Life Satisfaction Linked to Non-Suicidal Self-Injury in Adolescents

Strategic Insights -

A recent study published in Acta Psychologica explores the relationship between life satisfaction and non-suicidal self-injury (NSSI) among adolescents. Researchers from Shandong Provincial Hospital Affiliated to Shandong First Medical University in China investigated how life satisfaction influences NSSI and identified its underlying mechanisms among adolescent patients. The study found that life satisfaction can negatively predict the occurrence of NSSI behavior.

Key Takeaways:

  • The study, published in Acta Psychologica, aimed to investigate how life satisfaction influences non-suicidal self-injury (NSSI) among adolescents and identify its underlying mechanisms.
  • A total of 1039 participants were included in the study, which was conducted from January to December 2023.
  • The survey included a general demographic information questionnaire, an adolescent self-harm questionnaire, the Patient Health Questionnaire-9, Perceived Deficits Questionnaire-Depression 5-item, and the Adolescent Student Life Satisfaction Scale.
  • Mediation analysis was performed to examine the potential causal chain between depression and cognitive impairment mediating the relationship between life satisfaction and NSSI.
  • The results revealed that life satisfaction can negatively predict the occurrence of NSSI behavior (β = 0.278, P < 0.001).
  • The study concluded that life satisfaction can influence NSSI through the mediation of depressive symptoms and cognitive dysfunction.
  • The study provides a theoretical reference for the alleviation of NSSI among adolescents.
