Fumar representa 24% das mortes na população geral, sendo o fator que explica o maior número de anos de vida perdidos. É importante compreender as expectativas relacionadas ao comportamento de fumar. O presente estudo teve por objetivo validar o instrumento Short Form of the Smoking Consequences Questionnaire (S-SCQ) para uma versão brasileira. Após o processo de adaptação semântica para o idioma e contexto nacional o S-SCQ foi aplicado numa amostra de 129 pessoas. No passo seguinte, foram realizadas análises psicométricas para o conjunto de 21 itens. Os dados foram submetidos à prova de validade de construto por meio de Análise Fatorial Exploratória, com tratamento pairwise para casos omissos. Para proceder a Análise Fatorial se utilizou inicialmente o método da Análise dos Componentes Principais (ACP). Após, foi feita a Fatoração dos Eixos Principais (FEP) utilizando rotação Varimax com normalização de Kaiser. A fidedignidade da escala total (com 21 itens) apresentou índice alfa de Cronbach 0,851 e Lambda 2 de Gutmann 0,870. Índices bastante satisfatórios foram observados também nas subescalas. No mesmo sentido, os valores de correlação item-total também confirmaram os bons índices de fidedignidade da escala.

Abstract:
Smoking accounts for 24% of deaths in the general population and is also the factor that explains the biggest amount of years of life lost. It is important to understand the expectations regarding smoking behavior. The present study aimed to validate the Short Form of the Smoking Consequences Questionnaire (S-SCQ) for a Brazilian version. The Researchers did the process of semantic adaptation to language and national context. The S-SCQ was applied in a sample of 129 people. The next step was to perform psychometric analyses for the set of 21 items. Exploratory Factor Analysis, with pairwise treatment for missing cases, was used to achieve construct validity. To carry out Factor Analysis, the method of Principal Component Analysis (PCA) was used initially. Afterwards, Principal Axis Factoring (PAF) using Varimax rotation with Kaiser normalization was applied. The reliability of the total scale (21 items) showed a Cronbach alpha index of 0.851 and a 0.870 Lambda2 of Gutmann. Quite satisfactory rates were also observed in the subscales. Similarly, the item-overall correlation values also confirmed the scale’s good reliability indices.
