Objective To explore parents′ psychological experience of non-suicidal self injury(NSSI) behaviors in adolescents with depression, and to provide a reference for developing targeted family intervention measures.Methods The parents of 15 hospitalized adolescents with depression who had experienced NSSI behaviors were interviewed, and the themes were analyzed, summarized and refined by the Colaizzi′s 7-step analysis.Results The parents′ psychological experience of NSSI behaviors in adolescents with depression were summarized into five themes:before self-injury, some of them focused on their work and ignored their children′s emotional needs; at the initial stage of exposure, they were unable to control themselves to speak excessively, and complained, felt self-blame and emotional fragile; at the early stage of treatment, they were anxious and wandering, afraid of being exposed and unwilling to seek medical treatment; at the stage of treatment, they had no choice but to lower their own expectations and tried hard to make changes to cater for their children;and at the stage of recovery, their thoughts were contradictory, they had difficulty in making a decision, and worried about the children′s future growth at the same time.Conclusion Parents of adolescents with depression have complicated psychological experience of their children′s NSSI behaviors, and family factors have an important influence on adolescents′ behavior, so parents should be guided to provide correct family support to their children.
