Description of intervention(s) / exposure
Participating families will receive a modified version of Parent-Child Interaction Therapy (PCIT), adapted to meet the needs of children aged 12 to 24 months with emerging disruptive behaviour.

PCIT is a clinic-based protocol, which draws on real-time, wireless technology to provide in-vivo coaching of parent-child interactions by a therapist observing the parent-child dyad from behind a one-way mirror. Due to the developmental needs of children 12-24 months old, the adapted PCIT intervention under investigation includes the Child-Directed Interaction phase of PCIT (CDI) only. During sessions, parents are coached in traditional play therapy skills, including following the child’s lead and engaging in warm/affectionate and emotionally responsive parenting. Parents are taught to consistently attend to and reinforce positive child behaviours via "do" skills, including praise, descriptions of child behaviour, reflections of appropriate child speech, imitations of appropriate child behaviour, and expressing warm and affectionate behaviours towards the child (e.g., positive touch, increased eye contact), while simultaneously withdrawing their attention from negative, inappropriate behaviours. The overall purpose of applying these skills is to improve the quality of the parent-child relationship, which help promote changes in behaviour.

The first intervention session is a Teach session during which parents are taught specific skills. These skills are then practiced in the following six Coach sessions. The current protocol utilises a fixed approach to dosage, with all families receiving seven weekly, 60-minute intervention sessions. Prior research indicates improved outcomes and lower attrition rates using a fixed approach to dosage.

The therapy will be delivered by a provisional, general or clinically registered psychologist trained in the protocol, one-on-one in a research setting.

Parents will be provided handouts designed specifically for this study. These handouts will include the skills taught and age-appropriate toys recommended for 5 minutes of daily practice. Each week, parents will be given homework sheets to complete detailing whether they completed their daily practice, what toys they used, and problems or questions that arose during daily practice.

Adherence to the protocol will be monitored via the number of sessions that participating families attend and adherence to session and homework demands/requirements (i.e., five minutes of daily skill practice).

Number of Participants:
This open trial research will involve N=10 families with children aged 12-24 months with emerging disruptive behaviours. PCIT attrition rates for children with clinically significant conduct problems have ranged from 33% to 36%, thus we expect an attrition rate of approximately 35%. Accounting for attrition, a total of 13 families (children and parent/caregiver dyads) will be recruited for the open trial.

Statistical Analyses:
Acceptability of the intervention will be tested using descriptive analyses to examine mean scores on the resolved treatment satisfaction measure at follow-up assessments, average rates of session attendance and homework completion across treatment, and the participant dropout rate.
The preliminary efficacy of the intervention will be tested by examining change in primary outcomes during and post-intervention using linear mixed models.
To test for clinically significant differences, Cohen's d effect size differences between pre- and post-scores for primary outcomes will be examined.
