This study investigates the outcome of anorexia nervosa in adolescents in relation to precipitating life events and changes in family functioning over time.
Thirty-five adolescents with anorexia nervosa and their mothers were administered measures of life events and family functioning at initial assessment and 1 and 2 year follow-up, when outcome was also assessed.
Fifty-five per cent of patients had a good outcome. Patients from initially well-functioning families or those with precipitating life events improved more in the first year, than those with dysfunctional families or without events. Subjects perceived a deterioration in family functioning at 1 year follow-up but an improvement at 2 years. Mothers reported no changes.
Approximately half of a series of early onset cases of anorexia nervosa can be expected to recover by 2 years. Healthy family functioning and presence of a precipitating life event predict good short-term outcome. The relationships between subjects' perceptions of family functioning and their recovery from anorexia nervosa is discussed.
本研究调查青少年神经性厌食症的预后与引发生活事件及家庭功能随时间变化之间的关系。
35名患有神经性厌食症的青少年及其母亲在初始评估、1年及2年随访时接受了生活事件和家庭功能测量，同时对预后进行评估。
55%的患者预后良好。来自初始家庭功能良好或有引发生活事件的患者在第一年的改善比家庭功能失调或无此类事件的患者更大。受试者在1年随访时感觉家庭功能恶化，但在2年时有所改善。母亲们报告无变化。
一系列早发性神经性厌食症病例中约一半有望在2年内康复。健康的家庭功能和存在引发生活事件预示着良好的短期预后。讨论了受试者对家庭功能的认知与他们从神经性厌食症中康复之间的关系。
