Introduction: Cognitive distortion seems to be a potential force in shaping criminals and antisocial behaviour within an individual. Unfortunately there is no valid Malay psychometric instrument available to measure cognitive distortion in Malaysian settings, especially in prisons. There is an urgent need to have a valid and reliable Malay psychometric instrument to assess the cognitive distortion among Malaysians. Therefore, the present study aimed to validate “How I Think” Questionnaire into the Malay language (henceforth, HIT-M). Methods: A cross-sectional study was conducted among inmates (n= 150) incarcerated within two prisons in Peninsular Malaysia. The validation study commenced with Forward-Backward translations and was followed by content and face validities. Later, construct validity was
performed via Exploratory Factor Analysis using Principal Component Analysis. Varimax rotation was applied in order to optimize the factor loadings on the extracted component. Finally, reliability testing was
performed to determine the internal consistency of the items which was done using Cronbach Alpha coefficient method (α). Findings: Initial factor loadings resulted in 11 factors with a total variance of 74.1%. Next, factor analysis was repeated by extracting the items into a four factor structure parallel to the theoretical construct. Items with factor loadings above 0.40 were retained as acceptable factor loadings. After considering factor loadings, item correlation and content of items, the final version of HIT-M consisted of 24 items. The internal consistency of HIT-M was 0.90 which was considered good. Conclusion: HIT-M is a valid and reliable psychometric instrument to measure and assess cognitive distortion among Malaysians.
A review of the criminological literature indicates that some personality traits appear to develop and shape violent criminal behaviour. With this in mind, the present study was aimed to examine the personality profiles of Malaysian male murderers utilising the Alternative Five Factor Model (AFFM) constituting five personality traits: Activity, Sociability, Aggressiveness-Hostility, Impulsive Sensation Seeking, and Neuroticism- Anxiety. Methods: The present study was an observational cross-sectional study using a guided self-administered questionnaire. Items representing the five personality traits were assessed through the Malay version of Zuckerman-Kuhlman Personality Questionnaire-40-Cross Cultural Questionnaire (ZKPQ-M-40-CC). 71 male prisoners convicted of murder who are incarcerated in 11 Malaysian prisons were recruited. Descriptive item analyses were carried out to elicit the level of responses for each item in the ZKPQ-M-40-CC. Furthermore, the descriptive personality profiles using mean scores were performed. Results: The results indicated that the mean score of Activity (29.35, SD = 5.66) was higher than other personality traits. The mean score of Impulsive Sensation Seeking (21.65, SD = 6.48) and Aggressiveness-Hostility (21.65, SD = 6.48) were higher than the mean score of Neuroticism-Anxiety (17.96, SD = 5.51). Among the participants, 56.3% of them scored above the mean score (M = 26.54) for Sociability personality traits, which was the highest compared to other personality traits. 53.5% of the murderers scored equal or above the mean score (M = 6.48). Correlations among the five personality traits indicated several significant associations. Conclusion: In conclusion, the present study successfully identified the personality profiles of Malaysian male prisoners convicted of murder.
