The purpose of this study was to determine the relationship between exposure to Parental Alienation (PA) at different developmental time periods and psychological maltreatment. Three hundred and sixty‐one adults in Chieti, Italy completed an anonymous and confidential paper and pencil survey regarding their childhood exposure to twenty PA behaviours across three developmental time periods as well as a measure of psychological maltreatment by each parent. Results revealed that exposure to PA at each time period was significantly associated with psychological maltreatment. Moreover, the number of time periods of exposure to PA (from 0 to 3) was associated with psychological maltreatment. This was true for PA by mothers and PA by fathers. Implications for policy and practice are discussed.
