Text in English / This study was designed to determine whether a relationship exists between self-reported mindfulness, self-consciousness, adjustment and academic performance in first-year university students. Additionally, the study aimed to assess the predictive quality of mindfulness and self-consciousness towards emotional adjustment (adjustment disorder symptoms, depression and anxiety) and academic performance, and to further determine the contribution of mindfulness and self-consciousness on adjustment to the predictability of academic performance. First-year students (N = 290) at the Tshwane University of Technology (TUT) at the Pretoria West and Ga-Rankuwa campuses completed the selfreported mindfulness measure, Mindfulness Attention and Awareness Scale (MAAS) (Brown & Ryan, 2003), the Self Consciousness Scale- Revised (SCS-R) (Scheier & Carver, 1985), the Beck Depression Scale (BDI) (Beck et al., 1961) the Beck Anxiety Scale (BAI) Beck & Steer,1993) and the adjustment disorder checklist; based on DSM V, (Sadock, Sadock & Ruiz, 2014). Students’ year-end results for the first year of study were used to operationalize academic performance. Results of correlation analyses indicated a significant negative correlation between mindfulness and students’ emotional adjustment (adjustment disorder symptoms, depression and anxiety), a significant positive correlation between selfconsciousness and students’ emotional adjustment (adjustment disorder symptoms, depression and anxiety) as well as a significant negative correlation between adjustment disorder symptoms and academic performance. Multiple linear regression analysis was used to test whether mindfulness and self-consciousness significantly predicted students’ depression, anxiety and adjustment disorder symptoms. The results of the regression analysis indicated the two predictors explained 16% of the variance (F (1, 1773) = 29.66, P< 0.0001) (depression), 14% of the variance (F (1, 985) = 24.14, p < 0.0001) (anxiety) and 14% of variance (F (2, 292) = 23.87, p <0.001) (adjustment disorder symptoms). Furthermore, mediation analysis provided information regarding the impact of mindfulness and selfconsciousness on students’ academic performance. The impact of mindfulness and selfconsciousness on students’ academic performance (students’ marks) was found to be mediated by adjustment disorder symptoms. However, the Sobel test indicated a significant effect (0.03) for mindfulness and an insignificant effect (0.09) for self-consciousness. / Psychology / Ph. D. (Psychology)
