Models Testing Affective and Cognitive Mediators in the Relations between the Pain X Partnership Status Interaction and Physical Disability
| Dependent Variable: Physical Disability | Potential Mediators | |||
|---|---|---|---|---|
| Positive affect only | Catastrophizing only | Pain Coping Difficulty only | All Mediators | |
| Predictors | b (SE) | b (SE) | b (SE) | b (SE) |
| Between-subject | ||||
| Diagnosis: OA vs FM | 19.56 (3.83)*** | 19.12 (3.79)*** | 15.54 (3.43)*** | 16.80 (4.07)*** |
| Partnership group: UnP vs HighSat | 3.09 (4.58) | 2.86 (4.53) | 3.03 (4.09) | 3.49 (4.22) |
| Partnership group: LowSat vs HighSat | 2.88 (4.95) | 2.78 (4.91) | 2.67 (4.42) | 3.01 (4.56) |
| Within-subject | ||||
| ΔPain | 0.29 (0.04)*** | 0.28 (0.04)*** | 0.20 (0.05)*** | 0.15 (0.04)** |
| ΔPositive Affect | −12.06 (0.70)*** | - | - | −11.44 (0.70)*** |

| ΔPain Coping Difficulty | - | - | 7.68 (0.55)*** | 6.37 (0.57)*** |
| ΔPain x Partnership group: UnP vs HighSat | 0.12 (0.05)* | 0.13 (0.05)* | 0.10 (0.06) | 0.08 (0.05) |
| ΔPain x Partnership group: LowSat vs HighSat | 0.13 (0.06)* | 0.14 (0.06)* | 0.10 (0.06) | 0.09 (0.05) |
Note: OA=osteoarthritis; FM = fibromyalgia; UnP = unpartnered, HighSat = partnered,/high satisfaction, LowSat = partnered/low satisfaction.
Between-subject dfs range from 243–245. Within-subject dfs range from 5424–5542.
