Time log data (time-spent and adjective evaluations), a six question survey about time management attitudes, and the Adult Self Expression Scale (behavioral and situational subscales), were examined regarding how well each predict GPA. This paper contains two studies. The first study uses canonical correlations to examine the natural relationships between GPA and the five sets of predictor variables. The second study is hypothesis testing with regard to four groups: males and females on academic probation, and males and females with high GPAs. The effects of academic probation and gender on the same four sets of variables are examined: time spent on selected activities, adjective evaluations of activities, a six question survey, and the behavioral and situational dimensions of the ASES. The six question survey shows the strongest connection with GPA. The time log data, while not very compelling, shows promise for future research. Of all of the variable sets, the ASES is the weakest predictor of GPA. [The dissertation citations contained here are published with the permission of ProQuest LLC.
