Validação e aferição de fidedignidade da versão brasileira da Compulsive Buying Scale

Abstract

Introdução: A Escala de Compras Compulsivas (CBS) é um instrumento breve e de fácil aplicação, que visa avaliar as principais dimensões do transtorno das compras compulsivas, centrando-se no controle dos impulsos. Objetivo: O presente estudo tem como objetivo validar e aferir a dedignidade da versão brasileira da Escala de Compras Compulsivas (CBS). Métodos: Para validade de construto, foi realizada análise fatorial com extração dos componentes principais e rotação Varimax. A correlação entre a escala CBS e as medidas de depressão e ansiedade, assim como do transtorno obsessivo-compulsivo, foi avaliada por meio do coe ciente de Pearson, para estudo da validade convergente e divergente. A consistência interna foi aferida por meio do coe ciente alfa de Cronbach. Resultado: A CBS apresentou bons parâmetros psicométricos, sendo considerada válida e dedigna em sua versão brasileira. No que concerne às correlações, a CBS apresenta uma correlação inversamente proporcional com outras escalas diagnósticas para o transtorno das compras compulsivas, indicando, portanto, ser um excelente instrumento de aferição dessa desordem. A CBS apresentou alto coe ciente alfa de Cronbach (0,86), demonstrando boa con abilidade. Conclusão: Embora seja uma escala curta, com poucos itens, a versão brasileira da escala de compras compulsivas apresenta boas propriedades psicométricas, apresentando--se como um importante instrumento para avaliação desse construto. AbstractBackground: e Compulsive Buying Scale is a short and easy-to-apply instrument, which comprises the main dimensions of the compulsive buying disorder, focusing on impulse control. Objective: is study aims to validate and assess the reliability of the Brazilian version of the Compulsive Buying Scale. Methods: To assess construct validity, a factor analysis with principal components extraction and Varimax rotation was conducted. e correlations between the CBS and measures for depression, anxiety, and obsessive-compulsive disorder were assessed with the Pearson coe cient, evaluating convergent and divergent validity. e internal consistency was measured using Cronbach's alpha coe cient. Result: e psychometric parameters of the Brazilian version of the CBS were satisfactory and the instrument was considered valid and reliable. e CBS showed an inversely correlation with other diagnostic scales for the compulsive buying disorder. Cronbach's alpha coe cient (0.86) was high, demonstrating a satisfactory reliability of the Portuguese CBS. Discussion: Although the Brazilian version of the Compulsive Buying Scale is a short version with just a few items, the scale has excellent psychometric properties, presenting itself as an important tool to detect and evaluate compulsive buying disorder.

Prevalence study of compulsive buying in a sample with low individual monthly income

“…In an American study, 65.5% of the sample recruited were women, 12 and in a German study women comprised 52.1% of the sample. 18 It was possible to detect that there was no statistically significant difference in the impact of compulsive buying between the sexes, although some studies have shown that women tend to be more affected by compulsive buying than men. 19 With regard to educational level, none of the participants were allocated to the high school or elementary school categories.…”

“…The degree of impairment associated with compulsive buying behavior was investigated using the Compulsive Buying Scale (CBS). 14,18 The CBS is a 7-item scale designed to assess compulsion in purchasing. The lower the score, the greater the likelihood of a compulsion to shop.…”

Cognitive function of Brazilian elderly persons: longitudinal study with non-clinical community sample

“…In this study, it were used the cut-off points suggested by the manual, subdivided as follows: 0 to 10: minimal symptoms, 11 to 19: mild, 20 a 30: moderate, and 31 to 63: serious. Regarding internal consistency, Cronbach's alpha was 0.90 (Cunha, 2001;Leite et al, 2012).…”
