The PS is a 30-item questionnaire designed to assess parentification, defined as the extent to which children are or have been used within their families of origin in roles usually assumed by parents.
The CTQ was designed to assess two primary aspects of timing as it relates to having a child: (1) the important of being ready for a child in terms of personal and professional stages in life and (2) how long respondents believe it will take until they are ready to have their next child.
