This study longitudinally compared the costs and effects of 2 alternative forms of early intervention that differed with respect to the roles assumed by parents and professionals: a home parent training intervention and a clinic-based, low-parent-involvement intervention. Ss were 40 3-4 yr olds with moderate speech and language disorders, half of whom were assigned to each intervention. Results of follow-up testing at 42 mo indicate that the home parent training group performed as well as the clinic-based group on measures of speech and language functioning, as well as on measures of general development and family functioning. The comparable longitudinal effects of the 2 interventions suggest the viability of programs that offer options to parents and the need for interventionists to be trained broadly enough to be able to assume a variety of roles and to provide a range of services.
