The intervention is a short term parent training program based on behavioral principles, which can be delivered by trained therapist. The manual includes eleven core sessions, home visit session, follow-up telephone booster sessions and seven supplemental sessions, designed to be delivered individually to parents in an outpatient setting.

The protocol will be administered to groups of 3-4 parents, with a quantitative pretest-post test design evaluated at five time points, including a follow up at one month post intervention. The protocol will be administered in various community and educational locations, such as schools and community centers

A caregiver and teacher report measure of disruptive behaviors including 58 items, each rated on a four-point Likert scale (0-3), with higher scores indicative of more severe problem behavior. Includes five subscales: Irritability (tantrums, aggression and self-injury, 15 items); Social Withdrawal (16 items); Stereotypic Behavior (7 items); Hyperactivity (16 items); and Inappropriate Speech (4 items). In children with ASD, the ABC subscales demonstrate adequate internal consistencies (α=.77-.94) and convergent validity (Kaat, Lecavalier, & Aman, 2014).

The measure will be administered at different time points on order to follow changes in the disruptive behaviors of the participants.

A caregiver-rated scale for child noncompliance across 24 everyday situations. Each item is rated as a problem: ''yes'' or ''no''; ''yes'' items are then scored from 1 (mild) to 9 (severe), on two subscales: 'Demand-Specific' and 'Socially Inflexible' (Chowdhury et al. 2010). The total severity score is divided by 24 to obtain a per item mean.

A caregiver - and teacher-report measure of child social competence with 65 items, each rated on a four-point Likert scale (1-4), with higher scores indicative of more problematic social-related behaviors, in the domains of social awareness, social cognition, social communication, social motivation, and autistic mannerisms (e.g., restricted or repetitive behaviors). All subscales have acceptable internal consistency (α = .77-.92) and test-retest reliability (Constantino et al., 2003)

A self-report inventory designed to measure the overall level of parenting stress an individual is experiencing and it examine stressors associated specifically with the parental role and do not include stresses associated with other life roles and events. The PSI-SR has strong psychometric properties and has been used in a number of studies of autism and parent training, and was also found valid and reliable when tested on Israeli parents (sharf 1989; Turkel 2002). It contains 36 items, each rated on a five-point Likert scale (1-5), with higher scores indicative of more parenting stress and includes Parental Distress (PD), Parent-Child Dysfunctional Interaction (P-CDI) and Difficult Child (DC) sub-scales.
