Retraction of "Event-level risk for negative alcohol consequences in emerging adults: The role of affect, motivation, and context" by Waddell et al. (2024).

Reports the retraction of "Event-level risk for negative alcohol consequences in emerging adults: The role of affect, motivation, and context" by Jack T. Waddell, Scott E. King, Sarah A. Okey and William R. Corbin (Psychology of Addictive Behaviors, 2024[Feb], Vol 38[1], 8-18). This article is being retracted at the request of the publisher, and the editor and all authors of the original article consented. This article was published in error, as it is a first stage Registered Report that has received in-principle acceptance. Given the workflow of a Registered Report, the first journal publication appears after data collection and results have been reported in the second stage Registered Report submission (see workflow at https://www.cos.io/initiatives/registered-reports). This stage one article is being removed from the literature to avoid confusion and will instead be preregistered as a Registered Report Protocol Preregistration (https://osf.io/7euzd/). (The following abstract of the original article appeared in record 2022-80654-001.) Objective: Decades of research has found support for the motivational model of alcohol use, such that positive/negative affect are indirectly associated with drinking behavior through drinking motives. However, research on event-level drinking motives is in its nascent stage, and studies have yet to consider how drinking context plays a role in the motivational pathway to both event- and person-level drinking behavior. Therefore, the present study seeks to test whether drinking context mediates the effect of affect and motivation on drinking outcomes at both the event- and person-level. Method: Data for this Stage 1 Registered Report will come from a recently completed ecological momentary assessment (EMA) study in emerging adults. The study collected data on 131 emerging adults, of whom 107 reported event-level social and solitary drinking during the EMA period. Multilevel structural equation modeling will be used to test whether predrinking affect is associated with predrinking motives, and whether drinking context (social vs. solitary drinking) mediates the effect of drinking motives on drinking outcomes. Models will parse within-/between-person variance, allowing the present study to test whether drinking context serves as a mechanism of risk in the motivational model at the event-level, or solely at the between-person level. Findings will inform personalized interventions and motivational models of drinking behavior. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Event-level risk for negative alcohol consequences in emerging adults: The role of affect, motivation, and context.

Decades of research has found support for the motivational model of alcohol use at the between-person level, yet research on event-level drinking motives is in its nascent stage. Similarly, drinking context has been largely ignored in studies of day-level motives. Therefore, the present study sought to test whether drinking context mediates the relation between affect and motivation on drinking outcomes at both day and person levels. Emerging adults who drank in solitary and social settings (N = 107; 61.2% female) completed 21 days ecological momentary assessments. Affect was assessed during morning/afternoon reports; drinking motives were assessed during afternoon reports; and past-night drinking context, drinking quantity, and negative consequences were assessed during next morning reports. Two-level multilevel structural equation models tested whether within-person and between-person levels of predrinking affect were indirectly associated with negative consequences through predrinking motives, drinking context (social vs. solitary), and drinking quantity. At the day and person levels, positive affect was associated with higher social and enhancement motives. At the day level, positive affect indirectly predicted consequences through social motives, social (vs. solitary) drinking, and drinking quantity, whereas positive affect indirectly predicted consequences through enhancement motives and drinking quantity above and beyond context. At the day and person levels, negative affect was associated with coping motives, but coping was not associated with context, drinking quantity, nor consequences. Findings suggest that positive affect was linked to drinking outcomes through motives (enhancement and social) and contexts (social), whereas negative affect was not. Findings suggest that positively valenced drinking motives may be an important just-in-time intervention target. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Subtypes of prescription stimulant misuse among students: a nuanced story

ABSTRACT Research on stimulant misuse among students has been rising. These medicines are generally prescribed to treat ADHD, but they are also used by students to enhance their academic performance. To date, qualitative research on the topic is limited, specifically in understanding the process of misuse, i.e. the motivations embedded in a particular academic and social context driving students’ decision to use. The aim of this research was to develop subtypes by disentangling patterns in the process of stimulant misuse. We conducted a focus group (n = 5) and semi-structured interviews (n = 28) with Flemish university students who had misused stimulants during their academic career. We employed abductive analysis principles, in which we build on Conrad’s medicalization and enhancement theory and Cox and Klinger’s motivational model of alcohol use. Two dimensions were key in differentiating theoretically meaningful subtypes: (1) perception of academic need and (2) frequency of use. The normalization subtype indicates having concentration problems and structurally uses stimulants to deal with these problems; the rescue subtype is able to study without stimulants, but occasionally uses them to cope with academic demands and/or personal stressors; the experimental subtype does not have an academic need to use stimulants, but temporarily uses them out of curiosity; the performance subtype does not need the medication, but perceives it as a convenient tool to structurally facilitate academic life, e.g. to shorten the study process. Our study shows a nuanced story of students’ stimulant misuse and helps inform the development of tailored preventive measures.

An event-level evaluation of women's self-medicated drinking: The role of sexual assault severity, affect, and drinking motives.

Women with sexual assault (SA) histories report heavier and more frequent drinking. Consistent with the motivational model of alcohol use, women with SA histories may consume alcohol to both downregulate negative emotions and upregulate positive ones. The present event-level study used a Bayesian multilevel moderated mediation approach to examine the extent to which women's alcohol use and intoxication was influenced by coping and enhancement drinking motives to downregulate or upregulate affect, respectively. Women ages 21-30 were recruited from the community to participate in a larger study that included a 32-day daily diary assessment of affect, drinking motives, and alcohol use. We found consistent support for women's tendencies to be motivated to drink to cope or enhance negative or positive affect, respectively, and those drinking motives were associated with indicators of increased drinking. Becoming intoxicated to downregulate negative emotion was common and this pathway was particularly strong for women who reported more severe SA histories. Although women with more severe SA histories were generally more likely to drink more, they were not likely to do so as a way to enhance positive experiences. Alcohol interventions that provide adaptive regulatory strategies are needed for women who experience increased negative or positive affect, with a particular focus on self-medication for young women with more severe SA histories.

Descriptive peer drinking norms and binge drinking: Enhancement motives as a mediator and alcohol resistance self-efficacy as a moderator.

The association between descriptive norms regarding peer drinking and college students’ binge drinking has been established; however, the mediating and moderating mechanisms underlying this relationship among first-and second-year college students remain minimally explored. Drawing on social norms theory, motivational model of alcohol use, and the theory of normative social behavior, the current study investigated whether enhancement drinking motives mediated the relationship between descriptive norms regarding peer drinking and college students’ binge drinking, and whether this relationship was moderated by alcohol resistance self-efficacy. Five hundred and nineteen first-and second-year college students (Mage = 19.19 years, SD = 0.98) who were from four universities and had at least one time of heavy episodic drinking during the last year completed self-report questionnaires. After controlling for sex, age, and university variable, stronger descriptive norms regarding peer drinking were positively associated with a greater frequency of binge drinking. Enhancement drinking motives partially mediated the effects of descriptive peer drinking norms on binge drinking. Furthermore, alcohol resistance self-efficacy moderated the direct effects of descriptive peer drinking norms on binge drinking. Compared with college students who reported high alcohol resistance self-efficacy, the direct effects of descriptive peer drinking norms on binge drinking were stronger among students with low alcohol resistance self-efficacy. These findings point to the potential value of alcohol intervention approaches including efforts to help first-and second-year college students change enhancement drinking motives and increase their ability of resisting drinks in the context of pervasive peer drinking.

The Mediating Role of Avoidant and Facilitative Coping on the Relation Between Discrimination and Alcohol Use Among Transgender and Gender-Diverse Individuals.

The motivational model of alcohol use indicates that there is a relation between chronic stress and alcohol use, and that this relation is mediated by substance use to cope. However, this model has not been applied to the experiences of transgender and gender-diverse (TGD) individuals. In response, this study investigated whether facilitative (e.g., active and interpersonal coping) and avoidant (e.g., cognitive avoidance and substance use to cope) coping mediate the relation between discrimination and alcohol use. Participants include 496 TGD individuals (97 trans women, 126 trans men, and 273 nonbinary), 18-68 years of age (mean=32.09 and standard deviation=12.47), who completed a survey about health behaviors and stress. An exploratory factor analysis and confirmatory factor analysis of the Brief Coping Orientation to Problems Experienced (COPE) were conducted to determine the coping patterns of TGD individuals and multiple mediation analyses were conducted to examine whether distinct coping strategies mediated the relation between discrimination and alcohol use. Both facilitative and avoidant coping strategies were significantly related to discrimination; however, only active coping and substance use to cope were related to alcohol use. Mediation results showed that substance use to cope (i.e., an avoidant coping strategy) was the only significant mediator. Descriptive results showed nonsignificant differences between TGD gender identities regarding levels of alcohol use and engagement with coping strategies. The results indicate a clear need for interventions to reduce utilization of avoidant coping strategies among TGD individuals.

Adaptive Text Messaging for Postpartum Risky Drinking: Conceptual Model and Protocol for an Ecological Momentary Assessment Study.

BackgroundRisky drinking is prevalent among women of childbearing age. Although many women reduce their drinking during pregnancy, more than half return to prepregnancy levels during the early postpartum period. Risky drinking in new mothers may be associated with negative child and maternal health outcomes; however, new mothers are unlikely to seek treatment for risky drinking because of stigma and fear of child protective service involvement. SMS text messaging is a promising approach for reaching non–treatment-seeking new mothers at risk because of risky drinking. SMS text messaging interventions (TMIs) are empirically supported for alcohol use, but a tailored intervention for new mothers does not exist. This study aims to fill this gap by developing a just-in-time adaptive TMI for postpartum risky drinking.ObjectiveThe objectives of this paper are to present a preliminary conceptual model of postpartum risky drinking and describe the protocol for conducting an ecological momentary assessment (EMA) study with new mothers to inform the refinement of the conceptual model and development of the TMI.MethodsThis paper presents a preliminary conceptual model of postpartum risky drinking based on the motivational model of alcohol use, social cognitive theory, and temporal self-regulation theory. The model proposes three primary intervention targets: motivation, self-efficacy, and self-regulation. Theoretical and empirical literature in support of the conceptual model is described. The paper also describes procedures for a study that will collect EMA data from 30 participants recruited via social media and the perinatal Central Intake system of New Jersey. Following the baseline assessment, EMA surveys will be sent 5 times per day for 14 days. The assessment instruments and data analysis procedures are described.ResultsRecruitment is scheduled to begin in January 2022 and is anticipated to conclude in March 2022. Study results are estimated to be published in July 2022.ConclusionsThe study findings will enhance our understanding of daily and momentary fluctuations in risk and protective factors for risky drinking during the early postpartum period. The findings will be used to refine the conceptual model and inform the development of the TMI. The next steps for this work include the development of intervention components via an iterative participatory design process and testing of the resulting intervention in a pilot microrandomized trial.International Registered Report Identifier (IRRID)PRR1-10.2196/36849

Motivational pathways to problematic drinking among Latinx college drinkers.

Though Latinx drinkers experience disparities in problematic drinking, emerging mechanisms that lead to these disparities remain understudied. The objective of this study was to examine drinking motives as the most proximal pathways to problematic drinking that mediate the effects of personality and sociocultural distal antecedents among Latinx college drinkers. A total of 264 Latinx undergraduate drinkers (67% cisgender women, 31% cisgender men, 2% gender fluid/nonconforming individuals) completed a battery of self-report measures assessing problematic drinking, drinking motives, alcohol expectancies, sensation seeking, stress, campus climate, injunctive peer drinking norms, and familismo. Consistent with hypotheses, structural equation modeling revealed that coping motives were the strongest predictors of problematic drinking. Stress, campus climate, and alcohol expectancies were indirectly associated with problematic drinking through coping motives. Unexpectedly, sensation seeking had a direct effect on problematic drinking while familismo was not a protective factor. Stress and campus climate emerged as two important sociocultural antecedents associated with problematic drinking through coping motives. Findings also generally support the tenets of motivational models of alcohol use and extend their applicability to Latinx college drinkers. Results highlight the need for culturally responsive interventions that address motivational pathways to problematic drinking within the sociocultural environment in which Latinx college drinkers are embedded.

MT-aIAT: The Convergence of RT, Mouse Tracking and Computation in Memory-Detection aIAT

Overconsumption of alcohol is a major problem in western society. Why do people drink excessively despite overwhelming negative consequences? Choosing to drink is determined by the several psychological systems undergirding any motivated behavior. Drinkers’ expectations of stronger positive and weaker negative affect from drinking are the most proximal determinant of their choice to drink. More distal systems will have previously determined the nature of these expectations, such as previous biochemical reactions to alcohol, relevant personality traits, and rewards or punishments for drinking imposed by the person’s social context. Knowing these motivational determinants of excessive drinking provides insight into how to help people overcome their motivation to drink. Two kinds of interventions have evolved from the motivational model of alcohol use. One intervention trains drinkers to divert their attention away from alcohol stimuli in the environment, thereby aiming to reduce their craving for alcohol. The other intervention helps drinkers find emotional satisfaction through healthy goal pursuits, thereby reducing their need for alcohol. Promising results have been obtained with both of these interventions.

Affect and drinking behavior: Moderating effects of involuntary attention to emotion and distress tolerance.

This study tested a multiple group path model in a sample of young adults (n = 402; 233 university participant pool/169 Amazon MTurk) linking positive and negative affect to alcohol consumption and problems via enhancement and coping motives, respectively. Motivational models of alcohol use suggest that individuals drink in order to alleviate negative affective states or to enhance positive moods or feelings. Deficits in modulating attention toward emotional experience (i.e., involuntary attention to emotion [IAE]); and poor distress tolerance may contribute to maladaptive patterns of substance use (i.e., negative reinforcement). As negative affect increases, those with deficits in the ability to efficiently attend to emotions as well as the inability to withstand distress may seek more external means of regulating unwanted or intrusive emotional experiences via alcohol. It was hypothesized that involuntarily attending to one's emotions would contribute to negative reinforcement drinking and problems. Coping motives were directly associated with alcohol-related problems, while enhancement motives were directly associated with problems both directly and indirectly via alcohol consumption. The hypothesized interaction between negative affect and IAE to coping motives was conditional upon levels of distress tolerance, with the moderating effect of involuntary attention being significant at high but not low levels of distress tolerance. Distress tolerance exhibited direct, inverse associations with alcohol-related problems. This pathway was significant over and above the direct effects of both coping motives and alcohol consumption. This suggests that while tolerance for emotional distress may reduce negative reinforcement drinking, it also fosters adaptive regulation when intoxicated.

Validation and Transference of Drinking Motives Based on the Motivational Model of Alcohol Use

Validation and Transference of Drinking Motives Based on the Motivational Model of Alcohol Use

Emotional alienation as a mediator of the relationship between perceived discrimination and alcohol use among immigrant adolescents in Israel

ABSTRACTPerceived discrimination has been found to be a predictor of immigrant adolescent involvement in alcohol use, yet the psychological mechanism behind this relationship has not been well explored. Drawing on strain theory and the motivational model of alcohol use, the current study aimed to develop and test a concept of emotional alienation. In the proposed model, it is when experiences of discrimination are internalized into painful feelings of detachment, anger, rejection, and failure that the immigrant adolescent may turn to alcohol use. The study involved 365 at-risk immigrant adolescents, aged 15–19 (62% male, mean age 17.1) from the Former Soviet Union and Ethiopia in Israel, from low SES neighborhoods and community centers for youth at risk. The young people self-reported on experiences of discrimination, daily alcohol use, heavy episodic drinking (HED), and drunkenness, together with a new questionnaire examining emotional alienation developed for the study. Findings showed that experiences of alienation fully mediated the relationship between discrimination and problematic alcohol use (drunkenness and HED). In particular, feelings of self-detachment, failure, and rejection were strongly related to alcohol use. Results suggest an importance of understanding the way in which negative reactions from the host society may be internalized into destructive feelings of failure, shame, and rejection, which may lead a young person to involvement in alcohol use.

The role of substance use motives in the associations between minority stressors and substance use problems among young men who have sex with men.

Young men who have sex with men (YMSM) report higher rates of substance use than their heterosexual peers and minority stress has been posited as a risk factor for substance use. The associations between specific types of minority stress and substance use have been inconsistent throughout the literature and few studies have examined mechanisms underlying these associations. Drawing on minority stress theory and the motivational model of alcohol use, we propose that one mechanism underlying these associations may be people's motivations for using substances, including using substances to cope with negative emotions and to enhance pleasure. The goals of the current study were: (1) to examine the associations among minority stressors, substance use motives, and substance use problems; and (2) to examine substance use motives as mediators of the associations between minority stressors and substance use problems. Baseline self-report data were used from a cohort of 370 YMSM enrolled in a larger study of substance use and sexual behavior. Results indicated that using marijuana to cope mediated the association between victimization and marijuana use problems. Using other drugs to cope mediated the associations between victimization and drug use problems and between internalized stigma and drug use problems. Drinking to cope and to enhance pleasure mediated the association between internalized stigma and alcohol use problems. In sum, substance use motives, especially using substances to cope, act as mechanisms through which certain types of minority stress influence substance use problems among YMSM.

An Exploration of the Four-Factor Structure of the Drinking Motives Questionnaire-Revised Among Undergraduate Students in China

Background: College drinking has become a significant health issue in China; the current study addressed the gap that no prior research has investigated drinking motives among Chinese undergraduate students. Objectives: This study aimed to replicate the four-factor structure of the Drinking Motives Questionnaire-Revised (DMQ-R) reported for Western populations. Additionally, the relationships between drinking motives and alcohol use were investigated. Methods: In 2012, 436 participants (mean age = 20.49 and SD = 1.49; 50% male) recruited from a college in China completed a self-administered survey in their classroom setting. Drinking motives were measured by the Chinese version of the DMQ-R; three indicators of alcohol use were assessed. Factor analysis was conducted to examine the factor structure of the DMQ-R, followed by regression analysis to investigate the associations between drinking motives and alcohol-related outcomes. Results: Confirmatory factor analysis failed to replicate the measurement model tested, but exploratory factor analysis identified a similar four-dimensional factor structure. Reliability and convergent and discriminant validity of the four factors were acceptable. The results also showed that social motives were related to alcohol use and heavy drinking; conformity motives were related to alcohol use and alcohol-related problems. Enhancement motives were the strongest correlates of alcohol use; coping motives were the strongest correlates of heavy drinking and alcohol-related problems. Conclusions/Importance: The DMQ-R was a reliable and valid scale measuring four types of drinking motives among Chinese college students. Findings suggested that the motivational model of alcohol use may apply to studying college drinking in China.

Dyadic conflict, drinking to cope, and alcohol-related problems: A psychometric study and longitudinal actor-partner interdependence model.

The motivational model of alcohol use posits that individuals may consume alcohol to cope with negative affect. Conflict with others is a strong predictor of coping motives, which in turn predict alcohol-related problems. Two studies examined links between conflict, coping motives, and alcohol-related problems in emerging adult romantic dyads. It was hypothesized that the association between conflict and alcohol-related problems would be mediated by coping-depression and coping-anxiety motives. It was also hypothesized that this would be true for actor (i.e., how individual factors influence individual behaviors) and partner effects (i.e., how partner factors influence individual behaviors) and at the between- (i.e., does not vary over the study period) and within-subjects (i.e., varies over the study period) levels. Both studies examined participants currently in a romantic relationship who consumed ≥12 alcoholic drinks in the past year. Study 1 was cross-sectional using university students (N = 130 students; 86.9% female; M = 21.02 years old, SD = 3.43). Study 2 used a 4-wave, 4-week longitudinal design with romantic dyads (N = 100 dyads; 89% heterosexual; M = 22.13 years old, SD = 5.67). In Study 2, coping-depression motives emerged as the strongest mediator of the conflict-alcohol-related problems association, and findings held for actor effects but not partner effects. Supplemental analyses revealed that this mediational pathway only held among women. Within any given week, alcohol-related problems changed systematically in the same direction between romantic partners. Interventions may wish to target coping-depression drinking motives within couples in response to conflict to reduce alcohol-related problems.

Drinking motives and attentional bias to affective stimuli in problem and non-problem drinkers.

Problem drinking may reflect a maladaptive means of coping with negative emotions or enhancing positive emotions. Disorders with affective symptoms are often characterized by attentional biases for symptom-congruent emotionally valenced stimuli. Regarding addictions, coping motivated (CM) problem gamblers exhibit an attentional bias for negative stimuli, whereas enhancement motivated (EM) problem gamblers exhibit this bias for positive stimuli (Hudson, Jacques, & Stewart, 2013). We predicted that problem drinkers would show similar motive-congruent attentional biases. Problem and non-problem drinkers (n = 48 per group) completed an emotional orienting task measuring attentional biases to positive, negative, and neutral stimuli. As predicted, EM problem drinkers showed an attentional bias for positive information (i.e., reduced accuracy for positively cued trials). However, CM problem drinkers displayed a general distractibility (i.e., reduced accuracy, regardless of cue valence). The results add further support for Cooper et al.'s (1992) motivational model of alcohol use, and indicate potential motivation-matched intervention targets. (PsycINFO Database Record

Protective behavioral strategies, alcohol expectancies, and drinking motives in a model of college student drinking.

An extensive body of research asserts alcohol expectancies, or beliefs regarding the effects of alcohol, as an important influence on drinking. However, the extent to which expectancies are related to drinking motives and protective behavioral strategies (PBS) has yet to be examined. Existing alcohol mediational models suggest associations between expectancies and drinking motives as well as positive drinking motives and PBS use. Thus, it is possible that drinking motives and PBS use act as intervening factors in the relationship between expectancies and alcohol outcomes. Consequently, the cross-sectional study presented here aimed to test the indirect effect of expectancies (i.e., social facilitation) on alcohol outcomes through drinking motives and PBS use. Participants were 520 (358 female) college student drinkers with a mean age of 20.80 (SD = 4.61) years. Students completed measures of expectancies, drinking motives, PBS use, alcohol use, and alcohol-related problems. Results from structural equation modeling indicated that drinking motives and PBS mediated the relationship between social expectancies and alcohol use. In particular, expectancies were associated with greater positive drinking motives, drinking motives were associated with less PBS use, and PBS was associated with less alcohol use and fewer alcohol-related problems. Given the key role of PBS in explaining drinking outcomes in our model, active efforts to incorporate PBS in alcohol interventions may be particularly beneficial for college students. Further, our findings support the consideration of PBS use as a part of the motivational model of alcohol use in future work.

College students' daily-level reasons for not drinking.

Motivational models of alcohol use posit opposing approach and avoidance motives related to drinking, yet no micro-longitudinal study of college students has examined avoidance motives [i.e. reasons for not drinking (RND)]. This exploratory study examined daily- and person-level correlates of students' RNDs to identify factors that may inhibit alcohol use. College students (n = 1631; 54% female) participated in a 30-day daily diary study in which they reported RNDs for non-drinking evenings, as well as daily moods, global drinking motives and alcohol expectancies. Daily sadness was positively associated with not drinking due to having nobody with whom to drink but negatively associated with not drinking due to school work. Daily anxiety was negatively associated with not drinking due to lack of desire and positively associated with not drinking due to habit or having school or job responsibilities. At the person level, multiple RNDs were associated with both coping and conformity motives (but not social or enhancement motives), as well as positive (but not negative) alcohol expectancies. Results demonstrate the complexity of modelling mood-drinking contingencies proposed by motivational theories of alcohol use. Distinct moods may promote or inhibit drinking through various pathways, which could help explain the weak associations between daily mood and drinking level observed in previous studies. Measuring reasons both for and against drinking in micro-longitudinal studies (e.g. daily diaries) is recommended to better understand the processes underlying alcohol use and to inform future prevention efforts.

Studying the effectiveness of Group Therapy Based Life Enrichment and Enhancement Program on improvement of Therapeutic Indicates of Addiction in Dependent Men to Opiate

Abstract Background and aim: Despite significant advances in the field of detoxification and maintenance treatment, findings imply high rates of treatment failure and increase in the relapse even with the early success in detoxification. The purpose of this study was to examine the effectiveness of group therapy based life enrichment and enhancement program on improving of therapeutic indices of addiction in dependent men to opium. Material and methods: A quasi-experimental pretest-posttest design was used.The sample of the study consisted of 24 male substance abusers who were receiving methadone treatment in Iran Pak clinic , in Mashhad city. They were selected by convince method and randomly assigned in two experimental and control groups. Participants of experimental group attended in life enrichment and enhancement program for 5 sessions. Data were collected by 3 instruments : Personal Concerns Inventory, The Satisfaction with Life Scale and Craving and Temptation Scale which were completed by both groups before and after intervention. Data were analyzed by SPSS-18. Finding: Findings showed that the life enrichment and enhancement program significantly improved adaptive motivational structure score (P<0.01) and life satisfaction score (p<0.05) in intervention group. The LEEP also significantly decreased the craving and temptation scores in intervention group (P<0.05). Conclusion: Group therapy based Life enrichment and enhancement program can be an effective method in promotion of motivational structure, satisfaction with life and also reduction of temptation of drug abuse in men substance abusers who are under methadone treatment. Key words: Life Enrichment and Enhancement Program, Group therapy, Addiction, Opiate, The Satisfaction with Life, Temptation.
