Background/Aims: 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. Methods: Data was collected from a general population sample (n = 1,421) and a treatment-seeking sample (n = 59) using electronic versions of the instruments. Results: 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. Conclusion: 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.

Aims: The present study examined the prevalence of Swedish children living with at least one parent whom has a substance use disorder (SUD), i.e. either an alcohol use disorder (AUD) or a drug use disorder (DUD). Methods: A 2013 cross-sectional survey of a nationally representative sample (n = 15,576) of the Swedish adult population 17–84 years of age was used. The response rate was 59.3%. SUDs were measured using selected parts of the Mini International Neuropsychiatric Interview (MINI), derived from the 4th edition of the diagnostic and statistical manual of mental disorders (DSM-IV). In total, 3778 parents with 7448 children under the age of 18 years participated. Results: The proportion of children whose parent had a SUD was 4.6%, implying that around 90,000 children in Sweden experience this situation. Having a parent with an AUD was most common (3.7%), while 0.7% and 0.2% had a parent with a DUD and both (AUD plus DUD), respectively. Conclusions: Our results showed that a substantial number of children in Sweden have parents with a SUD and that it is important to consider both alcohol and drugs, when estimating the size of this group. Our findings call for further strategies to support these children and their families.

Aims: The primary aim is to estimate the prevalence of Swedish adolescents who perceive their parent(s) to have alcohol problems. Additional research questions pertain to the prevalence of adolescents who think someone close to them drinks too much alcohol and if this has hurt them or caused them problems. Methods: A cross-sectional design was employed using a web-based survey targeted to 1000 Swedish 16–19-year-olds randomly selected from a web panel. The questionnaire included the CAST-6 scale, used to assess whether or not participants perceived their parents’ alcohol consumption as problematic, and questions relating to whether or not they think someone close to them drinks too much and if this has caused them problems. Data was weighted using a post-stratification procedure. Results: The proportion of adolescents classified as having parents with alcohol problems was 20.1%. Further, 44.0% reported that they think someone close to them drinks too much alcohol and 9.6% that this has hurt them or caused them problems. Conclusions: These results indicate that the problem is widespread. Our findings are similar to previous research where a more indirect methodology has been adopted, using either psychiatric interviews or self-reported alcohol consumption of adults, to estimate the magnitude of the problem.

Aims: The Alcohol Use Disorders Identification Test (AUDIT) is a well-established and widely used screening instrument. It has been shown that AUDIT has good criterion validity in relation to alcohol abuse and dependence according to DSM-IV, but it has not yet been validated following the introduction of the DSM-5 diagnostic system. The aim of this study was to evaluate concurrent validity for the AUDIT in relation to self-reported DSM-5 severity levels for Alcohol Use Disorder (AUD) in a Swedish general population sample. Methods: A postal questionnaire, containing the AUDIT and the 13-item brief DSM-5 AUD diagnostic assessment screener, was sent to a random sample of 1,500 persons drawn from the Swedish population, aged between 17 and 80 years and having a public residence address in Sweden. To evaluate the concurrent validity of AUDIT in relation to DSM-5 severity criteria for AUD, a Receiver Operating Characteristics (ROC) curve analysis was conducted. Results: Area under the curve (AUROC) showed excellent differentiation between AUD or not, mild (.93), moderate (.92) and severe (.99). Higher individual AUDIT scores were associated with more severe levels of AUD according to the DSM-5 screener. The optimal cutoff scores approximate earlier research on the DSM-IV and were identified as 5, 7 and 13 points, respectively, for mild, moderate and severe AUD. Conclusions: Our findings indicate that AUDIT is a valid screener for detecting concurrent AUD at three severity levels in the Swedish general population.
