Description: The major purpose of this study was to establish construct validity of the sleep pattern disturbance which was one of the nursing diagnoses approved for clinical testing by the North American Nursing Diagnosis Association. The defining characteristics of the sleep pattern disturbance was expanded to 39 items which were identified from primary sources of literature and by master's prepared clinical experts.

A total of 1,087 nurses were systematically randomly selected for a mail survey from medical-surgical nurses in the state of Illinois and 521 nurses rated each of 39 defining characteristics of sleep pattern disturbance on a 5-point rating scale in light of their overall experience with patients having sleep pattern disturbance.

Thirty three defining characteristics were found to have a high coefficient alpha (.90) and a significant average inter-item correlation (.21) indicating acceptable reliability. Construct validity of the total scale was established by the homogeneity of items and principal factor analysis. The 3 factors which described the 3 subconcepts of sleep pattern disturbance were identified and labelled as behavioral manifestations, cognitive/perceptual responses, and motor-sensory manifestations. Based on the criteria of eigenvalue > 1.0, significant factor loading > .40, corrected item-total correlation > .30 and the overall median score (3.02) of the total scale, 12 essential defining characteristics were selected and their reliability and construct validity were established in this study. These 12 essential defining characteristics can be used as a valid and reliable clinical guideline for diagnosing the sleep pattern disturbance of the adult medical-surgical patients by nurses in clinical settings.
