Family child care providers and their assistants.

PlayReadVIP (formerly the Video Interaction Project) is an intervention that uses a strengths-based reflective-practice model to coach parents on positive parenting interactions with their children during book reading and play.

Provider self-efficacy is measured using the Beliefs About Parent Support for Early Literacy Scale (BPSES). The BPSES consists of items assessing providers' confidence in managing children's behavior and supporting children's development. Items are rated on a 5-point Likert scale ranging from Strongly disagree to Strongly agree. The total score is calculated by summing all five items, and ranges from 5 to 25, with higher scores indicating greater provider self-efficacy.

The Provider Perception survey was developed by the NYULH PlayReadVIP research team and includes frequency-based items assessing how often children in the provider's care engage in literacy-related behaviors, social interaction, communication, sustained attention during reading, and challenging behaviors. Each item is rated on a 10-point Likert scale from 0-9. The total score is the sum of responses and ranges from 0-72, with higher scores indicating greater frequency of the specified behaviors.

The StimQ-2 is a standardized, validated caregiver-report measure designed to assess the quality and frequency of cognitive stimulation activities provided to children in early childcare settings. The instrument includes 5-point Likert scale from 0-5 across multiple domains, including shared reading practices, caregiver teaching activities, verbal responsiveness, and availability of developmentally appropriate learning materials. The highest total StimQ Score is 39 and the lowest is 0. Higher scores indicate greater provision of cognitive stimulation within the caregiving environment.

The Child Care Worker Job Stress Inventory (CCW-JSI) is a survey that includes items drawn from three domains: job demands, job resources, and job control. Items are rated on a 5-point frequency scale ranging from 1-5; the total score is calculated as the sum of item responses and ranges from 51 to 255; higher scores indicate greater provider-reported job stress.
