Methods: The psychological status and parenting styles of 82 adolescents with self-injurious behavior were studied in a controlled manner using the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Beck Scale for suicide ideation-Chinese Version (BSI-CV), and Egna Minnen av Barndoms Uppfostran (EMBU). Results: The observation group had a higher proportion of large families, left-behind children, and divorced families than the control group (P t = −8.433, −7.682, −13.622, P t = −8.433, −7.682, −13.622, P t = −9.143, −8.441, −6.672, −2.901, P P P < 0.01). Conclusion: Non-suicidal self-injury (NSSI) is more common among adolescents in families with females, multiple children, divorced parents, and left-behind children. These families often exhibit numerous negative parenting practices. Excessive protection by fathers and overprotection and excessive interference by mothers are risk factors for the emergence of suicidal tendencies among adolescents who engage in NSSI.展开更多
