Diagnoses of Chronic Health Conditions and Change in Subjective Age: The Moderating Role of Chronological Age.

According to Social and Temporal Comparison theories, people compare themselves to their age peers and earlier selves. Given expectations for better health at younger chronological ages, being diagnosed with chronic health conditions may have a stronger association with subjective age among middle-aged persons as compared to older persons. The findings suggest that subjective age may be used as a screening tool to predict how chronic disease diagnosis may influence peoples' sense of self, which in turn shapes future health.
