Buffering effect of religiosity for adolescent substance use.

This research examined the hypothesis that religiosity buffers the impact of life stress on adolescent substance use. Data were from a sample of 1,182 participants surveyed on 4 occasions between 7th grade (mean age = 12.4 years) and 10th grade. Religiosity was indexed by Jessor's Value on Religion Scale (R. Jessor & S. L. Jessor, 1977). Zero-order correlations showed religiosity inversely related to alcohol, tobacco, and marijuana use. Significant Life Events×Religiosity buffer interactions were found in cross-sectional analyses for tobacco, alcohol, and marijuana use. A latent growth analysis showed that religiosity reduced the impact of life stress on initial level of substance use and on rate of growth in substance use over time. Implications for further research on religiosity and substance use are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Are work stressors related to employee substance use? The importance of temporal context assessments of alcohol and illicit drug use.

In this study, the author explored the relations of 2 work stressors (work overload and job insecurity) to employee alcohol use and illicit drug use. The primary goal was to explore the importance of temporal context (before work, during the workday, and after work) in the assessment of substance use compared with context-free (overall) assessments. Data were collected from a national sample of U.S. workers (N = 2,790) who took part in a broad cross-sectional survey on workplace health and safety. Consistent with past research, the results fail to support a relation between work stressors and overall measures of alcohol and illicit drug use. However, the results support the relation of work stressors to alcohol and illicit drug use before work, during the workday, and after work. These results provide support for both the stress-induced substance use and stress response dampening propositions of the tension-reduction hypothesis. When exploring the work environment as a potential cause of employee substance use, these results underscore the importance of measures that assess alcohol and illicit drug use in terms of their temporal relation to the workday.

Review of Alcohol and substance abuse in adolescence.

Reviews the book, Alcohol and substance abuse in adolescence edited by J. S. Brock, D. J. Lettieri, D. W. Brook, and Barry Stimmell (1985). The introductory "editorial" in this volume sets three goals which sound more like a handbook: elucidate the reasons why youth turn to drugs, how to manage those afflicted and how to educate for prevention. The papers focus largely on the first, and leave the latter two for the readers to infer. Most of the usual themes of adolescent drug use are covered: the influence of peer groups, the influence (or lack thereof) of parents, psychological development of identity and individuation. Drug use is discussed in relation to social influences, personality dynamics and adolescent development and maturation. However, the authors seem to equate any adolescent drug use (particularly marijuana) with excessive involvement. Surely it is important to examine the variations in why and how various drugs are used by that age group. It remains for others to explore the boundaries between drug use and abuse, to identify high risk patterns and to develop strategies to promote normal, healthy maturation of adolescents in a drug-drenched society.

Work-related risk factors and employee substance use: Insights from a sample of Israeli blue-collar workers.

Although studies have found evidence that certain workplace conditions in North American enterprises may serve as risk factors for alcohol and illicit drug use, little is known regarding the generalizability of these findings to enterprises in other countries. To address this gap, we collected data from a random sample of 569 blue-collar workers employed in nine different facilities of one of Israel's largest manufacturing firms. The results of zero-inflated Poisson and ordered probit regressions partly confirmed earlier findings reported in North America, with a heightened rate of a substance use among those perceiving (a) more permissive drinking norms, (b) lower supervisor ability to handle substance use problems, (c) greater exposure to job hazards, and (d) lower levels of coworker interactions. Permissive drinking norms were also found to moderate the associations between the other risk factors and substance use. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Good self-control as a buffering agent for adolescent substance use: An investigation in early adolescence with time-varying covariates.

This study tested the prediction that self-control would have buffering effects for adolescent substance use (tobacco, alcohol, and marijuana) with regard to 3 risk factors: family life events, adolescent life events, and peer substance use. Participants were a sample of public school students (N = 1,767) who were surveyed at 4 yearly intervals between 6th grade and 9th grade. Good self-control was assessed with multiple indicators (e.g., planning and problem solving). Results showed that the impact of all 3 risk factors on substance use was reduced among persons with higher scores on good self-control. Buffering was found in cross-sectional analyses with multiple regression and in longitudinal analyses in a latent growth model with time-varying covariates. Implications for addressing self-control in prevention programs are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality and performance-based measures in the prediction of alcohol use.

Research has demonstrated a variable relationship between alcohol consumption and self-report personality measures of novelty seeking and harm avoidance. Research has also demonstrated a relationship between performance-based measures of risk taking and substance use. The current study compared the utility of personality measures and performance-based measures in the prediction of alcohol use. The authors hypothesized that the domains would contribute uniquely and would also interact in the prediction of alcohol consumption. Data on alcohol consumption were collected on a daily basis for 2 weeks. Performance-based measures included the Bechara Gambling Task and the Balloon Analogue Risk Task. The Tridimensional Personality Questionnaire was the primary personality measure. Results partially supported hypotheses, in that personality measures showed strong relationships with alcohol use and interacted with performance-based measures in predicting alcohol consumption. Thus, both behavioral and personality measures contributed to prediction of alcohol consumption, and performance-based measures played a moderating role. Results suggest that a combination of behavioral and self-report personality measures may be useful for those screening groups for risk factors for excessive alcohol consumption.

Workplace substance abuse prevention and help seeking: Comparing team-oriented and informational training.

Employees fail to seek help for alcohol or drug (AOD) abuse because of unhealthy work climates, stigma, and distrust in Employee Assistance Programs (EAPs). To address such problems, the authors randomly assigned groups of municipal employees (N?=?260) to 2 types of training: a 4-hr informational review of EAPs and policy and an 8-hr training that embedded messages about AOD reduction in the context of team building and stress management. Pre- and posttraining and 6-mos follow-up surveys assessed change. Group privacy regulation, EAP trust, help seeking, and peer encouragement increased for team training. Stigma of substance users decreased for information training. EAP/policy knowledge increased for both groups. A control group showed little change. Help seeking and peer encouragement also predicted EAP utilization. Integrating both team and informational training may be the most effective for improving help seeking and EAP utilization.

The role of self-control in early escalation of substance use: A time-varying analysis.

The research tested prediction about the role of temperament and self-control in early substance use (tobacco, alcohol, and marijuana). A sample of 1,526 participants was assessed in 6th grade (mean age=11.5 yrs) and followed with yearly assessments through 9th grade. Latent growth models showed temperament dimensions were related to early substance use, and their effects were mediated through generalized self-control ability. Time-varying effects indicated rate of growth in substance use was higher among participants who showed increases in poor self-control and lower among participants who showed increases in good self-control. Results in self-report data were corroborated by independent teacher ratings. Findings are discussed with reference to epigenetic models of protection and vulnerability.

Youth crowds and substance use: The impact of perceived group norm and multiple group identification.

The impact of group identity on adolescent tobacco, alcohol, and marijuana use was examined through a postal survey. The study included adolescents who identified with 1 subgroup (n = 1425) as well as adolescents who identified with 2 (n = 895) or 3 (n = 339) subgroups. The results showed that identification with the pop, skate/hip-hop, techno, and hippie subgroups was associated with higher risks of substance use, whereas identification with the sporty, quiet, computer nerd, and religious subgroups was associated with lower risks. Perceived group norm mediated the group identity-substance use relationship. Furthermore, identification with multiple groups with corresponding norm increased norm-consistent substance use, whereas identification with multiple groups with opposing norms reduced normative behavior. Implications for health promotion are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Moderators of the relation between substance use level and problems: Test of a self-regulation model in middle adolescence.

The authors tested predictions, derived from a self-regulation model, about variables moderating the relationship between level of substance use (tobacco, alcohol, and marijuana) and problems associated with use. Data were from two independent studies of adolescents, with mean ages of 15.4 and 15.5 years (Ns=1,699 and 1,225). Factor analysis indicated correlated dimensions of control problems and conduct problems. Protective moderation was found for variables indexing good self-control; risk-enhancing moderation was found for variables indexing poor self-control. These effects were generally independent of deviance-prone attitudes and externalizing symptomatology. Multiple-group structural modeling indicated moderation occurred for paths from life stress and coping motives and for paths from level to control and conduct problems. Moderation effects were also found for parental variables, peer variables, and academic competence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Disclosure of sexual orientation and subsequent substance use and abuse among lesbian, gay, and bisexual youths: Critical role of disclosure reactions.

Research on whether disclosure of sexual orientation promotes lower substance use among lesbian, gay, and bisexual (LGB) individuals has been inconsistent. One reason for this may be that disclosure results in accepting and rejecting reactions. The current report longitudinally examines whether the types of reactions to disclosure are associated with substance use and abuse among 156 LGB youths (ages 14–21). Neither the number of disclosures nor the numbers of accepting or neutral disclosure reactions were associated with substance use or abuse. However, the number of rejecting reactions to disclosure was associated with current and subsequent alcohol, cigarette, and marijuana use, even after controlling for demographic factors, social desirability, and emotional distress. Further, accepting reactions were found to moderate or protect youths from the negative role of rejecting reactions on alcohol use, but not other substances. This research indicates that, rather than disclosure per se, it is the number of accepting and rejecting reactions in response to disclosure that are critical to understanding substance use among LGB youths. Further, the results suggest that to be maximally effective, substance use prevention and treatment efforts should address rejecting reactions.

Relation between childhood disruptive behavior disorders and substance use and dependence symptoms in young adulthood: Individuals with symptoms of attention-deficit/hyperactivity disorder are uniquely at risk.

Most prior literature examining the relations among attention-deficit/hyperactivity disorder (ADHD), conduct disorder (CD), and substance use and abuse suggests that CD fully accounts for the ADHD-substance abuse relation. This study sought to test an alternate theory that individuals with symptoms of both ADHD and CD are at a special risk for substance abuse. Relations between childhood ADHD and CD symptoms, and young adult tobacco, alcohol, marijuana, and hard drug use and dependence symptoms, were examined in a sample of 481 young adults. ADHD and CD symptoms interacted to predict marijuana dependence symptoms and hard drug use and dependence symptoms, such that individuals with high levels of both ADHD and CD had the highest levels of these outcomes.

Genetic influences on the association between personality risk factors and alcohol use and abuse.

The authors assessed the association of 2 personality dimensions with use and abuse of alcohol in 1,320 twin pairs concordantly reporting nonabstinence at age 18.5 years. The 2 alcohol outcomes differentially relate to the 2 personality dimensions: Alcohol-related problems correlate more highly with social deviance than with excitement seeking (ES), and alcohol consumption correlates more highly with ES than with social deviance. Biometric models fit to the data identified similar patterns in genetic covariance, although differences were more evident in genetic correlations between social deviance and alcohol outcomes than in those for ES. Results suggest that genetic influences underlie the association of personality with alcohol use and subsequent problems and illustrate the utility of informative twin analyses in exploring links between genes, personality, and behavior disorder.

Substance use diagnosis within a community sample of adults: Distinction, comorbidity, and progression over time.

Practicing psychologists conceptualize, assess, and treat clients who use substances in different ways. Using longitudinal data from a multiethnic community sample of 470 adults, the authors examine patterns of abuse and dependence on alcohol, marijuana, and cocaine. Men were significantly more abusive, dependent, and polysubstance dependent on all drugs than women. A large percentage of drug abusers, and over 1/3 with drug dependence, remitted without formal treatment. However, early severe problems with cocaine increased later alcohol problems. Traditional disease progression and drug use acquisition models are not supported. Psychologists should incorporate the natural course of substance use into treatment and prevention efforts.

Personality traits and the development of nicotine, alcohol, and illicit drug disorders: Prospective links from adolescence to young adulthood.

The personality traits constraint (CN) and negative emotionality (NE) have been more (CN) or less (NE) consistently associated with alcoholism. The authors examined the association of personality at age 17 with timing of onset and with prospective prediction of nicotine, alcohol, and illicit drug disorders 3 years later in a twin sample (569 females; 432 males). Earlier onset of alcohol and drug disorders (by age 17) was related to significantly lower CN compared with later onsets (by age 20); high NE was related to either onset. NE, as well as CN, uniquely predicted new onsets of all 3 types of substance use disorders by follow-up, with preexisting substance disorders taken into account. Personality traits confer generalized risk for developing any substance disorder, though some traits are more strongly linked with some substance disorders than with others.

Detection of youth at high risk for substance use disorders: A longitudinal study.

This study extends prior research (D. Clark, J. Cornelius, L. Kirisci, & R. Tarter, 2005) by determining whether variation in the developmental trajectories of liability to substance use disorder (SUD) is contributed by neurobehavioral disinhibition, parental substance use involvement, and demographic variables. The sample, participants in a long-term prospective investigation, consisted of 351 boys, evaluated at ages 10-12, 12-14, 16, 19, and 22, whose parents either had SUD or no adult psychiatric disorder. Neurobehavioral disinhibition in childhood, in conjunction with parental lifetime substance use/SUD, place the child at very high risk for SUD by age 22 if psychosocial maladjustment progresses in severity in early adolescence. These results indicate that monitoring social adjustment during the transition from childhood to mid-adolescence is important for identifying youth at very high risk for succumbing to SUD by young adulthood.

Pubertal maturation and early substance use risks among African American children.

Using 2 waves of longitudinal data collected from approximately 870 African American adolescents, this study examined (a) changes in early risk factors for substance use during transition to early adolescence, including perceived prototypes of substance-using peers, willingness and intention to use substances, number of substance-using peers, and youths' own actual substance use; (b) the relationship between pubertal timing and these substance use risks; and (c) the interaction between pubertal timing and peer substance use in predicting the risks. Results showed that, first, risks for substance use increased, particularly among girls, during the transition to early adolescence. Children's prototypic images of substance users became increasingly favorable during this transitional period; a greater number of them were willing and intended to use substances during the transition to early adolescence; and an increased number of early adolescents and their friends began to use substances. Second, these changes were significantly more likely to occur among early maturing girls. Third, early physical maturation interacted with peer substance use to affect these changes.

The relations among personality, symptoms of alcohol and marijuana abuse, and symptoms of comorbid psychopathology: Results from a community sample.

This study examined the relation of the Five-Factor Model (FFM) of personality to symptoms of alcohol and marijuana abuse before and after controlling for symptoms of antisocial personality disorder (APD) and internalizing psychopathology. The 481 participants completed a well-validated measure of the FFM and a structured diagnostic interview at age 21 years. Hierarchical regression analyses indicated that unique constellations of personality characteristics were associated with symptoms of alcohol abuse, marijuana abuse, APD, and internalizing disorders. For example, symptoms of alcohol abuse were associated with high Extraversion and low Conscientiousness, whereas symptoms of marijuana abuse were characterized by low Extraversion and high Openness to Experience. Findings have implications for models of the etiology and treatment of substance use and abuse. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mood and personality-based models of substance use.

Mood and personality-based vulnerabilities have been extensively examined in patients with substance use disorders, but their relevance as models of etiology remains to be fully investigated. The present investigation examined mood and personality-based models of substance use in a nonclinical sample of young adults. Two-hundred and twelve individuals were assessed for personality and clinical characteristics and participated in computerized ambulatory monitoring of mood states and substance use over a 1-week period. Personality factors were strong predictors of substance use frequency over the previous 30 days, as well as of substance use in daily life using ambulatory monitoring. A linear increase was also observed in the intensity of novelty seeking and antisocial personality traits as a function of the social deviance of substances used. However, mood disorder history was related only to the use of illicit drugs other than cannabis, and fluctuations in mood states did not prospectively predict daily use of substances in a manner consistent with self-medication. Moreover, there was little evidence that personality characteristics moderated relations between mood states and substance use in daily life. The relevance of results for mood and personality models of substance use etiology is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Trajectories of PTSD and substance use disorders in a longitudinal study of personality disorders.

This study investigated the co-occurrence of posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) in a sample (N = 668) recruited for personality disorders and followed longitudinally as part of the Collaborative Longitudinal Personality Disorders Study. The study both examined rates of co-occurring disorders at baseline and temporal relationships between PTSD and substance use disorders over 4 years. Subjects with a lifetime history of PTSD at baseline had significantly higher rates of SUDs (both alcohol and drug) than subjects without PTSD. Latent class growth analysis, a relatively novel approach used to analyze trajectories and identify homogeneous subgroups of participant on the basis of probabilities of PTSD and SUD over time, identified 6 classes, which were compared with respect to a set of functioning and personality variables. The most consistent differences were observed between the group that displayed low probabilities of both SUD and PTSD and the group that displayed high probabilities of both.
