Murray State Theses and Dissertations


This study gathered data using archival clinical files from the Murray State University Psychological Center, which provides psychological services to students, faculty, staff, and community members. The majority of the participants for the sample consisted of Caucasian (93%) males (60%) seeking an assessment (N = 76). Measures of externalizing behaviors and attentional problems were gathered from the Child Behavior Checklist (CBCL), and a measure of general cognitive ability (GAI) was gathered from the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). It was hypothesized that the relationship between impulsivity and externalizing behaviors would be more pronounced when intelligence is lower. While a correlational analysis confirmed that attentional problems did predict externalizing behaviors in children (p< .001), the moderation analysis was not significant, indicating that intelligence did not play a significant role in the relationship between impulsivity and externalizing behaviors.
