Abstract
- Background: National Health Service use the Community Mental Health Service User Questionnaire (NHS-CMH) to assess care quality. However, its reliability and internal validity is uncertain.<br />Aims: To test the NHS-CMH structure, reliability and item-level characteristics.<br />Methods: We used data from 11,373 participants who answered the 2017 NHS-CMH survey. First, we estimated the NHS-CMH structure using Exploratory Factor Analysis (EFA) in half of the dataset. Second, we tested the best EFA-derived model with Confirmatory Factor Analysis (CFA). We tested the internal validity, construct reliability (omega - ω ), explained common variance of each factor (ECV), and item thresholds.<br />Results: EFA suggested a 4-factor solution. The structure derived from the EFA was confirmed, demonstrating good reliability for the four correlated dimensions: "Relationship with Staff" ( ω = 0.952, ECV = 40.1%), "Organizing Care" ( ω = 0.855, ECV = 21.4%), "Medication and Treatments" ( ω = 0.837, ECV = 13.3%), and "Support and Well-being" ( ω = 0.928, ECV = 25.3%). A second-order model with a high-order domain of "Quality of Care" is also supported.<br />Conclusions: The NHS-CMH can be used to reliably assess four user-informed dimensions of mental health care quality. This model offers an alternative for its current use (item-level and untested sum scores analysis).
