Model description

The Lidcombe Programme is a speech and language intervention targeting children aged between 3 and 6 years with a diagnosed stuttering problem.

The intervention is delivered by qualified speech and language therapists who are trained to use the manualised Lidcombe protocol. It is delivered in two stages that are determined by the child’s progress with a typical period of treatment lasting between 6 and 12 months.

During stage one, parents attend weekly visits where they are coached in strategies in responding appropriately to periods of stutter-free speech and unambiguous stuttering. Parents are expected to set aside time to work with their child on a daily basis, as well as to develop strategies for everyday interactions. Stage two begins once the child’s stuttering has disappeared or dropped to a very low level. At this point, clinic visits are reduced but not stopped so that parents can learn maintenance strategies should the stuttering reappear.

Age of child

Target population

Young children aged 3 to 6 years with a diagnosed stuttering problem

Why?

Science-based assumption

Stuttering in children typically occurs between the ages of 2 and 5.

Science-based assumption

Parents can reduce the incidence of stuttering in their children through verbal and non-verbal behaviour, designed to encourage fluent speech.

Who?

Science-based assumption

Children aged 3 to 6 years old with an identified stuttering problem.

How?

Intervention

Parents learn how to praise and acknowledge stutter-free speech, acknowledge unambiguous stuttering, and encourage their children to correct themselves when they stutter.

What?

Short-term

Parents are better able to encourage fluent speech without causing their child distress.

Medium-term

Children’s verbal ability improves.

Long-term

Stuttering is reduced.

Who is eligible?

Young children aged 3 to 6 with a diagnosed stuttering problem.

How is it delivered?

The Lidcombe Programme is delivered in 16 sessions of 45 to 60 minutes’ duration each by one speech language therapist, speech pathologist or speech-language pathologist, to individual families.

What happens during the intervention?

The intervention starts with a structured conversation that is designed to facilitate stutter-free speech. This allows the parent the opportunity to present plenty of positive verbal reinforcement to encourage fluent speech.

The first stage of the intervention consists of training sessions at home where they are taught how to respond appropriately to encourage fluent speech.

When parents have been observed practising the various behaviours designed to encourage stutter-free speech, the conversations progress to less structured conversations outside the training sessions and outside the home.

Who can deliver it?

The practitioner who delivers this intervention is a speech and language therapist, speech pathologist, or speech-language pathologist.

What are the training requirements?

The practitioners have 14 hours of intervention training. Booster training of practitioners is recommended.

How are the practitioners supervised?

It is recommended that practitioners are supervised by one host agency supervisor.

What are the systems for maintaining fidelity?

Is there a licensing requirement?

The Lidcombe Programme’s most rigorous evidence comes from two RCTs conducted in New Zealand and Germany consistent with Foundations’ Level 2 evidence strength threshold.

Children in the intervention group showed statistically significant reductions in stuttering at post-intervention.

The Lidcombe Programme has preliminary evidence of improving a child outcome, but we cannot be confident that the intervention caused the improvement.

Evidence ratings:

Rated 2: Has preliminary evidence of improving a child outcome from a quantitative impact study, but there is not yet evidence of causal impact.

Rated 2+: Meets the level 2 rating and the best available evidence is based on a study which is more rigorous than a level 2 standard but does not meet the level 3 standard.

Rated 3: Has evidence of a short-term positive impact from at least one rigorous study.

Rated 3+: Meets the level 3 rating and has evidence from other studies with a comparison group at level 2 or higher.

Rated 4: Has evidence of a long-term positive impact through at least two rigorous studies.

Rated 4+: Meets the level 4 rating and has at least a third study contributing to the Level 4 rating, with at least one of the studies conducted independently of the intervention provider.

Rating has a *: The evidence base includes mixed findings i.e., studies suggesting positive impact alongside studies, which on balance, indicate no effect or negative impact.
