The sample comprises 628 social science students from a Greek university. Path analysis is used to explore associations and interactions among the variables. The results show that academic procrastination and psychological well-being mediate the relationship between defense styles and approaches to learning, indicating the expected direct and indirect effects. Defense styles are directly related to approaches to learning. Mature defense styles are associated with learning through psychological well-being in a positive way, and immature defense styles are associated with learning through academic procrastination in a negative way. This study supports the current line of research in associations between defense styles and learning and the importance of linking mental health variables with learning.
