This was a correlation study exploring the relationships between scores on various dimensions within and across different exercises in the leadership assessment and development centre (LADC) of an auditing firm in Johannesburg. The study specifically aimed at investigating the discriminant and convergent validity of the LADC. LADC ratings collected from a sample of 138 were analysed using a Pearson Product Moment Correlation (r) and principal component analysis (PCA) was conducted to discover the main dimensions or constructs. Twenty one dimensions were measured using six different exercises in the LADC. The large correlations found in the study showed lack of discriminant validity amongst the majority of different dimensions measured in same exercises whilst, the PCA showed some convergent validity among various dimensions measured across exercises for the LADC. Lastly, the findings of the principal component analysis (PCA) supported a two-factor structure, indicating that assessors are able to differentiate between interpersonal and performance-related dimensions. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology)
