采用青少年自伤问卷和家庭无效环境问卷对287名特殊家庭青少年和325名普通家庭青少年的自伤行为及与家庭无效环境的关系进行研究。结果发现:特殊家庭青少年的自伤水平显著高于普通家庭青少年;家庭无效环境能显著预测普通青少年和特殊家庭青少年的自伤水平,但对后者的预测力显著高于前者,表明家庭无效环境可能对特殊家庭青少年自伤行为的消极影响更大。 Adolescent self-injury questionnaire and questionnaire on family invalid environment were used to study the relationship between self-injury behaviors of 287 adolescents with special families and adolescents with 325 ordinary families and their relationship with the invalid family environment. The results showed that the level of self-harm of special-family adolescents was significantly higher than that of ordinary family adolescents. The family invalid environment could significantly predict the level of self-infliction of adolescents in ordinary adolescents and special families, but the latter had significantly higher predictive power than the former ones. It may have a more negative impact on self-injury behaviors of adolescents in special families.
