Popis:	Nonlinear or discontinuous change was analyzed by applying a catastrophe shift model to data collected on the anxiety levels of Year 12 students immediately before and immediately after they received offers of university places. Students' anxiety levels were expected to be subject to rapid change from prearrival of university offers to postarrival of offers. This process is described, in catastrophe shift terms, as discontinuous or nonlinear change and can indicate a change in state rather than a linear change in degree. Significant differences were revealed in anxiety levels from prearrival of offers to postarrival of offers for Preference Groups 1, 2, and 3. Bimodality was also revealed, using analysis of variance (ANOVA); however, analysis using cubic regression indicated that only Preference Groups 1 and 2 demonstrated significant nonlinear change. These findings suggest that the use of cubic regression analysis to identify nonlinear change may reveal more complex changes than is indicated by...
