The data presented in this article examine the relationship between the subcomponents of emotional intelligence (emotional perception and expression, emotional facilitation of thinking, emotional understanding and emotional management) and the stages of change (pre-contemplation, contemplation, action and maintenance). The final data were obtained from 429 Malaysian inmates (374 male and 55 female) recruited from eight Malaysian prisons in four different zones. The two instruments used were the Self-Rated Malaysian Emotional Intelligence Scale (SRMEIS) and the University Rhodes Island Change Assessment Scale (URICA). Both instruments underwent expert validation through construct and test-retest validity. The researcher randomly distributed a total of 550 questionnaires, of which 429 were accepted and 121 were rejected due to missing data and outliers, resulting in 78% of participants providing data that could be used in the analyses. All participants were informed of the confidentiality of their data, and their participation was voluntary. SPSS and Excel files are provided as supplementary material.
