About this study
Official title: Examination of the Effect of a Psychoeducational-Developmental Support Program on Adolescents' Relative Deprivation, Distress Levels, Peer Relationships, and Basic Psychological Needs
This study evaluated the effectiveness of a Psychoeducational-Developmental Support Program on adolescents' relative deprivation, distress-eustress levels, peer relationships, and basic psychological needs.
The study employed a non-randomized, pretest-posttest quasi-experimental design with a control group. A total of 52 ninth-grade students aged 14-15 years from two high schools in Çekmeköy, Istanbul, Türkiye, participated in the study. The intervention group consisted of 26 students, and the control group consisted of 26 students.
The intervention group received an 11-session Psychoeducational-Developmental Support Program, while the control group received no study-specific intervention. Both groups completed pretest and posttest assessments. A follow-up assessment was administered only to the intervention group approximately one month after the intervention to evaluate the maintenance of program effects.
Read the detailed description
This study evaluated the effectiveness of a Psychoeducational-Developmental Support Program on adolescents' relative deprivation, distress-eustress levels, peer relationships, and basic psychological needs.
The study employed a non-randomized, pretest-posttest, quasi-experimental design with a control group. The final study sample consisted of 52 ninth-grade students aged 14-15 years attending two high schools in Çekmeköy, Istanbul, Türkiye. The intervention group included 26 students, and the control group included 26 students.
Participants were selected based on baseline psychosocial assessments. The intervention and control groups were formed at separate schools without random allocation, taking baseline characteristics and psychosocial risk scores into consideration.
The intervention group received an 11-session Psychoeducational-Developmental Support Program totaling 945 minutes. The program was developed based on a needs assessment conducted with teachers and included structured activities supporting adolescents' social-emotional development, relative deprivation, stress management, peer relationships, and basic psychological needs. The intervention was implemented between March 6 and June 12, 2026. The control group received no study-specific intervention.
Data were collected using the Relative Deprivation Scale-Adolescent Form, the Distress-Eustress Scale for Adolescents (Turkish Form), the Peer Relationships Scale, and the Basic Psychological Needs at School Scale.
Pretest assessments were conducted between February 23 and March 2, 2026, and posttest assessments between June 11 and June 15, 2026. A follow-up assessment was administered only to the intervention group between July 14 and July 16, 2026.
Data were analyzed using descriptive statistics, independent-samples t-tests, paired-samples t-tests, and effect-size analyses. Statistical significance was evaluated at p < .05.

What is being measured
The primary outcome is the main question the study is designed to answer.
Distress-Eustress Levels
Change in adolescents' distress-eustress levels from pre-test to post-test as measured by the Distress-Eustress Scale for Adolescents (Turkish Form). Higher distress scores indicate greater emotional strain; higher eustress scores indicate positive stress response.
Measured: Baseline (pre-test) and post-intervention (11 weeks).
Secondary outcomes (3)
Relative Deprivation
Change in adolescents' perceived relative deprivation measured by the Relative Deprivation Scale-Adolescent Form from pre-test to post-test. Higher scores indicate greater perceived deprivation.
Measured: Baseline and post-intervention (11 weeks).
Peer Relationships
Change in adolescents' peer relationship quality measured by the Peer Relations Scale from pre-test to post-test. Higher scores indicate better peer relationship functioning.
Measured: Baseline and post-intervention (11 weeks).
Basic Psychological Needs at School
Change in adolescents' satisfaction of basic psychological needs measured by the Basic Psychological Needs at School Scale from pre-test to post-test. Higher scores indicate greater need satisfaction.
Measured: Baseline and post-intervention (11 weeks).

- Model description
- This study employed a two-arm, parallel-group, non-randomized quasi-experimental design with pretest and posttest assessments. Participants were recruited from two different high schools in Çekmeköy, Istanbul, Türkiye. One school served as the intervention group (n = 26), and the other served as the no-intervention control group (n = 26). Group allocation was based on school participation and permissions rather than random assignment. The intervention group received an 11-session psychoeducational-developmental support program. Both groups completed pretest and posttest assessments, while a one-month follow-up assessment was conducted only with the intervention group.
