title: Methamphetamine and alcohol abuse and dependence symptoms: associations with affect lability and impulsivity in a rural treatment population.
abstract: The present study examined associations between impulsivity and affect lability and methamphetamine and alcohol abuse and dependence symptoms in a rural inpatient treatment population (N=235). Thirty-two percent of participants reported methamphetamine use in the past 90 days prior to admission. Amphetamine use disorders were found to be more common among younger participants whereas alcohol use disorders were more common among older and Native American participants. After controlling for age, gender, use frequency, and injection use, impulsivity but not affect lability was associated with methamphetamine abuse but not dependence symptoms. Lability but not impulsivity was associated with alcohol dependence but not abuse symptoms after controlling for age, gender, and use frequency. Consistent with past epidemiological studies, results indicate that methamphetamine use is a prominent problem facing rural substance use treatment facilities. Affect lability and impulsivity are associated with methamphetamine and alcohol-related problems in this population.
