Stereotypy or automatically occurring behaviors, as commonly seen in children with autism spectrum disorder, can be divided into three main categories: self-injury, stereotypy, and aggressive behaviors. Researchers have suggested different intervention approaches to treat stereotypy, such as redirecting or replacing undesired action. This Delphi study was developed to determine high-ranking effective intervention methods. Most researchers have been studying stereotypy behaviors in children with autism with no real focus on gender. This study was also designed to assess the possible impact of gender on stereotypy behaviors to develop new interventions based on the patient's gender. Although some gender differences were found, no consensus was reached. During Round Three of this study, experts identified five different types of interventions that could be used on both males and females but there was a discrepancy, and not all interventions that were effective for males were also effective for females. Out of five total interventions, three were similar and two were different based on gender. In the final conclusion, experts could not reach a consensus regarding the impact of gender on stereotypic behaviors in males and females.
