Scores on the State-Trait Anxiety Inventory (STAI) varied with both sex and timing of pubertal onset. On both state and trait subscales, females had higher scores than did males. In addition, early-maturing individuals, whether male or female, scored highest on anxiety measures. Significant differences between females (F) and males (M) and between early (E), on-time (OT), and late (L) maturers are indicated in the figure. Analyses are based on 180/179 (State/Trait) early maturing men, 288 on-time maturing men, 172 late maturing men, 217 early maturing women, 300/301 on-time maturing women, and 193 late maturing women.
