Alcohol Motives |
Using the past six months as a time reference, participants will be asked about their motivations to use alcohol. Twenty items for each substance will assess motives for using alcohol, such as "to be sociable" and "to forget about your problems" on a 5-point scale ranging from (1) almost never/never to (5) almost always/always. |

Alcohol Expectancies |
Alcohol expectancies will be measured using a 7-point scale ranging from (-3) strongly disagree to (3) strongly agree. Items will assess how likely a variety of alcohol-related consequences will be experienced in the next few months. For example, items, be worded specifically for alcohol use, such as "I will feel badly about myself because of my drinking." |

Alcohol Willingness |
Response options for willingness items will be on a 7-point scale ranging from (1) strongly disagree to (7) strongly agree. Willingness to use alcohol will be measured to assess participants? willingness to 1) drink once or twice in two hours; 2) drink 3-4 times in two hours; and 3) drink 5+ times in two hours. Willingness to use marijuana and COMBINE will be assessed individually with four items asking their willingness to use marijuana/COMBINE occasionally, regularly, weekly, and daily. |

Alcohol Norms |
Perceived norms of drinking for the past six months will be measured using the DDQ using closest friend as a referent. To assess peer injunctive norms of alcohol use participants will be asked to indicate how acceptable their closest friends would find of a list of situations (e.g., drinking enough alcohol to pass out) using a (1) strongly disapprove to (7) strongly approve scale. |

Parental Communication |
Parental communication about alcohol, nicotine, and marijuana use, COMBINE, and alcohol consequences will be assessed separately for parent and teen. Participants will be asked whether their parent discussed these topics (yes/no) with them within the past six months. Items include topics such as "the importance of not being pressured to drink to fit in" and "how marijuana works in the body." |

Primary |
Alcohol Use |
A standard drink definition will be provided: a standard drink consists of 12 oz. beer or wine cooler, 8.5 oz. of malt liquor, 4 oz. of wine, 3.5 oz. fortified wine, or 1.5 oz. of hard liquor. Typical weekly drinking: participants will respond to the Daily Drinking Questionnaire(DDQ; Collins et al., 1985) to indicate number of drinks consumed on each day of a typical week within the past six months. Participants will report maximum number of drinks consumed on an occasion within the past month and number of hours spent drinking on that occasion using the Quantity/Frequency/Peak questionnaire (QFP; Dimeff et al., 1999; Marlatt et al., 1998). Drunkenness will be assessed by asking how many times in the past month participants have gotten drunk, or very high from alcohol using a 6-point scale: (0) never to (5) 9 or more. Heavy episodic drinking will be measured for females and males separately, asking for number of times they?ve had 4/5, respectively, drinks in a row within two hours. |

Marijuana Use |
Frequency of use will be assessed by asking how often participants used marijuana during the past six months using a 7-point scale ranging from (0) never to (6) 40 or more times. |
Project years 1-2 |
|
Secondary |
Combined Use |
Frequency of combined use will be assessed for participants indicating marijuana and nicotine use with a single item: During times you used marijuana, how often did you also drink alcohol? using a 6-point scale ranging from (0) never to (5) 40 or more times. For participants that indicate their peak drinking occasion a follow up question will assess whether marijuana or nicotine was also used(yes or no). |
Project years 1-2 |

Secondary |
Consequences of Alcohol Use |
Alcohol-related consequences (e.g., said or done embarrassing things, blackout) from the past six months will be measured using the established Brief Young Adult Alcohol Consequences Questionnaire (BYAACQ; Read, Kahler, Strong, & Colder, 2006). Response options will again be measured on the same a 7-point scale as Combined Use. |
Project years 1-2 |
|
Secondary |
Nicotine Use |
Frequency of use will be assessed by asking how often participants used nicotine products (tobacco, vaping, snuff) during the past six months using a 7-point scale ranging from (0) never to (6) 40 or more times. |
