On September 20, 2017, Hurricane Maria made landfall in Puerto Rico, devastating the archipelago and forcing thousands of Puerto Ricans to migrate to the U.S. mainland. Guided by a cultural stress theory framework, the present mixed method study examined how various cultural stressors impact participants' daily interactions and mental health outcomes. A total of 319 adult Hurricane Maria survivors residing on the U.S. mainland participated in the study. A mixed method sequential explanatory design was used. First, we used latent profile analysis (LPA) and multinomial logistic regression to identify the varied cultural stress experiences that participants had. Then we used data from semistructured interviews to better understand the experiences of participants classified into the different LPA profiles. Four profiles were identified: "moderate cultural stress" (35%), "overall low" (29%), "high cultural stress" (26%), and "low language stress" (10%). Multinomial regression indicated that members of the moderate cultural stress, high cultural stress, and low language stress profiles all reported significantly higher depressive and anxiety symptoms compared to members of the overall low profile. Qualitative data exemplified the daily experiences of participants placed into each profile, demonstrating that participants have rich and varied experiences that can contribute to their mental health symptoms. The present study documents the contributions of hurricane trauma and cultural stress vis-à-vis current mental health symptoms. Clinicians working with Hurricane Maria survivors should be cognizant of and inquire about migration-related cultural stressors including discrimination, feelings of being unwelcomed, and difficulty communicating in the destination community's dominant language.
