Abstract

Objectives
Patient identified need is key to delivering holistic, supportive, person-centred care but we lack tools enabling patients to express what they need to manage life with a long-term condition. The Support Needs Approach for Patients (SNAP) tool was developed to enable patients with advanced Chronic Obstructive Pulmonary Disease (COPD) identify and express their unmet support needs to healthcare professionals (HCPs), but its validity is unknown. This study aimed to establish face, content and criterion validity of the SNAP tool.
Design
Two-stage mixed-method study involving patients with advanced (COPD), and their carers. Stage 1: Face and content validity assessed though focus groups involving patients and carers considering appropriateness, relevance and completeness of the SNAP tool. Data were analysed using conventional content analysis. Stage 2: Content and criterion validity assessed in a postal survey through patient self-completion of the SNAP tool and disease impact measures (Chronic Respiratory Questionnaire, COPD Assessment Test, and Hospital Anxiety and Depression Scale). Content validity assessed using summary statistics; criterion validity via correlations between tool items and impact measures.
Settings and participants
Two hundred and forty patients and carers participated. Stage 1 patient and carer participants were recruited from two primary care practices and Stage 2 patients from twenty-eight practices. Participating practices located in the East of England were recruited via the NIHR Clinical Research Network: Eastern.
Results
Patients and carers found the tool patient-friendly and comprehensive, with potential clinical utility. No tool items were redundant. Clear correlations were found between tool items and the majority of items in the impact measures.
Conclusions
The SNAP tool has good face, content and criterion validity. It has potential to support the delivery of holistic, supportive, person-centred care by enabling patients to identify and express their unmet support needs to HCPs.
