O’Leary Porter Scale Mean (S.D.) Scores in Treatment and Community Samples

Sample	Baseline	6-months	12-months
Community (n=78)	28.3 (SD=6)	28.6 (SD=5.6)	29.7 (SD=5.3)
Treatment (n=67)	22.6 (SD=6.2)^a	24.6 (SD=6.3)^b	25.3 (SD=6.3)^b
Treatment Subset who Remitted (n=20)	24.0 (SD=6.8)	26.9 (SD=5.4)	26.4 (SD=6.4)
Treatment subset Non-Remitted (n=43)	22.0 (SD=5.8)	23.7 (SD=5.6)	24.2 (SD=6.0)

Note. A lower score on the O’Leary Porter Scale reflects greater conflict exposure.

The treatment sample had significantly greater conflict exposure than the community sample at the baseline assessment.

This score in the treatment sample showed significant decrease in conflict exposure from the baseline assessment.
