To explore the correlation between suicidal attitudes and parental rearing styles in adolescents with depression who have engaged in suicidal behaviors, and to analyze related risk factors. Methods: A cross-sectional survey was conducted on 197 adolescent patients with depression hospitalized in the Department of Clinical Psychology at Jingmen People's Hospital from June 2020 to May 2023, who voluntarily participated in the study. Patients were divided into a suicidal group (115 cases) and a non-suicidal group (82 cases) based on whether they had engaged in suicidal behaviors in the past 6 months. Both groups were assessed using a general information questionnaire, the Patient Health Questionnaire-9 (PHQ-9), the Questionnaire on Suicide Atitude (QSA), and the Egna Minnen av Barndoms Uppfostran (EMBU). Group comparisons were made, and all variables were included in a multivariate Logistic regression model for analysis. Results: (1) The suicidal group was younger in age and had a higher rate of alcohol use than the non-suicidal group (both P<0.05). (2) QSA results showed that the suicidal group had lower scores than the non-suicidal group in attitudes toward suicidal behavior and toward suicide victims (P<0.01 and P<0.05, respectively), but higher scores in attitudes toward the families of suicide victims (P<0.01). There was no significant difference in attitudes toward euthanasia between the two groups (P>0.05). (3) EMBU results revealed that the total score of the suicidal group was significantly higher than that of the non-suicidal group (P<0.01). Specifically, the suicidal group scored lower on maternal emotional warmth (P<0.05) and higher on paternal and maternal overprotection, rejecting denial, and harsh punishment (P<0.01). Additionally, the suicidal group had higher scores on paternal overinterference (P<0.01). (4) Logistic regression analysis identified paternal harsh punishment and excessive interference as risk factors for suicidal behavior in adolescents with depression (P<0.05). Conclusion: Adolescents with depression have a high incidence of suicidal behaviors. Those who engage in suicidal behaviors tend to show understanding or approval of suicide and ambivalence toward the families of individuals who have attempted suicide. Their family education models often lack emotional support and involve excessive interference, punishment, and denial. Adolescents raised by fathers with overinterference, harshness, and punitive parenting styles are at greater risk of suicidal behavior.
