Validation of a Parent Report Tool for Monitoring Early Vocal Stages in Infants.
Article in Journal of speech, language, and hearing research : JSLHR, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose Tracking of infants' progression through early vocal stages supports the identification of children at risk for language delays and guides early intervention for children with disabilities. However, few clinical tools are available to support systematic assessment of infants' early vocal development. This study sought to develop and conduct a preliminary evaluation of the validity of a parent report tool designed for this purpose, the Vocal Development Landmarks Interview (VDLI). Method The participants were caregivers of 160 typically developing 6- to 21-month-old infants. Caregivers participated in the VDLI, which uses audio samples of authentic infant vocalizations to query parents regarding their children's vocal behaviors. The VDLI yields 3 subscale scores (Precanonical, Canonical, and Word) and a total score. Caregivers also completed sections of the Communication and Symbolic Behavior Scales Developmental Profile Caregiver Questionnaire that yielded a speech composite score. Results Cross-sectional analyses showed that the VDLI is sensitive to age and captures the expected developmental trajectories of vocal behaviors. A strong, positive correlation ( r = .93) was found between VDLI total scores and the Communication and Symbolic Behavior Scales Developmental Profile speech composite score, indicating concurrent validity. Subscales were found to be internally consistent. Conclusion Preliminary findings of sensitivity to age, concurrent validity, and internal consistency provide support for the eventual use of the VDLI as a clinical tool for tracking vocal and early verbal milestones. Future research will explore the level of concordance between parent report and researcher observations of child vocal behaviors. Supplemental Material https://doi.org/10.23641/asha.8330003.
