    Data for: A Review of Literature Published in EMIP from 2005-2019
    (2020-03-18) Rios, Joseph A; Rohloff, Corissa T; Ihlenfeldt, Samuel D; Riegelman, Amy; Zieffler, Andrew; jrios@umn.edu; Rios, Joseph A; Improving Educational Measurement Practice Lab
    Within any scientific field, there is an occasional need to summarize existing research—to not only reflect on current thinking, but to also indicate where the field may be headed. This holds particularly true in the field of educational measurement, where, to date, there has not been a review of general measurement practices in the published literature. To fill this gap, this study conducted a review investigating the author, keyword, methodological, and citation characteristics of empirical studies published in Educational Measurement: Issues and Practice from 2005-2019. Included are the data for the study, keyword, and citation analysis, as well as the code used to conduct these analyses.

    Effectiveness and Key Components of School-Based Anxiety Interventions
    (2019-05) Erhardt, Victoria
    Anxiety disorders and subclinical anxiety symptoms are prevalent in childhood and adolescence, highlighting the need for prevention and early intervention efforts. While research has demonstrated positive effects for some school-based anxiety interventions, additional research is warranted to ascertain program effectiveness, composition, and delivery to best meet student needs. This multi-study dissertation project comprised of two studies. Study 1 was a systematic literature review that examined anxiety interventions for youth in school settings and updated and expanded a previous systematic review (Neil & Christenson, 2009) to more fully understand the state of the science regarding school-based anxiety programs. Randomized controlled trials (RCT) from articles published between 2008 and June 2016 were reviewed and evaluated in areas including program effectiveness, program content, intervention intensity, and participant age. Twenty-two RCTs, representing 9,693 study participants, were coded and analyzed. Results indicated that 43% of trials reported statistically significant reductions in anxiety (ES = -0.69 to -0.15) with the majority of programs based in cognitive behavioral therapy (CBT). Results from Study 1 were used to inform the development and implementation of an applied school-based anxiety intervention. In Study 2, Think Good Feel Good was implemented as a low-cost, 6-week, CBT-based modularized intervention to address student anxiety in an elementary school utilizing a multiple-baseline single case design. The main purpose was to analyze the effectiveness of the program as measured by formative and summative anxiety assessment measures following a multi-method, multi-source approach. Participants included 14 students across third, fourth, and fifth grades at a public elementary school. Results of the study indicated both responders and non-responders to the intervention. Self-report data on the Multidimensional Anxiety Scale for Children (MASC-2) pre/post assessments showed statistically significant anxiety reduction on the generalized anxiety disorder and the physical symptoms scales, whereas parent and teacher pre/post data and progress monitoring data revealed mixed findings. Social validity data from students indicated high acceptability and perceived utility. The implications of the results from this dissertation project for future research and practice are discussed.

    Efficacy of antibiotic and non-antibiotic interventions in preventing and treating necrotic enteritis in broiler chickens: a protocol for a systematic review
    (2020) Bueno, Irene; Smith, Emily; Hwang, Haejin; Nault, Andre J.; Valeris-Chacin, Robert; Singer, Randall S.
    Necrotic enteritis is one of the most common and economically important bacterial diseases affecting the broiler industry. Limitations on the use of antimicrobials have highlighted the need to evaluate the efficacy of non-antibiotic alternatives and management strategies. However, the available evidence on the efficacy of non-antibiotic interventions for necrotic enteritis has not been systematically synthesized. Here we present a protocol to conduct a systematic review of the literature to assess the efficacy of non-antibiotic interventions compared to antibiotic interventions in preventing and treating necrotic enteritis cases in broiler chickens.

    Frequency of Nonodontogenic Pain after Endodontic Therapy: A Systematic Review and Meta-Analysis
    (Elsevier, 2010-09) Nixdorf, DR; Moana-Filho, EJ; Law, AS; McGuire, LA; Hodges, JS; John, MT
    INTRODUCTION: Little is known about ill-defined pain that persists after endodontic procedures, including an estimate of the problem's magnitude. We conducted a systematic review of prospective studies that reported the frequency of nonodontogenic pain in patients who had undergone endodontic procedures. METHODS: Nonodontogenic pain was defined as dentoalveolar pain present for 6 months or more after endodontic treatment without evidence of dental pathology. Endodontic procedures reviewed were nonsurgical root canal treatment, retreatment, and surgical root canal treatment. Studies were searched in four databases electronically, complemented by hand searching. A summary estimate of nonodontogenic tooth pain frequency was derived using random-effects meta-analysis. RESULTS: Of 770 articles retrieved and reviewed, 10 met inclusion criteria, and nine had data on both odontogenic and nonodontogenic causes of pain. A total of 3,343 teeth were enrolled within the included studies and 1,125 had follow-up information regarding pain status. We identified 48 teeth with nonodontogenic pain and estimated a 3.4% (95% confidence interval, 1.4%-5.5%) frequency of occurrence. In nine articles containing data regarding both odontogenic and nonodontogenic causes of tooth pain, 56% (44/78) of all cases were thought to have a nonodontogenic cause. CONCLUSIONS: Nonodontogenic pain is not an uncommon outcome after root canal therapy and may represent half of all cases of persistent tooth pain. These findings have implications for the diagnosis and treatment of painful teeth that were previously root canal treated because therapy directed at the tooth in question would not be expected to resolve nonodontogenic pain.

    Frequency of persistent tooth pain after root canal therapy: a systematic review and meta-analysis
    (Elsevier, 2010-02) Nixdorf, DR; Moana-Filho, EJ; Law, AS; McGuire, LA; Hodges, JS; John, MT
    Little is known about the frequency of persistent pain after endodontic procedures even though pain is a core patient-oriented outcome. We estimated the frequency of persistent pain, regardless of etiology, after endodontic treatment. METHODS: Persistent tooth pain was defined as pain present > or = 6 months after endodontic treatment. Endodontic procedures included in the review were pulpectomy, nonsurgical root canal treatment, surgical root canal treatment, and retreatment. Four databases were searched electronically complemented by hand searching. Two independent reviewers determined eligibility, abstracted data, and assessed study quality. A summary estimate of persistent all-cause tooth pain frequency was established by using a random-effects meta-analysis. Using subgroup analyses, we explored the influence of treatment approach (surgical/nonsurgical), longitudinal study design (prospective/retrospective), follow-up rate, follow-up duration, initial treatment versus retreatment, and quality of reporting (Strengthening the Reporting of Observational Studies in Epidemiology rankings) on the pain frequency estimate. RESULTS: Of 770 articles retrieved and reviewed, 26 met inclusion criteria. A total of 5,777 teeth were enrolled, and 2,996 had follow-up information regarding pain status. We identified 168 teeth with pain and derived a frequency of 5.3% (95% confidence interval, 3.5%-7.2%, p < 0.001) for persistent all-cause tooth pain. High and statistically significant heterogeneity among studies (I2 = 80%) was present. In subgroup analysis, prospective studies had a higher pain frequency (7.6%) than retrospectives studies did (0.9%). Quality of study reporting was identified as the most influential reason for study heterogeneity. CONCLUSIONS: The frequency of all-cause persistent tooth pain after endodontic procedures was estimated to be 5.3%, with higher report quality studies suggesting >7%.

    The Influence of Private Equity on Eating Disorder Treatment Centers
    (2024-03) Thompson, Leslie
    This systematic literature review analyzes the influence of private equity (PE) firms in the landscape of residential eating disorder treatment. Given the absence of peer-reviewed research on this topic, this review broadens its scope to include an examination of research on residential treatment facilities serving other vulnerable populations, including nursing homes and substance abuse facilities, and the grey literature specifically focused on residential eating disorder treatment. The synthesis of findings aims to provide a comprehensive understanding of the impact of PE firm influence on critical aspects of eating disorder treatment. Following the synthesis, research and policy recommendations are proposed to address the identified issues in the findings. Key themes explored in this review encompass the systematic preference for patients with specific insurance benefits and lower clinical complexity, discernible shifts in service provision after PE acquisitions, and differences in the quality of care in PE firm-owned healthcare facilities, such as staff-to-patient ratios. This review contributes to advancing the understanding of how the presence of PE shapes the landscape of residential eating disorder treatment by offering valuable insights for policymakers, practitioners, and researchers.

    (2020) Valeris-Chacin, Robert; Nault, Andre J.; Hwang, Haejin; Weber, Bonnie; Bueno, Irene; Johnson, Timothy J.; Pieters, Maria; Singer, Randall S.
    Use of prebiotics and probiotics as an alternative to antibiotics is increasing in poultry 16 production. However, there is still uncertainty about their efficacy in controlling the spread of 17 human pathogens in poultry. This paper describes the protocol for a systematic review assessing18 the efficacy of prebiotics and probiotics in reducing the colonization and shedding of 19 Campylobacter and Salmonella in broiler chickens and turkeys. The objective of this protocol is 20 to document the methodology that will be used for the systematic review a priori.
