To estimate the prevalence of autism spectrum disorders (ASD) among adult psychiatric out-patients; to evaluate the efficacy of a new brief screening questionnaire (ASDASQ).
1323 adult psychiatric out-patients were screened by staff. Analysis of psychiatric records of patients (n = 66) scoring high on the ASDASQ yielded 31 patients with a suspected ASD. Twenty-two of these patients were clinically examined. Three psychometric aspects of the questionnaire were studied.
Seventeen patients were found by clinical examination to have an ASD. Since two patients scoring low on the ASDASQ were known to have an ASD, at least 19 patients in this population (1.4%) had a definite ASD. Seventeen of the ASD patients had been previously diagnosed with other psychiatric disorders, most frequently schizophrenia (n = 5). Of patients attending a treatment centre for severe psychiatric disabilities (n = 499), 3.2% had an ASD. The ASDASQ showed good reliability across and within raters. Internal consistency was excellent.
Adult psychiatric patients sometimes have undiagnosed autism spectrum disorders. The ASDASQ can be useful for screening.
评估成年精神科门诊患者中自闭症谱系障碍（ASD）的患病率；评估一种新的简短筛查问卷（ASDASQ）的有效性。
工作人员对1323名成年精神科门诊患者进行筛查。对在ASDASQ上得分较高的66名患者的精神科记录进行分析，发现31名患者疑似患有ASD。其中22名患者接受了临床检查。对该问卷的三个心理测量方面进行了研究。
临床检查发现17名患者患有ASD。由于已知两名在ASDASQ上得分较低的患者患有ASD，因此该人群中至少有19名患者（1.4%）患有确诊的ASD。17名ASD患者之前被诊断患有其他精神疾病，最常见的是精神分裂症（5例）。在重度精神残疾治疗中心就诊的499名患者中，3.2%患有ASD。ASDASQ在评分者之间和评分者内部均显示出良好的信度。内部一致性极佳。
成年精神科患者有时存在未被诊断的自闭症谱系障碍。ASDASQ可用于筛查。
