Personality traits were measured using a validated personality inventory which was the USMaP-i. A significant difference of mean personality traits score was found between the two groups. Medical students selected through interview had higher score in extroversion, conscientiousness, agreeableness and openness as well as lower score in neuroticism compared to non-interview group. This finding provides evidence on positive impacts of interview process on personality traits of future medical students. 2013 The Authors. Published by Elsevier Ltd.

Introduction Medical courses need applications of science with opportunities to contribute to the highest standard of patient care upon graduation as expected by society. In the process of determining of many highly qualified candidates to admit to a medical education program, there is a widespread concern for selecting students based on personality traits. Personality traits defined as predispositions to behave in ways that satisfy our basic and innate or natural self. A trait is a characteristic of a person that is enduring and generally remains stable after the age 25 to 30 and often described as consistent or repetitive patterns of a behaviour (Sheperd, 2007). A mixture of personality dimensions is necessary for medical students beside the process of learning, understanding and ability to gain the knowledge for Corresponding Author: Muhammad Az-zuhri Azman, Tel: +23 444747764 Email: Muhammad Az-zuhri Azman @gmail.com 1877-0428 2013 The Authors.

2282 Muhammad Az-zuhri Azman et al. / Procedia - Social and Behavioral Sciences 116 ( 2014 ) 2281 2285 them to be successful in their medical studies and eventually in medical profession (Ferguson, James, & Madeley, 2002; Griffin & Wilson, 2011). The Big Five Personality dimension has received tremendous attention in terms of understanding how personality can be used in the selection, training, performance management and impact on workplace behaviour (Griffin & Wilson, 2011). The Big Five factor model has been used intensively in research on the relationship between personality and workplace performance, and now widely used by a number of researchers as important predictors of academic performance. It is now acknowledged that personality traits can be grouped into five main traits which include Extroversion, Conscientiousness, Agreeableness, Neuroticism and Openness. The Big Five Personality dimension is a broad category of personality traits. Researchers do not always agree on the exact labels for each dimension, however a significant body of literature supporting this five-factor model of personality (Yusoff, Rahim, & Esa, 2010). If the traits features such as imaginative and insightful, and tend to have a broad range of interests then it will be categorized under the openness. Conscientiousness is commonly features include high levels of thoughtfulness, with good impulse control and goal-directed behaviours and also tend to be organized and mindful of details. The traits of extroversion include the characteristics such as excitability, sociability, talkativeness, assertiveness and high amounts of emotional expressiveness. The personality dimension of agreeableness includes attributes such as trust, altruism, kindness, affection, and other pro-social behaviours. Lastly the personality dimension of neuroticism includes attributes such as experience emotional instability, anxiety, moodiness, irritability, and sadness (Goldberg et al., 2006; Yusoff et al., 2010). There are three types of interviews that can be conducted which are traditional, unstructured interviews and structured interviews with objective scoring protocols (McDaniel, Whetzel, Schmidt, & Maurer, 1994). Among these type of interviews, structured interviews are more scientifically and ethically defensible than other types of interviews (Patrick, Altmaier, Kuperman, & Ugolini, 2001). The term structure for structured interview defined very broadly as any enhancement of the interview that is intended to increase psychometric properties by increasing standardization or otherwise assisting the interviewer in determining what questions to ask or how to evaluate responses (Campion, Palmer, & Campion, 1997). However, unstructured interviews appear as most commonly used among medical schools. This type has been characterized by a conversational, informal style, questions that are not specified in advance and also a lack of objective scoring criteria (McDaniel et al., 1994). Since 2009, the School of Medical Sciences University Sains Malaysia selects its students semi-independently from the Malaysian Ministry of Higher Education based on a structured interview (Yusoff, Rahim, Baba, & Esa, 2011). Recent studies have reported that the interview method able pick up candidates who pose a high level of resiliency toward the demanding and stressful medical education environment (Yusoff, Rahim, Baba, Ismail, & Esa, 2012; Yusoff et al., in press). This study aimed to explore whether the selection of prospective medical students based on the structured interview method able to pick up candidates with more favourable personality into the medical profession by comparing personality trait scores of medical students selected based on interview and noninterview methods. The authors hypothesized that medical students selected by an interview method had more favourable personality than medical students selected by a non-interview method. 2. Method A comparative cross-sectional study was conducted in the School of Medical Sciences, University Sains Malaysia (USM) Kubang Kerian, Kelantan involving two cohorts of medical students who were selected through interview and non-interview methods. The medical students are the first batch of students who were selected using our interview selection procedure. The students are the last batch of students who entered our medical school without undergo selection interview. This two group were taken as comparison to minimised the study environment exposure difference. Students who are repeating their study year were excluded from this study. There were 232 third year students and 223 fourth year students Participants were assured of their confidentiality of the responses. Sample size of 169 was estimated from calculation using Power and Sample Size Program version 3.0.14 for comparing means between two groups with the level of significance (α), 0.05 and the power of the study (1-β), 0.8

Muhammad Az-zuhri Azman et al. / Procedia - Social and Behavioral Sciences 116 ( 2014 ) 2281 2285 2283 based on pilot study by (Yusoff, Rahim, Esa, Aziz, & See, 2011). The personality inventory, USMaP-I, was designed to identify Malaysian students personality based on local cultures and values (Yusoff et al., 2010). It has 60 items that indicates five personality traits; extroversion, conscientiousness, agreeableness neuroticism and openness. It was validated in with multi-ethnic, multi-religion and multi-cultural sample with the Cronbach s alpha reliability value of 0.73 (Yusoff, Rahim, Abd Aziz et al., 2011; Yusoff et al., 2010). The Cronbach s alpha value for each dimension ranged from 0.634 to 0.831 (Yusoff, Rahim, Abd Aziz et al., 2011; Yusoff et al., 2010). Its internal consistency was stable across time and occasions (Yusoff, in press). Students were asked to rate each statement that describes their personality using a 5-Likert Scale response choice of very inaccurate = 0, moderately accurate = 1, neither accurate nor inaccurate = 2, moderately accurate = 3 and very accurate = 4. Based on the USMaP-i manual, it categorized each personality trait into low (total score between 0 and 14.4), average (total score between 14.41 and 33.6) and high (total score between 33.61 and 48) (Yusoff et al., 2010). Analysis of Covariance (ANCOVA) was used to compare the personality scores between the two groups. 3. Result There were 197 participants in the interview method group and 199 participants in the non-interview method group. Both group had more female than male students with majority were Malay and entered from matriculation pre-university program (Table 1) Table 1: Socio-demographic characteristics of interview and non-interview groups.

2284 Muhammad Az-zuhri Azman et al. / Procedia - Social and Behavioral Sciences 116 ( 2014 ) 2281 2285 b Bonferroni adjustment for 95% CI for difference There are significant differences on mean scores of all five personality traits between interview and noninterview groups after controlling the age, sex, race, entry qualification and parent educational status. 4. Discussion In this study, the interview group showed relatively significant higher on extroversion score after adjusting the age, sex, race, entry qualification and parent educational status. Individuals with high score in extroversion enjoy being with people, energetic, and often experience positive emotions as well as tend to be enthusiastic and action-oriented (Ferguson et al., 2002; Yusoff et al., 2010). These traits are considered as desirable traits for future medical doctors who will be treating patients in the society. Those doctors who enjoy with their career will be able to deliver the highest standard of patient care to the society. The interview admission method group also showed significantly higher mean score in conscientiousness trait. Medical students with high score in conscientiousness are at advantages because they will always avoid creating troubles and try to attain high level of success through purposeful and consistent planning throughout their study as well as future career (Ferguson et al., 2002; Lievens, Coetsier, De Fruyt, & De Maeseneer, 2002; Yusoff et al., 2010). Mean score of agreeableness traits was found to be significantly higher in interview group than the noninterview group. Individuals with high score in agreeableness have characteristics of being-cooperative, trusting, pleasant and sympathetic (Ferguson et al., 2002). Future medical doctors need these personality traits as agreeable people have an optimistic view of human nature and they believe people are basically honest, decent, and trustworthy (Yusoff et al., 2010). On top of that they will be in better place to work in team. Our data also showed significant higher mean score on openness for interview group. This finding indicates that the interview group had one of the most important central aspects of openness which is intellectually curious. Intellect people love to play with ideas, open-minded to new ideas and like to debate intellectually on issues (Ferguson et al., 2002; Yusoff et al., 2010). This personality trait is an important quality for good medical student as they are expected to continue their medical knowledge through their professional s life as medical keep on evolving. The non-interview admission method group had significant higher mean score on neuroticism traits than the interview group. Those who had higher neuroticism score had more tendencies to experience negative and disruptive emotion and feelings than those in the interview group. They tend to focus on their feelings states such as anxiety, anger, envy, guilt and depressed mood thus distracting their attention, concentration and focus on their learning tasks (Ferguson et al., 2002; Yusoff et al., 2010). As a medical student, neuroticism level should be low. Individuals who score low in neuroticism are less easily upset and emotionally stable well as tend to be calm under pressure and less frequent experiencing persistent disruptive feelings (Yusoff et al., 2010). On top of that, many studies reported that neuroticism is the best predictor of mental health (Goodwin & Friedman, 2006; Lahey, 2009; Nordin, Abu Talib, & Yaacob, 2009). This will further help them to later succeed as good doctors in future career pathway. 5. Conclusion and recommendation Our findings thus showed that interview group had higher mean score on extroversion, conscientiousness, agreeableness and openness but lower on neuroticism score compared to the non interview students. This finding suggests that the interview method was able to select prospective medical students with more desirable personality characteristics than the non-interviewed medical students. Thus interview can be as one of the selection method for medical schools Acknowledgements Our deepest appreciation to our Dean and Deputy Dean (Academic & Students Development) as well as academic office staffs who had supported and facilitates this study. We also would like to thank all medical students
