Effects of information on perceptions of stimulant medication efficacy for treatment of attention-deficit hyperactivity disorder

A study on the perceptions of stimulant medications prescribed for children with attention-deficit hyperactivity disorder (AD/HD) was conducted. Students, enrolled in introductory level psychology courses at a midwestern university participated voluntarily in the study (N= 36). After viewing a video that simulated the feelings a child with AD/HD experiences, participants were randomly assigned to two treatment groups. The popular information group read an article on AD/HD similar to that which is most often presented to the public. This article included personal testimonials and lacked a discussion of side effects and areas where the medications have not been demonstrated to be efficacious. The scientific information group read a page of information that was compiled from the scientific literature and included both the positive effects, side effects, and areas where the medication has not been demonstrated to be efficacious. All participants then completed a questionnaire regarding their perceptions of the efficacy of the medications. A second scale measured participants' likelihood of recommending the use of stimulant medications for children with suspected AD/HD. Two 2×2 between-subjects ANOVA's were employed. There were main effects for the type of article that was read, but no main effects for gender of participant. No significant interactions were found. There were no differences found between the gender of participants and their perceptions of stimulant medications based on the reading material presented to them. However, the type of information presented to the participants did influence their view of the efficacy of stimulant medications. In addition, the type of reading material also influenced the participants' view of the safety and recommended use of stimulant medications prescribed for children with AD/HD.
