Validation of the Personal Report of Confidence as Speaker in a Spanish clinical sample

The goal of this paper was to explore the psychometric properties of the PRCS-M (Personal Report of Confidence as Speaker-Modified; Bados, 1986) in a social phobic sample (N= 120). The 84.17% of the participants were women, with ages ranging from 17 to 48 (M= 24.06, SD= 5.16). Confirmatory factor analysis was calculated and we found that a bifactorial model adjusted quite well to data: positive statements (PRCS-MS) and negative statement (PRCS-MR). The internal consistency obtained was high (= .89). The PRCS-M correlated with both SSPS subscales (Self-Statements During Public Speaking) (SSPS-P r= -.50; SSPS-N r= .55), the SAD (Social Avoidance and Distress Scale) (r= .31), and the BFNE (Brief version of the Fear of Negative Evaluation Scale) (r= .35). Finally, there were significant differences (F [2, 115]= 7.72, p< .005) in the PRCS-M amongst the three social phobia subtypes (Heimberg, Holt, Schneier, Spitzer, & Liebowitz, 1993).
