Study protocol.

Criteria	Purpose	Strategy	Additional Rigour
Credibility	To establish confidence that participants’ accounts were true/credible	To recruit from support groups To use tools to screen for exposure to parental alienating behaviours	Investigators spent time liaising with potential participants before the study to ensure suitability Investigators had a good theoretical understanding of parental alienation before beginning interviews Regular debriefings were held with additional members of the lab team to discuss issues related to data collection
Dependability	To ensure findings made in the current study are repeatable	NVivo used to capture data analysis Detailed description of the method	A detailed track record of the data collection was kept outlining each step of the process Each stage of analysis was logged using NVivo in a stepwise fashion for ease of reference
Confirmability	To establish confidence that similar results would be confirmed by other researchers	To reflect on own biases and assumptions Triangulation of data	Frequent reflective supervision/correspondence with head investigator Data were triangulated from principles/theory, methodology, and interviews
Transferability	The degree to which results can be transferred to other settings	Data saturation	Data saturation was achieved when no new information was able to be obtained from transcripts after multiple coding sessions from 2 investigators
