Description
The effects of preventive interventions are found to be related to participants' responsiveness to the program, or the degree to which participants attend sessions, engage in the material, and use the program skills. The current study proposes a multi-dimensional method for measuring responsiveness to the Family Bereavement Program (FBP), a parenting-focused program to prevent mental health problems for children who experienced the death of a parent. It examines the relations between individual-level risk-factors and responsiveness to the program, as well as the relations between responsiveness and program outcomes. The sample consists of 90 caregivers and 135 children assigned to the intervention condition of an efficacy trial of the FBP. Caregivers' responsiveness to the 12-week program was measured using a number of indicators, including attendance, completion of weekly "homework" assignments, overall program skill use, perceived helpfulness of the program and program skills, and perceived group environment. Three underlying dimensions of responsiveness were identified: Skill Use, Program Liking, and Perceived Group Environment. Positive parenting and child externalizing problems at baseline were found to predict caregiver Skill Use. Skill Use and Perceived Group Environment predicted changes in caregiver grief and reports of child behavior problems at posttest and 11-month follow-up. Caregivers with better Skill Use had better positive parenting outcomes. Skill use mediated the relation between baseline positive parenting and improvements in positive parenting at 11-month follow-up.

Description
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.

Description
Child abuse and neglect is a devastating yet preventable social problem. Currently, early childhood home visitation services are the primary approach to preventing maltreatment and improving child well-being in the United States. However, existing literature suggests that improvement is needed regarding how home visitation professionals identify and respond to risk factors for child abuse and neglect. Although there is substantial multidisciplinary literature that investigates the utility of standardized measures to determine future risk for maltreatment, there has been minimal inquiry into the validity of early childhood home visitation assessment instruments to accurately identify and classify children and their families by their risk for future maltreatment. In response to the dearth in the literature, the purpose of this dissertation was to examine the utility of the Healthy Families Parenting Inventory (HFPI) to predict a family’s risk for future maltreatment. Families enrolled in Healthy Families Arizona, a child abuse and neglect prevention program, were followed for 12 months after the completion of the baseline HFPI to measure if the family had received an investigation of maltreatment from the public child welfare system. Bivariate results indicated that the generated risk classifications of the HFPI and the overall total composite score were related to the occurrence of a future maltreatment investigation. Specifically, the results from the binary logistic regression models provided evidence that as a family’s score increased on the inventory, the likelihood of receiving an investigation of maltreatment decreased. Further, significant relationships were found between a family’s score on several individual items of the HFPI and the occurrence of a maltreatment investigation. This dissertation concludes with a discussion of potential avenues of research on the topic of risk assessment in prevention programs serving at-risk families.

Description
The influenza virus, also known as "the flu", is an infectious disease that has constantly affected the health of humanity. There is currently no known cure for Influenza. The Center for Innovations in Medicine at the Biodesign Institute located on campus at Arizona State University has been developing synbodies as a possible Influenza therapeutic. Specifically, at CIM, we have attempted to design these initial synbodies to target the entire Influenza virus and preliminary data leads us to believe that these synbodies target Nucleoprotein (NP). Given that the synbody targets NP, the penetration of cells via synbody should also occur. Then by Western Blot analysis we evaluated for the diminution of NP level in treated cells versus untreated cells. The focus of my honors thesis is to explore how synthetic antibodies can potentially inhibit replication of the Influenza (H1N1) A/Puerto Rico/8/34 strain so that a therapeutic can be developed. A high affinity synbody for Influenza can be utilized to test for inhibition of Influenza as shown by preliminary data. The 5-5-3819 synthetic antibody's internalization in live cells was visualized with Madin-Darby Kidney Cells under a Confocal Microscope. Then by Western Blot analysis we evaluated for the diminution of NP level in treated cells versus untreated cells. Expression of NP over 8 hours time was analyzed via Western Blot Analysis, which showed NP accumulation was retarded in synbody treated cells. The data obtained from my honors thesis and preliminary data provided suggest that the synthetic antibody penetrates live cells and targets NP. The results of my thesis presents valuable information that can be utilized by other researchers so that future experiments can be performed, eventually leading to the creation of a more effective therapeutic for influenza.

Advancements in both the medical field and public health have substantially minimized the detrimental impact of infectious diseases. Health education and disease prevention remains a vital tool to maintain and propagate this success. In order to determine the relationship between knowledge of disease and reported preventative behavior 180 participants amongst the ASU student population were surveyed about their knowledge and prevention behavior for 10 infectious diseases. Of the 180 participants only 138 were completed surveys and used for analysis. No correlation was found between knowledge or perceived risk and preventative measures within the total sample of 138 respondents, however there was a correlation found within Lyme disease and Giardia exposure to information and prevention. Additionally, a cultural consensus analysis was used to compare the data of 17 US-born and 17 foreign-born participants to analyze patterns of variation and agreement on disease education based on national origins. Cultural consensus analysis showed a strong model of agreement among all participants as well as within the US-born and foreign-born student groups. There was a model of agreement within the questions pertaining to transmission and symptoms. There was not however a model of agreement within treatment questions. The findings suggest that accurate knowledge on infectious diseases may be less impactful on preventative behavior than social expectations.

Description
Despite the evidence that suicide risk assessment training is necessary only 40-50% of psychology programs offer risk assessment training (Granello & Juhnke, 2010). In the present study an online suicide risk assessment and safety plan training workshop for graduate students in the field of psychology was investigated. Participants were randomly assigned to the control condition (lecture) or the treatment condition (lecture + demonstration). Measures of declarative knowledge of suicide risk and protective factors, application to clinical scenarios, and risk assessment and management self-efficacy scales were administered before and after completion of the workshop. Two way repeated measures ANOVA's were conducted with repeated time measures to evaluate the Time X Condition interaction. While there was a significant main effect of time on all three dependent variables, there was no significant time X condition interaction. In contrast to predictions, the added component of a demonstration did not result in greater improvements in application to clinical scenario multiple choice questions or risk assessment and management self-efficacy. Post hoc moderation analysis revealed demonstration enhanced the effects of knowledge acquisition and assessment of clinical scenarios for individuals who reported the training was less relevant to their current work. Implications of findings and directions of further research are discussed.

Description
The present study contributed an investigation of prosocial peers, a prospective promotive factor, and its association with depressive symptoms, an internalizing outcome. The study utilized six waves of panel data from 2,002 youth in the control condition of the Community Youth Development Study (mean age 13.12 at Grade 7; 52% male; 66.1% White; 26.6% Hispanic). A series of time-varying effect models (TVEM) illustrated the associations between prosocial peers and depressive symptoms over developmental time from Grades 7 through 12. It was hypothesized that prosocial peers and depressive symptoms would have a negative association for both males and females, and that the association would be moderated by gender at the time of transition to high school. It was expected that females would display a significantly stronger negative association than males between prosocial peers and depressive symptoms at this juncture, particularly due to gender-based differences in socialization that are compounded by transition. To strengthen conclusions about prosocial peers being a promotive factor, secondary analyses included covariates measuring previous levels of depressive symptoms; these models accounted either for baseline depressive symptoms or year-prior symptoms. Results showed, overall, prosocial peers had a significant negative association with depressive symptoms over time, for both males and females. When controlling for baseline depressive symptoms, this was still the case. When controlling for year-prior depressive symptoms, prosocial peers was no longer significantly associated with depressive symptoms for males across Grades 10 through 12. Gender moderated the association between prosocial peers and depressive symptoms at the time of transition to high school as well as other grades. When controlling for baseline depressive symptoms, it was again found that gender moderated the association between prosocial peers and depressive symptoms at the time of transition to high school (Grades 8 and 9) but also at Grade 12. When controlling for year-prior depressive symptoms, gender did not moderate the association at the time of transition to high school, but it did at Grades 10, 11, and 12. Overall, results support the possibility of prosocial peers as a prospective promotive factor for youth mental health.

Description
Implementation challenges associated with low community effectiveness rates include low levels of client responsiveness to the intervention, less than ideal intervention fidelity, and low levels of provider quality of intervention delivery. The literature is mixed on how group leader fidelity/quality of delivery are associated with client responsiveness, and research on adolescents and ethnoracially diverse clients is particularly lacking. The current study examined group leader fidelity and quality of delivery as predictors of adolescent in-session group responsiveness to the first session of the Bridges intervention which is a universal, family-based, substance use prevention program delivered in Title I middle schools. Participants consisted of 325 adolescents across 30 intervention groups. Three separate observational coding teams coded group leader fidelity, group leader quality of delivery, and adolescent in-session group responsiveness to the program. Overall percentage of fidelity met was calculated. Next, two confirmatory factor analysis models were conducted on the responsiveness and quality of delivery data of session 1, and factor scores were extracted. Hierarchical linear regression was then conducted to predict adolescent responsiveness with group leader fidelity in step 1 and group leader quality of delivery in step 2. There were no significant associations between predictor variables and adolescent in-session group responsiveness. Findings suggest that group leader implementation constructs do not appear to account for a significant amount of the variance in adolescent group responsiveness during the first session. Future research should examine other variables that are relevant in influencing adolescent program engagement with larger sample sizes.

Description
In a world where everything is drifting away from the intellectual into materialistic, and where everyone is rushing on the daily basis to provide their basic needs, everything is getting more expensive except the human life’s worth. Construction sites can be some of the clearer examples that show how the technical work, the communication skills, team work and management relate to one another. However, lately, the safety of the labor is neither being prioritized nor considered an important aspect to even consider at sites. Lebanon is, unfortunately, one of the countries where most construction sites are aimed to increase production and decrease cost as much as possible, on behalf of labor safety measurements. The high occurrence of such cases are the result of the lack of government control and accountability, as well as other reasonings.
Similar to the majority of countries, falls are the number one cause of fatalities and serious injuries on construction sites, especially building sites, where working on higher elevations is a must.
This thesis focuses on the topic of “Techniques and technologies for reducing fall hazards in use on Lebanese building construction projects”. The main goal behind it is to shed light on whether there are any traditional, technical or modern mechanisms used for safety on the Lebanese construction sites, however statistically few they might be. On the other hand, Casting the deficiencies, weaknesses and flaws are also discussed by indicating some solutions and pointers on possible methods to improve. Hence, this thesis would demonstrate the high importance of this topic and consequently help construction managers and workers realize that safety should become a priority on all sites in the country.
Researches done and interviews conducted show that fall hazards prevention/protection techniques are only implemented by large scale companies, and totally ignored by other companies which constitute the highest percentage of the active companies in the market now. Several causes are behind this and the result is one: More lives are put in danger due to lack of education, absence of audits and sanctions, and insufficient budgets

Description
This study examined whether the New Beginnings Program (NBP), a preventive parenting intervention, led to changes in coping strategies and coping efficacy in emerging adults whose families had participated in the program 15 years earlier. Gender and baseline risk were examined as moderators of these relations. Participants (M = 25.6 years; 50% female) were from 240 families that had participated in an experimental trial (NBP [mother-only, mother-child] vs. literature control). Data from the pretest and 15-year follow-up were used. Multiple regression analyses revealed that pretest risk interacted with program participation in the mother-only condition of the NBP such that offspring entering the program with higher pretest risk reported significantly less avoidant coping 15 years later. There was a marginal effect of participation in the NBP on problem-focused coping; emerging adults who had participated in the NBP had marginally higher levels of problem-focused coping. There were no significant main effects nor interactive program by risk or program by gender effects on support coping or coping efficacy. Results are discussed in terms of their implications for implementation of preventive interventions and research on pathways of coping.
