Some sampling characteristics of three estimators of the intraclass correlation were investigated under a variety of conditions within the context of a one-way analysis of variance. The results promote caution in the use of all three estimators. The three estimators differed very little in their bias or in their standard errors. (Author/JKS)

Procedures to estimate the magnitude of a treatment effect are examined for analysis of variance (ANOVA) designs which have repeated-measures. In particular, it is argued that the estimate of utility (strength of effect) for a within-subjects variable should be adjusted to reflect the underlying ANOVA model. (Author/JKS)

A FORTRAN computer program was derived for an IBM series 360/370 computer system that provides a factor analytic solution for large three-dimensional data matrices. The computational procedures employed are based upon those presented in Method III by Tucker. (Author/JKS)

Commentary is presented on the preceding articles in this issue of the journal. Critical commentary is made article by article, and some general recommendations are made. (See TM 503 664 through 670). (JKS)

Issues raised at an interdisciplinary conference on "Dialectics: a paradigm for the social sciences" are reviewed. The conference focused on the role of dialectical theory and methodology in designing and interpreting research in the social sciences. (BD)

Subroutines to calculate exact chi square and Fisher's exact probability tests are presented for 3 by 2 cross-classification tables. A nondirectional probability value for each test is computed recursively. (Author/GDC)

Discusses current themes in communication research. Claims that this research offers an increasingly sophisticated view of journalism as a reflection not of an objective reality, but of political-economic power and sociocultural conflict. Includes an example of an imaginary symposium and a strategy for reframing the journalistic quest for truth.…

Contends that theoretical and conceptual problems relating to the validation of assessment centers must be resolved before quantitative validation methods may be used. An open design is suggested to facilitate conceptual clarification. (CH)

Argues for the application of behavioral methods including natural observations over reification in parapsychological research. Research methodology stressing the importance of observation, replication, and continuity in applied science is discussed. (Author/BL)

Outlines costs and benefits associated with different cross-validation strategies; in particular the way in which the study design affects the cost and benefits of different types of cross-validation. Suggests that the choice between empirical estimation methods and formula estimates involves a trade-off between accuracy and simplicity. (JAC)

Over the last decade emphasis has shifted from theoretically based models of practice to empirically based models whose elements are derived from clinical research. These models are defined and a developing model of practice through the use of single-case methodology is examined. Potential impediments to this new role are identified. (Author/BL)

Describes problems in implementing placebo controls in psychotherapy including the difficulty of ensuring that therapists and their patients will view both the experimental and placebo treatments as comparably credible. Considers six research issues stemming from the definitional requirement that the placebo control for the critical and specific…

Considers multiple design issues and strategies raised by comparative outcome studies including the conceptualization, implementation, and evaluation of alternative treatments; assessment of treatment-specific processes and outcomes; and evaluation of the results. (Author/BL)

Author responds to critique by Daniel Griffiths (Educational Administration Quarterly v. 19, p. 201-21) by defending his work in three areas: derivation of hypotheses, testing of hypotheses, and erroneous attribution of assumptions. (JW)

Suggests a framework for structured observation using a psychosocial approach to describe work styles, differences in performance, and outcomes of behavior patterns. (JW)
