Brief Summary

Adolescence (ages 10-19) is a critical developmental stage in which individuals undergo significant physical, psychological, and social changes. Health behaviors acquired during this period often persist into adulthood, directly influencing both individual and public health. Adolescents' lifestyles are shaped by factors such as family, school, peers, and socio-cultural environment. A healthy lifestyle includes habits such as regular physical activity, balanced nutrition, adequate sleep, and limited screen time, all of which are key determinants of quality of life. The aim of this study is to evaluate the effectiveness of an educational program designed to improve high school students' hygiene, screen use, nutrition, physical activity, and sleep habits. It is hypothesized that the program will increase students' healthy lifestyle beliefs and hygiene behaviors, while reducing screen addiction and insomnia levels.

Outcome Measures

Primary Outcomes (2)

• Healthy Lifestyle Belief Scale for Adolescents

  The Healthy Lifestyle Belief Scale for Adolescents was developed by Kelly et al. (2011), and its Turkish validity and reliability study was conducted by Kudubeş and Bektas (2020). The scale highlights beliefs related to various aspects of maintaining a healthy lifestyle. The scale has a total of 16 items and three subscales.The scale, prepared according to a five-point Likert system, is answered on a scale of "1 = Strongly Disagree" to "5 = Strongly Agree." A minimum of 16 and a maximum of 80 points can be obtained on the entire scale. An increase in the score obtained on the scale indicates an increase in adolescents' belief in healthy living. The Cronbach's alpha coefficient of the scale is 0.90.

  Week 1 = Data collection from all participants. Weeks 2, 3, 4, 5, and 6 = Training provided to the Training Group. Week 7 = Post-test data collection from all participants. Weeks 8, 9, 10, 11, and 12 = Training provided to the Control Group.

• Screen Addiction Scale

  The SAS is a comprehensive measurement tool that covers any screen rather than focusing on specific screen-based devices. The scale can be defined as a synthesis of screen-based addictions such as internet, smartphone, television, social media, computer, and video game addiction. It has been found that the EBÖ has a structure consisting of 21 items and 4 factors. A valid and reliable scale was obtained, validated by a first-order multifactor model and a second-order multifactor model. The scale, prepared according to a five-point Likert system, is answered as "1=Strongly Disagree, 5=Strongly Agree." The scale can yield a minimum score of 21 and a maximum score of 105. High scores on the scale indicate high screen dependency, while low scores indicate low screen dependency. The Cronbach's alpha value, which is the internal consistency coefficient of the scale, is reported to be 0.925.

  Week 1 = Data collection from all participants. Weeks 2, 3, 4, 5, and 6 = Training provided to the Training Group. Week 7 = Post-test data collection from all participants. Weeks 8, 9, 10, 11, and 12 = Training provided to the Control Group.

Secondary Outcomes (2)

• Hygiene Behavior Assessment Scale

  4 Week 1 = Data collection from all participants. Weeks 2, 3, 4, 5, and 6 = Training provided to the Training Group. Week 7 = Post-test data collection from all participants. Weeks 8, 9, 10, 11, and 12 = Training provided to the Control Group.

• Bergen Insomnia Scale (BIS) in Adolescents

  Week 1 = Data collection from all participants. Weeks 2, 3, 4, 5, and 6 = Training provided to the Training Group. Week 7 = Post-test data collection from all participants. Weeks 8, 9, 10, 11, and 12 = Training provided to the Control Group.
