dc.description.abstract | Introduction: Successful implementation and embedding of new health care practices relies on co-ordinated, collective
behaviour of individuals working within the constraints of health care settings. Normalization Process Theory (NPT)
provides a theory of implementation that emphasises collective action in explaining, and shaping, the embedding of
new practices. To extend the practical utility of NPT for improving implementation success, an instrument (NoMAD)
was developed and validated.
Methods: Descriptive analysis and psychometric testing of an instrument developed by the authors, through an
iterative process that included item generation, consensus methods, item appraisal, and cognitive testing. A 46
item questionnaire was tested in 6 sites implementing health related interventions, using paper and online completion.
Participants were staff directly involved in working with the interventions. Descriptive analysis and consensus methods
were used to remove redundancy, reducing the final tool to 23 items. Data were subject to confirmatory factor analysis
which sought to confirm the theoretical structure within the sample.
Results: We obtained 831 completed questionnaires, an average response rate of 39% (range: 22–77%). Full
completion of items was 50% (n = 413). The confirmatory factor analysis showed the model achieved acceptable fit
(CFI = 0.95, TLI = 0.93, RMSEA = 0.08, SRMR = 0.03). Construct validity of the four theoretical constructs of NPT was
supported, and internal consistency (Cronbach’s alpha) were as follows: Coherence (4 items, α = 0.71); Collective
Action (7 items, α = 0.78); Cognitive Participation (4 items, α = 0.81); Reflexive Monitoring (5 items, α = 0.65). The
normalisation scale overall, was highly reliable (20 items, α = 0.89).
Conclusions: The NoMAD instrument has good face validity, construct validity and internal consistency, for assessing
staff perceptions of factors relevant to embedding interventions that change their work practices. Uses in evaluating
and guiding implementation are proposed. | |
