Juvenile offenders suffer from substance use disorders at higher rates than adolescents in the general public. Substance use disorders also predict an increased risk for re-offending. Therefore, it is important that these juveniles, in particular, receive the appropriate substance use disorder treatment. The present study used logistic regression to test whether race/ethnicity would moderate the match between substance use disorder diagnosis and the receipt of a substance use disorder related service in a sample of male, serious juvenile offenders. Results showed that among those with a substance use disorder diagnosis, there were no race/ethnicity differences in the receipt of the appropriate service. However, among those without a substance use disorder diagnosis, non-Hispanic Caucasians were more likely to receive substance use service than were Hispanics or African-Americans. Post-hoc analyses revealed that when using a broader definition of substance use problems, significant differences by race/ethnicity in the prediction of service receipt were only observed at low levels of substance use problems. These findings shed light on how race/ethnicity may play a role in the recommendation of substance use disorder services in the juvenile justice system.

Anxiety and depression are among the most prevalent disorders in youth, with prevalence rates ranging from 15% to 25% for anxiety and 5% to 14% for depression. Anxiety and depressive disorders cause significant impairment, fail to spontaneously remit, and have been prospectively linked to problematic substance use and legal problems in adulthood. These disorders often share a high-degree of comorbidity in both clinical and community samples, with anxiety disorders typically preceding the onset of depression. Given the nature and consequences of anxiety and depressive disorders, a plethora of treatment and preventative interventions have been developed and tested with data showing significant pre to post to follow-up reductions in anxiety and depressive symptoms. However, little is known about the mediators by which these interventions achieve their effects. To address this gap in the literature, the present thesis study combined meta-analytic methods and path analysis to evaluate the effects of youth anxiety and depression interventions on outcomes and four theory-driven mediators using data from 55 randomized controlled trials (N = 11,413). The mediators included: (1) information-processing biases, (2) coping strategies, (3) social competence, and (4) physiological hyperarousal. Meta-analytic results showed that treatment and preventative interventions reliably produced moderate effect sizes on outcomes and three of the four mediators (information-processing biases, coping strategies, social competence). Most importantly, findings from the path analysis showed that changes in information-processing biases and coping strategies consistently mediated changes in outcomes for anxiety and depression at both levels of intervention, whereas gains in social competence and reductions in physiological hyperarousal did not emerge as significant mediators. Knowledge of the mediators underlying intervention effects is important because they can refine testable models of treatment and prevention efforts and identify which anxiety and depression components need to be packaged or strengthened to maximize intervention effects. Allocating additional resources to significant mediators has the potential to reduce costs associated with adopting and implementing evidence-based interventions and improve dissemination and sustainability in real-world settings, thus setting the stage to be more readily integrated into clinical and non-clinical settings on a large scale.

Ethnic enclaves, or neighborhoods with high ethnic densities, have been linked with positive health outcomes and lower crime rates. Using data from the Pathways to Desistance project, this study tested whether neighborhood Latino concentration prospectively predicted re-offense rates among a sample of Mexican American juvenile offenders (n = 247). Further, I tested whether the effect of neighborhood Latino concentration on re-offense was moderated by ethnic identity, Mexican orientation, and generation status. Covariates included demographics and risk factors for offending. Results showed that neighborhood Latino concentration, ethnic identity, Mexican orientation, and generation status were not predictive of re-offense rates. Gender, risk for offending, and time spent supervised during the follow-up period predicted re-offense rates one year later. The results highlight the importance of risk assessment for this high risk group.

Social Networking Sites (SNSs), such as Facebook and Twitter, have continued to gain popularity worldwide. Previous research has shown differences in online behaviors at the cultural level, namely between predominantly independent societies, such as the United States, and predominantly interdependent societies, such as China and Japan. In the current study I sought to test whether self-construal was correlated with different ways of using SNSs and whether there might be SES differences within the US that were analogous to previously observed cross-cultural differences in SNS use. Higher levels of interdependence were linked with using SNSs to keep in touch with family and friends, and providing social support to others. Interdependence was also correlated with Facebook addiction scale scores, using SNSs in inappropriate situations, and overall SNS use. Implications for assessing risk for Internet addiction, as well as understanding cultural variations in prevalence of Internet addiction are discussed.

A prior experiment by Li and colleagues found that when participants rated same sex faces in physical attractiveness, their self-reports of religiosity were higher in comparison to those that rated opposite sex faces. Could this be due to participants feeling their sexuality was threatened or misunderstood? In the current experiment, we attempted to replicate these findings and extend them by using a pseudo personality test that presented false feedback to participants. This feedback explained that their personalities were similar to homosexual or heterosexual people. Four hundred and fifty participants from Amazon Mturk were randomized into these conditions. We also measured homophobia, moral values, and the believability of the experiment. Results displayed no replication of the original findings. Men were more homophobic than women, while displaying lower moral values and religiosity. Those that self-reported being more homophobic also reported being more religious and moral. In conditions of sexual threat (homosexual personality, same sex faces) and sexual comfort (heterosexual personality, opposite sex faces), self-reports of moral values increased. Participants that reported believing the feedback displayed higher religiosity in both sexual threat and sexual comfort conditions. For a more concrete understanding of the relationship between religiosity, mating goals, and threats to sexuality, more research needs to be performed.

Previous studies exploring variability in sentencing decisions have consistently found gender differences, such that women receive lighter sentences than men. In the proposed study, I present a new framework for understanding gender differences in sentencing preferences, including circumstances under which no gender differences should emerge. The Affordance Management Approach suggests that our minds are attuned to both group- and individual-level threats and opportunities that others afford us. I conceptualize the sentencing difference between men and women as driven by perceived affordances that assist or hinder an individual in achieving certain fundamental goals. When faced with sanctioning an offender in our community, the offender's sex, the victim's age, and environmental variables such as the ratio of men to women may influence our decision-making, because these factors have affordance implications. Thus, I hypothesized that individuals will express differences in the sentencing of offenders who commit assault, and that these differences vary by offender sex, victim age, and sex-ratio. The results indicate that, as predicted, female offenders received lighter sentencing than men when the offender committed an assault against a same-sex adult, but received equally punitive sentences as men when the assault was committed against a child. In general, results do not support a consistent effect of sex ratio as a factor when making sentencing decisions. Although results do not fully support the current study's specific hypotheses, there remains much to be gained from applying an affordance management perspective to understanding variability in sentencing between the sexes.

The purpose of this study was to expand on existing parental socialization models of youth achievement motivation for engaging in physical activity. This study examined the extent to which youth affective reactions and expectancy-value beliefs mediated the relation between parental influence tactics and youth physical activity. More specifically, the direct and indirect effects of parents' positive, negative and sedentary-control tactics, the direct effect of parents' desire to change their child's physical activity, and the moderating role of the socio-emotional climate on the relation between parental influence tactics and child outcomes were investigated. Data were collected from 171 4th, 5th, 7th, 8th and 9th grade students and their parents. Pedometers were used to collect youth physical activity data and all participants completed questionnaires. Youth expectancy-value beliefs and negative affective reactions to parental influence tactics were both positively related to youth physical activity. Path analyses revealed that youth expectancy-value beliefs and negative affective reactions fully mediated the direct effects of positive and negative parental influence tactics on youth physical activity, respectively. Moreover, parents' desire to change their child's physical activity was negatively related to parent's use of positive influence tactics. Although several moderators were examined, none were statistically significant (lowest p >.05). The results suggest that additional explanatory power is gained by including a broader range of parental influence tactics and youth affective reactions in models of achievement motivation. The findings are in accord with prior recommendations made to parents with sedentary children.

Time spent alone is a topic that has been studied in great detail, particularly the manner in which it is spent and the effect it has during the adolescent stage of life. Similarly, stress levels in adolescents have always been a topic of interest because of the effects they could have on the individual later in adulthood. Oddly enough however, the two areas of study have never been looked at in relation to one another. This study will look at different types of alone time as possible stressors in a community sample (N=82) of adolescents transitioning to college. The data on time alone and stress levels was collected through diary reports over a period of 3 days. The analysis only yielded significant effects for females and only for specific categories. It was found that females experience the lowest amount of perceived stress when they are alone and want to be alone, they have more negative affect when their desired environment differs from their current situation, and more positive affect in both the alone incongruence and not alone congruence situations. These results indicate that only women experience stress and affect changes when they encounter different congruent and incongruent environments.

The aim of this thesis was to explore whether major life changes can have a visual, perceptible impact on facial changes. The proposed mediation model suggested that changes in personality serve as a mediating factor between life experiences and facial changes throughout the lifetime. The proposed model was tested by examining (1) perceived personality changes, (2) perceived physical changes, and (3) major life changes in photos of individuals' old-aged faces compared to their respective younger faces. Participants in the current study viewed old and young photos of 29 Miss America pageant winners and rated how much each older face changed from its respective younger face on the following criteria: age change, overall change, personality change, and physical change. Responses were aggregated across participants for each target, and personality and physical items were separately composited into single measures of overall perceived personality change and overall perceived physical change. Results did not support the proposed model; however, some marginally significant correlations were found between the number of times the targets experienced a change in marital status and the appearance of being calm, feminine, and less changed in older age. However, these correlations were in the reverse direction from what was expected; further research is needed to understand how marital changes influence, and are influenced by, personality and physical changes. As a form of face perception, the processes underlying the proposed model are discussed in terms of possible social consequences. Further research is needed to explore whether changes in life events, such as the ones presented here, are related to specific facets of personality and physical changes, and how these perceptions translate to important social outcomes. Suggestions for future research pertaining to these issues are discussed.

Religion and the belief in supernatural agents have been assumed to play an important role in encouraging prosocial behavior. However, different studies conducted have shown a complex relation between religion and prosociality. For example, Darley & Batson (1973) found that religious people do not always help strangers. In the present study, Christian participants were primed with benevolent commandments attributed to either the Bible or past historical figures or secular, non-benevolent quotes (control). I then measured their willingness to help pick up envelopes dropped by either a Muslim (wearing a hijab) or non-Muslim confederate woman. The results show that subjects primed with Bible or presidential quotes about benevolence were more likely to be helpful to the Muslim confederate than those in the control group. Differences between the Bible and presidential condition were not significant. I conclude that an authority, whether it be a president or God, promoting benevolence can increase prosocial behaviors toward out-group members.
