Changes in frequency of parent-child conversations about substance use |
Frequency of parent-child conversations about substance use will be measured at each timepoint using questions adapted from a measure assessing parent-child conversations about sex in Miller et al. (1998) "Family communication about sex: What are parents saying and are their adolescents listening?" |
Short-term (3 and 6 months); long-term (12 and 18 months) |
|
Primary |
Changes in quality of parent-child conversations about substance use |
Quality of parent-child conversations about substance use will be assessed by an audio-recording of a prompted parent-child conversation using an adapted version of the Family Assessment Task (FAsTask), which will be coded quantitatively. |
Short-term (6 months); long-term (12 months) |

Changes in parent-child conversations about substance use |
Parent-child communication about substances will be measured with an adapted version of the Targeted Parent-Child Communication about Alcohol Scale. Several dimensions are assessed including parental warnings about the dangers of drugs, advice for how to address drug situations such as offers or peer pressure, and articulation of rules and sanctions around drugs. Ten items are asked of the parent and child at each time point. Items are assessed on a six-point Likert scale from "Strongly agree" to "Strongly disagree". |
Short-term (3 and 6 months); long-term (12 and 18 months) |

Primary |
Changes in quality of family mealtime interactions |
The mean quality of mealtime interactions will be measured using various scales from the Iowa Family Interaction Rating Scales (IFIRS) coding system: Dyadic Interaction Scales, Dyadic Relationship Scales, Group Interactions Scales, and Parenting Scales. Observed behaviors from 3 video-recorded family meals will be assessed and scored on a 9-point scale. A higher score indicates coders observed a higher intensity and/or frequency of the construct in the video-recorded family meals. Each IFIRS scale is scored individually and the average across the 3 family meals will be reported. |
Short-term (6 months); long-term (12 months) |

Changes in child substance use expectancies (alcohol) |
Positive and negative expectancies about the affective, cognitive, and behavioral effects of alcohol use will be assessed with the Alcohol Expectancy Questionnaire-Adolescent Form, short version. The tool is comprised of 27 items, each with response options ranging from (1) Strongly Disagree to (6) Strongly Agree. Questions 6, 9, 17, 26 are scored in opposite direction before they are included in the scales. Scores are summed to create a total scale range from 27 - 162. A higher score on the scale indicates a greater belief that alcohol has desirable effects. |

Changes in child substance use expectancies (cigarettes) |
Positive and negative expectancies about the affective, cognitive, and behavioral effects of cigarette use will be assessed with the Positive and Negative Outcome Expectancies of Smoking scale. The tool comprises 12 items, each with response options ranging from (1) Strongly Disagree to (6) Strongly Agree. The tool has two subscales (positive expectancies, determined by 7 questions; negative expectancies, determined by 5 questions). Summary scores for both the positive and negative expectancies are created. Summary score values range from 0-7 for positive, 0-5 for negative expectancies. Higher score on positive expectancies scale indicates a greater belief that there are positive outcomes of smoking. Higher score on negative expectancies scale indicates a greater belief in negative consequences of smoking. |

Changes in child substance use expectancies (marijuana) |
Positive and negative expectancies about the affective, cognitive, and behavioral effects of marijuana use will be assessed with an adapted version of the Marijuana Effect Expectancies Questionnaire - Brief. The tool comprises three standalone subscales (Relaxation/Tension Reduction, Cognitive/Behavioral Impairment, Global Negative Effects) for a total of 27 items. Each item has responses ranging from (1) Strongly Disagree to (6) Strongly Agree. Scores for each subscale are calculated by averaging item scores within that subscale. Each subscale score range is from 1 - 6. Higher scores on each scale indicate greater expectations of Relaxation/Tension Reduction, Cognitive/Behavioral Impairment, and Global Negative Effects associated with marijuana use. |

Changes in child affiliation with substance-using peers |
Using an item from the Monitoring the Future study, children will be asked how many of their friends they think use substances. The item is repeated for each substance. |

Changes in child willingness to use substances |
Child willingness to use substances will be assessed through three items adapted from the measure combining intention and willingness originally developed for tobacco and amphetamines found in Gibbons et al. (1998) Reasoned Action and Social Reaction: Willingness and Intention as Independent Predictors of Health Risk. The three items will be asked for each substance. Each item has response options ranging from (1) Not at all likely to (6) Very likely. The second two items are reverse coded and the three items are averaged to create a behavioral willingness index that ranges from 1 to 6. Each substance is scored separately. A higher score indicates that the child is more willing to try the substance. |

Changes in child intentions to use substances |
Two items from the Youth Alcohol and Drug Survey will assess child's intention to use substances. The two items will be asked for each substance at baseline and each follow up timepoint. Each item has the response options (0) No, (1) Probably No, (2) Probably Yes, (3) Yes. Each item assessed individually, and each substance is scored separately. A higher score indicates greater intention to use the substance. |

Secondary |
Changes in pre/early-adolescent substance use initiation |
Substance use initiation for each substance will be assessed with three items from the Drug Use Questionnaire. The items will be asked for each substance at baseline and each follow up timepoint, and are used to calculate time of initiation and incidence. Child responds Yes/No to the "ever used" question and if responds yes, provides day of first use. Frequency of use question has responses: (0) Never, (1) Once a month or less, (2) About once a week, (3) Several times a week, (4) About once a day, (5) Several times a day. |
