P02-140 - The REF Scale: a Good Indicator to Differentiate the Two Subtypes of Paranoia “Bad Me” and “Poor Me”?
Published online by Cambridge University Press: 17 April 2020
Abstract
Previously (Rodríguez-Testal et al., 2001) we analysed the multidimensionality of Referential Thinking Scale, obtaining similar results to original research of Lenzenweger et al. (1997) but warning about the construction of subscales.
In this study we intended to analyse if the REF Scale is a good indicator to differentiate the two subtypes of paranoia “Bad Me” and “Poor Me” (Trower & Chadwick, 1995).
Participants: We analyzed data from a different sample of previous studies with 326 participants (64.11% women, mean age 30.8, SD = 10.84), of whom 212 were patients.
Design, materials and procedure: We used the REF-scale (Lenzenweger et al., 1997) adapted to Spanish language, of which we deleted two items because of psychometric criteria, resulting 32 dichotomic items. We used SPSS 15.0 to conduct a principal-components factor analysis with a varimax and oblimin rotation, retaining two factors.
Two factors explained 31.32% of the variance (rotated solution). We interpreted factor through factor loadings higher than .42. Factor 1 accounted for 18.28% of the variance and it's associated with referential laughter, commentaries and guilt. Factor 2 accounted for 13.05% of the variance and it's associated with referential concerns related to the media.
Since the inter-factor correlation is moderate (.44) and there are no relevant clinical differences about the content between the two factors, the REF scale is a one-dimensional measure. Therefore, two big factors don’t emerge from the REF scale related to referential concerns about laughter-commentaries and guilt that correspond to “Poor Me” and “Bad Me”, respectively.
