Abstract

OBJECTIVE:

To develop and pilot test a generic questionnaire to measure continuity of care from the patient's perspective across primary and secondary care settings.

STUDY DESIGN AND SETTING:

We developed the Nijmegen Continuity Questionnaire (NCQ) based on a systematic literature review and analysis of 30 patient interviews. The questionnaire consisted of 16 items about the patient-provider relationship to be answered for five different care providers and 14 items each on the collaboration between four groups of care providers. The questionnaire was distributed among patients with a chronic disease recruited from general practice. We used principal component analysis (PCA) to identify subscales. We refined the factors by excluding several items, for example, items with a high missing rate.

RESULTS:

In total, 288 patients filled out the questionnaire (response rate, 72%). PCA yielded three subscales: "personal continuity: care provider knows me," "personal continuity: care provider shows commitment," and "team/cross-boundary continuity." Internal consistency of the subscales ranged from 0.82 to 0.89. Interscale correlations varied between 0.42 and 0.61.

CONCLUSION:

The NCQ shows to be a comprehensive, reliable, and valid instrument. Further testing of reliability, construct validity, and responsiveness is needed before the NCQ can be more widely implemented.
