Computer-administered versions of two clinician-administered symptom rating scales for social anxiety (the Liebowitz Social Anxiety Scale [LSAS] and the Brief Social Phobia Scale [BSPS]) and one paper-and-pencil scale (the Fear Questionnaire) were developed and utilized in a clinical trial for social phobia. The reliability and validity of the computer versions were examined, as were their equivalence to the traditional versions. Correlations between the computer and original versions were high at baseline, and remained high throughout the study. The internal consistency reliability of the computer scales was also high, and almost identical to the original versions. Mean score differences between computer and original versions were not significant at baseline, and no significant differences were found between computer and traditional versions on the amount of change detected from baseline to endpoint. Seventy-seven percent of subjects felt that the computer did not interfere with their visit at baseline and a plurality (36%) preferred the computer, with 30% preferring the clinician and 34% having no preference. By the end of the study, the plurality (41%) had no preference, with 27% preferring the computer and 32% preferring the clinician. Results support the use of these computer-administered symptom rating scales of social anxiety as a viable alternative to the clinician-administered versions with this subset of patients, which should offer researchers and clinicians a reliable and cost-effective method for evaluating social phobia.
针对社交焦虑症，开发了两种临床医生使用的症状评定量表（利博维茨社交焦虑量表[LSAS]和简短社交恐惧症量表[BSPS]）的计算机管理版本，以及一种纸笔量表（恐惧问卷），并在一项社交恐惧症临床试验中加以运用。对计算机版本的信度和效度进行了检验，同时也检验了它们与传统版本的等效性。计算机版本与原始版本在基线时的相关性很高，并且在整个研究过程中一直保持很高。计算机量表的内部一致性信度也很高，几乎与原始版本相同。计算机版本与原始版本在基线时的平均得分差异不显著，从基线到终点所检测到的变化量在计算机版本与传统版本之间也未发现显著差异。77%的受试者认为计算机在基线时并未干扰他们的就诊，多数人（36%）更喜欢计算机，30%更喜欢临床医生，34%无偏好。到研究结束时，多数人（41%）无偏好，27%更喜欢计算机，32%更喜欢临床医生。结果支持将这些社交焦虑症的计算机管理症状评定量表作为临床医生管理版本的可行替代方案用于这类患者，这应为研究人员和临床医生提供一种评估社交恐惧症的可靠且具成本效益的方法。
