Personality has been found to relate to an individual’s satisfaction and frustration of basic psychological needs. The present study aimed to extrapolate on previous work by examining the role of emotion crafting between two facets of personality (openness to experience and conscientiousness) and basic psychological needs. In the first part of the study a total of 116 participants completed a baseline survey, where personality was assessed. In the second part, participants responded two times a day (morning and evening) over seven days, where emotion crafting and basic psychological needs were assessed. A total of 115 participants completed the daily surveys. Emotion crafting showed a mediating effect for the relation between openness to experience and basic psychological needs, with no significant direct effect between them. Conversely, the relation between conscientiousness and basic psychological needs was implicated, however, with no mediating effect of emotion crafting. Most importantly, the results implicated the role of emotional tendencies in openness to experience, and possibly the lack of it in conscientiousness. As such, further research to uncover other plausible mediators were suggested. Emotion crafting proved to be significantly related to basic psychological needs in all models, possibly illustrating its broad usefulness.
