Negative Affect, Emotional Acceptance, and Smoking Cessation

Timothy P. Carmody; Cassandra Vieten; John A. Astin

Abstract This article describes recent theoretical developments and empirical findings regarding the role of negative affect (NA) and emotion regulation in nicotine dependence and smoking cessation. It begins with a review of affect-based models of addiction that address conditioning, affect motivational, and neurobiological mechanisms and then describes the role of NA and emotion regulation in the initiation and maintenance of cigarette smoking. Next, the role of emotion regulation, coping skill deficits, depression, and anxiety sensitivity in explaining the relationship between NA and smoking relapse are discussed. We then review recent models of affect regulation, including emotional intelligence, reappraisal and suppression, and emotional acceptance, and describe implications for substance abuse and smoking cessation interventions. Finally, we point out the need for further investigations of the moderating role of individual differences in response to NA in the maintenance of nicotine dependence, and controlled randomized trials testing the efficacy of acceptance-based interventions in facilitating smoking cessation and relapse prevention.

Development of an Acceptance-Based Coping Intervention for Alcohol Dependence Relapse Prevention

Cassandra Vieten; John A. Astin; Raymond Buscemi; Gantt P. Galloway

Both psychological and neurobiological findings lend support to the long-standing clinical observation that negative affect is involved in the development and maintenance of alcohol dependence, and difficulty coping with negative affect is a common precipitant of relapse after treatment. Although many current approaches to relapse prevention emphasize change-based strategies for managing negative cognitions and affect, acceptance-based strategies for preventing relapse to alcohol use are intended to provide methods for coping with distress that are fundamentally different from, though in theory complementary to, approaches that emphasize control and change. This paper describes the development of Acceptance-Based Coping for Relapse Prevention (ABCRP), a new intervention for alcohol-dependent individuals who are within 6 months of having quit drinking. Results of preliminary testing indicate that the intervention is feasible with this population; and a small uncontrolled pilot study (N = 23) showed significant (P < .01) improvements in self-reported negative affect, emotional reactivity, perceived stress, positive affect, psychological well-being, and mindfulness level, as well as a trend (P = .06) toward reduction in craving severity between pre- and postintervention assessments. The authors conclude that this acceptance-based intervention seems feasible and holds promise for improving affect and reducing relapse in alcohol-dependent individuals, warranting further research.

Introduction Recruiting participants for research studies can be challenging. Many studies fall short of their target or must prolong recruitment to reach it. We examined recruitment and retention strategies and report lessons learned in a behavioral intervention developmental trial to encourage healthy pregnancy weight gain and stress reduction in low-income overweight pregnant women. Methods In the San Francisco Bay area from February 2010 through March 2011, we used direct and indirect strategies to recruit English-speaking overweight and obese pregnant women who were aged 18 to 45, were in the early stages of pregnancy, and who had an annual household income less than 500% of the federal poverty guidelines. Eligible women who consented participated in focus groups or an 8-week behavioral intervention. We identified successful recruiting strategies and sites and calculated the percentage of women who were enrolled and retained. Results Of 127 women screened for focus group participation, 69 were eligible and enrolled. A total of 57 women participated in 9 focus groups and 3 women completed individual interviews for a completion rate of 87%. During recruitment for the intervention, we made contact with 204 women; 135 were screened, 33% were eligible, and 69.1% of eligible women enrolled. At 1 month postpartum, 82.6% of eligible women completed an assessment. Recruiting at hospital-based prenatal clinics was the highest-yielding strategy. Conclusion The narrow window of eligibility for enrolling early stage pregnant women in a group intervention presents obstacles. In-person recruitment was the most successful strategy; establishing close relationships with providers, clinic staff, social service providers, and study participants was essential to successful recruitment and retention.

We examined gender differences in age of onset, clinical course, and heritability of alcohol dependence in 2,524 adults participating in the University of California San Francisco (UCSF) family study of alcoholism. Men were significantly more likely than women to have initiated regular drinking during adolescence. Onset of regular drinking was not found to be heritable but was found to be significantly associated with a shorter time to onset of alcohol dependence. A high degree of similarity in the sequence of alcohol-related life events was found between men and women, however, men experienced alcohol dependence symptoms at a younger age and women had a more rapid clinical course. Women were found to have a higher heritability estimate for alcohol dependence (h(2)= .46) than men (h(2)= .32). These findings suggest that environmental factors influencing the initiation of regular drinking rather than genetic factors associated with dependence may in part underlie some of the gender differences seen in the prevalence of alcohol dependence in this population.

Cannabis is the most widely used illicit drug in the United States. There is ample evidence that cannabis use has a heritable component, yet the genes underlying cannabis use disorders are yet to be completely identified. This studys aims were to map susceptibility loci for cannabis use and dependence and two narrower cannabis‐related phenotypes of “craving” and “withdrawal” using a family study design. Participants were 2,524 adults participating in the University of California San Francisco (UCSF) Family Alcoholism Study. DSM‐IV diagnoses of cannabis dependence, as well as indices of cannabis craving and withdrawal, were obtained using a modified version of the Semi‐Structured Assessment for the Genetics of Alcoholism (SSAGA). Genotypes were determined for a panel of 791 microsatellite polymorphisms. Multipoint variance component LOD scores were obtained using SOLAR. Genome‐wide significance for linkage (LOD > 3.0) was not found for the DSM‐IV cannabis dependence diagnosis; however, linkage analyses of cannabis “craving” and the cannabis withdrawal symptom of “nervous, tense, restless, or irritable” revealed five sites with LOD scores over 3.0 on chromosomes 1, 3, 6, 7, and 9. These results identify new regions of the genome associated with cannabis use phenotypes as well as corroborate the importance of several chromosome regions highlighted in previous linkage analyses for other substance dependence phenotypes.

Ample data suggest that alcohol dependence represents a heritable condition, and several research groups have performed linkage analysis to identify genomic regions influencing this disorder. In the present study, a genome-wide linkage scan for alcohol dependence was conducted in a community sample of 565 probands and 1080 first-degree relatives recruited through the UCSF Family Alcoholism Study. The Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA) was used to derive DSM-IV alcohol dependence diagnoses. Although no loci achieved genome-wide significance (i.e., LOD score > 3.0), several linkage peaks of interest (i.e., LOD score > 1.0) were identified. When the strict DSM-IV alcohol dependence diagnosis requiring the temporal clustering of symptoms served as the phenotype, linkage peaks were identified on chromosomes 1p36.31-p36.22, 2q37.3, 8q24.3, and 18p11.21-p11.2. When the temporal clustering of symptoms was not required, linkage peaks were again identified on chromosomes 1p36.31-p36.22 and 8q24.3 as well as novel loci on chromosomes 1p22.3, 2p24.3-p24.1, 9p24.1-p23, and 22q12.3-q13.1. Follow-up analyses were conducted by performing linkage analysis for the 12 alcohol dependence symptoms assessed by the SSAGA across the support intervals for the observed linkage peaks. These analyses demonstrated that different collections of symptoms often assessing distinct aspects of alcohol dependence (e.g., uncontrollable drinking and withdrawal vs. tolerance and drinking despite health problems) contributed to each linkage peak and often yielded LOD scores exceeding that reported for the alcohol dependence diagnosis. Such findings provide insight into how specific genomic regions may influence distinct aspects of alcohol dependence.

Coming All the Way Home: Integrative Community Care for Those Who Serve

Joseph Bobrow; Emily T. Cook; Carrie Knowles; Cassandra Vieten

This project describes the programming and evaluation of Coming Home Project (CHP) retreats that address the mental, emotional, spiritual, and relationship challenges experienced by those affected by military service and deployments. Three types of retreats held for veterans, service members and their families, as well as professional service providers, were evaluated. Original program-evaluation measures were administered to elicit feedback from participants and facilitators to optimize the intervention, and to evaluate whether the experimental and learning objectives of retreat components were achieved. Data analyses reveal statistically significant reductions in stress and isolation, as well as improvements in relaxation and hope, for all retreat participants. Implications for the success of this type of innovative, resilience-based, community programming are discussed. Future directions are suggested for further research, replicability of these services in other locations, and the incorporation of CHP retreats into existing government programs and services.

Objective Epidemiological and clinical studies suggest that the rates of antisocial behavior, depression, and impulsive substance use are increased among individuals diagnosed with alcohol dependence relative to those who are not. Thus, the present study conducted genome-wide linkage scans of antisocial behavior, depression, and impulsive substance use in the University of California at San Francisco Family Alcoholism Study. Methods Antisocial behavior, depressive symptoms, and impulsive substance use were assessed using three scales from the Minnesota Multiphasic Personality Inventory – 2nd ed.: the Antisocial Practices content scale, the Depression content scale, and the revised MacAndrew Alcoholism scale. Linkage analyses were carried out using a variance components approach. Results Suggestive evidence of linkage to three genomic regions independent of alcohol and cannabis dependence diagnostic status was observed: the Antisocial Practices content scale showed evidence of linkage to chromosome 13 at 11 cM, the MacAndrew Alcoholism scale showed evidence of linkage to chromosome 15 at 47 cM, and all three scales showed evidence of linkage to chromosome 17 at 57–58 cM. Conclusion Each of these regions has shown previous evidence of linkage and association to substance dependence as well as other psychiatric disorders such as mood and anxiety disorders, attention-deficit hyperactivity disorder, and schizophrenia, thus suggesting potentially broad relations between these regions and psychopathology.

BACKGROUND Nicotine dependence has been shown to represent a heritable condition, and several research groups have performed linkage analysis to identify genomic regions influencing this disorder though only a limited number of the findings have been replicated. METHOD In the present study, a genome-wide linkage scan for nicotine dependence was conducted in a community sample of 950 probands and 1204 relatives recruited through the University of California, San Francisco (UCSF) Family Alcoholism Study. A modified version of the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA) with additional questions that probe nicotine use was used to derive DSM-IV nicotine dependence diagnoses. RESULTS A locus on chromosome 2q31.1 at 184 centiMorgans nearest to marker D2S2188 yielded a logarithm (base 10) of odds (LOD) score of 3.54 (point-wise empirical p=0.000012). Additional peaks of interest were identified on chromosomes 2q13, 4p15.33-31, 11q25 and 12p11.23-21. Follow-up analyses were conducted examining the contributions of individual nicotine dependence symptoms to the chromosome 2q31.1 linkage peak as well as examining the relationship of this chromosomal region to alcohol dependence. CONCLUSIONS The present report suggests that chromosome 2q31.1 confers risk to the development of nicotine dependence and that this region influences a broad range of nicotine dependence symptoms rather than a specific facet of the disorder. Further, the results show that this region is not linked to alcohol dependence in this population, and thus may influence nicotine dependence specifically.

Heritability of MMPI-2 Scales in the UCSF Family Alcoholism Study

Ian R. Gizer; Kimberley L. Seaton-Smith; Cindy L. Ehlers; Cassandra Vieten; Kirk C. Wilhelmsen

ABSTRACT The current study evaluated the heritability of personality traits and psychopathology symptoms assessed by the Minnesota Multiphasic Personality Inventory 2nd Edition (MMPI-2) in a family-based sample selected for alcohol dependence. Participants included 950 probands and 1,204 first-degree relatives recruited for the University of California at San Francisco (UCSF) Family Alcoholism Study. Heritability estimates for MMPI-2 scales ranged from .25 to .49. When alcohol dependence was used as a covariate, heritability estimates remained significant but generally declined. However, when the MMPI-2 scales were used as covariates to estimate the heritability of alcohol dependence, the scales measuring antisocial behavior, depressive symptoms, and addictive behavior led to moderate increases in the heritability of alcohol dependence. This suggests that the scales may explain some of the non-genetic variance in the alcohol dependence diagnosis in this population when used as covariates, and thus may serve to produce a more homogeneous and heritable alcohol-dependence phenotype.
