Improving the Efficiency of the Bilingual Input-Output Survey-Home.
Article in American journal of speech-language pathology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThe Bilingual Input-Output Survey (BIOS)-Home (Peña et al., 2018) is used to provide speech-language pathologists (SLPs) with an estimate of children's exposure to two languages. The current hour-by-hour approach of the BIOS can be time consuming to administer and calculate. The current study seeks to improve the efficiency of the BIOS-Home by replicating Calandruccio et al.'s (2021) finding that the BIOS can be shortened by time periods around children's routines and extending these findings by preliminarily exploring the relationship of the shortened BIOS with results of a bilingual screener.
methodThe current study includes 1,337 Spanish-English bilingual children from two data sets. Children's ages ranged from 49 to 71 months (
resultsPCAs using the two data sets identified three time periods (morning, afternoon, and late afternoon/evening) for weekday receptive language and three time periods (morning, afternoon, and evening) for weekend receptive language. Language test score correlations comparing the hour-by-hour and the shortened approaches are highly similar, supporting the validity of the shortened approach.
conclusionConsolidating the BIOS-Home questionnaire is a viable approach that can save time and elicit valid information about children's bilingual input and output.
