As of 2017, the number of international immigrants worldwide increased from 220 million to 248 million, and will continue to rise [16]. Growing diversity worldwide requires a stronger emphasis on multicultural competency among mental health professionals. Learning multicultural competency skills is a career-long commitment that begins in practicum training and is modeled and reinforced through supervision. The Multicultural Developmental Supervisory Model (MDSM) is an evidence-based model that focuses on supervisory dyads and multicultural competence [12]. Using the MDSM [12] as a guide reflective of our training, four graduate supervisees share their supervision experiences in learning to conduct clinical interviews in Spanish with undocumented Latinx immigrant minors in government custody in the United States, a rising population with unique clinical considerations. Our supervisor includes her experience in training and fortifying beginning mental health professionals’ skills in conducting these evaluations. In this contribution, we illustrate our trajectory from different training developmental stages, including the process of conceptualizing clinical cases, and transitioning languages in conducting clinical interviews, as well as considering our own cultural identities in clinical work. While our experience focuses on bicultural and bilingual training in the U.S., this aspect of clinical training is growing increasingly relevant around the world, especially in Europe where 54% of tчёёhe population is multilingual [10]. Although we used the MDSM model as a helpful framework in guiding our multicultural development, empirical research is needed to examine the utility of this model.

Background: Electronic delivery systems (e.g., vapes, e-cigarettes) are now popular modes of cannabis and nicotine administration that are often used by the same individuals; however, we still know little about dual nicotine and cannabis vaping. Materials & Methods: An online convenience sample of adult nicotine and/or cannabis vape users residing in the United States completed a 60 min survey on sociodemographic characteristics, cannabis and/or nicotine vape use behaviors and dependence, reasons for vape use, and perceptions of benefits and harms. After data cleaning, we compared dual vs. nicotine-only and cannabis-only vape users with univariate statistics and step-wise hierarchical linear regression analyses. Additionally, we assessed the factor structure, internal consistency, and criterion and convergent validity of the Penn State Cannabis Vaping Dependence Index (PSCVDI). Results: The final sample included 357 dual, 40 cannabis, and 106 nicotine vape users. Compared to nicotine- and cannabis-only vapers, dual vapers started using their nicotine and cannabis vapes at a younger age (p < 0.001), used them for more years (p < 0.001), and were less likely to use their nicotine vape to replace combustible cigarettes (p = 0.047). Dual users vs. single-substance users did not have significantly higher nicotine or cannabis vape dependence scores after controlling for sociodemographic and use behaviors. The PSCVDI showed adequate validity for measuring cannabis vape dependence. Conclusions: This survey is the first to highlight important differences in vape use behaviors and reasons for use between dual vs. cannabis- and nicotine-only vape users.
