This study investigates the relationship between the acceptance of the presuppositions of neurolinguistic programming (NLP) and the level of subjective well-being (SWB), psychological immunity, and assertive communication. The results provide evidence that acceptance of the presuppositions represent a way of thinking that is positively associated with SWB and it is also positively related to psychological immunity. However, no association was found between the acceptance of the presuppositions and assertive behaviour which may suggest that there is a gap between conceptual acceptance and its practical realization.
