- Aims The Children of Alcoholics Screening Test (CAST-6) is a brief screening instrument developed to identify children with parents having problematic alcohol use. The aim of this study was to evaluate the psychometric properties of the CAST-6 among adolescents aged 15-18 years, and also to identify an optimal cut-off score for this age group. Methods A total of 3000 15 to18 year-olds were randomly selected from a register of postal addresses in Sweden. An invitation letter, including access information to the electronic questionnaire, was sent out by regular mail and 1450 adolescents responded with baseline data. Test-retest reliability within a 2-3-week period was calculated based on the 111 respondents who answered the same questionnaire twice. To determine an optimal cut-off score, a small treatment-seeking sample (n = 22) was recruited from a support group agency to be used as a reference group. Results The six items of the CAST-6 screening test loaded onto one latent factor with good internal consistency (alpha = 0.88), and excellent test-retest reliability (ICC = 0.93, 95% CI 0.90-0.95). The optimal cut-off score among adolescents was 2 points with a sensitivity of 55% and specificity of 79% (AUROC = 0.71, 95% CI 0.58-0.83). Conclusions The CAST-6 has good to excellent psychometric properties among adolescents. The identified optimal cut-off score of 2 points should be treated with caution due to study limitations. The CAST-6 can be used in various settings to identify a vulnerable at-risk group of children and adolescents that may be in need of support.

- <b><i>Background/Aims:</i></b> Not enough is known about the psychometric properties of screening instruments for problematic alcohol consumption among adolescents. The aim of the current study was to evaluate and compare the performance of the screening instruments: Alcohol Use Disorders Identification Test (AUDIT), AUDIT-C, CRAFFT, and the alcohol domain of Alcohol, Smoking and Substance Involvement Screening Test-Youth (ASSIST-Y) among adolescents and to suggest optimal cut-offs indicating problematic use. <b><i>Methods:</i></b> Data was collected from a general population sample (<i>n</i> = 1,421) and a treatment-seeking sample (<i>n</i> = 59) using electronic versions of the instruments. <b><i>Results:</i></b> The internal consistencies for the instruments were fair (alpha’s AUDIT 0.74, AUDIT-C 0.75, CRAFFT 0.67, ASSIST-Y 0.62), and test-retest reliabilities were good to excellent (intraclass correlation coefficients AUDIT 0.86, AUDIT-C 0.93, CRAFFT 0.77, ASSIST-Y 0.63). The CRAFFT and ASSIST-Y demonstrated reasonable construct validities while factor solutions for AUDIT and AUDIT-C could not be determined. The optimal cut-off score was 2 for both CRAFFT and ASSIST-Y (61 and 73% sensitivities and 79 and 65% specificities, respectively), while sensitivity scores were poor for AUDIT and AUDIT-C. <b><i>Conclusion:</i></b> Based on the current sample, ASSIST-Y and the CRAFFT performed better than AUDIT and AUDIT-C. Health-care clinics working with adolescents should carefully consider their choice of screening instruments.
