The Impact of Parent-Child Alienation on Adolescents'Non-Suicidal Self-Injury:A Moderated Mediating Model
Objective:To explore the impact of father-child/mother-child alienation on adolescents'non-suicidal self-injurious behavior,the mediating role of anxiety and the moderating role of expression suppression.Methods:The sample consisted of 2465 middle school students from junior middle school Grade 1 to high school Grade 3 who completed mea-sures of The Inventory of Parent and Peer Attachment,Self-Rating Anxiety Scale,Adolescents Self-harm Scale and Emo-tion Regulation Questionnaire.Results:(1)Both father-child alienation and mother-child alienation significantly predicted adolescents'non-suicidal self-injurious behavior;(2)Anxiety played a part mediating role between father-child alienation and mother-child alienation and adolescents'non-suicidal self-injurious behavior;(3)Expression suppression played a moderating role between anxiety and non-suicidal self-injury.The more frequently the expression suppression strategies used,the stronger the predictive effect of anxiety on non-suicidal self-injurious behavior.Conclusion:The quality of par-ent-child attachment relationship can directly affect non-suicidal self-injurious behavior in adolescents,and may indirect-ly affect non-suicidal self-injurious behavior by influencing adolescents'anxiety.
