This study was conducted with the aim of simultaneously describing the patterns among physical activity attitudes, technology addiction, and psychological well-being in high school students and investigating whether these variables differ by gender. Data were collected from a total of 320 participants aged 13-17, located in four different provinces across various regions of Turkey. Data were gathered using "the Youth Physical Activity Attitude Scale (YPAAS), the Technology Addiction Scale (TAS)," and "the Subjective/Psychological Well-Being Scale." Data were analyzed with SPSS 27.0; following checks for normality of distributions, "descriptive statistics, independent samples t-tests for gender comparison," and "Pearson product-moment correlation" were applied for inter-variable relationships. The findings indicate that students' positive physical activity attitudes and psychological well-being generally trend at a moderate level. Components of technology addiction are also found to be at a moderate level, with relatively higher scores observed in the sub-dimensions of social networking and online gaming use. In gender-based comparisons, no significant differences were determined for physical activity attitudes or psychological well-being; however, significant differences were found in some sub-dimensions of technology addiction. Correlation analyses revealed that a positive physical activity attitude is significantly negatively correlated with indicators of technology addiction and positively correlated with psychological well-being. Conversely, negative attitude exhibited relationships in the opposite direction. The findings suggest that in school-based interventions, it may be beneficial to concurrently target components that reinforce physical activity and enhance digital self-regulation.
