title: SPINning factors: factor analytic evaluation of the Social Phobia Inventory in clinical and nonclinical undergraduate samples.
abstract: The Social Phobia Inventory (SPIN) was designed to assess three dimensions of social anxiety (i.e., fear, avoidance, and physiological arousal) as posited by the scale authors (Connor et al., 2000). Despite expectations of a 3-factor solution, analyses of the SPIN to date have provided support for 3- and 5-factor solutions (Radomsky et al., 2006). Moreover, a 3-item version, the Mini-SPIN (Connor et al., 2001), has good sensitivity and specificity for generalized social anxiety disorder (SAD), implying some item redundancy. Another recent psychometric analysis of the SPIN was performed in a diagnostically diverse clinical sample (Antony et al., 2006); however, the study did not include a comprehensive evaluation of the factor structure. The current study was designed to comprehensively assess the SPIN factor structure using exploratory (EFA) and confirmatory (CFA) factor analyses in undergraduate (N=227) and clinical samples (N=355) using current recommendations for factor analyses (Osborne et al., 2008). Results suggest a 10-item 3-factor solution may be an ideal fit for clinical samples; however, using the undergraduate sample, the same solution was significantly better than precedent solutions but nonetheless not ideal. Implications and recommendations for future research are discussed.
