Inventario de supresión del pensamiento del “oso blanco” (WBSI): Propiedades psicométricas de la versión portuguesa (Portugal)

Abstract

Resumen: El White Bear Suppression Inventory (WBSI) fue concebido para evaluar tendencia a la supresión de pensamientos. En el presente estudio se aplicó, junto con otras medidas, a una muestra de 558 sujetos de la población no clínica portuguesa para el estudio de su estructura factorial y propiedades psicométricas. Se sometieron a análisis factorial confi rmatorio (AFC) cinco modelos con estructuras unidimensionales, bidimensionales y tridimensionales. Los resultados mostraron un factor con una adecuada consistencia interna y estabilidad temporal α = .88, CCI = .61 [IC95% = .31-.78]). La escala obtenida mostró asociaciones con medidas psicológicas y psicopatológicas presentando una adecuada validez convergente. Se presentan los datos normativos para la muestra analizada. Se concluye que la versión portuguesa del WBSI se presenta como un instrumento adecuado para su utilización en Portugal.Palabras clave: WBSI; supresión de pensamiento; análisis factorial exploratorio y confi rmatorio; fi abilidad; validez. The White Bear Suppression Inventory (WBSI): Psychometric properties of the Portuguese (Portugal) versionAbstract: The White Bear Suppression Inventory (WBSI) was developed to measure the tendency to suppress unwanted negative thought. With the aim to study its internal structure and psychometrics properties, this inventory was applied with other measures to a sample of 558 participants from the general non-clinical Portuguese population. We performed confi rmatory factorial analyses (AFC) to test fi ve models of unidimensional, bi-dimensional and three-dimensional structures. The results yielded the existence of one single factor with adequate levels of internal consistency and temporal stability (α = .88, CCI = .61 [IC95% = .31-.78]).The WBSI was associated with psychological and psychopathological measures showing adequate levels of convergent validity. We present the normative data for the analyzed sample. In conclusion, the Portuguese version of the WBSI is an adequate instrument to be used in Portugal.

Pathological Worry in Portugal: The Portuguese Version of the Penn State Worry Questionnaire (PSWQ)

“…The White Bear Suppression Inventory (WBSI) (Wegner & Zanakos, 1994; Portuguese version by Jiménez-Ros, Orgambídez-Ramos, & Pascual, 2015) is a 15-item self-report instrument to measure people’s general tendency to suppress unwanted thoughts. Items are rated on a 5-point scale from 1 ( strongly disagree ) to 5 ( strongly agree ).…”

Do Trait Emotional Intelligence and Dispositional Mindfulness Have a Complementary Effect on the Children’s and Adolescents’ Emotional States?

“…It contains statements such as "There are things I prefer not to think about" or "I always try to put problems out of mind." The WBSI has demonstrated high internal consistency in Spanish (and Portuguese) samples (Ros et al, 2015). This inventory is an indicator of the frequency individuals have intrusive and ruminative thoughts and has been found to correlate positively with depressive symptoms, anxiety, and obsessive-compulsive behavior (Wegner and Zanakos, 1994).…”

White Bears, Chronic Worriers, and the Need to Distinguish Thought Suppression from Intrusive Thoughts

“…While this is common practice in social and personality psychology, it has also been criticised in terms of the representativeness of such samples (Visser et al, 2000). Second, it should be noted that, in line with previous findings (Jiménez Ros et al, 2015;Luciano et al, 2006), none of the hypothesised WBSI models had good fit, so that modifications had to be made upon one of these models (i.e. the analysis was not strictly confirmatory).…”

“…One possible exception is the study conducted by Blumberg (2000), who identified three instead of two factors: UIT, TS, and self-distraction. Furthermore, some authors even defend the original unidimensional model (Altın & Gençöz, 2009;Jiménez Ros et al, 2015;Muris et al, 1996;Palm & Strong, 2007;Vincken et al, 2012). All in all, there does not seem to be a clear, definite structure of the WBSI, and none of the proposed models shows good fit (Jiménez Ros et al, 2015;Luciano et al, 2006).…”
