This study tested the relationship between family dynamics and self‐injury. A total of 189 participants responded to a web‐based survey collecting information related to previous self‐injury behaviors and family dynamics. Participants were over 18 years old who had used self‐injury (intentionally harming themselves physically to relieve painful emotions without suicidal intent), but who had not used self‐injury for over a year. Results indicated that healthy family dynamics were negatively correlated and associated with higher scores of self‐injury behaviors. This study offers some evidence that family dynamics influence self‐injury behaviors. The implications for family therapy are discussed.
