The ESDM is a manualized comprehensive treatment model for young children (12-48 months). In the preschool based ESDM, learning objectives are guided by the ESDM curriculum checklist, which includes developmental skills in language, play, motor skills, personal independence, imitation and cognition.

The eclectic approach consists of a combination of methods from several treatment-models. Individualized educational plans are based on multi-disciplinary assessment, and include objectives in several domains - communication, social-skills, play, emotional adjustment, adaptive daily skills, motor skills and cognition. They are presented to parents at the beginning of the year and are reviewed by the staff three times a year.

The ESDM is a manualized comprehensive treatment model for young children (12-48 months). In the preschool based ESDM, learning objectives are guided by the ESDM curriculum checklist, which includes developmental skills in language, play, motor skills, personal independence, imitation and cognition. The objectives are monitored for progress during each session The sessions are conducted according to ESDM principles, and include weekly parent-coaching session, in which parents observe the therapist interact with the child while applying various teaching techniques, and then implement these techniques during the interaction with their child. Additionally, parents get acquainted with the daily objective sheet and are encouraged to work on these objectives at home as well. Finally, in this model, therapist adherence to the ESDM practices are monitored according to the ESDM fidelity rating system

A standardized measure of early development which is administered to children from birth to 68 months of age. The MSEL includes five subscales: receptive language, expressive language, visual reception, fine motor, and gross motor skills, for which a standard T score and age equivalents (AE) are computed, together with a total composite of intellectual ability. Administration time - 30-60 minutes (Mullen, 1995).

A structured interview measuring adaptive behavior from birth to adulthood. This measure is divided into 11 sub-scales, clustered into four domains: communication, daily living skills, socialization and motors skills. Standard scores and age equivalents can be obtained from this measure, together with an adaptive behavior composite (ABC). The VABS-II may be administered via a structured interview with the caregiver or teacher, or using a self-report questionnaire filled out by the responder. In the current study, both forms of administration will be used, so that parents will be interviewed by a trained practitioner, and teachers will be given the self-report version of the test. Administration time - 45-60 minutes (Sparrow, Cicchetti & Balla, 2005).

A 16 item self- report questionnaire designed to measure parental sense of efficacy and satisfaction in parenting. The 16 items of the inventory are rated on a 6 point Likert scale, with higher scores indicating to higher sense of efficacy and satisfaction. The PSOC was reported by the authors to have adequate internal reliability for both subscales. Additionally, the PSOC was found to be negatively correlated with measures of child behavior problems (Johnston & Mash, 1989).
