Frequent nonprescription stimulant use and risky behaviors in college students: the role of effortful control

Prescription Stimulant Use and Associated Risk Factors for Non-oral Use among 10 to 18 Year Olds

Non-medical use, especially non-oral use, of prescription stimulants is a public health concern. This study analyzed data from the National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS). Users (n = 723) were categorized as oral medical only users (n = 330, 45.6%), any oral non-medical users (n = 270, 37.3%), and any non-oral users (n = 123, 17.0%). The associations between patterns of stimulant use and risk factors were examined using logistic regression. Of the 123 any non-oral users, 79 reported using stimulants intranasally and orally, which was the most prevalent pattern of non-oral use. Among any non-oral users, the most common source of stimulants was from school (63.4%). Non-oral users primarily used stimulants to get high (74.4%) compared to 27.1% among other users. Negative consequences significantly associated with any non-oral use but not with oral non-medical use included needing stimulants to "feel ok," having trouble with teachers, bosses or friends due to stimulant use, and having anxiety and depression symptoms. In this study, non-oral use of prescription stimulants was associated with additional risks of adverse mental health outcomes compared to medical only use and other forms of non-medical use. Stimulant non-oral use interventions should emphasize the risks of intranasal use of stimulants.

Attention-deficit/hyperactivity disorder-specific stimulant misuse, mood, anxiety, and stress in college-age women at high risk for or with eating disorders

OBJECTIVE

To examine the misuse of attention-deficit/hyperactivity disorder (ADHD)-specific stimulants in a college population at high risk for or with clinical or subclinical eating disorders.

PARTICIPANTS

Four hundred forty-eight college-age women aged 18-25 at high risk for or with a clinical or subclinical eating disorder.

METHODS

Participants completed assessments of stimulant misuse and psychopathology from September 2009 to June 2010.

RESULTS

Greater eating disorder pathology, objective binge eating, purging, eating disorder-related clinical impairment, depressive symptoms, perceived stress, and trait anxiety were associated with an increased likelihood of stimulant misuse. Subjective binge eating, excessive exercise, and dietary restraint were not associated with stimulant misuse.

CONCLUSIONS

ADHD-specific stimulant misuse is associated with eating disorder and comorbid pathology among individuals at high risk for or with clinical or subclinical eating disorders. Screening for stimulant misuse and eating disorder pathology may improve identification of college-age women who may be engaging in maladaptive behaviors and inform prevention efforts.
