PURPOSE
Eating disorders (ED) and social anxiety disorder are highly comorbid with potentially shared symptoms like social appearance anxiety (SAA) referring to a fear of being negatively evaluated by others' because of overall appearance. SAA constitutes a risk factor for eating psychopathology and bridges between EDs and social anxiety disorder.
METHODS
The present studies examined internal consistency, factor structure, test-retest reliability, gender and age invariance, convergent validity and differences between individuals with and without an ED of a German version of the social appearance anxiety scale (SAAS) in four independent samples (n = 473; n = 712; n = 79; n = 33) including adolescents and patients with EDs.
RESULTS
Consistently, the SAAS showed excellent internal consistency (ωs ≥ 0.947) and a one-factorial structure. Convergent validity was shown via high correlations of the SAAS with social anxiety (e.g., social interaction anxiety r = 0.642; fear of negative evaluation rs ≥ 0.694), body image disturbance measures (e.g., shape concerns rs ≥ 0.654; weight concerns rs ≥ 0.607; body avoidance rs ≥ 0.612; body checking rs ≥ 0.651) and self-esteem (r = -0.557) as well as moderate correlations with general eating psychopathology (e.g., restrained rs ≥ 0.372; emotional r = 0.439; external eating r = 0.149). Additionally, the SAAS showed gender and age invariance and test-retest reliability after 4 weeks with r = 0.905 in Study 2 and was able to discriminate between individuals with and without an ED in Study 4.
CONCLUSION
Hence, the German version of the SAAS can reliably and validly assess SAA in female and male adolescents or adults with or without an ED. Additionally, the SAAS might be used in a therapeutic context to especially target patient groups suffering from EDs with comorbid social anxiety.
LEVEL OF EVIDENCE
Level III: Evidence obtained from cohort or case-control analytic studies.
目的
饮食失调（ED）和社交焦虑症高度共病，可能存在社交外表焦虑（SAA）等共同症状，指的是因为整体外表而担心被他人负面评价的恐惧。SAA 是饮食病理学的一个风险因素，在 EDs 和社交焦虑症之间架起了桥梁。
方法
本研究在四个独立样本（n=473；n=712；n=79；n=33）中，使用德国社交外表焦虑量表（SAAS）的版本，检查了内部一致性、因素结构、重测信度、性别和年龄不变性、聚合效度以及有无 ED 个体之间的差异，这些样本包括青少年和 ED 患者。
结果
SAAS 始终表现出极好的内部一致性（ωs≥0.947）和单因素结构。通过与社交焦虑的高相关性（例如，社交互动焦虑 r=0.642；负面评价恐惧 rs≥0.694）、身体意象障碍测量（例如，形状关注 rs≥0.654；体重关注 rs≥0.607；身体回避 rs≥0.612；身体检查 rs≥0.651）和自尊（r=-0.557）以及与一般饮食病理学的中度相关性（例如，克制 rs≥0.372；情感 r=0.439；外部进食 r=0.149），显示出聚合效度。此外，SAAS 还表现出性别和年龄不变性，并且在第 2 项研究中经过 4 周的重测，重测信度为 r=0.905，并且能够在第 4 项研究中区分有无 ED 的个体。
结论
因此，SAAS 的德语版本可以可靠且有效地评估女性和男性青少年或成年患者中有无 ED 的 SAA。此外，SAAS 可在治疗环境中用于针对患有 ED 且伴发社交焦虑症的患者群体。
