Hypothesis

How different scoring methods affect the measurement of subjective age across the adult life-course.

Conclusion

Chronological age significantly influences how old individuals feel, with younger participants feeling older than their actual age, a trend that reverses as age increases.

Supporting Evidence

  • Younger participants felt older than their chronological age.
  • This difference decreased and reversed with increasing age.
  • Felt discrepancies were largest at both extremes of the age sample.
  • Chronological age is a significant predictor for all scoring methods.

Takeaway

This study looked at how people of different ages feel about their age and found that younger people often feel older than they are, but older people feel younger.

Methodology

Participants aged 18 to 84 reported their subjective age over two weeks using various scoring methods.

Limitations

The study's design and scoring methods may influence interpretations of subjective age.

Participant Demographics

Participants aged 18 to 84, with a mean age of 54.50 and 60.95% female.
