RESUMO

Evidence suggests empathy deficits have a temporal relationship with substance use severity by late adolescence theorized to decrease use via recognition of social consequences. However, this has yet to be tested empirically along with differences in cognitive and affective empathy. Adolescents admitted to substance use treatment (n= 3,382) were followed through treatment and 12 months after treatment. Variable trajectories were fit using growth curve models; and cross-lagged effects of cognitive and affective empathy on response to social consequences of use were tested along with how response to social consequences affected the mean trajectory of substance use. Results indicate higher cognitive empathy predicted greater response to social consequences of use and response to these consequences at the end of treatment predicted a steeper decrease in substance use. This evidence highlights the importance of cognitive empathy for responding to social consequences of use for motivating less substance use in adolescents.

RESUMO

The complexity of executive function (EF) impairments in youth antisocial phenotypes of callous-unemotional (CU) traits and conduct problems (CP) challenge identifying phenotypic specific EF deficits. We can redress these challenges by (1) accounting for EF measurement error and (2) testing distinct functional brain properties accounting for differences in EF. Thus, we employed a latent modeling approach for EFs (inhibition, shifting, fluency, common EF) and extracted connection density from matching contemporary EF brain models with a sample of 112 adolescents (ages 13-17, 42% female). Path analysis indicated CU traits associated with lower inhibition. Inhibition network density positively associated with inhibition, but this association was strengthened by CU and attenuated by CP. Common EF associated with three-way interactions between density*CP by CU for the inhibition and shifting networks. This suggests those higher in CU require their brain to work harder for lower inhibition, whereas those higher in CP have difficulty engaging inhibitory brain responses. Additionally, those with CP interacting with CU show distinct brain patterns for a more general EF capacity. Importantly, modeling cross-network connection density in contemporary EF models to test EF involvement in core impairments in CU and CP may accelerate our understanding of EF in these phenotypes.

RESUMO

Callous-unemotional (CU) traits are characterized by a lack of prosocial emotions, which has been demonstrated with prosocial behavior paradigms. While shaping our understanding of prosocial behavior in youth with CU traits, most of this work relies on outcomes that don't reliably capture cognitive processes during prosocial behavior. Examining prosocial cognitive processes can cue researchers into cognitive mechanisms underlying core impairments of CU traits. Drift diffusion modeling is a valuable tool for elucidating more precise outcomes of latent cognitive processes during forced choice tasks such as drift rate (information accumulation toward a decision boundary) and threshold separation (amount of information considered) as well as metrics outside of the decision-making processing including bias (starting point in decision process) and non-decision time (cognitive processes outside of choice). In a sample of 87 adolescents (12-14, 49% female) we applied diffusion modeling to a prosocial behavior task in which participants either accepted or rejected trials where a real monetary value was given to them and taken away from a charity (self-serving trial) or money was given to a charity and taken from them (donation trial). Results revealed that CU traits associated with information accumulation toward accepting self-serving trials. Exploratory sex differences suggested males trended toward rejecting donation trials and females considered more information during self-serving trials. CU trait associations were independent of conduct problems. Results suggest a unique cognitive profile that are differentiated by sex at higher CU traits when making prosocial decisions involving knowledge accumulation toward self-serving decisions.

RESUMO

Objective: To investigate the association of cannabis use with major depression and suicidal behavior in adolescence. Method: Data are from the National Comorbidity Survey-Adolescent Supplement N=10,123, a nationally representative survey of adolescents aged 13 to 18 years. Weighted logistic regression and ordinal regression analyses of major depression and suicidal behavior outcomes were conducted on cannabis variables, incorporating sociodemographic characteristics. Results: Adolescents with lifetime cannabis use have 2.07 times higher odds of mild/moderate (adjusted odds ratio [aOR]; 95% CI=1.69, 2.53) and 3.32 times higher odds of severe major depressive disorder (MDD; aOR; 95% CI=2.31, 4.75). Cannabis use (aOR 6.90, 95% CI=4.67,10.19), mild/moderate MDD (aOR 4.10, 95% CI=2.82, 5.98), and severe MDD (aOR 13.97, 95% CI = 7.59, 25.70) were associated with higher odds of suicide attempt. Past 12-month cannabis use (aOR 3.70, 95% CI = 2.16, 6.32), mild/moderate major depressive episodes (MDE) (aOR 7.85, 95% CI=3.59, 17.17), and severe MDE (aOR 36.36, 95% CI=13.68,96.64) were associated with higher odds of suicide attempt. The frequency of past 12-month cannabis use was associated with higher odds of suicide attempt and with MDE severity, with higher odds among individuals who use cannabis 3 or more days than among individuals who use cannabis less frequently, suggesting a dose effect. Among cannabis users, older age of onset of cannabis use was associated with lower odds of suicidal behaviors. Conclusion: Cannabis use is associated with higher odds of depression and depression severity in adolescence. Furthermore, depression and cannabis use are independently associated with higher odds of suicide attempt.

RESUMO

Empathy impairments are an important part of a broader affective impairments defining the youth antisocial phenotype callous-unemotional (CU) traits and the DSM-5 low prosocial emotion (LPE) specifier. While functional connectivity underlying empathy and CU traits have been well studied, less is known about what functional connections underly differences in empathy amongst adolescents qualifying for the LPE specifier. Such information can provide mechanistic distinctions for this clinically relevant specifier. The present study uses connectome-based predictive modeling that uses whole-brain resting-state functional connectivity data to predict cognitive and affective empathy for those meeting the LPE specifier (n = 29) and those that do not (n = 57). Additionally, we tested if models of empathy generalized between groups as well as density differences for each model of empathy between groups. Results indicate the LPE group had lower cognitive and affective empathy as well as higher CU traits and conduct problems. Negative and positive models were identified for affective empathy for both groups, but only the negative model for the LPE and positive model for the normative group reliably predicted cognitive empathy. Models predicting empathy did not generalize between groups. Density differences within the default mode, salience, executive control, limbic, and cerebellar networks were found as well as between the executive control, salience, and default mode networks. And, importantly, connections between the executive control and default mode networks characterized empathy differences the LPE group such that more positive connections characterized cognitive differences and less negative connections characterized affective differences. These findings indicate neural differences in empathy for those meeting LPE criteria that may explain decrements in empathy amongst these youth. These findings support theoretical accounts of empathy decrements in the LPE clinical specifier and extend them to identify specific circuits accounting for variation in empathy impairments. The identified negative models help understand what connections inhibit empathy whereas the positive models reveal what brain patterns are being used to support empathy in those with the LPE specifier. LPE differences from the normative group and could be an appropriate biomarker for predicting CU trait severity. Replication and validation using other large datasets are important next steps.

RESUMO

Introduction: Callous-unemotional (CU) traits are a youth antisocial phenotype hypothesized to be a result of differences in the integration of multiple brain systems. However, mechanistic insights into these brain systems are a continued challenge. Where prior work describes activation and connectivity, new mechanistic insights into the brain's functional connectome can be derived by removing nodes and quantifying changes in network properties (hereafter referred to as computational lesioning) to characterize connectome resilience and vulnerability. Methods: Here, we study the resilience of connectome integration in CU traits by estimating changes in efficiency after computationally lesioning individual-level connectomes. From resting-state data of 86 participants (48% female, age 14.52 ± 1.31) drawn from the Nathan Kline institute's Rockland study, individual-level connectomes were estimated using graphical lasso. Computational lesioning was conducted both sequentially and by targeting global and local hubs. Elastic net regression was applied to determine how these changes explained variance in CU traits. Follow-up analyses characterized modeled node hubs, examined moderation, determined impact of targeting, and decoded the brain mask by comparing regions to meta-analytic maps. Results: Elastic net regression revealed that computational lesioning of 23 nodes, network modularity, and Tanner stage explained variance in CU traits. Hub assignment of selected hubs differed at higher CU traits. No evidence for moderation between simulated lesioning and CU traits was found. Targeting global hubs increased efficiency and targeting local hubs had no effect at higher CU traits. Identified brain mask meta-analytically associated with more emotion and cognitive terms. Although reliable patterns were found across participants, adolescent brains were heterogeneous even for those with a similar CU traits score. Conclusion: Adolescent brain response to simulated lesioning revealed a pattern of connectome resiliency and vulnerability that explains variance in CU traits, which can aid prediction of youth at greater risk for higher CU traits.

RESUMO

Affective theory of mind (aToM) impairments associated with the youth antisocial phenotype callous-unemotional (CU) traits predict antisocial behaviour above CU traits alone. Importantly, CU traits associate with decrements in complex but not basic aToM. aToM is modulated by cognitive control and CU traits associate with cognitive control impairments; thus, cognitive control is a plausible mechanism underlying aToM impairments in CU traits. Because cognitive control is dependent on the availability of cognitive resources, youth with CU traits may have difficulty with allocating cognitive resources under greater demands that impact complex aToM. To test this, 81 participants (ages 12-14, Female = 51.8%, Male = 48.2%) were recruited to complete a behavioural paradigm that involved an initial aToM task with complex and basic emotions followed by placing additional demands on cognitive control and a final repeat of the same aToM task. Results indicate adolescents higher in CU traits had intact basic aToM but less accuracy in complex aToM that worsened after taxing cognitive control; and this load only required a short duration to account for ToM decrements (200 ms [range 150-1600 ms]). These results demonstrate CU traits association with cognitive control limitations that impact complex aToM. This may partially explain antisocial behaviour associated with CU traits.

RESUMO

Background: Adolescence is a common time for experimentation with substance use and the emergence of sex differences in substance use patterns. Although similar in early adolescence, male and female substance use patterns historically diverge by young adulthood, with males using more substances than females. We aim to add to current literature by utilizing a nationally representative sample, assessing a broad range of substances used, and focusing on a sentinel period during which sex differences emerge. We hypothesized that certain sex-specific substance use patterns emerge in adolescence. Methods: Data are from the 2019 Youth Risk Behavior Survey (n = 13,677), a nationally representative sample of high school students. Weighted logistic analyses of covariance adjusting for race/ethnicity evaluated males' and females' substance use (14 outcomes) by age category. Results: Among all adolescents, more males reported illicit substance use and cigarette smoking than females, whereas more females reported prescription opioid misuse, synthetic cannabis use, recent alcohol use, and binge drinking. Divergence between male and female use usually occurred at 18+ years. Odds of using most illicit substances were significantly greater among males than females at age 18+ years (aORs 1.7-4.47). Among 18+ year-olds, males and females did not differ in electronic vapor product use, alcohol use, binge drinking, cannabis use, synthetic cannabis use, cigarette smoking, or prescription opioid misuse. Conclusions: Sex differences in adolescent use of most but not all substances emerge by age 18+ years. Sex-specific patterns of adolescent substance use may inform specific prevention efforts and identify peak ages for intervention.

RESUMO

BACKGROUND: Prosocial behavior is negatively associated with psychopathic traits and paradigms which measure prosocial behavior in the laboratory may be useful in better understanding moderators of this association. METHODS: We revised a previously validated game of prosocial behavior by including a new trial type (i.e., trials where the participant will lose money and the charity will gain money). This version of the game was administered online and participants were randomized to group (exposed to a control stimulus video or a video used to elicit moral elevation, i.e. a positive response to witnessing another's act of kindness). We used repeated game administration to test whether a moral elevation stimulus affected game behavior and moderated the negative association between psychopathic traits and prosocial behavior. RESULTS: Prosocial behavior on the new trial types added in this revised game correlated strongly with prosocial behavior on the old trial type (i.e., trials where the participant will gain money and the charity will lose money; r = 0.71; p-value<0.001; n = 485). Graphing trial acceptance rates by trial characteristics demonstrated expected patterns of behavior. Number of prosocial choices on the game correlated with psychopathic trait score (Levenson Factor 1 score; r = -0.52; p-value<0.001). Game repetition with a control stimulus in between runs, supported high immediate test-retest reliability of overall game behavior. Exposure to the moral elevation stimulus in between runs did not affect game behavior nor moderate the association between psychopathic traits and prosocial behavior. CONCLUSIONS: Choices on this revised game of prosocial behavior, which can be administered online, are associated with psychopathic traits scores. The game appears to have high immediate test-retest reliability. Exposure to the moral elevation stimulus did not affect prosocial behavior or impact the relationship between psychopathic trait scores and prosocial behavior. Future research should continue to test potential moderators of this relationship. Limitations of the current study are discussed.

RESUMO

Callous-Unemotional (CU) traits are often associated with impairments in perspective taking and cognitive control (regulating goal directed behavior); and adolescents with CU traits demonstrate aberrant brain activation/connectivity in areas underlying these processes. Together cognitive control and perspective taking are thought to link mechanistically to explain CU traits. Because increased cognitive control demands modulate perspective taking ability among both typically developing samples and individuals with elevated CU traits, understanding the neurophysiological substrates of these constructs could inform efforts to alleviate societal costs of antisocial behavior. The present study uses GIMME to examine the heterogenous functional brain properties (i.e., connection density, node centrality) underlying cognitive control's influence on perspective taking among adolescents on a CU trait continuum. Results reveal that cognitive control had a negative indirect association with CU traits via perspective taking; and brain connectivity indirectly associated with lower CU traits - specifically the social network via perspective taking and conflict network via cognitive control. Additionally, less negative connection density between the social and conflict networks was directly associated with higher CU traits. Our results support the growing literature on cognitive control's influence on socio-cognitive functioning in CU traits and extends that work by identifying underlying functional brain properties.

RESUMO

Suicide, a common cause of death in adolescents, is linked to internalizing and externalizing symptoms. These associations are pronounced amongst adolescents who use substances. But these relationships are complex. For example, sex differences are present in association with internalizing/externalizing symptoms as well as differences in suicidality. A rarely explored factor that may account for this complexity as a moderator is callous-unemotional traits. The present study examines associations of internalizing and externalizing in relation to suicidality in the context of callous-unemotional traits amongst adolescents in substance use treatment. Additionally, sex differences were explored. A sample of 317 adolescents (13-18; 16.05 ± 1.22) in treatment for substance use completed measures for internalizing, externalizing, and suicidal symptoms. The main result suggested the presence of callous-unemotional (CU) traits attenuated the positive association between internalizing and a latent suicidality factor. This novel result contextualizes the association between transdiagnostic symptoms and suicidality. Assessing CU traits in the presence of internalizing symptoms may be an important component of understanding suicide risk amongst adolescents in treatment for substance use.

RESUMO

Callous-unemotional traits (CU) associates with impairments in emotional responsivity. However, there is less evidence on associations with specific emotions and sex differences utilizing both self and other oriented emotional stimuli. Given that the nuance of associations with specific emotions (including sex effects) is critical for understanding core impairments of this antisocial phenotype, the current study employed a behavioral paradigm with both self and other emotional stimuli for specific emotions (happy, sad, anger, fear, neutral) with a sample of male and female early adolescents (females = 51%, age = 12.86 ± 0.75). We examined accuracy and reaction times on this task, along with moderating effects of sex, in relation to CU traits. Results indicate CU traits associated with overall self-emotions negatively and sex moderated CU traits negative association with recognizing others overall emotions. CU traits negatively associated with accurate identification of both self and other emotions (happy, sad, and fear). Sex moderated all other emotion identification but only sad emotions for self. No reaction time differences were found. These findings evidence important nuance in CU traits and sex effects with identifying self and other emotions. Results have important implications for clinical understanding of sex differences in CU traits that require further consideration.

RESUMO

Callous-unemotional (CU) traits in adolescents are a dimensional construct involving a symptom subset of empathy impairments amongst broader affective deficits. Higher CU trait scores associate with less cognitive and affective empathy; and brain regions linked with cognitive and affective empathy show aberrant function in those with CU traits. How CU traits impact the relationship between brain function and both cognitive and affective empathy in adolescents is less clear. Here we examine how functional properties of networks that support cognitive and affective empathy is moderated by CU traits. Eighty-four adolescents underwent resting-state fMRI scanning and completed self-reports for empathy (Interpersonal Reactivity Index) and CU traits (Inventory of Callous-Unemotional Traits). Analysis revealed that CU traits moderate the association between affective empathy and connectivity between the default mode-frontoparietal networks. Weaker between default mode-frontoparietal anticorrelation negatively associated with affective empathy at low to moderate CU traits. Those highest in CU traits had the lowest affective empathy; and negative associations for those highest in CU traits were insignificant as default mode-frontoparietal anticorrelation weakened. Our results indicate that functional properties of networks that support affective empathy is different at varying levels of CU traits. This novel finding demonstrates that CU traits presence changes the relationship between the brain and empathy.

RESUMO

BACKGROUND: Callous-unemotional (CU) traits, a youth antisocial phenotype, are hypothesized to associate with aberrant connectivity (dis-integration) across the salience (SAL), default mode (DMN), and frontoparietal (FPN) networks. However, CU traits have a heterogeneous presentation and previous research has not modeled individual heterogeneity in resting-state connectivity amongst adolescents with CU traits. The present study models individual-specific network maps and examines topological features of individual and subgroup maps in relation to CU traits. METHODS: Participants aged 13-17 (n = 84, male = 55%, female = 45%) completed resting-state functional connectivity and the inventory of callous-unemotional traits as part of the Nathan Klein Rockland study. A sparse network approach (GIMME) was used to derive individual-level and subgroup maps of all participants. We then examined heterogeneous network features, including positive and negative connection density, associated with CU traits. RESULTS: Higher rates of CU traits increased probability of inclusion in one subgroup, which had the highest mean level of CU traits. Analysis of network features reveals less density (positive and negative) within the FPN and greater density between DMN-FPN associated with CU traits. DISCUSSION: Findings indicate heterogeneous person-specific connections and some subgroup connections amongst adolescents associate with CU traits. Higher CU traits associate with lower density in the FPN, which has been associated with attention and inhibition, and higher density between the DMN-FPN, which have been linked with cognitive control, social working memory, and empathy. Our findings suggest less efficiency in FPN function which, when considered mechanistically, could result in difficulty suppressing DMN when task positive networks are engaged. This is an area for further exploration but could explain cognitive and socio-affective impairments in CU traits.

RESUMO

OBJECTIVES: Misuse of opioid medications (ie, using opioids differently than how a doctor prescribed the medication) is common among US adolescents and associated with preventable health consequences (eg, severe respiratory depression, seizures, heart failure, and death).1 New guidelines and recommendations have made providers more attuned to overprescribing and more vigilant about screening for opioid misuse.2 We hypothesized that youth who misused prescription opioids were more likely to report engaging in a broad range of other risky behaviors. METHODS: We used the Centers for Disease Control and Prevention's 2017 Youth Risk Behavior Surveillance Survey (n = 14 765), a cross-sectional, nationally representative survey of high school students. Students were sampled by using a 3-stage random cluster design. We conducted weighted logistic regressions to determine the strength of the association between our independent variable, ever misusing prescription opioids, and 22 dependent variables in the following categories: risky driving behaviors (4 variables), violent behaviors (3 variables), risky sexual behaviors (4 variables), substance use (10 variables), and suicide attempt (1 variable). RESULTS: In 2017, 14% of US adolescents reported ever misusing opioids. Those who misused prescription opioids were significantly more likely to have engaged in all 22 risky behaviors (adjusted odds ratios ranged from 2.0 to 22.3; P < .0001 for all tests) compared with other adolescents. CONCLUSIONS: Adolescents reporting ever misusing prescription opioids were more likely to have engaged in a broad range of risky behaviors. Health care providers screening for prescription opioid misuse may be ideally positioned to identify these high-risk youth and initiate early interventions.

RESUMO

OBJECTIVES: Marijuana's evolving legality may change marijuana use patterns in adults. Co-use of marijuana and tobacco are strongly associated, and populations with mental health disorders are disproportionately likely to use either substance, but neither association has been assessed in the context of legal recreational marijuana. We assessed the associations of tobacco smoking with marijuana use and with mental health disorders in Colorado in 2015. METHODS: Data came from a population-based survey of adults (n = 8023). Multiple logistic regressions were used with current tobacco smoking as the primary outcome. Past 30-day marijuana use and mental health status were the independent variables of interest. Covariates included age, sex, ethnicity, poverty level, and education. RESULTS: Adults who used marijuana in the past 30 days had 3.4 (95% confidence interval [CI] 2.7, 4.2) greater odds of currently smoking tobacco compared to adults who had not recently used marijuana, after adjusting for sociodemographic and economic factors. A mental health disorder was independently associated with tobacco smoking (adjusted odds ratio [OR] 1.7, 95% CI 1.4, 2.1). Prevalence of co-use among adults self-reporting a mental health disorder was significantly higher compared those without a mental health disorder (11.1% vs 4.3%; P < 0.0001). CONCLUSIONS: This study examined the associations between mental health, marijuana use, and tobacco smoking after the legalization of recreational marijuana in Colorado. Adults using marijuana and/or self-reporting a mental health disorder were more likely to smoke tobacco and should be targeted for cessation interventions.

RESUMO

When presented with decisions that require simultaneously weighing self-benefit and other harm, adolescents with callous-unemotional traits compared with controls engage in less Costly Helping (i.e., giving up a benefit to protect a beneficent other). Young adults completed questionnaires, played an online-administered game of Costly Helping, and viewed an Elevation stimulus video (when witnessing another's act of virtue, individuals may experience a positive or elevating response). Subjects were assigned to one of four study arms, which varied the order of presentation. Higher levels of Factor 1 (callousness) psychopathic trait scale scores (assessed using the Levenson Self-Report Psychopathy Scale) were associated with significantly less Costly Helping. Elevation associated positively with Costly Helping behaviors and negatively with psychopathic traits. Introducing Elevation as an independent variable in regression analyses attenuated the relationship between psychopathic traits and Costly Helping, suggesting mediation. Those viewing the Elevation stimulus video prior to playing the game, as opposed to after, trended toward more Costly Helping by taking less money for themselves ($3.28vs. $3.72). Results support that this simple game provides meaningful behavioral data associated with psychopathic traits. Differences in Elevation may, in part, explain the observed differences in prosocial behavior in those with high psychopathic traits.

RESUMO

PURPOSE: The opioid epidemic in the United States is an ongoing public health concern. Health care institutions use standardized patient satisfaction surveys to assess the patient experience and some offer incentives to their providers based on the results. We hypothesized that providers who report being incentivized based on patient satisfaction surveys are more likely to report an impact of such surveys on their opioid prescribing practices. METHODS: We developed a 23-item survey instrument to assess the self-perceived impact of patient satisfaction surveys on opioid prescribing practices in primary care and the potential impact of institutional incentives. The survey was emailed to all 1404 members of the Colorado Academy of Family Physicians. RESULTS: The response rate to the online survey was 10.4% (n = 146). Clinical indications for which responders prescribe opioids included acute pain (93%), cancer pain (85%), and chronic nonmalignant pain (72%). Among physicians using patient satisfaction surveys, incentivized physicians reported at least a slight impact on opioid prescribing 3 times more often than physicians who were not incentivized (36% vs 12%, P = .004). CONCLUSIONS: Efforts to improve patient satisfaction may have potentially untoward effects on providers' opioid prescribing behaviors. Our results suggest a need to further study the impact of provider incentive plans that are based on patient satisfaction scores.

RESUMO

OBJECTIVE: To examine if a substance use disorder (SUD), especially cannabis use disorder in adolescence, predicts future medical cannabis card status among high-risk youth. METHODS: Data collection occurred in Denver and San Diego. We recruited adolescents, with or at high risk for SUD and conduct problems (hereafter probands) and their siblings (n=654). Baseline (Wave 1) assessments took place between 1999 and 2008, and follow-up (Wave 2) took place between 2010 and 2013. In initial bivariate analyses, we examined whether baseline DSM-IV cannabis abuse/dependence (along with other potential predictors) was associated with possessing a medical cannabis card in young adulthood (Wave 2). Significant predictors were then included in a multiple binomial regression. Self-reported general physical health was also evaluated at both time points. Finally, within Wave 2, we tested whether card status was associated with concurrent substance dependence. RESULTS: About 16% of the sample self-reported having a medical cannabis card at follow-up. Though bivariate analyses demonstrated that multiple predictors were significantly associated with Wave 2 card status, in our multiple binomial regression only cannabis abuse/dependence and male sex remained significant. At Wave 2, those with a medical cannabis card were significantly more likely to endorse criteria for concurrent cannabis dependence. There was no significant difference in self-reported general physical health. CONCLUSIONS: Cannabis abuse/dependence and male sex positively predicted future medical cannabis card holder status among a sample of high risk adolescents. Physicians conducting evaluations for medical cannabis cards should carefully evaluate and consider past and concurrent cannabis addiction.

RESUMO

Behavioral approach, defined as behavior directed toward a reward or novel stimulus, when elevated, may increase one's vulnerability to substance use disorder. Behavioral approach has been associated with relatively greater left compared to right frontal activity; behavioral inhibition may be associated with relatively greater right compared to left frontal brain activity. We hypothesized that substance dependent individuals (SDI) would have higher behavioral approach than controls and greater prefrontal cortical activity during decision-making involving reward. We hypothesized that behavioral approach would correlate with left frontal activity during decision-making and that the correlation would be stronger in SDI than controls. 31 SDI and 21 controls completed the Behavioral Inhibition System/Behavioral Approach System (BIS/BAS) scales and performed a decision-making task during fMRI. Orbitofrontal (OFC) and dorsolateral prefrontal activity were correlated with BIS and BAS scores. Compared to controls, SDI had higher BAS Fun Seeking scores (p<0.001) and worse decision-making performance (p=0.004). BAS Fun Seeking correlated with left OFC activity during decision-making across group (r=0.444, p<0.003). The correlation did not differ by group. There was no correlation between BIS and right frontal activity. Left OFC may play a role in reward-related decision-making in substance use disorder especially in individuals with high behavioral approach.
