Change in Past 6 Month Relapse Prevention/Protective Behaviors Scale |
Measures the use of relapse prevention strategies and protective behaviors related to stimulant medication misuse. A score of "0" indicates that a given strategy did not occur and a score of "1" indicates that it did occur. Items were summed to create a scale summary score of overall number of unique relapse prevention/protective behavior strategies that occurred in the past 6 months (min=0, max=28). Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Past Year Prescription Stimulant Norms Rating Form |
Assesses the perceived percentage of students who have misused prescription stimulant medication in the past year. Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Current Semester/Quarter Motivated Strategies for Learning Questionnaire (MSLQ) |
A 19-item abbreviated version of the Motivated Strategies for Learning Questionnaire was used to measures the use of different types of learning strategies and academic motivations during the current semester/quarter. Response options ranged from 1=Not at all true of me to 7=Very true of me. Mean scale scores were computed and change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Cumulative and Last Semester/Quarter Grade Point Average (GPA) |
Participants report their cumulative and previous semester/quarter GPA. Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Past 6 Month Non-Medical Use of Prescription Stimulant Medication Frequency |
Assesses frequency of non-medical use of prescription stimulant medications. Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Tobacco, Alcohol, Prescription Medications, and Substance Use/Misuse Brief Screen/Assessment Tool (TAPS Tool) |
Assesses problematic use of tobacco, alcohol, prescription, and illicit drugs over the past year and 3 months. Response options included: 0= Never, 1= Less than Monthly, 2= Monthly, 3= Weekly, 4= Daily or Almost Daily. Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) - Stimulants Only |
Measures past 3 month non-medical use of prescription stimulants and associated negative consequences. Items were summed to create a scale summary score where higher values indicated more problematic use in the past 3 months (min=0, max=40). Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Past 6 Month Prescription Stimulant Use Consequence Questionnaire |
Assesses negative consequences associated with prescription stimulant misuse over the previous 6 months. A score of "0" indicates that a given consequence did not occur and a score of "1" indicates that it did occur. Items were summed to create a scale summary score of overall number of unique consequences that occurred in the past 6 months (min=0, max=19). Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Past 6 Month Daily Drinking Questionnaire |
Assesses typical alcohol consumption over the course of a typical week. Responses for number of drinks consumed each day of a typical week were summed to create a summary score of total number of drinks consumed over a typical week. Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |

Change in Past 6 Month Rutgers Alcohol Problem Index |
Measures negative alcohol-related consequences experienced over the past 6 months. A score of "0" indicates that a given consequence did not occur and a score of "1" indicates that it did occur. Items were summed to create a scale summary score of overall number of unique consequences that occurred in the past 6 months (min=0, max=26). Change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 6 months minus value at baseline and the value at 12 months minus the value at baseline). |
