of RSA on interpersonal emotion regulation processes.

Respiratory sinus arrhythmia (RSA) has been conceptualized as a biomarker of a neurophysiological system supporting social behaviors. Capitalization, the interpersonal process of sharing positive experiences with close others, has been associated with improved intrapersonal and interpersonal functioning. The present study examined whether RSA moderated the within-person associations of daily capitalization with positive affect and relationship quality. Participants (N = 149) completed an electrocardiogram recording during a resting baseline and a worry induction period, as well as a 14-day daily diary assessment of capitalization, positive affect, and relationship quality. Results indicated that RSA reactivity moderated the within-person effects of daily capitalization on positive affect and relationship quality. On days when they did not capitalize, individuals with higher RSA reactivity experienced lower positive affect and poorer relationship quality than their counterparts with lower RSA reactivity. In contrast, no significant differences were observed between participants with lower and higher RSA reactivity on days when they capitalized. These results provide further evidence that RSA reactivity shapes sensitivity to social context, including one's responses to the lack of usual capitalization interactions. [ABSTRACT FROM AUTHOR]

Abstract: Background: To evaluate whether the Child Behavior Checklist Dysregulated Profile (CBCL-DP) can be used as an effective predictor of psychopathological severity as indicated by suicidality and comorbidities, as well as a predictor of pediatric bipolar disorder (PBD). Method: CBCL-DP scores for 397 youths seeking treatment for mood disorders were calculated by summing the t-scores of the Anxious/Depressed, Aggressive Behaviors, and Attention Problems subscales such that a clinical cut-off of 210 was used to indicate the presence of a dysregulated profile. Suicidality and an increased number of diagnoses were used as markers of illness severity. Results: Those with a dysregulated profile presented more severe suicidal ideation when compared to those without the profile. They also had a significantly larger number of Axis I diagnoses. Groups did not differ in the amount of individuals diagnosed with PBD. Limitations: Suicidal ideation was assessed by a third-party informant and not from the youths themselves. No other forms of suicidal behavior such as self-harm or suicide attempt were measured. Also there may not be complete convergence between parental reports on behavior and youth reports, which might have affected the results. Conclusions: These findings suggest that the CBCL-DP is an effective indicator of psychopathological severity through its association with more comorbidities and more severe suicidality. Earlier detection of psychopathological severity through an initial screening tool could aid clinicians in planning treatment and providing quicker and more structured care based on the client's needs.
