This study examines symptoms of denial in 86 adolescents with anorexia nervosa (AN) using a dataset from a family therapy trial.
Using the Restraint subscale of the Eating Disorders Examination (EDE) at baseline, participants were divided into deniers (n = 15), minimizers (n = 21), and admitters (n = 50). These subgroups were compared with analysis of variance (ANOVA; Tukey post-hoc analysis) on a variety of assessment and treatment variables at baseline and at 12 months.
Although body mass index (BMI) was not significantly different, all subscale scores of the EDE were lower in the deniers compared with the admitters (p = .0001 for all subscales) at baseline. Minimizers also scored lower than admitters on 3 of 4 subscales (p = .0001 for the Restraint, Weight Concern, and Shape Concern subscales of the EDE). At baseline and at 12 months, there were no significant differences on the Youth Self-Report or the Child Behavior Checklist. At 12 months, the only significant difference was in the Restraint subscale, with deniers still scoring lower than admitters (p = .015).
Denial and minimization appear to be common processes occurring in adolescents with AN and present difficulties in assessment.
本研究使用一项家庭治疗试验的数据，对86名神经性厌食症（AN）青少年的否认症状进行研究。
在基线时使用饮食失调检查（EDE）的克制分量表，将参与者分为否认者（n = 15）、轻视者（n = 21）和承认者（n = 50）。在基线和12个月时，对这些亚组在各种评估和治疗变量上进行方差分析（ANOVA；Tukey事后分析）比较。
尽管体重指数（BMI）无显著差异，但在基线时，与承认者相比，否认者的EDE所有分量表得分均较低（所有分量表p = .0001）。轻视者在4个分量表中的3个上得分也低于承认者（EDE的克制、体重关注和体型关注分量表p = .0001）。在基线和12个月时，青少年自我报告或儿童行为检查表无显著差异。在12个月时，唯一显著差异在于克制分量表，否认者得分仍低于承认者（p = .015）。
否认和轻视似乎是神经性厌食症青少年中常见的过程，且在评估中存在困难。
