“…The SAS was developed by the investigator team, drawing primarily upon standardized scales and measures used in addictions research and related sub elds that have solid psychometric properties. The SAS elicits information from participants along several dimensions covering a wide range of participant behavior metrics and social psychological concepts important for addiction research, including criminal justice involvement, additional adverse childhood experiences (ACEs) from an expanded ACEs instrument, 30 social support, 31 maternal attachment (antenatal 32 and postnatal 33 ), mental health (PTSD 34 and psychological distress 35 ), self-esteem 36 and self-e cacy, 37 addiction beliefs, 38, 39 parenting practices, 40 and parent/child experiences 41 and child development. 42 These measures allow us to examine both predictors of success, as well as additional secondary outcomes stemming from the intervention.…”
