Study Participants

Parents eligible to participate in the study (1) were the primary caretakers of children younger than 5 years of age, (2) spoke English as their first language, and (3) had an intellectual disability. A total of 63 parents from 57 families were recruited; of these, 45 parents from 40 families completed the project. The authors categorized the sample as follows: 82 percent of the parents were from an English-speaking background, 13 percent were from a culturally and linguistically diverse background, and 5 percent were Aboriginal or Torres Strait Islanders.

Comparison Conditions

The research design permitted all parents to receive the HLP in a staggered sequence. Initially, each parent was randomly allocated to one of three groups. However, a fourth group was created of parents who were referred late and would not have been able to complete the staggered sequence. During the first intervention phase, Group 1 (n = 20) received the full HLP intervention. Group 2 (n = 11) received home visits but no parent education. Groups 3 and 4 (n = 10 and n = 4, respectively) received business-as-usual services in this phase. Assessment 2 occurred after the first intervention phase. During the second intervention phase, Group 2 received HLP, Group 3 received lesson booklets only, and Group 4 received HLP. Assessment 3 occurs after this phase. At this point, all groups had received some portion of the intervention.
