Internal consistency was assessed with omega coefficients and composite reliability. Test\u2013retest reliability between baseline and 6\u2009months was estimated using the Intraclass Correlation Coefficient (ICC).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 275 informal caregivers of patients with IBD completed the CC\u2010SC\u2010CII. CFA supported the original three\u2010scale structure of the CC\u2010SC\u2010CII (maintenance, monitoring, management), with acceptable model fit after minor item\u2010level adjustments. Internal consistency ranged from 0.71 to 0.94 across subscales. ICCs ranged from 0.749 to 0.896, indicating good to excellent test\u2013retest reliability. All item\u2010total correlations exceeded 0.30. Positive correlations with caregiver self\u2010efficacy scores supported construct validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
