Open access. Comment. Another randomised trial, the Self-Harm Intervention: Family Therapy (SHIFT) trial,1 has shown no benefit for another psychological therapy versus treatment as usual in adolescents who have self-harmed. Furthermore, in the study by David Cottrell and colleagues1 in The Lancet Psychiatry, rates of self-harm repetition were high across the family therapy and treatment as usual groups. These disappointing results have notable implications for future research in the field of adolescent self-harm..
