A scoring research on application of kinetic house tree person test on college students / 中华行为医学与脑科学杂志

ABSTRACT

Objective The kinetic house tree person test has many advantages compare to traditional psychometrics,but also some limits such as scoring subjectively and ambiguous.This research attempted to develop a reliable scoring system.That can distinguish college students with emotional disorder from normal college students by employing kinetic house tree person (KHTP) drawings.Methods 143 College students were invited to partake in the research KHTP drawings,the Beck Depression Inventory Ⅱ (BDI-Ⅱ),the Beck Anxiety Inventory (BAI) were administered to the subjects.Undergraduates with a BDI score of ≥ 14 or a BAI score of ≥8 were classified as the clinical group,while those with a BDI-Ⅱ and a BAI score are minimal were classified as the controis.The researcher and an expert studied and analyzed the KHTP drawings Manual,filtrate 35 indicators correlate to emotional disorder,and then researcher make standard for evaluation of every indicator.The standard for evaluation were then revised by the researcher and another rater then finalized by the expert.Results The results showed that 35 indicators correlate to emotional disorder were found,and there were significant differences in facial expressions (x2 =19.109,P＜0.01) and actions (x2 =13.341,P＜ 0.01) between clinical group and normal group.The Pearson coefficient of concordance showed that the inter-rater reliability and inner-rater reliability was consistent(r=0.932,r=0.913,P＜0.01).The t-test was employed to verify the discriminant validity between the clinical and control groups.The result showed that a significant discriminant validity was found with the scoring system developed in this research(t=14.890,P＜0.01).Conclusion The scoring system developed from this study has good inter-rater reliability,inner-rater reliability and discriminant validity.
