The purpose of this study was to estimate the prevalence of depression in patients with social anxiety disorder (SAD) and to assess the relationship between the severity of SAD symptoms and depression. Ninety-eight consecutive patients with generalized SAD according to DSM-IV criteria were included in a cross-sectional case-control study. Patients were referred to a psychiatric outpatient clinic in a general hospital in Saudi Arabia. The Liebowitz Social Anxiety Scale was used to estimate the severity of SAD. Fifty-eight (59%) of the patients with SAD had another current psychiatric disorder. Forty (41%) patients had current depression, and 37 (92.5%) of them had it after SAD onset. Eleven of 16 patients with severe SAD (69%) had depression whereas only 29 of 82 of SAD patients with mild or moderate subtypes (35%) had depression. Patients with severe SAD were four times more likely to have depression than the patients with mild or moderate SAD even after controlling for confounding sociodemographic and clinical factors. Depression is common among patients with SAD, particularly the severe subtype. Early recognition and treatment of SAD, especially the severe subtype, may prevent the occurrence of depression. Prospective studies are needed to investigate the risk factors that may lead to depression in SAD.
本研究的目的是估计社交焦虑障碍（SAD）患者中抑郁症的患病率，并评估SAD症状严重程度与抑郁症之间的关系。根据《精神疾病诊断与统计手册》第四版（DSM-IV）标准，98例连续性广泛性SAD患者被纳入一项横断面病例对照研究。这些患者均被转诊至沙特阿拉伯一家综合医院的精神科门诊。使用利博维茨社交焦虑量表来评估SAD的严重程度。58例（59%）SAD患者目前还患有其他精神疾病。40例（41%）患者目前患有抑郁症，其中37例（92.5%）是在SAD发病后患上抑郁症的。16例重度SAD患者中有11例（69%）患有抑郁症，而82例轻度或中度亚型SAD患者中只有29例（35%）患有抑郁症。即使在控制了社会人口统计学和临床混杂因素之后，重度SAD患者患抑郁症的可能性仍是轻度或中度SAD患者的四倍。抑郁症在SAD患者中很常见，尤其是重度亚型。早期识别和治疗SAD，特别是重度亚型，可能会预防抑郁症的发生。需要进行前瞻性研究来调查可能导致SAD患者患抑郁症的危险因素。
