92 PERSONALITY TYPES AND WORK BURNOUT AMONG POLICE OFFICERS IN ANAMBRA STATE R.N. Ugokwe -Ossai , Ph.D and Valentine A. Ucheagwu Abstract This study investigated the contributions of personality trait types to work burnout among police officers in Nigeria. This study involved (40) female and sixty-five (65) male police officers incidentally sampled from (3) police station in Anambra State. Their ages ranged between 24-50 years, with M age of 42.03 and SD age of 3.68. Big Five Personality Inventory (BF) and Maslach and Jackson (1986) respectively were used as instruments of data collection. Focused sample survey design were employed while repeated multivariate measure was used in data analysis. The result of the study showed significant differences among personality types on emotional exhaustion (EE) and Dehumanization (DH) subscales of the Burnout Inventory. On pairwise comparison, it was shown that the differences only existed between neuroticism and other personality types (extraversion, agreeableness, conscientiousness and openness) respectively. Discussion and recommendations were made in line with the result, obtained. Introduction Personality over the years had got wide publications as a result of its study on implications of numerous psychological disorders, coping mechanisms, adjustment to stress and response to pharmacotherapy as well as psychotherapy. Thus it is a gain saying that personality is a super ingredient in the formation and living of one’s life. Alport (1937) defined personality as the dynamic organization within the individual of those psychophysical factors that determine his unique adjustment to environment. Larsen and Buss (2002) defined personality as the set of psychological traits and mechanisms within the individual that are organized and relatively enduring and that influences his or her interactions with and adaptations to the environment. Because of the importance of personality to psychology, numerous theories and typologies of personality including trait personality factors had been designed. These typologies thus help researchers, employees and clinicians in determining the type of the individual before them, what he can do, and what he cannot and how to help him (for clinicians)/how to place him on job (for employee selection). Numerous studies have been done on the roles of personality in diverse areas of psychology, life and adjustment. Cartbonel, Moorhead, & Megargee (1984) investigated the degree to which individual scale and multivariate combinations of scale on the MMPI and California Psychological Inventory (CP) could predict criteria of adjustment in prison. Participants included 1,313 inmates at a federal correctional institution who were admitted over a 2 year periods. The criteria of adjustment were ratings made by custodial personnel, work supervisors and teachers as well as disciplinary infractions, days in disciplinary segregation and days in seek call. The result however showed that neither the MMP nor CPI scales nor weighted linear combinations therefore provide enough accuracy to be used alone for individual actuarial prediction. On another note, Swagler and Jome (2005) examined the effects of personality in Taiwan. The study explored how personality factors and acculturation influence the cross cultural adjustment process of North American sojourning in Taiwan. The result of the study revealed that grater psychological adjustment to life in Taiwan was related to less neuroticism, greater agreeableness, greater conscientiousness and Multidisciplinary Journal of Research Development Volume 15 No 5 September, 2010
