Reliability and validity of the Korean version of the temperament and character inventory

Objective: It has been suggested that some internet users spend so much time on the internet that their personal and/or professional lives suffer. This study compared the temperament and character of problematic internet users (PIU) with that of problematic drug users (PDU) among Korean adolescents and aimed to examine the personality characteristics of adolescents with internet use problems. Method: We enrolled participants from high schools (n = 487), internet cafés (n = 89), and an adolescent-substance abuse consultation office (n = 45). All subjects were assessed using the Korean Internet Addiction Scale (KIAS), the Korean Adolescent Drug Addiction Screening Test-2 (KOADAST-2), and the Korean version of the Temperament and Character Inventory (K-TCI). Subjects were classified into the following four groups based on the KIAS and KOADAST-2 results: normal controls, pure PIUs, pure PDUs, and dual problematic users. Differences in the subscale scores on the K-TCI were analyzed by group. Results: Scores for Reward dependence (RD) were significantly lower in pure PIUs than in pure PDUs (13.85 ± 4.07 versus 15.44 ± 3.56, p < 0.05). Scores for SelfDirectedness (SD) were lower in pure PIUs (18.21 ± 6.90) and pure PDUs (18.22 ± 6.03) than in normal controls (20.88 ± 6.60), although the scores did not differ significantly between pure PIUs and pure PDUs. Scores for Cooperativeness (C) were lower in pure PIUs than in normal controls (23.97 ± 7.02 versus 26.57 ± 6.67, p < 0.05). Conclusions: The results of this study suggest that PIUs are more socially insensitive and that they may experience more inter-personal problems than PDUs.

“…In accordance with the results of previous studies, those individuals who reported more than 21 points on the BDI or 22 points on the BAI were also excluded. The Korean version of the Temperament and Character Inventory (TCI) was used to assess the personality traits [28] . The TCI is a self-rating instrument of yes/no answers designed to evaluate the 4 personality dimensions of temperament -novelty seeking (NS), harm avoidance (HA), reward dependence (RD) and persistence (P), and the 3 character dimensions of self-directedness, cooperativeness, and self-transcendence [7] .…”

Recently, there has been growing enthusiasm for exploring biological approaches to personality, especially in the area of genetic research into the identification of those genes responsible for particular personality traits. The aim of this study was to investigate the association between the serotonin transporter-linked promoter region (5-HTTLPR) polymorphism and personality traits. We recruited 211 unrelated, normal subjects. The Korean version of the Temperament and Character Inventory (TCI) was used to assess certain personality traits. From blood samples taken from the subjects, DNA was isolated using standard techniques and the 5-HTTLPR polymorphism was genotyped by means of polymerase chain reaction and electrophoresis. We classified the subject into the s/s, s/l, and l/l groups according to their genotype. The differences in the temperament factors of the TCI between group S (s/s genotype) and group L (s/l + l/l genotype) were assessed, after the inclusion of gender and age as covariates in the analysis of variance. After controlling for gender and age, there were no associations between the harm avoidance, novelty seeking, and reward dependence scores and the genotypes. However, the persistence score of group S was significantly higher than that of group L. Our results suggest that the 5-HTTLPR polymorphism may be associated with the persistence score of the TCI in a normal Korean population.
