Outcome Measures

Primary Outcomes (2)

  • GABA Pre and Post Progesterone Administration (Dorsal Anterior Cingulate Cortex [DACC])

    GABA concentrations (collected in the Dorsal Anterior Cingulate Cortex \[DACC\]) will be obtained using the non-invasive neuroimaging method of proton magnetic resonance spectroscopy (1H-MRS) both before and after placebo administration and smoking abstinence. In total subjects will undergo 6 1H-MRS scans. The 6 1H-MRS scans take place over a period of approximately 1-2 months. Each paradigm (placebo/progesterone) takes approximately one week, with an approximately two-week wash in between paradigms for men and an approximately 1-month wash in between paradigms for women. The subject will undergo a smoking session on Test Day #1 and Test Day #5, MRS scans are conducted on Test Day #2 (2 scans) and Test Day #5 (1 scan). Minimal data is available for the primary outcome due to substantial issues with the 7T scanner. All subsequent scans were conducted on a 3T scanner which does not have the capacity to collect data on GABA.

    Test Day #2 and Test Day #5 - 6 total scans over the period of 2-3 months.

  • GABA Pre and Post Progesterone Administration (Dorsolateral Pre-Frontal Cortex [DLPFC])

    GABA concentrations (collected in the Dorsolateral Pre-Frontal Cortex \[DLPFC\]) will be obtained using the non-invasive neuroimaging method of proton magnetic resonance spectroscopy (1H-MRS) both before and after placebo administration and smoking abstinence. In total subjects will undergo 6 1H-MRS scans. The 6 1H-MRS scans take place over a period of approximately 1-2 months. Each paradigm (placebo/progesterone) takes approximately one week, with an approximately two-week wash in between paradigms for men and an approximately 1-month wash in between paradigms for women. The subject will undergo a smoking session on Test Day #1 and Test Day #5, MRS scans are conducted on Test Day #2 (2 scans) and Test Day #5 (1 scan). Minimal data is available for the primary outcome due to substantial issues with the 7T scanner. All subsequent scans were conducted on a 3T scanner which does not have the capacity to collect data on GABA.

    Test Day #2 and Test Day #5 - 6 total scans over the period of 2-3 months.

Secondary Outcomes (31)

  • Symptoms During Nicotine Abstinence (NWSC)

    Day 1 (pre and post smoking session, day 2 (pre and post scan), day 3 (AM and PM), day 4 (AM and PM), day 5 (pre and post smoking session)

  • Brief Questionnaire on Smoking Urges (BQSU)

    Day 1 (pre and post smoking session, day 2 (pre and post scan), day 3 (AM and PM), day 4 (AM and PM), day 5 (pre and post smoking session)

  • Tiffany Questionnaire on Smoking Urges (TQSU)

    Day 1 (pre smoking session, day 3 (PM), day 4 (PM), day 5 (pre smoking session)

  • Profile of Mood States (POMS) Subscale: Tension-Anxiety

    Day 2 (pre and post scan), Day 5 (pre smoking session)

  • Profile of Mood States (POMS) Subscale: Depression-Dejection

    Day 2 (pre and post scan), Day 5 (pre smoking session)

  • +26 more secondary outcomes
