	abstract = {This two-wave study aimed to adapt the Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS) to the Turkish language and cultural context. At Time 1, participants included 1033 Turkish high school students (Mage = 15.91, SD = 0.36; 41.9\% female) from 26 public schools located in Ankara, T{\"u}rkiye. At Time 2, 849 students continued to participate in the study. A series of CFA provided support to the originally proposed six-factor solution of the BPNSFS and its time invariance along a 6-month period. The results also revealed that in addition to the six-factor model, the Multi-Trait, Multi-Method (MTMM) model could also be used in future research. In addition, testing the reliability and validity of the scale, regression analyses showed that satisfaction of the three needs positively predicted life satisfaction and negatively predicted depressive feelings, while an opposite trend was observed for the need frustration. Our findings suggest that the Turkish version of the scale is reliable and carries similar psychometric features to the original version. {\textcopyright} 2025 Wiley Periodicals LLC.},
