Adult lesbians are insufficiently active to achieve health benefits. An 8-week pilot intervention targeting coping skills to overcome barriers, was designed to increase moderate physical activity (MPA) among adult lesbians. Sixteen lesbians aged 29 to 55 years (experimental condition [EC] [n = 10]; control condition [CC] [n = 6] completed measures at baseline and end-program. Mixed repeated-measures ANOVAs used to examine between-group differences in average daily: (a) MPA, (b) task self-efficacy (TSE), and (c) self-regulatory efficacy (SRE) from baseline to end-program, were not significant. Two data trends with moderate effect sizes were identified: (1) the EC maintained 24 minutes/d of MPA (P = .10; d = .43); and (2) TSE was maintained among the EC but decreased for the CC (P = .09; d=.44). Only a small effect size was found (P = .56; d = .16) for SRE. The intervention appears to stem declines in MPA and task-related efficacy beliefs.
