ItemJournal of Multivariate Experimental Personality and Clinical Psychology, v.9 no.3 (complete version)(Wichita State University, Department of Psychology, 1990) ItemThe rejection of the hypothesis of complete independence prior to conducting a factor analysis(Wichita State University, Department of Psychology, 1990) Reddon, John R.Two tests of complete independence were compared in terms of relative power efficiency on 50 equi-correlation matrices and 26 published data sets. Λ1 a test based on Fisher's tanh-1 (r) transformation had greater power efficiency than, Λ0 a test based on -log|R| with finite sample corrections. Consequently, sample size requirements for rejecting P=I should be determined from Λ1 instead of Λ0. In addition, Baggaley's estimate of Q=-log|R|/k from the average absolute off-diagonal correlation was compared with a root mean square estimate of Q. The root mean square estimate was preferable but also demonstrated considerable bias. Because of the bias in estimating Q from the off-diagonal correlations, because Λ1 has greater relative power efficiency for P=I than ?0, and because the test statistic for Λ1 can be approximated from the root mean square off-diagonal correlation, it is preferable to tabulate power results for Λ1 as a function of the average correlation instead of Λo. ItemA brief note on second-order community satisfaction factors for two sub-communities in Istanbul, Turkey(Wichita State University, Department of Psychology, 1990) Bardo, John W.; Dökmeci, Vedia F.First-order Community Satisfaction factors obtained for a sample of residents of Istanbul, Turkey, were subjected to second-order factor analysis; a solution with two oblique factors ("General Satisfaction" and "Excitement/Dullness") resulted. Findings were compared to those of previous studies and results were discussed with regard to their implications for theories of community satisfaction. ItemGlobal and component measures of Type A behavior as predictors of self-reports of psychological symptoms and life enjoyment(Wichita State University, Department of Psychology, 1990) Dielman, T. E.; Moss, G. E.; Harlan, W. R.; Campanelli, P. C.; Butchart, A. T.The structure interview assessment of global Type A behavior and six components of Type A behavior were related to eight indices of psychological symptoms and life enjoyment. The Type A component of verbal response latency (faster responding) was found to be positively correlated with the "Life Enjoyment" index and negatively correlated with the "Life Dissatisfaction," "Psychosomatic Symptoms," and "Depressed Affect" indices. The Type A component of hostility was found to be positively correlated with the indices of "Irritability" and "Anxiety." The hostility and response latency components were the primary, independent predictors of the psychological symptoms and life enjoyment indices in a series of multiple regression analyses in which the global Type A assessment and Type A components were entered as predictors and the effects of demographic variables were held constant. The composition of a global score from component scores which relate to external variables in opposite directions yields attenuated correlations of those external variables with the global score. Failure to attend to interactions of the global or component scores with other classes of variables, such as demographics, can also mask relationships with external variables. ItemA research-oriented private psychological clinic: The potentiality and the actuality(Wichita State University, Department of Psychology, 1990) Dreger, Ralph MasonThe potentiality for research in a private practice psychological clinic is often unrecognized. Clinical psychologists may present good reasons for not doing research for which they are uniquely trained among mental health professionals. Yet it is possible to do research through the private clinic if research procedures are built into its structure and functioning. It has been the observation of others as well as that of the writer that by and large clients are willing to participate in research if they can be assured that no harm will come to them or theirs. Additionally, research procedures can be planned in such a fashion as to maximize both service and research potential. One generalization which arises out of limited but representative experience is that adequate research is directly proportional to the adequacy of the clinic's files. That the potentiality for research can be actualized has been demonstrated by the author's private practice clinic in which different types of research have been carried out.
