Smoking Behavior and Perceived Stress in Cigarette Smokers Undergoing Elective Surgery

Background: The forced abstinence from cigarettes accompanying surgery in smoke-free facilities may increase psychological stress by removing a coping mechanism and by nicotine withdrawal. The authors tested the hypothesis that abstinence from cigarette smoking contributes to psychological stress in the perioperative period. Methods: The authors assessed measures of nicotine withdrawal (Hughes-Hatsukami nicotine withdrawal scale) and perceived stress (including the Perceived Stress Scale) in 141 cigarette smokers scheduled to undergo elective surgery. To separate the effects of stress arising from tobacco abstinence from the effects of other perioperative stressors, such as pain, these measures were also obtained in 150 surgical patients who did not use tobacco. Assessments were performed at intervals beginning at the time of preoperative medical evaluation and ending 30 days postoperatively. Results: Perceived Stress Scale scores were significantly (P < 0.001) higher in smokers throughout the study period. There was little significant interaction between smoking status and time, indicating that changes in Perceived Stress Scale score during the perioperative period did not differ between smokers and nonsmokers. The same result was found if analysis was restricted to data collected before hospital discharge (and thus during assured abstinence). Similar results were found for the nicotine withdrawal scale, suggesting that smokers did not experience more withdrawal symptoms relative to nonsmokers. Conclusions: Although smokers report increased baseline stress, smoking status does not affect changes in perceived stress over the perioperative period. Nicotine withdrawal symptoms do not seem to be a clinically significant problem in the perioperative period for most smokers.

Effect of nicotine replacement therapy on stress and smoking behavior in surgical patients

Background:Many surgical patients are dependent on nicotine. Smoke-free policies in healthcare facilities mandate abstinence from smoking, which could contribute to psychological stress in the perioperative period. The authors tested the hypothesis that nicotine replacement therapy decreases psychological stress in cigarette smokers scheduled to undergo elective surgery and determined whether nicotine replacement therapy affects postoperative smoking behavior, even when not specifically prescribed to promote abstinence. Methods:In this double-blind, placebo-controlled trial, 121 smokers, of whom 116 received a study intervention, were randomly assigned to receive either active (nicotine-containing) or placebo patches, beginning on the morning of surgery and continuing for up to 30 days after discharge from the hospital. Outcomes included the Perceived Stress Score, the Nicotine Withdrawal Score, and subject self-report of smoking behavior. Results:The Perceived Stress Score and the Nicotine Withdrawal Score did not change significantly from baseline over the immediate perioperative period and did not differ between active or placebo patch groups (all P > 0.19). The percentage of placebo versus active patch subjects reporting 7-day abstinence at 30 days postoperatively (30% vs. 39%; P = 0.29) did not differ significantly between groups. At 30 days postoperatively, subjects in both groups significantly reduced their cigarettes smoked per day from baseline, but those receiving active patches reported a greater decrease (a mean decrease of 11 ± 11 vs. 15 ± 7 cigarettes/day in placebo and active groups; P = 0.045). Conclusion:Routine nicotine replacement therapy is not indicated in smokers undergoing surgery for the purposes of managing nicotine withdrawal and stress but can modify some aspects of postoperative smoking behavior.

Utilization of medical services and quality of life among low-income patients with generalized anxiety disorder attending primary care clinics.

Objective: Anxiety disorders appear to influence morbidity and medical utilization. However, little is known about the relationship between Generalized Anxiety Disorder, quality of life, and medical utilization, especially among low-income patients. The goals of this investigation were to 1) determine if low-income patients with GAD utilize medical services more than patients with other Axis I diagnoses, or no psychopathology, and 2) compare the health-related quality of life of these three groups. Method: Participants were randomly recruited from public primary care clinics and administered intake assessments of demographics, stress, and health-related self-report questionnaires. At the end of the first year a structured psychiatric interview was administered (N = 431). Over the second year, patients (n = 360) were administered a health-related quality of life measure every three months for four assessments. Medical charts were abstracted to collect information about chronic illnesses and visits to outpatient clinics and the emergency department during the two years. Results: Patients were predominantly middle-aged, low-income, uninsured African-American females. In this low-income sample, patients with GAD utilized the emergency department more and reported poorer quality of life than patients with other Axis I disorders and patients without any psychopathology. Conclusion: Low-income patients with GAD utilize the emergency department more and report poorer quality of life than patients with other Axis I disorders and patients without any psychopathology. Programs to identify and treat patients with GAD may yield improvements in quality of life, as well as reduce emergency department utilization.

Personality correlates related to tobacco abstinence following treatment.

Objective: The five-factor model of personality was used to describe the correlates of smoking abstinence. Methods: Following treatment in the Mayo Clinic Nicotine Dependence Center, the six month abstinence status was determined by self-report. Sixteen months to 2.4 years following the initial treatment evaluation, and 10 months to 1.9 years after the abstinence status was determined, 475 patients were mailed a Neuroticism, Extraversion, Openness, Five-Factor Inventory questionnaire. Ninety-nine abstinent and 151 smoking patients returned a completed questionnaire. Results: Multivariate analysis showed that low scores on neuroticism and openness were associated with tobacco abstinence. In addition, high scores on neuroticism and low scores on agreeableness and conscientiousness were associated with predictors of poor outcome including greater number of cigarettes smoked per day, initiation of smoking prior to age 18, and a Fagerström Test for Nicotine Dependence score of ≥ 6. Conclusions: Personality characteristics as predictors of smoking abstinence following treatment warrant further investigation in prospective clinical trails. Treatment matching using personality profiling as a guide may be a valuable tool for improving abstinence rates following treatment for nicotine dependence.

Efficacy of a Brief Image-Based Multiple-Behavior Intervention for College Students

BackgroundEpidemiologic data indicate most adolescents and adults experience multiple, simultaneous risk behaviors.PurposeThe purpose of this study is to examine the efficacy of a brief image-based multiple-behavior intervention (MBI) for college students.MethodsA total of 303 college students were randomly assigned to: (1) a brief MBI or (2) a standard care control, with a 3-month postintervention follow-up.ResultsOmnibus treatment by time multivariate analysis of variance interactions were significant for three of six behavior groupings, with improvements for college students receiving the brief MBI on alcohol consumption behaviors, F(6, 261) = 2.73, p = 0.01, marijuana-use behaviors, F(4, 278) = 3.18, p = 0.01, and health-related quality of life, F(5, 277) = 2.80, p = 0.02, but not cigarette use, exercise, and nutrition behaviors. Participants receiving the brief MBI also got more sleep, F(1, 281) = 9.49, p = 0.00, than those in the standard care control.ConclusionsA brief image-based multiple-behavior intervention may be useful in influencing a number of critical health habits and health-related quality-of-life indicators of college students.

The impact of minor stressful life events and social support on cravings: A study of inpatients receiving treatment for substance dependence

This study examined the incidence of cravings and minor stress events, whether stress predicted cravings, and whether social support predicted cravings or moderated the relation between stress and cravings. Participants included 39 inpatients being treated for substance dependence. Minor stress was assessed with the Daily Stress Inventory, social support was measured using the Interpersonal Support Evaluation List, and cravings were measured using the Daily Urge Record Sheet. Compared to normative data, participants reported a similar number of minor stressors and rated the impact of these events as somewhat, but not significantly, more stressful. A total of 64.10% of the sample did not experience cravings. A logistic regression revealed that number of minor stressors (b = 0.59, p < .05) and perceived impact of stress (b = 0.49, p < .05) predicted cravings. Social support moderated the association between incidence of stressors and cravings (b = -0.10, p < .05). These findings suggest that minor stress may contribute to cravings, and supports the social support buffering hypothesis. Implications for theory and future research about the role of minor stress and cravings in substance abuse are discussed.

Are effects from a brief multiple behavior intervention for college students sustained over time

OBJECTIVE This study examined whether 3-month outcomes of a brief image-based multiple behavior intervention on health habits and health-related quality of life of college students were sustained at 12-month follow-up without further intervention. METHODS A randomized control trial was conducted with 303 undergraduates attending a public university in southeastern US. Participants were randomized to receive either a brief intervention or usual care control, with baseline, 3-month, and 12-month data collected during fall of 2007. RESULTS A significant omnibus MANOVA interaction effect was found for health-related quality of life, p=0.01, with univariate interaction effects showing fewer days of poor spiritual health, social health, and restricted recent activity, ps<0.05, for those receiving the brief intervention. Significant group by time interaction effects were found for driving after drinking, p=0.04, and moderate exercise, p=0.04, in favor of the brief intervention. Effect sizes typically increased over time and were small except for moderate size effects for social health-related quality of life. CONCLUSION This study found that 3-month outcomes from a brief image-based multiple behavior intervention for college students were partially sustained at 12-month follow-up.

A prospective study of the impact of stress on quality of life: An investigation of low-income individuals with hypertension

The role that major and minor life events play in the quality of life in low-income hypertensives was examined. Participants were randomly recruited from 2 primary care clinics at a public medical center. The study utilized a prospective design. Participants were determined to have hypertension and were being treated with antihypertensive medication prior to and throughout the duration of the study. Participants were administered the Life Experiences Survey and the Weekly Stress Inventory repeatedly during Year 1 to assess major and minor stress, respectively. Participants were repeatedly administered the RAND 36-Item Health Survey during Year 2 to assess quality of life. Usable data were obtained from 183 patients. Analyses revealed that major and minor stress were significant predictors of all measured domains of quality of life, even after age and number of chronic illnesses were statistically controlled. Minor stress contributed uniquely to the prediction of each dimension of quality of life even when age, number of chronic illnesses, and major life events were accounted for. Findings suggest that stress has a significant, persistent impact on the quality of life of low-income patients with established hypertension. These findings extend prior research that has examined the impact of medications on quality of life and suggest that stress needs to be accounted for as well.

Expressive Writing as a Smoking Cessation Treatment Adjunct for Young Adult Smokers

This investigation evaluated the efficacy of expressive writing as a treatment adjunct to a brief office smoking cessation intervention plus nicotine patch therapy in young adults. Participants aged 18-24 years were randomized to a brief office intervention (n=99) or to an expressive writing plus brief office intervention (n=97). Both conditions received four individual visits plus 6 weeks of nicotine patch therapy, which began on the quit date following the week 2 visit. Participants in the expressive writing plus brief intervention condition wrote for 2 consecutive days before and 3 consecutive days after the quit date. The brief office intervention group completed a control writing assignment. At end of treatment (week 8), biochemically confirmed 7-day point-prevalence abstinence for the expressive writing plus brief office intervention condition was significantly greater than for the brief office condition (33% vs. 20%, p=.043, OR=2.0, 95% CI=1.0-3.7, from a logistic regression adjusting for gender). At 24 and 52 weeks, abstinence rates were similar for the brief office intervention versus expressive writing plus brief office intervention (12% vs. 11% at 24 weeks; 11% vs. 11% at 52 weeks). The results suggest that expressive writing has promise as a smoking cessation treatment adjunct for young adults. Lengthier interventions or the use of boosters should be tested to extend treatment effects. However, participants reported a low level of enthusiasm for the expressive writing, which may be a barrier to implementing it over a longer time frame. Therefore, other modes of delivering expressive writing to young adult cigarette smokers should be explored.

Evaluation of the association of prostate cancer‐specific anxiety with sexual function, depression and cancer aggressiveness in men 1 year following surgical treatment for localized prostate cancer

Cancer‐specific anxiety (CSA) can affect treatment decisions and is common in men following surgery for prostate cancer (PCa). We hypothesized that CSA is also associated with factors affecting quality of life. Herein, we examine the association of CSA with psychosocial factors and PCa aggressiveness in a cohort of men 1 year after prostatectomy for localized PCa.
