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.
- How many '
**cells**' in this study?
What are each of the **predictors** and their levels?
- "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?
- 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.
- 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.)*
- 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?
