Cognitive-emotional networks in students with and without a history of non-suicidal self-injury

The impact of negative cognitive bias on NSSI: mediating non-adaptive cognitive emotion regulation strategies

BACKGROUND

Individuals may be more likely to engage in NSSI due to negative cognitive bias, while the use of negative emotional regulation mechanisms may further contribute to NSSI. Currently, there is a dearth of studies regarding the correlation among the three variables.

METHOD

The study employed convenience sampling to collect data via online platforms from a total of 572 college students in Harbin, Heilongjiang Province, China, over the period of January 2024 to February 2024. The questionnaires comprise the Non-Adaptive Cognitive Emotion Srategy Regulation Subscale, the Negative Cognitive Processing Bias Questionnaire, and the NSSI Questionnaire.

OUTCOME

Negative cognitive bias significantly and directly influences NSSI, as indicated by a beta coefficient of 0.3788 and a confidence interval of [0.2878, 0.4698]. The existence of negative cognitive bias significantly enhances the impact of non-adaptive cognitive emotion control approaches (β = 0.5613, CI [0.4808, 0.6418]). Non-adaptive cognitive emotion regulation strategies showed a significant effect on NSSI, as indicated by a beta coefficient of 0.2033 and a confidence interval of [0.0942, 0.3125]. The non-adaptive cognitive emotion control strategy serves as an intermediary between negative cognitive bias and NSSI, explaining 30.12% of the overall impact.

IN CONCLUSION

The results demonstrate that non-adaptive cognitive emotion regulation strategies play a partially moderating role in the relationship between negative cognitive bias and NSSI among nursing students. We emphasize the importance of non-adaptive cognitive emotion regulation strategies, negative cognitive biases, and NSSI among nursing students. In order to reduce the occurrence of NSSI, it is important for schools, families, and teachers to work together closely and implement a well-organized and efficient intervention to protect the mental well-being of nursing students.

The relationship between mobile phone addiction and non-suicidal self-injury: Findings from six universities in Shaanxi province, China

BACKGROUND

Although the development and application of mobile phones have changed various aspects of people's lives, excessive use of mobile phones has also raised physical and mental health concerns. However, the relationship between mobile phone addiction (MPA) and non-suicidal self-injury (NSSI) is unclear.

METHODS

A cross-sectional study was conducted (2022) among students from six universities to assess the relationship between MPA and NSSI. A Mobile Phone Addiction Tendency Scale (MPATS) was used to assess MPA, while NSSI was assessed via The Ottawa Self-Injury Inventory. Binary logistic regression models were used to assess the relationship between MPA and NSSI.

RESULTS

A total of 18,723 college students (6531 males [34.9 %] and 12,192 females [65.1 %]) were included in the final analyses. The prevalence of NSSI during the past 12 months was 6.5 %. Furthermore, 5553 participants (29.7 %) met the MPA criteria (MPATS score ≥ 48), and the average MPATS score was 39.5 ± 13.0. MPA was associated with increased odds of NSSI after adjusting for socio-demographic characteristics, health-related characteristics, and relevant psychosocial variables (OR, 1.29; 95 % CI, 1.13-1.46). Moreover, gender did not affect the association of MPA and MPATS score with NSSI (P for interaction>0.05). The restricted cubic splines regression showed that a monotonically increasing risk of NSSI was associated with increasing MPATS score (P for non-linearity = 0.474).

CONCLUSIONS

MPA is associated with increased odds of NSSI among college students, indicating that early examination, prevention, and intervention for MPA may prevent and control NSSI.

Risk factors, theoretical models, and biological mechanisms of nonsuicidal self-injury: a brief review

Nonsuicidal self-injury (NSSI) refers to the direct, deliberate infliction of harm to one's body tissue without the intention to die. The prevalence of NSSI has increased significantly globally in recent years and has become an important public health problem affecting the health of people, especially adolescents. The occurrence of NSSI in adolescents is the result of the interaction of different factors. Many scholars have proposed various theoretical models to explain the mechanism of NSSI behavior based on previous research on the influencing factors of NSSI. Moreover, advances have been made in genetic and neuroimaging mechanisms related to NSSI. Understanding the genetic and neuroimaging mechanisms of NSSI is important for both describing and treating the disorder. This literature review discusses the progress made on the risk factors, theoretical models, and biological mechanisms of NSSI.
