RESUMEN

BACKGROUND AND AIMS: For most treatment-seeking patients with severe Alcohol Use Disorder (AUD), abstinence is the clinically indicated goal. Existing AUD motivation scales are non-specific about treatment consumption goals, which limit their effectiveness. Desires and mental imagery are relevant in the motivation for AUD treatment engagement. The Motivational Thought Frequency Scale for an abstinence goal (MTF-A) was adapted from the MTF for controlled drinking (MTF-CD). This study psychometrically evaluated the MTF-A in an alcohol-dependent sample engaged in treatment with a goal of abstinence. To enhance the clinical utility of the scale, a secondary aim was to evaluate a psychometrically equivalent short version of the MTF-A. METHOD: A sample N of 329 treatment-seeking patients with AUD (mean age of 44.44 years, SD = 11.89 years, 72% male) who were undertaking a cognitive behavioral treatment (CBT) program for abstinence completed the Motivational Thought Frequency Scale for Abstinence (MTF-A) and the Severity of Alcohol Dependence Questionnaire (SADQ). The MTF-A measured motivation for abstinence through four factors: intensity, self-efficacy imagery, incentives imagery, and availability. Confirmatory factor analyses (CFAs) were conducted to examine factor structure and model fit. Cronbach's alpha assessed internal consistency. Predictive validity was determined by logistic regression predicting first-session treatment non-attendance and alcohol consumption between baseline assessment and commencement of treatment, controlling for potential confounds. RESULTS: A four-factor structure provided the best fit for the MTF-A, compared with one- and three-factor models. A shortened 9-item MTF-A scale (S-MTF-A) provided better fit than the 13-item MTF-A scale. Both MTF-A and S-MTF-A displayed good internal consistency. Although both MTF-A and S-MTF-A successfully predicted first-session treatment non-attendance, neither predicted alcohol consumption between the baseline assessment and commencement of treatment. CONCLUSIONS: The model fit of the four-factor, 9-item S-MTF-A was superior to the original 13-item MTF-A. Both scales were predictive of participation of AUD treatment. Desires and mental imagery play an important role in AUD treatment motivation.

RESUMEN

AIMS: To develop a measure of craving based on the Elaborated Intrusion (EI) theory of desire and to examine the construct, concurrent and discriminant validity of the instrument. DESIGN: Cross-sectional. SETTING AND PARTICIPANTS: Patients from a hospital alcohol and drug out-patient service (n = 230), participants in a randomized controlled trial (n = 219) and students in a university-based study of alcohol craving (n = 202) were recruited. MEASUREMENTS: The Alcohol Craving Experience questionnaire (ACE) was developed to measure sensory aspects of craving (imagining taste, smell or sensations of drinking and intrusive cognitions associated with craving) when craving was maximal during the previous week (ACE-S: strength), and to assess frequency of desire-related thoughts in the past week (ACE-F: frequency). All participants completed the ACE and the Alcohol Use Disorders Identification Test (AUDIT). The Obsessive Compulsive Drinking Scale (OCDS) and the Depression Anxiety and Stress Scale (DASS) were completed by hospital patients and randomized control trial participants. FINDINGS: Exploratory factor analysis on the ACE-S and ACE-F resulted in a three-factor structure representing imagery, intensity and intrusion. An attempt to confirm this factor structure required a reduction in items (two from ACE-S, five from ACE-F) before a good fit to the three-factor model was obtained. Concurrent validity with the OCDS, with severity of alcohol dependence and with depression, anxiety and stress, was demonstrated. The ACE discriminated between clinical and non-clinical populations and between those at higher risk of alcohol dependence and those at lower risk. CONCLUSIONS: A new scale, the Alcohol Craving Experience questionnaire, based on the Elaborated Intrusion theory of desire appears to capture key constructs of the theory and correlate with indices of alcohol dependence.
