Flow is a state of complete immersion in an activity, and is most often experienced when working on a task where difficulty matches the skill a person has for solving that task. The goal of this study was to examine how certain personality traits relate to flow disposition, also known as flow proneness. We were also interested in examining whether the predictors of flow proneness differ between the contexts of job and leisure time. Using an online survey via snowball method, we obtained the self-reported results of 273 participants. We used the BFI for the Five-Factor model personality traits, DASS21-A scale for Anxiety, CFQ for Distractibility and SFPQ for Flow proneness in both contexts. We performed two hierarchical regression analyses, one for each context flow is experienced in, and used the same blocks of predictors in both: the first consisted of control variables age and gender, the second of the Five-Factor model personality traits and the third of narrow traits Anxiety and Distractibility. Results show that a total of 32% of work flow proneness variance was explained, and the statistically significant positive predictors were age, extraversion and consciousness, while negative predictors were openness and anxiety. We explained 41% of leisure flow proneness variance, with age and consciousness as positive predictors, and neuroticisim and anxiety as negative predictors.
