Most existing research and theory have concerned spirituality as a trait, an individual difference that is presumed to be relatively stable across time and situations. The present study examined the state variability of spirituality: How does spirituality vary within an individual? Every day for two weeks, 127 participants provided measures of the strength of their spiritual beliefs and other measures of psychological states including, self-esteem, depressive thinking, and self-focused thinking, and they described the events that occurred each day. Multilevel random coefficient modeling analyses found that at the within-person level, spirituality was positively related to daily positive events and was positively related to daily reflection about the self, i.e., adaptive self-focused attention. Participants also provided dispositional (trait) measures of the same constructs, and trait spirituality was positively related to agreeableness, conscientiousness, and reflection, and was negatively related to rumination. Overall, the results suggested that it is useful to distinguish state and trait spirituality and that at both level of analysis, spirituality is associated with beneficial intra- and interpersonal characteristics.
