Abstract The study was conducted in a group of Polish students based on a two-factor model of religious insights. Subjects were examined using a Questionnaire of Religious Insights and several methods concerning aspects of individual functioning selected based on Socha’s model of spirituality as a symbolic adaptation to the human existential situation. In the first study, the relation between religious insights and both scales: Doubt and Quest, declared religiosity and religious orientation were assessed. In the study, the relation of religious insights and its scales: Doubt and Quest, and selected aspects of individual functioning: depression, various kinds of narcissism, epistemic motivation, and sensation seeking were tested. The obtained results confirmed the interdependence of the Doubt and several variables describing the psychological functioning of an individual: sensation seeking, epistemic motivation, and vulnerable narcissism. Quest measured by QRI was confirmed not to be related to variables concerning the functioning of the individual selected based on Socha’s model of spirituality as symbolic adaptation to human existential situation. This opens the question of its psychological nature, showing that neither personality nor epistemic motivation are related to it.
