“You See It Everywhere. It’s Just Natural.”: Contextualizing the Role of Peers,Family, and Neighborhood in Initial Substance Use

The current study utilizes in-depth interviews with inner city African-American and Latino adolescents to understand how they negotiate initial substance use. We applied the social norms approach to explore the role of peers, family, and neighborhood on adolescents’ initial substance use. Utilizing data from 36 interview participants, our analysis revealed that extended family members were pivotal in providing adolescents with their initial alcohol; however, female adolescents were more likely than male adolescents to acquire marijuana from their male peers, for free. Understanding situational contexts underlying initial substance use is imperative for future interventions with this population.     

Predictors and outcomes of cyberbullying among college students: A two wave study

Existing research on cyberbullying has primarily focused on adolescents in cross-sectional survey studies, with less research focusing on college students or employed adults over longer periods of time. To extend this literature, the current study examined new predictors and outcomes of cyberbullying perpetration (CP) and victimization (CV) among college students from two different universities that were followed across two time points. Risk factors were measured in line with previous theoretical models, including biological or personality-related variables (e.g., low self-control, dark-side personality traits, empathy) and environmental variables (e.g., perceived social support, lack of rule clarity, and internet use). Additionally, we examined several possible outcomes of CV and CP. Results from path analyses revealed that involvement with traditional bullying (either as a perpetrator or a victim) as well as Machiavellianism significantly predicted CV and CP. With regard to the cross-lagged associations between CV and CP, we found that Time 1 CV predicted time 2 CP, but Time 1 CP did not predict Time 2 CV. That is, being a victim of cyberbullying during the Fall semester predicted involvement as a perpetrator in the Spring semester. However, being a perpetrator during the Fall semester did not predict being a victim during the Spring semester. Regarding outcomes, we found that CV significantly predicted anxiety, depression, and helping behavior, and CP significantly predicted deviant behavior, but not GPA nor alcohol consumption. These findings have practical implications for college students as well as university student support services.     

Use of the MMPI-2 in American Indians: II. Empirical correlates

R. W. Robin, R. L. Greene, B. Albaugh, A. Caldwell, and D. Goldman (2003) reported that members of 2 American Indian tribal groups had statistically significant higher T scores on several MMPI-2 clinical, content, and supplementary scales than did the MMPI-2 normative group. The present study investigated the empirical correlates of the MMPI-2 scales in these American Indian tribal members. There were a large number of significant correlates reflecting antisocial symptoms with Scales 4 (Psychopathic Deviate), 9 (Hypomania), Anger, and Antisocial Practices. There were even a larger number of significant correlates reflecting generalized distress and negative affect with Scales 7 (Psychosthenia), 8 (Schizophrenia), Anxiety, Obsessions, Depression, and Welsh Anxiety. The rationally derived MMPI-2 content scales generally had larger correlations with these constructs than the clinical scales. Thus, the differences reported by R. W. Robin et al. (2003), appear to reflect behaviors and symptoms that American Indians participants were experiencing rather than test bias.     

Correlates of attitudes toward sexual harassment among early adolescents

A survey of 458 early adolescents (87% White; 278 females and 280 males; Mage = 13) examined the interacting relationship between family environment and involvement with pop music, and attitudes toward sexual harassment, while also controlling for sex. Attitudes toward sexual harassment were assessed by an eight-item Likert-type scale constructed from common behavioral definitions of sexual harassment (reliability alpha = .89). Results indicated females held less accepting attitudes toward sexual harassment than males. Involvement with pop music was associated with acceptance of sexual harassment, especially for females. The combination of a high level of exposure to pop music videos, and being from an unsatisfactory or nonintact family, was strongly associated with acceptance of sexual harassment for females and less so for males. The findings of this study could have implications for the etiology of acceptance of other coercive behaviors among adults.

     

Cognitive Theories of Depression in Children and Adolescents: A Conceptual and Quantitative Review

This paper quantitatively reviews longitudinal studies examining three central cognitive theories of depression—Beck’s theory, Hopelessness theory, and the Response Styles theory—among children (age 8–12) and adolescents (age 13–19). We examine the effect sizes in 20 longitudinal studies, which investigated the relation between the cognitive vulnerability–stress interaction and its association with prospective elevations in depression after controlling for initial levels of depressive symptoms. The results of this review suggest that across theories there is a small relation between the vulnerability–stress interaction and elevations in depression among children (pr = 0.15) and a moderately larger effect (pr = 0.22) among adolescents. Despite these important findings, understanding their implications has been obscured by critical methodological, statistical, and theoretical limitations that bear on cognitive theories of depression. The evidence base has been limited by poor measurement of cognitive vulnerabilities and over reliance on null hypothesis significance testing; these have contributed to a field with many gaps and inconsistencies. The relative paucity of research on developmental applications of such theories reveals that surprisingly little is known about their hypothesized etiologic mechanisms in children and adolescents. Ways to advance knowledge in the area of cognitive theories of depression among youth are discussed.     

Systematic and heuristic processing of majority and minority-endorsed messages: the effects of varying outcome relevance and levels of orientation on attitude and message processing

Two experiments investigated the conditions under which majority and minority sources instigate systematic processing of their messages. Both experiments crossed source status (majority vs. minority) with message quality (strong vs. weak arguments). In each experiment, message elaboration was manipulated by varying either motivational (outcome relevance, Experiment 1) or cognitive (orientating tasks, Experiment 2) factors. The results showed that when either motivational or cognitive factors encouraged low message elaboration, there was heuristic acceptance of the majority position without detailed message processing. When the level of message elaboration was intermediate, there was message processing only for the minority source. Finally, when message elaboration was high, there was message processing for both source conditions. These results show that majority and minority influence is sensitive to motivational and cognitive factors that constrain or enhance message elaboration and that both sources can lead to systematic processing under specific circumstances.     

Evidence for criterion shifts in visual perceptual learning: data and implications

Work on visual perceptual learning for contrast detection has shown that reliable decreases in detection thresholds are accompanied by reliable increases in false alarm rates (Wenger & Rasche, 2006). The present study assesses the robustness and replicability of these changes, demonstrating that they are independent of a variety of task demands (i.e., the specific method used for perceptual practice and threshold estimation) and the presence or absence of trial-by-trial feedback and that the source of the increases can be found in shifts in changes in sensitivity and in bias for detection, identification, or both. Although the increase in false alarm rates suggests a strategic shift in response criteria for detection, we demonstrate that there are multiple potential explanations, including explanations that do not require strategic shifts on the part of the observer. The empirical evidence and analysis of alternative explanations reinforce the inference that visual perceptual learning may involve more than changes in perceptual sensitivity and that cortical circuits beyond the primary visual areas may be involved.     

Adolescent Diabetic Control: Using the Process‐Person‐Context‐Time Model

This investigation used the Process‐Person‐Context‐Time Model (U. Bronfenbrenner, 1979, 1995) to study adolescent diabetic control. The dependent variable was a blood test measuring diabetic control (i.e., HbA1 C [glycosylated hemoglobin]). Independent variables included adolescent/maternal perceptions of family environment and communication, blood glucose monitoring frequency, age of disease onset, disease duration, race/ethnicity, gender, and mother's education level. Stepwise regression revealed that glucose monitoring and problem communication explained 17% of the variance.     

Between reasoning

In two experiments we investigated three-term reasoning with spatial relational assertions using the preposition between as compared to projective prepositions (such as to the left of). For each kind of assertion we distinguish the referent expression (i.e., the grammatical subject) from the relatum expression (i.e., the internal argument of the preposition; e.g., [The hedgehog]_{referent_expression} is to the left of [the frog]_{relatum_expression}; [the snake]_{referent_expression} is between [the donkey and the deer]_{relatum_expression}). Previous research has shown that integrating premises with projective prepositions is easier (a) when the relatum expression of the second premise denotes an element already given by the first premise (relatum = given), and (b) when the term denoting a given element precedes the term denoting a new element (given-new). Experiment 1 extended this finding to second premises with the preposition between. In Experiment 2, between figured in the first premise. In this case, participants built an initial preferred model already from the first premise, although such a premise is indeterminate with respect to the array that it describes. Since there is no need left for integrating the second premise, this premise is instead used to verify the initial model and to modify it when necessary. A further investigation of conclusion evaluation times showed that conclusions were evaluated faster when they first mentioned the element that was included most recently into the mental model of the premises. The use of premises with between permitted the separation of recency of model inclusion from recency of appearance of an element in a premise.
