This article addresses ethical dilemmas experienced by street-level research and evaluation workers recruiting and gathering data in community-based research projects. The authors focus on a subgroup of street-level research workers, whom they call research extenders (REs), employed because they share important characteristics with the target…

The mood-dependent retrieval hypothesis states that mood will enhance recall by acting as a recall cue if the stimuli have been learned initially in the same mood. Material learned in a happy mood will be best recalled when the person returns to a happy mood; the same holds for a sad mood. Mood-dependent retrieval effect has been regulary…

This paper addresses a variation of the traditional validity question asked of qualitative researchers. Here the question is not "How do we know the qualitative researcher's question is valid?" but rather, "How does the qualitative researcher choose from among a multitude of apparently valid or at least plausible…

This paper summarizes and analyzes data from studies of differential validity and differential prediction for blacks versus whites and females versus males. Forty studies on racial differences and 53 on gender differences were selected from searches of the ERIC, PsychInfo, and Dissertation Abstracts International databases; Buros' Mental…

Adopting the position, expressed by A. P. Bochner in his critique of small group communication research, that placing measurement in a secondary role increases the danger of accepting the claims of experiments with excessive error, this paper examines nine current quantitative small-group communication studies. Using a schema developed by J. F.…

Challenges the typical treatment of causal effects in longitudinal data, arguing that models should be conceptualized and tested in ways that directly reflect prior assumptions as to the trait- or state-like nature of the variables. Examples demonstrate that meaningful longitudinal studies of state variables can be conducted without assuming their…

The methodology of many studies that have identified specific genetic loci for disorders associated with mental retardation is criticized as failing to demonstrate an association between the behavior phenotype and the genetic marker. A more appropriate methodology using a multitrait-multimethod approach is suggested. (Author/JDD)

Three self-report methods for rating secondary sexual characteristic growth were compared to physician ratings; the accuracy of self-reported height and weight was also assessed. The usefulness of the Pubertal Development Scale, Tanner ratings, and self-reported height and weight as adequate estimates of pubertal development is discussed. (PCB)

Criticizes an earlier essay that questioned the validity of contemporary educational research practices, especially those involving experimentation. Argues that research using experimentation is valid and can lead to new and generalizable knowledge. (FMW)

Qualitative research evokes rather stereotyped responses from the mainstream of social science. The following 10 standardized responses to the stimulus "qualitative research interview" (QRI) are discussed: (1) it is not scientific, only common sense; (2) it is not objective, but subjective; (3) it is not trustworthy, but biased; (4) it is not…

The high incidence of reported posttraumatic stress disorder (PTSD) among Vietnam veterans has prompted researchers to search for reliable assessment and treatment procedures for this disorder. Although some encouraging preliminary data on the use of the Minnesota Multiphasic Personality Inventory (MMPI) have been obtained, it is uncertain if this…

This study develops a three-stage model of the question-answering process and investigates several potential sources of extraneous variability. Discussion includes implications of findings concerning what it means to "use" library materials and services, adverbs used as response category labels, and subject's responses as predictors of…

This commentary on EC 602 595 questions cognitive referencing's validity as a model for allocating special services to young children with disabilities. The paper raises methodological issues in studies supporting use of the cognitive referencing model. These issues include the construct of delayed development, subject description, and use of a…

This commentary responds to a critique (EC 601 711) of a paper (EC 211 387) concerning use of cluster analysis to develop a taxonomy of lifestyles of families with severely mentally retarded children. The commentary considers the model to be useful in social science inquiry, and properly validated when using cluster analytic techniques. (JDD)

Describes a case study methodology that combines a three-year longitudinal study with nine retrospective studies about the same phenomenon. Explains how specific strengths in each method compensate for some particular weakness in the other. Suggests circumstances for which dual methodology is especially appropriate. (35 references) (MLF)
