- Cultural adaptation and Rasch psychometrics of the Substance Addiction Consequences scalePublication . Boska, Gabriella; Seabra, Paulo; Ferreira De Oliveira, Márcia Aparecida; Garcia Claro, Heloísa; Fernandes, IvanThis study aims to adapt and evaluate the validity of the Substance Addiction Consequences scale for the Brazilian community-based addiction setting. This is a psychometric study, conducted in two stages: (1) cultural adaptation and (2) validation using the psychometric Rasch model. The Substance Addiction Consequences derived from the Nursing Outcome Classification comprises 16 items and four domains in the original instrument. We applied the original scale with 200 outpatients at two Psychosocial Care Centers for Alcohol and Drugs in São Paulo, Brazil. The four subscales are suitable for the Rasch model. In 13 of the 16 items, infits and outfits are between 0.5 and 1.5, corresponding to the model's optimal parameters. In addition, we removed one item that distorted the measurement. The psychometrics suggested that the SAC scale is valid with its 15 items and four domains. Therefore, it can be considered appropriate to use in the Brazilian community-based addiction setting.
- Cultural adaptation and validation of the attitudes towards alcohol scale for health professionals in PortugalPublication . Seabra, Paulo; Robalo Nunes, Inês; Henriques Silva, Vanessa Alexandra; Valentim, Olga; Guedes De Pinho, Lara; Moutinho, Lidia; VARGAS, D; Curado, Maria Alice dos SantosWe aimed to conduct an adaptation and validation of the Attitudes towards Alcohol, Alcoholism and Individuals with Alcohol Use Disorders Scale (EAFAA) which set to address the main groups of attitudes. It is composed in its original version by 50 items, divided into 4 factors: (1) work and interpersonal relationships with patients with alcohol consumption disorders; (2) the person with alcohol consumption disorders; (3) alcoholism (aetiology) and (4) alcoholic beverages and their use. The cultural adaptation from Brazilian to European Portuguese changes 22 items and the designation of one factor. The content validity index scale was 0.96. The psychometric properties were analysed through a cross-sectional study, with a convenience sample of 500 health professionals and students. The confirmatory factor analysis model with the same four (4) original factors, led to the elimination of 9 items. The scale revealed Cronbach’s alpha of 0.801. Empirical adjustment indices were satisfactory with Minimum Discrepancy Function by Degrees of Freedom divided (CMIN) ( X2/gl) = 3.91; p < 0001, RMSEA = 0.076 and the goodness of fit index (GFI) with 0.8. Relative indices values were normal fit index (NFI) = 0.6, comparative fit index (CFI) = 0.7 and Tucker-Lewis index
