简要总结

The objective of this study is to evaluate whether Osmotic-Release Methylphenidate (OROS MPH), relative to placebo, increases the effectiveness of standard smoking treatment (i.e., nicotine patch and individual smoking cessation counseling) in obtaining prolonged abstinence for smokers with Attention Deficit Hyperactivity Disorder (ADHD).

详细描述

The primary objective of this study is to evaluate whether OROS MPH (Concerta), relative to placebo, increases the effectiveness of standard smoking treatment (i.e., nicotine patch and individual smoking cessation counseling) in obtaining prolonged abstinence for smokers with ADHD. The study will involve an estimated 252 participants, recruited from approximately 6 sites.

结局指标

主要结局

Prolonged Abstinence

时间窗: Weeks 7-10

The smoking quit date was considered the first day of the O-MPH/P-Stnd Smoking Tx phase, which lasted for 6 weeks or more precisely 42 days (i.e., approximately weeks 5-10). The grace period was the first two weeks (i.e., days 1-14) with the remaining four weeks (days 15-42) comprising the period in which the participant must not meet criteria for treatment failure in order to be scored as obtaining prolonged abstinence. Self-report of cigarette use was assessed using a time-line follow-back (TLFB) assessment using carbon monoxide (CO)levels to correct self-reported smoking days. "Smoking days" were determined by starting with self-reported smoking and non-smoking days and using CO levels measured at weekly visits to modify the self-reports.

次要结局

  • Diagnostic and Statistical Manual-IV(DSM-IV) ADHD Rating Scale(Baseline and Study weeks 1,4,7,9,11)
  • Point-prevalence Abstinence(Week 11)
