Change in FTP across adulthood has been treated as linear, with older adults showing more limited FTP. Studies I and 2 showed that a 2-factor model fit better, with focus on opportunities and focus on limitations as distinct dimensions. These dimensions changed differentially with age. In cross-sectional Study 3, focus on opportunities was higher in young adulthood than in early middle age but did not drop further in late middle age. Focus on limitations was the same in young adulthood and early middle age but was higher in late middle age. In longitudinal Study 4, focus on limitations increased from early to late middle age, and focus on opportunities was again maintained, rather than showing the decrease one would assume from a I-factor model of FTP. 收起
