Dialogic Book-Sharing intervention in an Italian multicentre randomized controlled trial: effects on parental mood.
Abstract
This randomized controlled trial (RCT) was conducted in 10 Italian health and maternal-child Centres to evaluate the effects of a Dialogic Book-Sharing (DBS) intervention on parental symptoms of anxiety and depression. Sixty-eight parents of 14-20-month-old infants were recruited. ANOVA analysis revealed a greater reduction in anxiety and depression symptoms in the intervention group (N = 36) compared to controls (N = 32). DBS is a simple, cost-effective programme that benefits parental mood, making it a valuable intervention for perinatal populations.
Clinical relevance
Perinatal parental anxiety and depression are highly prevalent and carry well-established risks for adverse infant neurodevelopmental and attachment outcomes, yet scalable, low-resource interventions targeting parental mood within primary care settings remain limited. This multicentre Italian RCT addresses that gap by evaluating Dialogic Book-Sharing (DBS)—a structured, wordless picture-book interaction programme—as a psycho-educational tool with dual benefit: supporting early parent–child communication while simultaneously ameliorating parental affective symptoms. Given the post-pandemic surge in perinatal mental health burden and the limited reach of specialist psychiatric services, a community-deliverable intervention of this kind has immediate relevance for primary care and maternal–child health clinicians.
Key findings
1. Study design: Multicentre RCT conducted across 10 Italian health and maternal-child centres, with 68 parents of 14–20-month-old infants randomised to DBS intervention (N = 36) or control (N = 32). 2. Primary outcome – anxiety: ANOVA analysis demonstrated a statistically greater reduction in parental anxiety symptoms in the DBS intervention group compared to controls (specific effect sizes, F-statistics, and p-values not reported in the available abstract). 3. Primary outcome – depression: ANOVA similarly revealed a significantly greater reduction in parental depressive symptoms in the intervention group versus controls (quantitative parameters including confidence intervals and p-values not reported in the available abstract). 4. Population specificity: The target cohort of parents with infants aged 14–20 months situates DBS within the critical 'first thousand days' developmental window, a period of heightened parental psychological vulnerability. 5. Intervention profile: DBS is described as a simple and cost-effective programme, suggesting favourable feasibility and scalability for perinatal primary care settings without requiring specialist mental health infrastructure. 6. Limitation noted: The abstract does not report effect sizes, confidence intervals, p-values, NNT/NNH, or details on outcome measurement instruments; clinicians should review the full publication for these data before implementing practice change.
Practice implications
Primary care clinicians, paediatricians, and perinatal mental health teams working with parents of infants aged 14–20 months should consider DBS as an adjunctive, low-intensity psycho-educational intervention that may reduce subclinical anxiety and depressive symptoms without requiring specialist referral. Given its community-based, group-deliverable format within maternal–child health centres, DBS could be integrated into routine well-baby visit infrastructure as a tiered-care component for parents who screen positive on validated tools (e.g., EPDS, GAD-7) but do not meet thresholds for pharmacotherapy or formal psychotherapy. Pending full publication of effect sizes and confidence intervals, adoption should be framed as supplementary to—rather than a replacement for—evidence-based perinatal mental health treatments, with clinicians monitoring parental mood longitudinally to identify those requiring escalation of care.
