Neuroanatomical Correlates of Perceived Stress Controllability in Adolescents and Emerging Adults

Self-esteem buffers the stress sensitizing effect of childhood maltreatment on adolescent nonsuicidal self-injury

BACKGROUND

Adversity in childhood increases the risk of psychopathology, perhaps by influencing sensitivity to recent stressful life events (SLEs). However, little is known about the stress-sensitizing effect of childhood adversity on nonsuicidal self-injury (NSSI), whether stress sensitization exists in specific types of SLEs, and the stress-buffering effect of self-esteem. This study aimed to investigate whether exposure to child maltreatment increases adolescent's vulnerability to the effects of dependent and independent SLEs on later NSSI and whether self-esteem buffers this risk.

METHODS

We conducted a two-wave study with 18-month intervals. 601 Chinese adolescents completed self-report measures of child maltreatment, SLEs, self-esteem, and NSSI.

RESULTS

Results supported the stress sensitization hypothesis for child maltreatment regarding dependent SLEs, with dependent SLEs significantly predicting later NSSI only in maltreated adolescents. Moreover, self-esteem buffered the relationship between dependent SLEs and NSSI in maltreated adolescents but amplified the relationship in non-maltreated adolescents. In the maltreated group, dependent SLEs predicted increased NSSI only in those with low self-esteem. In contrast, in the control group, dependent SLEs were significantly associated with NSSI in individuals with high self-esteem.

LIMITATIONS

We did not collect information on the timing of exposure to child maltreatment. Future studies that assess child maltreatment during critical periods of development may be able to identify sensitive period in which maltreatment sensitizes individuals to stress in adolescents.

CONCLUSION

Findings provide preliminary evidence that child maltreatment has a stress-sensitizing effect on adolescent NSSI. Improving self-esteem may mitigate the associations between SLEs and NSSI in adolescents exposed to child maltreatment.

The Role of Self-Compassion and Attributions in the Mental Health of Older Adolescents amid the COVID-19 Pandemic

This study aimed to examine the relationship among self-compassion, attributional styles, and mental health and their components in older adolescents in the context of the COVID-19 pandemic. The role of each component of self-compassion (self-kindness, common humanity, mindfulness, self-judgment, isolation, and over-identification) and attributions (globality, stability, self-worth, and negative consequences) in predicting mental health was also analyzed. There were 322 participants aged 18 to 22 that participated in an online survey. The participants filled out a form that consisted of sociodemographic questions, COVID-19-related questions, the Self-Compassion Scale, the Mental Health Continuum-short form-and the Cognitive Styles Questionnaire-very short form. The results indicated moderate levels of self-compassion, attributions, and mental health in participants. Furthermore, gender differences in self-compassion were confirmed, meaning that male participants had higher total levels of self-compassion, and certain differences were observed on attribution subscales, but not on well-being subscales. Self-compassion and mental health were found to be positively correlated with each other and negatively correlated with negative attributions. Of the four attributional components, stability and negative consequences were revealed to be significant negative predictors in the first step but lost their significance with the inclusion of self-compassion components in the second step of the analysis. Regarding the six components of self-compassion, self-kindness, recoded isolation, and common humanity were significant positive predictors in the second step of the analysis. COVID-19-related items did not show any significant intergroup differences. Our findings contribute to a better understanding of the relationship between positive mental health, self-compassion, and attributions in older adolescents so that they can be used as theoretical support for related interventions, especially during and after times of crisis, such as a pandemic.

Depression and anxiety of medical students at Kunming Medical University during COVID-19: A cross-sectional survey

An isolation strategy was used to control the transmission and rapid spread of COVID-19 in Yunnan. As a result, students were supposed to stay at home and disrupted their outside activities. It led to a detrimental influence on students' mental health. The purpose of this study was to investigate the prevalence and risk factors of depression and anxiety among medical students and to provide ideas for the prevention of depression and anxiety in medical students. A cross-sectional survey was conducted among 2,116 medical students at Kunming Medical University from July 8 to July 16, 2020. Participants' demographic and living conditions were collected. Depression and anxiety were measured using the Patient Health Questionnaire 9 and General Anxiety Disorder-7, respectively. Uni- and multivariate logistic regression analyses were performed to detect risk factors associated with depression and anxiety. The prevalence rates of depression and anxiety among medical students were 52.5 and 29.6%, respectively. Depression was more likely to be caused by low grades, lack of physical exercise, drug use, irregular diet, extensive screen time on mobile phones, being greatly affected by the COVID-19 pandemic, and inadaptability to offline courses. Anxiety was more likely to be caused by lack of physical exercise, drug use, irregular diet, and inadaptability to offline courses. Depression and anxiety are highly comorbid. Our study showed predictive factors for depression and anxiety and identified a major mental health burden on medical students during the COVID-19 outbreak. More targeted measures should be taken to improve the mental state of students to reduce the incidence of depression and anxiety.
