The purpose of this randomized controlled trial is to explore the efficacy of amplifying dialogic reading training provided to families of infants and toddlers in the ROR program using a novel, smartphone-based application (Rx for Success; RS). The RS app includes videos modeling dialogic reading for a variety of child ages, interactive games, and text messaging reminders to empower parents and other caregivers to increase constructive cognitive and social-emotional stimulation in the home through book sharing. This study addresses an evidence gap regarding the efficacy of dialogic reading training to improve cognitive and social-emotional health using a mobile, technology-based approach. It leverages existing ROR infrastructure and will provide valuable pilot data to improve and scale this inexpensive clinical resource and guide future longitudinal studies, to better serve low-SES, at-risk families.
Aims and hypotheses are as follows:
Specific Aim 1 (Rx for Success; RS): To explore the efficacy of incorporating dialogic reading training via the RS application into ROR during well-child visits for infants (6-12 months old) and toddlers (18-24 months old), compared to standard ROR practice.
Hypothesis 1a (language): Language scores (LENA Snapshot) will be higher in children whose caregivers are provided with the RS app.
Hypothesis 1b (social-emotional): Social-emotional development scores (DECA-I/T items) will be higher in children whose caregivers are provided with the RS app.
Hypothesis 1c (dialogic quality): Dialogic reading quality scores (DialogPR) will be higher in caregivers presented with the RS app.
Hypothesis 1d (attitudes): Attitudes towards shared reading at home (StimQ-I/T items) will be higher in families provided with the RS app.
Specific Aim 2 (exploratory): To explore the effect of providing a smartphone-based app versus a specially designed children's book on screen-based media use.
Hypothesis 2a: Reported screen-based media use (ScreenQ) will be lower in families provided with the RS app, reflecting greater emphasis on interactive shared reading.
Hypothesis 2b: Language (LENA Snapshot) and social-emotional (DECA-I/T items) scores will be higher for children with less reported screen-based media use (ScreenQ).

|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||252 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||
This is a prospective, randomized controlled trial involving 2 age categories of low-SES caregiver-child dyads served by the ROR program, each followed for 6 months. For each category, a baseline assessment (pre-) and an outcomes assessment (post-) will be conducted. Category 1 will involve 6 month-old infants, followed until they are 12 months old. Category 2 will involve 18 month-old toddlers, followed until they are 24 months old.
Families assigned to the control arm in each age category will receive customary ROR, and reading-related developmental surveillance and anticipatory guidance. Control families will also receive a new children's book reinforcing AAP screen-based media recommendations. Families in the intervention arm will receive "enhanced" ROR involving the provision of the Rx for Success (RS) application at the baseline visit (6 months old and 18 months old, respectively).
|Masking Description:||Families enrolled in the study will be blinded to its specific aims, other than "We are looking at ways to make reading with children at home more fun and interactive."|
|Official Title:||Rx for Success: A Randomized Controlled Trial of Technology-Based Dialogic Reading Training|

Active Comparator: Control - screen time reduction
Families assigned to the control arm in each age category will receive customary ROR, including the provision of an age-appropriate children's book, and reading-related developmental surveillance and anticipatory guidance. In addition, control families will receive a new children's book reinforcing AAP screen-based media recommendations.
Other: Control - screen time reduction
Control families will receive a new, specially designed children's book regarding limiting screen-based media use and encouraging healthy/active alternatives (Baby Unplugged: Play, Hutton/Jones, blue manatee press), which lists American Academy of Pediatrics screen time recommendations on the back cover.
Experimental: Rx for Success Smartphone Application
Families in the intervention arm in both age categories will receive "enhanced" ROR involving the provision of the Rx for Success (RS) application at the baseline visit (6 months old and 18 months old, respectively). No additional intervention will take place, other than "push" notifications and other content such as demonstration videos built into the RS application.
Other: Rx for Success Smartphone Application
The Rx for Success (RS) mobile application (app) was developed by the non-profit, Children, Inc. The app is designed to be informational and motivational with both video and cueing content. The app uses a "View It, Cue It, Do It" model that allows parents to quickly download the smartphone app, view brief videos of age-indexed, research-based language enrichment practices; and regulate a push notification cueing program. Videos embedded in the RS app provide a summary of dialogic reading tailored for the child's age, and suggestions for encouraging verbal interactivity and social-emotional engagement through dialogic reading. Key behaviors reinforced by the app include discussing the story before reading to build interest and enthusiasm, followed by interactive reading modeled by specific types of verbal/behavioral prompts for the parent to make and responses to what the child says or does.
- Language [ Time Frame: 6 months ]Comparison of scores on the LENA Snapshot parent report measure before and after DR intervention between intervention and control groups.
- Social-emotional [ Time Frame: 6 months ]Comparison of scores on items exerpted from the DECA-I/T Measure, attachment sub scale between intervention and control groups.
- Home reading behaviors [ Time Frame: 6 months ]Comparison of scores on items exerpted from the StimQ-I/T and DialogPR-IT measures between intervention and control groups.
- Screen-based media use [ Time Frame: 6 months ]Comparison of ScreenQ scores (screen-based media use at home) between intervention and control groups.
