This qualitative critical ethnographic study aimed to investigate the role of health literacy access among adult Hispanic Americans and how it affects self-care attitudes. The goal of this qualitative critical ethnographic study design was to see if previous healthcare service experiences influenced Hispanic American adults' attitudes toward obtaining personal healthcare services, health literacy, and self-care services (Creswell & Poth, 2018; Fetterman, 2020). According to Creswell and Poth (2018), in this qualitative study, the critical ethnographic research technique was used to describe and assess the shared and learned patterns of values, actions, beliefs, and language in a culture-sharing group. This strategy reacts to today's culture, in which power, prestige, privilege, and authority help marginalized people of all classes, ethnicities, and genders. The study's findings support the idea that adult Hispanic Americans' healthcare experiences influence their views regarding self-care. Other study findings include the significance of opposing viewpoints and the concept of self-care based on access to health literature and doctor's appointments. The findings also stressed the significance of obtaining health literacy through internet access, the cost of insurance, doctor visit experiences, and the significance of quality of care for self-care. The intention of this study is to gain a better understanding of the function of health literacy access among adult Hispanic Americans and how it influences self-care attitudes (Fetterman, 2020).
