Abstract

BACKGROUND:

Parental language is associated with children's later language development. Parenting programmes, based on social learning theory, enhance a range of parenting behaviours, yet there is limited evidence for their effect on parental language.

AIM:

To assess the benefits of a behavioural-based parenting programme, which features components of language and communication, to enhance parental language.

METHOD:

Parents of toddlers, aged 12 to 36 months, were recruited from eight Flying Start early intervention centres across Wales. Participants were randomised 2:1 either to a parenting programme (n = 60) or to a wait-list control group (n = 29). Researchers were blind to participant allocation throughout the trial. Fifteen-minute video-recorded observations of parents and children interacting during free-play, both at a pre-intervention and at 6-month follow-up, provided the data for the study. Five observed measures of parental language were assessed; quantity and variety, encouraging, critical, child-led and parent led interactions.

INTERVENTION:

The Incredible Years Parent-Toddler Programme (IYPTP) is a 12-week group-based behavioural intervention that teaches effective relationship and behavioural management skills including social, emotional and persistence coaching to enable parents to better support their children's development.

RESULTS:

Of 89 dyads that completed pre-intervention assessments 81 (54 intervention and 27 control) met the criteria for the current study. Intention to treat analysis indicated that child-led language interactions significantly benefited from the intervention [regression coefficient (B) = -1.44, 95% confidence intervals (CI) = -2.59 to -0.29, P = 0.015, effect size (ES) = 0.47] and a positive trend for encouraging language in favour of the intervention sample was evident. Per-protocol sample analysis replicated these findings with encouraging language reaching statistical significance (B = 1.07, 95% CI = 0.11 to 2.03, P = 0.03, ES = 0.52). No further benefits were evident.

CONCLUSIONS:

The IYPTP has limited evidence as an effective programme for enhancing some aspects of parental language.
