In previous works, referential thinking was predicted by clinical and dispositional variables such as social anxiety or vulnerability to depression (Rodríguez-Testal, Senín-Calderón & Fernández-Jiménez, submitted to revision).We propose to find personality variables to characterize the emergence of referential thinking. We predict a greater referential thinking in subjects with a high sensitivity to punishment and higher scores on social anxiety.Participants: 366 subjects selected from the general population, 66.6% women, mean age=33.18 (SD=12.79).We used the REF-scale (Lenzenweger et al., 1997) adapted to Spanish language, GHQ-28 (Goldberg, 1996), SPSRQ (Torrubia et al., 2001) and The Revised Self-Consciousness Scale (Scheier & Carver, 1985).It was applied a cross-sectional design and a correlation method. All the analysis were accepted at p<.05.The multiple linear regression analysis showed the importance of the clinical variable of depression, public self-consciousness, and sensitivity to reward and punishment as predictors of referential thinking (34% of the variance explained). The discriminant analysis according to scores in referential thinking was significant (Lambda=.87, p=.001). The combination of the above variables correctly classified 85.1% of cases.Subjects more concerned about how they are perceived by others tend to a greater presence of self-references, although they don’t show a high score in social anxiety. Susceptibility to reward and high vulnerable to punishment are the personality variables that best predicted referential thinking.
