Text in English / There is increasing reliance on youth mentoring in South Africa to help the young person better negotiate life's difficulties. Within the framework of Social Cognitive and Social Learning theories, mentoring is viewed as a learning process in which modelling, scaffolding and cooperative dialogue are key to behavioural change and improved academic performance. However, little research has assessed the efficacy of South African mentoring programmes. This study aimed to examine the effect of the Educhange Research Foundation mentorship programme on the behaviour and academic performance of mentees over a six (6) month period. Mentees in Grades 9 to 12 (n = 18), parents/guardians (n = 18), and mentors (n=19) participated in the study. Parents/guardians reported significantly decreased numbers of behavioural problems (Z = -2.087, p = .037) amongst mentees but academic performance fell significantly (Z-3.661, p=.000). The variability in reports of behavioural change is accounted for by using Social Cognitive and Social Learning constructs including the conditions under which modelling took place as well as expectancy bias and the quality of cooperative dialogue. / Psychology / M.A. (Psychology)
