I am the Bilingual project coordinator for the SADE Study, looking at the impact of a sensory adapted dental environment on enhancing the oral care experience of children with autism during dental cleanings.
I am a PhD candidate and USC Center for Health Equity in the Americas Fellow whose work merges the worlds of occupation, culture, and public health. My dissertation, Exploring the role of culture related to in-home oral care routines in Latino families, uses a mixed-methods approach to first identify health disparities in oral care for children in Latino families with and without autism spectrum disorder (ASD), and then create a culturally appropriate tool (survey) to give to Latino parents. In phase one, by employing qualitative research methods like narrative interviewing and photovoice to interview 16 families (8 with typically developing children and 8 with children with ASD), I will critically examine the interplay between person and context, and identify how unique aspects of Latino culture and/or ASD diagnosis may influence oral health related occupations. In phase two, I will take the results from the qualitative data to tailor an oral health knowledge, attitudes, and behavior survey to be more culturally relevant to administer to Latino parents.
A Los Angeleno, I identify as a member of the local Latino community, and am passionate about research that explores the role of Latino culture in influencing health behaviors, as well as communicating culturally pertinent health information. Researching the in-home oral health activities of Latino children will expand the understanding of daily occupations in this at-risk population, and help to develop future targeted prevention and intervention programs, ultimately contributing to closing gaps in care and achieving health equity in the field of oral health.

Reorganized, expanded, and updated, this new edition of the award-winning Lifestyle Redesign gives practical guidance in this preventative occupational therapy program for independent-living older adults. The work integrates the concept of the USC's landmark Well Elderly Studies, which determined that preventive occupational therapy greatly enhances the health and quality of life of independent-living older adults.
Twelve modules, including those on longevity, stress, home safety and navigating health care, illustrate how to incorporate the program into practice. Includes a flash drive with program handouts.

An occupational perspective is relevant in examining how the unique context of a person’s life and environment can impact the types of occupations in which he or she participates, and the dilemmas that can occur when restrictive surroundings or perceived lack of lifestyle options constrain occupational choices. This paper examines how participation in gangs by Latino adolescent males may be due to the limited options for other occupations that low socioeconomic status (SES) neighborhoods afford. By presenting narrative from the memoir of a former gang member, alongside county public health records, the engaging and health-promoting occupations as well as health-threatening occupations of gang life are explored. This scholarly discussion contributes to occupational science by evaluating the relationship between context and occupational possibilities for Latino male adolescents living in constrained environments.

Journal of Spinal Cord Medicine. Advance online publication. https://doi.org/10.1080/10790268.2017.1313931 Show abstract
Context/Objective. Medically serious pressure injuries (MSPrIs), a common complication of spinal cord injury (SCI), have devastating consequences on health and well-being and are extremely expensive to treat. We aimed to test the efficacy of a lifestyle-based intervention designed to reduce incidence of MSPrIs in adults with SCI.
Design. A randomized controlled trial (RCT), and a separate study wing involving a nonrandomized standard care control group.
Setting. Rancho Los Amigos National Rehabilitation Center, a large facility serving ethnically diverse, low income residents of Los Angeles County.
Participants. Adults with SCI, with history of one or more MSPrIs over the past 5 years: N=166 for RCT component, N=66 in nonrandomized control group.
Interventions. The Pressure Ulcer Prevention Program, a 12-month lifestyle-based treatment administered by healthcare professionals, largely via in-home visits and phone contacts.
Outcome Measures. Blinded assessments of annualized MSPrI incidence rates at 12 and 24 months, based on: skin checks, quarterly phone interviews with participants, and review of medical charts and billing records. Secondary outcomes included number of surgeries and various quality-of-life measures.
Results. Annualized MSPrI rates did not differ significantly between study groups. At 12 months, rates were .56 for intervention recipients, .48 for randomized controls, and .65 for nonrandomized controls. At follow-up, rates were .44 and .39 respectively for randomized intervention and control participants.
Conclusions. Evidence for intervention efficacy was inconclusive. The intractable nature of MSPrI threat in high-risk SCI populations, and lack of statistical power, may have contributed to this inability to detect an effect.
Trial Registration. ClinicalTrials.gov NCT01999816.

Background. Randomized trials of complex, non-pharmacologic interventions implemented in home and community settings, such as the University of Southern California (USC)-Rancho Los Amigos National Rehabilitation Center (RLANRC) Pressure Ulcer Prevention Study (PUPS), present unique challenges with respect to (1) participant recruitment and retention, (2) intervention delivery and fidelity, (3) randomization and assessment, and (4) potential inadvertent treatment effects.
Purpose. We describe the methods employed to address the challenges confronted in implementing PUPS. In this randomized controlled trial, we are assessing the efficacy of a complex, preventive intervention in reducing the incidence of, and costs associated with, the development of medically serious pressure ulcers in people with spinal cord injury.
Methods. Individuals with spinal cord injury recruited from RLANRC were assigned to either a 12-month preventive intervention group or a standard care control group. The primary outcome is the incidence of serious pressure ulcers with secondary endpoints including ulcer-related surgeries, medical treatment costs, and quality of life. These outcomes are assessed at 12 and 24 months after randomization. Additionally, we are studying the mediating mechanisms that account for intervention outcomes.
Results. PUPS has been successfully implemented, including recruitment of the target sample size of 170 participants, assurance of the integrity of intervention protocol delivery with an average 90% treatment adherence rate, and enactment of the assessment plan. However, implementation has been replete with challenges. To meet recruitment goals, we instituted a five-pronged approach customized for an underserved, ethnically diverse population. In intervention delivery, we increased staff time to overcome economic and cultural barriers to retention and adherence. To ensure treatment fidelity and replicability, we monitored intervention protocol delivery in accordance with a rigorous plan. Finally, we have overcome unanticipated assessment and design concerns related to (1) determining pressure ulcer incidence/severity, (2) randomization imbalance, and (3) inadvertent potential control group contamination.
Limitations. We have addressed the most daunting challenges encountered in the recruitment, assessment, and intervention phases of PUPS. Some challenges and solutions may not apply to trials conducted in other settings.
Conclusions. Overcoming challenges has required a multifaceted approach incorporating individualization, flexibility, and persistence, as well as the ability to implement needed mid-course corrections.

Conducting intervention research among underserved populations: Lessons learned and recommendations for researchers.

Randomized controlled trials (RCTs) are considered the criterion standard in research design for establishing treatment efficacy. However, the rigorous and highly controlled conditions of RCTs can be difficult to attain when conducting research among individuals living with a confluence of disability, low socioeconomic status, and being a member of a racial/ethnic minority group, who may be more likely to have unstable life circumstances. Research on effective interventions for these groups is urgently needed, because evidence regarding approaches to reduce health disparities and improve health outcomes is lacking. In this methodologic article, we discuss the challenges and lessons learned in implementing the Lifestyle Redesign for Pressure Ulcer Prevention in Spinal Cord Injury study among a highly disadvantaged population. These issues are discussed in terms of strategies to enhance recruitment, retention, and intervention relevance to the target population. Recommendations for researchers seeking to conduct RCTs among socioeconomically disadvantaged, ethnically diverse populations are provided.
