Table 2.
Factor loading derived by reduced rank regression: using pre-SD mobility and social support items.
| Mobility Items | Factor Loading | Social Support Items | Factor Loading |
|---|---|---|---|
| Walking 200–300 m | 0.44 | Satisfaction with care from significant others | −0.57 |
| Climbing up 2–3 floors | 0.43 | Willingness of significant others to care for you | −0.54 |
| Squatting | 0.43 | Willingness of significant others to talk with you | −0.40 |
| Grasping with the fingers | 0.42 | Willingness of significant others to ask your opinion | −0.38 |
| Carrying 11 kg weight | 0.37 | Significant others’ complaints to you | −0.27 |
| Raising the arms up | 0.35 | -- |
SD: Spouse Death; Factor loadings with absolute value ≥0.2 are shown in bold; higher RRR score in mobility means worse mobility function; higher RRR score in social support means higher level of social support.
