This study was planned as a randomized controlled trial. The 9th and 10th grades of two high schools with the same status in the capital of Türkiye will constitute the sample of the research.Adolescents will be randomized as an intervention and control group after stratification according to the mean score of the scale, gender (girls/boys), and grades (9th and 10th grades). Letters will be given to the intervention and control groups. According to the coin toss method, the letter A will be given to the initiative group and the letter B will be given to the control group. Randomization will be performed by a statistician independent of the research using the www.randomizer.org site. Adolescents will not be informed that they will be an intervention or control group. Criteria for inclusion in the research; (a) continuing their education in the 9th-10th grade, (b) agreeing to participate in the study, (c) giving written consent to participate in the study by their parents, (d) stating t

All forms will be administered to adolescents in the control group twice, before and after the program (except for the descriptive characteristic data form). After the study is completed, the control group will be given the same training and written material.

The content of the program is based on the current literature (Dennison, 2024; Holmqvist Larsson et al., 2020; Kara & Yüksel, 2022; Kılıçarslan & Varol, 2023; Siegel & Brayson, 2021; Vafaei et al., 2021) for four weeks, once a week (average 50 minutes/week). The module on noticing emotions, which will be applied in the first week, is aimed at adolescents to think about and notice emotions. The content of the training will include determining the beliefs and effects of the group members about emotions, teaching the nature of all emotions and the function of adaptation, distinguishing between emotions and thoughts, teaching similar and opposite emotions, and situations that contribute to the positivity of the emotional state.

The Regulation of Emotions Questionnaire (REQ) was developed by Phillips and Power (2007) to determine adolescents' emotion regulation methods. The scale consists of a total of 18 items and 4 sub-dimensions, including 5 Likert types (1 = Never, 5 = Always). Lower dimensions are classified as internal functional emotion regulation (4 items), internal dysfunctional emotion regulation (5 items), extrinsic functional emotion regulation (4 items), and extrinsic dysfunctional emotion regulation (5 items). The scale does not give a total score, scoring is done on the basis of sub-dimensions. As the scores obtained from the sub-dimensions increase, the frequency of the adolescent's emotion regulation method increases according to that sub-dimension, and as the score decreases, the rate of using that method decreases. There are no items that are scored backward. The reliability coefficients for the original study were .72 for intrinsic functional emotion regulation, .76 for dysfunctional emoti

This scale was developed in 1970 by Spielberger et al. to measure the level of State and Trait Anxiety. The scale is used to determine how the individual feels in a certain condition and in a certain area. The scale can be applied to individuals aged 14 and over. The scale consists of two separate sub-scales, 20 of which were developed to measure state and 20 of which were developed to measure trait anxiety, consisting of a total of 40 items of Likert type. In this study, the State Anxiety Scale will be used. The feelings or behaviors specified in the State Anxiety Scale items are answered by choosing one of the options: 1: none, 2: somewhat, 3: a lot, and 4: completely, depending on the severity of such experiences (Spielberg et al., 1971). There are two types of expressions in the scale. These are either inverted or direct statements. Inverted statements express positive emotions, while direct expressions express negative emotions. Scoring on the State Anxiety Scale varies between

It is a 5-point Likert model developed by Liddle and Carter (2015) to measure the emotional and psychological well-being levels of children aged 8-15 and rated between "Never (1) and Always (5)" consisting of 12 question items. There is no inverse matter on the scale. The highest score that can be achieved on the scale is 60, while the lowest score is 12. High scores obtained from the scale indicate that children's emotional and psychological well-being levels are high. In the original study, the internal consistency reliability coefficient of the scale was found to be .85 (Liddle & Carter, 2015). The scale was adapted into Turkish by Akın et al. in 2016. It was applied to primary, secondary, and high school students between the ages of 9-16. In the confirmatory factor analysis conducted for the adaptation studies to Turkish, it was seen that the one-dimensional model was well adapted. The Cronbach-Alpha internal consistency coefficient calculated within the scope of this study was fo
