SWLS, satisfaction with life scale; HSCL-5, Hopkins symptom checklist – 5 items; EDS, eating disturbance scale; SOC, sence of coherence (reversed); SES, socioeconomic status; PAQ, personal attributes questionnaire; LP, literacy problems. Correlations are reported as Pearson’s r. N ranges from 1,192 (dropout vs. GPA) to 1,674 (gender vs. birthyear). ³ p < 0.001, ² p < 0.01, and ¹ p < 0.05.
