Gender violence is a problem of central relevance since its consequences are fatal and affect the world's population. Comprehensive sexual education (CSE) is considered a key tool to apply gender violence prevention (PGV) strategies. However, the adequate implementation of CSE depends largely on teacher training. Therefore, the objective of this chapter is to improve the understanding of psychoeducational materials on CSE and PGV intended for teachers. The role of causal connectivity of a material on general CSE and one specifically on PGV from a manual for secondary school teachers designed by the Ministry of Education of Argentina (2022) was analyzed. The results demonstrated the predominance of a low level of causal connectivity in both materials. Considering the role of causal connectivity, as a textual characteristic that facilitates comprehension, could optimize the development of CSE and PGV materials for teachers and, consequently, contribute to the training and implementation of CSE and PGV.
