Objective: To report the development and validation of the Crack Use Relapse Scale (CURS) in an inpatient population. Methods: A pilot study with 30 male crack users was conducted to generate 35 sentences related to the construct of interest. A five-point Likert scale including 25 items and, initially, nine theoretical factors was generated and utilized in a cross-sectional study with a sample of 333 hospitalized male crack users. Results: Overall Cronbach's alpha was a = 0.86. The exploratory factor analysis (EFA) with oblimin rotation kept the 25 items (factor loadings . 0.40) and six definitive factors, which explained 62.1% of the total variance.
Conclusions:The six-factor model yielded by the EFA of the CURS reflects the various dimensions of the construct, assigning satisfactory values and demonstrating good psychometric properties, including validity and reliability.
Background: When it comes to crack/drug use, relapse is a relatively common event in the first weeks after the end of treatment. However little is known about what happens to patients who relapse after discharge. Objective: To report the confirmatory factor analysis (CFA) of the Crack Use Relapse Scale (CURS) in an inpatient population. Methods: A five-point Likert scale with 25 items and, initially, 9 theoretical factors was generated and utilized in a cross-sectional study with a sample of 333 hospitalized male crack users. Results: CFA indicated a well-fitting model for the CURS. Discussion: The CFA shows that the CURS model is appropriate and well-fitting for assessment of latent variables common to psychiatric and psychological constructs -in this case, relapse of crack cocaine use after inpatient treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
