The study was designed to evaluate aggressive tendency in taxi drivers who were involved in repeated traffic accidents. The author selected 86 taxi dirvers from a taxi company in Pusang, whose education was between 9 to 12 years, Their career in
driving
were longer than five years. The rate of response to the questionaires was higher than 90 percent. The accident was defined as any accident that incurred at least 100,00 won worth of material damage or injury to person. The subjects were divided
into
two groups: high accident group was composed of subjects who have been in three or more traffic accidents during his career in driving, and low accident group, in nor or one traffic accident.
Aggressive tendency was measured by means of Hostility Guilt Inventory of Buss and Durkee (BDHI). Irritability-Depression-Anxiety Scale of Snaity(IDA) and Symptom Checklist-90-R of Derogatis(SCL-90-R). Correlation coefficients were calculated
between
frequency of the accidents and the scores of subscales of the above instruments: means of the subscales of the high and low accident group were compared using student's t test. Discriminant function analysis was attempted to discriminate between
the
high and low accident groups.
@ES The results were as follows:
@EN 1) Frequency of traffic accident was not correlated with age and driving career.
2) Frequency of traffic accident was positively correlated with total score and motor component of BDHI, total score of IDA and global index of SCL-90-R respectively.
3) High accident group had significantly higher means of total score, scores of motor component and attitudinal component of BDHI, total score and score of irritability of IDA and score of interpersonal sensitivity and score of interpersonal
sensitivity and global index subscales of SCL-90-r as compared to low accident group.
4) Discriminant function analysis between high and low accident group yielded nine significant variables: those whith positive standardized canonical discriminant function coefficients were motor component(BDHI), irritability outwards(IDA),
depression(IDA) guilt(SCL-90-R). positive symptom total(SCL-90-R) and positive symptom distress index(SCL-90-R) ; and those with negative coefficients were indirect hostility(BDHI), irritability inwards(IDA) and additional items(SCL-90-R), With
these
nine variables, high accident group was discriminated accurately in 81.8%, and low accident group, in 65.4%. The rate of 'grouped' cases correctly classified was 74.6%.
From these results it was suggested that action-oriented outward aggression and poorer control of hostility were significantly correlated with repeated traffic accident, and also the high accident group was characterized by higher outward
aggression and
severer general psychopathology.
