The primary objective of this investigation is the formulation of random intercept latent profile transition analysis (RI-LPTA). Our simulation investigation suggests that the election between LPTA and RI-LPTA for examination has negligible impact on the estimation of transition probability parameters when the population parameters are generated…

It is challenging to document the behavior changes that result from Extension programming. This article describes an evaluation method we call the "action items method." Unlike other approaches for measuring behavior change, this method requires program participants to define their own action plans as part of a program and then asks them…

This formative evaluation study of a professional development institute for K-12 educators examined immediate outcomes and short-term impacts on participants' learning and change in mathematics teaching practice. Participants' journals and interviews were analyzed using qualitative methods and a grounded theory (the discovery of theory from…

The authors reviewed the acculturation literature with the goal of identifying measures used to assess acculturation in Hispanic populations in the context of studies of health knowledge, attitudes, and behavior change. Twenty-six acculturation measures were identified and summarized. As the Hispanic population continues to grow in the United…

An international movement has focused on identifying evidence-based interventions that were developed to change psychological constructs and that are supported by controlled studies. However, inconsistent findings within individual intervention studies and among multiple studies raise critical problems in interpreting the evidence, and deciding…

In this article multiple baseline techniques are offered as applied research strategies for counselors who wish to evaluate the effects of the techniques they are using. (Author)

About 40 years since the first controlled study, screening and brief intervention (SBI) are being disseminated into practice. But many unanswered questions remain. Studies in this special issue address what we know and don't know about alcohol and drug SBI, cost-effectiveness, patient preferences, education for clinicians, quality performance…

This commentary outlines considerations in assessing (and programing for) social validity to attain results that are valued by client audiences. It discusses the objectives and contexts of several types of social validation, procedures for conducting a social validation, and questions addressed by researchers in assessing social validity.

The various approaches to research on teaching extend into notions about teacher change. It is difficult to discern whether researchers select research approaches on the basis of their beliefs about teacher change, or vice-versa. Models of teacher change related to these various approaches to the study of teaching include: 1) changing teacher…

The concept of treatment integrity cuts across a diversity of fields involved with providing treatments or interventions to individuals. In medical treatments, the concept of "treatment compliance" or "treatment adherence" is an important and problematic issue. In the field of nutrition, the concept of "dietary adherence" is important for…

Combining psycholinguistic technologies and systems analysis created advances in motivational profiling and numerous new behavioral engineering applications. These advances leapfrog many mainstream statistical research methods, producing superior research results via cause-effect language mechanisms. Entire industries explore motives ranging from…

Selecting a statistical framework for a behavioral study has profoundly different results than does a linguistically framed research strategy. The linguistic strategy overcomes many limitations inherent in statistical strategies and offers more meaningful results. Inferential statistical studies often discuss how the findings "explain" the results…

Introduces strategy for evaluating how drugs, administered in varying doses, affect dependent variables (physiological, psychological, and social functioning and quality of life) that fluctuate in level. Tests hypotheses with statistics computed from benefit/harm scores, measuring longitudinal associations between dose and dependent variable…

Written and spoken language contains inherent mechanisms driving motivation. Accessing and modifying psycholinguistic mechanisms, links language frames to changes in behavior within the context of motivational profiling. For example, holding an object like an imported apple feels safe until one is informed it was grown in a toxic waste dump.…

This commentary affirms that the methodology proposed in a paper by Richard A. Winett and others (EC 601 539) may be useful in conducting social validity assessments and applying these assessment data to improve behavioral interventions. The study of accurate and valid assessment of consumer satisfaction is encouraged. (JDD)
