Note. Effect size d values≥ 0.20, 0.50, and 0.80 mark small, medium, and large effects, respectively (Cohen, 1988). C–CT = continuation phase cognitive therapy; A–CT = acute phase cognitve therapy; best = ratings at one’s best; AFF = afilliation; AUT = autonomy; worst = ratings at one’s worst.

^*p < .05, two-tailed.

^†p ≤ .05, one-tailed.
