Description: This descriptive exploratory study was guided by a diagnostic reasoning framework in addressing the research questions: (1) What is the evidence to support the content validity of the nursing diagnosis altered level of consciousness? and (2) What is the evidence to support construct validity of the nursing diagnosis altered level of consciousness? Several subquestions were addressed in the study.

In Phase I, the content validity of defining characteristics and operational definitions for the nursing diagnosis altered level of consciousness was examined by a panel of content experts using a modified Delphi technique. The nursing diagnosis was divided into two diagnoses-altered level of consciousness: arousal and altered level of consciousness: content. There was support for content validity as evidenced by $\geq$70% agreement on the appropriateness and clarity of 28 and 24 defining characteristics and operational definitions for altered level of consciousness: arousal and altered level of consciousness: content, respectively.

In Phase II, 30 nurse subjects in a NICU examined the construct validity of the two nursing diagnoses using magnitude estimation scaling and the GALOCNAT. There were 7 critical defining characteristics, 14 important defining characteristics, and 8 clinical manifestations for altered level of consciousness: arousal. There was no statistically significant relationship between importance and frequency. The nurse subjects identified 6 critical defining characteristics, 12 important defining characteristics, and 6 clinical manifestations for altered level of consciousness: content. There was a statistically significant relationship between importance and frequency.

In Phase III, the construct validity of both diagnoses was examined by assessing 60 patients to determine if there was a difference in the frequency of occurrence of defining characteristics in patients with an altered level of consciousness: arousal and content when compared to patients without an altered level of consciousness: arousal and content. There were 13 defining characteristics that occurred with significantly greater frequency in patients with an altered level of consciousness: arousal and 17 defining characteristics that occurred with significantly greater frequency in patients with an altered level of consciousness: content. Future studies should focus on identifying nursing goals and interventions for altered level of consciousness: arousal and altered level of consciousness: content.
