Cyber wellness includes the knowledge, skills, and values geared toward the protection of Internet users as well as proper and responsible technology use. Using the survey method, this study investigated the cyber wellness awareness of secondary school students and teachers as well as parents' perceptions of their children's cyber wellness. Six thousand eight hundred thirty-nine (6,839) students, 749 teachers, and 4,916 parents participated. Cyber wellness survey forms for students, teachers, and parents were distributed to seven school districts. Results indicated that students had high levels of awareness with regard to Internet addiction, cyberbullying, online privacy, and cybersecurity and medium levels of awareness regarding netiquette, inappropriate online content, and copyright. Additionally, students' awareness levels differed significantly in terms of gender, class level, Internet use span, and desire for education on safe and responsible Internet use. Teachers had medium levels of awareness with respect to all of the concepts. Furthermore, it was determined that parents considered that their children had medium levels of awareness regarding Internet addiction, netiquette, online privacy, inappropriate online content, copyright, and cybersecurity along with a high level of awareness regarding cyberbullying.
