| Primary | Change From Baseline in Parent Report of Parent-child Communication Quality at Week 4 | Parent-child communication quality will be adapted from the 16-item Parent-Adolescent Communication Scale (PACS; Barnes & Olson, 1985; Prado et al., 2007; α = .85). Participants are asked to indicate on a 4-point scale (1=strongly disagree; 2=disagree; 3=agree; 4=strongly agree) the extent to which they agree with a series of 16 statements (e.g., I can discuss my beliefs with my child without feeling embarrassed). Higher scores indicate a better outcome. Responses on the items were averaged together. | If a participant was missing data for any independent or dependent variables, they were not included in the outcome analyses. | Posted | | Least Squares Mean | Standard Error | score on a scale | | Baseline and Week 4 | | | | ID | Title | Description |

| Primary | Change From Baseline in Child Substance Use Intentions at Week 4 | Substance use intentions will be assessed by asking "During the next year, do you think you will drink alcohol" (4-point scale; 1=I definitely will not; 2=I probably will not; 3=I probably will; 4=I definitely will; higher scores indicate a worse outcome). Questions will also be asked for use of tobacco, vape, marijuana, and prescription drugs without a prescription, for a total of 5 questions. Responses were averaged together and then dichotomized. Any participant with a mean of one ("I definitely will not") was rescored as "0" (no intentions) and any participant with a mean greater than one was rescored as "1" (any intentions). A rescored value of "1" indicated a worse outcome. Outcome measure type ("number") indicates the percentage of people who had a rescored value of "1" ("any intentions"). | Analyses were conducted using observed data instead of imputed. | Posted | | Number | | percentage of participants with "1" | | Baseline and Week 4 | | | | ID | Title | Description |
