Health Literacy Strategies — Apply strategies to enhance health literacy and informed decision-making

The concept of health literacy first gained formal attention in the 1970s when healthcare researchers began recognizing that a significant proportion of patients could not adequately understand the written and verbal information they received from clinicians. Early studies revealed that medical jargon, complex discharge instructions, and dense informed-consent documents created barriers to treatment adherence and self-management. For occupational therapy practitioners, this recognition was particularly significant because effective intervention planning depends on the client's ability to comprehend goals, follow home exercise programs, and make informed choices about their own care trajectories. As the profession evolved its client-centered models throughout the late twentieth century, health literacy emerged as a critical variable in the analysis, interpretation, and planning process—one that directly affects occupational performance outcomes.

This historical trajectory reveals a fundamental shift: health literacy is no longer viewed solely as a deficit in the individual but rather as a shared responsibility between healthcare systems and the populations they serve. For OT practitioners preparing for the NBCOT examination, the critical question becomes—how do we systematically assess a client's health literacy level during the evaluation phase and then integrate evidence-based communication strategies into the intervention planning process to ensure that clients can meaningfully participate in their own recovery and occupational engagement?

Understanding health literacy within the occupational therapy context requires grasping several foundational principles that connect literacy assessment to intervention planning. The Occupational Therapy Practice Framework (OTPF-4) emphasizes that client factors—including cognitive abilities, communication skills, and educational background—directly influence how clients engage with therapeutic recommendations. Health literacy, therefore, is not a peripheral concern but a core component of occupational profiling and activity analysis. The following principles anchor health literacy strategies within Domain 2 competencies.

This cycle is not a linear checklist but a dynamic, iterative process that mirrors the broader OT clinical reasoning model. When a client demonstrates incomplete understanding during the teach-back phase, the practitioner does not simply repeat the same instructions more slowly. Instead, the practitioner returns to stage two and fundamentally restructures how information is presented—perhaps replacing a written handout with a pictorial guide, switching from verbal instructions to a physical demonstration, or engaging a family member as a co-learner. The critical insight for NBCOT preparation is that health literacy strategies are embedded within every domain of OT practice, from initial evaluation through discharge planning, and they must be documented as part of the clinical reasoning process.

Screening Tools for Health Literacy

Before an OT practitioner can select appropriate communication strategies, a baseline understanding of the client's health literacy must be established. Several validated screening instruments exist, each with different strengths and administration requirements. The Rapid Estimate of Adult Literacy in Medicine (REALM) is a word-recognition test that takes approximately two to three minutes to administer, making it practical in fast-paced clinical settings. The Test of Functional Health Literacy in Adults (TOFHLA) assesses both reading comprehension and numeracy, providing a more nuanced picture but requiring approximately 22 minutes for the full version. The Newest Vital Sign (NVS) uses a nutrition label to test reading and computational skills in roughly three minutes. For OT-specific practice, practitioners may also employ informal screening techniques such as observing whether clients can read appointment reminders, follow written home exercise programs, or correctly identify their medications.

The Teach-Back Method: Step-by-Step Mechanism

The teach-back method is perhaps the single most evidence-supported strategy for verifying client comprehension in healthcare settings. The mechanism operates on the principle that if a learner cannot explain a concept in their own words, they have not genuinely internalized it. In OT practice, the method proceeds through a structured sequence. First, the practitioner presents one concept at a time—for instance, a single precaution following a total hip replacement, such as avoiding hip flexion beyond 90 degrees. Second, the practitioner uses plain language and a physical demonstration. Third, the practitioner asks the client to demonstrate or verbally restate the concept using a non-shaming prompt such as, 'I want to make sure I explained that clearly—can you tell me in your own words what we just discussed?' Fourth, the practitioner listens for accuracy and completeness. Fifth, if the client's response reveals misunderstanding, the practitioner re-teaches using a different modality and then repeats the teach-back. Research indicates that using teach-back consistently reduces 30-day hospital readmission rates and improves adherence to home programs.

Health literacy strategies in occupational therapy can be organized into three overlapping domains: verbal communication strategies, written and visual material design, and environmental and systems-level modifications. Each domain contains specific, actionable techniques that OT practitioners can integrate into their daily practice. The following diagram classifies these strategies by domain and provides examples of each.

Readability Assessment: Quantifying Written Material Complexity

While not a mathematical discipline per se, health literacy does employ quantitative tools for evaluating the readability of client education materials. The Flesch-Kincaid Grade Level formula is the most commonly referenced readability metric in healthcare settings. It calculates the approximate U.S. school grade level required to understand a passage based on sentence length and syllable count.

OT practitioners should routinely apply readability assessments to their own handouts, home exercise programs, and discharge instructions. Most word processing software includes built-in readability statistics, and free online tools such as the Hemingway Editor can identify sentences that are too complex. The goal is not to oversimplify clinical content but rather to present it in a way that maximizes client comprehension and empowers informed decision-making about care.

The following scenario demonstrates how an OT practitioner integrates health literacy strategies into the clinical reasoning process during intervention planning for a client with low health literacy.

No single health literacy strategy is sufficient in isolation; each has distinct strengths and limitations that practitioners must weigh when planning interventions. Understanding these trade-offs is essential for NBCOT preparation, where exam items frequently require selecting the most appropriate strategy for a given clinical context. The following table compares the major strategies across practical dimensions relevant to OT practice.

Health literacy strategies do not exist in a vacuum; they connect to broader theoretical frameworks that guide advanced OT practice and research. Understanding these connections positions the entry-level practitioner to engage with emerging evidence and evolving practice standards. The Healthy People 2030 framework's distinction between personal health literacy and organizational health literacy represents a paradigm shift that has direct implications for how OT departments structure their education programs, design their physical environments, and train their staff.

Looking forward, the integration of digital health literacy into OT practice is rapidly expanding. As telehealth and mobile health applications become standard delivery models, practitioners must assess not only traditional print literacy but also the client's ability to navigate patient portals, use wearable devices, and critically evaluate health information found online. The NBCOT exam increasingly reflects these trends, and candidates should be prepared to address scenarios involving technology-mediated health education, where health literacy barriers may manifest differently than in face-to-face encounters—for example, a client who is a fluent reader but cannot navigate a medication management app due to low digital literacy.
