Few studies have recruited adults with a formal diagnosis of muscle dysmorphia (MD), a psychological illness defined by preoccupation that one lacks muscularity and/or leanness, combined with significant functional impairment. This study presented descriptive statistics for a range of clinically relevant questionnaires in one of the largest samples of adults with confirmed diagnoses of MD.
We recruited 29 adults who met diagnostic criteria for MD as determined by semi-structured diagnostic interviews and administered a battery of questionnaires assessing MD symptomology, compulsive exercise, and disordered eating. Descriptive statistics were calculated for both total and subscale scores for each questionnaire. Raincloud plots are included to show the distribution of total scores.
Of the 29 participants, 26 completed all questionnaires. Mean scores were high across all questionnaires and broadly consistent with results in past studies that also recruited a clinical MD sample. Most participants scored above proposed clinical cut-off scores for questionnaires assessing compulsive exercise and disordered eating.
This study adds to the small body of published questionnaire data in clinical MD samples. We stress that questionnaire scores should not be used alone to infer the presence of MD, but could be considered as a useful adjunct to a comprehensive clinical interview.
很少有研究招募过患有肌肉变形障碍（MD）的成年人，MD 是一种由对自己的肌肉发达程度和/或消瘦程度的过分关注，以及显著的功能障碍所定义的心理疾病。本研究提供了一系列临床上相关问卷的描述性统计数据，这些问卷是在最大的一组确诊 MD 成年人样本中进行的。
我们招募了 29 名符合 MD 诊断标准的成年人，这些标准是通过半结构化的诊断访谈确定的，并对他们进行了一系列问卷评估，包括 MD 症状、强迫性运动和饮食失调。每个问卷的总分和子量表得分都计算了描述性统计数据。Raincloud 图显示了总分的分布。
在 29 名参与者中，有 26 名完成了所有问卷。所有问卷的平均得分都很高，与同样招募临床 MD 样本的过去研究的结果大致一致。大多数参与者在评估强迫性运动和饮食失调的问卷上的得分高于建议的临床临界值。
本研究增加了临床 MD 样本中已发表问卷数据的数量。我们强调，问卷得分不应单独用于推断 MD 的存在，而可以作为全面临床访谈的有用补充。
