1. Methamphetamine Experience Questionnaire (MEQ)

Year: 2010

Developers:
Leamon, Martin H.; Flower, Keith; Salo, Ruth E.; Nordahl, Thomas E.; Kranzler, Henry R.; Galloway, Gantt P.

Description:
The Methamphetamine Experience Questionnaire provides useful information on drug use variables that contribute to paranoia commonly associated with methamphetamine use. The link between methamphetamine use and symptoms of paranoia is well-known, but separating it from paranoia attributable to other causes has been challenging. Since there are some similarities between cocain and methamphetamine use, the MEQ was adapted from the Cocaine Experience Questionnaire (CEQ) to assess lifetime methamphetamine-induced paranoia.

The MEQ is a structured interview comprising 50 items with a number of branch and skip points. The instrument first ascertains whether subjects ever experienced paranoia while using methamphetamine, and if so, inquires further about those experiences. The instrument assesses lifetime prevalence of paranoia. It inquires about lifetime symptoms, defines paranoia as a persecutory delusion, and emphasizes the difference between paranoia that occurs specifically during meth use and other types of paranoid experiences.

Population studied:Adults; Co-occurring clients
Instrument Type:Clinician-administered interview; Assessment
Administration/Scoring:Time needed for a clinician to administer the 50-item questionnaire is about 15 minutes.
Validity/Reliability:The MEQ has adequate test-retest and inter-rater reliability. The careful attention of trained interviewers to classifying experiences as paranoid or not and methamphetamine-induced or not increases the face validity of the MEQ.
