Parental Reflective Functioning and Object Relations in Adolescents: A Path Model of the Direct and Indirect Effects on Reactive Aggression through Mentalization
type: item
description: Objective: The present study aimed to investigate the direct and indirect effects of parental reflective functioning and object relations on reactive aggression among adolescents through the mediating role of mentalization. Methods and Materials: This study employed a descriptive-correlational design based on path analysis. The statistical population included adolescents enrolled in the second cycle of secondary education (grades 10–12) during the 2025–2026 academic year. Participants were selected using a multistage cluster sampling method, and after screening incomplete responses, the final sample consisted of 463 adolescents aged 15–18 years. Data were collected using the Parental Reflective Functioning Questionnaire–Adolescent Version (PRFQ-A), Bell Object Relations and Reality Testing Inventory (BORRTI), Reflective Functioning Questionnaire for Youth (RFQY), and Reactive–Proactive Aggression Questionnaire (RPQ). Data analysis was performed using SPSS version 27 and AMOS version 26. Descriptive statistics, Pearson correlation analysis, and path analysis with bootstrap estimation were used to examine direct and indirect relationships among variables. Findings: The results showed that parental reflective functioning significantly and positively predicted mentalization (β = 0.389, p < .001), and object relations also had a significant positive effect on mentalization (β = 0.208, p < .001). Mentalization significantly and negatively predicted reactive aggression (β = -0.447, p < .001). Furthermore, parental reflective functioning (β = -0.145, p < .001) and object relations (β = -0.183, p < .001) had significant direct negative effects on reactive aggression. Bootstrap analysis confirmed the significant mediating role of mentalization in the relationship between parental reflective functioning and reactive aggression (indirect effect = -0.174, 95% CI [-0.224, -0.129]) and between object relations and reactive aggression (indirect effect = -0.093, 95% CI [-0.140, -0.0…

Dynamic Bayesian Networks of Self-Esteem Fluctuations and Social Feedback Sensitivity
type: item
description: Objective: The present study aimed to model the dynamics of state self-esteem fluctuations and social feedback sensitivity using Dynamic Bayesian Networks. Methods and Materials: A quantitative intensive longitudinal design was implemented with 287 university students from Slovenia who completed a 21-day ecological momentary assessment protocol. Participants responded to five semi-random prompts per day assessing state self-esteem, perceived social feedback valence, and negative affect, yielding 26,874 momentary observations. Baseline measures included trait self-esteem, rejection sensitivity, depressive symptoms, and social anxiety. Data were person-mean centered and preprocessed to ensure stationarity. A multilevel vector autoregressive model was first estimated to identify preliminary lagged associations. Subsequently, Dynamic Bayesian Networks were constructed using a two-time-slice framework with hill-climbing structure learning and Bayesian Information Criterion scoring. Bootstrapped model averaging (1,000 resamples) ensured stability of directed edges. Hierarchical Bayesian extensions examined moderation by trait rejection sensitivity, and predictive accuracy was evaluated via 10-fold cross-validation. Findings: State self-esteem demonstrated significant autoregressive stability (β ≈ 0.50, p < 0.001). Positive social feedback prospectively predicted increases in subsequent state self-esteem (β ≈ 0.24, credible intervals excluding zero), whereas negative affect predicted decreases (β ≈ -0.20, p < 0.001). Reciprocal effects between self-esteem and negative affect formed a significant feedback loop. Trait rejection sensitivity significantly moderated the feedback-to-self-esteem pathway, amplifying evaluative reactivity (posterior mean ≈ 0.15, credible intervals excluding zero). Bootstrapped inclusion probabilities for key edges exceeded 90%, and cross-validated predictive performance demonstrated satisfactory out-of-sample accuracy (RMSE ≈ 0.41). Conclusion: Sel…

Data were collected using standardized instruments including the Kessler Psychological Distress Scale, Cyberbullying Victimization Scale, UCLA Loneliness Scale, Educational Stress Scale for Adolescents, a screen-time fragmentation measure, and the Family Environment Scale. Data analysis involved descriptive statistics, Pearson correlation coefficients, and deep neural network modeling using Python, TensorFlow, and Keras libraries. Model performance was evaluated using mean squared error, root mean squared error, mean absolute error, coefficient of determination, and cross-validation procedures. SHAP analysis was additionally employed to examine relative predictor importance. Findings: The findings demonstrated significant positive relationships between psychological distress and cybervictimization, loneliness, academic pressure, and screen-time fragmentation, while family emotional climate showed a significant negative relationship with psychological distress. Loneliness emerged as the strongest predictor within the deep neural network model, followed by family emotional climate and cybervictimization. Conclusion: Comparative analyses indicated that the deep neural network outperformed traditional machine learning approaches including…

Designing a Positive Psychological Self-Care Educational Package for Male Adolescents with High-Risk Behaviors
type: item
description: Objective: The present study aimed to design and validate a positive psychological self-care educational package for male adolescents with high-risk behaviors. Methods and Materials: This study was conducted using a qualitative applied research design based on grounded theory and thematic analysis. The study population included psychologists with direct professional experience working with adolescents with high-risk behaviors, theoretical and empirical literature related to positive psychology and psychological self-care, and university experts in psychology. Twenty-two psychologists working in counseling centers affiliated with the Department of Education in Tehran were selected through purposive sampling and participated in semi-structured interviews until theoretical saturation was achieved. In addition, domestic and international scientific sources related to positive psychology, self-care, emotion regulation, coping self-efficacy, and adolescent high-risk behaviors were reviewed and analyzed. Data collection tools included semi-structured interviews, a researcher-made content validity form, and an inter-rater agreement form. Data were analyzed through open, axial, and selective coding. After the educational package was developed, six faculty experts evaluated its content validity and overall quality. Findings: The qualitative analysis resulted in the extraction of 60 initial codes, which were organized into 12 main categories, including communication establishment, emotion recognition, recognition of strengths, optimism, stress management, anger management, social skills, empathy, gratitude, meaning in life, spirituality, and resilience. These categories formed the conceptual and structural foundation of the final 12-session positive psychological self-care educational package. The package integrated emotional, cognitive, interpersonal, and resilience-oriented components designed to improve adolescents’ psychological self-care capacities and coping resources. C…

type: item
description: Objective: The present study aimed to determine the effectiveness of Compassion-Focused Therapy (CFT) on internalized shame and self-criticism in adolescent girls with body image concerns. Materials and Methods: This was a quasi-experimental study with a pretest–posttest design and a two-month follow-up with a control group. The statistical population consisted of 13- to 18-year-old adolescent girls with body image concerns in Tehran in 2026. After administering the Body Image Concern Inventory developed by Littleton, Axsom, and Pury, adolescents who scored above 52 were identified as individuals with body image concerns. Subsequently, 30 eligible participants were selected through purposive sampling and randomly assigned to an experimental group and a control group, with 15 participants in each group. The experimental group received Compassion-Focused Therapy based on Gilbert’s protocol (Gilbert, 2009) in eight 60-minute sessions, whereas the control group received no intervention during this period. Data were collected using the Internalized Shame Scale developed by Cook (1993) and the Self-Criticism Scale developed by Gilbert et al. (2004). Data were analyzed using the independent samples t-test, Fisher’s exact test, and two-way repeated measures analysis of variance in IBM SPSS Statistics. Findings: The results indicated that the experimental and control groups did not differ significantly in terms of demographic characteristics. Furthermore, the results of the two-way repeated measures analysis of variance showed that the interaction effect of group and time on internalized shame and self-criticism was statistically significant. Based on mean comparisons, the scores of internalized shame and self-criticism in the experimental group decreased from the pretest to the posttest stage, and this reduction largely remained stable at the two-month follow-up stage, whereas no substantial changes were observed in the control group.

type: item
description: Objective: The present study aimed to predict cyberbullying–cybervictimization experience based on parent–child relationship, psychological well-being, and internet addiction among adolescents in Isfahan City. Methods and Materials: The present study employed a descriptive-correlational design. The statistical population consisted of all male and female high school students enrolled during the 2024–2025 academic year in Isfahan City. Based on Morgan’s table, 382 students were selected using cluster random sampling. Data were collected using Young’s Internet Addiction Test (1998), the Cyber Bullying–Victimization Experience Questionnaire developed by Antoniadou et al. (2016), Ryff’s Short Form Psychological Well-Being Scale (1989), and Pianta’s Parent–Child Relationship Scale (2011). Data analysis was conducted using Pearson correlation coefficients and multiple linear regression analysis through SPSS version 27. Findings: The findings demonstrated that internet addiction had a significant positive relationship with cyberbullying–cybervictimization experience (β = 0.886, p < .001), whereas psychological well-being had a significant negative relationship with cyberbullying–cybervictimization experience (β = -0.154, p < .001). However, the overall parent–child relationship did not significantly predict cyberbullying–cybervictimization experience (β = -0.002, p = .959). The regression model was statistically significant (F = 208.95, p < .001) and explained 62.5% of the variance in cyberbullying–cybervictimization experience. In addition, the closeness component of the parent–child relationship showed a significant negative correlation with both cybervictimization and cyberbullying, whereas the conflict component demonstrated a significant positive correlation with these variables. No significant relationship was found between the dependency component and cyberbullying–cybervictimization. Conclusion: The findings indicate that internet addiction and psychological well-be…

Dynamic Bayesian Networks of Self-Esteem Fluctuations and Social Feedback Sensitivity
type: item
description: Objective: The present study aimed to model the dynamics of state self-esteem fluctuations and social feedback sensitivity using Dynamic Bayesian Networks. Methods and Materials: A quantitative intensive longitudinal design was implemented with 287 university students from Slovenia who completed a 21-day ecological momentary assessment protocol. Participants responded to five semi-random prompts per day assessing state self-esteem, perceived social feedback valence, and negative affect, yielding 26,874 momentary observations. Baseline measures included trait self-esteem, rejection sensitivity, depressive symptoms, and social anxiety. Data were person-mean centered and preprocessed to ensure stationarity. A multilevel vector autoregressive model was first estimated to identify preliminary lagged associations. Subsequently, Dynamic Bayesian Networks were constructed using a two-time-slice framework with hill-climbing structure learning and Bayesian Information Criterion scoring. Bootstrapped model averaging (1,000 resamples) ensured stability of directed edges. Hierarchical Bayesian extensions examined moderation by trait rejection sensitivity, and predictive accuracy was evaluated via 10-fold cross-validation. Findings: State self-esteem demonstrated significant autoregressive stability (β ≈ 0.50, p < 0.001). Positive social feedback prospectively predicted increases in subsequent state self-esteem (β ≈ 0.24, credible intervals excluding zero), whereas negative affect predicted decreases (β ≈ -0.20, p < 0.001). Reciprocal effects between self-esteem and negative affect formed a significant feedback loop. Trait rejection sensitivity significantly moderated the feedback-to-self-esteem pathway, amplifying evaluative reactivity (posterior mean ≈ 0.15, credible intervals excluding zero). Bootstrapped inclusion probabilities for key edges exceeded 90%, and cross-validated predictive performance demonstrated satisfactory out-of-sample accuracy (RMSE ≈ 0.41). Conclusion: Sel…

The Relationship Between Maladaptive Perfectionism and Academic Burnout with Students’ Mental Health: The Mediating Role of Spiritual Intelligence
type: item
description: Objective: The present study aimed to investigate the relationship between maladaptive perfectionism and academic burnout with students’ mental health through the mediating role of spiritual intelligence. Methods and Materials: This study was conducted using a descriptive-correlational design based on structural equation modeling. The statistical population included all high school students in Tehran during the 2025–2026 academic year. A total of 412 students were selected through multistage cluster random sampling. Data were collected using the Frost Multidimensional Perfectionism Scale, Maslach Burnout Inventory–Student Survey, General Health Questionnaire-28, and Spiritual Intelligence Self-Report Inventory. Descriptive statistics and Pearson correlation coefficients were calculated using SPSS-27 software, and structural equation modeling was performed using AMOS-24. The significance of indirect effects was examined using the bootstrap method. Findings: The findings demonstrated that maladaptive perfectionism had a significant positive relationship with academic burnout (r = 0.51, p < 0.01) and mental health problems (r = 0.58, p < 0.01). Academic burnout was also positively associated with mental health problems (r = 0.61, p < 0.01). In contrast, spiritual intelligence showed significant negative relationships with maladaptive perfectionism (r = -0.46, p < 0.01), academic burnout (r = -0.49, p < 0.01), and mental health problems (r = -0.55, p < 0.01). Structural equation modeling indicated that maladaptive perfectionism directly predicted mental health problems (β = 0.37, p < 0.001), while academic burnout also had a significant direct effect on mental health problems (β = 0.41, p < 0.001). Spiritual intelligence significantly mediated the relationships between maladaptive perfectionism, academic burnout, and mental health. The proposed model demonstrated acceptable fit indices (χ²/df = 2.31, CFI = 0.94, TLI = 0.93, RMSEA = 0.057). Conclusion: The findings sugge…

Predicting Self-Esteem Instability Using Rejection Sensitivity, Daily Stress Reactivity, Social Feedback Valence, and Emotional Reactivity in LSTM Models
type: item
description: Objective: To evaluate the efficacy of a Long Short-Term Memory ( ) neural network in predicting intra-individual self-esteem instability utilizing continuous ecological momentary assessment data encompassing trait rejection sensitivity, daily stress reactivity, social feedback valence, and momentary emotional reactivity. Methods and Materials: A longitudinal Ecological Momentary Assessment study was conducted over days with a final sample of young adults from Spain. Participants completed the Rejection Sensitivity Questionnaire and responded to multiple daily prompts assessing momentary stress, social feedback valence, emotional reactivity, and state self-esteem. An neural network was designed to capture the non-linear, time-dependent relationships within this multi-dimensional data, and its performance was benchmarked against traditional linear regression and standard Recurrent Neural Network ( ) architectures. Findings: The proposed architecture significantly outperformed baseline models, capturing of the variance in self-esteem instability ( ) with a low prediction error ( ). Permutation feature importance analysis revealed that momentary emotional reactivity and trait rejection sensitivity were the strongest predictors of self-esteem fluctuations. Additionally, an ablation study on look-back windows identified a -hour period ( assessments) as the optimal temporal framework for forecasting instability. Conclusion: Advanced deep learning models, specifically networks, can accurately decode the complex, non-linear temporal dynamics of self-esteem, providing a powerful computational foundation for future personalized, real-time psychological interventions.

Predicting Problematic Internet Use via Impulsivity, Emotion Dysregulation, Reward-System Reactivity, and Loneliness Using SVM Models
type: item
description: Objective: The present study aimed to predict the severity of problematic internet use by examining the complex interplay of impulsivity, emotion dysregulation, reward-system reactivity, and loneliness utilizing advanced Support Vector Machine (SVM) models. Methods and Materials: A cross-sectional predictive design was employed, collecting self-reported data from a sample of Argentine adults using validated psychometric questionnaires to measure problematic internet use, impulsivity, emotion dysregulation, reward-system reactivity, and subjective loneliness. Data analysis involved preliminary bivariate correlations and the application of machine learning classification algorithms, specifically training and evaluating various SVM kernels to distinguish between high and low-to-moderate problematic internet users. Finally, permutation feature importance techniques were utilized to rank the predictive weight of the psychological constructs within the optimal model. Findings: Preliminary bivariate analyses revealed significant positive correlations between problematic internet use and all predictor variables, most notably emotion dysregulation ( ) and impulsivity ( ). The Radial Basis Function (RBF) kernel emerged as the optimal SVM model, demonstrating robust predictive capability with an overall classification accuracy of and an F1-score of . Furthermore, permutation feature importance analysis identified emotion dysregulation as the most critical predictor of pathological digital behavior, followed sequentially by impulsivity, loneliness, and reward-system reactivity. Conclusion: Problematic internet use is profoundly driven by underlying deficits in emotional and behavioral self-regulation, underscoring the necessity for targeted psychological interventions that address these core vulnerabilities rather than merely restricting screen time.

Machine‑Learning Identification of Subtypes of Adolescent Perfectionism Based on Concern Over Mistakes, Parental Expectations, Cognitive Rigidity, and Negative Affect
type: item
description: Objective: The objective of this study was to identify distinct latent subtypes of adolescent perfectionism by applying unsupervised machine-learning algorithms to a comprehensive set of variables, specifically concern over mistakes, parental expectations, cognitive rigidity, and negative affect. Methods and Materials: The research utilized a cross-sectional, school-based design, sampling adolescents from Germany. Data were gathered using standardized self-report instruments to measure the four target variables, with all raw scores converted to standardized -scores. Following data preprocessing, unsupervised machine learning via Gaussian Mixture Modeling (GMM) was employed to uncover latent subpopulations, evaluating models ranging from two to six classes using fit indices such as the Bayesian Information Criterion and the Bootstrapped Likelihood Ratio Test. Findings: The GMM algorithm identified an optimal three-class structural model (Entropy = ). The sample was categorized into Class : Low Perfectionism ( , ); Class : Externally Pressured Perfectionism ( , ), defined predominantly by elevated perceived parental expectations ( ); and Class : Maladaptive Perfectionism ( , ), characterized by pervasive elevations across all domains, notably severe negative affect ( ) and extreme cognitive rigidity ( ). Demographic analyses revealed significant differences, indicating that older adolescents ( , ) and females ( , ), who comprised of Class , were significantly overrepresented in the Maladaptive Perfectionism profile. Conclusion: Adolescent perfectionism manifests in distinct multivariate phenotypes, highlighting the critical necessity of identifying high-risk, maladaptive subtypes to deliver highly targeted clinical interventions focusing on cognitive flexibility and emotion regulation.

Participants completed a comprehensive, multimodal assessment protocol comprising the Generalized Anxiety Disorder Assessment- (GAD- ) to classify anxiety severity, the Penn State Worry Questionnaire for Children to measure conscious worry severity, and the Conflict Behavior Questionnaire to assess parent-child conflict. Implicit neurocognitive attentional bias to threat was quantified using a computerized dot-probe task. Concurrently, continuous electrocardiography and electrodermal activity recordings were utilized to capture objective physiological arousal, specifically heart rate variability and skin conductance responses. A Deep Neural Network architecture was subsequently constructed, trained, and tested to model the complex, non-linear relationships among these disparate variables and predict adolescent generalized anxiety classification. Findings: The trained Deep Neural Network demonstrated exceptional predictive performance, achieving an overall classification accuracy of and an Area Under the Receiver Operating Characteristic Curve of on unseen testing data. Feature importance analysis derived from the network’s weights revealed that physiological arousal constituted the largest broad predictive domain ( total; comprising for heart rate variability and for skin conductance responses). Conscious worry severity emerged as the strongest individual predictor, accounting for of the model’s predictive capacity. Furthermore, environmental and neurocognitive factors contributed significantly to the predictive architecture, with parent-child conflict accounting for and attentional bias to threat accounting for of the model’s weight. Conclusion: Multimodal deep…

type: item
description: Objective: The present study aimed to investigate the relationship between schema modes, psychological flexibility, and alexithymia with subjective well-being among university students in Qazvin. Methods and Materials: This study was a fundamental, descriptive-correlational research conducted among students of Imam Khomeini International University during the 2022–2023 academic year. A total of 305 participants were selected using multistage cluster random sampling. Data were collected using the Satisfaction with Life Scale (SWLS), the Positive and Negative Affect Schedule (PANAS), the Schema Mode Questionnaire, the Psychological Flexibility Questionnaire, and the Toronto Alexithymia Scale (TAS-20). After obtaining informed consent, questionnaires were administered, and data were analyzed using descriptive statistics, Pearson correlation coefficients, and multiple regression analysis via SPSS. Findings: The results indicated that maladaptive schema modes (child modes, maladaptive parent modes, and maladaptive coping modes) were significantly negatively correlated with life satisfaction and positive affect and positively correlated with negative affect (p < .01). In contrast, adaptive schema modes showed significant positive correlations with life satisfaction and positive affect and negative correlations with negative affect (p < .01). Psychological flexibility was positively associated with life satisfaction (β = 0.19, p < .001) and positive affect (β = 0.42, p < .001), and negatively associated with negative affect (β = -0.23, p < .001). Alexithymia demonstrated significant negative relationships with life satisfaction (β = -0.35, p < .001) and positive affect (β = -0.38, p < .001), and a positive relationship with negative affect (β = 0.39, p < .001). Regression analyses further revealed that schema modes accounted for the largest proportion of variance in subjective well-being components, followed by alexithymia and psychological flexibility. Conclusion: The fin…

A Gradient‑Boosting Model of Adolescent Social Anxiety Incorporating Rejection Sensitivity, Intolerance of Uncertainty, Emotional Reactivity, and Peer Network Centrality
type: item
description: Objective: This study aimed to develop a highly predictive machine learning model to delineate the complex, non-linear, and synergistic contributions of rejection sensitivity, intolerance of uncertainty, emotional reactivity, and peer network centrality to adolescent social anxiety. Methods and Materials: A cross-sectional design was employed with a sample of adolescents (ages ) recruited from schools in Armenia via multistage cluster sampling. Participants completed validated Armenian translations of the Social Anxiety Scale for Adolescents (SASA), Rejection Sensitivity Questionnaire (RSQ), Intolerance of Uncertainty Scale (IUS-12), and the Emotion Reactivity Scale (ERS). Peer network centrality was quantified using eigenvector centrality scores derived from a sociometric nomination procedure. An Extreme Gradient Boosting (XGBoost) algorithm was trained and optimized using randomized search cross-validation, with model interpretability established through SHapley Additive exPlanations (SHAP). Findings: The final XGBoost model demonstrated robust predictive power on the unseen test set, explaining of the variance in social anxiety scores ( , RMSE , MAE ). Global feature importance analysis, based on mean absolute SHAP values, identified emotional reactivity as the most dominant predictor (Mean SHAP value ), followed by rejection sensitivity (Mean SHAP value ), intolerance of uncertainty (Mean SHAP value ), and peer network centrality (Mean SHAP value ). SHAP analysis further revealed significant synergistic effects, particularly between high emotional reactivity and high rejection sensitivity, which exponentially increased predicted social anxiety. Conclusion: Emotional reactivity operates as the primary driver of adolescent social anxiety, with its impact significantly amplified by concurrent cognitive and social vulnerabilities, highlighting the necessity of integrated, skills-based clinical interventions.

Predicting Adolescent Depressive Symptom Severity from Rumination, Sleep Variability, and Heart-Rate Variability Using Multimodal Deep Learning
type: item
description: Objective: The objective of this study was to develop and evaluate a multimodal deep learning architecture capable of predicting adolescent depressive symptom severity by dynamically integrating static cognitive rumination scores with continuous, time-series sequences of sleep variability and heart-rate variability. Methods and Materials: A two-week prospective observational study was conducted involving adolescents (ages ) from urban and semi-urban districts of Lagos, Nigeria. Baseline cognitive vulnerability and depressive symptoms were assessed via self-report using the Ruminative Responses Scale (RRS) and the Patient Health Questionnaire for Adolescents (PHQ-A). Continuous physiological data, specifically nocturnal sleep variability (standard deviation of total sleep time) and heart-rate variability (HRV; specifically RMSSD), were collected continuously using wrist-worn actigraphy and photoplethysmography (PPG) devices. Data analysis was executed using a hybrid multimodal deep learning architecture featuring late fusion, which utilized Long Short-Term Memory (LSTM) networks to process the physiological time-series data and a Multilayer Perceptron (MLP) for the static cognitive data. The model was trained using the Adam optimizer to minimize Mean Squared Error and evaluated utilizing -fold cross-validation. Findings: The final sample had a mean age of years ( ), with baseline PHQ-A scores of ( ) and baseline RRS scores of . Bivariate analyses indicated that follow-up depression severity was significantly predicted by rumination ( ), sleep variability ( ), and nocturnal RMSSD ( ). The multimodal late-fusion network demonstrated exceptional predictive accuracy ( , ), substantially outperforming all isolated unimodal models (Static MLP ; Sleep LSTM ; HRV LSTM ). Ablation studies confirmed the necessity of all modalities and temporal dynamics; excluding the rumination feature caused a significant performance drop ( ), and replacing the time-series physiological seque…

Effectiveness of an Academic Motivation Training Model on Cognitive Flexibility, Academic Resilience, and Academic Motivation among Female Lower Secondary School Students in Tehran
type: item
description: Objective: The present study aimed to examine the effectiveness of an academic motivation training model on cognitive flexibility, academic resilience, and academic motivation among female students in lower secondary schools in Tehran. Methods and Materials: This applied study employed a quasi-experimental design with a pretest–posttest format and a control group. The statistical population consisted of all female lower secondary school students in Tehran during the 2025–2026 academic year. Based on sample size estimation using G*Power software and Cohen’s criteria, 42 participants were selected through convenience sampling and randomly assigned to an experimental group (n = 21) and a control group (n = 21). The experimental group received training based on the academic motivation model over eight sessions, while the control group received no intervention. Research instruments included the Cognitive Flexibility Inventory developed by Dennis and Vander Wal (2010), the Academic Motivation Scale by Vallerand et al. (1992), and the Academic Resilience Scale by Cassidy (2016). Data were analyzed using analysis of covariance (ANCOVA) in SPSS at a significance level of 0.05. Findings: The results indicated that, after controlling for pretest effects, the academic motivation training model had a positive and statistically significant effect on cognitive flexibility, academic resilience, and academic motivation (p < 0.001). Specifically, significant differences were observed between the two groups in posttest scores for cognitive flexibility (F = 24.82, η² = 0.39), academic resilience (F = 32.27, η² = 0.46), and academic motivation (F = 43.80, η² = 0.53). Conclusion: Based on the findings, the academic motivation training model can be considered an effective educational intervention that enhances academic motivation, increases cognitive flexibility, and strengthens academic resilience among students. Therefore, implementing this model in educational settings and school couns…
