The purpose of the present study is to examine the reciprocal relationship between procrastination and neuroticism depending on conscientiousness and negative life events within the scope of a non-recursive model. The study was carried out during the 2011-2012 academic year on 677 teacher candidates (363 females, 302 males) attending the Art and Design Faculty of Gazi University. The participants were administered the Personality Test Based on Adjectives (Bacanli et al., 2007), the General Procrastination Scale (cakici, 2003), and the Life Events Inventory (Ding, 2001). The results of this study indicated that there was a positive reciprocal relationship between neuroticism and procrastination, and that conscientiousness was negatively correlated with procrastination whereas negative life events were positively correlated with neuroticism. Also, the indirect effects of conscientiousness on neuroticism and of negative life events on procrastination were found to be statistically significant.
