Objective To deeply understand the stigma experience of adolescents with suicide attempts, so as to provide reference for psychosomatic rehabilitation of these adolescents. Methods Using hermeneutic phenomenological approach, we selecte 15 adolescent patients who had attempted suicide during March and December 2022 for semi-structured interviews.Colaizzi′s seven-step analysis method was used to extract themes. Results A total of 3 themes and 9 sub-themes were extracted, namely, negative emotional experience of self-stigma (shame and self-blame, despair and anger), negative experience of public stigma (family members′ misunderstandings deepened shame and anger, feeling a gap between the feedback of teachers and classmates and adolescents′ own expectations, feeling dejected by netizens′ verbal abuses), negative coping after negative experience (poor intention of self-disclosure, re-suicidal thoughts, avoidance of professional help, avoidance of normal interpersonal interactions). Conclusion Adolescents with suicide attempts have strong negative emotions of self-stigma and public stigma, which lead to negative coping. Therefore, we should actively adjust the one-sided perception of stigma among adolescents with suicide attempts, improve their ways of coping with stigma, promote physical and mental rehabilitation of adolescents with suicide attempts, and prevent the occurrence of re-suicide.
