Strategic Insights

— 1 min read

A recent study published in BMC Psychology has found a significant correlation between insomnia and non-suicidal self-injury (NSSI) among university students. The research, conducted by the Training and Research Center, involving 667 students from Jiangsu Province, revealed that 34.03% of the participants had engaged in NSSI. The study also found that insomnia was positively correlated with rumination and NSSI, and that it indirectly influenced NSSI through its effects on subjective well-being and rumination.

Key Takeaways:

  • The prevalence of NSSI among university students was 34.03% (227/667).
  • Insomnia was significantly positively correlated with rumination and NSSI (r = 0.686, 0.400, P).
  • The study concluded that insomnia is a positive predictor of NSSI, and it indirectly influences NSSI through its effects on subjective well-being and rumination.
  • The study used a questionnaire survey to assess insomnia, NSSI, subjective well-being, and rumination among college students.
  • The research supports the idea that addressing insomnia may be a crucial aspect of preventing NSSI among young adults.

Statistics:

  • 34.03% of 667 university students had engaged in non-suicidal self-injury (NSSI).
  • The correlation between insomnia and rumination was significant (r = 0.686).
  • The correlation between insomnia and NSSI was also significant (r = 0.400, P).
  • The study found that insomnia indirectly influenced NSSI through its effects on subjective well-being and rumination.
