A bio-behavioral model of addiction treatment: applying dual representation theory to craving management and relapse prevention

Two scales to evaluate cocaine craving

The cocaine craving questionnaire-brief (CCQ-Brief English) asks cocaine users to report their level of craving now. We constructed two brief scales of cocaine craving in a sample of 107 Spanish-speaking natives in treatment for cocaine abuse or dependence: the CCQ-Brief(Spanish) and the pictographic assessment of desire (PAD), which relies less on language. Principal component analyses yielded a one-component solution for the CCQ-Brief, explaining between 62% and 68% of the sample variability. Cronbach's alpha ranged from .92 to .94. The CCQ-Brief and the PAD were strongly correlated; effect sizes ranged from .42 to .68 in separate trials. Laboratory cue-exposure results showed that in both scales craving was higher upon presentation of cocaine-related rather than neutral pictorial stimuli. The CCQ-Brief and PAD are potentially valuable scales for evaluating cocaine craving.

A pilot study of a dual processing substance user treatment intervention with adults

This study responds to the identified need for evidence-based substance abuse interventions by examining the effects of an innovative dual processing substance use intervention aimed at decreasing the risk for substance relapse by targeting emotional regulation capacity. The study was completed in partnership with a Latino-serving community-based substance user treatment agency in a rural Northeastern region of the United States in 2005-2006 and was supported with pilot monies from the University at Albany School of Social Welfare NIDA-funded research center. The sample (N = 29) was comprised of adults with a diagnosis of substance dependence seeking treatment in an outpatient program. Study findings indicated that individuals who participated in the dual-processing treatment group decreased their craving with a trend toward increased self-efficacy over time in treatment and did not show treatment response differences across Latino and non-Latino clients, suggesting that treatment application was similar across these groups. The study's limitations are noted.
