Student participants in group therapy were hypothesized to improve on three dimensions of behavior as a result of therapy. It was further hypothesized that improvement would be related to participant eye color, with dark-eyed persons demonstrating greatest improvement and lighter-eyed individuals demonstrating lesser improvement. Differences were also expected from Ss by program. Ss were 35 male and female master's level students in clinical, counseling, and educational psychology programs, ranging in age from 23 to 39 years. Dependent measures were collected before and after therapy with the Vriend and Dyer Scale, an instrument yielding three factors: Self Defeating Behaviors, Fully Functioning Behaviors, and Personal Mastery Index. The design utilized a 3 (eye color) X 2 (program) two-way ANOVA, fixed effects model. Significant main effects were found for Fully Functioning Behaviors: by eye color (p less than .002) and by program (p less than .03). No interactions or other main effects were found.
假设参加团体治疗的学生在治疗后行为的三个维度上会有所改善。进一步假设改善情况与参与者的眼睛颜色有关，深眼者改善最大，浅眼者改善较小。不同项目的学生之间也预期会有差异。受试者为35名临床、咨询和教育心理学专业的硕士研究生，男女皆有，年龄在23岁至39岁之间。在治疗前后使用弗里德和戴尔量表收集相关测量数据，该量表产生三个因素：自我挫败行为、完全功能行为和个人掌握指数。本设计采用3（眼睛颜色）×2（项目）双向方差分析固定效应模型。在完全功能行为方面发现了显著的主效应：按眼睛颜色（p小于0.002）和按项目（p小于0.03）。未发现交互作用或其他主效应。
