Peer drug associations and emotional restraint: Causes or consequences of adolescents' drug use?

A 3-wave longitudinal design was used to examine the relationships among emotional restraint, peer drug associations, and gateway drug use in a sample of 1,256 middle school students. Structural equation modeling was used to compare 3 models: (1) One model viewed drug use as a consequence of emotional restraint and peer variables; (2) 1 viewed drug use as a cause of restraint and peer variables; and (3) 1 included reciprocal effects. All 3 models fit the data fairly well. However, the reciprocal model fit the data significantly better than either of the others. Within this model, low emotional restraint was significantly related to subsequent increases in gateway drug use among boys. In contrast, peer drug models and peer pressure were not related to subsequent changes in gateway drug use. Changes in peer drug models were, however, predicted by previous levels of gateway drug use. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Peer influences and drug use among urban adolescents: Family structure and parent–adolescent relationship as protective factors.

The moderating influences of family structure and parent–adolescent distress on the relationship between peer variables and drug use were examined in a predominantly African American sample of 630 10th graders at 9 urban high schools. Both peer pressure and peer drug use were significantly related to the reported frequency of drug use. The relationship between peer pressure and drug use was stronger among girls than boys, and also among adolescents in families without fathers or stepfathers. The association between peer pressure and drug use also increased as a function of the level of mother–adolescent distress among adolescents who were not living with fathers or stepfathers. Neither gender nor family structure moderated the relationship between peer drug models and drug use. However, the association between peer drug models and drug use increased as a function of the level of mother–adolescent distress. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Peer cluster theory, socialization characteristics, and adolescent drug use: A path analysis.

A new psychosocial model, peer cluster theory, suggests that the socialization factors that accompany adolescent development interact to produce peer clusters that encourage drug involvement or provide sanctions against drug use. These peer clusters are small, very cohesive groupings that shape a great deal of adolescent behavior, including drug use. Peer cluster theory suggests that other socialization variables, strength of the family, family sanctions against drug use, religious identification, and school adjustment influence drug use only indirectly, through their effect on peer clusters. Correlations of these socialization variables with drug use confirm the importance of socialization characteristics as underlying factors in drug use and also confirm that other socialization factors influence drug use through their effect on peer drug associations. Peer cluster theory suggest that treatment of the drug-abusing youth must alter the influence of the peer cluster or it is likely to fail. Prevention programs aimed at the family, school, or religion must also influence peer clusters, or drug use will probably not be reduced.

Cost-effectiveness of preoperative sestamibi scan for primary hyperparathyroidism is dependent solely upon the surgeon''s choice of operative procedure

Identified and developed a scale to assess problematic interpersonal situations among urban adolescents. In Study 1, problematic situations were identified by focus groups of 6th graders (N = 43). Their relevance was verified in Study 2 by assessing their reported frequency and difficulty in a sample of 6th graders (N = 457) that included mostly African American youth from low-income families. Scales representing 3 dimensions, peer provocation, perceived injustice, and environmental stressors were verified by confirmatory factor analyses. In Study 3, the internal consistency and structure of these scales were cross-validated in a sample of 7th graders (N = 459). All 3 scales were correlated with self-reported violent behavior, drug use, and anxiety and uniquely accounted for 11% to 19% of the variance. These findings have implications for identifying youth at risk for emotional and behavioral problems and for designing more relevant interventions.     

Laser-Doppler flowmetry in neurosurgery

It is theorized that persons with strong sense of coherence are likely to define an event as less stressful and be able to manage a problem more successfully than those with weak sense of coherence. The study investigated the relationship among coherence and personal and environmental concerns, appraisal of threat, emotional distress, and high-risk behaviors in minority women at risk for human immunodeficiency (HIV) infection. As predicted, a significant negative relationship was seen between level of coherence and concerns. Moreover, women strong in coherence reported less negative appraisals of threat, less emotional distress, and fewer high-risk behaviors than those with weak coherence. Results of tests of a path model investigating the impact of coherence and appraisal on distress and risk revealed coherence to be significantly and negatively associated with appraisal, distress, and risk, both directly and indirectly through its association with appraisal. The path model accounted for 45% of the variance in distress, 10% of the variance in appraisal, and 4% of risk behavior. Continuing investigation of factors such as coherence that can lessen the seriousness of environmental stressors is imperative as it relates to women at risk for HIV infection.     

Perceptions of peer pressure, peer conformity dispositions, and self-reported behavior among adolescents.

Two samples, consisting of a total of 1,027 6th–12th graders from separate communities, were given measures of peer conformity dispositions (willingness to accede to peer pressure), perceptions of peer pressure, and self-reported frequency of behavior concerning 2 major aspects of teenage life: peer involvement (degree of socializing with friends) and misconduct (drug/alcohol use, sexual intercourse, and minor delinquent behavior). Results indicate that Ss perceived less peer pressure toward misconduct than peer involvement and also were comparatively less willing to follow peers in misconduct. Nevertheless, perceived peer pressure and conformity disposition accounted for more of the variance in self-reported misconduct than in self-reported peer involvement. Age differences were modest and varied among measures and samples. The samples also differed in the magnitude of perceived pressures and conformity dispositions as well as in the degree to which these variables were associated with self-reported behavior. It is concluded that the findings reveal a complexity in adolescent conformity that bears elaboration in future research. (31 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Emotional Distress in Nonmetropolitan Persons Living With HIV Disease Enrolled in a Telephone-Delivered, Coping Improvement Group Intervention.

The study delineated depressive symptoms and modeled emotional distress in persons living with HIV disease in nonmetropolitan areas of 13 U.S. states. Participants (N=329) were enrolled in a randomized clinical trial of a telephone-delivered, coping improvement group intervention, and 60% reported moderate or severe levels of depressive symptomatology on the Beck Depression Inventory. Structural equation modeling indicated that participants who experienced more severe HIV symptomatology, received less social support, and engaged in more avoidant coping also experienced more emotional distress (a latent construct comprising depressive symptoms and emotional well-being). Greater HIV-related stigma and rejection by family led to more emotional distress, with social support and avoidant coping mediating almost entirely the effects of the former 2 variables. The model accounted for 72% of the variance in emotional distress in nonmetropolitan persons living with HIV disease. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

How well does number of parents explain unique variance in self-reported drug use?

Data from an anonymous survey of 3,690 adolescents were used to assess how much of the unique variance in adolescents' self-reported drug use was accounted for by number of parents in comparison to the adolescents' sex, age, social class, and peer drug use. Multiple regression revealed that the contribution of number of parents was small and nonsignificant compared to peer use, student age, parental occupation and remarriage, student sex, and parental unemployment.

The role of differentiation of self in marital adjustment.

In the present investigation, Murray Bowen's (1978) theoretical propositions about the relationship between differentiation of self and quality of marital relationships were tested. Couples' levels of differentiation explained substantial variance in marital adjustment: 74% of variance in husband marital adjustment scores and 61 % of variance in wife marital adjustment scores were accounted for by couple differentiation of self-scores. Greater husband emotional cutoff uniquely accounted for husband and wife marital discord. Contrary to family systems theory, actual couples were no more similar on differentiation than were randomly matched couples. Finally, greater complementarity among couples along the specific dimensions of emotional cutoff and emotional reactivity predicted greater marital distress.

Effects of psychosocial and situational variables on substance abuse among homeless adults.

Finding direct and indirect influences of salient psychosocial and situational variables on problem substance use among homeless people is important in designing evidence-based, effective, and relevant interventions for this special population. A stress-coping paradigm in conjunction with situational items specialized for homeless people was used to explore predictive relationships in a sample of homeless adults (N = 664) among (a) psychosocial variables of self-esteem, social support, positive and negative coping, and emotional distress, (b) situational variables of homelessness history and quality of recent housing, and (c) outcomes of alcohol use, injection drug use (IDU), and non-IDU. Lower self-esteem predicted greater emotional distress, lower positive coping, greater negative coping, and more alcohol use. Social support predicted less emotional distress and more positive coping. Chronic homelessness predicted more emotional distress, less positive coping, greater alcohol use, and IDU. Poor housing was associated with more alcohol use and IDU. Substance abuse interventions among the homeless should have a dual focus that includes attention to psychological issues and negative coping patterns while also addressing situational, environmental factors, including encouraging provision of permanent supportive housing.

Effects of ratee task performance and interpersonal factors on supervisor and peer performance ratings.

The study examines the effects of a wide array of rater–ratee relationship and ratee-characteristic variables on supervisor and peer job-performance ratings. Interpersonal ratings, job performance ratings, and ratee scores on ability, job knowledge, and technical proficiency were available for 493 to 631 first-tour US Army soldiers. Results of supervisor and peer ratings-path models showed ratee ability, knowledge, and proficiency accounted for 13% of the variance in supervisor performance ratings and 7% for the peer ratings. Among the interpersonal variables, ratee dependability had the strongest effect for both models. Ratee friendliness and likability had little effect on the performance ratings. Inclusion of the interpersonal factors increased the variance accounted for in the ratings to 28% and 19%, respectively. Discussion focuses on the relative contribution of ratee technical and contextual performance to raters' judgments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The mental health costs and benefits of giving social support.

Is giving support neutral, beneficial or costly to mental health? The authors identified 2 types of support--companionship and help--and conceptualized their provision as emotional labor. Companionship involves showing care to people, building feelings of happiness, pride, and belonging, whereas help involves assisting with feelings of distress, anger, and conflict and is potentially much more stressful. Using survey data (N=398), the authors found that companionship and help showed opposite associations with support givers' mental health; companionship was associated with fewer depressive symptoms, whereas help was associated with more. Social support helps recipients cope with stress and distress, but it may also affect people who give it, with consequences depending on the type of support given.

Touch relieves stress and pain

The contribution of non-biomedical factors to the experience of pain in the cancer patient has not been well established. Although intensity of pain reports cannot be fully explained by extent of identifiable nociception or neuropathy, behavioral factors have been only modest predictors of cancer pain report. Most studies that have demonstrated associations between pain and behavioral factors were conducted with highly selected groups of patients with all data collected concurrently. Thus the predictive value of the behavioral factors has been indeterminable. In this study, 358 bone marrow transplant patients (196 male, 162 female) completed pretransplant biomedical, physical functioning, psychological and social evaluations. For 25 days following transplantation, patients completed daily visual analogue scale oral pain reports and nurses recorded opioid use. At least once a week oral medicine staff completed a standardized, validated measure of observable oral mucositis as a measure of nociception. Results indicated that psychological and social variables were significant predictors of pain in this sample. Distress, particularly distress specific to the transplant, was the strongest predictor, while self-efficacy and coping style were weaker, but significantly associated with pain report for either men or women. While the psychological and social variables were significant predictors of pain, most of the variance in pain report was explained by biomedical variables rather than psychological or social variables. These results are consistent with those of previous research and indicate that biopsychosocial associations predate the onset of pain, but are at best modest predictors of cancer patients who will report greater or lesser pain. Clinical applications and limits of these data are discussed, particularly in relation to emotional distress, coping style and the differences found in predicting pain in men and women.     

Multivariate models of mothers' and fathers' aggression toward their children.

Multivariate, biopsychosocial, explanatory models of mothers' and fathers' psychological and physical aggression toward their 3- to 7-year-old children were fitted and cross-validated in 453 representatively sampled families. Models explaining mothers' and fathers' aggression were substantially similar. Surprisingly, many variables identified as risk factors in the parental aggression and physical child abuse literatures, such as income, unrealistic expectations, and alcohol problems, although correlated with aggression bivariately, did not contribute uniquely to the models. In contrast, a small number of variables (i.e., child responsible attributions, overreactive discipline style, anger expression, and attitudes approving of aggression) appeared to be important pathways to parent aggression, mediating the effects of more distal risk factors. Models accounted for a moderate proportion of the variance in aggression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Identifying Shared Environmental Contributions to Early Substance Use: The Respective Roles of Peers and Parents.

Although behavior genetic studies have suggested that early substance use is primarily environmentally mediated, no study has sought to identify the specific sources of environmental variance. Using data obtained from multiple informants, this study assessed the contributions of peer deviance and parent-child relationship problems to substance use in 14-year-old male and female twins (N = 1,403) drawn from the Minnesota Twin Family Study (MTFS). All three phenotypes were influenced primarily by shared environmental variance (average c2 = .51), as was the overlap among them. Moreover, peer deviance and parent-child relationship problems accounted for approximately 77% of the variance in early substance use. Findings also indicated that peer deviance, but not parent-child relationship problems, accounted uniquely for variance in early substance use.

Emotional processing in experiential therapy: Why "the only way out is through."

The purpose of this study was to examine observable moment-by-moment steps in emotional processing as they occurred within productive sessions of experiential therapy. Global distress was identified as an unprocessed emotion with high arousal and low meaningfulness. The investigation consisted of 2 studies as part of a task analysis that examined clients processing distress in live video-recorded therapy sessions. Clients in both studies were adults in experiential therapy for depression and ongoing interpersonal problems. Study 1 was the discovery-oriented phase of task analysis, which intensively examined 6 examples of global distress. The qualitative findings produced a model showing: global distress, fear, shame, and aggressive anger as undifferentiated and insufficiently processed emotions; the articulation of needs and negative self-evaluations as a pivotal step in change; and assertive anger, self-soothing, hurt, and grief as states of advanced processing. Study 2 tested the model using a sample of 34 clients in global distress. A multivariate analysis of variance showed that the model of emotional processing predicted positive in-session effects, and bootstrapping analyses were used to demonstrate that distinct emotions emerged moment by moment in predicted sequential patterns.

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)     

Like father, like son? Predicting male adolescents' adjustment from parents' distress and self-restraint.

Mothers' and fathers' own subjective distress and self-restraint when their sons were preadolescents were related to 14 measures of sons' outcomes 4 yrs later. A sample of 82 adolescent boys, including 55 from 2-parent families, participated. Consistent with expectations, the sons of fathers prone to low self-restraint uniformly had subsequent difficulties across domains, including poor academic achievement (e.g., low grades, truancy), poor peer relations (e.g., low emotional support and intimacy), at-risk behaviors (e.g., drug and alcohol use, multiple sexual partners, poor conflict resolution skills), and adjustment problems (e.g., symptoms of depression). In 2-parent families, the associations between mothers' adjustment and sons' outcomes became nonsignificant once differences in fathers' self-restraint were taken into account.
