Yet, whether self\u2010help interventions have broader mental health benefits beyond symptom and risk reduction remains unclear. As randomized controlled trials (RCTs) also assess general mental health secondary to eating disorder symptoms, we conducted a meta\u2010analysis to investigate whether and to what extent pure self\u2010help interventions for eating disorders produce improvements in these secondary outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Twenty\u2010seven RCTs of pure self\u2010help interventions for the prevention or treatment of eating disorders were included. Mean age ranged from 16 to 46\u2009years. Most self\u2010help interventions were based on cognitive\u2010behavioral therapy. Most interventions were delivered via digital means (Internet, apps, etc.). Random effects meta\u2010analyses were conducted on six outcomes: depression, anxiety, general distress, quality of life, self\u2010esteem, and psychosocial impairment.
