The validity and reliability of the Mandarin Chinese version of the drug abuse screening test among adolescents in Taiwan

Development and Validation of an Arabic Version of the Drug Abuse Screening Test-10 (DAST-10) among Saudi Drug Abusers

The Drug Abuse Screening Test-10 (DAST-10) is a valid and reliable screening tool for drug use-related problems, however there is no Arabic version. To our knowledge, this is the first study to develop and validate an Arabic DAST-10 version. Saudi young adults participated in the study as two groups; drug users (n=360) recruited from Alamal Complex for Mental Health, Jeddah, and drug non-users (n=100). Three measures were used: (1) Demographic and drug use description questionnaire, (2) Arabic DAST-10 version, and (3) Urine analysis for drug use. The developed Arabic DAST-10 version demonstrated adequate internal consistency. High correlations were shown between its scores and the two standard measures (urine analysis and self-reporting question) indicating good criterion validity. Sensitivity and specificity values were between 91.5 - 99.7% and 57 - 92.5% with different DAST-10 cutoff values. An optimal performance at a cutoff score of 3 or more was most likely to significantly identify drug users. Discriminant analysis showed that more than 90% of cases were correctly classified. Distribution of participants in categories of DAST-10 scores according to degree of problems was reasonable. It is concluded that the developed Arabic DAST-10 version is a reliable and valid screening tool for drug use-related problems in Arabic speakers.

Screening illicit substance use in college students: The Chinese version of the Drug Abuse Screening Test

BACKGROUND

This study investigated the applicability of the Chinese versions of Drug Abuse Screening Test (DAST) to detect illicit substance use in college students.

METHODS

The data arising from a campus prevention program, Screening for Illicit Substance Use in College (SISUC), were utilized to explore the psychometrics of 26 items (DAST-26) and 10 items (DAST-10) versions of DAST in college students (CS group). A group of youth with illicit substance use were enrolled as the Illicit Substance Use group (IS group). A set of self-report questionnaires, including the Chinese version of DAST, were administered.

RESULTS

A total of 1214 participants were recruited as the CS group and 208 as the IS group. The Cronbach's alpha of DAST-26 was 0.74 in CS and 0.90 in IS; while 0.59 in CS and 0.78 in IS for the DAST-10. At a cut-off of 4 for DAST-26, the sensitivity was 87 % and specificity 97 %. As to DAST-10, a cut-off of 2 produced the sensitivity of 86 % and specificity of 96 %. The area under the curve was 0.943 for DAST-26 and 0.940 for DAST-10. The confirmatory factor analyses found a single-factor solution for the DAST-26 and DAST-10.

CONCLUSIONS

With comparison to the DAST-26, the shorter version, DAST-10, may offer promise for detecting illicit substance use in college students.

Posttraumatic stress symptoms, shame, and substance use among Asian Americans

BACKGROUND

To examine the association between posttraumatic stress symptoms (PTSS) and substance use among Asian Americans and the influence of a culturally-relevant moderator, shame.

METHODS

From 2016 to 2017, 199 participants from Amazon Mechanical Turk and a university subject pool completed an online survey. Chi-square and Kruskal-Wallis tests explored demographic and clinical differences among three Asian American ethnic subgroups (East Asians, South Asians, and Southeast Asians). Generalized linear models assessed the association between PTSS and substance use (alcohol, tobacco, and other drugs) and the moderation of this relationship by shame.

RESULTS

Ethnic subgroups significantly differed on all three substance use variables. The severity in PTSS was significantly associated with hazardous drug use (IRR = 1.03, (1.01, 1.05), p = .003). The association between PTSS and days of tobacco use and binge drinking was significantly moderated by shame. Low levels of shame increased the effect of PTSS on binge drinking (IRR = 1.05, (1.00, 1.10), p = .035) and tobacco use (IRR = 1.15, (1.11, 1.19), p < .001). High levels of shame had no effect of PTSS on binge drinking (IRR = 1.01, (0.99, 1.03), p = .54) and a reduced effect on tobacco use (IRR = 1.07, (1.05, 1.09), p < .001).

CONCLUSIONS

Among Asian Americans, the association of PTSS and substance use depends on shame. Lower levels of shame are a risk factor, increasing the effect of PTSS on substance use. Culturally-modified addiction treatments should assess for shame among Asian Americans and attend to ethnic sub-group diversity in substance use.
