Concept analysis of anxiety.
ABSTRACT Anxiety, a nursing diagnosis that impacts clients in all settings and nurses throughout the profession, is clarified through the technique of concept analysis. Uses of the concept of anxiety in prominent theories of human behavior and in nursing are reviewed. Four critical attributes occurring in all cases of anxiety are identified--model cases, a related case, a contrary case, and an illegitimate case are presented. Antecedents to anxiety are identified. Consequences of anxiety are discussed. Empirical referents that demonstrate occurrence of the concept of anxiety are determined, classified, and related to critical attributes. This concept analysis provides an essential conceptual base for instrument development and clinical research on anxiety.

ABSTRACT: This study aims to validate the nursing diagnosis of anxiety among expert Brazilian nurses and clinicians using NANDA International defining characteristics and to compare the clinical judgments of the experts and the clinicians. A semistructured questionnaire was completed by a convenience sample of 120 nurses. NANDA International defining characteristics of the Brazilian Portuguese version were used. The analysis of the ratings was based on the framework of the Diagnostic Content Validation model. Brazilian nurses considered the anxiety definition established by NANDA International to be appropriate and experts' and clinicians' judgments were similar for both groups of nurses. The results showed that among the 71 characteristics of anxiety, 8 were identified as critical defining characteristics of anxiety (score >or= 0, 80) by the expert nurses. Brazilian nurses accepted the NANDA International definition for nursing diagnosis of anxiety although some defining characteristics might differ due to cultural differences. Future research could address the limitations of the study and examine validations by both the experts and the clinicians. The adequate preparation of undergraduate and postgraduate nurses in nursing diagnosis is important in improving the quality of care given to patients.International Journal of Nursing Terminologies and Classifications 07/2008; 19(3):102-10.

Article: A concept analysis of panic.[Show abstract] [Hide abstract]
ABSTRACT: Minimal attention has been focused on the concept of panic in the discipline of nursing. Hindering a greater understanding of panic is its lack of explication and development in nursing. To help remedy this situation, a concept analysis of panic was performed. The hybrid model of concept development was used, which consists of an initial theoretical phase, a fieldwork phase, and a final analytical phase. In the theoretical phase, after a cross-disciplinary literature search was done, existing definitions and measurement of the concept of panic were analyzed, and a working definition of panic was formulated. In the fieldwork phase, women experiencing postpartum panic disorder were interviewed to collect qualitative data for further analysis of panic. The final phase focused on comparing and contrasting the findings from the theoretical phase with the insights discovered from the fieldwork. Applicability of panic across nursing is addressed along with implications for nursing theory, practice, and research.Archives of Psychiatric Nursing 11/1996; 10(5):265-75.

ABSTRACT: ACCESSIBLE SUMMARY: • Evaluating outcomes of research and clinical interventions for patients with anxiety requires a valid instrument for measuring anxiety. • We evaluated the psychometric properties of the Chinese Mandarin version State-Trait Anxiety Inventory Y form (CMSTAI-Y) in Taiwanese outpatients with anxiety disorders. • The reliability and criterion validity of the CMSTAI-Y for measuring trait and state anxiety were supported in outpatients with anxiety disorders. • The CMSTAI-Y had a four-factor construct validity for measuring trait and state anxiety, as confirmed by adequate representation of the data. ABSTRACT: This study was conducted to develop the Chinese Mandarin State-Trait Anxiety Inventory Y form and to evaluate its psychometric properties among Taiwanese outpatients with anxiety disorders. A three-phase survey questionnaire was used to gather cross-sectional data. Non-hospitalized adults (n= 306) with anxiety disorders were recruited from mental health clinics in central Taiwan. Cronbach's alpha reliabilities for the state and trait anxiety subscales were 0.91 and 0.92, respectively. The 2-week test-retest reliabilities for the state and trait anxiety subscales were 0.76 and 0.91, respectively. Criterion validity of the scale was supported by its high correlations with the interview version of the Chinese Hamilton Anxiety Rating Scale (r= 0.69 for state and 0.74 for trait anxiety). Construct validity of the scale was confirmed by a four-factor structure, showing slightly adequate representation of the data. The scale was shown to be reliable and may be valid for measuring anxiety in Taiwanese adults with anxiety disorders.Journal of Psychiatric and Mental Health Nursing 07/2012; 20(6).
