Table 2.

Momentary attentional control, trait attentional control, and dichotic listening task measures at baseline and post-intervention by study condition

Outcome	Monitor + Accept (Pre and Post N=51)			Monitor Only (Pre N=51; Post N=46)			No Treatment Control (Pre N=26;Post N=28)			Time x Condition Difference
Outcome	Pre	Post	d	Pre	Post	d	Pre	Post	d	Time x Condition Difference

Trait AC	2.43 (.06)	2.79 (.06)	.84	2.42 (.06)	2.69 (.06)	.64	2.40 (.08)	2.46 (.08)	.14	χ²(2)=9.69, p=.008
Momentary AC^a	4.41 (.11)	4.86 (.11)	.57	4.09 (.11)	4.53 (.11)	.57	3.97 (.15)	4.18 (.15)	.27	χ²(2)=7.99, p=.018
Task Performance	2.80 (.20)	2.94 (.20)	.10	2.85 (.20)	3.11 (.21)	.18	2.28 (.26)	2.58 (.27)	.22	χ²(2)=0.48, p=.787
Task Distraction	36.24 (3.52)	26.72 (3.64)	.37	37.97 (3.56)	25.04 (3.88)	.50	34.38 (4.73)	39.78 (5.10)	.21	χ²(2)=7.53, p=.023

Note: Data are reported as means (SE) adjusted for observation number within day (coded 0–4). AC = attentional control. d = Cohen’s d effect size estimate.

There were not significant between-group differences in trait attentional control, task performance, or task distraction at baseline.

There were small between-group differences in momentary attentional control at baseline (χ2(2)=7.63, p=.022).
