2.2. Data Collection Tool and Validation

The MISSCARE questionnaire was adapted for data collection in this study with permission from the original authors—Kalisch B.J. and Williams R. (2009) [15]—and reviewed by three experts before distributing. The items in the first part were divided into six sections, with each one containing several question items (assessment: 8 items; intervention: 13 items; and planning: 3 items) using the five-point Likert scale (never missed, rarely missed, occasionally missed, frequently missed, always missed) and using four degrees of the reason for missed nursing care (with respect to communication (8 items), material resources (3 items), and labour resources (3 items)): not a reason for missed care, minor reason, moderate reason, and significant reason.

A pilot study was conducted with a sample of 16 nurses to confirm the validity of the test using Cronbach’s alpha. The Cronbach’s alpha coefficients for the first and second sections were found to be 0.93 and 0.95, respectively.
