# Making an existing questionnaire usable across languages

A multilingual web interface for the existing QCAE questionnaire, with keyboard navigation, local scoring and JSON/CSV export. I define requirements, maintain UI terminology and language-version provenance, and test functionality.

## Interface and personal contribution

I created and maintain a web interface for the existing Questionnaire of Cognitive and Affective Empathy. My work covers requirements, interaction design, keyboard navigation, local scoring, JSON/CSV export and functional checks, using AI-assisted implementation. The source repository identifies the instrument and the publications used for questionnaire variants.

## Localisation and terminology

I maintain a [UI terminology glossary](https://github.com/mariomarcolongo/Questionnaire-of-Cognitive-and-Affective-Empathy-QCAE-online-questionnaire/blob/d2d96ba3fa90af324a7b5f0a8c24d0b7b332829d/docs/LOCALIZATION.md) and check interface wording, language selection and questionnaire variants against their source publications. Language-version provenance is retained so readers can distinguish the interface translation from the questionnaire wording and its underlying evidence.

## Testing and scope

I inspect the rendered interface, keyboard behavior, scoring and exported files, and review changes against the requirements. Published questionnaire versions retain their source references; this interface work does not constitute a new psychometric validation.
