“…This first phase is focused on the theoretical background of the construct for which an instrument is to be developed and involves an operational definition through the inclusion of representative items (21) . In our case, the researchers designed the instrument based on the theoretical constructs of Gordon's Functional Health Patterns, as well as comprehensive bibliography on initial nursing assessment (1,4,(7)(8)(9)(14)(15)17,19) . Thus, the following 12 categories are included: Physical assessment, Health perceptionmanagement, Nutritional-metabolic pattern, Elimination, Activity-exercise, Sleep-rest, Cognitive-perceptual pattern, Self-perception-self concept, Role-relationship, Sexuality-reproductive, Coping-stress tolerance and Value-belief.…”
