Means and Standard Deviations by Group for Rumination Induction

	BPD Group	Control Group	F(df)	Sig.	η_p²
1. Baseline NA	18.89 (6.15)	12.66 (4.25)	9.2(1, 77)	.003^*	.11
2. Post-Induction NA	25.63 (7.46)^{^}	17.54 (7.80)	7.7(1, 77)	.007^*⁺	.09
3. Baseline PA	21.46 (8.42)	26.20 (7.88)	.02 (1, 77)	ns	--
4. Post-Induction PA	17.15 (8.00)^□	22.10 (8.92)^□	.22 (1, 77)	ns	--
5. BDI-II Total	20.4 (10.08)	6.48 (5.20)	64.4(1, 77)	.001^*	.44

indicates significant between-group effect, after controlling for BDI-II total.

⁺

indicates a significant group*time interaction such that the BPD group experienced greater reactivity of negative affect than the control group [F(1, 77)=5.42, p<.05, η_p²=.07]

^{^}

indicates significant within-group increase in negative affect (F(1, 37)=12.6, p<.01, η_p²=.25)

^□

indicates a significant within-group decrease of Post-Induction Positive Affect (F(1, 39) = 11.03, p<.01, η_p²=.22)

^□

indicates a significant within-group decrease of Post-Induction Positive Affect (F(1, 37) = 13.7, p<.01, η_p²=.27)
