Design outcomes

Primary

MeasureTime frame
Overall number of app-opens throughout the intervention;Number of workshops or modules completed (score ranging from 0 to 12);Number of home practice activities started (score ranging from 0 to 10)

Secondary

MeasureTime frame
Overall time spent on the app throughout the intervention;Number of workshops or modules started scoring 0 - 12 ;Total number of ParentPoints (self-reported habit tracker) logged throughout the intervention;Child maltreatment (exploratory outcome, moderator) Four items adapted from the reduced version of the ISPCAN Child Abuse Screening Tool-Trial Parent Version (Meinck et al., 2018) will be used to assess child maltreatment. The tool asks caregivers to report the frequency of emotional abuse (2 items, e.g., “shout, scream or yell” and “insult or call names or stupid”) and physical abuse (2 items, “hitting, spanking or slapping with a hand or with an object like a stick or belt” and “discipline with a push or grab”) over the past month using a scale of 0 to 8 or more times. Items sum to create a score for each subscale as well as a total child maltreatment score. ;Positive parenting (exploratory outcome, moderator) Five items from the Alabama Parenting Questionnaire (Essau et al., 2006) will be used to assess positive parenting. Caregivers will be asked to give a frequency score of their behaviours towards their adolescents in the past month on a scale of 0 to 8 or more times. The tool measures positive parenting (1 item, “how many times have you praised your teen?”), involved parenting (1 item, “get involved in activities that your teen likes”, and parental supervision (3 items, e.g., “stay out in the evening past the time they are supposed to be home”). Items sum to create a total positive parenting score as well as a score for the parental supervision subscale. ;Parental communication about sexual risk prevention (exploratory outcome, moderator) Three items adapted from the Parent Teen Sexual Risk Communication Scale III (Hutchinson, 2007) will be used to assess adolescent sexual risk behaviour and caregiver communication about sexual risk prevention.
