The case history explains the techniques used to introduce research methodology into a service agency for the visually handicapped. (BD)

Reviews a study that examined the validity of different rating scales for measuring instrumental achievement with the clarinet. Rejects the contention that the new rating scales are superior to the Clarinet Performance Rating Scale. (BSR)

The use of nominal group technique in course evaluation has these advantages: it restricts the researcher's influence, encourages respondents to frame their own responses, sustains individual autonomy during group pressure, and provides respondents with knowledge of the full range of possible responses. However, it also underestimates group…

Introspective interviewing can often determine the magnitude of relations more meaningfully than statistical analysis. Deduction from empirically validated premises avoids many research design problems. Guesswork can be combined with sensitivity analysis to determine the effects of guesses and missing information on conclusions. (Author/DWH)

Questioned the statistical analyses of the Moleski and Tosi investigation of rational-emotive therapy versus systematic desensitization. Suggested means for lowering the error rate through a more efficient experimental design. Recommended a reanalysis of the original data. (LLL)

Stakeholder-based studies modify the relationship between evaluator and user, producing conflict that can cause evaluators to regress to familiar, traditional patterns that leave interactive evaluation strategies only partially implemented. (Author/PN)

A novel solution to the statistical problems in an evaluation of rare events is described. The significance of variations in the number of child homicides is analyzed in a binary time series of "active" months for monitoring future incidence and related systemic events. (Author/CM)

The design and conduct of a national evaluation study is discussed, demonstrating that a control group may not provide the no-cause baseline information expected. Resolution of this problem requires reexamination of paradigms, research practices, and policies, as well as the underlying real world constraints and views that generate them. (PN)

Shows how evaluation design and federal involvement in Youth Employment Demonstration Projects unintentionally cause a negative appraisal. Indicates the problem stems from interaction of the contract research corporation, the educational research establishment, and the federal bureaucracy, rather than a specific methodology or bureaucratic…

Criteria for usefulness of evaluative information have changed and this means the model of evaluation used by extension must meet the new criteria. Evaluation research is now considered the legitimate model for evaluation; it can aid decision makers by providing data for making unpopular decisions. (LRA)

Is it ethical to select clients at random for a beneficial social service, then deny the benefits to a control group for the sake of science? Participation of control groups in planning, implementation and evaluation of social programs may resolve ethical issues. (Author/CP)

To guide the unbiased process of visual inference, a four-step model is presented for the assessment of reliability, intervention effect, meaningfulness, and generalizability. A Visual Inference Checklist (VIC) systematizes this assessment process. (Author)

Discusses problem preparation and specification along with search strategies and techniques employed by an information scientist in assisting users of on-line data bases, and briefly reviews ways to save computer time. (CWM)

Employed triangulation strategy for assessing family interaction, involving family members, therapist, and coders independently viewing videotapes. Found weak agreement between paired assessments within family triad, and within therapist-coder dyad. Findings suggest that methodological and/or scaling strategies designed to maximize agreement may…

In this pilot study, 14 adolescents kept diaries for 6 consecutive weeks during their pregnancies. Diary entries were analyzed for affective tone, emotional lability, and contextuality. Findings question psychometric properties of data gathered using one time, self-report measures with pregnant adolescents because of their fluctuating mood states.…
