MULTI-IMPULSIVITY WITHIN AN ADOLESCENT PSYCHIATRIC POPULATION

The primary purposes of this study were: (1) to determine if total sco res on the Psychopathy Checklist-Revised (PCL-R) are significantly rel ated to the number of impulsive behaviors a patient displays; (2) to d etermine if within a population of adolescent psychiatric patients the re exists a subgroup of individuals who display multiple impulsive beh aviors; (3) to determine if multi-impulsivity is a useful concept with in a female sample; and (4) to determine if the PCL-R is useful for me asuring behavioral impulsiveness in females. The current study extends past multi-impulsive research by: (1) studying adolescents from a res idential psychiatric facility; (2) the inclusion of enuresis as an imp ulsive behavior; (3) the inclusion of female patients; and (4) the use of the PCL-R, a behavioral checklist designed to measure psychopathic behavior. The results indicate that the total score on the PCL-R is s ignificantly related to the number of impulsive behaviors exhibited by a patient. The number of impulsive behaviors displayed was not relate d to a patient's age, IQ, length of present stay, educational placemen t or number of restraints per month. Multiple impulsive behaviors were evident in 88% of the adolescent patients and equally present in both the male (87%) and female (89%) subgroups. Male patients exhibiting t hree or more impulsive behaviors form a markedly different subgroup of multi-impulsive patients who scored significantly higher on the PCL-R . It is suggested that these patients may suffer from a true generaliz ed lack of impulse control. These results are consistent with and lend support to previous studies on the concept of multi-impulsivity.
