A multisite cross-sectional study of intercultural competencies in doctor of physical therapy students

BACKGROUND: Physical therapists (PTs) work in diverse communities with individuals whose identities and beliefs may differ significantly from their own. Academic institutions must include intentional curriculum aimed at graduating PTs who can skillfully navigate intercultural encounters. Being prepared to engage with difference and demonstrate skills related to intercultural competencies (ICC) will prepare entry-level PTs to provide individualized, high-quality care. Intercultural competencies are essential skills that can reduce healthcare disparities, and promote equitable and inclusive healthcare delivery. This study examined the impact of PT curricula, student demographics, and participation in intercultural learning experiences (ILEs) on students’ development of ICC. METHODS: A cross-sectional study of 8 Doctor of Physical Therapy (DPT) programs in the United States (US) compared ICC in first-year (F) and third-year students (T), and T who participated in an ILE (T + ILE) to those who did not (T-only). Subjects included 1,038 students. Outcome measures included The Inventory for Assessing the Process of Cultural Competence-among healthcare professionals-Student Version(©) (IAPCC-SV), and a demographic survey. RESULTS: Independent t-tests showed that group T (mean = 64.34 ± 5.95, 95% CI: 63.78-64.90) had significantly higher IAPCC-SV total scores than group F (mean = 60.8 ± 5.54, 95% CI = 60.33-61.27, p < 0.05). Group T + ILE (mean = 65.81 ± 5.71, 95% CI = 64.91-66.71) demonstrated significantly higher IAPCC-SV total scores than group T-only (mean = 63.35 ± 5.8, 95% CI = 62.6-64.1, p = 0.039). A one-way ANOVA and post hoc comparisons showed that the 25 to 34-year age group (mean = 63.80 ± 6.04, 95% CI = 63.25-64.35, p < 0.001) and the ≥ 35-year age group (mean = 64.21 ± 5.88, 95% CI = 62.20-66.22, p < .024) had significantly higher IAPCC-SV total scores, than the 18 to 24-year age group (mean = 60.60 ± 5.41, 95% CI = 60.09-61.11). Students who identified in US census minority ethnic or racial categories (US-Mn) (mean = 63.55 ± 5.78, 95% CI = 62.75-64.35) had significantly higher IAPCC-SV total scores than students who identified in US majority ethnic or racial categories (US-Mj) (mean = 61.98 ± 5.97, 95% CI = 61.55-62.413, p = .0001). CONCLUSIONS: Results of the study support the hypothesis that DPT programs can promote the development of intercultural skills in students. The ultimate objective of this academic preparation is to improve the student’s ability to deliver equitable, person-centered healthcare upon entry into practice. Specific ICC for entry-level DPT students are not clearly defined by US physical therapy professional organizations, academic institutions, or accrediting body. Students who participated in an ILE exhibited higher levels of ICC when compared to those who did not. Findings from this study can guide curriculum development, utilization of resources, and outcomes assessment. More research is needed to examine characteristics of an ILE that could inform best practice.
