Although a potentially useful measure, to date, there has been only one published test of the psychometric properties of the Mini-Social Phobia Inventory (Mini-SPIN). Therefore, the psychometric properties of the Mini-SPIN, a brief 3-item screen for social anxiety disorder, were examined.
Participants were 186 patients diagnosed with social anxiety disorder (DSM-IV criteria) attending a specialized anxiety disorders clinic for treatment, and 56 nonclinical participants were recruited to serve as comparisons. Participants were diagnosed using the Anxiety Disorders Interview Schedule for DSM-IV, and they also completed the Mini-SPIN, the Social Interaction Anxiety Scale (SIAS), and the Social Phobia Scale (SPS). Construct validity for the Mini-SPIN was assessed by its correlations with the SIAS and the SPS. Reliability, internal consistency, discriminant validity, and sensitivity to change were also examined, and receiver operating characteristic curve analysis was conducted to determine guidelines regarding cutoff scores for the Mini-SPIN. The study was conducted between April 1999 and December 2001.
Supporting findings from a previous study, strong support was found for the Mini-SPIN's ability to discriminate individuals with social anxiety disorder from those without the disorder. Receiver operating characteristic analysis revealed that using a cutoff score of 6 or greater (P < .001), the Mini-SPIN demonstrates excellent sensitivity, specificity, and positive and negative predictive values.
Findings suggest that the Mini-SPIN is a reliable and valid instrument for screening social anxiety disorder in adults. Importantly, the use of the Mini-SPIN in primary care may be one way to address the underrecognition of social anxiety disorder in such settings. Due to the ease and brevity of the measure, it also shows potential for use in epidemiology. Given that this study has revealed the ability of the Mini-SPIN to reflect treatment change, the Mini-SPIN may also be considered for use in treatment outcome studies that specifically require minimal assessment.
尽管《简易社交恐惧症量表》（Mini-SPIN）可能是一项有用的测量工具，但迄今为止，关于其心理测量学特性的已发表测试仅有一项。因此，本研究对用于社交焦虑障碍筛查的简易3条目量表Mini-SPIN的心理测量学特性进行了检验。
研究对象包括186名在专门的焦虑症诊所接受治疗、符合社交焦虑障碍（DSM-IV标准）诊断的患者，以及56名招募的非临床参与者作为对照。使用《DSM-IV焦虑症访谈量表》对参与者进行诊断，他们还完成了Mini-SPIN、社交互动焦虑量表（SIAS）和社交恐惧症量表（SPS）。通过Mini-SPIN与SIAS和SPS的相关性评估其结构效度。同时还检验了信度、内部一致性、区分效度以及对变化的敏感性，并进行了受试者工作特征曲线分析，以确定Mini-SPIN的临界值标准。本研究于1999年4月至2001年12月期间进行。
支持了先前一项研究的结果，发现Mini-SPIN在区分社交焦虑障碍患者与非患者方面具有很强的能力。受试者工作特征分析显示，使用临界值6或更高（P <.001）时，Mini-SPIN具有出色的敏感性、特异性、阳性和阴性预测值。
研究结果表明，Mini-SPIN是一种可靠且有效的工具，可用于筛查成人社交焦虑障碍。重要的是，在初级保健中使用Mini-SPIN可能是解决此类环境中社交焦虑障碍未被充分认识的一种方法。由于该测量方法简便且简短，它在流行病学研究中也显示出应用潜力。鉴于本研究揭示了Mini-SPIN反映治疗变化的能力，在专门要求最小化评估的治疗结局研究中也可考虑使用Mini-SPIN。
