Urine control theory derived from Roy's conceptual framework.

The urine control theory, a middle range theory substructed from Roy's adaptation model, is presented to explicate the phenomenon of urine control. Urine in the bladder is identified as the focal stimulus, and the impact of the cognator subsystem in relation to urine control is described. The role of contextual stimuli related to mobility and the environment is also described. Relationships between concepts are explained and supported with individual case studies. The case findings are used to exemplify the interrelationships in the model. The urine control theory can be used by practitioners to inform practice and by researchers to guide research designs.

Instrument development: the Mental Health-Related Self-Care Agency Scale.

This article addresses the development and initial testing of an instrument to measure individual's capabilities to perform mental health related self-care. A two-step process of development and judgment (Lynn, 1986) was used to develop and evaluate this instrument's content validity. The development phase included explication of the content domains, item generation, and instrument formation. Evaluation of the content validity was addressed by an expert panel for theoretical and clinical relevance. These processes resulted in a 35 item, self-report questionnaire. A pilot study supported the Mental Health Self-Care Agency Scale as a reliable and valid instrument appropriate for theory-testing research.

Effects of Orem-based nursing intervention on nutritional self-care of myocardial infarction patients.

The purpose of the study was to investigate the effect of nursing care based on Orem's nursing theory on nutritional self-care of myocardial infarction patients. Self-efficacy was explored as a disposition which may motivate behavioral change. One hundred and four subjects were randomly assigned to treatment or control groups. The nursing intervention, which took place during the first 6 weeks following hospital discharge, was effective in supporting healthy low-fat eating behavior. Nursing care influenced patients' self-care agency but lacked impact on self-efficacy for healthy eating.

Self-care agency: conceptualizations and operationalizations.

This article traces the interactive process between theory and research as it has been used to clarify the concept of self-care agency, a key concept in Orem's model of nursing. Theoretical constructions of self-care agency that have emerged in the work of Orem and the Nursing Development Conference Group are reviewed. Operational measures of self-care agency are described, particularly with regard to their underlying theoretical formulations. Factorial structures for some self-care agency instruments are related to the components of self-care agency in Orem's most recent conceptualization. Dimensions of self-care agency that are consistently supported by research studies of this phenomenon are identified.

Long-term follow-up of duodenal ulcer patients.

The CURE peptic ulcer clinic started in April 1974. Patients (mostly veterans) with documented ulcer disease were interviewed regularly and inpatient hospitalizations were reviewed for follow-up periods of up to 6 years. Data from 245 male ulcer patients, 190 with duodenal ulcer alone and 55 with both documented duodenal ulcer (DU) and gastric ulcer (GU), were analyzed to assess the natural history of ulcer disease and factors predicting the severity of its course. Eleven percent of clinic patients had a complication (bleeding requiring a transfusion, perforation, or obstruction) during follow-up. Complication rates were about 2.7% per year for those with no prior complication, and about 5% per year for those with a prior complication. No patient variables or ulcer markers were related to the likelihood of a complication. Patients with both DU and GU were similar to patients with DU alone on many background variables, but the combined ulcer group had a significantly higher frequency of blood group nonsecretors, increased incidence of cigarette smoking, and greater frequency of complications or ulcer hospitalization prior to entry into the study and during follow-up. These factors, together with our failure to find differences in aggressive factors (acid output and PGI), suggests that DU + GU represents a different disease entity marked by additional defects in mucosal defense.(ABSTRACT TRUNCATED AT 250 WORDS)

Meckel diverticulum: radiologic demonstration by enteroclysis.

Thirteen patients with surgically confirmed Meckel diverticula encountered in a 30 month period are reported. Of 11 symptomatic patients, all had lower gastrointestinal bleeding, except one who had recurrent abdominal pain only. Two diverticula were incidental, coexisting with Crohn disease of the distal ileum. One of these had occasional diarrhea and hematochezia. The diagnosis was established preoperatively by enteroclysis in 11 of these cases. The enterographic demonstration of the mucosal triangular plateau or the triradiate fold pattern indicating the site of exit of the omphalomesenteric duct should lead to a diagnosis of Meckel diverticulum. Pitfalls in interpretation due to the pseudotriangular plateau appearance formed by superimposition of two intestinal loops and the pseudosaccule produced by the axial projection of a fixed loop of bowel and the differential diagnosis are discussed. Enteroclysis seems to be the most dependable method currently available for preoperative demonstration of Meckel diverticulum.
