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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
64

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
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
