Impact of Sign-Language Awareness Training on Communication Skills among Healthcare Students in Nigeria

Abstract

Effective communication is an essential component of quality healthcare, and healthcare students require appropriate communication skills to interact effectively with patients from diverse backgrounds and with different communication needs. Deaf and hard-of-hearing individuals may experience barriers when accessing healthcare services because of communication difficulties, limited availability of interpreters, healthcare providers' inadequate knowledge of sign language, and misconceptions regarding deafness. Healthcare students who have limited awareness of sign language may experience difficulty communicating with patients who use sign language, potentially affecting history-taking, health education, informed consent, patient understanding, and the overall quality of care. Sign-language awareness training provides an opportunity to improve students' understanding of deaf culture and basic sign-language communication and to develop more inclusive healthcare communication skills. Against this background, this study investigates the impact of sign-language awareness training on communication skills among healthcare students in Nigeria. The study will be anchored on the Social Model of Disability, Social Cognitive Theory, and Health Literacy Theory. The Social Model of Disability emphasizes that communication barriers experienced by deaf and hard-of-hearing individuals may be intensified by inaccessible healthcare environments and inadequate communication support rather than by hearing impairment alone. Social Cognitive Theory explains how observation, demonstration, behavioural modelling, practice, feedback, self-efficacy, and reinforcement may influence healthcare students' development of sign-language and inclusive communication skills. Health Literacy Theory emphasizes the importance of effective communication in enabling patients to obtain, understand, and use health information and participate meaningfully in healthcare decisions. Collectively, these theoretical perspectives provide a suitable framework for explaining how sign-language awareness training may influence communication skills among healthcare students in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise undergraduate and postgraduate healthcare students aged 18 years and above enrolled in selected universities and healthcare training institutions across Nigeria. Participants may include students of medicine, nursing, pharmacy, physiotherapy, medical laboratory science, radiography, dentistry, public health, and other relevant healthcare disciplines. A multistage sampling technique will be used to select geopolitical zones, states, institutions, faculties or departments, levels of study, and eligible students. Sign-language awareness training will be assessed using indicators such as exposure to training sessions, frequency and duration of training, knowledge of basic sign-language concepts, common healthcare-related signs, deaf culture and communication preferences, appropriate communication strategies, use of gestures and visual communication, respectful interaction, use of interpreters, communication aids, confidentiality, informed consent, and identification of communication barriers. Communication skills will be assessed using indicators such as ability to initiate communication appropriately, use basic healthcare-related signs, communicate simple health information, ask and respond to basic patient questions, demonstrate active listening, use appropriate non-verbal communication, confirm patient understanding, maintain respectful interaction, support informed communication, and appropriately use interpreters or alternative communication methods when necessary. Data will be collected using structured questionnaires, standardized communication-skills assessment tools, practical sign-language assessments, simulated patient scenarios, observation checklists, and pre-test and post-test assessments where a quasi-experimental intervention is adopted. Descriptive statistics will be used to summarize students' demographic and academic characteristics, previous exposure to sign language, sources of information, awareness levels, and communication-skills scores. Inferential statistical techniques, including chi-square tests, paired and independent t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of sign-language awareness training on communication skills. Where a quasi-experimental design is adopted, communication-skills scores before and after the training intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that sign-language awareness training has a significant positive impact on communication skills among healthcare students in Nigeria. Students exposed to structured, practical, interactive, and disability-inclusive sign-language training are expected to demonstrate improved communication skills when interacting with deaf and hard-of-hearing patients. Training may improve students' ability to use basic healthcare-related signs, communicate simple health information, recognize communication barriers, use appropriate visual and non-verbal communication, and confirm patient understanding. Practical demonstrations, role-playing, simulated patient interactions, and supervised practice may improve students' confidence and reduce anxiety when communicating with patients who use sign language. Training may also strengthen students' understanding of deaf culture, respect for patient autonomy, confidentiality, and the importance of appropriate interpreter use. However, limited availability of qualified sign-language instructors, inadequate curriculum time, limited exposure to deaf patients, lack of interpreters, insufficient training resources, and limited institutional support may reduce the effectiveness of awareness training alone. The study therefore expects practical, competency-based, sustained, and healthcare-focused sign-language awareness training to contribute significantly to improved communication skills among healthcare students in Nigeria. The study is expected to contribute to the literature on sign-language education, deaf and hard-of-hearing healthcare, disability-inclusive communication, healthcare education, patient-centred care, health literacy, communication skills, disability rights, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Federal Ministry of Education, universities, healthcare training institutions, teaching hospitals, professional healthcare bodies, deaf-support organizations, healthcare educators, interpreters, development partners, and policymakers regarding strategies for improving communication accessibility in healthcare. The study will also provide evidence-based recommendations for integrating basic healthcare sign-language training into healthcare curricula, strengthening practical communication training, increasing healthcare students' exposure to deaf and hard-of-hearing patients, improving access to qualified interpreters, promoting disability-inclusive healthcare policies, and developing sustainable educational programmes that equip future healthcare professionals with appropriate communication skills for providing accessible and equitable healthcare services to deaf and hard-of-hearing individuals across Nigeria.
