The United States is experiencing a shift in the cultural composition of its' population, specifically seen in the increase of immigrants and children of immigrants. These populations encounter unique stressors that influence the prevalence rates of adverse mental health outcomes such as depressive symptomatology. However, little has been done to develop culturally sensitive preventative programming in order to provide tier one support to these populations. This study sought to evaluate the perceived effectiveness and acceptability of a tier one psychoeducational preventative session geared for immigrant parents to increase their knowledge of healthy parent-adolescent communication. Results of the study indicated that immigrant parents (N= 86) found the psychoeducational session to be both effective and acceptable. Furthermore, certain characteristics of these immigrant parents led to differences in the perceived effectiveness and acceptability, such as the existing quality of parent-adolescent relationships and parent demographics. Study findings demonstrate the importance of increasing efforts to provide culturally-sensitive brief preventative programming for tier one immigrant populations. Implications for mental health professionals serving immigrant parent populations indicate the need for greater research into population characteristics as they influence the success of culturally-sensitive mental health programming as well a need to better evaluate long term outcomes of mental health programming.
