New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a given thesis/dissertation in DRUM.

    An Investigation of Child and Adolescent Dental Sealant Predictors, NHANES 2011-2012
    (2016) Roman, Agnieszka Anna; Kleinman, Dushanka; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Objective: To examine sociodemographic and dental factors for associations with dental sealant placement in children and adolescents aged 6-18 years old. Methods: Secondary data analysis of 2011-2012 NHANES data was conducted. Multiple logistic regression models were used to assess relationships between predictor variables and sealant presence. Results: More than a third (37.1%) of children and adolescents have at least one sealant present; 67.9% of children compared with 40.4% of adolescents. Racial/ethnic differences exist, with Non-Hispanic black youth having the lowest odds of having sealants. Sealant placement odds vary by presence of dental home; the magnitude of the odds varies by age group. Those with untreated decay have lower odds of having sealants than those who do not have untreated decay (child OR: 2.6, 95% CI: 1.83-3.72; adolescent OR: 3.9, 95% CI: 2.59-6.07). Conclusion: Disparities exist in odds of sealant prevalence across racial/ethnic groups, income levels, and dental disease and visit characteristics. Further research is necessary to understand the reasons for these differences and to inform future interventions.

    Factors Influencing Childhood Swimming Instruction: Evaluation of the "Safe Water Initiative: Maryland" Program for Drowning Prevention
    (2010) Monteiro, Erinn Hurley; Green, Kerry M; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Background: Increasing swimming ability is a key preventive step in decreasing childhood drowning, a leading cause of unintentional mortality in the U.S. Yet, it remains unclear what factors influence parents to ensure that their children learn to swim. This study examined how attitudes, beliefs, perceptions, and barriers relate to parents' intentions and decisions to seek swimming instruction for their children. The evaluation also examined whether free introductory swimming lessons may be a useful model in changing any of these factors. Methods: The Safe Water Initiative: Maryland (SWI:M) community-based program provided free introductory lessons in summer 2010 to over 100 children who had previously never received swimming instruction. Parents/guardians completed pretest (N = 81) and posttest (N = 79) written surveys as well as a second follow-up online survey six weeks after the program ended (N = 71). The pre-and post-test surveys included questions about barriers as well as two scales on attitudes/beliefs about swimming importance and perceptions about drowning risk. These two scales were developed and their reliability (alpha=.70-.89) and validity evaluated as part of this study. Results: Participants were predominantly African-American mothers, the majority of whom had little to no swimming ability. Results revealed significant increases in attitudes/beliefs, perceptions, and intentions from the beginning to the end of the SWI:M program. While attitudes/beliefs and perceived susceptibility were significant predictors of intentions, strong intentions did not predict behavior, as only 14% of participants' children had received additional swimming lessons by the second post-test. Cost was reported as a significant barrier to pursuing additional instruction. Conclusions: This study provides preliminary findings for future research investigating factors influencing childhood swimming instruction. Reduced- or no-cost swimming lessons may be a key drowning prevention method, but additional research is warranted to find ways to address prevailing barriers. Evaluating the effectiveness of this and other programs is an important step in potentially decreasing morbidity and mortality due to drowning.

    Survey of Maryland Dentists' Knowledge, Opinions and Practices About Oral Cancer Prevention and Early Detection
    (2010) Maybury, Catherine A.; Green, Kerry; Public and Community Health; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    To reduce the morbidity and mortality associated with oral cancer, dentists must have oral cancer prevention and early detection knowledge and skills, and they must perform routine screening examinations. Maryland dentists were surveyed to assess their knowledge, opinions and screening practices relating to oral cancer prevention and early detection. Thirty-eight percent of dentists had a high level of knowledge of oral cancer risk factors, thirty-nine percent had a high level of knowledge of oral cancer diagnostic procedures, and thirty-eight percent received a high score for provision of oral cancer examinations. Dentists who strongly agreed or agreed that their oral cancer knowledge is current were more likely to receive a high score for knowledge of oral cancer diagnostic procedures and knowledge of risk factors and diagnostic procedures combined. Deficiencies exist in dentists' knowledge and practices relating to oral cancer. Actions are needed in education, policy and research to address these deficiencies.

    Outcomes of an elementary grades social competence experiment according to student self-report
    (2008-06-30) Harak, Elise Touris; Gottfredson, Gary D; Counseling and Personnel Services; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Problem behaviors that emerge in early childhood often persist through adolescence. Evaluations provide evidence that social skills programs in elementary schools can reduce student aggression. There is some evidence that social skills programs also increase social skills, academic commitment, and achievement. Outcome evaluations have more often focused on aggression than on social skills and academics, however. The present study is a randomized, controlled trial evaluating the effects of one popular social skills instructional program, Second Step, in six treatment and six control schools after two years of implementation. Despite the widespread use of Second Step, few evaluations have assessed its effects. The existing evaluations have either: (a) lacked randomization, (b) had small samples, (c) not measured implementation, or (d) were implemented for one year or less. In the present evaluation, implementation data were collected from all teachers as each lesson was completed. Overall implementation was high across two years. Treatment effects were assessed on nine self-report measures including Engagement in Learning, prosocial behaviors (Altruism, Empathy, and Self-Restraint) and problem behaviors and attitudes (Rebellious Behavior, Aggression, Victimization, Acceptability of Aggression, and Hostile Attribution Bias). Analyses completed using hierarchical linear modeling (HLM) implied that treatment did not statistically significantly affect individual student self-reports net of individual characteristics. In almost all cases, the non-significant estimates of treatment effects were in the desired direction but mirrored non-significant pre-intervention differences.
