1 · What the graph read from it

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.

2 · The registry

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 Participation and Activity Inventory for Children and Youth 3-6 years (PAI-CY 3-6) was recently developed to assess the participation needs of children with visual impairment (VI) by means of parent-proxy report. This study reports on its psychometric properties.

methodsParents of children aged 3-6 years registered at two low vision rehabilitation centers in the Netherlands were invited to participate and completed the 52-item PAI-CY. Satisfaction with the PAI-CY 3-6 was determined using an evaluation form. Basic item analyses was conducted, after which an item response theory (IRT) model (i.e. the graded response model, GRM) was fitted. Deletion of items was informed by results of item analyses, fulfillment of IRT assumptions, differential item functioning, fit to the GRM and item information content. Face and content validity were considered; professionals from low vision rehabilitation centers were asked for their opinion in the item deletion process. After obtaining a satisfactory set of items, known-group validity, concurrent validity and test-retest reliability were also investigated.

resultsData of 237 parents were included in the analyses. Various aspects of the PAI-CY 3-6 were perceived as neutral to positive by over 85% of the respondents. After removing 17 items, the remaining 35 items reflected satisfactory fit to the GRM. Known-group validity was supported, since participants with more severe VI and comorbidity scored significantly worse than those with less severe VI and without comorbidity after correcting for potential confounders. Test-retest reliability was adequate, and the PAI-CY showed to have good concurrent validity. Feedback from professionals motivated the maintenance of 3 of the 17 deleted items, although not included in the scoring. Furthermore, two new items were added, resulting in a 40-item instrument.

conclusionsThe PAI-CY 3-6 has sound psychometric properties and can now be used to assess the participation needs of children aged 3-6 years with VI by means of proxy. Implementation in routine low vision rehabilitation care enables further optimization and investigation of its acceptability and feasibility.
