This study examines correlates of possession trance among cultures in sub-Saharan Africa. Several variables were tested (including community organization, marriage form, family form, and settlement pattern) but only a few were related to possession trance. Results indicate that the presence of slavery, stratification, and role and structure differentiation are significantly associated with possession trance.

This study examines correlates of trance and possession in pre-industrial societies. Results suggest that the presence of trance/possession is associated with subsistence, number of jurisdictional levels, and community decision-making.

This article offers a detailed analysis of neurophysiological processes involved in altered states of consciousness. Cross-cultural hypotheses concerning altered states of consciousness are tested.

This book investigates possession and possession-trance. While the author focuses on a case study of Haiti, there are also a handful of cross cultural tests performed. Results suggest that societal complexity is associated with belief in possession-trance, rather than possession alone.

A previous study conducted by Singh (2017) investigates why and how features of shamanism have culturally evolved, one such feature being shamanistic trance. However, the authors of this article argue that Singh fails to distinguish between different types of shamanistic trance. They find that possession trance, as compared to trance without possession, is primarily dominated by females and found in complex societies.
