Evaluating school-based mental health services for children and youth with emotional disturbance (ED) has been a challenge for researchers. One particular challenge is the study design of using the student as the statistical unit of analysis, which in certain cases may lead to a violation of the "independence of error" assumption.…

Little is known about effective eHealth recruitment methods. This paper presents recruitment challenges associated with enrolling African-American girls aged 8-10 years in an eHealth obesity prevention program, their effect on the recruitment plan, and potential implications for eHealth research. Although the initial recruitment strategy was…

Many evaluation researchers are now attempting to synthesize quantitative and qualitative approaches. Although such efforts appear to carry great promise, some subtleties and incompatibilities of these approaches are perhaps being overlooked. Implications for social inquiry are discussed.

Strasser and Deniston's own analysis (TM 504 254) shows that post-planned evaluations are unsuitable substitutes for pre-planned evaluations. When viewed as post-experimental interviews, however, post-planned evaluations can produce valuable information which complements traditional experimental and quasi-experimental evaluations. (MH)

Why conclusions of many outcome evaluations do not stand up to scrutiny is discussed, drawing on examples from evaluations of drug abuse prevention programs. Factors that undermine these studies are largely the result of social-structural problems that influence the design and implementation of the research. (SLD)

Seven qualitative issues associated with randomization that have the potential to weaken or destroy otherwise sound experimental designs are reviewed and illustrated via actual field experiments. Issue areas include ethics and legality, liability risks, manipulation of randomized outcomes, hidden bias, design intrusiveness, case flow, and…

Criticizes Strasser and Deniston's post-planned evaluation (TM 504 253) because of their: (1) emphasis on evaluation research; (2) imposition of experimental rigor; (3) inapplicability to human service projects; (4) inattention to congruity between the program and its environment; (5) distinct characteristics of program evaluation; and (6)…
