The Gender-Sex Hormone Interface With Craving & Stress-Related Changes in Smoking (SCOR-III)
The purpose of the overall parent study is to determine the impact of gender and hormones (estradiol, progesterone, testosterone and cortisol) on responses to stress and smoking cues presented in daily, "real-world" cue presentations compared to a final cue session in a lab. In addition, in the portion of the study that incorporates clinical trials elements and is reported here, the study will examine the impact of a single dose of oxytocin (chemical produced in the body) versus placebo (inactive substance) on reactivity to a stress procedure (Trier Social Stress Task) in smokers.
The overall parent study involves a cue presentation technology known as "CREMA" (Cue Reactivity Ecologic Momentary Assessment) which delivers four daily cue presentations to you on a handheld device during your everyday routine. Additionally, the study involves daily collection of saliva samples for hormonal testing. These daily procedures will provide information about the role of cues and hormones in daily life. The clinical trial portion of the study (reported here) consists of measures collected within the laboratory.

Detailed Description
Despite considerable advances in treatment development, cigarette smoking remains the leading cause of preventable death in the United States, and most smokers engaged in treatment are unsuccessful in quitting. The burden of illness is disproportionately borne by female smokers, who are less responsive to cessation interventions than males. The relationships between stress, craving, and smoking behavior are recognized as key factors underlying gender differences in nicotine dependence, but must be better understood and characterized to yield avenues for interventions addressing this critical health disparity.
In prior and ongoing SCOR studies, our research team has demonstrated gender and menstrual cycle/sex hormone influences on reactivity to laboratory-presented cues. Building from these laboratory findings, we propose taking two important next steps: (1) evaluating the experience of craving in the "real world" natural environment of female and male smokers, and (2) examining the impact of a safe and novel pharmacological intervention (oxytocin) on stress reactivity in female and male smokers.
If, as hypothesized, gender, sex hormones, and oxytocin administration influence the relationships between stress, craving, and smoking behavior, the findings could substantially address a key gender-related health disparity. Such knowledge could also inform the development of gender-specific interventions to enhance female smokers' response to cessation treatments. Therefore, the knowledge to be gained from the proposed study may yield significant public health benefits.

Measure Description |
Time Frame |
---|---|---|
Craving Response to Trier Social Stress Task
Time Frame: Immediately after the conclusion of the TSST
|
The TSST is the gold standard for evoking stress response in the laboratory. The participant must deliver a speech as though speaking to a group of hiring managers. The participant has 5 min to prepare, then three individuals unfamiliar to the participant (the audience) enter the room and are seated; the participant is instructed give the speech (without notes). The speech is delivered for 5 min, then the participant is instructed to serially subtract 13 from 1,022 as quickly and accurately as possible. The mental math recitation continues for 5 min, and at its conclusion, the spokesperson instructs the participant to stop and be seated, and the audience leaves the room. The total time for the TSST is 15 min. The Craving Questionnaire (Carter & Tiffany, 2001) is the sum of 4 items, each rated 1-5 on a Likert scale, with total score ranging 4-20, and higher scores indicating higher craving. |

The total time for the TSST is 15 min. The single stress item is derived from the CREMA Mood/Stress Assessment (Warthen & Tiffany, 2009), asking how stressed the participant felt at that time, on a 5-point Likert scale, ranging 1-5 with higher score indicating feeling more stressed |
