Clinical Validation of the Nursing Diagnosis ‘Inadequate Health Self‐Efficacy’ in People With Hypertension

Abstract

AimsTo test the clinical validity of clinical indicators and causal relationships of aetiological factors of the new nursing diagnosis of inadequate health self‐efficacy in people with hypertension.BackgroundThe diagnosis of inadequate health self‐efficacy has both theoretical and content validity. However, a clinical validation study is needed to establish an appropriate framework for distinguishing individuals who manifest this unique human response.DesignThe study adopts a cross‐sectional clinical validation approach, adhering strictly to the STROBE guidelines throughout its design and implementation.MethodsNaturalistic sampling was used to identify 302 adults diagnosed with hypertension. Their data were subjected to latent class analysis, which facilitated the identification of a comprehensive set of clinical indicators that demonstrated better diagnostic accuracy and established posterior probabilities to guide the inference of inadequate health self‐efficacy. In addition, logistic regression analysis was used to assess the magnitude of the impact of aetiological factors.ResultsThe prevalence of inadequate health self‐efficacy was 76.61%. Among the 13 indicators examined, seven demonstrated notable sensitivity: ‘risk‐prone health behaviour’, ‘failure to take action that prevents health problems’, ‘inadequate self‐control’, ‘avoidance behaviours’, ‘negative health self‐perception’, ‘inadequate health‐related quality of life’ and ‘difficulty feeling good about adopting a healthy lifestyle’. Additionally, two indicators showed high specificity: ‘difficulty feeling good about adopting a healthy lifestyle’ and ‘inadequate adherence to treatment regimen’. Notably, 15 aetiological factors were identified as significantly associated with an increased risk of inadequate health self‐efficacy.ConclusionsA clinical framework consisting of eight clinical indicators and 15 aetiological factors was developed to characterise inadequate health self‐efficacy in individuals with hypertension.Relevance to PracticeClinical validation provides insight into the precision of clinical indicators and the magnitude of the effect of putative causal elements, thereby facilitating identification and tailored intervention for individuals with hypertension and inadequate health self‐efficacy.
