Brief Summary
The goal of this study is to determine whether an intervention to support caregivers in engaging with their children while using educational media together can improve children's early literacy skills, compared to an aligned shared book reading intervention and to no intervention. Given that early literacy skills predict children's later academic learning, this home intervention, which aims to shape the communication patterns surrounding a common, family-friendly activity, has the potential to positively influence the trajectory of low income children's academic success. The investigators propose that amedia based activity will reduce barriers and increase adherence therefore increasing literacy skills over time.

Outcome Measures
Primary Outcomes (6)
Print concept knowledge
Children are administered the Preschool Word and Print Awareness (PWPA) measure (Justice et al., 2006), which examines children's knowledge of 16 basic print concepts. The PWPA has high inter-rater reliability (96% to 100%, Justice \& Ezell, 200), acceptable internal consistency (#= .7; Dobbs- Oates et al., 2015) and can reliably estimate preschoolers' print-concept knowledge (Justice et al., 2006).
At pretest after enrollment and at posttest after the 12 week intervention period
Alphabet knowledge
Children are administered the Alphabet Knowledge subtest of the Phonological Awareness Literacy Screening - Preschool (PALS-PreK; Invernizzi et al., 2001). Children are presented with uppercase and lowercase letters printed in random order and receive a point for each letter named correctly. Cronbach's alphas average average .86. Inter-rater reliability is \>.96 (Invernizzi et al., 2004). The full PALS-PreK test is highly correlated with measures of reading ability (e.g., Test of Early Reading Ability, r= .67) and predicts later performance on a similar literacy measure (rs \> .53). Further, this subtest has high predictive validity in discriminating children who will later be identified as needing additional instruction (Invernizzi et al., 2001).
At pretest after enrollment and at posttest after the 12 week intervention period
Name Writing
Children are administered the Name Writing subtest from the PALS-PreK. In the Name Writing subtest, the child is asked to draw a picture of themselves and then write their name. They are then asked to show the assessor their name. Only the written name is scored. This subtests has high inter-rater reliability (.99). As noted above, the full test has good convergent and predictive validity (Invernizzi et al., 2001).
At pretest after enrollment and at posttest after the 12 week intervention period
Phonological Awareness
Children are administered two subtests from the PALS-PreK. In the Beginning Sound Awareness subtest, the child is asked to produce the beginning sound of a word. This subtests has acceptable reliability (# = .93) and inter-rater reliability is high (.99). As noted above, the full test has good convergent and predictive validity (Invernizzi et al., 2001). The Rhyme Awareness subtest was removed in February 2026 due to feasibility concerns identified in early study data.
At pretest after enrollment and at posttest after the 12 week intervention period
Word reading
At all timepoints, children are administered the Letter-Word Identification subtest of the Woodcock Johnson IV Test of Achievement (WJ IV; Schrank, McGrew \& Mather, 2014). This subtest requires children to identify or read isolated letters and words orally. This subtest has adequate internal-consistency (.94; Schrank \& Wendling, 2018). It has a high factor loading onto the Broad Reading cluster (.92; McGrew et al., 2014) which is highly correlated with other measures of reading like the Wechsler Individual Achievement Test (WIAT) Total Reading (.89; Schrank \& Wendling, 2018). It is strongly correlated with general school readiness (r = .84) as measured by the Differential Ability Scales (McGrew et al., 2014).
At pretest after enrollment, at posttest after the 12 week intervention period, at 3-month follow up, at 6-month follow-up, and at 12- month follow up
Spelling
At all timepoints, children are administered the Spelling subtest from the WJ IV, requiring children to draw lines, trace and write letters, and spell orally presented words. This subtest has adequate internal-consistency reliability (.92; Schrank \& Wendling, 2018) and a high factor loading onto the Broad Written Language Cluster (.87), which is highly correlated with other measures of writing like WIAT Written Expression (.77; McGrew et al., 2014). This subtest is moderately correlated (r = .69) with general school readiness as measured by the Differential Ability Scales (McGrew et al., 2014).
At pretest after enrollment, at posttest after the 12 week intervention period, at 3-month follow up, at 6-month follow-up, and at 12- month follow up

Study Arms (3)
Media instruction
EXPERIMENTALCaregivers will be asked to implement joint media sessions with their child four times per week for 12 weeks using lightly adapted versions of the commercially-available Super Why! program, which focuses on early literacy skills, including alphabet knowledge, rhyming, spelling, and print concepts. Sessions are anticipated to last 20 minutes. Caregivers will be trained by researchers on explicit strategies to use to promote children's learning. Caregivers will digitally log every session and audio record 1 session each week.
Storybook instruction
ACTIVE COMPARATORCaregivers will be asked to implement joint storybook reading sessions with their child four times per week for 12 weeks using adapted versions of the commercially -available Super-Why! storybooks, which focus on early literacy skills including alphabet knowledge, rhyming, spelling, and print concepts. Sessions are anticipated to last 20 minutes. Caregivers will be trained by researchers on explicit strategies to use to promote children's learning. Caregivers will digitally log every session and audio record 1 session each week.
Business-as-usual control
NO INTERVENTIONCaregivers will be asked to log any joint learning activities they engage in with their child but will not be provided with any specific materials or instructions.

Data Sharing
- IPD Sharing
- Will share
- Time Frame
- Data will be made available upon publication of major findings from the proposed study. Study data deposited in the OSF, Databrary, and CHILDES/TalkBank will be available to the research community in perpetuity.
- Access Criteria
- Deidentified datasets will be made available as public use data on the OSF. Data with potentially personally identifiable information, such as audio or video, will be shared in more restricted manner via Databrary. Databrary provides data access to authorized users who have been granted secure access by Databrary's administrators. Only researchers with Principal Investigator status from institutions with Institutional Review Boards or similar review entities, or researchers affiliated with Principal Investigators, will be authorized for access. Transcripts will be shared via CHILDES/TalkBank and will be redacted as needed to remove potentially personally identifiable information.
This project will generate quantitative data from 450 families and children, which will be used to assess the efficacy of a media-based early literacy intervention. The data will be collected via direct assessments, questionnaires, applications loaded onto provided tablets, and audio and video observations. The primary final, cleaned data will consist of a single comma-delimited file for all valid responses. Transcription records will be stored as text files and audio/video files will be stored as MP3/4 files. Upon publication of major findings from the proposed study, the primary data file, transcripts, and audio and video files will be shared with other researchers through the Open Science Framework (primary comma-delimited data file), Databrary (audio and video files), and CHILDES/TalkBank (transcripts).
