Extended Abstract



Background: The first thousand days of life—from pregnancy to the early years of childhood—represent a sensitive developmental period during which neurobiological maturation, socio-emotional regulation, and early relational patterns are rapidly shaped. Research across developmental psychology, psychiatry, and public health indicates that parental mental health and the quality of early caregiving interactions are among the strongest predictors of later child wellbeing. Perinatal depression and anxiety, heightened parenting stress, and reduced caregiver emotional availability can weaken sensitive responsiveness and early bonding, increasing risk for suboptimal developmental trajectories. Importantly, parenting is not an isolated individual practice but a family-embedded process. In Iran, parenting is often situated within multigenerational family systems and dense informal support networks. At the same time, parents—especially mothers—face strong cultural norms about “good parenting” and growing exposure to contradictory advice in digital environments. These pressures can contribute to uncertainty, decision fatigue, and distress, with spillover effects on coparenting and overall family functioning. Despite evidence supporting parenting and perinatal mental health interventions, implementation at scale remains limited due to inequities in access, shortages of specialized providers, and barriers to in-person services. Many programs also focus on a single time period, address a narrow set of outcomes, or lack structured screening and referral pathways required for safe delivery in real-world settings. Blended approaches that integrate digital education with structured screening and targeted human support offer a promising pathway toward scalable prevention, but they must be culturally responsive and developmentally staged for Iranian contexts.



Aim: This paper introduces the design and evaluation protocol for “Little Traveler”, a preventive, empowerment-oriented, stage-based parenting program designed to accompany Iranian parents from pregnancy to 36 months postpartum. The program was developed as an independent intervention-development initiative based on a review of evidence on parental mental health, early child development, and parenting interventions. It has not previously been used in a thesis, published study, or prior internal document, and the present article constitutes its first formal protocol report. The protocol specifies the program’s intervention architecture, outcome framework, SPIRIT-aligned assessment schedule, and statistical analysis plan, providing a rigorous foundation for subsequent effectiveness and implementation evaluations.



Intervention Overview: “Little Traveler” is organized into five sequential developmental pathways: pregnancy (weeks 12–38), 0–6 months, 6–12 months, 12–24 months, and 24–36 months. Each pathway addresses age-specific developmental tasks and family challenges while maintaining a stable three-component structure:

1. Stage-based psychoeducation with a coaching logic: brief, evidence-informed modules tailored to developmental needs. Units are paired with feasible daily micro-practices, goal setting, and feedback loops to support behavior change. The program is explicitly positioned as non-therapeutic and empowerment-focused, consistent with parenting coaching principles rather than clinical treatment.

2. Structured screening and monitoring: periodic low-burden assessments of parental mental health, parenting stress, parenting self-efficacy, and parent–child bonding indicators. Child development is monitored through age-appropriate milestone checklists to support early identification of potential concerns.

3. Stepped support and referral pathways: families are assigned to standard education, enhanced supportive follow-up, or specialized referral pathways based on screening results and risk indicators. A safety escalation procedure is embedded for urgent risk situations.

While mothers are the primary participants, father involvement is encouraged through dedicated content related to coparenting and supportive fathering. The program also acknowledges the role of extended family members—particularly grandmothers—in Iranian caregiving contexts and anticipates indirect engagement through educational alignment and conflict-reduction strategies.



Participants: Eligible participants include Iranian mothers aged 15 years or older who are pregnant or have a child aged 0–36 months, have basic access to mobile/internet, and can read Persian. Participation is voluntary and preventive. Exiting the standard educational pathway is treated as pathway adaptation: families with high-risk indicators are redirected to supportive monitoring or specialized referral as appropriate.



Outcomes and Measurement Framework: Primary outcomes reflect preventive targets at individual and relational levels: postpartum depression symptoms, general psychological distress (depression–anxiety–stress), parenting stress, parenting self-efficacy, parent–child bonding indicators, and child milestone monitoring. Secondary outcomes include family-relevant constructs aligned with interdisciplinary family research: parenting literacy, reflective functioning, marital satisfaction, coparenting quality, intergenerational family dynamics, and digital information-related anxiety/decision fatigue. Exploratory outcomes examine engagement–outcome associations and potential moderators (e.g., household structure, employment, education). Assessments occur at entry (baseline), at the end of each developmental pathway, and at key checkpoints (6, 12, 18, 24, and 36 months), and will be reported using SPIRIT-consistent timelines and tables.



Methodology: Analyses will follow an intention-to-treat principle, reflecting engagement variability typical of digital and blended interventions. Longitudinal change will be modeled using mixed-effects approaches (linear mixed models for continuous outcomes; generalized mixed models for ordinal/categorical outcomes), enabling estimation under incomplete data patterns. Time and developmental pathway will be included as fixed effects with participant-level random effects. Exploratory models will examine dose–response relationships between engagement indicators (e.g., content exposure, session participation, screening completion, father involvement) and outcomes. Where feasible, latent growth or structural equation modeling will be used to examine developmental and family-process pathways. The protocol prioritizes confidentiality, data security, and minimal emotional burden. Data are stored in coded form without personal identifiers and access is restricted to authorized personnel. The program is explicitly framed as non-clinical and not a substitute for professional mental health care. A multi-tier safety protocol supports early detection and referral for high-risk cases.



Conclusion: “Little Traveler” presents a culturally responsive, stage-based, blended protocol for preventive parenting support, spanning from pregnancy through early childhood. By integrating education, structured screening, and stepped support within a family systems and interdisciplinary lens, the protocol addresses the psychological, relational, and sociocultural dimensions of parenting in Iran. This work provides a transparent foundation for subsequent effectiveness trials and implementation research, contributing to family research agendas focused on parenting, family wellbeing, and early developmental equity.
