From: Sense of competence questionnaire among informal caregivers of older adults with dementia symptoms: A psychometric evaluation

We expected: Value outcome found Hypothesis accepted?*
Burden   
A moderate to strong negative association with measures of caregivers' burden. 1. Association with caregivers' burden:
r = -0.21, 95% Confidence Interval (CI): [-0.43, 0.01]; n = 82.
-
  2. Categories of burden:
-equal distances: 49.5 (SPPIC 0–3, n = 45), 48.6 (3–6, n = 25), to 46.7 (6–9, n = 12);
-equal observations: 49.9 (1, n = 21), 49.4 (2, n = 18), 49.6 (3, n = 23), 46.2 (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 = 0.24, 95% CI: [0.03, 0.46]; n = 88.
-
  2. Categories of mental quality of life:
-equal distances: 46.1 (MCS 0–33.3, n = 8), 48.3 (33.3–49.9, n = 27), to 50.0 (49.9–100.0, n = 53);
F = 1.535, p = 0.221;
-equal observations: 47.3 (1, n = 22), 48.2 (2, n = 22), 50.1 (3, n = 22), 50.8 (4, n = 22); F = 1.434, p = 0.239.
-
Depressive symptoms   
A moderate to strong negative association with depressive symptoms. 1. Association with caregivers' depressive symptoms:
r = -0.21, 95% CI: [-0.42, 0.004]; n = 88.
-
  2. Categories of depressive symptoms:
-dichotomised: 47.4 (CES-D ≥ 16.0, n = 18), 49.5 (CES-D < 16, n = 70),
student's t-test: p = 0.212.
-
Mastery   
A moderate to strong positive association with mastery. 1. Association with caregivers' mastery:
r = 0.19, 95% CI: [-0.02, 0.41]; n = 85.
-
  2. Categories of mastery:
-equal distances: 46.8 (mastery 16–21, n = 18), 49.3 (mastery 21–28, n = 45), to 50.7 (mastery 28–35, n = 21);
-equal observations: 47.2 (1, n = 23), 50.5 (2, n = 20), 48.3 (3, n = 20), 50.7 (4, n = 22).
