CHARACTERISTICS OF INTERVENTION RESEARCH IN SCHOOL PSYCHOLOGY JOURNALS: 2010-2014

Utility of a slopes difference test for probing longitudinal multilevel aptitude treatment interactions: a simulation

To determine which interventions work best for which students, precision education researchers can examine aptitude-treatment interactions (ATI) or skill-by-treatment interactions (STI) using longitudinal multilevel modeling. Probing techniques like the slopes difference test fit an ATI or STI framework, but power for using slopes difference tests in longitudinal multilevel modeling is unknown. The current study used simulation to determine which design factors influence the power of slopes difference tests. Design factors included effect size, number of waves, number of clusters, participants per cluster, proportion of assignment to the treatment group, and intraclass correlation. Of these factors, effect size, number of waves, number of clusters, and participants per cluster were the strongest determinants of power, model convergence, and rates of singularity. Slopes difference tests had greater power in longitudinal multilevel modeling than where it is originally utilized: multiple regression.

Determining journal article citation classics in school psychology: An updated bibliometric analysis using Google Scholar, Scopus, and Web of Science

Bibliometric analyses have been the primary form of examining and evaluating literature within a field of study. By focusing on citation count and source, researchers have been able to identify journal articles considered to be high impact in reach and relevance, branding them "citation classics" in a field. As time progresses, technology, methods, and metrics for conducting these analyses have improved, and although there have been several studies designed to identify citation classics and patterns of citations supporting them in school psychology literature, none have done so in an updated, comprehensive manner. To address these limitations, the current study aims to replicate and extend these works in three major ways: (a) including 11 primary school psychology journals in the search, (b) using three of the largest reference databases, and (c) collapsing results across these databases to accurately identify the most highly cited articles. The search yielded evidence of more than 12,000 articles accruing more than 500,000 citations. The 100 most highly cited articles were identified, and the majority were classified as explicative (n = 63) and quantitative (n = 70). Themes of bullying, burnout, and teacher-child relationships were the prominent focus. School psychology's citation classics tended to feature quantitative research and examine the relations between constructs, and several revealed a new category of citations classics: the methodological and statistical article.

Measurement of the Effects of School Psychological Services: A Scoping Review

School psychologists are asked to systematically evaluate the effects of their work to ensure quality standards. Given the different types of methods applied to different users of school psychology measuring the effects of school psychological services is a complex task. Thus, the focus of our scoping review was to systematically investigate the state of past research on the measurement of the effects of school psychological services published between 1998 and 2018 in eight major school psychological journals. Of the 5,048 peer-reviewed articles published within this period, 623 were coded by two independent raters as explicitly refering to school psychology or counseling in the school context in their titles or abstracts. However, only 22 included definitions of effects of school psychological services or described outcomes used to evaluate school psychological services based on full text screening. These findings revealed that measurement of the effects of school psychological services has not been a focus of research despite its' relevance in guidelines of school psychological practice.

Evaluating contextually adapted reading interventions with third-grade, Costa Rican students experiencing significant reading difficulties

Scholarship in school psychology has continued to document the need and importance of contextually relevant intervention and prevention research, but this type of research remains relatively scarce. Also problematic, this type of research is even more limited in low- and middle-income countries (LMIC) compared to high-income countries. This situation within school psychology scholarship not only has negative implications for research and practice, it also limits internationalization within the discipline. The geographical context for the present study was in Costa Rica, currently a Latin American LMIC. Given the global importance of literacy, this article describes an experimental evaluation comparing two time- and resource-efficient reading interventions that differed only by instructional grouping: A one-on-one intervention, and an even more resource-efficient small-group intervention. Participants included third-graders experiencing significant reading difficulties. Analyses showed that all students benefitted from intervention, but some students responded somewhat more favorably to one intervention versus the other. Limitations, implications, and future research directions are discussed, particularly within the context of international school psychology and how professionals in the discipline can benefit from more intervention research in otherwise underrepresented global regions.

Geographically representative scholarship and internationalization in school and educational psychology: A bibliometric analysis of eight journals from 2002-2016

Although the discipline of school and educational psychology is arguably international (e.g., relevant research and practice is evident in more than 80 countries), there has been limited research examining the international scholarship published in school and educational psychology journals. Such an assessment is important because it provides one important metric for better understanding the field's level of internationalization. The purpose of this study was to evaluate every article (N = 4456) published from 2002 to 2016 across eight school and educational psychology journals that publish international scholarship. Each article's authorship and participant data were coded and reported in terms of respective country and geographical region. Research questions examined, for example, how the published scholarship aligns with international employment data for school psychologists and whether particular journals published a geographically wider breadth of articles. Overall findings indicated that although the field of school psychology is present in more than 80 countries, the overall scholarship in the reviewed journals predominantly features participants living in, and authors working in, North America or Western Europe. However, one journal (School Psychology International) published relatively more articles with participants from outside of these geographic regions. Also, journals affiliated with a national professional organization largely differed in their percentage of "within-nation" publications (e.g., articles with participants living in the same nation that sponsors the respective journal). Explanations of the data are discussed and several recommendations are made that, if followed, could improve the internationalization and geographical representation of scholarship in school and educational psychology.
