The residence arrangement has a proven impact on how children grow up after separation/divorce. See attached .pptx. So the different residence arrangements should be part of your data.
Even more important are the levels of parental conflicts, or rather how much the child sees/hears/feels/experiences them.
Will you include these aspects in your data gathering?
Your questions and comments are welcome.
