description: This program of research had two related aims: (1) to explore the problem of student attrition in the context of an Australian higher education institution, and (2) to investigate the efficacy of peer-mentoring as a retention strategy. Participants in this program of research were students commencing first-year studies in the School of Applied Psychology across two cohort years: 1996 and 1997. In 1996, a classic pre-test/post-test experimental design was adopted, with students (N = 118) randomly assigned to either a peer-mentoring treatment group or a control group. In 1997, while a classic pre-test/post-test design was also adopted, all students from this year (N = 162) participated in the peer-mentoring program. Thus, it was intended that the 1996 control group would be utilised for comparison with both the 1996 and 1997 treatment groups. Students were surveyed pre- and post-intervention across a number of personal, demographic, and academic achievement (e.g., tertiary entrance rank, and grade point average) variables. Students’ academic integration, social integration, institutional commitment, and goal commitment were measured using the Institutional Integration Scales (adapted from Pascarella and Terenzini, 1980). Students participating in the peer-mentoring program also completed a range of measures in order to evaluate its efficacy. The first part of the research program focused on the measurement and prediction of student retention and academic performance. The results of confirmatory factor analyses indicated that a six first-order factor solution provided the most parsimonious explanation of students’ responses to the Institutional Integration Scales. The six Institutional Integration Scales demonstrated moderate to good levels of reliability, with results being comparable to those achieved in previous studies. The results of structural equations modelling analyses suggested that students’ peer group interactions influenced their interactions with faculty, and both of these factors, along with their faculty concern for student development and teaching, influenced students’ academic and intellectual development, which in turn influenced students’ institutional and goal commitments. These results were taken to indicate the potential value of peer-based processes in aiding students’ institutional and goal commitment and subsequently reducing levels of student attrition. Given that significant differences were found between the 1996 and 1997 cohorts on a number of pre-test measures and other key indicators, investigations regarding significant predictors of students’ re-enrolment into second year and their first year grade point average were conducted separately for the two cohorts. The results of logistic regression analyses indicated that students’ first year grade point average was the only consistent and significant predictor of their re-enrolment into the second year of study across the two cohorts. Multiple regression analyses revealed that students’ tertiary entrance ranks and previous university attendance were consistently significant predictors of their first year grade point average across the two cohorts. Equipped with a better understanding of the factors that affect student attrition and academic performance, as well as the relationship between those factors, the second part of the thesis focused on the efficacy of two formal, group-based peer-mentoring relationships in assisting first year students make a successful transition to university. However, given that significant differences were found between the 1996 and 1997 cohorts on a number of pre-test measures and other key indicators, it was not possible to evaluate the efficacy of the 1997 peer-mentoring program relative to either the 1996 peer-mentoring program or control group. Nevertheless, the 1996 treatment and control condition groups were found to be equivalent on pre-test measures and indices, and thus were able to be compared. Overall, the results of a series of one-way ANOVAs revealed that the 1996 peer-mentoring program was found to have a positive effect on enhancing students’ re-enrolment into second year, persistence intentions, academic performance and self-reported adjustment, which was consistent with the direction of findings in previous studies. However, for a range of reasons, the effect of the 1996 peer-mentoring program on a number of these variables was not strong enough to reach statistical significance. Although there were trends towards significant differences between the 1996 treatment and control groups on a number of variables (i.e., students in the 1996 peer-mentoring program evidenced higher grades in PB11002: Introduction to Cognitive and Biological Psychology; and PB11008: Research Methods and Statistics; as well as higher scores on the Peer Group Interactions scale than students in the control group), the only significant positive difference of the 1996 peer-mentoring program was the improvement of students’ academic performance in one first year subject (i.e., PB11006, Introduction to Research in the Behavioural Sciences). Finally, exploratory factor analyses and reliability analysis of a mentoring functions scale revealed strong support for the presence of one, highly reliable, general mentoring function. Both the 1996 and 1997 program participants’ ratings of the performance of this general mentoring function were significantly and positively correlated with their self-reported academic and intellectual development. In addition, the 1997 program participants’ ratings of the performance of this general mentoring function were significantly and positively correlated to their self-reported peer group interactions, institutional commitments, goal commitments, and persistence intentions.
