Abstract |
AIMS: The objectives of the present study were to (i) evaluate the prevalence of children and adolescents who have engaged in intentional self-harm using a sharp object; and (ii) investigate the relationship between self-harm with sharp objects and depressive tendencies or dissociative tendencies. METHODS: A total of 1938 students in grades 5-12 in Yokohama, Japan, were enrolled, and they completed anonymous self-report questionnaires including a question about intentional self-harm with a sharp object, the Depression Self-Rating Scale for Children (DSRSC) and the Adolescent Dissociative Experiences Scale (A-DES). RESULTS: The prevalence of self-harm using sharp object was 5.4% among male 5th-6th graders, 4.0% among female 5th-6th graders, 5.3% among male 7th-9th graders, 15.1% among female 7th-9th graders, 6.6% among male 10th-12th graders, and 9.6% among female 10th-12th graders. Categorical regression analysis showed that a small amount of variance in self-harm by sharp object was explained by DSRSC and A-DES scores. CONCLUSIONS: Self-harm with a sharp object was prevalent among pre-adolescents and adolescents and was associated with depressive and dissociative tendencies. Language: en |
