Validity in qualitative research.

Much contemporary dialogue has centered on the difficulty of establishing validity criteria in qualitative research. Developing validity standards in qualitative research is challenging because of the necessity to incorporate rigor and subjectivity as well as creativity into the scientific process. This article explores the extant issues related to the science and art of qualitative research and proposes a synthesis of contemporary viewpoints. A distinction between primary and secondary validity criteria in qualitative research is made with credibility, authenticity, criticality, and integrity identified as primary validity criteria and explicitness, vividness, creativity, thoroughness, congruence, and sensitivity identified as secondary validity criteria.

Implantable cardioverter defibrillators: physical and psychosocial outcomes.

BACKGROUND: The long-term outcomes of living with an implantable cardioverter defibrillator are an important consideration in recovery. However, little is known about physical and psychosocial outcomes beyond 1 year after implantation. OBJECTIVE: To describe the long-term physical and psychosocial adaptation of persons who have had an implantable cardioverter defibrillator for approximately 2 years or more. METHODS: This nonexperimental cross-sectional study used telephone interviews to ascertain the responses of 80 recipients of implantable cardioverter defibrillators to physical and psychosocial questionnaires to explore the long-term outcomes of living with the devices. Subjects eligible for inclusion were selected from the files of an arrhythmia clinic. RESULTS: Hierarchical regression analysis showed that subjects who are not emotional are likely to be more physically active, especially if they are young and male, and that subjects who tend to be emotional are likely to be psychologically distressed and have poorer social and domestic adaptation. Furthermore, use of emotions was a positive predictor of psychological distress and poor social and domestic adaptation. Subjects reported the use of both emotion- and problem-focused coping. Subjects' scores on physical and psychosocial functioning were comparable to scores reported in the literature for patients who have had myocardial infarction or dysrhythmia. CONCLUSIONS: Emotional responses to distress were predictive of little physical activity and psychological distress. Furthermore, young recipients of implantable cardioverter defibrillators and men were predicted to be physically active. Persons who have had an implantable cardioverter defibrillator for approximately 2 years or more can anticipate that their physical and psychosocial functioning will be similar to that of patients who have myocardial infarction or dysrhythmia.

The efficacy of relaxation response interventions with adult patients: a review of the literature.

The relaxation response is an integrated psycho-physiologic response originating in the hypothalamus that leads to a generalized decrease in arousal of the central nervous system. As such it is the physiologic antithesis of the stress response. This hypometabolic state is the foundation of many nursing interventions. Relaxation interventions have been taught for centuries. They include many theoretic and philosophic traditions and an array of specific strategies. The possible outcomes using relaxation response strategies in nursing practice are numerous and enable the patient to use the body's own innate mechanisms for health and healing. Thirty-seven studies of the efficacy of relaxation response interventions with adult patients are reviewed. Although numerous patient populations are addressed by the studies, some of which have methodologic problems, consistencies in the results suggest the effectiveness of the relaxation response in reducing hypertension, insomnia, anxiety, pain, and medication use across multiple populations, diagnostic categories, and settings. Recommendations for the use of relaxation responses in varied clinical settings are included.

The mind-body connection: the psychophysiology of many traditional nursing interventions.

The bidirectional relationship between mind and body and the concept that psychological processes can produce attendant physiologic changes are explored in this article. The mind-body connection provides a framework for exploring a psychophysiologic explanation for the therapeutic properties of some traditional nursing interventions to potentiate health and healing. This model allows nurses to move from tradition-based practice to knowledge-based practice. CNSs provide direct patient care, consult with staff nurses, influence systems of care, and engage in outcome research. This mind-body paradigm provides a model for practice and a framework for quantifying outcomes.

Relaxation response in femoral angiography.

Immediately before they underwent femoral angiography, 45 patients were given one of three types of audiotapes: a relaxation response tape recorded for this study, a tape of contemporary instrumental music, or a blank tape. All patients were instructed to listen to their audiotape during the entire angiographic procedure. Each audiotape was played through earphones. Radiologists were not told the group assignment or tape contents. The patients given the audiotape with instructions to elicit the relaxation response (n = 15) experienced significantly less anxiety (P less than .05) and pain (P less than .001) during the procedure, were observed by radiology nurses to exhibit significantly less pain (P less than .001) and anxiety (P less than .001), and requested significantly less fentanyl citrate (P less than .01) and diazepam (P less than .01) than patients given either the music (n = 14) or the blank (n = 16) control audiotapes. Elicitation of the relaxation response is a simple, inexpensive, efficacious, and practical method to reduce pain, anxiety, and medication during femoral angiography and may be useful in other invasive procedures.

Conceptual models used in clinical practice.

Nurses' difficulties in articulation of conceptual models may be due to several factors--not the least of which are the existence of discrete theories for each area of nursing specialization, dissociation in curricula of theory from practice, a holistic conceptual framework that may be inadequately defined at the process level, and an impulse toward idealism on the part of the nurses themselves. These observations challenge both the theorists and the practitioners of modern nursing to describe more clearly the definition of quality for the science and art of nursing. Nurses are beginning to grasp the idea of holism. It is not the summation of parts to make a whole. Holism is the identification of life patterns, which are reflective of the whole. Nurses in practice and research are starting to create methods of inquiry that portray the wholeness of the autonomous person in continual, dynamic change and exchange with a changing universe. These initial explorations are leading to the evolution of the concepts of person, environment, and health into a distinctive theoretical base for nursing practice. In practice, research, and education, nurses must be committed to excellent, current descriptions of these human life patterns.

Anxiety is a good indicator for somatic symptom reduction through behavioral medicine intervention in a mind/body medicine clinic.

BACKGROUND: This study examined the effect of anxiety on symptom reduction through a behavioral medicine intervention in a Mind/Body Medicine Clinic. METHOD: Participants were 1,312 outpatients attending a 10-week behavioral medicine intervention which included training in the relaxation response, cognitive restructuring, exercise and nutrition. All of the patients had physical symptoms and were referred to the clinic by their physician. The Medical Symptom Checklist (12 major symptoms), Symptom Checklist 90 Revised (SCL-90R), Stress Perception Scale and the Health-Promoting Lifestyle Profile were administered before and after the program. RESULTS: Of the sample, 1,012 patients completed the program, and 911 completed the posttreatment assessment. Self-reported frequency of medical symptoms, degree of discomfort and interference with daily activities were significantly reduced as a result of the program. Anxiety and other psychological distress as measured by the SCL-90R and stress perception scales also showed significant reductions. Furthermore, health-promoting lifestyle functioning significantly improved. High levels of pretreatment anxiety predicted a decrease in the total number of medical symptoms endorsed. CONCLUSIONS: Behavioral medicine interventions are effective in reducing medical symptoms coinciding with improvement in anxiety. High anxiety at program entry may predict better outcome.

The content, integrity, and efficacy of a nurse coaching intervention in type 2 diabetes.

PURPOSE: The purpose of this study was to systematically evaluate the content, integrity, and efficacy of a nurse coaching intervention provided after diabetes education that focused on dietary and exercise lifestyle change in persons with type 2 diabetes. METHODS: A multimethod design incorporated an interpretive approach to examine the content and integrity of the intervention and a multiple-baseline, single-subject method to determine the preliminary efficacy of the intervention. RESULTS: The primary strategies of the nurse coaching intervention consisted of facilitating lifestyle change through educational reinforcement, psychosocial support, and motivational guidance. Aggregate quantitative outcomes revealed a modest increase in health-promoting behaviors and a decrease in fasting blood glucose, indicating a trend toward physiologic adaptation. Participants demonstrated a significant increase in integration reflective of psychosocial adaptation. CONCLUSIONS: Providing individualized nursing care after diabetes education may improve health outcomes and the quality of life of persons newly diagnosed with type 2 diabetes. This multimethod design is a cost-effective approach for preliminary evaluation of complex and/or novel interventions.
