Abstract

The present study examined the accuracy with which police officers identified the types of questions asked during investigative interviews with alleged child abuse victims. Factors affecting their accuracy were also explored. One hundred and twenty Korean police officers were asked to classify 50 questions into one of five categories (invitations, facilitators, directives, option-posing and suggestive prompts). The overall accuracy rate was 65.6%; invitations were correctly classified most often (85.5%) whereas suggestive questions were least accurately identified (42.3%). Police officers tended to overestimate their use of invitations by incorrectly identifying directive questions as invitations. Suggestive questions were mistakenly identified as option-posing questions (22.2%), directive questions (15.1%), and even invitations (5.6%). Being trained to use the NICHD Protocol was the only factor significantly predicting higher accuracy.

Differences in presenting alibi and evidence by day and time

Abstract

The current study aimed to investigate the frequency differences in presentation of alibi and evidence by factors ̒day̓ and ̒time̓. We analyzed the frequencies of presenting alibis, physical evidence and witness evidence, and investigated the base rate by day (weekday / weekend) and time. A total of 282 respondents participated in this study through self-report online questionnaires. Participants were randomly assigned to one of 8 conditions that consisted of either the day (Tuesday / Saturday) and the time (3:00 / 9:00 / 15:00 / 21:00), and then they were asked to generate their alibis (location), physical evidence, and witness evidence to prove their innocence from mock robbery that they did not commit. Chi-square test was utilized to verify differences in the evidence reported by participants for certain day and time. In addition, binary logistic regression analysis was used in order to investigate the effect of day and time on the evidence. As a result, the day influenced whether family members witness evidence was reported and the time influenced all types of physical and witness evidence. In other words, people are most likely to report the witness evidence with the weakest reliability on weekend, and believable physical and witness evidence were least often reported at 3am in which crimes are most frequent. This study shows that a perfect alibi and evidence to prove innocence in the investigation process may not be possible. Finally, the limitations of the present study and suggestions of subsequent study were discussed.

A Validation Study of Two Factor Model: Focused on Korean Adolescents

Abstract

This study began with a study of the usefulness of a two-factor model consisting of the internalized and externalized measures of PAI, which were found through the study of Ruiz and Edens (2008). Based on the previous study of Ruiz et al. (2008), we examined the internal structure of the PAI-A scales for Korean adolescents and verified them with 11 clinical scales and two additional measures of SUI Scale and AGG scales. For this purpose, aged 14 to 21 adolescents conducted PAI-A at a reformatory and a high school in Seoul. As a result, the cronbach's α value of the PAI-A total scale and the subscale was found to be generally adequate except for some scales. Results of correlation analysis of 13 scales, the similar scales showed a high correlation and the low relevant scales showed a low correlation. In exploratory factor analysis, the distinction between internalizing and externalizing factors in Korean adolescents was different from the of the two factor model of Ruiz et al. (2008). Moreover, the BOR and PAR scales of PAI were classified as externalizing scale, but the BOR and PAR scales of were classified as internalizing scale in PAI-A. In addition, confirmatory factor analysis revealed that the two - factor model was not suitable. These results indicate that the PAI two-factor model is not suitable for PAI-A results in Korean adolescents, and this study attempted to find a two-factor model suitable for Korean adolescents.
