Objective: To determine the association between adolescent hospitalization for suicide attempts and the subsequent risk of eating disorder hospitalization. Method: This was a cohort study of 162,398 adolescent girls in Quebec, Canada, including 7741 with suicide attempts before 20 years of age, matched to 154,657 adolescents with no attempt between 1989 and 2019. The main exposure measure was suicide attempt hospitalization. The main outcome measure was hospitalization for an eating disorder up to 31 years later, including anorexia nervosa, bulimia nervosa, and other eating disorders. We used adjusted Cox regression models to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association between adolescent suicide attempts and eating disorder hospitalization. Results: Adolescent girls admitted for a suicide attempt had 5.55 times the risk of eating disorder hospitalization over time (95% CI 3.74–8.23), compared with matched controls. Suicide attempt was associated with anorexia nervosa (HR 3.57, 95% CI 1.78–7.17) and bulimia nervosa and other eating disorders (HR 8.55, 95% CI 5.48–13.32). Associations were pronounced in girls with repeated suicide attempts. Girls who attempted suicide through self‐poisoning had an elevated risk of anorexia nervosa, whereas girls who used violent methods such as cutting or piercing had a greater risk of bulimia nervosa and other eating disorders. Suicide attempt was strongly associated with eating disorder hospitalization in the year following the attempt, but associations persisted throughout follow‐up. Discussion: Suicide attempt admission is associated with the long‐term risk of eating disorder hospitalization in adolescent girls. Public Significance: This study of adolescent girls suggests that suicide attempt admission is associated with the long‐term risk of hospitalization for eating disorders. The risk is greatest in the year after the attempt, but persists over time. Adolescents who present with a suicide attempt may benefit from screening for eating disorders and long‐term follow‐up to help prevent the exacerbation or development of eating disorders.

According to Self‐Determination Theory, when motivation to reach an objective is fully internal, it is said to be "autonomous"; when driven by external incentives, it is said to be "controlled". Previous research has indicated that autonomously motivated individuals show better response to treatments for eating disorders. Objective: In individuals undergoing different intensities of outpatient treatment for an eating disorder, we sought to assess associations between autonomous and controlled motivations and response to treatment on the one hand, and likelihood of dropping out of treatment, on the other. Method: Seven hundred seventy adults meeting DSM‐5 criteria for an eating disorder (216 with Anorexia Nervosa, 282 with Bulimia Nervosa, and 272 with Other Specified Feeding or Eating Disorder) were included in this study. Before an interval of outpatient treatment, individuals completed the Eating Disorder Examination Questionnaire and the Autonomous and Controlled Motivations for Treatment Questionnaire. Participants completed the Eating Disorder Examination Questionnaire again at one or two subsequent timepoints. Results: After controlling for diagnosis, treatment intensity, and number of previous treatments, analyses showed that higher autonomous motivation was associated with better response on eating‐disorder overall symptoms and lower likelihood of dropping out of treatment. In contrast, controlled motivation was not associated with response to treatment. Discussion Our results suggest that autonomous motivation has trans‐diagnostic influence upon response to various intensities of treatment for an eating disorder. In support of an autonomy supportive approach to treatment, findings link autonomous motivation with more favorable outcome. [ABSTRACT FROM AUTHOR]
