Research relating to illicit use of prescription stimulants (IUPS) has, for the most part, focused on describing behaviors of IUPS. However, there have been few attempts to measure IUPS in a consistent manner or determine how to best predict IUPS in an effective and concise manner. Data from Mississippi State University undergraduates (N = 703) were analyzed to create two shortorm measures to predict lifetime IUPS. The data-driven shortorm consisted of 15 items and 5 factors, and accurately classified 74.8% of participants as users versus non-users. The hand-picked shortorm consisted of 8 items and 5 factors, and accurately classified 84.6% of participants as users versus non-users. Results of this study can begin to provide information and possible tactics for briefly and quickly measuring risk for IUPS, particularly in applied settings, like university health centers or academic admissions. Future directions for research include testing these created shortorm measures with longitudinal data collection, validating the measures on different populations, and determining if these measures can accurately predict specific behaviors related to IUPS (e.g., diversion, IUPS within certain time frames).

Little research exists on gender differences regarding prevalence or perceptions of risk associated with college students’ misuse, illegal consumption, and diversion of prescription stimulant medications. Data from Mississippi State University undergraduates (N = 1,714) were examined for gender differences in illicit behaviors and related risk perceptions. Men were more likely to report consumption and diversion, but not more likely to report misuse of their own prescription stimulants. Overall, men reported lower risk perceptions associated with consumption of others’ prescription stimulants. This finding held true for legal and health risk perceptions for those uninvolved in diversion or consumption, for health risk perceptions for those who report consumption, and for social risk perceptions for those who report diversion. Although some analyses were underpowered, results help clarify how researchers define and measure these behaviors, determine possible relationships between risk perceptions and illicit use of prescription stimulant medications, and identify potential targets for intervention.

The frequency of illicit use of prescription stimulants (IUPS) was examined in relation to known risk factors. A hierarchical linear regression (N = 903) was used to evaluate self-reported past-year IUPS and demographic variables. Gender (p < .05), race (p < .05), and GPA (p < .01) were significantly associated with the frequency of past-year illicit use. However, Greek organization membership status, perceived ADHD symptoms and access to prescription stimulant medication were not significant individual correlates of past-year IUPS. Additional analyses were conducted on the user subgroup (n = 101) to determine whether these relationships were similar compared to the general sample. Among users, ASRS Inattention and Hyperactivity-Impulsivity Subscale scores were significantly associated with the frequency of past-year IUPS (p < .05), even after accounting for gender, race, and GPA. Interpretations of these findings and implications for future research are discussed.

Illicit use of prescription stimulants (IUPS) has become more common in the late adolescent and emerging adulthood populations. This study examined the impact of close friend and parent disapproval/approval on IUPS in college students. A sample of 903 college students (MAge = 19.23) completed a questionnaire assessing variables including lifetime IUPS (14.59% of sample), and perceived close friend/parent disapproval/approval of either academic or recreational IUPS. A 2 X 2 chi-square test of independence was used to analyze data regarding perceived close friend/parent disapproval/approval and IUPS. There were four primary findings. First, students were significantly less likely to report having engaged in IUPS if they perceived close friend (CHI2 (1) = 55.99, p < .001) or parent disapproval (CHI2 (1) = 31.99, p < .001) of IUPS for academic purposes. Second, students were significantly less likely to report having engaged in IUPS if they perceived close friend disapproval of IUPS for recreational purposes (CHI2 (1) = 24.38, p < .001). Third, students were significantly more likely to report having engaged in IUPS if they perceived close friend approval (CHI2 (1) = 51.17, p < .001) and parent approval (CHI2 (1) = 7.87, p = .005) for academically-motivated IUPS. Fourth, students were significantly more likely to report having engaged in IUPS if they perceived close friend approval for recreationally-motivated IUPS (CHI2 (1) = 33.86, p < .001). Future researchers should focus on conducting longitudinal studies to confirm if perceived close friend and parent approval function as risk factors for IUPS and if disapproval functions as a protective factor. Future research is also needed to help identify whether student perceptions of disapproval and approval are accurate (i.e., do close friends and parents really approve or disapprove of IUPS?). Finally, investigators should work to assess whether increased perceptions of disapproval can function to reduce level of IUPS (i.e., not just lifetime prevalence) and whether increases in perceived approval function to exacerbate IUPS. Results of these kinds of research efforts would better inform whether psychoeducational interventions should target decreasing approval and increasing disapproval perceptions in order to both prevent and reduce IUPS behaviors.
