This cross-sectional study was conducted in 2 countries Hong Kong and Brazil with nurses working in hospitals who responded to a self-administered questionnaire with demographic data and responses to a 20-item Compliance with Standard Precautions Scale.
The final COSI consists of 28 items in 4 domains (Interference in Daily Life: Home 5 items, Work 4 items; Psychological Health: 10 items; Injection Burden: 4 items; Compliance Worry: 5 items).
The questionnaire contained 56 items assessing the following six concepts: a/Patient characteristics, (18 items), b/Treatment characteristics (6 items), c/Patient-clinician relationship (12 items), d/Patient treatment experience (8 items), e/Patient-treatment interaction (8 items), and f/Patient compliance (4 items).
For the secondary evaluation, omitting nonmodifiable barriers, the ability of sites to successfully implement their action items varied from achieving a 4 or 5 progress rank for one of the six action items (17% compliance) at Site 3, to six out of seven action items (86% compliance) at Sites 1 and 5.
Consequently, we checked the items for compliance with the Rasch model and excluded divergent items.
Safety measures: items regarding (compliance of) safety protocols, and 9.
The questionnaire also contains items concerning compliance with medication and diet.
Thus, items on compliance, distribution of co-interventions and timing of outcome assessment are given the same weight as concealment of allocation, which, along with blinding, has been documented as the most important safeguard against bias [ 3, 4].
Six dimensions were then selected and named, based on the content of the items: concern about treatment (five items), concern about disease (two items), satisfaction with patient-clinician relationship (five items), positive beliefs (three items), treatment convenience (three items) and self-declared compliance (three items).
The new structure obtained with the PCA included six dimensions: concern about treatment (five items); concern about disease (two items); satisfaction with patient-clinician relationship (five items); positive beliefs (three items); treatment convenience (three items); and self-declared compliance (three items).
