Estrutura fatorial da versão brasileira da escala razões para fumar modificada

Abstract

Objective. To characterize the factorial structure and psychometric properties of the Brazilian version of the Modified Reasons for Smoking Scale (MRSS). MethOds. The sample consisted of 311 smokers (214 male; mean age: 37.6 ± 10.8 years), who came to Hemocentro de Ribeirão Preto to donate blood. Volunteers answered 21 items of the Brazilian version of the MRSS, Fagerström test, and the Brazilian Criterion of Economic Classification. Scores of MRSS items were evaluated based on their grouping, employing exploratory factorial analysis. The influence of clinical features over the final factorial solution scores was also investigated. Results. Factorial analysis led to the characterization of seven factors: dependence, stimulation, pleasure to smoke, hand-mouth activity, social interaction, tension reduction/relaxation, and habit/ automatism. Four questions were excluded due to factorial loadings below 0.3. The final version was made up of 17 items showing a minimal factorial loading of 0.376. Women showed high scores in dependence (3.5 X 3.1), tension reduction/relaxation (4.1 X 3.5), and hand-mouth activity (2.4 X 2.0). Lower Fagerström test scores were associated to low scores in dependence, tension reduction/ relaxation, habit/automatism and stimulation. cOnclusiOn: The Brazilian version of the MRSS, comprised of 17 items, showed satisfactory factorial structure and psychometric properties.

Cessação de tabagismo: desafios a serem enfrentados

“…The actual clinical usefulness of its administration in programs and actions aimed at smoking cessation still need to be demonstrated. The validation for the Portuguese language 8 and the consistent data regarding its use, as demonstrated in the study by Souza et al,7 open this opportunity to Brazilian researchers.…”

“…Also in the current issue of the journal, Souza et al 7 present a study using the Brazilian version of the Modified Reasons for Smoking Scale, comprising 21 structured questions grouped in several different combinations that characterize seven motivational domains associated with smoking. This is the first Brazilian study to be published using this scale, which has been recently validated for the Portuguese language by the same authors.…”

“…The reasons for smoking scale used by Souza et al, 7 as stated by the authors, has been rarely used outside the United States, and few studies on its use have been published even in the United States. The actual clinical usefulness of its administration in programs and actions aimed at smoking cessation still need to be demonstrated.…”

“…The following are the most important ones: Physicians Health Study (PHS), Women's Health Study (WHS), Honolulu Heart Study, Nurses Health Study, MONICA (Monitoring Trends and Determinants in Cardiovascular Disease), and Cardiovascular Health Study. 7 Based on such evidence, CRP was included in the 4th Brazilian Guideline of Atherosclerosis Prevention as a risk aggravator, that is, high CRP levels could cause an increase in the cardiovascular risk and change the treatment goals. 3 Ridker et al suggested the inclusion of CRP in a clinical score (Reynolds Risk Score) in order to improve the stratification of cardiovascular risk.…”
