Concordance among biological, interview, and self-report measures of drug use among African American and Hispanic adolescents referred for drug abuse treatment.

Abstract

This study examined the concordance among urine assays, interview measures, and self-report measures of marijuana and cocaine use among 190 drug-abusing/dependent African American and Hispanic adolescents and their families at 3 assessment points of an 18-month randomized clinical trial study. Results demonstrated concordance among urine assays, a calendar method self-report measure (Timeline Follow Back [TLFB]), and a noncalendar method self-report measure (Adolescent Drug Abuse Diagnosis Scale). Diagnostic criteria of marijuana and cocaine abuse/ dependence from a clinical structured interview (Diagnostic Interview Schedule for Children [DISC]) also converged, albeit weakly, with self-report measures. Adolescent and parent reports on DISC marijuana abuse/dependence diagnostic criteria were related; however, collateral findings for DISC cocaine abuse/dependence diagnostic criteria were equivocal. Differences in concordance among biological and self-report cocaine use measures were found for baseline TLFB assessments among African American participants. Implications for future use and refinement of adolescent drug use assessments are discussed.

Role of personality traits in cocaine craving throughout an outpatient psychosocial treatment program

“…This can lead to the perception (warranted or otherwise) that these outcome measures are less rigorous than biochemical ones. However, there seem to be discrepancies between self-reported cocaine use and urine assays at baseline, but not at follow-up assessments 39 ; e) our results cannot be extrapolated to women, given that other studies have already shown a significant effect of gender on craving experiences 40 ; f) only cocaine users who agreed to participate in this study were included. Hence, it is not clear whether these findings would apply to individuals who would refuse to participate in clinical studies or fail to meet the inclusion criteria; g) no other psychotherapeutic procedures or incentives were provided alongside CBT.…”

Testing for amphetamine-type stimulant (ATS) use to ascertain validity of self-reported ATS use among young female sex workers in Cambodia

“…However, study participants may misrepresent drug use due to social desirability bias, stigma, poor recall, poorly worded questions, or poorly worded response categories in surveys and interviews [23,24], all of which could result in misclassification of measured exposures. Although studies have shown that the use of Audio Computer-Assisted Self Interview (ACASI) increases reporting of sensitive and stigmatized behaviors [25,26], research suggests that the validity of self-reported drug use varies by population [27], race/ ethnicity [28][29][30], mental health [27], and drug treatment status [22,31,32], although not by gender [30,33]. Accuracy has varied in studies of arrestee populations [34,35] but have been reported as higher in groups sampled in emergency department and STI clinics [34].…”

Testing Cross-Sectional and Prospective Mediators of Internalized Heterosexism on Heavy Drinking, Alcohol Problems, and Psychological Distress Among Heavy Drinking Men Who Have Sex With Men

“…The TLFB demonstrates good agreement with collateral reports (Dillon et al, 2005) and convergent validity (Vinson et al, 2003). For this study, percentage of heavy drinking days (PHDD) within the month was calculated for each of the months preceding each assessment.…”
