This scoping review has highlighted how the imprisonment of a parent negatively affects their children's emotional and mental health. Factors negatively impacting children's emotional and mental health are interrelated and complex. Further research is required, including differences between paternal and maternal incarceration; impact of gender and age of child; poverty as an ACE and prison exacerbating this; and effects of ethnicity and race. An important policy direction is in developing an effective way of capturing the parental status of a prisoner to ensure that the child and family receive needed support.
