Following the procedures outlined previously, the homogeneity of all 300 effect sizes presented in Table 3 was then assessed using the Q-statistic. Using a conservative alpha of p < .001, there were a total of 110 effect sizes (from the total of 300) for which the assumption of homogeneity was rejected. In other words, the reported values for these particular relationships do not estimate a common effect size, but instead represent an average of discrepant values obtained within various studies. These values are underlined within Table 3. When the pattern of these violations was organized by personality disorder it became clear that these were largely confined to the relationships within a few select diagnoses. The obsessive-compulsive, histrionic, and avoidant diagnoses had 22, 19, and 16 effect sizes respectively, for which the assumption of homogeneity were rejected, while a majority of the personality disorder diagnoses had only a handful of effect sizes that were significantly heterogeneous (albeit, at times, they concerned key facets for a respective personality disorder).
