Description of intervention(s) / exposure
The intervention (called `Hitkashrut`):
In October 2006 a research pilot was initiated with kindergarten teachers in order to create Israeli norms for a screening instrument and to test screening and referral procedures in collaboration with national supervisors of Ministry of Education`s Preschool education division. Master-level educational psychologists working at three local services in the Jerusalem region co-facilitated a manual-based sequence of semi-structured two-hour meetings with groups of 5-7 couples. Sessions were conducted once weekly over a period of 14 weeks and were organized according to a 4-part structure: joining and following-up on last session’s homework; psycho-educational instruction with facilitators’ modeling problematic and optimal behaviors using prepared role plays; group discussion including spontaneous parental role plays; summary of take-home points and home-work assignments. Handouts summarized each session and highlighted the take-home points. Behavior management skills were learned and practiced by establishing differential reinforcement programs with each parental dyad during a half-hour couple meeting with one facilitator (after session 5 only), followed by one phone call and in-session checkups.

Behaviour
Comparator / control treatment
Minimal Support Control Group. The parents were referred for two consultation sessions (2 hours). Sessions occurred at baseline and 3 months later, and were administered by Master-level educational psychologists to each couple. The facilitators made use of Hitkashrut’s key components and handouts, and where necessary referred parents to regular community care.
