Interrelationship of Health Communication, Health Literacy, Therapeutic Communication and other Related Concepts SEMIU BELLO* Abstract Since the evolution of health communication as a theory and practice, the field has integrated many related concepts from other disciplines into its scholarship and professional practice. As such, scholars have described the field as hybrid and multi-disciplinary. This analysis adopts the explorative framework to discuss the interrelationship of health communication and health literacy, therapeutic communication or patient-provider communication, social and behavioural change communication, social marketing and media literacy. The study is a contribution to health communication scholarship in Nigeria to facilitate better understanding, appreciation and application. Key Words: Health Communication, Media Literacy, Health Literacy, Social Marketing, Social and Behavioural Communication, Therapeutic Communication. Introduction The multi-disciplinary nature of health communication makes scholars in this domain to build their scholarship engagement around relevant and related concepts from other disciplines. In the process, therefore, health communication has adopted a wide range of related concepts from other disciplines and has the potential to adopt many other emerging concepts in the future to enhance and improve health outcomes among members of communities. The nature of human beings, who are described as an enigmatic whole by philosophers (Berdyaev, 1944; Omatseye, 2003; Pessin, 2002), whose nature continues to generate theories and models among scholars; and the complexities that characterise health as a phenomenon are among other justifications for health communication to adopt various concepts from other disciplines in order to achieve its theoretical thrust and practical purposes. This emphasises why health communication is described as a hybrid and interdisciplinary field of inquiry. This is further reflected in its conceptual framework. For instance, health communication is defined asa multifaceted and multidisciplinary approach to reach different audiences and share health- related information with the goal of influencing, engaging and supporting individuals, communities, health professionals, special groups, policymakers and the public to champion, introduce, adopt, or sustain a behaviour, practice, or policy that will ultimately improve health outcomes (Schiavo, 2007).
