Children's beliefs about substance use: An examination of age differences in implicit and explicit cognitive precursors of substance use initiation.

Cognitive models conceptualize attitudes and beliefs about substance use (SU) as proximal mediators of a variety of risk and protective factors for SU. Researchers have distinguished implicit and explicit cognition, but limited research has examined this distinction in the early stages of SU. The authors' goal was to examine age differences in implicit and explicit SU cognitions to clarify proximal cognitive processes that may be involved in early SU. Alcohol- and cigarette-naive children (N=76; 69.7% male; M age=11.8 years) completed the laboratory-based experiment. Likelihood ratings of costs and benefits of use assessed explicit cognitions, and a priming task assessed implicit cognitions. Regardless of age, children perceived costs of drinking alcohol and smoking as more likely than benefits. This discrepancy was smaller for older children, although this age difference was weaker for costs and benefits of cigarette use. Strong positive implicit alcohol use cognitions were apparent regardless of age. However, age differences were found for implicit cigarette use cognition. Older children were more positive about cigarette use. Findings suggest the importance of distinguishing explicit and implicit cognition for etiological models of early SU.

Trajectories of change in adolescent substance use and symptomatology: Impact of paternal and maternal substance use disorders.

The effects of paternal and maternal substance use disorders (SUDs) on trajectories of change in adolescent offspring nicotine, alcohol, and drug use and symptomatology were investigated in a population-based sample of adolescent twins (N = 1,514). Adolescent and parental substance phenotypes were assessed when most adolescents were 11 years old, with 2 assessments of adolescents approximately every 3 years thereafter. Growth curves were fit using hierarchical linear modeling. Results indicated acceleration of substance involvement during adolescence, particularly for boys. Paternal and maternal SUD were each associated with more extreme trajectories. There was evidence for an additive, rather than interactive, combined parental effect. Findings help clarify the impact of paternal and maternal SUD on the development of substance involvement during adolescence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Pathways from proactive and reactive aggression to substance use.

Childhood aggression is a known risk factor for adolescent substance use; however, aggression is a complex construct, and developmental researchers have identified a variety of subdimensions that may be germane to substance use. Very little research has examined risk pathways from subdimensions of aggression. The current study examined a developmental model and tested whether childhood proactive aggression, reactive aggression, or both were related to the development of substance use in adolescence in a sample of 126 children (mean age at initial assessment = 10.4 years, SD = 0.51). Peer rejection and peer delinquency were examined as potential mediators of these relations. The findings suggest that proactive aggression was indirectly associated with substance use through peer delinquency. Reactive aggression was also indirectly associated with substance use through a complex mediational chain, such that high levels of reactive aggression were associated with high levels of peer rejection, which in turn were associated with peer delinquency (p = .06), which subsequently predicted substance use.

The influence of peers on young adult substance use.

Data collected from 294 young adults, ages 19 to 25, and both a same- and an opposite-gender best friend or mate across 3 annual assessments were analyzed to examine the similarity to and influence of the peer on the young adult's substance use. The authors found similarity across time between both peers and the young adult in cigarette use, alcohol use, binge drinking, and, in most cases, marijuana use. In prospective analyses, peer use predicted young adult cigarette use, binge drinking, and problem use by the young adults. Results were generally consistent across gender and for both same- and opposite-gender peers. Findings emphasize peer influence contribution to young adult substance use and suggest the design of interventions that involve both young adults and their peers.

Sex bias in psychological research.

Sex bias occurs at different stages in research on sex differences. Review articles often attribute greater value to tasks on which good performance is more frequent among males and undervalue those tasks at which females excel. There is bias in reporting primary sources. Public statements by psychologists concerning sex differences are misleading and irresponsible. Journals more readily publish reports of sex differences and turn down reports of no differences. The conventional linguistic format describing sex differences does not adequately reflect group overlap. Research should seek to determine underlying causes for differential frequencies of good and bad performance among the sexes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Emergence of delinquency and depressed mood throughout adolescence as predictors of late adolescent problem substance use.

Delinquency is a positive predictor of adolescent problem substance use, and depressed mood may increase risk for substance problems. The extent to which effects of delinquency and depressed mood on problem substance use vary depending on when during adolescence the predictors are assessed is unknown. The authors used 5 multigroup path analyses to examine effects of delinquency and depressed mood at ages 11, 12, 13, 14, and 16 years on problem substance use at age 18, and mediation of those effects through alcohol use at age 16 across gender. Participants were 429 rural youths (222 girls and 207 boys) and their families. Indirect positive effects of delinquency on the outcome were observed for boys; direct positive effects of depressed mood were observed for girls. Prevention implications are discussed.

Age differences in resistance to peer influence.

Prior research describes the development of susceptibility to peer pressure in adolescence as following an inverted U-shaped curve, increasing during early adolescence, peaking around age 14, and declining thereafter. This pattern, however, is derived mainly from studies that specifically examined peer pressure to engage in antisocial behavior. In the present study, age differences and developmental change in resistance to peer influence were assessed using a new self-report instrument that separates susceptibility to peer pressure from willingness to engage in antisocial activity. Data from four ethnically and socioeconomically diverse samples comprising more than 3,600 males and females between the ages of 10 and 30 were pooled from one longitudinal and two cross-sectional studies. Results show that across all demographic groups, resistance to peer influences increases linearly between ages 14 and 18. In contrast, there is little evidence for growth in this capacity between ages 10 and 14 or between 18 and 30. Middle adolescence is an especially significant period for the development of the capacity to stand up for what one believes and resist the pressures of one's peers to do otherwise.

Ecological predictors of substance use in middle school students.

The current study examined important predictors of substance use during early adolescence. The authors hypothesized that adolescents' relationships with key adults (i.e., teachers and parents) influence their choices to use substances indirectly through links with their decisions regarding peer groups. A total of 461 middle school students from an affluent suburban community completed self-report measures of authoritative parenting, perceived social support from teachers, affiliation with rule-breaking and substance-using peers, and frequency of alcohol, cigarette, and drug use. Results of structural equation modeling supported the hypothesized model. Authoritative parenting and teacher support accounted for 31% of the variance in affiliation with deviant peers which, in turn, accounted for 27% of the variance in adolescent substance use; direct paths from parenting and teacher support to substance use were not indicated. Implications for school psychologists' involvement in substance use prevention and intervention are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The relation between social problems and substance use in adolescent boys: An investigation of potential moderators.

This study investigated the relation between social problems and adolescent male substance use in the context of other potential moderating variables. Two hundred eighty adolescent boys completed measures of social problems, cognitive distortions, constructive thinking, affiliation with delinquent peers, and multiple aspects of substance use. Results revealed that social problems were not directly related to most substance use variables. Cognitive distortions moderated the relation between social problems and substance use in social situations, such that the relation was significant only at high levels of cognitive distortions. Constructive thinking and affiliation with delinquent peers were both related to substance use, but neither served a moderating function. It is concluded that the widely accepted relation between social difficulties and adolescent male substance use may be better understood in the context of cognitive variables.

Developmental differences in the effects of repeated interviews and interviewer bias on young children's event memory and false reports.

The present study investigated developmental differences in the effects of repeated interviews and interviewer bias on children's memory and suggestibility. Three- and 5-year-olds were singly or repeatedly interviewed about a play event by a highly biased or control interviewer. Children interviewed once by the biased interviewer after a long delay made the most errors. Children interviewed repeatedly, regardless of interviewer bias, were more accurate and less likely to falsely claim that they played with a man. In free recall, among children questioned once after a long delay by the biased interviewer, 5-year-olds were more likely than were 3-year-olds to claim falsely that they played with a man. However, in response to direct questions, 3-year-olds were more easily manipulated into implying that they played with him. Findings suggest that interviewer bias is particularly problematic when children's memory has weakened. In contrast, repeated interviews that occur a short time after a to-be-remembered event do not necessarily increase children's errors, even when interviews include misleading questions and interviewer bias. Implications for developmental differences in memory and suggestibility are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Substance use and the paradox of good and bad attentional bias.

Habitual substance use is associated with attentional bias for stimuli related to the use. The current study tested whether individuals’ substance use can be predicted from their attentional bias for concern-related and substance-related stimuli. Participants (N = 71; 54% male) were selected among university students and the community. The study was conducted in Iran, in which alcohol consumption is illegal. Participants completed a substance use questionnaire and classic, substance-, and concern-related Stroop tests. The results show that after controlling for demographic variables and classic Stroop interference, increases in substance-related but decreases in concern-related reaction times predicted the amount of substances that had been consumed by the participants. Individuals’ attentional bias for both substance-related and substance-unrelated goals may be important in predicting substance use behavior. The implication of the findings for treatment prognosis has been discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sex differences in 2- and 3-years-olds: Mother-child relations, peer relations, and peer play.

This paper examines the different behavior patterns utilized by boys and girls as they form peer relationships and engage in peer play; the nature of their relations with their mothers is also reported. Girls manifested more intense involvement with their mothers, engaged in less peer play than boys, showed lower mood, lower levels of play, less direct aggression, and more controlling play with peers. Furthermore, their mothers handled their requests for contact and aggressive behavior differently than did mothers of boys. Boys were slower to become aware of separateness but once aware, they came to terms with it faster than girls. The boys took longer to pay attention to peers; once peers were focused on, the play moved more quickly to high levels than did the play of the girls. Qualitative findings were supported by quantitative findings-boys showed more contact and more involvement with their peers than did girls. The hypothesis is tentatively offered that the reaction to the awareness of psychological separateness from their mothers is more intense in girls than in boys partly because girls experience this awareness earlier, owing to their more rapid cognitive maturation. . .

Expectancy change and adolescents' intentions to use marijuana.

Drug prevention campaigns commonly seek to change outcome expectancies associated with substance use, but the effects of violating such expectancies are rarely considered. This study details an application of the expectancy violation framework in a real world context by investigating whether changes in marijuana expectations are associated with subsequent future marijuana intentions. A cohort of adolescents (N = 1,344; age range = 12?18 years) from the National Survey of Parents and Youth was analyzed via secondary analysis. Nonusers at baseline were assessed 1 year later. Changes in expectancies were significantly associated with changes in intentions (p     

A multiprocess account of hindsight bias in children.

In hindsight, that is, after receiving the correct answers to difficult questions, people's recall of their own prior answers tends to be biased toward the correct answers. We tested 139 participants from 3 age groups (9- and 12-year-olds and adults) in a hindsight-bias paradigm and found that all groups showed hindsight bias. Multinomial model-based analyses indicated that all age groups used the correct answers to reconstruct their original answers. In addition, the youngest group showed memory impairment caused by the presentation of the correct answers as well as an increased belief that they knew the correct answers all along. These results support a multiprocess explanation of hindsight bias in children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sibling effects on substance use in adolescence: social contagion and genetic relatedness.

Prior research on sibling contagion for substance use has not attended to individual differences in the sibling relationship that may be influenced by genetic similarity. The authors utilizing data on a sample of twin and nontwin siblings participating in the National Longitudinal Study of Adolescent Health (Add Health). Although monozygotic twins had the highest levels of sibling contact and mutual friendships, the pattern of results for other sibling types were not consistent with genetic models, and biometric analysis indicated that shared environmental factors influenced these sibling relationship features. Application of DeFries-Fulker regression models provided evidence that sibling contact and mutual friendships represent a source of social contagion for adolescent smoking and drinking independent of genetic relatedness. The results are interpreted using a social contagion framework and contrasted with other competing models such as those focused on the equal environments assumption and niche selection.

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.

A longitudinal analysis of friendships and substance use: Bidirectional influence from adolescence to adulthood.

The reciprocal relation between deviant friendships and substance use was examined from early adolescence (age 13-14) to young adulthood (age 22-23). Deviance within friendships was studied using direct observations of videotaped friendship interaction and global reports of deviant interactions with friends as well as time spent with friends. Substance use was assessed through youth self-report at all time points. Multivariate modeling revealed that substance use in young adulthood is a joint outcome of friendship influence and selection processes. In addition, substance use appears to influence the selection of friends in late adolescence. Findings suggest that effective preventions should target peer ecologies conducive to substance use and that treatment should address both the interpersonal underpinnings and addiction processes intrinsic to chronic use, dependence, and abuse.

Parents and families as contexts for the development of substance use and substance use disorders.

Parenting and familial influences on substance use and substance use disorders (SUDs) are important areas of study both for theories of etiology and for the development of preventive and treatment interventions. The articles in this special section illustrate both the value and the challenges of studying parenting and familial influences. Noteworthy issues include the need for mediational and moderational models examining the processes by which familial influences operate in a longitudinal framework to consider outcomes in a developmental context. Future directions include a multidisciplinary expansion of these studies. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A review of sex differences in peer relationship processes: Potential trade-offs for the emotional and behavioral development of girls and boys.

Theory and research on sex differences in adjustment focus largely on parental, societal, and biological influences. However, it also is important to consider how peers contribute to girls' and boys' development. This article provides a critical review of sex differences in several peer relationship processes, including behavioral and social-cognitive styles, stress and coping, and relationship provisions. The authors present a speculative peer-socialization model based on this review in which the implications of these sex differences for girls' and boys' emotional and behavioral development are considered. Central to this model is the idea that sex-linked relationship processes have costs and benefits for girls' and boys' adjustment. Finally, the authors present recent research testing certain model components and propose approaches for testing understudied aspects of the model.

A meta-analytic investigation of the relationship between attentional bias and subjective craving in substance abuse.

Theoretical models of addiction suggest that attentional bias for substance-related cues should be associated with self-reported craving. The authors evaluated the strength of the association by performing a meta-analysis on 68 independent data sets from which correlation coefficients between subjective craving and attentional bias indices were derived. Additional stratified analyses were conducted to identify any variables that might moderate the association between craving and attentional bias. The primary meta-analysis indicated a significant, albeit weak (r = .19), association between attentional bias and craving. Stratified analyses revealed that the association was larger for illicit drug and caffeine craving than for alcohol and tobacco craving, larger for direct measures of attention (eye movement measures and event-related potential measures) than for indirect behavioral measures of attentional bias, and larger when craving strength was high than when it was low (all ps
