Abstract
In this study, we explored the temporal stability of the Personality Assessment Inventory (PAI), which has not been comprehensively reexamined since it was first published. Our three specific aims were to determine the utility of PAI indicators of basic protocol validity (inconsistent responses [ICN] and highly unusual/unlikely responses [INF]) in identifying suspect responding; calculate the stability coefficients for each PAI scale and subscale across 3-, 6-, and 9-week spans; and explore whether profile stability across four measurements could be prospectively predicted. We administered the PAI to a sample of undergraduates (N = 579) at four separate timepoints. ICN and INF effectively identified likely attriters and inconsistent responders. All PAI full scales and subscales evidenced good test-retest reliability, with some small exceptions. Finally, all PAI clinical scales were correlated with profile instability although many of these correlations were no longer significant when controlling for mean clinical elevation of the profile. We interpreted these results as evidence for the utility of PAI validity scales, the temporal reliability of the PAI, and the role of psychopathology in response variability over time. We also discussed some preliminary evidence that this variability can be prospectively predicted, suggesting that it in part reflects substantive changes rather than random error variance.

Abstract
Human epidemiological studies have identified links between nicotine intake and stress disorders, including anxiety, depression and PTSD. Here we review the clinical evidence for activation and desensitization of nicotinic acetylcholine receptors (nAChRs) relevant to affective disorders. We go on to describe clinical and preclinical pharmacological studies suggesting that nAChR function may be involved in the etiology of anxiety and depressive disorders, may be relevant targets for medication development, and may contribute to the antidepressant efficacy of non-nicotinic therapeutics. We then review what is known about nAChR function in a subset of limbic system areas (amygdala, hippocampus and prefrontal cortex), and how this contributes to stress-relevant behaviors in preclinical models that may be relevant to human affective disorders. Taken together, the preclinical and clinical literature point to a clear role for ACh signaling through nAChRs in regulation of behavioral responses to stress. Disruption of nAChR homeostasis is likely to contribute to the psychopathology observed in anxiety and depressive disorders. Targeting specific nAChRs may therefore be a strategy for medication development to treat these disorders or to augment the efficacy of current therapeutics.

Abstract
BACKGROUND High negative affect and low positive affect are key depression-related states that may be greater following acute tobacco abstinence. This study aimed to test associations between depression symptom levels and acute tobacco abstinence with negative affect and positive affect. METHODS Following a baseline session, participants attended two counterbalanced laboratory sessions (non-abstinent, abstinent) and completed measures of positive and negative affect at rest (i.e., when not completing a task) and during a film clip task. RESULTS Individuals with elevated depression symptoms had higher negative affect and lower positive affect at rest and during the film clip task compared to individuals with low depression symptoms. There was no interaction of depression symptom levels and abstinence on negative and positive affect at rest. There was an interaction of depression symptom level and abstinence on negative and positive affect during the film clip task. Individuals with elevated depression showed significant differences in positive and negative affect between the abstinent and non-abstinent session, but no significant abstinence effects were noted in individuals with low depression symptoms. LIMITATIONS The study included a non-treatment seeking sample and experimentally induced acute cigarette abstinence. We excluded for the use of smoking cessation medications that are also used to treat depression, classified depression levels using dichotomized CES-D scores, and used self-report measures of affect. CONCLUSIONS Results of this study suggest individuals with elevated depression symptoms who smoke experience elevated negative affect and lower positive affect and cigarette abstinence may uniquely alter affective reactivity in individuals with elevated depression symptoms.

Psychological distress and smoking behaviors of Chinese college students: mediating effects of the dimensions of learning burnout. BMC Psychol 2022; 10:125.

Abstract
Objectives Smokers or never smokers exposed to environmental tobacco use are usually associated with various diseases and cancers. In order to better help college students prevent the tobacco use and thus lower the incidence of avoidable diseases, this study explored the predictive power of different variables including demographic and psychological variables in relation to smoking behaviors. Methods Maslach Burnout Inventory-Student Survey and Kessler Psychological Distress Scale (K10) were used in this study. Results There were 1449 college students participating in the study with 1340 pieces of valid data left, the effective ratio was 92.48%. The valid data included 37.1% male and 62.9% female aged 18.83 on average with 1.55 standard deviation. The multivariate logistic regression indicated that college students who were male (versus female, OR = 9.55), majoring in medicine and sports (versus nursing, ORmedicine = 2.19, ORsports = 2.81), born in the non-singleton family (versus singleton family, OR = 0.63) with higher family income (versus lower family income, OR = 0.45), surrounded with smoking friends (versus without smoking friends, OR = 0.18), were more vulnerable to smoke. In addition, combined with the theory of planned behavior, the dimensions of learning burnout had full mediation effects between psychological distress and smoking behavior. Conclusions Psychological distress can only indirectly affect smoking behavior via learning efficacy, cynicism and emotional exhaustion. Adjustments from different dimensions of learning burnout such as avoiding cynicism about learning, enhancing learning efficacy and emotion exhaustion will help college students better prevent the tobacco use.

Abstract
BACKGROUND A sizeable literature highlighted that negative affectivity and craving are both known to be implicated in relapses. OBJECTIVES The present study synthetized the existing litterature to determine strength of the interaction between negative affectivity and craving for substance-related disorders including illicit drugs, alcohol and tobacco. METHODS We conducted a systematic review in accordance with PRISMA guidelines followed by a meta-analysis. Online computer databases PubMed, PsycINFO and Web of Science were searched systematically and thoroughly. Jamovi 1.8.1 Current version was used to conduct meta-analysis. RESULTS Thirty studies were included in the review, and 14 of these, including 2257 subjects, were used for meta-analysis. The raw correlation ranged from 0.17 to 0.58, which indicated weak to moderate association between negative affects and craving. In total, approximately 90% of the selection revealed a positive correlation between negative affects and craving. Alcohol and tobacco use disorders have received the most attention. Additionally, negative affectivity was often defined as a transient state rather than a stable personality trait. CONCLUSIONS In both of our meta-analyses and in the narratively reported studies, we found that negative affectivity is an important component related to craving, but individual differences in craving reactivity existed.

Abstract
Prior findings indicate that trait anhedonia enhances the likelihood of becoming a tobacco smoker, and preliminary evidence suggests that smoking abstinence leads to anhedonic states in some individuals and situations, and nicotine administration reduces anhedonic states. Nevertheless, many vital questions exist concerning relationships between anhedonia and nicotine dependence, including situational and individual difference factors that may moderate the strength of these associations. This chapter provides a critical review of the literature assessing relationships of anhedonia to nicotine dependence and the effects of acute nicotine through the lenses of the Research Domain Criteria's (RDoC) Positive Valence Systems (NIMH, RDoC changes to the matrix (CMAT) workgroup update: proposed positive valence domain revisions. A report by the national advisory mental health council workgroup on changes to the research domain criteria matrix, 2018) and the Situation x Trait Affective Response (STAR) model of nicotine's effects and nicotine dependence (Gilbert, Smoking individual differences, psychopathology, and emotion. Taylor and Francis, Washington, DC, 1995; Gilbert, Hum Psychopharmacol Clin Exp 12:S89-S102, 1997). The effects of nicotine and nicotine withdrawal on subjective, behavioral, and brain indices vary across the three RDoC Positive Valences Systems (Reward Responsiveness, Reward Learning, and Reward Valuation) in a manner that supports the research and potential clinical utility of using RDoC criteria and the STAR model to guide research and clinical innovation. We provide a revision of the STAR model that incorporates the three RDoC Positive Valence Systems with evidence that nicotine's effects on hedonic and affective processes vary as a function of the dominance/salience of (1) situational hedonic and affective cues and task/active coping cues, and (2) state executive functioning level/capacity and state reward sensitivity such that these effects of nicotine are maximal during states of suboptimal cognitive functioning and reward sensitivity, combined with low situational stimulus salience and low task-related cues/demands.

Abstract
We report that regions-of-interest (ROIs) associated with idiosyncratic individual behavior can be identified from functional magnetic resonance imaging (fMRI) data using statistical approaches that explicitly model individual variability in neuronal activations, such as mixed-effects multilevel analysis (MEMA). We also show that the relationship between neuronal activation in fMRI and behavioral data can be modeled using canonical correlation analysis (CCA). A real-world dataset for the neuronal response to nicotine use was acquired using a custom-made MRI-compatible apparatus for the smoking of electronic cigarettes (e-cigarettes). Nineteen participants smoked e-cigarettes in an MRI scanner using the apparatus with two experimental conditions: e-cigarettes with nicotine (ECIG) and sham e-cigarettes without nicotine (SCIG) and subjective ratings were collected. The right insula was identified in the ECIG condition from the χ2 -test of the MEMA but not from the t-test, and the corresponding activations were significantly associated with the similarity scores (r = -.52, p = .041, confidence interval [CI] = [-0.78, -0.17]) and the urge-to-smoke scores (r = .73, p <.001, CI = [0.52, 0.88]). From the contrast between the two conditions (i.e., ECIG > SCIG), the right orbitofrontal cortex was identified from the χ2 -tests, and the corresponding neuronal activations showed a statistically meaningful association with similarity (r = -.58, p = .01, CI = [-0.84, -0.17]) and the urge to smoke (r = .34, p = .15, CI = [0.09, 0.56]). The validity of our analysis pipeline (i.e., MEMA followed by CCA) was further evaluated using the fMRI and behavioral data acquired from the working memory and gambling tasks available from the Human Connectome Project.

Abstract
INTRODUCTION The high smoking prevalence amongst individuals with psychiatric disorders constitutes a major public health disparity. Negative reinforcement models of addiction posit that severe tobacco withdrawal symptoms, related to the affective vulnerabilities of these smokers, may thwart their quitting smoking successfully. However, relatively few studies have prospectively examined the effects of nicotine deprivation on withdrawal symptoms in these groups. METHODS This study compared the level of withdrawal symptoms both before and after nicotine deprivation in those diagnosed with posttraumatic stress disorder (PTSD) or major depressive disorder (MDD) and in those without psychiatric diagnoses. Participants were US veterans who smoked (≥10 cigarettes/day) and met diagnostic criteria for PTSD (n = 38), MDD (n = 43), or no psychiatric diagnosis ("controls" n = 44). Participants attended study visits before and during 48-hour nicotine deprivation to report tobacco withdrawal symptoms. Analyses evaluated withdrawal symptom levels (baseline and during nicotine deprivation) and the change in symptoms related to nicotine deprivation and compared (1) participants with a psychiatric diagnosis versus controls, and (2) participants with PTSD versus MDD. RESULTS Contrary to hypotheses, nicotine deprivation produced greater increases in most withdrawal symptoms amongst controls than in those with psychiatric diagnoses. Compared with controls, those with PTSD or MDD reported elevated symptom levels both before and after tobacco deprivation for most withdrawal symptoms. CONCLUSIONS These findings suggest that chronically high levels of distress and craving, rather than acute increases in withdrawal symptoms because of nicotine deprivation, may account for the quitting difficulties of those with comorbid conditions such as PTSD and MDD. IMPLICATIONS Severe tobacco withdrawal may account for the higher quitting difficulties of smokers with either posttraumatic stress disorder (PTSD) or major depressive disorder (MDD). Paradoxically, this study showed that individuals with no psychiatric diagnosis had greater increases in tobacco withdrawal severity because of nicotine deprivation than did those with either PTSD or MDD. Those with either PTSD or MDD showed high stable levels of withdrawal symptom severity both before and during two days of abstinence, suggesting that their quitting difficulties may be related to their chronically high levels of distress rather than nicotine deprivation per se.

Abstract
INTRODUCTION Rates of light smoking have increased in recent years and are associated with adverse health outcomes. Reducing light smoking is a challenge because it is unclear why some but not others, progress to heavier smoking. Nicotine has profound effects on brain reward systems and individual differences in nicotine's reward-enhancing effects may drive variability in smoking trajectories. Therefore, we examined whether a genetic risk factor and personality traits known to moderate reward processing, also moderate the reward-enhancing effects of nicotine. METHODS Light smokers (n = 116) performed a Probabilistic Reward Task to assess reward responsiveness after receiving nicotine or placebo (order counterbalanced). Individuals were classified as nicotine dependence 'risk' allele carriers (rs16969968 A-allele carriers) or non-carriers (non-A-allele carriers), and self-reported negative affective traits were also measured. RESULTS Across the sample, reward responsiveness was greater following nicotine compared to placebo (p = 0.045). For Caucasian A-allele carriers but not non-A-allele carriers, nicotine enhanced reward responsiveness compared to placebo for those who received placebo first (p = 0.010). Furthermore, for A-allele carriers but not non-A-allele carriers who received nicotine first, the enhanced reward responsiveness in the nicotine condition carried over to the placebo condition (p < 0.001). Depressive traits also moderated the reward-enhancing effects of nicotine (p = 0.010) and were associated with blunted reward responsiveness following placebo but enhanced reward responsiveness following nicotine. CONCLUSION These findings suggest that individual differences in a genetic risk factor and depressive traits alter nicotine's effect on reward responsiveness in light smokers and may be important factors underpinning variability in smoking trajectories in this growing population. IMPLICATIONS Individuals carrying genetic risk factors associated with nicotine dependence(rs16969968 A-allele carriers) and those with higher levels of depressive personality traits, showmore pronounced increases in reward learning following acute nicotine exposure. These findingssuggest that genetic and personality factors may drive individual differences in smoking trajectoriesin young light smokers by altering the degree to which nicotine enhances reward processing.

Abstract
BACKGROUND There is a common perception that smoking generally helps people to manage stress, and may be a form of 'self-medication' in people with mental health conditions. However, there are biologically plausible reasons why smoking may worsen mental health through neuroadaptations arising from chronic smoking, leading to frequent nicotine withdrawal symptoms (e.g. anxiety, depression, irritability), in which case smoking cessation may help to improve rather than worsen mental health. OBJECTIVES To examine the association between tobacco smoking cessation and change in mental health. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group's Specialised Register, Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PsycINFO, and the trial registries clinicaltrials.gov and the International Clinical Trials Registry Platform, from 14 April 2012 to 07 January 2020. These were updated searches of a previously-conducted non-Cochrane review where searches were conducted from database inception to 13 April 2012. SELECTION CRITERIA: We included controlled before-after studies, including randomised controlled trials (RCTs) analysed by smoking status at follow-up, and longitudinal cohort studies. In order to be eligible for inclusion studies had to recruit adults who smoked tobacco, and assess whether they quit or continued smoking during the study. They also had to measure a mental health outcome at baseline and at least six weeks later. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methods for screening and data extraction. Our primary outcomes were change in depression symptoms, anxiety symptoms or mixed anxiety and depression symptoms between baseline and follow-up. Secondary outcomes included change in symptoms of stress, psychological quality of life, positive affect, and social impact or social quality of life, as well as new incidence of depression, anxiety, or mixed anxiety and depression disorders. We assessed the risk of bias for the primary outcomes using a modified ROBINS-I tool. For change in mental health outcomes, we calculated the pooled standardised mean difference (SMD) and 95% confidence interval (95% CI) for the difference in change in mental health from baseline to follow-up between those who had quit smoking and those who had continued to smoke. For the incidence of psychological disorders, we calculated odds ratios (ORs) and 95% CIs. For all meta-analyses we used a generic inverse variance random-effects model and quantified statistical heterogeneity using I2. We conducted subgroup analyses to investigate any differences in associations between sub-populations, i.e. unselected people with mental illness, people with physical chronic diseases. We assessed the certainty of evidence for our primary outcomes (depression, anxiety, and mixed depression and anxiety) and our secondary social impact outcome using the eight GRADE considerations relevant to non-randomised studies (risk of bias, inconsistency, imprecision, indirectness, publication bias, magnitude of the effect, the influence of all plausible residual confounding, the presence of a dose-response gradient). MAIN RESULTS We included 102 studies representing over 169,500 participants. Sixty-two of these were identified in the updated search for this review and 40 were included in the original version of the review. Sixty-three studies provided data on change in mental health, 10 were included in meta-analyses of incidence of mental health disorders, and 31 were synthesised narratively. For all primary outcomes, smoking cessation was associated with an improvement in mental health symptoms compared with continuing to smoke: anxiety symptoms (SMD -0.28, 95% CI -0.43 to -0.13; 15 studies, 3141 participants; I2 = 69%; low-certainty evidence); depression symptoms: (SMD -0.30, 95% CI -0.39 to -0.21; 34 studies, 7156 participants; I2 = 69%' very low-certainty evidence); mixed anxiety and depression symptoms (SMD -0.31, 95% CI -0.40 to -0.22; 8 studies, 2829 participants; I2 = 0%; moderate certainty evidence). These findings were robust to preplanned sensitivity analyses, and subgroup analysis generally did not produce evidence of differences in the effect size among subpopulations or based on methodological characteristics. All studies were deemed to be at serious risk of bias due to possible time-varying confounding, and three studies measuring depression symptoms were judged to be at critical risk of bias overall. There was also some evidence of funnel plot asymmetry. For these reasons, we rated our certainty in the estimates for anxiety as low, for depression as very low, and for mixed anxiety and depression as moderate. For the secondary outcomes, smoking cessation was associated with an improvement in symptoms of stress (SMD -0.19, 95% CI -0.34 to -0.04; 4 studies, 1792 participants; I2 = 50%), positive affect (SMD 0.22, 95% CI 0.11 to 0.33; 13 studies, 4880 participants; I2 = 75%), and psychological quality of life (SMD 0.11, 95% CI 0.06 to 0.16; 19 studies, 18,034 participants; I2 = 42%). There was also evidence that smoking cessation was not associated with a reduction in social quality of life, with the confidence interval incorporating the possibility of a small improvement (SMD 0.03, 95% CI 0.00 to 0.06; 9 studies, 14,673 participants; I2 = 0%). The incidence of new mixed anxiety and depression was lower in people who stopped smoking compared with those who continued (OR 0.76, 95% CI 0.66 to 0.86; 3 studies, 8685 participants; I2 = 57%), as was the incidence of anxiety disorder (OR 0.61, 95% CI 0.34 to 1.12; 2 studies, 2293 participants; I2 = 46%). We deemed it inappropriate to present a pooled estimate for the incidence of new cases of clinical depression, as there was high statistical heterogeneity (I2 = 87%). AUTHORS' CONCLUSIONS Taken together, these data provide evidence that mental health does not worsen as a result of quitting smoking, and very low- to moderate-certainty evidence that smoking cessation is associated with small to moderate improvements in mental health. These improvements are seen in both unselected samples and in subpopulations, including people diagnosed with mental health conditions. Additional studies that use more advanced methods to overcome time-varying confounding would strengthen the evidence in this area.

Abstract
INTRODUCTION Most descriptions of tobacco withdrawal have not changed in >30 years despite new research. This meta-analysis tested whether abstinence leads to decreased positive affect (PA) because abstinence-induced symptom changes are a core feature of the tobacco withdrawal syndrome. In addition, we examined whether reduced PA was due to withdrawal (ie, temporary decrease in a "U-shaped" curve) or offset (ie, return to baseline) effect. METHODS Our main inclusion criterion was a prospective within-participant test of change in PA during abstinence conditions among people who smoke cigarettes daily who were not using a cessation medication. Our search of PubMed, PsycINFO, and personal libraries yielded a total of 32 tests with 2054 participants. RESULTS There was a medium effect size indicating an overall decrease in PA following abstinence from cigarettes (Cohen's d = -0.40, 95% CI = -0.30 to -0.49). There was large heterogeneity (I2 = 70.7%). Most (79%) of the 24 trials that conducted significance tests reported that reduction in PA was significant. Seven tests were adequately designed to detect a withdrawal versus offset effect. Over half (57%) displayed a U-shaped curve for abstinence-induced change in PA indicative of a withdrawal symptom rather than offset effect. CONCLUSIONS Abstinence from cigarettes is associated with a decrease in PA. Whether low PA should be added to withdrawal measures and diagnostic criteria requires replication of the time-course of change in PA and tests of whether abstinence-induced changes in PA and negative affect occur independently. IMPLICATIONS Though there was substantial heterogeneity among trials, our findings suggest that (1) abstinence from cigarettes decreases positive affect and (2) this decrease may represent a withdrawal effect (vs. an offset effect). However, it is unclear whether abstinence-induced losses in positive affect are independent from increased negative affect.

Nicotine patch for cannabis withdrawal symptom relief: a randomized controlled trial. Psychopharmacology (Berl) 2020; 237:1507-1519. [PMID: 32034447 DOI: 10.1007/s00213-020-05476-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Accepted: 01/30/2020] [Indexed: 10/24/2022]
Abstract
RATIONALE Given that tetrahydrocannabinol (THC) and nicotine have similar effects on negative affect (NA), we hypothesized that a 7-mg nicotine patch (NP) would reduce NA-related cannabis (CAN) withdrawal symptoms in cannabis-dependent (CD) individuals who were not nicotine dependent. OBJECTIVE We sought to determine whether NP reduces NA across 15 days of CAN abstinence in two groups: non-tobacco smokers (NTS) and light tobacco smokers (LTS). METHODS CD participants (N = 127; aged 18-35) who used CAN at least 5 times/week for the past 12 + months were randomized to (1) NP or (2) a placebo patch (PP) and received $300 for sustained biochemically verified CAN abstinence. Of those randomly assigned, 52 of 63 NP, and 56 of 64 PP maintained biochemically verified CAN abstinence and 51 NP and 50 PP participants complied with all aspects of the study. Affect and other withdrawal symptoms were measured every 48 h across 15 days of CAN abstinence. RESULTS After controlling for age, tobacco use, baseline THC concentration, and baseline measurements of the dependent variable, NP reduced NA symptoms across the 15-day treatment relative to PP. Differences in NA and CAN withdrawal symptoms were not moderated by tobacco user status. CONCLUSIONS The findings provide the first evidence that NP may be able to attenuate NA-related withdrawal symptoms in individuals with cannabis use disorder who are not heavy users of tobacco or nicotine.

Abstract
Accurate knowledge of negative affect (NA)-related smoking abstinence symptoms (SAS) severity and duration and their moderation by pharmacotherapy and NA-related personality traits is critical for efficacious treatments given that elevated state and trait NA are predictors of relapse. However, SAS severity, duration, and moderation are not well characterized. To date, the longest randomized controlled trial (RCT) of NA-related SAS using randomized delayed-quit smoking controls only examined symptoms across 45 days, despite clinical evidence that SAS may last longer. The present RCT assessed SAS across 67 days in dependent smokers (N = 95) who were randomized either to quit or to delay quitting for the course of the trial. The quit group was further randomized to receive either nicotine replacement therapy (NRT), bupropion (BUP), or placebo. Abstinence-related increases in anger-irritability, depressive, anxiety, and general NA symptoms did not resolve relative to the delayed quit group (DQG) levels across the 67 days in any of the 3 quit groups, though craving fell to below DQG and prequit levels. While NRT attenuated Day 3 SAS relative to BUP and placebo, BUP and NRT generally did not reduce SAS. High scores on trait measures of NA/neuroticism predicted greater increases in and duration of NA-related SAS, potentially indicating that smoking abstinence unmasks affective symptoms. Positive affect was not impacted by abstinence or treatment. The results support the views that (a) prequit baseline values are not a valid index of NA SAS recovery, and (b) on average, NA-related SAS take longer than 67 days to resolve.

Abstract
BACKGROUND Financial incentives, monetary or vouchers, are widely used in an attempt to precipitate, reinforce and sustain behaviour change, including smoking cessation. They have been used in workplaces, in clinics and hospitals, and within community programmes. OBJECTIVES To determine the long-term effect of incentives and contingency management programmes for smoking cessation. SEARCH METHODS For this update, we searched the Cochrane Tobacco Addiction Group Specialised Register, clinicaltrials.gov, and the International Clinical Trials Registry Platform (ICTRP). The most recent searches were conducted in July 2018. SELECTION CRITERIA We considered only randomised controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to smoking cessation incentive schemes or control conditions. We included studies in a mixed-population setting (e.g. community, work-, clinic- or institution-based), and also studies in pregnant smokers. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. The primary outcome measure in the mixed-population studies was abstinence from smoking at longest follow-up (at least six months from the start of the intervention). In the trials of pregnant women we used abstinence measured at the longest follow-up, and at least to the end of the pregnancy. Where available, we pooled outcome data using a Mantel-Haenzel random-effects model, with results reported as risk ratios (RRs) and 95% confidence intervals (CIs), using adjusted estimates for cluster-randomised trials. We analysed studies carried out in mixed populations separately from those carried out in pregnant populations. MAIN RESULTS Thirty-three mixed-population studies met our inclusion criteria, covering more than 21,600 participants; 16 of these are new to this version of the review. Studies were set in varying locations, including community settings, clinics or health centres, workplaces, and outpatient drug clinics. We judged eight studies to be at low risk of bias, and 10 to be at high risk of bias, with the rest at unclear risk. Twenty-four of the trials were run in the USA, two in Thailand and one in the Phillipines. The rest were European. Incentives offered included cash payments or vouchers for goods and groceries, offered directly or collected and redeemable online. The pooled RR for quitting with incentives at longest follow-up (six months or more) compared with controls was 1.49 (95% CI 1.28 to 1.73; 31 RCTs, adjusted N = 20,097; I2 = 33%). Results were not sensitive to the exclusion of six studies where an incentive for cessation was offered at long-term follow up (result excluding those studies: RR 1.40, 95% CI 1.16 to 1.69; 25 RCTs; adjusted N = 17,058; I2 = 36%), suggesting the impact of incentives continues for at least some time after incentives cease.Although not always clearly reported, the total financial amount of incentives varied considerably between trials, from zero (self-deposits), to a range of between USD 45 and USD 1185. There was no clear direction of effect between trials offering low or high total value of incentives, nor those encouraging redeemable self-deposits.We included 10 studies of 2571 pregnant women. We judged two studies to be at low risk of bias, one at high risk of bias, and seven at unclear risk. When pooled, the nine trials with usable data (eight conducted in the USA and one in the UK), delivered an RR at longest follow-up (up to 24 weeks post-partum) of 2.38 (95% CI 1.54 to 3.69; N = 2273; I2 = 41%), in favour of incentives. AUTHORS' CONCLUSIONS Overall there is high-certainty evidence that incentives improve smoking cessation rates at long-term follow-up in mixed population studies. The effectiveness of incentives appears to be sustained even when the last follow-up occurs after the withdrawal of incentives. There is also moderate-certainty evidence, limited by some concerns about risks of bias, that incentive schemes conducted among pregnant smokers improve smoking cessation rates, both at the end of pregnancy and post-partum. Current and future research might explore more precisely differences between trials offering low or high cash incentives and self-incentives (deposits), within a variety of smoking populations.

Abstract
AIMS Personality characteristics are linked to nicotine dependence (ND). It remains unclear whether these factors differ across African-American (AA) and European-American (EA) male and female smokers. This study was aimed to determine the relationship between personality traits and smoking status, as well as the degree of ND, in AA and EA male and female samples. METHODS A total of 5,040 participants (AA: N = 3,737, female = 54.31%; EA: N = 1,313, female = 64.51%) were included in this study, with 2,474 smokers and 2,566 non-smokers. The measures used in this study included five dimensions of personality by the NEO-personality inventory-revised (neuroticism, extraversion, agreeableness, openness to experience, and conscientiousness), Fagerström test for ND, and drive subscale of the ND Syndrome Scale (NDSS). RESULTS In the AA sample, neuroticism was significantly associated with a higher risk of smoking [odds ratio (OR) = 1.057; 95% confidence interval (CI) 1.032, 1.083; p < 0.0001], and conscientiousness was significantly associated with decreased risk of smoking (OR = 0.936; 95% CI 0.912, 0.961; p < 0.0001). In the EA sample, higher neuroticism was associated with increased risk of being a current smoker (OR = 1.058; 95% CI 1.013, 1.104; p = 0.0105). Furthermore, we found that a lower level of neuroticism and higher level of conscientiousness were associated with the severity of ND in both the AA and EA samples and a broader range of personality factors were involved in predicting the severity of ND in the AA samples. However, no differential association was detected between male and female smokers of both AA and EA samples. CONCLUSION There exist differential relationships between personality traits and the severity of ND in the AA and EA samples.

Abstract
OBJECTIVE To develop and validate parallel short forms for the assessment of general anxiety in cardiovascular rehabilitation patients, that facilitate repeated measurement over time without contamination from residual practice effect variance. DESIGN Development of the parallel short forms using Rasch analysis. Validation study. SETTING Cardiac rehabilitation centres in Germany. SUBJECTS Cardiovascular rehabilitation patients. INTERVENTIONS Not applicable. MAIN MEASURES Parallel short forms PaSA-cardio, Hospital Anxiety and Depression Scale, Short Form Health Survey SF-12 and Structured Clinical Interview for DSM-IV Axis I Disorders. RESULTS Each version of the parallel short forms (PaSA-cardio-I and PaSA-cardio-II) comprises ten items. The two forms fitted to the Rasch model with a non-significant item-trait interaction (PaSA-cardio-I: chi-square = 39.49, degrees of freedom = 30, probability = 0.12; PaSA-cardio-II: chi-square = 26.56, degrees of freedom = 30, probability = 0.65). Person-separation reliability was 0.75/0.76. Unidimensionality could be verified. Correlation between the two models was 0.94 and 0.95, and correlations with the underlying item bank were 0.95 and 0.93. Validity could be confirmed. The area under the curve was between 0.88 and 0.97 for PaSA-cardio-I and between 0.92 and 0.95 for PaSA-cardio-II. CONCLUSIONS Assessment of general anxiety in cardiovascular rehabilitation patients with the PaSA-cardio was valid, economical and accurate. The two forms of the PaSA-cardio are equivalent and allow retest without contamination from residual practice effect variance.

Abstract
INTRODUCTION Persistent tobacco use among racial and ethnic minority populations in the United States is a critical public health concern. Yet, potential sources of racial/ethnic disparities in tobacco use remain unclear. The present study examined racial/ethnic differences in tobacco withdrawal-a clinically-relevant underpinning of tobacco use that has received sparse attention in the disparities literature-utilizing a controlled laboratory design. METHODS Daily smokers (non-Hispanic African American [n = 178], non-Hispanic white [n = 118], and Hispanic [n = 28]) attended two counterbalanced sessions (non-abstinent vs. 16-hour abstinent). At both sessions, self-report measures of urge, nicotine withdrawal, and affect were administered and performance on an objective behavioral task that assessed motivation to reinstate smoking was recorded. Abstinence-induced changes (abstinent scores vs. non-abstinent scores) were analyzed as a function of race/ethnicity. RESULTS Non-Hispanic African American smokers reported greater abstinence-induced declines in several positive affect states in comparison to other racial/ethnic groups. Relative to Hispanic smokers, non-Hispanic African American and non-Hispanic white smokers displayed larger abstinence-provoked increases in urges to smoke. No racial/ethnic differences were detected for a composite measure of nicotine withdrawal symptomatology, negative affect states, and motivation to reinstate smoking behavior. CONCLUSIONS These results suggest qualitative differences in the expression of some components of tobacco withdrawal across three racial/ethnic groups. This research helps shed light on bio-behavioral sources of tobacco-related health disparities, informs the application of smoking cessation interventions across racial/ethnic groups, and may ultimately aid the overall effort towards reducing the public health burden of tobacco addiction in minority populations. IMPLICATIONS The current study provides some initial evidence that there may be qualitative differences in the types of tobacco withdrawal symptoms experienced among non-Hispanic African American, Hispanic, and non-Hispanic white smokers. Extending this line of inquiry may elucidate mechanisms involved in tobacco-related health disparities and ultimately aid in reducing the public health burden of smoking in racial/ethnic minority populations.

Abstract
BACKGROUND Material or financial incentives are widely used in an attempt to precipitate or reinforce behaviour change, including smoking cessation. They operate in workplaces, in clinics and hospitals, and to a lesser extent within community programmes. In this third update of our review we now include trials conducted in pregnant women, to reflect the increasing activity and resources now targeting this high-risk group of smokers. OBJECTIVES To determine whether incentives and contingency management programmes lead to higher long-term quit rates. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register, with additional searches of MEDLINE, EMBASE, CINAHL and PsycINFO. The most recent searches were in December 2014, although we also include two trials published in 2015. SELECTION CRITERIA We considered randomised controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to experimental or control conditions. We also considered controlled studies with baseline and post-intervention measures. We include studies in a mixed-population setting (e.g. community-, work-, institution-based), and also, for this update, trials in pregnant smokers. DATA COLLECTION AND ANALYSIS One author (KC) extracted data and a second (JH-B) checked them. We contacted study authors for additional data where necessary. The main outcome measure in the mixed-population studies was abstinence from smoking at longest follow-up, and at least six months from the start of the intervention. In the trials of pregnant smokers abstinence was measured at the longest follow-up, and at least to the end of the pregnancy. MAIN RESULTS Twenty-one mixed-population studies met our inclusion criteria, covering more than 8400 participants. Ten studies were set in clinics or health centres, one in Thai villages served by community health workers, two in academic institutions, and the rest in worksites. All but six of the trials were run in the USA. The incentives included lottery tickets or prize draws, cash payments, vouchers for goods and groceries, and in six trials the recovery of money deposited by those taking part. The odds ratio (OR) for quitting with incentives at longest follow-up (six months or more) compared with controls was 1.42 (95% confidence interval (CI) 1.19 to 1.69; 17 trials, [20 comparisons], 7715 participants). Only three studies demonstrated significantly higher quit rates for the incentives group than for the control group at or beyond the six-month assessment: One five-arm USA trial compared rewards- and deposit-based interventions at individual and group level, with incentives available up to USD 800 per quitter, and demonstrated a quit rate in the rewards groups of 8.1% at 12 months, compared with 4.7% in the deposits groups. A direct comparison between the rewards-based and the deposit-based groups found a benefit for the rewards arms, with an OR at 12 months of 1.76 (95% CI 1.22 to 2.53; 2070 participants). Although more people in this trial accepted the rewards programmes than the deposit programmes, the proportion of quitters in each group favoured the deposit-refund programme. Another USA study rewarded both participation and quitting up to USD 750, and achieved sustained quit rates of 9.4% in the incentives group compared with 3.6% for the controls. A deposit-refund trial in Thailand also achieved significantly higher quit rates in the intervention group (44.2%) compared with the control group (18.8%), but uptake was relatively low, at 10.5%. In the remaining trials, there was no clear evidence that participants who committed their own money to the programme did better than those who did not, or that contingent rewards enhanced success rates over fixed payment schedules. We rated the overall quality of the older studies as low, but with later trials (post-2000) more likely to meet current standards of methodology and reporting.Eight of nine trials with usable data in pregnant smokers (seven conducted in the USA and one in the UK) delivered an adjusted OR at longest follow-up (up to 24 weeks post-partum) of 3.60 (95% CI 2.39 to 5.43; 1295 participants, moderate-quality studies) in favour of incentives. Three of the trials demonstrated a clear benefit for contingent rewards; one delivered monthly vouchers to confirmed quitters and to their designated 'significant other supporter', achieving a quit rate in the intervention group of 21.4% at two months post-partum, compared with 5.9% among the controls. Another trial offered a scaled programme of rewards for the percentage of smoking reduction achieved over the course of the 12-week intervention, and achieved an intervention quit rate of 31% at six weeks post-partum, compared with no quitters in the control group. The largest (UK-based) trial provided intervention quitters with up to GBP 400-worth of vouchers, and achieved a quit rate of 15.4% at longest follow-up, compared to the control quit rate of 4%. Four trials confirmed that payments made to reward a successful quit attempt (i.e. contingent), compared to fixed payments for attending the antenatal appointment (non-contingent), resulted in higher quit rates. Front-loading of rewards to counteract early withdrawal symptoms made little difference to quit rates. AUTHORS' CONCLUSIONS Incentives appear to boost cessation rates while they are in place. The two trials recruiting from work sites that achieved sustained success rates beyond the reward schedule concentrated their resources into substantial cash payments for abstinence. Such an approach may only be feasible where independently-funded smoking cessation programmes are already available, and within a relatively affluent and educated population. Deposit-refund trials can suffer from relatively low rates of uptake, but those who do sign up and contribute their own money may achieve higher quit rates than reward-only participants. Incentive schemes conducted among pregnant smokers improved the cessation rates, both at the end-of-pregnancy and post-partum assessments. Current and future research might continue to explore the scale, loading and longevity of possible cash or voucher reward schedules, within a variety of smoking populations.

Abstract
The co-morbidity between smoking and mood disorders is striking. Preclinical and clinical studies of nicotinic effects on mood, anxiety, aggression, and related behaviors, such as irritability and agitation, suggest that smokers may use the nicotine in tobacco products as an attempt to self-medicate symptoms of affective disorders. The role of nicotinic acetylcholine receptors (nAChRs) in circuits regulating mood and anxiety is beginning to be elucidated in animal models, but the mechanisms underlying the effects of nicotine on aggression-related behavioral states (ARBS) are still not understood. Clinical trials of nicotine or nicotinic medications for neurological and psychiatric disorders have often found effects of nicotinic medications on ARBS, but few trials have studied these outcomes systematically. Similarly, the increase in ARBS resulting from smoking cessation can be resolved by nicotinic agents, but the effects of nicotinic medications on these types of mental states and behaviors in non-smokers are less well understood. Here we review the literature on the role of nAChRs in regulating mood and anxiety, and subsequently on the closely related construct of ARBS. We suggest avenues for future study to identify how nAChRs and nicotinic agents may play a role in these clinically important areas. This article is part of the Special Issue entitled 'The Nicotinic Acetylcholine Receptor: From Molecular Biology to Cognition'.

The nicotine (NIC) withdrawal syndrome is considered to be a major cause of the high relapse rate among individuals undergoing smoking cessation. The aim of the present study was to evaluate a possible role of GABAB receptors in NIC withdrawal, by comparing GABAB1 knockout mice and their wild-type littermates. We analysed the time course of the global withdrawal score, the anxiety-like effects, monoamine concentrations, the brain-derived neurotrophic factor (BDNF) expression, the corticosterone plasmatic levels and [(3)H]epibatidine binding sites during NIC withdrawal precipitated by mecamylamine, a nicotinic receptor antagonist (MEC). In NIC withdrawn wild-type mice, we observed a global withdrawal score, an anxiety-like effect in the elevated plus maze, a decrease of the striatal dopamine and 3,4-dihydroxyphenylacetic acid concentrations, an increase of corticosterone plasma levels, a reduction of BDNF expression in several brain areas and an increase of [(3)H]epibatidine binding sites in specific brain regions. Interestingly, the effects found in NIC withdrawn wild-type mice were absent in GABAB1 knockout mice, suggesting that GABAB1 subunit of the GABAB receptor is involved in the regulation of the behavioural and biochemical alterations induced by NIC withdrawal in mice. These results reveal an interaction between the GABAB receptors and the neurochemical systems through which NIC exerts its long-term effects.

Nicotine and non-nicotine smoking factors differentially modulate craving, withdrawal and cerebral blood flow as measured with arterial spin labeling. Neuropsychopharmacology 2014; 39:2750-9.

Abstract
Smoking cessation results in withdrawal symptoms such as craving and negative mood that may contribute to lapse and relapse. Little is known regarding whether these symptoms are associated with the nicotine or non-nicotine components of cigarette smoke. Using arterial spin labeling, we measured resting-state cerebral blood flow (CBF) in 29 adult smokers across four conditions: (1) nicotine patch+denicotinized cigarette smoking, (2) nicotine patch+abstinence from smoking, (3) placebo patch+denicotinized cigarette smoking, and (4) placebo patch+abstinence from smoking. We found that changes in self-reported craving positively correlated with changes in CBF from the denicotinized cigarette smoking conditions to the abstinent conditions. These correlations were found in several regions throughout the brain. Self-reported craving also increased from the nicotine to the placebo conditions, but had a minimal relationship with changes in CBF. The results of this study suggest that the non-nicotine components of cigarette smoke significantly impact withdrawal symptoms and associated brain areas, independently of the effects of nicotine. As such, the effects of non-nicotine factors are important to consider in the design and development of smoking cessation interventions and tobacco regulation.

Abstract
OBJECTIVE The goal of this study was to assess the efficacy and tolerability of lis-dexamfetamine dimesylate (LDX) as an adjunct to nicotine replacement therapy in adult smokers with ADHD who were undergoing a quit attempt. METHODS Thirty-two regular adult smokers with ADHD were randomized to receive LDX (n = 17) or placebo (n = 15) in addition to nicotine patch concurrent with a quit attempt. RESULTS There were no differences between smokers assigned to LDX versus placebo in any smoking outcomes. Participants treated with LDX demonstrated significant reductions in self-reported and clinician-rated ADHD symptoms. LDX was well tolerated in smokers attempting to quit. DISCUSSION In general, LDX does not facilitate smoking cessation in adults with ADHD more than does placebo, though both groups significantly reduced smoking. LDX demonstrated efficacy for reducing ADHD symptoms in adult smokers engaging in a quit attempt.

Abstract
OBJECTIVES The neurophysiology, risk factors, and screening tools associated with alcohol withdrawal syndrome in the ICU are reviewed. Alcohol withdrawal syndrome assessment and its treatment options are discussed. Description of nicotine withdrawal and related publications specific to the critically ill are also reviewed. A brief comment as to sedative and opiate withdrawal follows. DATA AND SUMMARY The role of currently published alcohol withdrawal syndrome pharmacologic strategies (benzodiazepines, ethanol, clomethiazole, antipsychotics, barbiturates, propofol, and dexmedetomidine) is detailed. Studies on nicotine withdrawal management in the ICU focus mainly on the safety (mortality) of nicotine replacement therapy. Study characteristics and methodological limitations are presented. CONCLUSION We recommend a pharmacologic regimen titrated to withdrawal symptoms in ICU patients with alcohol withdrawal syndrome. Benzodiazepines are a reasonable option; phenobarbital appears to confer some advantages in combination with benzodiazepines. Propofol and dexmedetomidine have not been rigorously tested in comparative studies of drug withdrawal treatment; their use as additional or alternative strategies for managing withdrawal syndromes in ICU patients should therefore be individualized to each patient. Insufficient data preclude recommendations as to nicotine replacement therapy and management of iatrogenic drug withdrawal in ICU patients.

Abstract
PURPOSE Daily assessments can provide insight into the temporal characteristics of fatigue. They can demonstrate consistency or reveal variability, as when fatigue changes with the underlying medical condition, improves with therapy, or worsens as a medication side effect. We adapted a fatigue measure from the Patient-Reported Outcomes Measurement Information System (PROMIS(®)) for daily assessment and examined its psychometric properties in a month-long prospective study. METHODS Three groups of 100 participants each were drawn from two fatigue-related clinical disorders [osteoarthritis (OA) and premenstrual syndrome/premenstrual dysphoric disorder (PMS/PMDD)], and a general population sample (GP). They completed brief daily web-based fatigue measures at home on 28 consecutive evenings. RESULTS Compliance was high for all samples, based on the percent of participants who remained in the study (98 % for GP and OA, 95 % for PMS/PMDD). The new scale performed consistently across the groups, sensitively measuring fatigue with high reliability (>0.90) especially in the average to high fatigue level range. Supporting known-groups validity, fatigue scores were elevated in the clinical groups as compared to the GP. The scale was sensitive to change, with the PMS/PMDD sample showing a linear increase in fatigue prior to menses onset, and a sharp drop off afterward. CONCLUSIONS The scale was psychometrically sound across diverse clinical and general population samples, though less reliable when assessing lower levels of fatigue.

Abstract
INTRODUCTION Hostility--a personality trait reflective of cynical attitudes and a general mistrust of others--is associated with smoking status and relapse risk. Yet, the mechanisms linking hostility and smoking are not entirely clear. In this lab study, we tested a socioaffective model that purports that high-hostility individuals smoke to cope with maladaptive social mood states (i.e., anger and low friendliness), which become expressed and exacerbated during acute tobacco withdrawal. METHODS Following a baseline visit at which trait hostility was assessed, adult smokers (n = 153, ≥10 cig/day) attended two counterbalanced lab visits: a deprived session following 16 hr of deprivation, and a nondeprived session. At both lab visits, affect and withdrawal symptoms were assessed at a single time point. RESULTS Higher trait hostility predicted larger deprivation-induced increases in several forms of negative affect (anxiety, depression, confusion; βs ≥ .20, ps ≤ .01) and a composite tobacco withdrawal symptom index (β = .16, p = .04) but did not predict changes in positive emotions. These effects persisted after statistically controlling for gender, nicotine dependence, and depression. Other aspects of trait aggression (i.e., verbal aggression, physical aggression, anger) did not predict deprivation-induced changes in affect and withdrawal other than state anger. DISCUSSION High-hostility individuals appear to experience generalized exacerbations in several negative affective states during acute tobacco withdrawal. Increases in negative affect during tobacco withdrawal may motivate negative reinforcement-mediated smoking and could underlie tobacco addiction in high-hostility smokers.

Abstract
Smoking abstinence disrupts affective and cognitive processes. In this study, functional magnetic resonance imaging (fMRI) was used to investigate the effects of smoking abstinence on emotional information processing. Smokers (n = 17) and non-smokers (n = 18) underwent fMRI while performing an emotional distractor oddball task in which rare targets were presented following negative and neutral task-irrelevant distractors. Smokers completed two sessions: once following 24-hour abstinence and once while satiated. The abstinent versus satiated states were compared by evaluating responses to distractor images and to targets following each distractor valence within frontal executive and limbic brain regions. Regression analyses were done to investigate whether self-reported negative affect influences brain response to images and targets. Exploratory regression analyses examined relations between baseline depressive symptoms and smoking state on brain function. Smoking state affected response to target detection in the right inferior frontal gyrus (IFG). During satiety, activation was greater in response to targets following negative versus neutral distractors; following abstinence, the reverse was observed. Withdrawal-related negative affect was associated with right insula activation to negative images. Finally, depression symptoms were associated with abstinence-induced hypoactive response to negative emotional distractors and task-relevant targets following negative distractors in frontal brain regions. Neural processes related to novelty detection/attention in the right IFG may be disrupted by smoking abstinence and negative stimuli. Reactivity to emotional stimuli and the interfering effects on cognition are moderated by the magnitude of smoking state-dependent negative affect and baseline depressive symptoms.

Abstract
Negative affect is thought to be an important factor in the maintenance of cigarette smoking, and thus it is important to further develop objective measures of smoking-related emotional responses. Nonsmokers, non abstinent smokers, and abstinent smokers participated in a cue reactivity task where eyeblink startle amplitude and startle probe P300 (P3) suppression were measured during the presentation of emotional pictures.During unpleasant pictures, the amplitude of both measures was smaller in non abstinent smokers than in nonsmokers or abstinent smokers. P3 suppression, but not startle amplitude, was larger in abstinent smokers than in nonsmokers. Abstinence-induced increases in cigarette craving were associated with P3 suppression during tobacco-related pictures. Results suggest that tobacco abstinence increases emotional reactivity to unpleasant stimuli, which is consistent with negative reinforcement models of tobacco addiction.

Abstract
BACKGROUND Background Material or financial incentives may be used in an attempt to reinforce behaviour change, including smoking cessation. They have been widely used in workplace smoking cessation programmes, and to a lesser extent within community programmes. Public health initiatives in the UK are currently planning to deploy incentive schemes to change unhealthy behaviours. Quit and Win contests are the subject of a companion review. OBJECTIVES To determine whether competitions and incentives lead to higher long-term quit rates. We also set out to examine the relationship between incentives and participation rates. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group Specialized Register, with additional searches of MEDLINE, EMBASE, CINAHL and PsycINFO. Search terms included incentive*, competition*, contest*, reward*, prize*, contingent payment*, deposit contract*. The most recent searches were in November 2010. SELECTION CRITERIA We considered randomized controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to experimental or control conditions. We also considered controlled studies with baseline and post-intervention measures. DATA COLLECTION AND ANALYSIS Data were extracted by one author (KC) and checked by the second (RP). We contacted study authors for additional data where necessary. The main outcome measure was abstinence from smoking at least six months from the start of the intervention. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Where possible we performed meta-analysis using a generic inverse variance model, grouped by timed endpoints, but not pooled across the subgroups. MAIN RESULTS Nineteen studies met our inclusion criteria, covering >4500 participants. Only one study, the largest in our review and covering 878 smokers, demonstrated significantly higher quit rates for the incentives group than for the control group beyond the six-month assessment. This trial referred its participants to local smoking cessation services, and offered substantial cash payments (up to US$750) for prolonged abstinence. In the remaining trials, there was no clear evidence that participants who committed their own money to the programme did better than those who did not, or that contingent rewards enhanced success rates over fixed payment schedules. There is some evidence that recruitment rates can be improved by rewarding participation, which may be expected to deliver higher absolute numbers of successful quitters. Cost effectiveness analysis was not appropriate to this review, since the efficacy of most of the interventions was not demonstrated. AUTHORS' CONCLUSIONS With the exception of one recent trial, incentives and competitions have not been shown to enhance long-term cessation rates. Early success tended to dissipate when the rewards were no longer offered. Rewarding participation and compliance in contests and cessation programmes may have potential to deliver higher absolute numbers of quitters. The one trial that achieved sustained success rates beyond the reward schedule concentrated its resources into substantial cash payments for abstinence rather than into running its own smoking cessation programme. Such an approach may only be feasible where independently-funded smoking cessation programmes are already available. Future research might explore the scale and longevity of possible cash reward schedules, within a variety of smoking populations.

Abstract
We examined the variation and heritability of DSM-IV nicotine withdrawal (NW) in adult and adolescent male and female twin cigarette smokers (who reported smoking 100 or more cigarettes lifetime). Telephone diagnostic interviews were completed with 3,112 Australian adult male and female smokers (53% women; age: 24-36) and 702 Missouri adolescent male and female smokers (59% girls; age: 15-21). No gender or cohort differences emerged in rates of meeting criteria for NW (44%). Latent class analyses found that NW symptoms were best conceptualized as a severity continuum (three levels in adults and two levels in adolescents). Across all groups, increasing NW severity was associated with difficulty quitting, impairment following cessation, heavy smoking, depression, anxiety, conduct disorder and problems with alcohol use. NW was also associated with seeking smoking cessation treatment and with smoking persistence in adults. The latent class structure of NW was equally heritable across adult and adolescent smokers with additive genetic influences accounting for 49% of the variance and the remaining 51% of variance accounted for by unique environmental influences. Overall, findings suggest remarkable similarity in the pattern and heritability of NW across adult and adolescent smokers, and highlight the important role of NW in psychiatric comorbidity and the process of smoking cessation across both age groups.

Abstract
RATIONALE Previous studies have documented the existence of signs and symptoms of the acute tobacco abstinence syndrome; however, less attention has been paid to quantifying the magnitude of these effects. OBJECTIVE The present study quantified the relative magnitude of subjective, cognitive, and physiological manifestations of acute tobacco abstinence. METHOD Smokers (N=203, ≥ 15 cig/day) attended two counterbalanced laboratory sessions, one following 12-h of abstinence and the other following ad-lib smoking. At both sessions, they completed an extensive battery of self-report measures (withdrawal, affect, hunger, craving, subjective attentional bias towards smoking cues), physiological assessments (heart rate, blood pressure, brain EEG), and cognitive performance tasks (psychomotor processing, sustained attention, objective attentional bias). RESULTS Abstinence effects were largest for craving, subjective attentional bias, negative affect, overall withdrawal severity, concentration difficulty, hunger, and heart rate. Effects were moderate for positive affect and EEG power. Effects were small, but reliable, for psychomotor speed, sustained attention, and somatic symptoms. Effects on performance-based indices of attentional bias towards smoking-related cues were small and reliable for some indices but not others. Effects were small and inconsistent for blood pressure and EEG frequency. Variation in internal consistency accounted for 33% of the variation in abstinence effect sizes across measures. CONCLUSIONS There was a wide range of effect sizes both across and within domains, indicating that the acute tobacco abstinence syndrome is not a monotonic phenomenon. These findings may be indicative of the relative magnitudes of signs and symptoms that the average smoker may exhibit during acute abstinence.

Abstract
AIMS We have demonstrated previously that acute smoking abstinence is associated with lowered reward motivation and impaired response inhibition. This prospective study explores whether these impairments, along with withdrawal-related symptoms, recover over 3 months of sustained abstinence. DESIGN Participants completed a 12-hour abstinent baseline assessment and were then allocated randomly to quit unaided or continue smoking. All were re-tested after 7 days, 1 month and 3 months. Successful quitters' scores were compared with those of continuing smokers, who were tested after ad libitum smoking. SETTING Goldsmiths, University of London. PARTICIPANTS A total of 33 smokers who maintained abstinence to 3 months, and 31 continuing smokers. MEASUREMENTS Indices demonstrated previously in this cohort of smokers to be sensitive to the effect of nicotine versus acute abstinence: reward motivation [Snaith-Hamilton pleasure scale (SHAPS), Card Arranging Reward Responsivity Objective Test (CARROT), Stroop], tasks of response inhibition [anti-saccade task; Continuous Performance Task (CPT)], clinical indices of mood [Hospital Anxiety and Depression Scale (HADS)], withdrawal symptoms [Mood and Physical Symptoms Scale (MPSS)] and desire to smoke. FINDINGS SHAPS anhedonia and reward responsivity (CARROT) showed significant improvement and plateaued after a month of abstinence, not differing from the scores of continuing smokers tested in a satiated state. Mood, other withdrawal symptoms and desire to smoke all declined from acute abstinence to 1 month of cessation and were equivalent to, or lower than, the levels reported by continuing, satiated smokers. Neither group showed a change in CPT errors over time while continuing smokers, but not abstainers, showed improved accuracy on the anti-saccade task at 3 months. CONCLUSION Appetitive processes and related affective states appear to improve in smokers who remain nicotine-free for 3 months, whereas response inhibition does not. Although in need of replication, the results suggest tentatively that poor inhibitory control may constitute a long-term risk factor for relapse and could be a target for intervention.

Abstract
This study examined associations between three temperament dimensions measured by the Temperament and Character Inventory-125 [Cloninger, C.R. (1992). The Temperament and Character Inventory-125 (TCI-125; Version 1.)] and tobacco abstinence effects. Smokers (N=203, >/= 15 cigarettes/day) attended two laboratory sessions, one following 12 h of abstinence and the other following ad libitum smoking (order counterbalanced). Participants completed measures of withdrawal symptoms, cigarette urges, and affect. Smokers high in Novelty Seeking reported greater abstinence-induced increases in several nicotine withdrawal symptoms, negative affect, and cigarette craving. Smokers high in Harm Avoidance reported greater abstinence-induced increases in negative affect and urges to smoke to relieve distress. Reward Dependence was not associated with abstinence effects. Novelty Seeking and Harm Avoidance showed independent predictive associations with negative affect and urges, and their associations with abstinence effects persisted when controlling for FTND scores. Smokers with different temperaments display different patterns of acute tobacco withdrawal, and may benefit from treatments matched to their particular abstinence profile.

Abstract
Heavy drinking and associated consequences are widespread among U.S. college students. Recently, Read et al. (Read, J. P., Kahler, C. W., Strong, D., & Colder, C. R. (2006). Development and preliminary validation of the Young Adult Alcohol Consequences Questionnaire. Journal of Studies on Alcohol, 67, 169-178) developed the Young Adult Alcohol Consequences Questionnaire (YAACQ) to assess the broad range of consequences that may result from heavy drinking in the college milieu. In the present study, we sought to add to the psychometric validation of this measure by employing a prospective design to examine the test-retest reliability, concurrent validity, and predictive validity of the YAACQ. We also sought to examine the utility of the YAACQ administered early in the semester in the prediction of functional outcomes later in the semester, including the persistence of heavy drinking, and academic functioning. Ninety-two college students (48 females) completed a self-report assessment battery during the first weeks of the Fall semester, and approximately one week later. Additionally, 64 subjects (37 females) participated at an optional third time point at the end of the semester. Overall, the YAACQ demonstrated strong internal consistency, test-retest reliability, and concurrent and predictive validity. YAACQ scores also were predictive of both drinking frequency, and "binge" drinking frequency. YAACQ total scores at baseline were an early indicator of academic performance later in the semester, with greater number of total consequences experienced being negatively associated with end-of-semester grade point average. Specific YAACQ subscale scores (Impaired Control, Dependence Symptoms, Blackout Drinking) showed unique prediction of persistent drinking and academic outcomes.

Abstract
AIMS To examine the natural history of nicotine withdrawal and individual differences associated with withdrawal duration and severity. DESIGN AND SETTING Prospective study of withdrawal symptoms among smokers who quit for at least 24 hours. Participants used Ecological Momentary Assessment to monitor symptoms in their natural environment using an Electronic Diary (ED). PARTICIPANTS A total of 214 cigarette smokers (59% female, 92% Caucasian). INTERVENTION All participants received a clinic-based, behavioral, group cessation intervention. Severity and duration of withdrawal was not addressed explicitly in treatment. MEASUREMENTS Participants were 'beeped' by the ED approximately five times/day to complete affect assessments (negative affect, arousal, attention disturbance, restlessness), and daily assessments of sleep disturbance (at waking) and of cognitive performance (each evening) for a week prior to quitting and for up to 21 days after quitting. Withdrawal was considered resolved when withdrawal scores returned to baseline levels for at least 2 consecutive days. FINDINGS All symptoms returned to baseline levels within 10 days of quitting. All variables except arousal and sleep disturbance showed change over time. No robust predictors of individual differences in withdrawal responses emerged. CONCLUSIONS The time-course of withdrawal may be shorter than previously reported. The natural history of nicotine withdrawal may have implications for theories of withdrawal and smoking relapse and for smoking cessation treatment.

Abstract
RATIONALE Despite established links between nicotine dependence and depression, little research has examined the effects of nicotine on depression symptoms. OBJECTIVE This study evaluated the acute and chronic effects of transdermal nicotine in nonsmokers with baseline depression symptoms during a 4-week, double-blind, placebo-controlled trial. METHODS Nonsmokers with scores >or=10 on the Center for Epidemiological Studies Depression scale (CES-D) were recruited from the community. Mood and cognitive performance were measured at baseline (day 0) and at 1, 8, 21, and 28 days. Participants were randomly assigned to wear a placebo or nicotine patch for 4 weeks (3.5 mg/day during weeks 1 and 4; 7 mg/day during weeks 2 and 3). The final sample consisted of 11 nonsmokers with a mean baseline CES-D score of 27.36 (SD=10.53). RESULTS Salivary nicotine levels indicated the majority of participants were compliant with treatment. Acute nicotine did not alter mood. After adjusting for baseline values, chronic nicotine resulted in a significant decline in CES-D scores at day 8 (3.5 mg/day), but returned to placebo levels by the last visit. This return to baseline levels was coincident with a decrease in nicotine administration from 7 to 3.5 mg/day. A similar trend for improved response inhibition as measured by the Conners Continuous Performance Task was also observed. Reported side effects were infrequent and minimal. CONCLUSION These findings suggest a role for nicotinic receptor systems in the pathophysiology of depression and that nicotinic compounds should be evaluated for treating depression symptoms.

Abstract
AIMS To compare the psychometric properties of three cigarette withdrawal scales. DESIGN An internet cohort study. PARTICIPANTS Each of 4,644 current (44%), former (49%) and never smokers (7%) completed the three scales via the internet. A subsample completed the scales again after 14 days (n=1309), and indicated their smoking status after 42 days (n=1431). MEASUREMENTS The Cigarette Withdrawal Scale (CWS), the Wisconsin Withdrawal Scale (WWS) and the Minnesota Withdrawal Form (MWF). FINDINGS All three scales covered the main elements in the Diagnostic and Statistical Manual version IV (DSM-IV) and the International Classification of Diseases version 10 (ICD-10) definitions of tobacco withdrawal, but WWS did not cover weight gain. Factor analyses indicated that only six factors were present in WWS, instead of the expected seven factors. Cronbach's alpha coefficients (0.76-0.93) were high for all scales. Test-retest coefficients were in the range of 0.66-0.86 for CWS and WWS, but were somewhat lower for some MWF items (range 0.52-0.80). In 324 ex-smokers who had quit smoking 31 days or less before baseline, craving predicted relapse at 14-day follow-up (CWS: odds ratio=1.53 per point, P=0.003; WWS: odds ratio=1.40, P=0.04; MWF: odds ratio=1.49, P=0.002). In 34 baseline smokers who had quit smoking by 14-day retest, an increase in craving (WWS and MWF), depressed mood (MWF) and difficulty concentrating (WWS) between baseline and retest predicted relapse at 42-day follow-up. In terms of construct validity, scales performed similarly, but performance on some key tests (e.g. withdrawal will increase post-cessation) were inadequate, due perhaps to methodological limitations. CONCLUSIONS No scale showed a decisive advantage over the others. MWF has the advantage of brevity.

Abstract
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 > or = 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.

Abstract
Using ambulatory methods for 1 day of monitoring, the authors of this study investigated the association between smoking and situational cues in 63 smokers with posttraumatic stress disorder (PTSD) and 32 smokers without PTSD. Generalized estimating equations contrasted 682 smoking and 444 nonsmoking situations by group status. Smoking was strongly related to craving, positive and negative affect, PTSD symptoms, restlessness, and several situational variables among PTSD smokers. For non-PTSD smokers, the only significant antecedent variables for smoking were craving, drinking coffee, being alone, not being with family, not working, and being around others who were smoking. These results are consistent with previous ambulatory findings regarding mood in smokers but also underscore that, in certain populations, mood and symptom variables may be significantly associated with ad lib smoking.

Abstract
BACKGROUND Material or financial incentives may be used in an attempt to reinforce behaviour change, including smoking cessation. They have been widely used in workplace smoking cessation programmes, and to a lesser extent within community programmes. Quit and Win contests are the subject of a companion review. OBJECTIVES To determine whether competitions and incentives lead to higher long-term quit rates. We also set out to examine the relationship between incentives and participation rates. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group Specialized Register, with additional searches of MEDLINE (January 1966 to September 2004), EMBASE (1980 to 2004/8), CINAHL (1982 to 2004/8) and PsycINFO (1872 to 2004/6). Search terms included incentive*, competition*, contest*, reward*, prize*, contingent payment*, deposit contract*. SELECTION CRITERIA We considered randomized controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to experimental or control conditions. We also considered controlled studies with baseline and post-intervention measures. DATA COLLECTION AND ANALYSIS Data were extracted by one author and checked by the second. We contacted study authors for additional data where necessary. The main outcome measure was abstinence from smoking for at least six months from the start of the intervention. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Where possible we performed meta-analysis using a generic inverse variance model, grouped by timed endpoints, but not pooled across the subgroups. MAIN RESULTS Fifteen studies met our inclusion criteria. None of the studies demonstrated significantly higher quit rates for the incentives group than for the control group beyond the six-month assessment. There was no clear evidence that participants who committed their own money to the programme did better than those who did not, or that different types of incentives were more or less effective. There is some evidence that although cessation rates have not been shown to differ significantly, recruitment rates can be improved by rewarding participation, which may be expected to deliver higher absolute numbers of successful quitters. Cost effectiveness analysis is not appropriate to this review, since the efficacy of the intervention has not been demonstrated. AUTHORS' CONCLUSIONS Incentives and competitions do not appear to enhance long-term cessation rates, with early success tending to dissipate when the rewards are no longer offered. Rewarding participation and compliance in contests and cessation programmes may have more potential to deliver higher absolute numbers of quitters.

Abstract
BACKGROUND Research showed that the widely used Fagerstrom test for nicotine dependence (FTND) does not cover important aspects of dependence. A new test, the cigarette dependence scale (CDS-12), covers the main elements in DSM-IV and ICD-10 definitions of dependence. We compared the psychometrics of CDS-12, FTND, and CDS-5 and the heaviness of smoking index (HSI), which are short versions of CDS-12 and FTND, respectively. METHODS Internet survey in 2002-2003. Participants were invited one month after answering the first survey to answer a second survey on smoking status and withdrawal symptoms. RESULTS Eight hundred two smokers answered both surveys. Cronbach's alpha coefficients were higher for CDS-12 (0.91) and CDS-5 (0.77) than for FTND (0.68) and HSI (0.63). Among 231 smokers who quit smoking at follow-up, higher baseline CDS-12 scores predicted higher withdrawal ratings at follow-up, for all withdrawal symptoms except appetite. FTND and HSI predicted higher craving in quitters, but did not predict the intensity of other withdrawal symptoms. Neither CDS-5, FTND or HSI predicted smoking cessation, but higher CDS-12 scores marginally predicted smoking cessation at follow-up (area under the receiver operating characteristic (ROC) curve = 0.55, 95% confidence interval = 0.51-0.59). CONCLUSIONS CDS-12 had better content validity and internal consistency than FTND and was a slightly better predictor of withdrawal symptoms. Unexpectedly, higher (not lower) CDS-12 scores predicted subsequent smoking cessation, perhaps because endorsement of some CDS-12 items implies accepting that one is dependent, which in turn could reflect motivation to quit. CDS-12 may represent an alternative to FTND for measuring cigarette dependence.

Abstract
Because few tobacco withdrawal scales have been submitted to appropriate validity analyses, we sought to develop and assess the validity of a new, self-administered scale measuring cigarette withdrawal symptoms. We generated the instrument content by conducting a qualitative survey of 404 smokers and ex-smokers. Then we tested 61 items on the Internet in 3,050 smokers and ex-smokers. Subsamples provided comprehensive retest data after 17 days (n = 1218) and smoking status after 41 days (n = 673). The study resulted in a 21-item, six-dimension scale labeled the Cigarette Withdrawal Scale (CWS-21). The six subscales cover the main components of nicotine or tobacco withdrawal in the Diagnostic and Statistical Manual of Mental Disorders and International Statistical Classification of Diseases and Related Health Problems and in qualitative data: Depression-anxiety, craving, irritability-impatience, appetite-weight gain, insomnia, and difficulty concentrating. The six scores had a satisfactory test-retest reliability (r = .60-.71) and a high internal consistency (Cronbach's alpha = .83-.96). The factor structure of the scale was robust in a bootstrap resampling procedure. In ex-smokers, all scores except appetite-weight gain and insomnia predicted relapse at 41-day follow-up. In recent ex-smokers who had quit smoking less than 14 days before baseline, all scores except appetite-weight gain decreased between baseline and the 17-day retest. In baseline ex-smokers who relapsed to smoking at the 17-day retest, appetite-weight gain decreased and craving increased between baseline and retest. CWS-21 is a reliable, valid, multidimensional measure of cigarette withdrawal symptoms that is sensitive to change over time and predicts relapse to smoking.

Abstract
The authors compared simultaneous versus sequential approaches to multiple health behavior change in diet, exercise, and cigarette smoking. Female regular smokers (N = 315) randomized to 3 conditions received 16 weeks of behavioral smoking treatment, quit smoking at Week 5, and were followed for 9 months after quit date. Weight management was omitted for control and was added to the 1st 8 weeks for early diet (ED) and the final 8 weeks for late diet (LD). ED lacked lasting effect on weight gain, whereas LD initially lacked but gradually acquired a weight-suppression effect that stabilized (p = .004). Behavioral weight control did not undermine smoking cessation and, when initiated after the smoking quit date, slowed the rate of weight gain, supporting a sequential approach.

Abstract
BACKGROUND As part of a prospective study of relapse to smoking among previously resected lung cancer patients, we conducted a retrospective survey to examine factors that may contribute to relapse. METHODS Patients who had smoked within 3 months before surgery completed measures assessing demographic characteristics, smoking urges, depression, social support, and psychological reactance. RESULTS Of 43 participants, 19 had relapsed at some point since surgery and 13 were currently smoking. Patients were at relatively low risk of relapse immediately following hospitalization, but at greater risk beginning 2 months later. Younger age and lower educational level predicted current smoking and shorter time to relapse. Craving to smoke was measured as: Appetitive urge (anticipation of pleasure) and Aversive urge (avoidance of negative affect). Both were greater among current smokers. Aversive urge was significantly correlated with depression. Those high on both psychological reactance and Directive social support had heightened Appetitive urges. CONCLUSION Among lung cancer patients, relapse to smoking may be delayed several months but remains a problem. Appetitive and Aversive motivational pathways and associated urges appear useful in organizing study of the role of psychosocial factors such as depression and social support in relapse to smoking in this group.

Abstract
Besides nicotine, other chemicals in tobacco smoke, such as norharman, may contribute to the addictive properties of cigarettes. More specifically, elevated blood plasma levels of norharman may reduce feelings of craving among tobacco-dependent individuals. To test this hypothesis, plasma concentrations of norharman were measured in 38 male smokers (at least 15 cigarettes per day) at three time-points on 3 different days spread over a 4-month period. The first measurement (T0) was conducted in the morning at 8.30 a.m., after 12 hours of smoking abstinence. The T1 and T2 measurements were conducted at 13.00 p.m. and 16.30 p.m., during a period of ad libitum smoking (after the T0 measurement, participants were not restricted in their smoking behaviour). At each of the nine time-points, craving was assessed by means of a shortened version of the Questionnaire of Smoking Urges. The Fagerström Test of Nicotine Dependence was used to obtain an indication of nicotine dependence. The results showed that, after a period of smoking abstinence, craving was stronger in those with a high tobacco dependence than in those with a low tobacco dependence. After resumption of smoking, craving declined to a similar low level in both low and high dependent smokers. Measurements during periods of ad libitum smoking indicate that plasma levels of norharman are related negatively to craving among low nicotine-dependent smokers, but not among high dependent smokers.

Abstract
Five parameters of postcessation smoking withdrawal variability derived from clinical data (T. M. Piasecki, D. E. Jorenby, S. S. Smith, M. C. Fiore, & T. B. Baker, 2003a, 2003b) were predicted from baseline measures and pharmacotherapy assignment. Smokers who were more dependent, older, and high in negative affect reported more severe withdrawal. Women, heavier smokers, and those with a history of depression reported more variable symptoms. Smokers treated with nicotine patch, bupropion, or both reported less severe withdrawal than did those given placebo, but medication did not affect the slope of symptoms over time, day-to-day variability of symptoms, or the size of acute changes in symptoms associated with lapses to smoking. Prior research has shown that these symptom facets predict later relapse: thus, current pharmacotherapies may aid cessation by diminishing withdrawal severity, but they do not affect all clinically important aspects of withdrawal.

This study evaluated the relationship between precessation depressed mood and smoking abstinence and assessed the mediation of this effect by postcessation self-efficacy, urges to smoke, nicotine withdrawal, and coping behavior. The sample included 121 smokers previously treated in a randomized controlled trial involving behavior therapy and the nicotine patch. The results showed that precessation depressed mood was inversely related to 6-month abstinence. This effect remained significant after controlling for treatment, possible depression history, baseline smoking rates, and several other demographic factors. Postcessation self-efficacy, at the 2-, 4-, and 8-week postquit assessments, was the strongest mediator of the effects of precessation depressed mood on abstinence, accounting for 32%, 38%, and 48% of the effect of mood on abstinence, respectively.
