This study assessed demographic and clinical features in 65 subjects with body dysmorphic disorder (BDD) and compared the 39 (60%) with the delusional form (receiving an additional diagnosis of delusional disorder, somatic type) with those who did not meet delusionality criteria. Delusional and nondelusional patients did not statistically differ on most demographic and clinical variables. Delusional patients, however, had significantly more severe BDD symptoms at both baseline and follow-up assessments than those of nondelusional patients. Furthermore, poorer insight was significantly associated with more severe BDD symptoms at both baseline and follow-up. Overall improvement in BDD symptom severity was similar for the 2 groups. Our results support other studies in the view that BDD and its delusional variant have more similarities than differences and that the delusional variant may be simply a more severe form of BDD. Implications for the diagnostic classification of BDD and future research directions are discussed.
本研究评估了 65 名躯体变形障碍（BDD）患者的人口统计学和临床特征，并将其中 39 名（60%）有妄想形式的患者（另外诊断为妄想障碍，躯体类型）与不符合妄想标准的患者进行了比较。妄想和非妄想患者在大多数人口统计学和临床变量上没有统计学差异。然而，妄想患者在基线和随访评估时的 BDD 症状严重程度明显比非妄想患者更严重。此外，洞察力较差与基线和随访时 BDD 症状严重程度的相关性显著。两组患者的 BDD 症状严重程度总体改善情况相似。我们的研究结果支持其他研究的观点，即 BDD 及其妄想变体有更多的相似之处，而不是差异，并且妄想变体可能只是 BDD 的一种更严重形式。讨论了对 BDD 的诊断分类和未来研究方向的影响。
