The goal of this article is to present evidence on the internal consistency and convergent validity of the Brazilian Portuguese versions of the Global Appraisal of Individual Needs-"Initial" and "Short Screener" versions., Methods: One hundred sixty-eight individuals from an inpatient service and/or a community-based outpatient service located in São Paulo were interviewed using the Brazilian Portuguese versions of the instruments. The internal consistency of the instruments scales was computed, along with evidence for the convergent validity between corresponding subscales of the Initial and Short Screener instruments., Results: Cronbach's alpha values for both instruments' total scale scores were greater than .7. The Short Screener scales showed strong-to-moderate correlations with corresponding subscales of the Initial. The General Individual Severity Scale from the Initial and Total Disorder Screener from the Short Screener have convergent validity with each other (ρ = 0.801)., Conclusions: The Brazilian Portuguese instrument scales showed evidence for internal consistency and convergent validity performing similarly to the American English versions., Competing Interests: The authors report no conflicts of interest. The authors alone are responsible for the content and writing of the article.

This 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.
