The validity of self-reported cocaine use in two groups of cocaine abusers.

Abstract: To evaluate the validity of 2 self-report methods for estimating cocaine use, Timeline Follow-Back (TLFB) and weekly calendar reports from 65 patients with a cocaine use disorder were compared with urine drug test results. The TLFB showed fair to moderate validity, and the weekly calendar showed moderate to high validity in measuring the frequency of cocaine use. Similar results were obtained when the self-report measures were used to time specific cocaine use episodes. In addition to evidence for superiority … Show more

“…This study extends previous investigations of drug abuse/ dependence instruments (e.g., Ehrman & Robbins, 1994;Fals-Stewart et al, 2000;Hersh et al, 1999;O'Farrell et al, 2003;Sobell & Sobell, 1996;Winters, 1999) to African American and Hispanic adolescents referred to drug abuse treatment and their collateral parent reports.…”

“…Of the 481 missing urine specimens, 314 (65.2%) were self-reported by patients as positive for cocaine. These figures are comparable to previous studies using self-report data in cocaine dependent samples Hersh, Mulgrew, Van Kirk, & Kranzler, 1999;Zanis, McLellan, & Randall, 1994). This indicated that in this sample, self-reported cocaine use is relatively reliable.…”

“…Using these cutoffs, 23 urines were submitted that were positive for cocaine when the participant had denied cocaine use in the past 3 days, 31 were positive for marijuana when the participant had denied marijuana use in the past 7 days, and 9 were positive for opioids when the participant had denied opioid use in the past 3 days. This rate is consistent with previous studies of substance-dependent samples (43)(44)(45). Breathalyzer samples were also collected at each assessment visit; none indicated recent alcohol use.…”

“…Participants were administered the Structured Clinical Interview for DSM-IV (SCID)(41) prior to randomization to establish substance use and psychiatric diagnoses. The Substance Abuse Calendar, similar to the Timeline Follow Back (42,43), was administered weekly during treatment to collect detailed day-by-day self-reports of drug and alcohol use throughout the 56-day treatment period as well as for the 28-day period prior to randomization.…”
