Reliability and validity of self-report data provided by 178 mentally ill homeless persons were generally favorable. Self-reports of service use also generally agreed with treatment staff estimates, providing further validity evidence. Researchers and administrators can be relatively confident in using such data.

Content analysis of 364 articles in the Journal of Agricultural Education 1990-1999 indicated that a majority of studies did not mention nonresponse error as a threat to external validity, did not attempt to control for nonresponse error, or did not cite literature on handling it. Protocols to address nonresponse error were proposed. (Contains 24…

"How New York City's Charter Schools Affect Achievement" estimates the effects on student achievement of attending a New York City charter school rather than a traditional public school and investigates the characteristics of charter schools associated with the most positive effects on achievement. Because the report relies on an…

Research on facilitated communication (FC) is discussed, along with flaws in previous validation studies and suggestions for improving validation studies, including: testing first whether the person can do the task required under quiet, relaxed conditions; allowing the person to practice the skill until it can be used during the validation test;…

Some of the frustrations inherent in trying to incorporate qualifications of statistical results into meta-analysis are reviewed, and some solutions are proposed to prevent the loss of information in meta-analytic reports. The validity of a meta-analysis depends on several factors, including the: thoroughness of the literature search; selection of…

The purpose of this study was to investigate the methodology of empirical counseling supervision articles published from 1981 to 1987. Seventy-five studies met the criteria for inclusion. Fifty-five articles included adequate information about at least one inferential statistical test to permit computing eta(sup 2), epsilon(sup 2), power, and…

A comparison of the data from the 1976 "Editor and Publisher" poll regarding newspapers' editorial endorsements with data from a survey of the nation's voters suggests that the poll overstates the partisanship of the press and its Republican bias. (GT)

This review of the procedures involved in using path analysis provides guidelines for more effective future utilization of recursive path analysis in the field of family studies. (Author)

Examining the validity of a theory scientifically requires careful attention to how one interprets data. Unfortunately the process is not clear-cut; the theoretical meaning of empirical data is not obvious. The experimental study by Avery et al. (1976) of empathic understanding (EU) is analyzed along with Horwitz's (1977) rejoinder. (Author)

Raises concerns about using interview data in phenomenological research, arguing such data are more related to discourse and the interviewee's perception of what is appropriate to say in the context than to "ways of experiencing," which is the object of study in phenomenography. Also argues that in important respects, discursive…

The National Reading Panel admits its evaluation report on phonics is seriously flawed as to organization, methodology, appropriateness of research base, generalizability of results, reliability, validity, and accuracy of data reported. However, an influential public-relations machine is promoting the study's favorable results as unvarnished…

It is not unusual for interest groups to issue reports that further their own political agendas--and to muddle the facts in the process. For this reason, newspapers generally ignore them, treat them with great skepticism, or make sure they properly vet the research with independent observers. Not so in the case of the study of charter schools…

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…

It has been increasingly realized that (1) multivariate methods are essential in most quantitative studies (Fish, 1988; Thompson, 1992), and (2) all conventional parametric analytic methods are correlational and invoke least squares weights (e.g., the beta weights in regression) (Knapp, 1978; Thompson, 1991). The present paper reviews one very…
