A Family-Based Alcohol Preventive Intervention for Latino Emerging Adults

Emerging Adult Self-Efficacy

The Latino Emerging Adult (LEA) Self-Efficacy scale was designed to appraise Latino emerging adults' healthy identity formation and healthy behaviors. Participating emerging adults self-administered this online assessment twice during the study--at baseline, pre-intervention, and 3-4 months post-intervention. The scale includes 14 items (e.g., I feel confident that I can successfully tackle the challenges of becoming an adult; I draw on strengths from my family's cultural background to help me deal with the stress of becoming an adult; I use healthy activities to deal with stress; Mentors \[parents or other trusted adults\] are important in the life success of emerging adults). Answer choices include: 1-Strongly disagree; 2-Disagree; 3-Agree; 4-Strongly Agree. Higher scores indicate higher emerging adult self-efficacy. The Cronbach's alpha was .78. (Citation: Center for Equity Promotion. \[2019\]. Latino Emerging Adult Self-Efficacy scale. University of Oregon.)

Time frame: 3-4 months

Parent-Emerging Adult Relationship Quality

The Latino Emerging Adult (LEA) Parent-Emerging Adult Relationship Quality scale was designed by the research team. Participating emerging adults self-administered this online computer-based survey twice during the study--at baseline and approximately 3-4 months later, after the completion of the intervention program. The scale includes 6 items (e.g., Even though my parent can be annoying, I know that she/he is my best supporter; Even when I think that my parent is wrong, I understand where she/he is coming from). Answer choices include: 0-Not at all true; 1-Not really true; 2-Somewhat true; 3-Very true. Higher scores equal higher quality relationships as reported by emerging adults. The Cronbach's alpha was .82. (Citation: Center for Equity Promotion. \[2019\]. Latino Emerging Adult Parent-Emerging Adult Relationship Quality scale. University of Oregon.)

Time frame: 3-4 months

Parent Trust in Emerging Adult Decision-Making

The Latino Emerging Adult (LEA) Parent Trust in Emerging Adult Decision-Making scale was designed by the research team. Participating parents self-administered this online computer-based survey twice during the study--at baseline and approximately 3-4 months later, after the completion of the intervention program. The scale includes 6 items (e.g., I am confident that my emerging adult child will make the right choices in life; I'm afraid that my emerging adult child will not be able to figure out what to do in life; My emerging adult child knows what to do when s/he needs to make an important life decision). Answer choices include: 0-Not at all true; 1-Not really true; 2-Somewhat true; 3-Very true. Higher scores indicate higher parent-reported trust in emerging adult children's decision-making. The Cronbach's alpha was .77. (Citation: Center for Equity Promotion. \[2019\]. Latino Emerging Adult (LEA) Parent Trust in Emerging Adult Decision-Making scale. University of Oregon.)

Time frame: 3-4 months

Parent support

The Latino Emerging Adult (LEA) Parent Support scale was designed by the research team. Participating parents self-administered this online computer-based survey twice during the study--at baseline and approximately 3-4 months later, after the completion of the intervention program. The scale includes 8 items (e.g., Even if \[child's name\] doesn't listen to me one time, I still know that I can get through to him/her the next time; \[child's name\] comes to me and talks to me about important issues in his/her life; I generally know how to connect with or reach out to \[child's name\] when they need my support). Answer choices include: 1-Strongly disagree; 2-Disagree; 3-Agree; 4-Strongly Agree. Higher scores indicate higher parent support. The Cronbach's alpha was .82. (Citation: Center for Equity Promotion. \[2019\]. Latino Emerging Adult (LEA) Parent Support scale. University of Oregon.)

Time frame: 3-4 months

Emerging adult alcohol consumption

Three items from the University of Michigan's Monitoring the Future survey were used to appraise alcohol use (Johnston, L. D., O'Malley, P. M., Bachman, J. G., Schulenberg, J. E., \& Miech, R. A. (2015). Monitoring the Future national survey results on drug use, 1975-2014: Volume II, college students and adults ages 19-55.). Items include: 1. Have ever tried even a few sips of alcohol? Yes No (if no, skip to #3) 2. If YES: How old were you when you first tried at least a few sips of alcohol? \_\_\_\_\_ years old 3. During the last 3 months, what was the HIGHEST number of drinks that you drank in a single day?

Time frame: 3-4 months

Drinking-related risk behaviors

Twelve items from the Monitoring the Future survey were used (Johnston, L. D., O'Malley, P. M., Bachman, J. G., Schulenberg, J. E., \& Miech, R. A. (2015). Monitoring the Future national survey results on drug use, 1975-2014: Volume II, college students and adults ages 19-55). Exemplar items include: During the last 3 months, about how many days did you drink until it affected your ability to make decisions?; How many times in the last 3 months did you use other drugs after you had been drinking?; and, In the past 3 months, how many times did you ride in a car when you knew the driver was drunk or high?

Time frame: 3-4 months

Drinking-related harm reduction behaviors

The Latino Emerging Adult (LEA) Drinking-related Harm Reduction Behaviors scale was designed by the research team. Participating emerging adults self-administered this online survey twice during the study--at baseline and approximately 3-4 months later, after the completion of the intervention program. The scale includes 13 items (e.g., If one of my friends is really drunk, I make sure that person is safe; If I have been drinking too much I feel comfortable finding a ride home with a sober driver or finding a place to sleep; In my group of friends, if someone has been drinking too much we make sure that he/she doesn't drive). Answer choices include: 1-Strongly disagree; 2-Disagree; 3-Agree; 4-Strongly Agree. Higher scores indicate EAs practice more alcohol-related harm-reducing behaviors. The Cronbach's alpha was .93. (Citation: Center for Equity Promotion. \[2019\]. Latino Emerging Adult (LEA) Drinking-related Harm Reduction Behaviors scale. University of Oregon.)

Time frame: 3-4 months

Emerging adult perceived stress

Emerging adult participants respond in an online survey to the 10-item Perceived Stress Scale (PSS-10; Cohen, S. and Williamson, G. \[1988\]. Perceived stress in a probability sample of the United States. In S. Spacapan \& S. Oskamp \[Eds.\] The social psychology of health \[pp. 31-67\]. Sage Publications, Inc.). Answer choices range from Never = 0 to Very often = 4. Responses are summed with higher sum scores reflecting higher perceived stress. The Cronbach's alpha for emerging adults in this study was .82.

Time frame: 3-4 months

Parent perceived stress

Parent participants respond in an online survey to the 10-item Perceived Stress Scale (PSS-10; Cohen, S. and Williamson, G. \[1988\]. Perceived stress in a probability sample of the United States. In S. Spacapan \& S. Oskamp \[Eds.\] The social psychology of health \[pp. 31-67\]. Sage Publications, Inc.). Answer choices range from Never = 0 to Very often = 4. Responses are summed with higher sum scores reflecting higher perceived stress.

Time frame: 3-4 months

Bicultural identity integration

Sixteen items from the Bicultural Identity Integration Scale (BIIS-2) were used to capture variation in emerging adults' experiences of acculturation. (Huynh, Q. L., Benet-Martínez, V., \& Nguyen, A. M. D. \[2018\]. Measuring variations in bicultural identity across US ethnic and generational groups: Development and validation of the Bicultural Identity Integration Scale-Version 2 \[BIIS-2\]. Psychological Assessment, 30\[12\], 1581.). Exemplar items include: I feel part of a combined culture that is a mixture of Hispanic/Latino and American; I find it difficult to combine Hispanic/Latino and American cultures; I do not blend my Hispanic/Latino and American cultures. Answer choices range from 1 (strongly disagree) to 5 (Strongly agree). The scale taps cultural blendedness versus compartmentalization and cultural harmony versus conflict, and final scores are averages.

Time frame: 3-4 months

Emerging adult future orientation

Ten items from the Steinberg et al. Future Orientation Scale were used (Steinberg L, Graham S, O'Brien L, Woolard J, Cauffman E, Banich M. \[2009\]. Age differences in future orientation and delay discounting. Child Development. Jan-Feb;80\[1\]:28-44.) The 10 items include question numbers 2, 3, 4, 5, 7, 9, 10, 12, 13, 15 across 4 sub-scales including Planning Ahead, Time Perspective, Anticipation of Future Consequences, and Anticipation of Future Consequences. All items are scored left to right on a scale of 1-4. Reverse score items 1, 3, 4, 6, 8, 11, and 14, so that higher scores indicate a stronger future orientation.

Time frame: 3-4 months

Parent hope for emerging adult child's future

This 12 item scale appraises parents' hopes for their emerging adult children's future. Answer options range from 0-Not at all true to 3-Very true.
