[Family intervention according to Roy. Planning, execution and evaluation].

Last month, the author presented the first two steps necessary in the development of a nursing care plan. This care plan utilized Sister Callista Roy's conceptual model and was designed to evaluate the family system. The readers became familiar with the Joly family, whose family system was evaluated (this included Diane and Jessie). Analysis of the collected data identified two nursing diagnoses and the author explained the way that nursing diagnosis is derived. The first identified nursing diagnosis revealed a threat to the beneficiary, the second diagnosis revealed a threat to the family system. This second article is devoted to the three other steps involved in the development of a nursing care plan that will assist the nurse in developing a systematic strategy in caring for this type of family. The planning step consists of the identification of objectives for care. These objectives must be specific, measurable and realistic as well as able to answer the question: "What changes are intended for this family?" Suggestions are offered for objective development. Once the objectives are finalized, the nurse chooses pertinent and realistic interventions that permit her/him, as well as Diane, to attain the identified objectives. The nurse's interventions are centred around stimuli that are increased, decreased or maintained by the goal of modifying or reinforcing observed behaviors. In the care plan example developed for the Joly family, the identified interventions are not all inclusive and serve as suggestions. During the course of the interventions the nurse must constantly readjust and adapt the interventions to fit with changing needs.(ABSTRACT TRUNCATED AT 250 WORDS)
