Abstract
Introduction: As more states pass recreational cannabis laws (RCLs) for adults, there is concern that increasing (and state-sanctioned) cannabis acceptance will result in a reduced perception of risk of harm from cannabis among children. We aimed to discover whether children in states with RCLs had decreased perception of risk from cannabis compared with children in states with illicit cannabis. Methods: We analyzed data from the multisite multistate Adolescent Brain and Cognitive Development Study to determine how the perception of cannabis harm among children (age at baseline: 9-10; N=10,395) changes over time in states with and without RCLs. Using multilevel modeling, we assessed survey responses from children longitudinally across 3 years, adjusting for state-, family-, and participant-level clustering and child-level factors, including demographics (sex, race, and socioeconomic status), religiosity, and trait impulsivity. Results: There was no significant main effect of state RCLs on perceived risk of cannabis use, and no differences in change over time by state RCLs, even after controlling for demographic factors and other risk (e.g., impulsivity) and protective (e.g., religiosity) factors. Conclusions: This analysis indicates that state-level RCLs are not associated with differential perception of cannabis risk among children, even after controlling for demographics, trait impulsivity, and religiosity. Future studies could assess how perception of risk from cannabis changes as children and adolescents continue to mature in states with and without RCLs.

Abstract
The aim of this study was to examine the parenting characteristics of young patients with bipolar disorder (BD) and explore the sex differences. The parental rearing pattern of young patients with BD was measured and compared with the healthy control of young adults. The EMBU scale was used to assess parental rearing patterns. Patients with BD reported significantly higher scores in the punishment and severity index, as well as of the rejection and denial index, but lower scores in the warmth & affectionate index in the paternal rearing pattern, compared with healthy controls. In addition, patients scored higher on the punishment and severity index and rejection and patterns index in maternal rearing patterns. More importantly, we found significant sex differences in maternal rearing patterns (pBonferroni < 0.05). Specifically, in the maternal rearing patterns, male patients had higher scores on the favoring index than male controls, whereas female patients had lower scores on the warmth & affectionate index than female controls. This study shows significant differences in parental rearing patterns between patients and control subjects. Male patients were overprotective by their mothers and female patients were overlooked by their mothers during upbringing.

Abstract
In humans, exposure to early life stress (ELS) is an established risk factor for the development of substance use disorders (SUDs) during later life. Similarly, rodents exposed to ELS involving disrupted mother-infant interactions, such as maternal separation (MS) or adverse caregiving due to scarcity-adversity induced by limited bedding and nesting (LBN) conditions, also exhibit long-term alterations in alcohol and drug consumption. In both humans and rodents, there is a range of addiction-related behaviors that are associated with drug use and even predictive of subsequent SUDs. In rodents, these include increased anxiety-like behavior, impulsivity, and novelty-seeking, altered alcohol and drug intake patterns, as well as disrupted reward-related processes involving consummatory and social behaviors. Importantly, the expression of these behaviors often varies throughout the lifespan. Moreover, preclinical studies suggest that sex differences play a role in how exposure to ELS impacts reward and addiction-related phenotypes as well as underlying brain reward circuitry. Here, addiction-relevant behavioral outcomes and mesolimbic dopamine (DA) dysfunction resulting from ELS in the form of MS and LBN are discussed with a focus on age- and sex-dependent effects. Overall, these findings suggest that ELS may increase susceptibility for later life drug use and SUDs by interfering with the normal maturation of reward-related brain and behavioral function.

Abstract
Borderline personality disorder has been identified as a risk factor for polydrug use. Despite this, there remains a lack of understanding of which characteristics of the disorder provide the mechanisms for this relationship. This study examined a set of constructs as mechanisms explaining the borderline personality disorder-polydrug use relationship that are divided into affective and cognitive categories. The Pathways to Desistance data were used in analyses. Generalized structural equation modeling was used to examine the direct relationship between borderline personality disorder and test for attenuation of this direct effect. A bootstrap resampling process was used to estimate standard errors utilized to specify specific and total indirect effects of mechanism variables and their significance level. Results indicated that greater symptom severity of borderline personality disorder predicted increased drug use variety. This relationship was attenuated by 70% when hypothesized mechanisms were included and became nonsignificant. It appeared that this attenuation was mainly due to sensation-seeking. Findings indicate that interventions for individuals suffering from borderline personality disorder with polydrug use issues may find utility in structuring programming around mitigating sensation-seeking.

Abstract
This review aims to elucidate environmental and genetic factors, as well as their epigenetic and neuroendocrine moderators, that may underlie the association between early childhood experiences and Substance Use Disorders (SUD), through the lens of parental attachment. Here we review those attachment-related studies that examined the monoaminergic systems, the hypothalamic pituitary adrenal stress response system, the oxytoninergic system, and the endogenous opioid system from a genetic, epigenetic, and neuroendocrine perspective. Overall, the selected studies point to a moderating effect of insecure attachment between genetic vulnerability and SUD, reasonably through epigenetic modifications. Preliminary evidence suggests that vulnerability to SUDs is related with hypo-methylation (e.g. hyper-expression) of high-risk polymorphisms on the monoaminergic and hypothalamic pituitary adrenal system and hyper-methylation (e.g. hypo-expressions) of protective polymorphisms on the opioid and oxytocin system. These epigenetic modifications may induce a cascade of neuroendocrine changes contributing to the subclinical and behavioural manifestations that precede the clinical onset of SUD. Protective and supportive parenting could hence represent a key therapeutic target to prevent addiction and moderate insecure attachment.

Abstract
BACKGROUND AND AIM OF THE WORK Illicit drug (ID) use/abuse represent a social and economic burden for most countries worldwide which, in spite of the efforts to prevent this phenomena, is often a growing habit especially in the young adults. Preventive measurements, are needed to reduce the adverse health and social consequences of ID use/abuse. METHODS This study investigated the relationship between coping strategies and ID use in students (N=12316) from the University of Parma, Italy. Information about the ID use in the past 12 months and coping strategies were collected with a cross-sectional research design using an online questionnaire. RESULTS More than 25% of the participants used ID in the past year; men were more likely to use drugs than female; the likelihood of using drugs was inversely related to age. The relationship between coping strategies and ID use was analyzed with a multilevel logistic model taking into account the within-department nested structure of data. Analysis revealed that transcendence-orientation and problem-orientation were associated with a reduction of the likelihood to have used drugs. Conversely, avoidance and positive attitude were associated with an increase of the likelihood to have used drugs. Finally, seeking social support revealed a positive but modest association with increasing in drug use. CONCLUSIONS The ID use association factors identified in this study could be utilized by the appropriate institutions/authorities as a critical review in order to develop relevant public health policies and preventive measures aimed at minimizing the use of ID in this critical age group.

ACCIDENT; ANALYSIS AND PREVENTION 2020; 148:105715.

Abstract
Seat belt use can significantly reduce fatalities in motor vehicle crashes (Kahane, 2000). Nevertheless, the current U.S. seat belt use rate of 89.6% (Enriquez & Pickrell, 2019) indicates that a relatively small but pervasive portion of the population does not wear seat belts on a full-time basis. Whereas much is known about the demographic predictors of seat belt use, far less is understood about psychological factors that predict individual proclivities toward using or not using a seat belt. In this study, we examined some of these potential psychological predictors. A probability-based web survey was conducted with 6,038 U.S. residents aged 16 or older who reported having driven or ridden in a car in the past year. We measured self-reported seat belt use and 18 psychological constructs and found that delay of gratification, life satisfaction, risk aversion, risk perception, and resistance to peer influence were positively associated with belt use. Impulsivity and social resistance orientation were negatively associated with belt use. Prior research has shown that psychological factors like delay of gratification, risk aversion/perception, and impulsivity predict other health behaviors (e.g., cigarette smoking, sunscreen use); our results extend this literature to seat belts and can aid the development of traffic safety programs targeted at non-users who-due to such factors-may be resistant to more traditional countermeasures such as legislation and enforcement.

Abstract
The diagnosis of substance use disorder is currently based on the presence of specifically identified behavioral symptoms. In addition, other psychiatric signs and symptoms accompany addictive behavior, contributing to the full picture of patients’ psychopathologic profile. Historically, such symptoms were confined within the framework of “comorbidity”, as comorbid psychiatric disorders or personality traits. However, an alternative unitary view of the psychopathology of addiction, inclusive of related psychiatric symptoms, has been claimed, with the support of epidemiological, neurobiological, and neuropsychological evidence. In the present article, we highlight the research advancements that strengthen this unified perspective. We then give an account of our group’s definition of a specific SCL-90-based construct of the psychopathology of addiction. Lastly, we discuss the benefits that can be expected to be acquired in the evaluation and treatment of patients with a longitudinal approach including psychological/psychiatric predisposing features, addictive behavior, and psychiatric manifestations.

Abstract
Poor early relationship experiences during the first 16 years of life may negatively impact adults' capacity to establish and utilize social support (Suchman, McMahon, Slade, & Luthar, 2005). This is especially of concern for women with substance use disorders (SUD) for whom social support is associated with recovery maintenance and treatment retention (Gregoire & Snively, 2001). The purpose of this study was to examine the influence of early relationship experiences, specifically paternal and maternal warmth, on recovery related social support and personal network characteristics among African American (AA) and non-AA women in treatment for SUD. Data were collected from 254 women in substance abuse treatment, 146 AA and 108 non-AA. Ordinal logistic, Poisson or multiple linear regressions were fitted to predict the impact of maternal and paternal warmth during childhood on adult social network composition and recovery support. Greater maternal warmth was associated with greater recovery-specific social support for both AA (β = 0.12) and non-AA (β = 0.15) women. Paternal, but not maternal, warmth significantly predicted the number of social network members who supported recovery for non-AA women (AOR = 1.04), and number of network members who used drugs and alcohol for AA women (IRR = 0.99). Developmental experiences associated with fathers appear to affect different domains of adult functioning than those associated with mothers, and those effects are different for AA versus non-AA women. Attention to these differences may inform culturally relevant substance abuse prevention and treatment efforts.

Abstract
Despite the prevalence of drug use within society, only a subset of individuals actively taking addictive drugs lose control over their intake and develop compulsive drug-seeking and intake that typifies substance use disorder (SUD). Although research in this field continues to be an important and dynamic discipline, the specific neuroadaptations that drive compulsive behaviour in humans addicted to drugs and the neurobiological mechanisms that underlie an individual's innate susceptibility to SUD remain surprisingly poorly understood. Nonetheless, it is clear from research within the clinical domain that some behavioural traits are recurrently co-expressed in individuals with SUD, thereby inviting the hypothesis that certain behavioural endophenotypes may be predictive, or at least act in some way, to modify an individual's probability for developing this disorder. The analysis of such endophenotypes and their catalytic relationship to the expression of addiction-related behaviours has been greatly augmented by experimental approaches in rodents that attempt to capture diagnostically relevant aspects of this progressive brain disorder. This work has evolved from an early focus on aberrant drug reinforcement mechanisms to a now much richer account of the putatively impaired cognitive control processes that ultimately determine individual trajectories to compulsive drug-related behaviours. In this chapter we discuss the utility of experimental approaches in rodents designed to elucidate the neurobiological and genetic underpinnings of so-called risk traits and how these innate vulnerabilities collectively contribute to the pathogenesis of SUD.

Abstract
Very little research done on the relationship between identity styles and addiction vulnerability among university students. This study aims to evaluate the extent to which identity styles can influence addiction vulnerability among medical students in Zahedan, Iran. The present cross-sectional study being conducted at Zahedan University of Medical Sciences from 2015 to 2016. The study sample consisted of 205 pre-clinical medical students (60% Female, 40% male) recruited. Berzonsky's Identity Style Questionnaire and Addiction Potential questionnaire, respectively measured "Identity Styles and addiction vulnerability". The multivariate linear analysis was conducted applying backward stepwise selection method. The female students shown more normative oriented than the male ones (p = 0.01). Students living in own house had significantly higher scores for diffuse avoidant style and addiction vulnerability compared with other types of accommodation (p ≤ 0.01). Multivariable regression analysis demonstrated that the final model included accommodation, admission qouta, normative, diffuse-avoidant and commitment styles, as addiction vulnerability may be higher as the results of lower normative style indicated (β = -0.54; 95% confidence interval: -1.00 to -0.08), higher diffuse-avoidant (0.41; 0.09 to 0.74) and lower commitment style (-0.79; -1.22 to -0.37). The study provides direct evidence of potential role of identity formation on the addiction vulnerability among medical students.

INTRODUCTION In the last decade, the comprehension of affective temperaments has helped us to outline the boundaries of mood disorders, and to expand our knowledge of nosographic areas other than those of affectivity, even if affectivity is closely related to them. In the field of substance use disorders, the temperamental profile of heroin addicts and alcoholics has been discussed elsewhere, but no comparison has yet been made between these two patient populations. Such a comparison would help to shed light on the pathogenetic mechanisms that link temperament with substance abuse. METHODS 63 Heroin Use Disorder (HUD) and 94 Alcohol Use Disorder (AUD) patients were compared with 130 healthy controls, with the aim of outlining affective temperament quantity and typology according to the formulation of Akiskal and Mallya. RESULTS Cyclothymic temperamental quantity differentiated - both at the univariate and multivariate levels - between patients who had various different types of Substance Use Disorder, largely irrespective of the principal substance of abuse (heroin or alcohol); irritable temperament quantity differentiated HUD patients from AUD patients. Hyperthymic temperament typology seemed to be more frequent in healthy controls at both univariate and multivariate levels. LIMITATION Cross-sectional study. CONCLUSIONS Our analyses suggest that cyclothymic temperament quantity could best correspond to the temperamental profile of Substance Use Disorder patients independently of principal substance of abuse (alcohol or heroin), and that irritable temperament quantity may differentiate HUD from AUD patients. Hyperthymic temperament typology seemed to be highly protective for HUD and, though a bit less, for AUD patients, and was a typical feature of healthy controls.

Abstract
BACKGROUND AND AIMS Substance use during adolescence can lead to the development of substance use disorders and other psychosocial problems. These negative outcomes are especially likely for individuals who use substances at earlier ages and those who engage in heavier use during adolescence, behaviors which are both more common among youth at higher risk for developing a substance use disorder, such as those with a family history of substance use disorders (FH+). Factors such as increased sensation seeking and greater exposure to stressors among FH+ youth may influence these associations. Therefore, the aim of this study was to examine the relative and unique contributions of sensation seeking during preadolescence and exposure to stressors during early to mid-adolescence to cumulative substance use by mid-adolescence among FH+ youth. METHODS A total of 167 mostly Hispanic FH+ youth (ages 12-15) who were participating in an ongoing longitudinal study were included in these analyses. Participants' data from biennial waves covering approximately 2.5years were used. Self-reported sensation seeking, exposure to stressors, and substance use were compared. RESULTS Higher sensation seeking during preadolescence and greater exposure to stressors during early to mid-adolescence were both associated with substance use by age 15. These factors differentiated Substance Users from Non-Users, and also related to level of substance use. CONCLUSIONS Elevated sensation seeking and exposure to stressors are both associated with substance use by age 15 among high-risk youth. Additionally, these factors can distinguish youth who develop heavier substance use during this important developmental period.

Abstract
A relation between different types of parental care, trauma in childhood and psychotic symptoms in adulthood has been proposed. The nature of this association is not clear and if it is more related to psychotic disorders per se or to a cluster of symptoms such as positive psychotic symptoms remains undefined. We have analysed the presence of childhood trauma using the CTQ scale and types of parental care using the PBI scale in three groups of subjects: borderline personality disorder patients (n=36), first psychotic episode patients (n=61) and healthy controls (n=173). Positive psychotic symptomatology was assessed with the CAPE scale. General linear models were used to study the relation between positive psychotic symptomatology and variables of interest. BPD patients had the highest rate of any kind of trauma, followed by FEP patients. We found a positive relationship between psychotic symptomatology and the existence of trauma in childhood in all groups. Moreover, an affectionless control rearing style was directly associated with the existence of trauma. Furthermore, subjects with trauma presented less probability of having an optimal parenting style in childhood. The relation between psychotic symptoms and trauma remained statistically significant after adjusting for other variables including parental rearing style. There seems to be a link between trauma in childhood and psychotic symptomatology across different populations independently of psychiatric diagnosis. Taking into account that there is an association between trauma and psychosis and that trauma is a modifiable factor, clinicians should pay special attention to these facts.

Abstract
BACKGROUND Adolescents often experiment with drug use, which can impact on their health and well-being and increase the probability of problem drug use. Yet, not enough is known about which psychological indicators is related with the initiation of drug use among young adults and have predictive power. MATERIALS AND METHODS Participants in this study were 311 boys (school and college students) aged 15-17. Data were collected in the towns of Moscow region. A modified version of Dembo-Rubinstein test was used to assess the self-evaluation (SE). A questionnaire and detection of drugs in urine were used to identify drug users. Binary logistic regression analysis based on SE with the inclusion of interactive effects between predictors was used for prediction of drug use. RESULTS Drug users, compared to nondrug users, are characterized by lower actual SE of health, happiness, success in learning, mind and desired SE of appearance, and higher desired SE of relationships with friends. The developed nonlinear regression model for prediction of boys' involvement in drug use among young boys in the towns of Moscow region has a sensitivity of 82.7% at a specificity of 79.0%. CONCLUSIONS Dembo-Rubinstein test of SE is a sensitive measure to identify boys at risk of involvement in drug use. Application of the regression model based on SE may contribute to the useful solution in preventing any onset of early drug use.

Abstract
Addiction is a mental illness in which psychiatric conditions imply a prominent burden. Psychopathological symptoms in substance use disorder (SUD) patients are usually viewed as being assignable to the sphere of a personality trait or of comorbidity, leaving doubts about the presence of a specific psychopathology that could only be related to the toxicomanic process. Our research group at the University of Pisa has shed light on the possible definition of a specific psychopathological dimension in SUDs. In heroin use disorder patients, performing an exploratory principal component factor analysis (PCA) on all the 90 items included in the SCL-90 questionnaire led to a five-factor solution. The first factor accounted for a depressive "worthlessness and being trapped" dimension; the second factor picked out a "somatic symptoms" dimension; the third identified a "sensitivity-psychoticism" dimension; the fourth a "panic-anxiety" dimension; and the fifth a "violence-suicide" dimension. These same results were replicated by applying the PCA to another Italian sample of 1,195 heroin addicts entering a Therapeutic Community Treatment. Further analyses confirmed the clusters of symptoms, independently of demographic and clinical characteristics, active heroin use, lifetime psychiatric problems, kind of treatment received, and, especially, other substances used by the patient such as alcohol or cocaine. Moreover, these clusters were able to discriminate patients affected by addiction from those affected by psychiatric diseases such as major depressive disorder. Our studies seem to suggest the trait-dependent, rather than the state-dependent, nature of the introduced psychopathology dimensions of SUDs.

Abstract
BACKGROUND Impulsivity is often included as a risk factor in models of adolescent marijuana use behaviors; however, the magnitude of the association between impulsivity and marijuana use behaviors is variable across studies. The present study reviewed existent literature to 1) quantify the relationship between separable impulsivity-related traits and both marijuana use and negative marijuana consequences and 2) quantify the size of the effect of gender on these relationships. METHOD Thirty-eight studies (41 independent samples) were meta-analyzed using a random effects model to examine the relationship between impulsivity traits and marijuana use behaviors. RESULTS Marijuana use was significantly related to all impulsivity-related traits except lack of perseverance (r's ranging from 0.13-0.23, p's<0.01). Negative marijuana consequences were only significantly related to sensation seeking, lack of planning, and positive urgency (r's ranging from 0.37-0.39, p's<0.01). Effects were small for marijuana use, but medium for negative marijuana consequences. Gender was not a significant moderator of any relationships. CONCLUSIONS Impulsivity-related traits had more robust relationships with negative marijuana consequences than marijuana use, suggesting impulsivity-related traits are important in differentiating adolescents most likely to experience negative consequences from marijuana use. Few relationships examined gender and many of the impulsivity-related traits, other than sensation seeking. Data and trends suggest a more multi-dimensional approach to marijuana use and consequences is warranted.

Abstract
A number of studies have associated impulsivity and sensation seeking with level of substance use and risk for developing a substance use disorder. These relationships may be particularly apparent during adolescence, when developmental changes in impulsivity and sensation seeking occur at the same time as increased opportunities for substance use. To examine this, the current study measured impulsivity and sensation seeking from pre-adolescence to mid-adolescence in a sample of youth, the majority of whom were identified as being at risk for developing a substance use disorder based on their family history of substance use disorders. Youth were separated into those who did (n=117) and did not (n=269) initiate substance use by mid-adolescence. Results showed that substance users were more impulsive and more sensation seeking during pre-adolescence, prior to any significant substance use, and that greater sensation seeking in pre-adolescence was related to heavier substance use by mid-adolescence. In addition, developmental trajectories for substance-using youth showed a greater increase in sensation seeking but a more modest decrease in impulsivity from pre-adolescence to mid-adolescence. Taken together, these results indicate that increased impulsivity and sensation seeking is apparent in adolescent substance users as early as pre-adolescence, that the difference between substance users and non-users becomes larger across early adolescence as their developmental trajectories diverge, and that greater sensation seeking in pre-adolescence may predict increased substance use by mid-adolescence.

Abstract
Families in which one or more members are undocumented immigrants experience unique hardships. Yet, little is known about stress and substance use among adolescents growing up in these families. The present study examined associations between two sources of adolescent stress (i.e., low parental involvement due to contextual constraints and family economic insecurity) and lifetime alcohol, cigarette, and marijuana use among adolescents in families with undocumented members. The sample was comprised of 102 adolescents (10-18 years old) and one of his or her parents. Participants responded a survey in English or Spanish. Adolescent lifetime use of alcohol, cigarette, and marijuana was 51%, 32.4%, and 37.3%, respectively. Chi-Square analyses found no significant gender differences in lifetime substance use. Logistic regression models showed that adolescent stress due to hindered parental involvement increased the odds of both lifetime cigarette and marijuana use after controlling for gender, age, linguistic acculturation, familism, parental control, and negative peer affiliation. Being a girl increased the odds of lifetime alcohol use. Family economic stress was not associated with lifetime substance use. Results suggest that hindered parental involvement might be a stressor and a risk factor for cigarette and marijuana use among adolescents growing up in families with undocumented members. Because parents in these families are likely to be undocumented, policies that allow immigrants to apply for legal status could improve parents' working conditions and facilitate parental involvement; in turn, such policies could decrease the risk for adolescent substance use among children of Latino immigrants.

Abstract
The Parental Bonding Instrument (PBI) is a widely used self-report measure for quantifying key parenting styles as perceived by the child during its first 16 years. While its development study identified two key parental dimensions, subsequent studies have variably confirmed those two or argued for one or more additional parental constructs. We developed a Persian translation of the PBI and administered it to a sample of 340 high school students. The construct validity of the Persian PBI was examined by Exploratory Factor Analysis while Confirmatory Factor Analysis was used to identify the most adequate model. Analyses of the Persian PBI favored a four-factor model for both parental forms. The Persian PBI has a factorial structure consistent with constructs identified in western cultures, as well as high internal consistency and test-retest reliability. Multivariate analyses indicated significant differences between boys and girls across some factors. The PBI appears an acceptable and appropriate measure for quantifying parent-child bonding in Iranian samples.

Abstract
BACKGROUND Risk-based decision making is altered in people with schizophrenia and in people with cannabis use compared to healthy controls; the pattern of risk-assessment in people with co-occurring schizophrenia and cannabis dependence is poorly understood. This study examined measures of risk-taking and decision-making in people with and without schizophrenia and/or cannabis dependence. METHODS Participants with schizophrenia (n=24), cannabis dependence (n=23), schizophrenia and co-occurring cannabis dependence (n=18), and healthy controls (n=24) were recruited from the community via advertisements and completed a one-visit battery of symptom, risk-based decision making, gambling behavior, cognitive, and addiction assessments. This report presents self-assessments of self-mastery, optimism, impulsivity, and sensation seeking and a behavioral assessment of risk (Balloon Analog Risk Task [BART]). RESULTS On self-report measures, participants with schizophrenia and co-occurring cannabis dependence were intermediate between those with only cannabis dependence or only schizophrenia on ratings of self-mastery, sensation-seeking, and impulsivity. There were no group differences on ratings of optimism. Their behavior on the BART was most similar to participants with only cannabis dependence or healthy controls, rather than to participants with only schizophrenia. CONCLUSIONS People with schizophrenia and co-occurring cannabis dependence may represent a unique group in terms of risk-perception and risk-taking. This has implications for interventions designed to influence health behaviors such as motivational interviewing.

Abstract
BACKGROUND The influence of family factors on the development and/or on maintenance of heroin addiction still remains unclear. OBJECTIVES The aim of this study was to investigate family factors, which might be associated with heroin addiction in a sample of male individuals. METHODS A group of 40 heroin addicts' families was compared with a group of 17 families with a member presenting schizophrenia and a group of 27 families with mentally healthy members in regard to (1) parents' rejection attitudes toward their adult child, (2) quality of parental bond, as perceived by the adult child, and (3) stressful life events in the nuclear family. RESULTS The main findings showed that the degree of rejection by the fathers in the heroin addicts' families as well as in the subjects with schizophrenia was significantly higher compared to the fathers' degree of rejection in the control group. Moreover, the degree of rejection by mothers in the heroin addicts' families was significantly higher compared to the mothers' degree of rejection in the control group. Heroin addicts reported that they had perceived less care from their fathers than healthy controls. The total number of stressful life events in the nuclear family was higher in the patients with schizophrenia in comparison to the healthy controls. Also, in the heroin addicts' group, a significantly higher number of fathers presented a current or past psychiatric disorder. CONCLUSIONS The findings of this study showed the importance of negative family factors in the course of heroin addiction.

Abstract
PURPOSE A meta-analysis of empirical studies performed in Korea was conducted to systematically investigate the associations between the indices of Internet addiction (IA) and psychosocial variables. MATERIALS AND METHODS Systematic literature searches were carried out using the Korean Studies Information Service System, Research Information Sharing Service, Science Direct, Google Scholar, and references in review articles. The key words were Internet addiction, (Internet) game addiction, and pathological, problematic, and excessive Internet use. Only original research papers using Korean samples published from 1999 to 2012 and officially reviewed by peers were included for analysis. Ninety-five studies meeting the inclusion criteria were identified. RESULTS The magnitude of the overall effect size of the intrapersonal variables associated with internet addiction was significantly higher than that of interpersonal variables. Specifically, IA demonstrated a medium to strong association with "escape from self" and "self-identity" as self-related variables. "Attention problem", "self-control", and "emotional regulation" as control and regulation-relation variables; "addiction and absorption traits" as temperament variables; "anger" and "aggression" as emotion and mood and variables; "negative stress coping" as coping variables were also associated with comparably larger effect sizes. Contrary to our expectation, the magnitude of the correlations between relational ability and quality, parental relationships and family functionality, and IA were found to be small. The strength of the association between IA and the risk and protective factors was found to be higher in younger age groups. CONCLUSION The findings highlight a need for closer examination of psychosocial factors, especially intrapersonal variables when assessing high-risk individuals and designing intervention strategies for both general IA and Internet game addiction.

Links between Psychotropic Substance Use and Sensation Seeking in a Prevalence Study: The Role of Some Features of Parenting Style in a Large Sample of Adolescents. JOURNAL OF ADDICTION 2014; 2014:962178. [PMID: 25332837 PMCID: PMC4190272 DOI: 10.1155/2014/962178] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2014] [Revised: 08/01/2014] [Accepted: 08/27/2014] [Indexed: 11/17/2022]
Abstract
Aims. The objectives of the study were to (a) investigate the prevalence risk of current drug users and (b) explore the association between parental monitoring, adolescent-parent relationship, family structure, financial status, and sensation-seeking and psychotropic substance use. Methods. Data were drawn from the 2002 Italian student population survey of the European School Survey Project on Alcohol and Other Drugs. The sample size was 10,790 adolescents, aged 15-19 years. Multivariate logistic analyses were performed. Findings. The prevalence of users was 27.3% (34.2% males; 21.6% females). Single-parent and reconstructed families were related to the greatest likelihood of substance use. A medium financial status and, for females, a satisfying relationship with father were protective factors. Probability of engaging in risk-taking behavior increased when parental knowledge decreased. Exploring deeper how parental monitoring could modify the relation between different traits of sensation seeking and substances use revealed the following: "thrill and adventure seeking," within the case of a good monitoring, can help against the use of substances; "boredom susceptibility" is not associated with drug use, except when parental monitoring is weak. Conclusions. Specific subdimensions, associated with substance use, may be more amenable to prevention than general interventions on sensation-seeking personality. Family is the context that could promote health education.

Abstract
Associating with substance using peers is generally considered as one of the most important predictors of adolescent substance use. However, peer association does not affect all adolescents in the same way. To better understand when and under what conditions peer association is most linked with adolescent substance use (SU), this review focuses on the factors that may operate as moderators of this association. The review highlighted several potential moderators reflecting adolescents' individual characteristics (e.g., pubertal status, genes and personality), peer and parental factors (e.g., nature of relationships and parental monitoring), and contextual factors (e.g., peer, school and neighborhood context). As peer association is a broad concept, important methodological aspects were also addressed in order to illustrate how they can potentially bias interpretation. Taking these into account, we suggest that, while the effects of some moderators are clear (e.g., parental monitoring and sensation seeking), others are less straightforward (e.g., neighborhood) and need to be further examined. This review also provides recommendations for addressing different methodological concerns in the study of moderators, including: the use of longitudinal and experimental studies and the use of mediated moderation. These will be key for developing theory and effective prevention.

Abstract
BACKGROUND The relationship between substance use disorders and psychiatric pathology is still an open question. The main aim of the present study was to verify whether the five psychopathological dimensions identified through the SCL-90 tool in a previous study carried out on patients with heroin addiction entering an outpatient opioid agonist treatment (OAT) were also observable in those entering a residential treatment community (TC). Further aims were to look at differences in the psychopathological profiles of patients entering a TC versus an OAT treatment and at the correlation between gender and the observed psychopathology. METHODS A confirmatory factor analysis was performed on the results of SCL-90 filled by 1,195 patients with heroin dependence entering TC treatment. It replicates the extraction method previously used on 1,055 OAT patients with heroin addiction by using a principal component factor analysis (PCA). The association between the kind of treatment received (TC or OAT), gender, and the psychopathological dimensions was assessed through logistic regression and general linear model (GLM) analysis. RESULTS The PCA carried out on the SCL-90 results of patients entering a TC yielded a five-factor solution, confirming the same dimensions observed in patients entering an OAT: 'worthlessness and being trapped', 'somatization', 'sensitivity-psychoticism', 'panic anxiety', and 'violence-suicide'. The logistic regression analysis showed a statistically significant association between 'somatization' and 'violence-suicide' severity score and OAT. GLM analysis showed that psychopathological factorial scores for 'worthlessness-being trapped', 'somatic symptoms', and 'panic anxiety' dimensions were more severe in OAT vs TC male patients and in TC vs OAT female ones. 'Violence suicide' followed the same severity pattern for males, but did not differ in TC vs OAT females, while 'sensitivity-psychoticism' did not differ in OAT vs TC patients. The five dimensions did not differ in OAT males vs females. CONCLUSIONS Our research appears to confirm the existence of a specific aggregation of psychological/psychiatric features within the category of individuals with heroin addiction. It also shows a correlation between the dominant psychopathological subgroup and the assignment to TC versus OAT. Further research is needed to clarify the differences between the five psychopathological subgroups and their determinants.

Abstract
Transition to addiction is the shift from controlled to uncontrolled drug use that occurs after prolonged drug intake in a limited number of drug users. A major challenge of addiction research in recent years has been to develop models for studying this pathological transition. Toward this goal, a DSM-IV/5-based multi-symptomatic model of cocaine addiction has been developed in the rat. It is based on an operational translation of the main features of the disease. 1. Addiction is not just taking drug; it is a non-adaptive drug use: The procedure models addiction in relation to its clinical definition. 2. All drug users do not face the same individual risk of developing addiction: The model includes an individual-based approach. 3. Addiction develops after protracted periods of controlled drug use: This procedure allows for the study of the long-term shift from controlled drug use to addiction. We describe this model in detail and show how it can contribute to our understanding of the pathophysiology of cocaine addiction. This article is part of a Special Issue entitled 'NIDA 40th Anniversary Issue'.

Abstract
BACKGROUND Stimulant drugs such as cocaine and amphetamine have a high abuse liability, but not everyone who uses them develops dependence. However, the risk for dependence is increased for individuals with a family history of addiction. We hypothesized that individuals without a family history of dependence who have been using cocaine recreationally for several years but have not made the transition to dependence will differ in terms of personality traits and brain structure from individuals who are either dependent on stimulants or at risk for dependence. METHODS We compared 27 individuals without a familial risk of dependence who had been using cocaine recreationally with 50 adults with stimulant dependence, their nondependent siblings (n = 50), and unrelated healthy volunteers (n = 52) who had neither a personal nor a family history of dependence. All participants underwent a magnetic resonance imaging brain scan and completed a selection of personality measures that have been associated with substance abuse. RESULTS Increased sensation-seeking traits and abnormal orbitofrontal and parahippocampal volume were shared by individuals who were dependent on stimulant drugs or used cocaine recreationally. By contrast, increased levels of impulsive and compulsive personality traits and limbic-striatal enlargement were shared by stimulant-dependent individuals and their unaffected siblings. CONCLUSIONS We provide evidence for distinct neurobiological phenotypes that are either associated with familial vulnerability for dependence or with regular stimulant drug use. Our findings further suggest that some individuals with high sensation-seeking traits but no familial vulnerability for dependence are likely to use cocaine but may have relatively low risk for developing dependence.

Abstract
This article reviews recent advances in the elucidation of neurobehavioral endophenotypes associated with drug addiction made possible by the translational neuroimaging techniques magnetic resonance imaging (MRI) and positron emission tomography (PET). Increasingly, these non-invasive imaging approaches have been the catalyst for advancing our understanding of the etiology of drug addiction as a brain disorder involving complex interactions between pre-disposing behavioral traits, environmental influences and neural perturbations arising from the chronic abuse of licit and illicit drugs. In this article we discuss the causal role of trait markers associated with impulsivity and novelty-/sensation-seeking in speeding the development of compulsive drug administration and in facilitating relapse. We also discuss the striking convergence of imaging findings from these behavioural traits and addiction in rats, monkeys and humans with a focus on biomarkers of dopamine neurotransmission, and highlight areas where further research is needed to disambiguate underlying causal mechanisms.

Abstract
Epidemiological studies have revealed striking associations between several distinct behavioral/personality traits and drug addiction, with a large emphasis on the sensation-seeking trait and the associated impulsive dimension of personality. However, in human studies, it is difficult to identify whether personality/behavioral traits actually contribute to increased vulnerability to drug addiction or reflect psychobiological adaptations to chronic drug exposure. Here we show how animal models, including the first multi-symptomatic model of addiction in the rat, have contributed to a better understanding of the relationships between different subdimensions of the sensation-seeking trait and different stages of the development of cocaine addiction, from vulnerability to initiation of cocaine self-administration to the transition to compulsive drug intake. We argue that sensation seeking predicts vulnerability to use cocaine, whereas novelty seeking, akin to high impulsivity, predicts instead vulnerability to shift from controlled to compulsive cocaine use, that is, addiction.

Abstract
Altered reactivity to stress, either in the direction of exaggerated reactivity or diminished reactivity, may signal a dysregulation of systems intended to maintain homeostasis and a state of good health. Evidence has accumulated that diminished reactivity to psychosocial stress may signal poor health outcomes. One source of diminished cortisol and autonomic reactivity is the experience of adverse rearing during childhood and adolescence. The Oklahoma Family Health Patterns Project has examined a cohort of 426 healthy young adults with and without a family history of alcoholism. Regardless of family history, persons who had experienced high degrees of adversity prior to age 16 had a constellation of changes including reduced cortisol and heart rate reactivity, diminished cognitive capacity, and unstable regulation of affect, leading to behavioral impulsivity and antisocial tendencies. We present a model whereby this constellation of physiological, cognitive, and affective tendencies is consistent with altered central dopaminergic activity leading to changes in brain function that may foster impulsive and risky behaviors. These in turn may promote greater use of alcohol other drugs along with adopting poor health behaviors. This model provides a pathway from early life adversity to low stress reactivity that forms a basis for risky behaviors and poor health outcomes.

Abstract
AbstractGirls receiving lower quality paternal investment tend to engage in more risky sexual behavior (RSB) than peers. Whereas paternal investment theory posits that this effect is causal, it could arise from environmental or genetic confounds. To distinguish between these competing explanations, the current authors employed a genetically and environmentally controlled sibling design (N = 101 sister pairs; ages 18–36), which retrospectively examined the effects of differential sibling exposure to family disruption/father absence and quality of fathering. Consistent with a causal explanation, differences between older and younger sisters in the effects of quality of fathering on RSB were greatest in biologically disrupted families when there was a large age gap between the sisters (thus maximizing differential exposure to fathers), with greater exposure within families to higher quality fathering serving as a protective factor against RSB. Further, variation around the lower end of fathering quality appeared to have the most influence on RSB. In contrast, differential sibling exposure to family disruption/father absence (irrespective of quality of fathering) was not associated with RSB. The differential sibling-exposure design affords a new quasi-experimental method for evaluating the causal effects of fathers within families.

Abstract
Cocaine is the most widely used club drug. Yet, little is known about how patterns of cocaine use vary over time among young adults of diverse gender and sexual identities. This study used latent class growth analysis to identify trajectories of cocaine use over a year and explored individual and substance use factors associated with these trajectories. A sample of 400 young adults (mean age=23.9 years) with recent club drug use were recruited from New York City bars and nightclubs using time-space sampling. Participants completed quantitative measures at baseline, 4-, 8- and 12-months follow-up. A 4-class model fit the data best. Patterns were: Consistent use (48%), Inconsistent use (14%), Decreasing Likelihood of use (28%), and Consistent non-use (11%). Those most likely to be in the Consistent use class had the highest frequency of baseline club drug dependence (χ2 (3, 397)=15.1, p<.01), cocaine dependence (χ2 (3, 397) = 18.9, p<.01), recent alcohol use (χ2 (3, 397)=12.48, p<.01), and drug sensation-seeking (χ2 (3, 397)=9.03, p<.01). Those most likely to be in the Consistent Non-use class had the highest frequency of baseline marijuana use (χ2 (3, 397)=2.71, p<.05). Contrary to hypotheses, there were no differences in most-likely trajectory class by gender/sexual-orientation, age, ethnicity, education, employment status, or income. Findings highlight the diversity of cocaine use patterns over time among young adults, and the personal and substance use characteristics that are associated with each.

Abstract
BACKGROUND The liability to addiction has been shown to be highly genetically correlated across drug classes, suggesting nondrug-specific mechanisms. METHODS In 757 subjects, we performed association analysis between 1536 single nucleotide polymorphisms (SNPs) in 106 candidate genes and a drug use disorder diagnosis (DUD). RESULTS Associations (p ≤ .0008) were detected with three SNPs in the arginine vasopressin 1A receptor gene, AVPR1A, with a gene-wise p value of 3 × 10(-5). Bioinformatic evidence points to a role for rs11174811 (microRNA binding site disruption) in AVPR1A function. Based on literature implicating AVPR1A in social bonding, we tested spousal satisfaction as a mediator of the association of rs11174811 with the DUD. Spousal satisfaction was significantly associated with DUD in males (p < .0001). The functional AVPR1A SNP, rs11174811, was associated with spousal satisfaction in males (p = .007). Spousal satisfaction was a significant mediator of the relationship between rs11174811 and DUD. We also present replication of the association in males between rs11174811 and substance use in one clinically ascertained (n = 1399) and one epidemiologic sample (n = 2231). The direction of the association is consistent across the clinically-ascertained samples but reversed in the epidemiologic sample. Lastly, we found a significant impact of rs11174811 genotype on AVPR1A expression in a postmortem brain sample. CONCLUSIONS The findings of this study call for expansion of research into the role of the arginine vasopressin and other neuropeptide system variation in DUD liability.

Abstract
BACKGROUND Individuals who begin drinking during early adolescence and exhibit externalizing pathology and disinhibitory/dysregulatory tendencies are more vulnerable to developing alcohol use disorders (AUDs) in adulthood. Previous research has focused on in-treatment populations with substantial comorbid psychopathology and polysubstance use. Here, we characterize a unique sample of treatment-naïve adolescents without such comorbidity to help identify vulnerable youth who may benefit from early intervention. METHODS We compared externalizing propensity, disinhibitory characteristics, and school performance in adolescents with AUDs (but without comorbid psychopathology or other substance use; n = 70) to those of demographically matched controls (n = 70). Within the AUD group, we compared measures of substance use and the disinhibitory syndrome between boys and girls with differing severity of externalizing propensity. RESULTS Adolescents with AUDs demonstrated more externalizing propensity and disinhibitory personality traits (impulsivity, novelty seeking, and excitement seeking), poorer self-monitoring and response inhibition, more bullying and sexual risk-taking behavior, poorer first-language performance, and greater use of alcohol, cannabis, and nicotine (p < 0.05). Within the AUD group, participants with higher externalizing propensity began drinking earlier, more frequently, and for a longer duration than those with lower externalizing symptoms (p < 0.05). Disinhibitory features (personality, cognition, and behavior) were, however, not stronger in those with higher externalizing propensity. CONCLUSIONS We suggest that the constructs of externalizing propensity and disinhibitory syndrome are useful in characterizing treatment-naïve adolescents with AUDs but without comorbid psychopathology or polysubstance use. These results support the importance of these constructs in understanding adolescent AUDs, even when the frank externalizing diagnoses of childhood (oppositional defiant disorder and conduct disorder) are excluded.

Abstract
Adolescence is the developmental epoch during which children become adults-intellectually, physically, hormonally and socially. Brain development in critical areas is ongoing. Adolescents are risk-taking and novelty-seeking and they weigh positive experiences more heavily and negative experiences less than adults. This inherent behavioral bias can lead to risky behaviors like drug taking. Most drug addictions start during adolescence and early drug-taking is associated with an increased rate of drug abuse and dependence. The hormonal changes of puberty contribute to physical, emotional, intellectual and social changes during adolescence. These hormonal events do not just cause maturation of reproductive function and the emergence of secondary sex characteristics. They contribute to the appearance of sex differences in non-reproductive behaviors as well. Sex differences in drug use behaviors are among the latter. The male predominance in overall drug use appears by the end of adolescence, while girls develop the rapid progression from first use to dependence (telescoping) that represent a female-biased vulnerability. Sex differences in many behaviors including drug use have been attributed to social and cultural factors. A narrowing gap in drug use between adolescent boys and girls supports this thesis. However, some sex differences in addiction vulnerability reflect biologic differences in brain circuits involved in addiction. The purpose of this review is to summarize the contribution of sex differences in the function of ascending dopamine systems that are critical to reinforcement, to briefly summarize the behavioral, neurochemical and anatomical changes in brain dopaminergic functions related to addiction that occur during adolescence and to present new findings about the emergence of sex differences in dopaminergic function during adolescence.

Delineating the psychic structure of substance abuse and addictions: should anxiety, mood and impulse-control dysregulation be included? J Affect Disord 2010; 122:185-97.

Abstract
Current "official" nosology (e.g. DSM IV) is largely limited to physical manifestations of addiction that can be objectively observed and are suited to the maintaining of an "atheoretical" perspective. However, addicted subjects display additional psychiatric symptoms that affect their well-being and social functioning and, in accordance with DSM IV, are typically relegated to the domain of psychiatric "comorbidity." We contend that the relationship of these psychiatric symptoms with addiction is very close, as demonstrated by the high frequency of association observed. We further assert that substance use may modify pre-existing psychic structures such as temperament and related subthreshold conditions and lead to addiction as a specific mental disorder, inclusive also of symptoms pertaining to mood/anxiety, or impulse-control dimensions. The present contribution addresses the weaknesses of the current DSM-based nosology of addiction-related mental comorbidity. We highlight the overlap of the biological substrates and the neurophysiology of addictive processes and psychiatric symptoms associated with addiction, and propose the inclusion of specific mood, anxiety, and impulse-control dimensions in the psychopathology of addictive processes. We postulate that addiction reaches beyond the mere result of drug-elicited effects on the brain and cannot be peremptorily equated only with the use of drugs despite the adverse consequences produced. We infer that mood, anxiety and impulse-control dysregulation is at the very core of both the origins and clinical manifestations of addiction and should be incorporated into the nosology of the same, emphasising how addiction is a relapsing chronic condition in which psychiatric manifestations play a crucial role. To conclude, addictionology cannot be severed from its psychopathological connotations, in view of the undeniable presence of symptoms, of their manifest contribution to the way addicted patients feel and behave, and to the role they play in maintaining the continued use of substances.

Abstract
BACKGROUND Addiction is a relapsing chronic condition in which psychiatric phenomena play a crucial role. Psychopathological symptoms in patients with heroin addiction are generally considered to be part of the drug addict's personality, or else to be related to the presence of psychiatric comorbidity, raising doubts about whether patients with long-term abuse of opioids actually possess specific psychopathological dimensions. METHODS Using the Self-Report Symptom Inventory (SCL-90), we studied the psychopathological dimensions of 1,055 patients with heroin addiction (884 males and 171 females) aged between 16 and 59 years at the beginning of treatment, and their relationship to age, sex and duration of dependence. RESULTS A total of 150 (14.2%) patients with heroin addiction showed depressive symptomatology characterised by feelings of worthlessness and being trapped or caught; 257 (24.4%) had somatisation symptoms, 205 (19.4%) interpersonal sensitivity and psychotic symptoms, 235 (22.3%) panic symptomatology, 208 (19.7%) violence and self-aggression. These dimensions were not correlated with sex or duration of dependence. Younger patients with heroin addiction were characterised by higher scores for violence-suicide, sensitivity and panic anxiety symptomatology. Older patients with heroin addiction showed higher scores for somatisation and worthlessness-being trapped symptomatology. CONCLUSIONS This study supports the hypothesis that mood, anxiety and impulse-control dysregulation are the core of the clinical phenomenology of addiction and should be incorporated into its nosology.

Abstract
Rat studies have shown that pups subjected to suboptimal rearing conditions exhibited permanently dysregulated dopamine activity and altered behavioral responses to dopamine stimulation. In humans, heightened stress-induced mesoaccumbens dopamine release in adults reporting low maternal care experience has been shown. We explored the relationship between quality of parental care and behavioral responsivity to reward and 20 mg of the dopamine agonist methylphenidate (MPH). Forty-three male university students accomplished a monetarily rewarded card-sorting task in a placebo controlled between-subjects study design. In participants scoring above the cut-off score for high parental care as assessed by the Parental Bonding Inventory, MPH decreased performance accuracy in the reward condition of the task. Contrarily, reward-induced performance accuracy of low care participants was enhanced with MPH. Activity measures in response to reward and MPH were uninfluenced by parental care. This is the first human study to reveal that the behavioral MPH response interacts with early life parental care experience.

Abstract
OBJECTIVE This college-based questionnaire survey aimed to explore the individual, family, and peer correlates for cigarette smoking among first-year college students. METHOD The sample included 2918 first-year college students (males, 45.5%) recruited from a national university in Taiwan (participation rate, 79.1%). The participants reported on questions about various substances, attitudes toward substances, personality characteristics, psychopathology, suicidal behaviors, parenting style, family function and use of substances, and peer substance use. RESULTS There were 263 (9.0%; males, 70.6%) current smokers. Compared to nonsmokers, college smokers were more extraverted and neurotic, and showed less harm avoidance, and more novelty seeking in their personality. They had more hostile, somatic, depressive, paranoid, and psychotic symptoms in terms of psychopathology. Smokers were more likely to use other substances, and to have suicidal ideations, wishes, plans, and attempts. Smokers perceived lower family cohesion, less care from their fathers, and less overprotection from their mothers. They were more likely to have peers and family members who also smoked or used other substances. The most associated correlates were male sex, older age, other substance use, novelty seeking, suicidal ideation and attempts, sibling and peer substance use, a prosubstance attitude, and less maternal overprotection. CONCLUSIONS Our findings support the association of cigarette use in Taiwanese young adults with several individual, family, and peer factors identified in Western studies. Intervention in cigarette use should be multifaceted, by taking its correlates and the concurrent psychopathology, use of substances, and suicidality into consideration.
