School-Based Environmentally Friendly Health Practices on Adolescents

January 31, 2026 updated by: Alime Selçuk Tosun, Selcuk University

The Effect of School-Based Environmentally Friendly Health Practices on Adolescents' Environmental Awareness, Sensitivity, and Well-Being Levels

This study was conducted to investigate the effect of a school-based environmentally friendly healthy practices program implemented among adolescents on the development of environmental awareness and sensitivity (environmental attitudes, environmental literacy, and recycling behaviors) and well-being levels. This research was carried out using a parallel-group randomized controlled experimental design. The study was conducted at a Secondary School. A total of 64 students participated in the study, with 32 students in the intervention group and 32 students in the control group. The School-Based Environmentally Friendly Healthy Practices Program, consisting of seven sessions, was implemented for the students. In addition to this program, a rhythmic exercise program was applied to the students for six weeks. Data were collected using a Personal Information Form. Environmental Attitude Scale, the Recycling Scale for Secondary School Students, and the Environmental Literacy Scale. Well-being levels were evaluated using the Five-Dimensional Well-Being Model for Adolescents: the EPOCH Scale.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: School-Based Environmentally Friendly Healthy Practices
Participants in the intervention arm received a School-Based Environmentally Friendly Healthy Practices Program consisting of seven sessions. The program aimed to improve environmental awareness and sensitivity (environmental attitudes, environmental literacy, and recycling behaviors) as well as psychological well-being. In addition to the main program, participants engaged in a rhythmic exercise program for six weeks.
Other: School-Based Environmentally Friendly Healthy Practices Program
Participants in the intervention arm received a School-Based Environmentally Friendly Healthy Practices Program consisting of seven sessions. The program aimed to improve environmental awareness and sensitivity (environmental attitudes, environmental literacy, and recycling behaviors) as well as psychological well-being. In addition to the main program, participants engaged in a rhythmic exercise program for six weeks.
No Intervention: Usual Care Control Group
Participants in the control arm did not receive the School-Based Environmentally Friendly Healthy Practices Program. They continued their routine school activities.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Environmental Attitude Scale
Time Frame: At baseline and one week after completion of the intervention
The scale assesses environmental attitudes through cognitive, affective, and psychomotor dimensions. The scale consists of cognitive, affective, and psychomotor subscales. Each subscale is treated as a separate construct in line with the multidimensional conceptualization of environmental attitude. The cognitive subscale consists of 22 items, with possible scores ranging from 22 to 110. The affective subscale includes 17 items, and scores that can be obtained from this subscale range between 17 and 85. The psychomotor subscale comprises 20 items, with minimum and maximum possible scores of 20 and 100, respectively. High scores on the subscales indicate a high level of environmental attitude.
At baseline and one week after completion of the intervention

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recycling Scale for Secondary School Students
Time Frame: At baseline and one week after completion of the intervention
The scale evaluates the perceptions of secondary school students regarding recycling. The scale has three subscales: participation, valuing, and contribution to the economy. The scale does not have a total score. The obtainable scores for the subscales range from 5 to 25 for the participation subscale, 5 to 25 for the valuing subscale, and 5 to 20 for the contribution to the economy subscale. A high score obtained from the three subscales indicates a high level of recycling status.
At baseline and one week after completion of the intervention
Environmental Literacy Scale
Time Frame: At baseline and one week after completion of the intervention
Environmental literacy was evaluated using the Environmental Literacy Scale. The minimum score that can be obtained from the scale is 20, and the maximum score is 100. A high score obtained on the scale indicates a high level of environmental literacy.
At baseline and one week after completion of the intervention
Psychological well-being score
Time Frame: At baseline and one week after completion of the intervention
Psychological well-being was assessed using the Five-Dimensional Well-Being Model for Adolescents (EPOCH Scale). The scale consists of five subscales: engagement, perseverance, optimism, connectedness and happiness. The minimum score that can be obtained from the scale is 20, and the maximum score is 100. Higher scores indicate higher levels of adolescent well-being.
At baseline and one week after completion of the intervention
