Psychological contract breach and outcomes: Combining meta-analysis and structural equation models

prominent factor in the empirical research of organizational psychology, and has been used to predict a broad range of individual and organizational outcome variables. However, not all results are consistent, nor do they show relationships in the same direction, as there are important variations both in the size and in the sign of the relationships between PCB and the attitudes and behaviours of the people exposed to them. The number of empirical studies attempting to evaluate the existence of PCB has increased steadily during the last few years. Nevertheless, no quantitative review has been conducted to assess the strength and generalizability of these relationships. Our research attempts to fill this gap using meta-analytic techniques to summarize the relationships between PCB and important outcome variables. The absence of previous meta-analyses is not the only reason for concern. There is the additional issue of the overall evaluation of the effect size (ES) of PCB. This issue has not been dealt with in the literature. Moreover, based on the fruitful results of metaanalysis obtained in many research domains (Topa, Depolo, & Morales, 2007), it can be beneficial to use meta-analytic techniques and SEM (Structural equation modelling) in testing causal models, such as some authors suggested (Viswesvaran & Ones, 1995; Cheung & Chan, 2005).
