Conducted studies using two perspectives for obtaining evidence relevant to validity of autobiographical data. In Study 1, construct validity of standard psychological constructs (assertiveness, trustworthiness) obtained from autobiographies was equal to that of standard instruments designed to assess these constructs. Evidence for validity of…

Identifies six categories of design and methodological errors contained in the 39 empirical studies of neurolinguistic programming (NLP) documented through April 1984. Representative reports reflecting each category are discussed. Suggestions are offered for improving the quality of research on NLP. (Author/MCF)

Describes methodological problems associated with present research examining the use of interpretation in time-limited individual therapy. Offers recommendations on making research on interpretation more methodologically rigorous and relevant. (Author/CM)

Conducted three studies to examine what segment of counseling interview best represents entire interview and whether different starting points yield different results. Results suggest that, whereas starting points make little difference, generalizing from any size segment to whole session should not be done when examining interviews individually.…

It is recommended that levels of analysis of variance (ANOVA) designs be applied to carrier variables to help overcome the lack of unambiguously generablizable results in many applied experiments. (Author)

Although the primary responsibility rests with the authors of articles reporting nonsignificant results to demonstrate the worth of the results by discussing the power of the tests, consumers should be prepared to conduct their own power analyses. This article demonstrates the use of power analysis for the interpretation of nonsignificant…

Examines the prevalence of inflated Type I error in counseling research and recommends wider use of multivariate statistics to correct the problem. Type I error becomes inflated beyond acceptable levels when researchers perform individual univariate statistics on each of several dependent variables within a single project. (Author)

Proposes that in comparing time-limited and time-unlimited treatments, it is important to operationally define each to stimulate the desired expectancies in each condition. Discusses the article by Kelly and Stone (1982). Delineates some important parameters of time manipulations. (Author)

Evaluated alternate assessment methods by comparing subject assertiveness, two methods of scene presentation, and two methods of response generation in repeated measures design. For self-efficacy, printed scene plus experimenter-prepared response condition yielded significantly higher ratings than all other conditions. For outcome expectancy,…

Demonstrates that magnitude-of-effects (ME) estimates vary in susceptibility to sample-size bias depending on whether they are directional or nondirectional estimates. Also demonstrates that study characteristics that influence size of ME estimates can be explicitly taken into account when comparing studies. Emphasizes need to consider study…

Calls attention to limitations and dangers in routine application of multivariate analysis of variance (MANOVA), describes some alternative procedures, and laments the necessarily pervasive character of the statistical problem. (Author)

In exercising reasonable caution to preserve the integrity of counseling, counselors inhibit the use of research methods most likely to lead to improvements in counseling. The purposes of this paper are (a) to explore one possible solution to this problem, and (b) to describe a laboratory based counseling research program. (Author)

Presents several multivariate analyses of variance (MANOVA) test procedures. Discusses guidelines for choosing an overall MANOVA test statistic and post hoc tests that determine the dependent variable or variables responsible for any significant effects. Concludes that guidelines based on recent comparisons of the various test statistics be used.…

The author illustrates the shortcomings of pooling data from replication and original studies. If combining data is deemed necessary, procedures should be rigorous to identify statistically widen study differences. When sources of variation are easily identifiable, an analysis of variance may be superior to a series of separate t-tests.…

Outlined method for studying rater bias in counseling and psychotherapy. Used method to study three potential sources of rater bias concerning characteristics of rater, client, and therapist. Examined ratings on Collaborative Study Psychotherapy Rating Scale for 826 sessions of psychotherapy in Treatment of Depression Collaborative Research…
