The goal of this 2-arm randomized control trial is to determine the impact of a community health worker delivered coaching intervention, GRIT, on preventing the early initiation of regular use of alcohol and cannabis among adversity-impacted adolescents ages 11-14 who do not regularly use alcohol or cannabis at baseline. The specific aims include: * Aim 1. Examine the effect of GRIT on preventing the early initiation of regular alcohol and cannabis use over time. * Aim 2. Examine the role of youth and caregiver self-regulation in mediating the effect of GRIT on adolescent rates of alcohol and cannabis use. Researchers will compare participants who are randomized to the GRIT intervention to an active control group, receiving a Digital Citizenship Curriculum, to see if those who participate in GRIT experience greater improvements in self-regulation and lower cardiometabolic risks. Participants will: * Be randomized to either receive the GRIT intervention (experimental group) or the Digital Citizenship Curriculum (active control group) * Complete 3 in-person visits at baseline, post-intervention, and 12-month post intervention * Complete HRV assessments using emWave Pro Plus and survey assessments on REDCap during in-person visits. * Participate in six 60-minute sessions conducted over 8 weeks via Zoom with an assigned community-health worker * Be invited to complete a booster session at 6-months post-intervention * Complete online measures at baseline, post-intervention, 6-month, and 12-month post-intervention
Adverse Childhood Experiences (ACEs) constitute a serious public health issue, impacting almost half of adolescents and over 60% of adults in the United States. High ACEs exposure (i.e., four or more ACEs) may result in self-dysregulation (i.e., challenges managing cognitions, emotions, and behaviors) and lead to early initiation of alcohol and substance use (e.g., self-medication hypothesis) and other biopsychosocial responses, such as cardiometabolic risks (e.g., lowered heart rate variability \[HRV\], increased weight and blood pressure, and sleep disturbance), and emotional and/or cognitive dysregulation. Health inequities resulting from self-dysregulation are highest among minoritized and impoverished populations, who experience disproportionately higher exposure to ACEs, and early adolescence is a time in which experimentation with alcohol and drugs occurs. Although not all adolescents who experiment with drugs are later diagnosed with a substance use disorder, those who engage early (i.e., before the age of 14) and regularly are at greater risk. Youth with four or more ACEs may experience a unique type of adversity characterized by chronic, unpredictable stress shaping their perception of and responses to stress. However certain strategies, called Shift and Persist, can mitigate these exposures where one shifts their attention from adverse experiences to future-directed behaviors (e.g., healthy habit adoption, stress management), resulting in improved self-regulation and lower cardiometabolic risks. GRIT is a community health worker (CHW)-delivered psychoeducational health coaching intervention that promotes coping with high exposure to ACEs to regulate the stress response using self-regulation techniques and the development of healthy habits recommended by the California Surgeon General (e.g., supportive relationships, quality sleep, physical activity). We propose conducting a 2-arm Randomized Controlled Trial (RCT) (GRIT vs an active control \[i.e., digital citizenship\]) with 210 adolescent-caregiver dyads to determine GRIT's impact on preventing the early initiation of regular use of alcohol and cannabis among adversity-impacted adolescents ages 11-14 who do not regularly use alcohol or cannabis at baseline. The specific aims will: Aim 1. Examine the effect of GRIT on preventing the early initiation of regular alcohol and cannabis use over time. H1: Adolescents enrolled in GRIT will have lower rates of regular alcohol and/or cannabis use at post-intervention, 6-, and 12-month follow-ups compared to adolescents in the active control group. Aim 2. Examine the role of youth and caregiver self-regulation in mediating the effect of GRIT on adolescent rates of alcohol and cannabis use. H2: Youth and caregiver self-regulation will mediate youth initiation of regular alcohol and cannabis use. This community-based study seeks to establish efficacy for a brief, accessible secondary prevention program. Once efficacy is established and the mechanism of action is identified, larger confirmatory efficacy studies and effectiveness trials using innovative approaches (i.e. multi-family groups and social media) in additional settings offer the opportunity to scale and decrease the research-to-practice gap for adversity-impacted youth.

RECRUITINGAlcohol, Cannabis & Other Substance Use: CDC Youth Risk Behavior Surveillance System (YRBSS)+ Timeline Followback Method Assessment (TFB)
The YRBSS is a multiple-choice survey that collects health behavior history, including questions about alcohol and cannabis use. Youth who report any substance use in the last 30 days on the YRBS will complete the Timeline Followback Method Assessment (TFB) for the last 30 days. The TFB is used to assess recent marijuana, cigarette, alcohol and other drug use. The 14-item self-administered TFB asks respondents to retrospectively estimate their daily drug over a designated period of time, from 7 days to 2 years prior to the administration date. The TFB can be used to obtain a variety of quantitative estimates of substance use, including change in substance use. Predictive validity, concordance of the TFB with other measures of drug use and strong convergence among the TFB, urine assays, self-report and collateral parent and sibling reports have been demonstrated among white and minoritized adolescents.

Emotional Regulation: Difficulties in Emotional Regulation- Short Form (DERS-SF)
The DERS-SF is an 18-item abbreviated version of the original, 36-item DERS questionnaire. It measures emotion regulation ability based on 6 subscales: strategies, non-acceptance, impulse, goals, awareness, and clarity. All subscales on the DERS-SF are highly correlated with the original DERS, with correlations ranging from .91 -.98. Each of the DERS-SF subscales have a Cronbach α\> .70 (ranging from .79 to .91). Total scores range from 18 to 90, with higher total score on the DERS-SF indicating greater difficulties in emotion regulation.
