Peer cluster theory and adolescent drug use: a reanalysis

Peer cluster theory hypothesizes that peer drug association has a direct effect on adolescent drug use. In turn, peer drug associations are influenced by familial factors (sanctions and strength) and individual variables (religious identification, school adjustment). Oetting and Beauvais evaluated peer cluster theory in a cross-sectional survey of 415 high school students [1]. We hypothesized, evaluated, and found support for an alternative model in which poorer school adjustment was specified as a consequence of drug use, peer drug associations, lack of family sanctions against drug use, low religious identification, and absence of family strength. This reanalysis illustrates that interpretations of structural equation modeling results from cross-sectional data are especially problematic.     

Eine neue Methode zur Untersuchung von Mikroprozessen in Lerndyaden: Eine Videostudie unter Berücksichtigung von kognitiven Grundfähigkeiten und Zielorientierungen

The study at present uses a new video method with individual audio tracks to investigate micro processes within learning in a simulation based learning setting. Visible and listenable behaviour was coded with regard to peer tutoring and problem solving. The frequencies and durations of these categories were summarized and used as dependent variables in regression models with cognitive abilities and goal orientations as predictors. Results showed that variation in the dyadic interactional behaviour was systematically related to these properties of the partners. For example, while overt problem solving behaviour is related to goal orientations there was no such effect for the cognitive abilities. Implications for the composition of dyadic learning groups and for further video study arrangements applying the new method will be discussed.     

Social signals as design interventions for enhancing citizen science contributions*

Despite the scientific potential and increasing popularity of web-based citizen science, low contribution from volunteers is often a major hurdle. Studies have shown that individual behavior could be altered through targeted design interventions, but little is known about the specific factors that modulate volunteers’ contributions. A particularly elusive question entails the role of social feedback, in the form of targeted notifications about the contribution of other volunteers. Based on social comparison theory, we hypothesized that (1) volunteers increase contribution when presented with information about a high-performing peer or group, and (2) volunteers conform more strongly to a group rather than to a single peer. To test whether volunteers’ contributions change due to the exposure to the contribution of a peer or group norm, we systematically varied the information presented to participants in an environmental monitoring citizen science project. Volunteers increased their contributions when they were presented with the contribution of a high-performing peer and norm, but they were not influenced by a low-performing peer or norm. Further, we found that volunteers were more likely to match the contributions of a group than that of a peer. However, when volunteers were simultaneously exposed to information about a peer and a group, the effect depended on the respective performance of the peer and group. A theoretical model was developed to explain volunteers’ response and dissect the specific role of social comparison. Our findings offer the possibility of increasing volunteers’ contributions through design interventions.     

Direct and Indirect Effects of Maternal and Peer Influences on Sexual Intention among Urban African American and Hispanic Females

Peer and family influences are interconnected in complex ways. These influences shape adolescent decision-making regarding engagement in sexual behaviors. Evidence indicates the more proximal (and direct) a process is to an individual, the more likely it is to affect his/her development and behavior. Therefore, family factors (e.g., parenting practices) and peer influence (e.g., peer norms) tend to be more strongly associated with adolescent behavior than distal factors (e.g., media or the economy). Guided by an ecological framework, this study explored how maternal influence variables interact with perceptions of peer influence to affect daughters’ intentions to have sex. A nonprobability sample of 176 mother–daughter dyads was recruited in clinics and service organizations in the northeastern United States. Results from path analysis revealed that maternal influence variables had a significant indirect relationship with daughters’ intentions to have sex through daughters’ perceptions of peer influence. Maternal processes can act as protective factors for adolescent girls who perceive their peers are engaged in sexual behaviors. Therefore, risk reduction interventions with adolescents should include opportunities for parents to learn about sex-related issues and develop skills that will allow them to buffer negative peer influence.     

Parenting Practices as Moderators of the Relationship Between Peers and Adolescent Marijuana Use

Using data from a probability sample of 4,987 adolescents, we examine the degree to which closeness to mother, closeness to father, parental support, and parental monitoring buffer the relationship between peer drug use and adolescent marijuana use. The relationship between peer drug use and adolescent marijuana use was attenuated by both closeness to father and the perception that parents would catch them for major rule violations. These findings confirm the value of conceptualizing certain family characteristics as separate variables and verify that authoritative parenting may help insulate adolescents from peer pressure to use drugs.     

Examining Discrimination,Ethnic‐Racial Identity Status,and Youth Public Regard Among Black,Latino, and White Adolescents

How positively adolescents believe others feel about their ethnic‐racial group (i.e., public regard) is an important part of their ethnic‐racial identity (ERI), which is likely informed by contextual and individual factors. Using cluster analyses to generate ERI statuses among Black, Latino, and White adolescents (n = 1,378), we found that associations between peer versus adult discrimination and public regard varied across ERI status and ethnic‐racial group. However, among all adolescents, an achieved ERI (i.e., having explored ethnicity‐race and having a clear sense about its personal meaning) buffered the negative association between adult discrimination and public regard, but not between peer discrimination and public regard. Implications for understanding the interplay between contextual and individual factors for public regard are discussed.     

Individual, Family, and Peer Correlates of Adolescent Gambling

The primary purpose of this study was to determine the individual, family, and peer factors that correlate with adolescent gambling. High school students from three states ( N = 1,846) completed an anonymous questionnaire assessing the behavior of themselves, their parents, and their peers. Participants also reported on their gambling behavior via the SOGS-RA, which was used to create five adolescent gambling groups (i.e., Non-Gamblers, Non-Problem Gamblers, At-Risk Gamblers, Problem Gamblers, and Probable Pathological Gamblers). In a discriminant function analysis using demographic, individual, family, and peer factors as potential discriminators, two functions emerged that accounted for 94% of the variance between groups. The first function was linear, with the Probable Pathological Gamblers reporting the highest level of peer and parent gambling, susceptibility to peer pressure, conduct problems, binge drinking, suicide attempts, drug use, and being male. The second function highlighted three unique qualities of individuals in the two outlying groups: Probable Pathological Gamblers and Non-Gamblers. These findings suggest that demographic, individual, family, and peer variables are all important correlates of probable pathological gambling in adolescents. Results also support the utility of a five-group classification scheme based on the SOGS-RA. The clinical implications of these results are discussed.     

PEER PRESSURE: EXPERIMENTAL EVIDENCE FROM RESTROOM BEHAVIOR

We provide experimental evidence on the effect of peer pressure on individual behavior. Specifically, we study the effect of being exposed to an observer in a public restroom on handwashing and urinal flushing behavior. Our estimates show that being exposed to an observer increases the probability of handwashing by 13 percentage points and the probability of urinal flushing by 15 percentage points. Given that handwashing and urinal flushing have social benefits that exceed individual benefits, our findings provide support for peer pressure as an additional way of addressing the social suboptimality arising from externalities.

Group decision-making: An economic analysis of social influence and individual difference in experimental juries

In jury decision-making, individual viewpoints must converge to reach a group consensus. Convergence of viewpoints may reflect reasonable compromises, for example if jury deliberations reflect informational influences and social learning which allow individual jurors to correct biases, misunderstandings and/or imperfect recall of evidence. Conversely, some individuals may converge towards others’ viewpoints because of normative influences including peer pressure and preferences for conformity and these can generate biases in the final jury judgements. This paper presents experimental data showing that groups do have a significant tendency to compromise in jury-like settings. Econometric evidence shows that group characteristics, including the presence of acquaintances and strangers within the jury group, affect the extent of compromise. The implications are that jury deliberations may be biased by factors not relevant to a specific case, limiting the objectivity of jury decisions.     

Peer Group Acceptance and Academic Performance Among Adolescents Participating in a Dropout Prevention Program

This investigation examines the relationship between peer group acceptance and academic performance among adolescents participating in a dropout prevention program. Three variables assessing school-related attitudes and behavior are identified as potential links between peer group acceptance and academic performance and the results are examined in the context of the gender and racial/ethnic group identification of adolescent respondents. Peer group acceptance is found to have an indirect rather than a direct influence on academic achievement. The behavior variable, avoidance of problem behavior, provides the strongest path of connection between peer group acceptance and academic performance. Implications of the findings for social work practice in the school setting are discussed.     

A covariance structure model test of antecedents of adolescent alcohol misuse and a prevention effort

As part of an alcohol misuse prevention evaluation, questionnaires were administered to 4,157 junior high school students to determine levels of alcohol misuse, exposure to peer use and misuse of alcohol, susceptibility to peer pressure, internal health locus of control, and self-esteem. A conceptual model of the antecedents of adolescent alcohol misuse and the effectiveness of a prevention effort was tested using covariance structure modeling techniques. The factor loadings for the model were all moderate to high, indicating that the observed variables served well as measurement instruments for the latent variables. The hypothesized structural relationships among the latent variables of alcohol misuse, exposure to peer use and misuse of alcohol, susceptibility to peer pressure, internal health locus of control, and self-esteem were supported by the data. The full model explained 45 percent of the variance in alcohol misuse in the analysis based on the total sample. The direct effect of the intervention on alcohol misuse was small but significant in the hypothesized direction. The direct effects of the intervention on susceptibility to peer pressure and internal health locus of control were not significant. The model was tested separately for groups of students who had high versus low scores on susceptibility to peer pressure in order to test the interaction between susceptibility to peer pressure and exposure to peer use and misuse of alcohol. The percentage of variance accounted for in alcohol misuse did not increase upon testing the model separately for students who had high versus low scores on susceptibility to peer pressure. Observed differences in the significance of the parameter estimates between the high and low susceptibility to peer pressure groups suggest that different approaches to the design and evaluation of substance abuse prevention programs may be necessary for different subgroups of students.     

A behavior genetic analysis of the tendency for youth to associate according to GPA

Behavior genetic research has revealed that many “environmental” variables are partially influenced by genetic factors. Known as gene–environment correlation (rGE), this line of scholarship provides insight on how and why individuals select into certain environments. Juxtaposing this body of evidence with research on peer group homophily—the tendency for peers to resemble one another on certain traits such as academic ability—raised two research hypotheses: (1) youth will associate with peers who receive grades similar to themselves (i.e., homophily for GPA); and (2) a portion of the variance in peer group GPA (i.e., the peer network average GPA) will be explained by individuals’ genetic self-selection into the peer group (rGE). The results supported both hypotheses by showing a strong predictive relationship between the target individual's GPA and that of his/her peers and by revealing that 72% of the variance in peer group GPA was explained by genetic influences.     

Peer cluster theory and adolescent alcohol use: an explanation of alcohol use and a comparative analysis between two causal models

This study tests the premise of peer cluster theory as it applies to individual alcohol use, and makes a comparative analysis between its ability to explain alcohol use and marijuana use. Using the results of a 1996 drug and alcohol survey of 1312 Western Kentucky University students, path analysis was used to measure the influence of six of peer cluster theory's psychosocial characteristics on the percentage of the respondent's college friends who use alcohol. All of these variables were then regressed on the respondent's alcohol use. The results of the causal models did show some support for peer cluster theory. The direct effect of the student's association with alcohol-using peers on individual alcohol use was shown to have the strongest direct influence on this outcome variable. However, a few limitations of this theoretical perspective were identified. The causal model for alcohol use showed that the indirect influence of two of these psychosocial characteristics (parental attitudes on alcohol use and success in school) was weaker than their direct influence on individual alcohol use. And, the comparative analysis showed that peer cluster theory is better suited to explain the use of marijuana than the use of alcohol.     

“I want my social worker”. One child's struggles to find an available maternal figure: reflections from a peer supervision group

In this paper, I analyse a piece of social work practice using the reflections provided by a peer supervision (work discussion) group. I describe my work with an eight year child looked after, who telephoned me stating that he wanted to kill himself. I discuss the powerful unconscious processes that contributed to his risk-taking behaviour and my emotional experience of it. I reflect on how my knowledge of psychoanalytic theory enabled me to contain the powerful feelings being projected and to safely manage the situation. I highlight how reflective peer supervision groups are a helpful way to understand the complexities of the lives of children looked after and can help inform decision making.     

GROWTH BEHIND THE MIRROR:, THE FAMILY THERAPY CONSORTIUM'S GROUP PROCESS

An earlier paper (Wendorf, 1984) presented the pragmatic aspects and theoretical model of The Family Therapy Consortium, a group set up to provide supervision and continuing education in family therapy. The emphasis was on the development of each individual therapist's competency, the isomorphic relationship between the supervisor, group, therapist, and family levels of the therapeutic system, and the legitimacy of the term "peer supervision." Beginning under the leadership of an expert supervisor hired from outside the group, the Family Therapy Consortium has developed into a peer supervision group with a "floating," rather than fixed, supervisory hierarchy. The present paper charts this development and explores the peer supervision process as it currently works in the Consortium. The focus is on the growth of the individual behind the mirror as therapist, person, leader and group member, and on the growth of the group as a "mature sibling subsystem" no longer in need of outside supervision. Individual and group development are seen as complementary aspects of the same growth process.     

Driving Under the Influence of Risky Peers: An Experimental Study of Adolescent Risk Taking

Both passive and active social influences may affect adolescents' dangerous driving. In this study, we used an experimental paradigm to delineate these two influences with actual peers. Adolescents completed a simulated driving task, and we measured risk preferences of each member of the peer group. We used hierarchical linear modeling to partition variance in risky decisions. Adolescents experienced many more crashes when they had “passengers” present who reported a strong preference for risk taking and who actively provided decision‐making guidance. Although youth in the passive peer condition were also influenced by the riskiness of their peers, this relation was less strong relative to the active condition. We discuss the need for interventions focussing on active and passive peer influence.     

Individual indicators of self-reported victimization among elementary school-age students: A latent class analysis

Peer victimization, in physical, verbal, or relational forms, can lead to significant developmental challenges with up to 60% of children being exposed to victimization during elementary school. Few studies to date have used person-centered approaches to understand this problem among elementary school samples. The present study aimed to investigate peer victimization exposure using Latent Class Analysis among a sample of 3^rd–5^th grade students and to examine differences in individual level characteristics among classes. From the analysis, three classes emerged including a non-victimized, a generally victimized, and a relationally victimized class. Students in the generally victimized class evidenced the worst individual outcomes. These results suggest that early intervention with peer victimization may help to mitigate negative developmental impacts for those victimized by multiple forms and universal and targeted interventions may be particularly useful for this age group.     

Individual treatment of intimate partner violence perpetrators

This article outlines a rationale for investigating the individual (one-on-one) treatment format and individualized (case-tailored) services for partner abuse perpetrators. Many state standards caution against or prohibit individual services in abuser intervention. However, initial research indicates that motivational interviewing, conducted individually, can increase abusive clients' engagement in the change process. Challenges of using the group format in treatment development are discussed along with potential benefits of individual treatment for this population. Notably, individual treatment can be adapted to the client's stage of change, can address a range of presenting concerns (such as substance abuse and mood disorders) that may influence outcome, and can be used to focus clinical attention on case-specific change targets while avoiding potentially negative and antisocial peer influences in the group format. Nevertheless, individual treatment has been almost entirely ignored to date in clinical research with this population.     

An evaluation of prototype school-based peer counseling program.

This study reports short-term outcome evaluation results of a school-based peer counseling (PRC) program as implemented by North Forsyth High School during January 1990-February 1991. The PRC program is evaluated in terms of: 1) the content of the program as evaluated by the PRC trainees; 2) the quality of the PRC instructor as perceived by these trainees; 3) several instrumental objectives deduced from the PRC training program; and 4) the degree to which the program was able to reach other students at North Forsyth during the time the PRC was in operation. In the absence of a control group, the treatment effect of the program is determined in terms of individual growth curve models. Through the multiple evaluation designs employed in this research, it has been learned that a significantly larger proportion of students in the PRC group had more favorable attitude toward the content of the PRC program when compared to the content of what they learned from their regular school curricula. Furthermore, a significantly larger proportion of students in the PRC program reported more favorable attitude toward their instructor than their regular school teachers. The PRC program was able to elicit an improvement of trainee self-esteem (p less than .01) and their social values (p less than .05) between pre and post of the Peer Training Evaluation Instrument. In terms of client access, 18.4 percent of the totality of potential clients at North Forsyth have been reached through sixty-one peer counselors sanctioned by the school.     

The persistence of variation in individual grammars: Copula absence in ‘urban sojourners’ and their stay‐at‐home peers,Bequia (St Vincent and the Grenadines)1

Recent work on phonological variation largely supports the apparent‐time construct, though some change across an individual's lifespan is possible. But how much change is possible in an individual's grammar? How much is grammar affected by extended absence in a new, urban speech community? Social dialect surveys traditionally exclude individuals who have left their community for an extended period of time, under the assumption that dialect contact causes levelling or restructuring of the linguistic system. However, our ongoing work in a Caribbean speech community suggests that the kinds of changes that can affect grammatical variables are more constrained than we might think. Raw frequencies of vernacular variants may fluctuate, but language‐internal constraints persist. Drawing on recordings from Bequia we compare the group norms for absence of copula/auxiliary be in three villages. We show that ‘urban sojourners’– Bequians who have spent an extended period overseas – may sound very different from their stay‐at‐home peers, but close examination shows only superficial restructuring of their grammars. Overall frequencies of be absence may be dramatically reduced but the ranking of language‐internal constraints remains largely unchanged. These results reaffirm the validity of modelling variable rules in a community grammar, rather than as an aggregation of idiolectal norms.
