Despite the prevalence of infidelity, there is relatively little research regarding the long-term effects on the children. Combining the views of transgenerational theory with the existing literature on infidelity as a family stressor and infidelity as a trauma, this project examines the potential lasting effects of parental infidelity on the adult child. Study participants included a small sample of adults over the age of 18 who were aware of parental infidelity in their family of origin. Through a series of regression analyses using a moderator model, the researchers found that higher negative self schemata and affect ratings related to the perception of the infidelity were associated with more conservative attitudes toward sex. Suggestions for future utilization of the proposed model and the clinical implications of the findings are also discussed.
