RESUMO

OBJECTIVE: Alexithymia is common among people who abuse alcohol, yet the mechanisms by which alexithymia exerts its influence remain unclear. This analysis tested a model whereby the three subscales of the Toronto Alexithymia Scale exert an indirect effect on alcohol problems through difficulties with emotion regulation and psychological distress. METHOD: Men and women (n = 141) seeking alcohol use disorder (AUD) treatment completed the Toronto Alexithymia Scale, the Difficulties with Emotion Regulation Scale, the Brief Symptom Inventory, the Short Inventory of Problems, and the Alcohol Dependence Scale. RESULTS: The Difficulty Identifying Feelings subscale of the Toronto Alexithymia Scale was positively associated with alcohol problems through emotion dysregulation and psychological distress. The other two subscales, Difficulty Describing Feelings and Externally oriented Thinking, were not associated with any other variables. CONCLUSION: People with alexithymia may consume alcohol to help regulate undifferentiated states of emotional arousal. Given the prevalence of alexithymia among people who abuse alcohol, treatment supplements that enhance the identification of emotions are needed.

RESUMO

Background: Many women continue to smoke during pregnancy, despite known risks, often in response to negative affect. Recent scholarship has begun to examine factors that decrease the success of behavioral treatments for smoking cessation in pregnancy, which are the preferred interventions. Alexithymia is one factor that may interfere with smoking cessation interventions. Alexithymia restricts access to emotional information and increases propensity toward maladaptive behaviors, including smoking. However, mechanisms underlying such effects are largely unknown. Objectives: Using data from a longitudinal treatment study, the present research examined difficulties with emotion regulation as a potential mechanism linking alexithymia and smoking. Pregnant smokers (n = 73; mean age = 24.78; SD = 4.50) completed measures related to alexithymia, smoking, emotion regulation, depression, anxiety, and anger at baseline and then again following eight sessions of Cognitive-Behavioral Smoking Cessation Treatment. Results: Nearly 40% of the sample met the criteria for alexithymia. The alexithymia group reported higher depression, anxiety, and anger. They also reported more difficulties with emotion regulation. In a path analysis, baseline alexithymia had a significant positive indirect effect on number of cigarettes smoked at the end of treatment through difficulties with emotion regulation. Conclusions/Importance: Similar to other studies, alexithymia limits the understanding of emotional information necessary for selection and implementation of adaptive coping responses. Our results extend the literature by suggesting that smoking may be an attempt to manage undifferentiated and unpleasant sensations created by alexithymia.

RESUMO

BACKGROUND: Few studies have focused on behavioral changes that occur prior to entering treatment for an alcohol use disorder (AUD). In 2 studies (Psychol Addict Behav, 27, 2013, 1159; J Stud Alcohol, 66, 2005, 369), pretreatment reductions in alcohol use were associated with better treatment outcomes. Identifying patterns of pretreatment change has the potential to inform clinical decision making. METHODS: This study sought to identify pretreatment change trajectories in individuals seeking outpatient treatment for AUD (N = 205) using finite mixture modeling based on changes in number of days abstinent per week (NDA). RESULTS: The analysis identified 3 pretreatment trajectory classes. Class 1 (High Abstinence-Minimal Increase; HA-MI) (n = 64; 31.2%) reported a high level of pretreatment NDA with minimal change during an 8-week pretreatment interval. Class 2 (Low Abstinence-Steady Increase; LA-SI) (n = 73; 35.6%) reported a low level of pretreatment NDA followed by a steady increase beginning 2 weeks prior to the phone screen. Class 3 (Nonabstinent-Accelerated Increase; NA-AI) (n = 68; 33.2%) reported no or very low levels of pretreatment NDA but demonstrated an increase following the phone screen. With regard to within-treatment change, Class 1 demonstrated the least and Class 3 demonstrated the most change in NDA. From baseline to 6-month follow-up, Class 3 added 2.31 abstinent days per week, Class 2 added 0.69 days, and Class 1 added 0.63 days. The increase in NDA for Class 3 was significantly different from the other 2 classes; however, Class 3 reported fewer overall days abstinent at 6-month follow-up. CONCLUSIONS: Study results have clinical and research implications including recommended changes to treatment protocols and research designs. Understanding the impact of pretreatment trajectories of alcohol use on within-treatment and posttreatment outcomes may provide important information about adapting treatment to increase efficiency and effectiveness.

RESUMO

INTRODUCTION: Negative affect has been identified as a factor influencing continued smoking during pregnancy. In this study, a multi-component emotion regulation intervention was developed to address negative emotional smoking triggers and pilot-tested among low-income pregnant smokers. Treatment feasibility and acceptability, cotinine-verified rates of smoking cessation, and self-report of mean cigarettes smoked were assessed. METHODS: Pregnant smokers who self-reported smoking in response to negative affect (N = 70) were randomly assigned to receive one of two 8-session interventions: (1) emotion regulation treatment combined with standard cognitive-behavioral smoking cessation (ERT + CBT) or (2) a health and lifestyle plus standard smoking cessation active control (HLS + CBT). Outcomes for the 4-month period following the quit date are reported. RESULTS: Treatment attendance and subjective ratings provide evidence for the feasibility and acceptability of the ERT + CBT intervention. Compared with the HLS + CBT control condition, the ERT + CBT condition demonstrated higher abstinence rates at 2 months (ERT + CBT = 23% vs. HLS + CBT = 0%, OR = 13.51; 95% CI = 0.70-261.59) and 4 months (ERT = 18% vs. HLS = 5%; OR = 2.98; 95% CI = 0.39-22.72) post-quit. Mean number of cigarettes per day was significantly lower in ERT + CBT at 2 months (ERT + CBT = 2.73 (3.35) vs. HLS + CBT = 5.84 (6.24); p = .05) but not at 4 months (ERT + CBT = 2.15 (3.17) vs. HLS + CBT = 5.18 (2.88); p = .06) post-quit. CONCLUSIONS: The development and initial test of the ERT + CBT intervention supports its feasibility and acceptability in this difficult-to-treat population. Further development and testing in a Stage II randomized clinical trial are warranted. IMPLICATIONS: Negative affect has been identified as a motivator for continued smoking during pregnancy. To date, smoking cessation interventions for pregnant smokers have not specifically addressed the role of negative affect as a smoking trigger. This treatment development pilot study provides support for the feasibility and acceptability of a multi-component ERT + CBT for low-income pregnant smokers who self-report smoking in response to negative affect. Study findings support further testing in a fully-powered Stage II efficacy trial powered to assess mediators and moderators of treatment effects.

RESUMO

Homework is widely used in cognitive behavioral therapy (CBT) for alcohol use disorder (AUD). Theoretically, homework helps clients generalize skills acquired during treatment to their daily lives. However, clinical trials methodology has typically employed pre- and post-treatment assessments which has made evaluating the contribution of homework to behavior change a challenge. The current study leveraged daily diary data from a clinical trial of CBT for AUD to parse within- and between-person associations of mindfulness homework practice and alcohol consumption. Adults seeking treatment for AUD (N = 97) completed 12 treatment sessions and 84 consecutive daily smartphone surveys. Each day, participants reported on the frequency of prior day's formal and informal mindfulness homework practice, the duration of prior day's formal mindfulness practice, and prior day's alcohol consumption. Multilevel models tested within- and between-person associations of mindfulness homework practice with the odds of drinking and heavy drinking, accounting for prior day's alcohol use. Results revealed that greater-than-usual frequency and duration of formal daily mindfulness homework practice, but not informal mindfulness practice, were associated with lower odds of a drinking day. Further, greater-than-usual duration of formal daily mindfulness homework practice, but not frequency of mindfulness practice (formal or informal), was associated with lower odds of a heavy drinking day. Results suggest that formal daily mindfulness homework practice may be beneficial and extend the literature by demonstrating that it coincides with reduced drinking and heavy drinking odds within-persons during AUD treatment. Apprising AUD clients of the potential value of homework may help boost its uptake.

RESUMO

OBJECTIVE: To better understand the timing and unique contribution of four potential mechanisms of behavior change (MOBC) during alcohol use disorder (AUD) treatment (negative affect, positive affect, alcohol craving, and adaptive alcohol coping), we used a time-varying effect modeling analytic approach to examine the change trajectories of alcohol abstinence, heavy drinking, the hypothesized MOBCs, and the time-varying associations between the MOBCs and alcohol outcomes. METHOD: Participants (N = 181; Mage = 50.8 years, SD = 10.6; 51% women; 93.5% Caucasian) were enrolled in a 12-week randomized clinical trial of cognitive behavioral outpatient treatment program for AUD. For 84 consecutive days, participants provided self-reports of positive and negative affect, craving, alcohol use, and adaptive alcohol coping strategies employed. RESULTS: Throughout the 84-day treatment window, higher daily average craving levels were associated with both decreased likelihood of alcohol abstinence and increased odds of heavy drinking, whereas higher adaptive alcohol coping was associated with increased odds of abstinence and decreased odds of heavy drinking. Higher negative affect was associated with decreased odds of abstinence in the first 10 days of treatment and increased odds of heavy drinking before Day 4 or Day 5. Higher positive affect was associated with decreased odds of heavy drinking during the first 4 or 5 days. CONCLUSIONS: The differential time-varying associations between negative affect, positive affect, alcohol craving, adaptive alcohol coping, and alcohol use provide insights into how and when each of the MOBCs is active during AUD treatment. These findings can help optimize the efficacy of future AUD treatments. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

Emotion differentiation refers to cognitively distinguishing among discrete, same-valenced emotions. Negative emotion differentiation (NED) is a transdiagnostic indicator of emotional functioning. The role of positive emotion differentiation (PED) in clinical disorders, including alcohol use disorder (AUD), is less understood. Further, despite consensus that emotions are highly variable, little is known about within-person fluctuations in NED/PED. The current study leveraged 84 consecutive daily smartphone surveys from participants (N = 181) in a clinical trial of cognitive behavioral therapy for AUD to investigate whether between-person differences in overall NED/PED, or within-person variability in daily NED/PED, were associated with affect intensity, craving, drinking, and heavy drinking in daily life. Subsequent analyses explored whether associations were moderated by baseline alexithymia. At the between-persons level, greater average PED, but not NED, was associated with lower heavy drinking odds. At the within-persons level, higher-than-usual PED was associated with lower negative affect and odds of any drinking. Individuals with baseline alexithymia had stronger negative within-person associations between daily NED and both any and heavy drinking. PED is a skill linked to less alcohol use between- and within-persons irrespective of baseline alexithymia, whereas greater daily NED appears especially important for reduced alcohol use among individuals with co-morbid AUD and alexithymia.

RESUMO

BACKGROUND: Pretreatment reductions in drinking are well documented and have been demonstrated to predict posttreatment drinking outcomes. Making use of the predictive value of pretreatment change has great appeal in settings that place a premium on efficient clinical decisions regarding appropriate type and intensity of treatment. METHODS: This study investigates whether different types and intensities of treatment are appropriate and beneficial for individuals entering treatment for an alcohol use disorder (AUD; N = 201) who make more vs. less pretreatment change in their drinking during a 2-month pretreatment period. Based on an algorithm derived from pilot research, we derived two independent pretreatment change arms that we called Substantial Change and Minimal Change. Each arm was a parallel, sequentially randomized design consisting of a treatment group and an active control. The Substantial Change arm compared six sessions of relapse prevention treatment (RPT) with 12 sessions of cognitive behavioral therapy for AUD (CBT) as an active control. Both CBT and RPT occurred over a 12-week period. The Minimal Change arm compared 12 sessions of an integrated motivational intervention combined with CBT (MI/CBT) with 12 sessions of CBT as an active control. The outcome variables were changes in number of days abstinent (NDA) and number of days heavy drinking (NDH) per week. RESULTS: For the Substantial Change arm, a noninferiority analysis revealed that six sessions of RPT were noninferior to 12 sessions of CBT at each posttreatment assessment for both NDA and NDH. For the Minimal Change arm, a superiority analysis failed to detect that MI/CBT was superior to CBT at any posttreatment assessment for both NDA and NDH. CONCLUSIONS: In the substantial change arm, results suggest that offering a less intensive initial treatment, like RPT, may lower costs and conserve clinical resources. In the Minimal Change arm, results indicate the need to continue searching for a treatment or treatment enhancements to improve alcohol outcomes.

RESUMO

OBJECTIVE: Research has identified several potential mechanisms of behavior change (MOBCs) in cognitive-behavioral therapy for alcohol use disorder, including alcohol abstinence self-efficacy (AASE), negative affect (NA), and positive affect (PA). However, little is known about when MOBCs affect clinical outcomes during alcohol use disorder treatment. Such information could advance MOBC research by identifying relationships between specific treatment content and variations in MOBCs. This study examined three MOBCs simultaneously to determine their timing and relative influence on percent days abstinent (PDA) and drinks per day (DPD). METHOD: Data were derived from a parent study assessing pretreatment change in drinking. Participants (n = 205) received 12 sessions of cognitive-behavioral therapy for alcohol use disorder. AASE, NA, and PA were measured at each treatment session, and time-varying effect models (TVEM) were used to examine their association with PDA and DPD. RESULTS: All three MOBCs were associated with PDA and DPD but varied with regard to time course, strength, and direction. For PDA, AASE was positively associated throughout treatment, NA was negatively associated from Sessions 1 to 10, and PA was positively associated from Sessions 1 to 3 and 11 to 12. For DPD, AASE was positively associated from Session 5 to the end of treatment, NA was positively associated throughout treatment although the strength of the association varied and was strongest at the beginning of treatment, and PA was positively associated from Sessions 5 to 12. CONCLUSIONS: Results show that MOBCs exert their effects at different times during treatment. In addition to replicating these results, future research should attempt to manipulate MOBCs directly and examine their influence on alcohol outcomes.

RESUMO

RATIONALE: There is limited understanding regarding how various e-cigarette flavorings may influence the behavior of non-regular e-cigarette users who are regular cigarette smokers. OBJECTIVES: To assess differences in nicotine delivery, puffing topography, subjective effects, and user satisfaction from different flavored e-liquids. METHODS: Eighteen daily smokers (average age, 44.1 ± 7.0; 9 males; average CPD, 13.0 ± 5.8) smoked their tobacco cigarettes during an initial visit and returned five times to try an e-cigarette (eGo type) refilled with a nicotine solution (24 mg/ml) of five different flavors: cherry, tobacco, espresso, menthol, and vanilla (randomized order). Assessments at each visit included puffing topography, blood samples for nicotine analysis, and subjective reports of nicotine effects and flavor satisfaction. RESULTS: Vaping different flavors resulted in different levels of plasma nicotine. The flavor producing the highest plasma nicotine concentration (Cmax) was cherry (median 21.2 ng/ml), which was not significantly different than nicotine delivery from a combustible cigarette (29.2 ng/ml, p > .05). Vanilla e-liquid produced the lowest Cmax (9.7 ng/ml), and participants tended to puff less frequently on vanilla compared to tobacco flavor (p = .013). Flavors did not differ significantly in the speed of nicotine delivery (Tmax). During controlled use, puff duration for all flavors was significantly longer than a combustible cigarette (p < 0.05). After controlling for nicotine delivery, significant differences in flavor enjoyment were detected. Menthol flavored e-liquid was rated as more enjoyable than vanilla and tobacco flavored e-liquids (p < 0.05). CONCLUSIONS: Flavors tested in this study yielded different patterns of nicotine delivery and led to differences in reduction in smoking urges.

RESUMO

Etiological models of alcohol use that highlight the role of negative affect and depression have not been applied to the association of suicidality and alcohol use. The authors examined whether a motivational model of alcohol use could be applied to understand the relationship between suicidal ideation and alcohol outcomes in a sample of underage college drinkers who had a history of passive suicidal ideation (n = 91). In this cross-sectional study, regression analyses were conducted to examine whether drinking to cope with negative affect statistically mediated or was an intervening variable in the association between suicidal ideation and alcohol outcomes. Results revealed that drinking to cope was a significant intervening variable in the relationships between suicidal ideation and alcohol consumption, heavy episodic drinking, and alcohol problems, even while controlling for depression. These results suggest that the relationship between suicidal ideation and alcohol outcomes may be due to individuals using alcohol to regulate or escape the distress associated with suicidal ideation. Consideration of alcohol-related models can improve the conceptualization of research on suicidality and alcohol use.

RESUMO

Approximately 15% of US women currently smoke during pregnancy. An important step toward providing effective smoking cessation interventions during pregnancy is to identify individuals who are more likely to encounter difficulty quitting. Pregnant smokers frequently report smoking in response to intrapersonal factors (e.g., negative emotions), but successful cessation attempts can also be influenced by interpersonal factors (i.e., influence from close others). This study examined the association between emotion regulation difficulties, positive and negative social control (e.g., encouragement, criticism), and smoking cessation-related variables (i.e., smoking quantity, withdrawal symptoms) among pregnant smokers. Data were drawn from the pretreatment wave of a smoking cessation trial enrolling low-income pregnant women who self-reported smoking in response to negative affect (N = 73). Greater emotion regulation difficulties were related to greater smoking urges (b = 0.295, p = .042) and withdrawal symptoms (b = 0.085, p = .003). Additionally, more negative social control from close others was related to fewer smoking days (b = -0.614, p = .042) and higher smoking abstinence self-efficacy (b = 0.017, p = .002). More positive social control from close others interacted with negative affect smoking (b = -0.052, p = .043); the association between negative affect smoking and nicotine dependence (b = 0.812, p < .001) only occurred at low levels of positive social control. Findings suggest that emotion regulation difficulties may contribute to smoking during pregnancy by exacerbating women's negative experiences related to smoking cessation attempts. Negative social control was related to lower smoking frequency and greater confidence in quitting smoking, suggesting that it may assist pregnant smokers' cessation efforts. Positive social control buffered women from the effects of negative affect smoking on nicotine dependence. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01163864.

RESUMO

BACKGROUND AND AIMS: Vaporized nicotine products (VNPs) can vary in important characteristics including size, shape, flavor and nicotine yield. We examined whether complex interactions among these characteristics could affect smokers' VNP perceptions and usage patterns. DESIGN: A within-subject randomized cross-over trial. SETTING: Roswell Park Comprehensive Cancer Center, Buffalo, NY, USA. PARTICIPANTS: Eighteen daily cigarette smokers. MEASUREMENTS: Participants attended eight weekly visits during which they sampled six different VNPs (disposable, rechargeable, eGO, mod, e-Cigar and e-Pipe) with tobacco-flavored e-liquid. Prior to device use, participants completed product-ranking questionnaires. Participants completed controlled puffing sessions during each of the six trials, after which satisfaction questionnaires were completed and blood samples were taken. FINDINGS: Initial perceptions showed that the smallest device (disposable) was ranked as safer compared with a larger device (e-Pipe) (P < 0.05). Participants rated the eGO and mod devices higher on satisfaction and enjoyment from use, taste, pleasantness, harshness ('throat hit') and speed of effect, but lower on perceived health risk and embarrassment from use (P < 0.05). All devices had a lower Cmax than the combustible cigarette (P < 0.05), but there were differences among devices (P < 0.05). The mod, e-Pipe and eGO provided the highest amount of perceived smoking urge relief, and this correlated strongly with Cmax across all devices (R2  = 0.8614, P = 0.007). The perceived speed of urge relief was not correlated with Tmax (R2  = 0.0035, P = 0.911) CONCLUSIONS: Daily cigarette smokers testing six types of vaporized nicotine products (VNPs) reported that they varied in taste, amount of withdrawal relief, harshness, embarrassment from use, perceived health risk and subjective and objective nicotine delivery. The eGO and mod models have properties that may make them most effective for cigarette substitution among smokers who intend to switch to a VNP.

RESUMO

The authors assessed temporal relationships among alcohol use, aggression, and mood using daily data from 179 college women. Participants called an interactive voice response system over an 8-week period. The odds of experiencing verbal, sexual, and physical aggression (odd ratios = 2.25, 19.44, and 11.84, respectively) were significantly higher on heavy drinking days (M = 7.46 drinks) compared to nondrinking days. Both a history of victimization and greater psychological symptom severity influenced the odds of involvement in verbal aggression. The odds of alcohol consumption were 3 times higher during the 24 hr following verbal aggression compared with days in which verbal aggression did not occur. On the day immediately following involvement in either verbal or physical aggression, positive mood decreased and negative mood increased. During the week (2-7 days) following sexual aggression, women's positive mood was decreased. These findings reinforce the need for interventions aimed at reducing heavy episodic drinking on college campuses.

RESUMO

This study examined subject-collateral reports of alcohol use among a sample of 167 dually diagnosed individuals seeking outpatient treatment at a community mental health clinic. All subjects met Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) criteria for a schizophrenia-spectrum or bipolar disorder and for alcohol abuse or dependence. Subjects were recruited within 2 weeks of treatment entry and completed measures of cognitive functioning, alcohol dependence severity, psychiatric symptoms, and quantity and frequency of substance use over the previous 60 days using the Timeline Follow-Back interview (L. C. Sobell & M. B. Sobell, 1996). They also provided a urine sample, which was screened for recent drug use. Collateral interviews were conducted by phone and included an assessment of the subject's alcohol and drug use over the same 60-day period. Collaterals also reported their confidence in the accuracy of their reports. Overall, the results indicated generally poor subject-collateral agreement. However, subject-collateral agreement appeared better for those individuals (n = 97) with negative urine drug screens. The most consistent predictor of subject-collateral discrepancy scores was subjects' recent drug use. Recommendations for enhancing the validity of self-reports of substance use in a severely mentally ill population are discussed.

Emotion regulation difficulties (ERD) are known to underlie mental health conditions including anxiety and depressive disorders and alcohol use disorder (AUD). Although AUD, mood, and anxiety disorders commonly co-occur, no study has examined the association between these disorders and ERD among AUD outpatients. In the current study, emotion regulation (ER) scores of AUD individuals with no co-occurring mental health condition were compared to the ER scores of individuals who met diagnostic criteria for co-occurring mood and/or anxiety disorders. Treatment-seeking AUD individuals (N=77) completed measures of emotion regulation, alcohol use and psychological functioning prior to beginning a 12-week outpatient cognitive-behaviorally oriented alcohol treatment program. Individuals were classified as having no co-occurring mood or anxiety disorder (AUD-0, n=24), one co-occurring disorder (AUD-1, n=34), or two or more co-occurring disorders (AUD-2, n=19). Between-group differences in emotion regulation, quantity/frequency of alcohol consumption, positive and negative affect, affective drinking situations, negative mood regulation expectancies, distress tolerance, alexithymia, trait mindfulness, and psychological symptom severity were examined. Compared with the AUD-0 group, the AUD-2 group reported significantly greater ERD, psychiatric distress and alcohol consumption, more frequent drinking in response to negative affect situations, greater interference from negative emotions, and less use of mindfulness skills. The AUD-1 group differed from AUD-0 group only on the DERS lack of emotional awareness (Aware) subscale. Emotion regulation scores in the AUD-0 group were comparable to those previously reported for general community samples, whereas levels of ERD in the AUD-1 and AUD-2 were similar to those found in other clinical samples. Implications for the inclusion of ER interventions among AUD patients who might most benefit from such an intervention are discussed.

RESUMO

Malt liquor (ML) is a cheap, high alcohol content beverage that is marketed to appeal to young adults. Findings from the few published studies of ML use suggest that it may be associated with excessive drinking, alcohol problems, and the use of illicit drugs. The authors conducted separate hierarchical multiple regressions to examine the role of ML use and psychosocial variables (e.g., personality, ML motives) in alcohol-related problems and marijuana use. Demographic characteristics served as controls. The sample consisted of 639 (456 men, 183 women) young adults (M = 22.9 years, SD = 4.2) who regularly (> or =40 oz/week) consumed ML. ML use significantly and positively predicted alcohol problems, ML-specific problems, and marijuana use, above and beyond their associations with typical alcohol use. Marijuana was the illicit drug of choice, and 46% reported concurrent use of marijuana and ML. Those who concurrently used ML and marijuana began drinking at a younger age and reported more substance use (particularly marijuana) and more alcohol-related problems than did non-concurrent users. These results suggest that ML use may represent a risk for alcohol problems and marijuana use.

RESUMO

Pavlovian conditioning models have led to cue-exposure treatments for drug abuse. However, conditioned responding to drug stimuli can return (be renewed) following treatment. Animal research and a previous study of social drinkers indicated that extinction is highly context dependent but that renewal could be reduced by the inclusion of a cue from the extinction context. This study extends this research to a clinical sample. Alcohol-dependent outpatients (N = 143) completed an extinction trial to reduce craving and salivation responses to alcohol cues. They were then randomized to renewal tests in either the same context as extinction, a different context, the different context containing an extinction cue, or the different context with cue plus a manipulation to increase the salience of the cue. Contrary to predictions, the different context did not produce the expected renewal effect. Although the generalization of extinction effects beyond the cue-exposure context is a positive clinical finding, it is inconsistent with basic research findings on the context dependence of extinction. Possible explanations for this inconsistency are discussed.

RESUMO

The supersensitivity hypothesis posits that individuals with a severe mental illness (i.e., schizophrenia and bipolar disorder; SMI) are more likely to be diagnosed with a substance abuse as opposed to a substance dependence diagnosis, and experience greater negative consequences associated with substance use at lower levels of consumption, as compared with non-SMI substance abusers. This is the first known study to test this hypothesis with a control group of non-SMI substance abusing individuals. Forty-two individuals with only a substance use disorder (SUD-only) and 53 dually diagnosed individuals (DD) were compared on measures of substance use, alcohol and drug dependence, negative consequences, substance use outcome expectancies, and motivation for change. A third group of SMI-only individuals (i.e., no SUD; n=35) were also recruited and all three groups were compared on psychological symptoms. Substance use, negative consequences, substance use outcome expectancies, motivation for change, and severity of alcohol and drug dependence were not found to differ significantly between the DD and SUD-only groups. However, the DD group had significantly greater levels of psychological symptoms, as compared with the SMI-only and SUD-only groups. Overall, this study does not provide support for the supersensitivity hypothesis.
