Brief Summary
The purpose of this study is to analyze the effect of an interactive parent-child book reading intervention. The intervention includes two components: the provision of five children's books to parent-child dyads and information about how to practice interactive book reading. The investigators expect to find an effect of this intervention on a) infants' expressive vocabulary, b) reading activity, c) parental expectations and knowledge about language development and d) parental use of interactive book reading strategies.

Outcome Measures
Primary Outcomes (1)
Change in infant expressive vocabulary
Infant expressive vocabulary will be measured with the short form (SF) Spanish versions of the MacArthur-Bates Communicative Development Inventories (CDI). Parents will complete version I (CDI-SFI) of the inventory at baseline and version II (CDI-SFII) of the inventory at posttest. Scores on the CDI-SFI inventory range from 0 to 104. Scores on the CDI-SFII inventory range from 0 to approximately 100-135, depending on the complexity of the participant's linguistic production. For both inventories, higher scores indicate a better outcome.
Baseline [15 to 17-months] and Posttest [18 to 20-months].
Secondary Outcomes (3)
Change in parental report of reading activities
Baseline [15 to 17-months] and Posttest [18 to 20-months].
Change in parental expectations and knowledge about language development
Baseline [15 to 17-months] and Posttest [18 to 20-months].
Change in parental use of interactive book reading strategies
Baseline [15 to 17-months] and Posttest [18 to 20-months].
Study Arms (2)
Interactive Book Reading Group
EXPERIMENTALParticipants in this arm will take baseline measures, will receive the intervention and will take posttest measures.
Control Group
NO INTERVENTIONParticipants in this arm will take baseline and posttest measures. For ethical purposes, they will receive the intervention after posttest measures are taken.
Interventions
The intervention is a package including five children's books and information on how to practice interactive book reading. Information includes 36 audiovisual products delivered via text messaging over a 12-week period. Products include: 1. An introductory video about interactive book reading, along with a written list of recommendations on how to practice interactive book reading. 2. Two videos of child development experts explaining the benefits of interactive reading. 3. Thirty written text messages strengthening content provided in the videos. 4. Three audio messages guiding the progress of the intervention. Based on Abraham and Michie's (2008) taxonomy of behavior change techniques, one audiovisual product prompts specific goal settings, 13 provide instruction, one provides information on consequences, 10 prompt practice, three use follow-up prompts, one prompts self-monitoring of behavior, one models or demonstrates the behavior and six prompt barrier identification.

- Masking Details
- An external collaborator will create the allocation sequence for each of the two participating health centers (stratified randomization). Two independent research assistants will prepare the allocation in sequentially numbered, opaque, sealed and stapled envelopes. Aluminium foil inside each envelope will be used to render the envelope impermeable to intense light. This will allow the allocation sequence to be concealed from the researcher assessing participants at baseline. Once baseline assessment is completed, the next consecutively numbered envelope will be opened to reveal the participant's allocation. Treatment for the experimental group will be provided by two different researchers who will not participate in outcome assessment. A different researcher (outcome assessor), blind to the allocation sequence, to the participant's allocation and to the participant's baseline scores, will complete the participants' assessments during posttest.
