CPSY 501 Fall 2010 Research Article Review Questions

Before class, please read these two journal articles and try to understand their statistical analyses. Come prepared to discuss the following review questions.

Myers & Hayes, 2006

Myers, D., & Hayes, J. A. (2006). Effects of therapist general self-disclosure and countertransference disclosure on ratings of the therapist and session. Psychothearpy: Theory, Research, Practice, Training, 43(2), 173-185.
  1. How many 'cells' in this study? What are each of the predictors and their levels?
  2. "Pearson's correlation coefficients among the dependent measures ranged from .13 to .69" (p. 179)
    What assumption of parametric data are they addressing with this information?
  3. Using the graph of the interaction between Working Alliance and Self-Disclosure on Expertness ratings as a guide, draw another graph that presents the same data in a different way.

Horowitz, et al., 2007

Horowitz, J. L., Garber, J., Ciesla, J. A., Young, J. F., & Mufson, L. (2007). Prevention of depressive symptoms in adolescents: A randomized trial of cognitive-behavioral and interpersonal prevention programs. Journal of Consulting and Clinical Psychology, 75(5), 693-706.
  1. Given the core assumptions for ANCOVA (both statistical and conceptual), do you think these authors make a good case for including pre-treatment depression scores as a covariate? Why or why not? (See lecture08 on ANCOVA.)
  2. The author's third moderation hypothesis (c) expected to see a stronger effect for the interpersonal program on depressive symptoms if the participant had higher sociotropy scores. Does the graph of the interaction (Figure 3, p. 700) appear to support that hypothesis?
