Table 5 Tested hypotheses on construct validity: Satisfaction with the care recipient

Burden

A moderate to strong negative association with measures of caregivers' burden.

1. Association with caregivers' burden:

r = -0.23, 95% CI: [-0.46, -0.02]; n = 82.

2. Categories of burden:

-equal distances: 30.4 (SPPIC 0–3, n = 45), 30.2 (3–6, n = 25), to 27.1(6–9, n = 12);

-equal observations: 30.7 (1, n = 21), 30.1 (2, n = 18), 30.7 (3, n = 23), 27.9 (4, n = 20).

Mental quality of life

A moderate to strong positive association with measures of caregivers' mental quality of life.

1. Association with caregivers' mental quality of life:

r = 0.16, 95% CI: [-0.05, 0.38]; n = 88

2. Categories of mental quality of life:

-equal distances: 29.4 (MCS 0–33.3, n = 8), 29.0 (33.3–49.9, n = 27), to 30.3 (49.9–100.0, n = 53);

-equal distances: 28.4 (1, n = 22), 30.3 (2, n = 22), 30.0 (3, n = 22), 30.7 (4, n = 22).

Depressive symptoms

A moderate to strong negative association with depressive symptoms.

1. Association with caregivers' depressive symptoms:

r = -0.05, 95% CI: [-0.26, 0.16]; n = 88.

2. Categories of depressive symptoms:

-dichotomised: 30.0 (CES-D ≥ 16.0, n = 18), 29.8 (CES-D < 16, n = 70),

student's t-test: p = 0.830.

Mastery

A moderate to strong positive association with mastery.

1. Association with caregivers' mastery:

r = 0.15, 95% CI: [-0.06, 0.37]; n = 85

2. Categories of mastery:

-equal distances: 28.9 (mastery 16–21, n = 18), 29.8 (mastery 21–28, n = 45), to 30.7 (mastery 28–35, n = 22);

-equal observations: 28.9 (1, n = 23), 30.2 (2, n = 20), 29.8 (3, n = 20), 30.7 (4, n = 22).
