Exploratory factor analysis of OCP items revealed four factors explaining about 75% of the variance, and supported the structure of the Competing Values Framework.
Factors were labeled Group, Hierarchical, Rational and Developmental. Multilevel regression analysis suggested that the four culture types varied significantly between workplaces, and correlated with mental health and well-being outcomes.
We then test the construct validity of the 26-item OCP questionnaire instrument with a sample of 1,164 employees nested in 30 workplaces.
Next, we test associations between the dimensions of the OCP survey instrument and employee psychological distress, depression, emotional exhaustion and well-being.
Some types of organizational culture therefore appear to be more relevant than others depending upon the phenomenon being addressed by the research.
Just as some culture types appear to be well suited to the study of organizational innovations , or other outcomes of interest, other culture types might more applicable to the study of occupational health.
The Group culture type best distinguished between workplaces and had the strongest associations with the outcomes.
This study provides strong support for the use of the OCP scale for measuring organizational culture in population-based occupational health research in a way that is consistent with the Competing Values Framework.
A pattern of shared basic assumptions that the group learned as it solved its problems of external adaptation and internal integration, that has worked well enough to be considered valid and, therefore, to be taught to new members as the correct way you perceive, think, and feel in relation to those problems.This theory-based measurement approach, which is clearly lacking in the analysis of OCP items , is intended to contribute to the advancement of occupational health research involving multilevel, population-based investigations that consider the meaningful facets of the organizational context in which stress occurs.The Organizational Culture Profile (OCP) proposed by O’Reilly et al.In the context of complex multilevel occupational health research, other approaches that involve collecting qualitative data  or a multi-method conceptualization of organizational culture are considered difficult to apply.We will argue further on that a meritorious alternative for such research may be found either in the 26-item Organizational Culture Profile (OCP) survey instrument  or in a shorter form derived from this instrument.
