About

The object of this study is to develop a treatment for alcohol use disorders that is more effective than current CB treatments. Through a 2009 R-21 pilot project the investigators developed a cognitive-behavioral (CB) treatment that employed cellphone-based experience sampling (ES) to collect detailed patient data, in near real-time, and that used those data to direct treatment for each patient based on his/her pattern of drinking and specific coping actions during high-risk situations. ES data included momentary assessments of situations, thoughts and feelings antecedent to drinking episodes, and the use of coping skills. That initial study of the Individualized Assessment and Treatment Program (IATP) showed promise. The present study is intended to extend the earlier findings, to compare IATP to a more active control treatment, and to evaluate long-term outcomes.

Full description

An 2009 R-21 pilot project developed a cognitive-behavioral treatment for alcohol use disorders that employs cellphone-based experience sampling (ES) to collect detailed patient data in near real-time, and uses those data to direct treatment for each patient based on his/her specific patterns of drinking and specific coping actions during actual high-risk situations. ES data included situations, thoughts and feelings antecedent to drinking episodes, and any use of coping skills. The object was to create a CB treatment that was more relevant for each patient and more effective than current treatments. In the initial study the Individualized Assessment and Treatment Program (IATP) yielded better drinking rates at posttreatment, and more adaptive changes in coping, than a conventional manualized CBT program. Moreover, changes in drinking were partly mediated by pre-to-posttreatment changes in coping with high-risk situations. Questions unanswered included:

1. Because the pilot study only collected data pre- and posttreatment, with no follow-ups, it is not clear whether use of coping skills reduced drinking, or whether reduced drinking led to more adaptive coping.
2. It was not known which coping skills or other factors drive outcomes in the long-term.

To answer these and other questions the investigators proposed to enroll 207 patients in a full-scale trial of IATP with extended follow-ups to examine determinants of outcomes over time. IATP will be compared to a more conventional packaged CB treatment (PCBT), and to a Case Management Control condition (CaseM), in a dismantling design. In addition to coping, a number of other possible treatment mechanisms suggested by the literature will be examined, including motivation, self-efficacy, self-control, social support, alliance with the therapist, AA involvement, mindfulness, and utilization of other treatment services.

By specifically training coping skills for use in high-risk for drinking situations, the investigators will be able to assess how skills per se contribute to initiation and long-term maintenance of behavior change. The use of ES during treatment will allow a determination of what patients are actually doing, in close to real time, to initiate and maintain their own sobriety. The use of ES in the follow-up period will allow the investigators to determine whether coping skills that were active in initiation of reduced drinking continue to be active in the long-term, as well as the extent to which other mechanisms may come into play. In this way investigators can develop a clearer picture of the processes that affect outcomes of CBT, and will enable clinicians to focus more precisely on the most relevant mechanisms of change. Comparing IATP with PCBT will test effects of tailoring skills. The use of CaseM will control for the general effects of study participation (i.e., "common factors"), especially therapist support. The study builds on pilot data and on procedures that have already been developed but not fully tested. This would be the first study to evaluate effects of treatment on actual behaviors and cognitions in high-risk situations as they occur.

Individualized Assess & Treatment (IATP)

Experimental group

Description:

Intervention: Cognitive-Behavioral IATP consists of 12 weekly visits of individual treatment. IATP employs cellphone-based experience sampling via interactive voice response (IVR) to assess drinking, plus craving, thoughts, feelings, and coping behaviors to develop near a real-time picture of patients' high-risk situations and the ways they use to deal with them. This information will be used by the therapist and client together to problem-solve and devise adaptive coping responses to these specific high-risk situations, and develop generalized solutions to deal with other situations in the future.

Treatment:

Behavioral: Individualized Assess & Treatment (IATP)

Packaged Cognitive-Behavioral (PCBT)

Active Comparator group

Description:

Intervention: Cognitive-Behavioral PCBT consists of 12 weekly visits of individual treatment. PCBT is designed to remediate deficits in skills for coping with interpersonal (e.g., social pressure, conflict with others) and intrapersonal (e.g., craving, anger) antecedents to drinking. The treatment consists of 6 mandatory modules (e.g., managing cravings) plus 6 electives from a list of 10 (e.g., receiving criticism; scheduling pleasant activities).The treatment, based on manuals developed for our previous clinical research provides a structured experience using didactic presentations, behavioral rehearsal, and homework practice exercises.

Behavioral: Packaged Cognitive-Behavioral (PCBT)

Case Management (CaseM)

Active Comparator group

Description:

Intervention: Social and Instrumental Support CaseM is included to control for cohort and other common factors in treatment. During the 12 individual CaseM sessions the therapist and participant will identify problems in daily living that may be of concern, and consider community resources that might help in dealing with them (e.g., contacting a psychiatrist for depression, or finding a better place to live). The therapist's role is to explore the patient's concerns, help to identify goals and resources, provide verbal support, and troubleshoot difficulties that may arise in obtaining or following through with services. The support and attention to ancillary services has proven effective in reducing drinking in previous studies.
