As it turned out, several of the people interviewed had applied an implicit research methodology that greatly resembled Schön's model; an operationalization and mapping of this model onto the steps of a general research methodology4 is shown in Table 1.
Phase 1: Intervention modelling and operationalization through a qualitative, socioconstructivist study using theoretical sampling with 10 in-depth interviews to patients with knee osteoarthritis and 4 discussion groups of 8 12 primary care professionals, evaluated using a sociological discourse analysis.
This approach will result in twelve final models (4 operationalizations of the predictor × 3 main outcomes).
Much has been said about what constitutes EI, as is apparent from the diversity of EI models and operationalizations.
However, there are several other models and operationalizations available covering other aspects of work-related stress, such as the effort-reward imbalance, job insecurity, and organisational injustice, which is not covered in the present study.
There remains the question of whether elevated somatic complaints, higher sensitivity and lower pain tolerance in correlation to alexithymia could generate a model or an operationalization of the mechanisms through which migraine-related information is processed.
The model was capable of operationalization of data as an abstract construct referring to other hidden and integrative indications.
Categorizing this RFEI into a 3-level ordinal variable and applying this variable in the respective logistic regression model showed that this alternative operationalization of the retail food environment was also not predictive for obesity.
For example, its weak operationalization has frequently been noted [ 9].
To further develop qualitative research approaches, i.e., conceptual and empirical studies that lay the foundation for the operationalization in formal models as well as for the validation of developed formal models, recommendation (5) addresses the need to broaden research foci to a wider variety of industries.
