RCT of a Motivational Decision Support System for Smokers with Severe Mental Illness
Principal Investigator
Study Number
D14095
Summary
In this study we will definitively test the decision support system in a randomized controlled trial (RCT) among smokers with severe mental illness (SMI) psychotic disorders. The Specific Aims of the study are: To determine whether use of the web-based decision support system leads to higher rates of initiation of smoking cessation treatment than use of a computerized educational pamphlet. We will also assess effectiveness on secondary outcomes, including smoking behavior, urges and outcome expectancies; level of dependence; intentions to quit and to use cessation treatment; and abstinence. To assess whether cognitive ability moderates initiation of smoking cessation treatment. Since cognitive impairment impedes use of standard web-based interventions by this group, and cognitive impairments likely supersede other potential moderators (education and socioeconomic status), this aim will be key to determining the success of our intervention and will guide further revisions if they are needed. To explore the effects of the decision support system and baseline cognitive ability on abstinence over 6 months We will examine the impact of the DSS on 7-day point prevalence tobacco abstinence at 6 months, and cumulative days of tobacco abstinence over 6 months. We will determine whether baseline cognition (scale scores) is associated with 7-day point prevalence tobacco abstinence at 6 months, and cumulative days of tobacco abstinence over 6 months.
