Despite the recent advancements in the design and manufacture of prostheses for individuals with craniofacial irregularity and amputation, these individuals tend to become self-conscious about their appearance. The aim of this study was to investigate the reliability and validity of Persian version of the Derriford Appearance Scale24 (P-DAS24) for a sample of individuals with craniofacial irregularity and limb loss.
Reliability of the P-DAS24 was determined by computing internal consistency and test-retest reliability utilizing Cronbach's alpha coefficient and Pearson's correlation coefficient. Discriminant validity was investigated with comparing the total score of the P-DAS24 between disfigured participants and those with no appearance problem. Known-groups validity was evaluated regarding the participants' gender and their level of involvement.
The sample size comprised of 251 individuals with disfigurement and 101 without disfigurement who were deemed normal in appearance. The P-DAS24 showed satisfactory internal consistency (Cronbach's alpha = 0.89) and excellent test-retest reliability (r = 0.96). The total score of the P-DAS24 showed a statistically significant difference between individuals deemed disfigured or normal (P=0.01). The total scores P-DAS24 in individuals with different levels of involvement were significantly different (P<0.001). The scores of the DAS2, DAS18, DAS21, and DAS24 were significantly different between men and women (P<0.01, <0.01, 0.03, and 0.01, respectively).
The P-DAS24 is a valid and reliable tool that may be utilized in clinical practice and researches to assess the outcomes of prosthetic reconstructions in individuals with disfigurement.
尽管近期在为颅面畸形和截肢患者设计和制造假体方面取得了进展，但这些患者往往会对自己的外表感到难为情。本研究的目的是调查波斯语版德里福德外貌量表24（P-DAS24）在颅面畸形和肢体缺失患者样本中的信度和效度。
通过使用克朗巴赫α系数和皮尔逊相关系数计算内部一致性和重测信度来确定P-DAS24的信度。通过比较毁容参与者和无外貌问题参与者之间的P-DAS24总分来研究区分效度。根据参与者的性别及其参与程度评估已知群体效度。
样本包括251名有毁容的个体和101名无毁容且外表被认为正常的个体。P-DAS24显示出令人满意的内部一致性（克朗巴赫α系数=0.89）和出色的重测信度（r=0.96）。P-DAS24的总分在被认为毁容或正常的个体之间显示出统计学上的显著差异（P=0.01）。不同参与程度个体的P-DAS24总分存在显著差异（P<0.001）。DAS2、DAS18、DAS21和DAS24的得分在男性和女性之间存在显著差异（分别为P<0.01、<0.01、0.03和0.01）。
P-DAS24是一种有效且可靠的工具，可用于临床实践和研究，以评估毁容患者假体重建的效果。
