Background: Multisite designs, also known as blocked designs, are experimental designs in which the random assignment of treatment and control conditions is within each site (or block) after the random selection of sites (or blocks). Multisite designs exhibit remarkable adaptability and, statistically, it can maintain a rigorous basis for…

Factorial surveys use a population of vignettes to elicit respondents' attitudes or beliefs about different hypothetical scenarios. However, the vignette population is frequently too large to be assessed by each respondent. Experimental designs such as randomized block confounded factorial (RBCF) designs, D-optimal designs, or random sampling…

Recent studies show cluster randomized trials may be well powered to detect mediation or indirect effects in multilevel settings. However, literature has rarely provided guidance on designing cluster-randomized trials aim to assess indirect effects. In this study, we developed closed-form expression to estimate the variance of and the statistical…

Classroom context and climate are inherently classroom-level (L2) constructs, but applied researchers sometimes--inappropriately--represent them by student-level (L1) responses in single-level models rather than more appropriate multilevel models. Here we focus on important conceptual issues (distinctions between climate and contextual variables;…

The main goal of the Faculty Perceptions of Intercollegiate Athletics Survey is to examine professors' beliefs about and satisfaction with intercollegiate athletics. The investigation also identifies faculty members' primary concerns about intercollegiate athletics and gathers preliminary data on whether they would join campus-based initiatives…

Theories about, methods of studying, and definitions of family have undergone profound shifts over the last several decades, and change continues to characterize developmental research on family functioning. In the 1990s, researchers have recognized the need for more descriptive studies as well as more process-oriented work. Research is beginning…

After a brief introduction indicating the value of the first Follow Through evaluation, this document offers ideas about how a new wave of Follow Through approaches should be evaluated. The discussion is based on the premise that the form of an evaluation must be derived from the questions for which answers are sought, the audience(s) to whom the…

The recruitment of respondents belonging to ethnic minorities poses important challenges in social and health research. This paper reflects on the enablers and barriers to recruitment that we encountered in our research work with persons belonging to ethnic minorities. Additionally, we applied the Matching Model of Recruitment, a theoretical…
