ABSTRACT

Background: Few studies have investigated changes in brain structure and function associated with recovery from cocaine use disorder (CUD), and fewer still have identified brain changes associated with specific CUD treatments, which could inform treatment development and optimization. Methods: In this longitudinal study, T1-weighted magnetic resonance imaging scans were acquired from 41 methadone-maintained individuals with CUD (15 women) at the beginning of and after 12 weeks of outpatient treatment. As part of a larger randomized controlled trial, these participants were randomly assigned to receive (or not) computer-based training for cognitive behavioral therapy (CBT4CBT), and galantamine (or placebo). Results: Irrespective of treatment condition, whole-brain voxel-based morphometry analyses revealed a significant decrease in right caudate body, bilateral cerebellum, and right middle temporal gyrus gray matter volume (GMV) at post-treatment relative to the start of treatment. Subsequent region of interest analyses found that greater reductions in right caudate and bilateral cerebellar GMV were associated with higher relative and absolute levels of cocaine use during treatment, respectively. Participants who completed more CBT4CBT modules had a greater reduction in right middle temporal gyrus GMV. Conclusions: These results extend previous findings regarding changes in caudate and cerebellar GMV as a function of cocaine use and provide the first evidence of a change in brain structure as a function of engagement in digital CBT for addiction. These data suggest a novel potential mechanism underlying how CBT4CBT and CBT more broadly may exert therapeutic effects on substance-use-related behaviors through brain regions implicated in semantic knowledge.

ABSTRACT

Bullying, traditional or cyber, among adolescents, is a public health concern. In this study, we explored frequencies and correlates of different forms of bullying among Connecticut high-school students. Youth Risk Behavior Survey data from 2019 from Connecticut adolescents (N = 1814) were used. χ2 tests and survey-weighted logistic regressions examined relationships between bullying subgroups (in-school traditional bullying (ISTB) only, cyberbullying only, and both) and mental concerns, risk behaviors, academic performance, physical health, and receipt of social support, with the logistic regressions adjusted for demographics. The past-12-month frequency of having experienced only cyberbullying was 5.6%, only ISTB was 9.1%, and both forms was 8.7%. Between-group differences were observed by bullying status in terms of sex and race/ethnicity. In adjusted models, bullying status was associated with suicide attempts, suicidal ideation, self-harm, depression/dysphoria, mental health, use of alcohol, marijuana, injection drugs, tobacco, and e-vapor, gambling, driving under influence of alcohol, high-risk sexual behavior, physical fights, weapon-carrying, injuries/threats at school, feeling unsafe at school, dating violence, obesity, poor general health, insecure housing, less perceived family support, and poor academic performance. People experiencing both types of bullying were typically more likely to report adverse measures. High-school students commonly report bullying. The findings that both forms (traditional and cyber) were more robustly linked to negative experiences highlight the need for examining further relationships between types and patterns of bullying and mental health and functioning. Better understanding may help improve preventive anti-bullying interventions.

ABSTRACT

Mothers who use substances during pregnancy and postpartum may have altered maternal behavior towards their infants, which can have negative consequences on infant social-emotional development. Since maternal substance use has been associated with difficulties in recognizing and responding to infant emotional expressions, investigating mothers' subjective responses to emotional infant stimuli may provide insight into the neural and psychological processes underlying these differences in maternal behavior. In this study, 39 mothers who used substances during the perinatal period and 42 mothers who did not underwent functional magnetic resonance imaging while viewing infant faces and hearing infant cries. Afterwards, they rated the emotional intensity they thought each infant felt ('think'-rating), and how intensely they felt in response to each infant stimulus ('feel'-rating). Mothers who used substances had lower 'feel'-ratings of infant stimuli compared to mothers who did not. Brain regions implicated in affective processing (e.g., insula, inferior frontal gyrus) were less active in response to infant stimuli, and activity in these brain regions statistically predicted maternal substance-use status. Interestingly, 'think'-ratings and activation in brain regions related to cognitive processing (e.g., medial prefrontal cortex) were comparable between the two groups of mothers. Taken together, these results suggest specific neural and psychological processes related to emotional responsivity to infant stimuli may reflect differences in maternal affective processing and may contribute to differences in maternal behavior in mothers who use substances compared to mothers who do not. The findings suggest potential neural targets for increasing maternal emotional responsivity and improving child outcomes.

ABSTRACT

Background: Exposure to substances in utero may have significant early-life consequences. Less is known about the effects in emerging adulthood, particularly regarding patterns of substance use and related characteristics.Objectives: In this study, we recruited emerging adults, followed since birth, who had been prenatally exposed, or not, to cocaine. Individuals reported on their cannabis, alcohol, and tobacco use, and measures of impulsivity, anhedonia, emotional regulation, and mental health were obtained. Comparisons were made between emerging adults with prenatal cocaine exposure and those without. Correlations were performed between psychological measures and substance use, and regression analyses were conducted to determine potential pathways by which such measures may relate to prenatal exposure or substance use.Results: Individuals with prenatal cocaine exposure (vs. those without) used cannabis at younger ages, reported greater cannabis-use severity, and demonstrated higher impulsivity, state anxiety, and alexithymia. Earlier age of onset of cannabis use was associated with higher impulsivity, state anxiety, alexithymia, and social and physical anhedonia. Cannabis-use age-of-onset mediated the relationship between prenatal cocaine-exposure status and state anxiety and between prenatal cocaine-exposure status and cannabis-use severity in emerging adulthood but not relationships between prenatal cocaine-exposure status and impulsivity or alexithymia in emerging adulthood. Findings suggest that adults with prenatal cocaine exposure may use cannabis at younger ages, which may relate to increased anxiety and more severe use.Conclusions: These findings suggest both mechanisms and possible intervention targets to improve mental health in emerging adults with prenatal cocaine exposure.

ABSTRACT

Background and aims: Gambling in adolescents is a public health concern. This study sought to examine patterns of gambling among Connecticut high-school students using seven representative samples covering a 12-year period. Methods: Data were analyzed from N = 14,401 participants in cross-sectional surveys conducted every two years based on random sampling from schools in the state of Connecticut. Anonymous self-completed questionnaires included socio-demographic data, current substance use, social support, and traumatic experiences at school. Chi-square tests were used to compare socio-demographic characteristics between gambling and non-gambling groups. Logistic regressions were used to assess changes in the prevalence of gambling over time and effects of potential risk factors on the prevalence, adjusted for age, sex, and race. Results: Overall, the prevalence of gambling largely decreased from 2007 to 2019, although the pattern was not linear. After steadily declining from 2007 to 2017, 2019 was associated with increased rates of gambling participation. Consistent statistical predictors of gambling were male gender, older age, alcohol and marijuana use, higher levels of traumatic experiences at school, depression, and low levels of social support. Discussion and conclusion: Among adolescents, older males may be particularly vulnerable to gambling that relates importantly to substance use, trauma, affective concerns, and poor support. Although gambling participation appears to have declined, the recent increase in 2019 that coincides with increased sports gambling advertisements, media coverage and availability warrants further study. Our findings suggest the importance of developing school-based social support programs that may help reduce adolescent gambling.

ABSTRACT

OBJECTIVE: Disinhibitory behavior during childhood and adolescence has been frequently shown to amplify the risk for substance use disorder (SUD) in adulthood. This prospective study examined the hypothesis that poor communication with parents and association with deviant peers comprise an SUD-promoting environtype which catalyzes transition of disinhibitory behavior toward SUD. METHOD: Male (N = 499) and female (N = 195) youths were tracked from 10 to 12 to 30 years of age. Path analysis evaluated the patterning of disinhibitory behavior and social environment during childhood on substance use during adolescence, and antisocial personality without co-occurring SUD in early adulthood and subsequently substance use disorder (SUD). RESULTS: Disinhibitory behavior (SUD vulnerability) in childhood predicts antisociality without SUD (age 22) that segues to SUD (age 23-30) whereas the environtype (parents and peers) predicts substance use during adolescence which predicts antisocial personality leading to SUD. Antisociality without SUD in early adulthood mediates the association of substance use during adolescence and SUD. CONCLUSION: Disinhibitory behavior and deviance-promoting social environment conjointly promote development of SUD via deviant socialization.

ABSTRACT

BACKGROUND: Coronavirus disease-2019 (COVID-19) has had negative physical and mental impacts on people globally. The current study examined general psychiatric symptoms (fear, anxiety, depression, and insomnia) and loneliness, and their interrelationships and correlates among Bangladeshi individuals approximately 1 year after the onset of the COVID-19 outbreak. METHODS: An internet-based cross-sectional survey was conducted among 1004 Bangladeshi people (51.8% male; mean age: 25.41 ± 7.80; age range: 18-60 years). Data were collected using a semi-structured e-questionnaire including informed consent, socio-demographics, lifestyle measures, and psychometric tools assessing loneliness, anxiety, depression, insomnia, and fear of COVID-19. RESULTS: Sizeable participants screened positive for loneliness (63.5%), anxiety (26.3%), depression (46.4%), and insomnia (50.7%). Considerable numbers of respondents also reported fear of COVID-19. In hierarchical regression analyses, loneliness, anxiety, depression, insomnia, and fear of COVID-19 were associated with socio-demographic and lifestyle factors. Loneliness, anxiety, depression, insomnia, and fear of COVID-19 were positively correlated with each other (p < 0.001). In exploratory path analyses, anxiety, depression, and insomnia mediated the relationship between loneliness and fear of COVID-19. CONCLUSIONS: The findings indicate that many people in Bangladesh have experienced psychiatric concerns approximately 1 year after the onset of the COVID-19 outbreak. Investigation into empirically supported interventions and their implementation is needed.

ABSTRACT

Problematic video gaming (PVG) and problematic shopping (PS) are addictive behaviors prevalent in adolescents, characterized by positive and negative reinforcement, and associated with psychosocial impairment. This study examined how PS and PVG relate in adolescents. It also examined how PS interacts with PVG in relation to health/functioning measures. Survey data from 3,657 Connecticut high-school students were evaluated. Chi-square analyses and logistic regression models were used to assess relationships between PS and measures of PVG. Interaction analyses measured effects of PS on relationships between PVG and health/functioning measures. Relative to adolescents without PS, those with PS had 8.79-fold higher odds of exhibiting PVG and were more likely to endorse gaming to relieve anxiety and impairment due to gaming. Interaction analyses revealed that in adolescents with PS, the relationships between PVG and aggressive behaviors, including fighting, serious fighting leading to physical injury, and weapon-carrying, were stronger than in adolescents without PS. PS strongly relates to PVG, and among youth reporting PS, there are stronger associations between PVG and aggressive behaviors. Prevention efforts for adolescents should consider the co-occurrence of PS and PVG. PS and PVG may be linked by negative reinforcement and propensities for aggressive and addictive behaviors, suggesting that further research should explore possible interventions targeting stress management and maladaptive coping.

ABSTRACT

The desire to escape from pressures/anxiety represents an important motivation for problematic engagement with short-term rewarding behaviors that could contribute to the development of recognized and candidate behavioral addictions, including problematic shopping, a prevalent condition among youth in the U.S.A. characterized by excessive shopping cognitions/behaviors that lead to distress/impairment. However, to date, the specific correlates of shopping to relieve anxiety or tension have yet to be evaluated. We aimed at addressing this gap by analyzing data (N = 2556) from a high-school survey from Connecticut in an exploratory fashion. Adolescents who acknowledged experiencing a growing tension or anxiety that could only be relieved by shopping were classified as having negative-reinforcement shopping and compared to the remaining students. Data were analyzed in chi-square and logistic regression models to examine negative-reinforcement shopping in relation to socio-demographics, health correlates, gambling-related perceptions/attitudes, and problem-gambling severity/gambling behaviors. Negative-reinforcement shopping was more frequent in female and Hispanic students, was linked to more permissive gambling attitudes and at-risk/problematic gambling, and was associated with the use of alcohol, tobacco, marijuana, and other drugs, dysphoria/depression, and weapon-carrying and physical fighting. Taken together, these findings highlight adverse measures of health and functioning linked to negative-reinforcement shopping that may be particularly relevant to girls and Hispanic youth. Additional efforts to prevent negative outcomes are warranted.

ABSTRACT

Gambling and anxiety are major public health concerns in adolescents and have been linked to emotion dysregulation and mood-modulating behaviors. While previous studies have shown links between positively reinforcing excitement-motivated gambling, health and functioning measures, and gambling perceptions and behavioral correlates in adolescents, few studies have examined such relationships relative to negatively reinforcing anxiety-motivated gambling (AMG). This study systematically examined relationships between adolescents reporting gambling to relieve anxiety (compared to those who gambled but did not report AMG) and measures of health/functioning and gambling-related measures. Participants included 1,856 Connecticut high-school students. Chi-square and logistic regression models were conducted. AMG was reported by 6.41% of the sample and was associated with identifying with a minority group (Black, Asian-American, Hispanic), at-risk/problem gambling, more permissive attitudes towards gambling, and higher odds of heavy alcohol, tobacco and other drug use, and violence-related measures. Adolescents with AMG were more likely to report non-strategic gambling, and gambling to escape/relieve dysphoria and due to feeling pressure. Additional between-group differences were found for gambling types, locations, motivations, and partners. Together, AMG may represent a mood-modulating behavior indicative of multiple problematic concerns, suggesting that emotional dysregulation may be an important factor in understanding the relationship between anxiety, problem gambling, and risky behaviors in youth. Additionally, the negative reinforcing motivations to gamble to relieve anxiety may be relevant particularly to adolescents from underrepresented minority racial/ethnic groups, and the specific factors underlying this relationship warrant further investigation.

ABSTRACT

Characterizing variations in the timing of alcohol, cigarette, and cannabis use onset both among and between Black and White youth can inform targeted prevention. The current study aimed to capture cross-substance initiation patterns in Black and White girls and characterize these patterns with respect to substance use related socioeconomic, neighborhood, family, community, and individual level factors. Data were drawn from interviews conducted at ages 8 through 17 in an urban sample of girls (n = 2172; 56.86% Black, 43.14% White). Discrete-time multiple event process survival mixture modeling was used to identify patterns (i.e., classes) representing timing of alcohol, cigarette, and cannabis use initiation, separately by race. Class characteristics were compared using multinomial logistic regression. Among both Black and White girls, four classes, including abstainer and cross-substance early onset classes, emerged. Two classes characterized by mid-adolescence onset (Black girls) and variation in onset by substance (White girls) were also observed. Class differences centered around cannabis for Black girls (e.g., preceding or following cigarette use) and alcohol for White girls (e.g., (in)consistency over time in greater likelihood of initiation relative to cigarette and cannabis use). Several factors distinguishing the classes were common across race (e.g., externalizing behaviors, friends' cannabis use); some were specific to Black girls (e.g., intentions to smoke cigarettes) or White girls (e.g., primary caregiver problem drinking). Findings underscore the need to recognize a more complex picture than a high-risk/low-risk dichotomy for substance use initiation and to attend to nuanced differences in markers of risky onset pathways between Black and White girls.

ABSTRACT

Problematic use of the internet (PUI) and self-injurious behaviors (SIB) associate in adolescents and both relate to impulsivity. However, studies have not examined whether difficulties in impulse control are shared in adolescents with PUI and SIB, and how PUI relates to SIB frequency and impairment. Here, exploratory factor analysis was performed on a PUI questionnaire based on the Minnesota Impulse Disorder Interview, using survey data from 2,912 Connecticut high-school students. Regression analyses evaluated relationships between PUI factor scores and correlates of SIB. Moderation analyses examined impulsivity and sensation-seeking in relationship to PUI factors and SIB. Two PUI factors were extracted. The first PUI factor was associated with lifetime SIB, frequency, severity, urges, rising tension, and self-perceived problems with SIB. The second factor was associated with lifetime SIB and attempts to reduce SIB. Impulsivity and sensation-seeking associated with PUI factors and SIB, but did not moderate relationships between PUI and SIB. Findings suggest that PUI and SIB are related by difficulties in impulse control, and poor control over internet use is associated with more impairing SIB in adolescents who self-injure. Further research should investigate possible interventions targeting impulsivity and sensation-seeking to prevent PUI and SIB in youth.

ABSTRACT

Precisely how intern doctors (or trainee physicians) have been impacted during the COVID-19 pandemic is currently poorly understood. The present study aimed to investigate the mental health consequences (i.e., depression, anxiety, and stress), insomnia, and loneliness among intern doctors in Bangladesh amidst the pandemic. A cross-sectional offline survey of 108 intern doctors (53.7 % female; mean age = 24.80 ± 1.08; age range = 23-29 years) in a large tertiary care hospital in Bangladesh was conducted. The participants were surveyed randomly from respective wards during their duties with an anonymous and self-reported questionnaire assessing socio-demographics, COVID-19-related consideration, mental health, insomnia, loneliness, and other measures. Hierarchical regression analyses were conducted to examine relationships. The prevalence estimates of mild to extremely severe depression, anxiety, and stress were 53.7 %, 63.9 %, and 38.9 %, respectively. Sub-threshold to severe insomnia was acknowledged by 53.7 % and loneliness by 43.5 %. Depression was associated with not receiving mental health counseling during the pandemic, anxiety, stress, and loneliness; anxiety was associated with depression and stress; stress was associated with depression, anxiety, and loneliness; insomnia was associated with being married; and loneliness was associated with poorer quality of life, depression, and stress. Depression, but not anxiety and insomnia, fully mediated the relationship between loneliness and regret regarding choice of profession because of the pandemic and its many unexpected experiences. The findings showed considerable mental health concerns, insomnia, and loneliness among intern doctors in Bangladesh during the COVID-19 pandemic. Future studies should further explore the role of mental health concerns in healthcare providers and perceptions of their profession during the pandemic, and examine interventions to help this vulnerable population.

ABSTRACT

Gaming is popular among youth and gaming disorders have been introduced recently into psychiatric nomenclature systems. Motivations underlying gaming may include involvement to reduce negative emotional states and thus may link to psychiatric and overall health. Thus, the extent to which adolescents engage in gaming to relieve anxiety warrants additional investigation. Data from 2005 Connecticut high-school students were used to examine how adolescents who reported gaming to relieve tension or anxiety differed from those who reported gaming but not to relieve tension or anxiety on measures of demographics, academic performance, general health, extracurricular activities, dysphoria/depression symptoms, substance use, and aggressive or violent behaviors. Chi-square analyses and binomial and multinomial logistic regression models were conducted. Gaming to relieve anxiety was more prevalent in boys and Hispanic and Asian adolescents and associated with less extracurricular involvement, poorer academic performance, increased cigarette and other drug use, problematic internet use, and depression. Participants with gaming to relieve tension or anxiety were also more likely to report weapon-carrying, missing school because they felt unsafe, having been threatened with a weapon, having engaged in physical fights, and having experienced injuries from fights. As gaming to relieve anxiety was related to mental-health- and functioning-related measures, additional research is needed to examine the precise natures of these relationships and to translate the information into improved intervention strategies.

ABSTRACT

Gambling on the lottery is a prevalent behavior, and lottery products are increasingly available in online and electronic formats. As lottery-purchasing is prevalent in adolescents, this study systematically examined relationships between lottery-purchasing and problem-gambling severity and gambling perceptions and attitudes, as well as differences in the relationships between problem-gambling severity and measures of health/functioning and gambling characteristics among lottery-purchasing groups. Participants were 1517 Connecticut high-school adolescents with past-year gambling. Chi-square and logistic regression models were conducted, and interactions between problem-gambling severity and lottery-purchasing status on multiple outcomes were determined. Lottery-purchasing, compared to non-lottery-purchasing, adolescents had greater problem-gambling severity and reported more permissive gambling attitudes and greater parental approval of gambling. Significant between-group differences were observed, with at-risk/problem-gambling more strongly associated with having friends and adult gambling partners among non-lottery-purchasing adolescents, and machine and online gambling, and gambling alone more strongly associated among lottery-purchasing adolescents. Greater problem-gambling severity, permissive gambling attitudes, and parental approval of gambling in lottery-purchasing adolescents suggest that parenting contexts are important considerations in prevention efforts targeting problem gambling in youths. Between-group differences in associations between problem-gambling severity and gambling types and partners may identify high-risk groups associated with more solitary gambling behaviors for whom targeted interventions may be adapted.

ABSTRACT

Stimulant-use disorders have been associated with lower availability of dopamine type-2 receptors (D2R) and greater availability of type-3 receptors (D3R). Links between D2R levels, cognitive performance, and suppression of the default mode network (DMN) during executive functioning have been observed in healthy and addicted populations; however, there is limited evidence regarding a potential role of elevated D3R in influencing cognitive control processes in groups with and without addictions. Sixteen individuals with cocaine-use disorder (CUD) and 16 healthy comparison (HC) participants completed [11C]-(+)-PHNO PET imaging of D2R and D3R availability and fMRI during a Stroop task of cognitive control. Independent component analysis was performed on fMRI data to assess DMN suppression during Stroop performance. In HC individuals, lower D2R-related binding in the dorsal putamen was associated with improved task performance and greater DMN suppression. By comparison, in individuals with CUD, greater D3R-related binding in the substantia nigra was associated with improved performance and greater DMN suppression. Exploratory moderated-mediation analyses indicated that DMN suppression was associated with Stroop performance indirectly through D2R in HC and D3R in CUD participants, and these indirect effects were different between groups. To our knowledge, this is the first evidence of a dissociative and potentially beneficial role of elevated D3R availability in executive functioning in cocaine-use disorder.

ABSTRACT

BACKGROUND AND AIMS: Self-injurious behaviors (SIBs) and problematic shopping (PS) are both prevalent in adolescents. These behaviors have been proposed as behavioral addictions and linked to impulsivity (Imp) and sensation-seeking (SS). They are also associated with negative mental health and psychosocial measures. This study examined relationships between PS and SIB in adolescents. It also examined how PS and SIB relate to Imp and SS, and interactions between PS and SIB in relation to health/functioning measures. METHODS: Survey data from 2,624 Connecticut high-school students were evaluated using chi-square analyses. Next, logistic regression models were used to assess relationships between PS and measures of SIB. T-tests compared Imp and SS in adolescents with and without PS and SIB. Interaction analyses assessed effects of PS on relationships between SIB and health/functioning measures. RESULTS: Adolescents with PS had 3.43-fold higher odds of endorsing lifetime SIB than those without PS, and were more likely to exhibit severe SIB and disruption due to SIB. PS and SIB were associated with elevated Imp and SS. Interaction analyses revealed that in adolescents with PS, the relationships between SIB and substance use was weaker than in adolescents without PS. This suggests PS accounts for variance in relationships between SIB and substance use. DISCUSSION AND CONCLUSIONS: PS is strongly related to SIB prevalence, severity, and impairment in adolescents, and weakens associations between SIB and substance use. PS should therefore be considered for prevention efforts for SIB. Further research should investigate mechanisms connecting PS and SIB and explore possible interventions targeting associated features like Imp and SS.

ABSTRACT

OBJECTIVE: Low parental involvement and monitoring are risk factors for adolescent cigarette use. Assessments of parental involvement and monitoring by youth and parents may capture an additional source of risk: differences in perceptions of these parenting behaviors. This study tested for unique contributions of youth-reported parental involvement and monitoring and youth-parent discrepancies in reporting to first cigarette use in girls. METHOD: Data were drawn from interviews at ages 8-17 with 1,869 girls (57.3% Black, 42.7% White) and their primary caregivers (94% mothers) in the Pittsburgh Girls Study. Cox proportional hazards regression analyses were conducted to predict first cigarette use as a function of girls' reports of parental involvement and monitoring, magnitude and direction of youth-parent reporting discrepancies, and the interaction between them, adjusting for neighborhood, socioeconomic, and individual level factors. RESULTS: High magnitude of discrepancy in parental involvement reports (hazard ratio [HR] = 1.14, 95% confidence interval [CI] [1.03, 1.26]) and lower perceived parental involvement by girls (HR = 1.14, CI [1.03, 1.27]) were associated with an elevated risk for first cigarette use. Girls' reports of low parental monitoring also predicted first cigarette use (HR = 1.14, CI [1.06, 1.21]). CONCLUSIONS: Girls whose parents have limited awareness of their whereabouts and friends (i.e., low monitoring) are at an elevated risk for trying cigarettes, but parent-daughter differences in perceived awareness do not affect risk. By contrast, girls who perceive a lower degree of parental involvement than their parents do are at increased risk. Monitoring is one component of parenting that may reduce smoking risk; shared perspectives on the parent's level of involvement are similarly important.

ABSTRACT

BACKGROUND AND OBJECTIVES: Exposure to early-life trauma may lead to maladaptive characteristics such as alexithymia, and thus to poorer emotional regulation. This relationship may also be influenced by exposure to substances prenatally. We hypothesized that increased alexithymia would be seen in those with prenatal cocaine exposure (PCE). Additionally, we hypothesized that early-life trauma would be associated with alexithymia, and that alexithymia would be associated with poor emotional reappraisal and emotional suppression. METHODS: A moderated mediation model was developed to examine whether the hypothesized indirect relationship between trauma and emotional reappraisal through alexithymia was different in young adults with and without PCE (Total N = 57). Thirty-seven young adults with PCE and 20 with no such exposure, all of whom were members of a longitudinal cohort, were recruited for the study, and data concerning childhood trauma, alexithymia, and emotional regulation were collected. Intercorrelations were performed between the scores on each measure and moderated mediation models were constructed separately with emotional neglect or emotional abuse as the independent variable and emotional reappraisal or emotional suppression as the dependent variable. RESULTS: PCE status was associated with alexithymia, and alexithymia mediated the relationship between emotional neglect and emotional reappraisal in individuals with PCE but not those without. DISCUSSION AND CONCLUSIONS: The data suggest that alexithymia is a mechanism underlying poor use of emotional reappraisal in PCE individuals. SCIENTIFIC SIGNIFICANCE: Individuals with early-life trauma and substance exposure may represent a vulnerable population, and alexithymia may play a key role in the development of emotional regulation skills in this population.

ABSTRACT

The study systematically examined the link between history of gambling, and substance-use and violence-related measures in male and female adolescents, and compared association differences between genders in representative youth risk behavior surveillance data. An anonymous survey was administered to 2425 9th- to 12th-grade students in the state of Connecticut to assess risk behaviors that impact health. Reported past-12-months gambling was the independent variable of interest. Chi squares and adjusted odds-ratios were computed to determine gambling associations with demographic variables, substance-use, and violence-related measures, and whether associations were different between genders. Among students, 18.6% reported gambling. Reported gambling in males and females associated with lifetime use of any drugs, marijuana, cocaine, inhalants, heroin, methamphetamines, ecstasy, synthetic marijuana, non-medical pain-relievers, and injected drugs, in addition to past-30-days cigarette smoking, alcohol and heavy alcohol drinking, and marijuana use. Gambling associated with reported weapon-carrying, being threatened or injured with a weapon, forced sexual intercourse, bullying, and electronic bullying in males; physical dating violence in females; and physical fighting and sexual dating violence in both groups. Gambling and gender interaction terms did not associate with outcome measures except synthetic marijuana use, which trended towards significance (P = 0.052). Gambling in adolescence was similarly linked to risk behaviors involving substance-use in males and females, though gambling relationships with different violence-measures varied between genders. Assessing gambling behavior may be important for targeted preventions focused on adolescents at risk for substance-use disorder and physical violence.
