[i] Note. Total time is measured in hours per week, EE = Energy expenditure (kcal per week), vigorous and walking index are measured in units per month, moving index is measured in hours per day. Subjective age is the proportional discrepancy age as a percentage with more negative values equating to a younger perceived felt age. Physical activity includes sport, exercise and physically active recreation activities.

Table 2
Subsamples, Subjective Age and Affectivity Scores for Affectivity Groups.
| Subsample n (%) | Subjective age M (SD) | Affectivity score M (SD) | ||
|---|---|---|---|---|
| Affectivity Groups | Pa | Na | ||
| PA ascendency | 17 (50) | –33 (16) | 44.1 (2.5) | 12.7 (1.8) |
| PA-NA convergence | 7 (21) | –24 (16) | 40.1 (2.9) | 14.9 (2.1) |
| NA ascendency | 10 (29) | –16 (15) | 35.3 (5.5) | 19.3 (3.4) |
[i] Note. PA = Positive Affectivity, NA = Negative Affectivity. Subsamples were derived from the comparison of standardised scores for PANAS positive and negative affectivity where PA ascendency includes participants with a PA score >0.5 SD above NA, PA-NA convergence includes participants with <0.5 SD between their PA and NA scores and NA ascendency includes participants with a PA score >0.5 SD below their NA score. Affectivity scores for each new group were derived from PANAS. Subjective age is the proportional discrepancy age as a percentage with more negative values equating to a younger perceived felt age.

[i] Note. CI = confidence interval; LL = lower limit; UL = upper limit. In Model 1, we entered subjective age followed by positive and negative affectivity as separate predictor variables. In Model 2, we entered subjective age followed by the combined affectivity profiles of PA ascendency, PA-NA convergence and NA ascendency. In Model 2, the dummy coded reference variable is NA ascendency. ΔR2 = change in R2.
