Mindfulness and negative emotions among Chinese college students: chain mediation effect of rumination and resilience

Objective

This study examines the mediation effect of rumination and resilience between the relationship of mindfulness and negative emotions in Chinese college students.

Method

A total of 3,038 college students (19.94 ± 1.10) were investigated by Mindfulness Attention Awareness Scale (MASS), Rumination Response Style Scale (RRS), Resilience Scale (RES) and Depression-anxiety-pressure scale (DASS-21), and the mediation analyses were conducted by adopting PROCESS macro in the SPSS software.

Results

① Mindfulness was negatively associated with rumination and negative emotions (r = -0.69, -0.72; P < 0.01), and positively associated with resilience (r = 0.63, P < 0.01). Rumination was negatively associated with resilience (r = -0.59, P < 0.01), and positively associated with negative emotions (r = 0.83, P < 0.01). Resilience was negatively associated with negative emotions (r = -0.71, P < 0.01). ② Mindfulness can not only directly predict negative emotions (95%CI, -0.12~-0.09) but also affects negative emotions through three indirect paths: Rumination was a mediator (95%CI, -0.24~-0.20), resilience was a mediator (95%CI, -0.07~-0.06), and resilience and rumination were a chain mediator (95%CI, -0.04 ~ -0.03).

Conclusion

Mindfulness not only influences negative emotions directly, but also through the mediating effect of rumination and resilience indirectly.

Suicidality and Implicit Dependency in Child and Adolescent Inpatients With Histories of Trauma: Moderating Effect of Gender

ABSTRACT

There is lack of empirical findings on a direct link between suicidality and dependency in youth. This is particularly relevant for children and adolescents with a trauma history, since traumatization is a well-established risk factor for suicidality in this population. Research on dependency predominantly uses self-report assessments, which may be susceptible to biases. In this study, performance-based interpersonal dependency scores in inpatient children and adolescents with trauma history were compared with patients' suicidal behavior (suicidal ideation and suicidal attempts) as derived from chart records. The results showed a gender effect. High dependency scores were associated with higher suicidal ideation for girls and with lower suicidal attempts for boys. These findings demonstrate that a relationship between dependency and suicidality for hospitalized traumatized youth is impacted by gender.

Emotion Regulation Processes Can Benefit Self-Regulated Learning in Classical Musicians

Self-regulated learning (SRL) is the degree to which students are metacognitively, motivationally, and behaviourally active participants in their own learning process. It involves the self-regulation of cognitive, behavioural, and affective processes. SRL holds significant potential for enhancing practise and achievement. Although affect is acknowledged as one of the three fundamental processes in SRL, there is limited research investigating it. However, emotions have been found to influence SRL efficiency while emotion regulation (ER) can impact learning outcomes. Thus, this study sought to investigate how ER processes relate to SRL among professional musicians who perform Western classical music. Four forms of regulation (reappraisal, suppression, rumination, repression) were examined in relation to the SRL three-phase model. Professional musicians (N = 334) of 39 nationalities (age: 18–66; [M = 28]; female = 215; male = 119) completed a survey comprising the Self-Regulated Learning in Music Questionnaire, the Emotion Regulation Questionnaire, and demographic items. A significant positive correlation emerged between SRL and reappraisal, and significant negative correlations emerged between SRL and the other three processes. Further multiple linear regression analysis revealed that reappraisal, practise hours, and expertise accounted for 26% of the variance in SRL. Finally, a factorial (2 × 2 × 2) ANOVA yielded significant group differences on ER as a function of gender, expertise, and occupation. Results suggest that reappraisal can enhance the use of SRL in musicians, thus highlighting the potential utility in considering ER as part of SRL. These results suggest that by including training on emotion regulation strategies within musicians’ educational institutions and workplaces, efficiency and engagement in SRL can be enhanced. This could produce more effective learning strategies and outcomes, together with higher musical achievements.

The Influence of Negative Life Events on Suicidal Ideation in College Students: The Role of Rumination

This study aimed to investigate the influence of negative life events on suicidal ideation in college students and the role of rumination. Using a cluster sampling method, 894 college students were asked to fill out the adolescent life event scale, ruminative response scale, and suicidal ideation scale. The study revealed the following: (1) negative life events, rumination, and suicidal ideation were significantly positively correlated with each other; (2) rumination played a full mediating role in the influence of negative life events on suicidal ideation; and (3) rumination also played a moderating role in the influence of negative life events on suicidal ideation. Under a high level of rumination, negative life events had a significant positive effect on suicidal ideation in college students; however, under a low level of rumination, negative life events did not have a significant effect on suicidal ideation. Rumination played mediating and moderating roles in the relationship between negative life events and suicidal ideation among college students.

Masculine Traits and Depressive Symptoms in Older and Younger Men and Women

Evidence suggests that men who strongly endorse masculine traits display an atypical presentation of depression, including more externalizing symptoms (e.g., anger or substance use), but fewer typical, internalizing symptoms (e.g., depressed mood or crying). This phenomenon has not been adequately explored in older adults or women. The current study used the externalizing subscale of the Masculine Depression Scale in older and younger men and women to detect atypical symptoms. It was predicted that individuals who more strongly endorsed masculine traits would have higher scores on the measure of externalizing symptoms relative to a measure of typical depressive symptoms Center for Epidemiologic Studies-Depression Scale. It was anticipated that results would differ by age-group but not by gender. Multigroup path analysis was used to test the hypothesis. The hypothesized path model, in which endorsement of masculine traits was associated with lower scores on the Center for Epidemiologic Studies-Depression Scale and with scores on the externalizing, but not internalizing, factor of the Masculine Depression Scale, fit the data well. Results differed significantly by age-group and gender. Masculine individuals reported lower levels of typical depressive symptoms relative to externalizing symptoms, but further research is needed within age- and gender groups. Results are consistent with the gendered responding framework and suggest that current assessment tools, which tend to focus on internalizing symptoms of depression, may not detect depression in individuals who endorse masculine traits.

Neural systems underlying thought suppression in young women with, and at-risk, for depression

OBJECTIVE

Ruminative brooding is associated with increased vulnerability to major depression. Individuals who regularly ruminate will often try to reduce the frequency of their negative thoughts by actively suppressing them. We aimed to identify the neural correlates underlying thought suppression in at-risk and depressed individuals.

METHODS

Three groups of women were studied; a major depressive disorder group, an at-risk group (having a first degree relative with depression) and controls. Participants performed a mixed block-event fMRI paradigm involving thought suppression, free thought and motor control periods. Participants identified the re-emergence of "to-be-suppressed" thoughts with a button press.

RESULTS

During thought suppression the control group showed the greatest activation of the dorsolateral prefrontal cortex, followed by the at-risk, then depressed group. During the re-emergence of intrusive thoughts compared to successful re-suppression of those thoughts, the control group showed the greatest activation of the anterior cingulate cortices, followed by the at-risk, then depressed group.

CONCLUSIONS

At-risk participants displayed anomalies in the neural regulation of thought suppression resembling the dysregulation found in depressed individuals. The predictive value of these changes in the onset of depression remains to be determined.

Attachment and pain outcomes in adolescents: the mediating role of pain catastrophizing and anxiety

This study examined the relations between attachment styles and pain severity/depression in adolescents. Analyses examined whether anxiety and the 3 dimensions of pain catastrophizing mediated the associations between attachment styles, pain severity and depression. A total of 382 high-school students completed questionnaires assessing attachment styles, catastrophizing, depression, anxiety and, for those who reported pain during the last month, pain severity. Results revealed that secure attachment was associated with lower levels of pain severity, depression, pain catastrophizing and anxiety. Preoccupied and fearful attachment styles were associated with heightened pain severity, depression, pain catastrophizing and anxiety. Dismissing attachment style was only associated with high levels of depression and anxiety. Regression analyses revealed that anxiety and the helplessness dimension of pain catastrophizing mediated the relations between secure, preoccupied and fearful attachment styles and pain severity. Moreover, anxiety and the rumination dimension of pain catastrophizing mediated the relation between secure, preoccupied and fearful attachment styles and depression. These findings suggest that anxiety, pain catastrophizing and attachment styles are related processes but nevertheless make independent contributions to the prediction of pain severity and depression. In addition, these findings suggest that attachment styles and cognitive-affective factors might increase the risk of problematic outcomes in adolescents with pain conditions. Theoretical and clinical implications of these results are discussed.

PERSPECTIVE

The results of this study revealed that anxiety and the helplessness dimension of pain catastrophizing mediated the relation between attachment and pain severity whereas anxiety and rumination mediated the relation between attachment and depression. Attachment style and cognitive-affective factors might increase vulnerability for problematic pain outcomes in adolescents.

Neuroanatomical correlates of temperament in early adolescents

OBJECTIVE

Temperament refers to enduring behavioral characteristics that underpin individual differences in human behavior, including risk for psychopathology. Research attempting to investigate the neurobiological basis of temperament represents an important step toward elucidating the biological mechanisms underlying these individual differences. In the present study, we examined the relation between four core temperament dimensions and anatomically defined regions of the limbic and prefrontal cortices.

METHOD

We used a cross-sectional design to examine a large sample (N = 153; mean age 12.6 years, SD 0.4, range 11.4-13.7) of healthy early adolescents who were selected from a larger sample to maximize variation in temperament. The main outcome measures were psychometric measures of temperament (four factors: effortful control, negative affectivity, surgency, and affiliativeness) based on the Early Adolescent Temperament Questionnaire-Revised, and volumetric measures of a priori brain regions of interest (anterior cingulate cortex [ACC], orbitofrontal cortex, amygdala, and hippocampus).

RESULTS

We found regional brain volumes to account for small but significant amounts of the variance in self-reported temperament scores. Specifically, higher effortful control was associated with larger volume of the left orbitofrontal cortex and hippocampus. Higher negative affectivity was associated with smaller volume of the left dorsal paralimbic relative to limbic portion of the ACC. Higher affiliativeness was associated with larger volume of the right rostral/ventral limbic portion of the ACC. Affiliativeness and surgency also showed a number of female-specific associations, primarily involving the rostral/ventral ACC.

CONCLUSIONS

Our results provide support for a neuroanatomical basis for individual differences in temperament and have implications for understanding the neurobiological mechanisms underlying the development of a number of psychiatric disorders.
