A meta-analysis of the interrelationships between the modes in Roy's adaptation model

A meta-analysis of nine empirical studies based on Roy's adaptation model was conducted to determine the magnitudes of the interrelationships of the four modes: physiological, self-concept, role function, and interdependence. Small to medium effect sizes between each two modes do support the proposition of Roy's model that the four modes are interrelated. The only exception is the relationship between interdependence and physiological modes, as shown by the non-significant effect size of .04. The present study also discusses several limitations that should be considered when interpreting the findings of this meta-analysis. This study does provide a useful compilation of the Roy model's credible studies and proposes a direction for further research. The results indicate a need for further study to explore the relationship in all response modes to have a clearer understanding of the credibility of Roy's model.
