Evidence supports the use of brief psychosis-spectrum screeners for identifying individuals at risk for psychosis. Screening has not been well-studied in help-seeking college samples. This study investigated the use of the Behavior Assessment System for Children, Second Edition (BASC-2) Atypicality Scale as a psychosis-spectrum screening tool within a university counselling centre.
Atypicality scores from the BASC-2 were compared to interview-based assessment, the Structured Interview for Psychosis-risk Syndromes (SIPS), to explore associations across the measures and evaluate the scale's ability to identify individuals who meet criteria for a psychosis-spectrum diagnosis.
Forty-three participants completed the BASC-2 and SIPS, and 23 were SIPS-positive. Compared to the SIPS-negative group, the SIPS-positive group had significantly higher Atypicality scores. Exploratory results indicated that Atypicality scores identified SIPS-positive individuals with an overall accuracy of 72% (78% sensitivity, 65% specificity).
The Atypicality Scale may be an appropriate first-line psychosis-spectrum screening tool in college counselling centres.
有证据支持使用简短的精神病谱系筛查工具来识别有精神病风险的个体。在寻求帮助的大学生样本中，对筛查的研究还不够充分。本研究在大学咨询中心调查了使用第二代行为评估系统（BASC-2）异常量表作为精神病谱系筛查工具的情况。
将 BASC-2 的异常分数与基于访谈的评估，即精神病风险综合征结构化访谈（SIPS）进行比较，以探索这些测量方法之间的关联，并评估该量表识别符合精神病谱系诊断标准的个体的能力。
43 名参与者完成了 BASC-2 和 SIPS，其中 23 名是 SIPS 阳性。与 SIPS 阴性组相比，SIPS 阳性组的异常分数显著更高。探索性结果表明，异常分数识别 SIPS 阳性个体的总准确率为 72%（敏感性为 78%，特异性为 65%）。
在大学咨询中心，异常量表可能是一种合适的精神病谱系一线筛查工具。
