Personal mastery and lower body mobility in community-dwelling older persons: the Invecchiare in Chianti study.
OBJECTIVES To test the hypothesis that , in older persons , sense of personal mastery , defined as the extent to which one regards one 's life chance as being under one 's own control , predicts change in lower extremity performance during a 6-year follow-up . DESIGN Prospect i ve cohort study . SETTING Community based . PARTICIPANTS Six hundred twenty-six participants aged 65 and older . MEASUREMENTS  Personal mastery  was assessed at baseline using  Pearlin 's mastery scale . Lower extremity performance was measured at baseline and at 6-year follow-up using the Short Physical Performance Battery ( SPPB ) of lower extremity function . RESULTS Higher sense of mastery was associated with a significantly less-steep decline in lower extremity performance . Participants in the two lowest quartiles of personal mastery had , respectively , a 2.6 ( 95 % confidence interval (CI)=1.4 - 5.1 , P=.01 ) and 3.2 ( 95 % CI=1.6 - 6.6 , P=.002 ) higher risk of experiencing a substantial decline ( > or =3 points ) in SPPB scores after 6 years as those in the highest quartile . CONCLUSIONS Older individuals with poor sense of personal mastery are at high risk of accelerated lower extremity physical function decline . Whether interventions aim ed at improving personal mastery may prevent disability remains unknown
