Committing a family member with schizophrenia to a psychiatric ward is a coping mechanism often employed under challenging circumstances. This decision entails significant emotional repercussions and ethical dilemmas, potentially undermining the psychological well-being of the family and eroding public trust in mental health services and professionals. This study investigates the experiences of regret among family members after deciding to commit a relative to a locked ward, adhering to the COREQ guidelines. Employing a descriptive qualitative methodology, we conducted in-depth interviews with 14 family members in Heilongjiang Province, China, who faced this difficult choice. Data were analysed using reflexive thematic analysis, which identified seven themes within three stages: Decision antecedent (limited comprehension of schizophrenia and treatment, deficiencies in supportive environment), decision process (suboptimal communication, hospitalisation and weighing of alternative options) and decision outcome (emotional burden of a loved one's hospital life, the indelible mark of schizophrenia, impact on family dynamics). The study highlights the need for targeted interventions, including addressing biased social media portrayals, enhancing the accuracy of medical information, ensuring transparency in psychiatric practices and improving support for families during hospitalisation.
