The goal of this study was to determine what undergraduate criminal justice students know about communication disorders. This study, using a well-designed survey, was conducted to obtain baseline data regarding criminal justice students’ knowledge and awareness of communication disorders. A convenience sample was obtained by recruiting undergraduate criminal justice students attending a Midwest university in the Fall 2019 Semester. Participants responded anonymously to questions involving a 6-point Likert-scale questionnaire provided electronically. The questions comprised of eight hypothetical scenarios involving an individual with a communication disorder. Each scenario contained two constructs (action and knowledge) which was used to assess the participants’ potential behavior towards individuals with communication disorders and general knowledge of communication disorders. Data was analyzed using SPSS. The results suggested undergraduate criminal justice students are not well-informed about various types of communication disorders. Significant positive correlations (p < 0.05) were found between “action” and “knowledge” constructs; indicating students have poor general knowledge and behavioral/interaction strategies regarding communication disorders. The results also revealed significant differences between knowing someone with a communication disorder and having previous work experience within the criminal justice system (p < 0.05). It was determined that having previous work experience and knowing someone with a communication disorder produced the highest level of knowledge and appropriate behavior towards individuals with communication disorders. The current findings provide support for increasing and improving education regarding communication disorders within the undergraduate criminal justice curriculum.
