TL;DR

ValiText is a unified validation framework for computational text-based measures of social constructs, grounded in social science validity theory and empirical review. It guides researchers to establish substantive, structural, and external validation evidence through a checklist and documentation sheets, enhancing rigor and consistency in measuring abstract social concepts from text.

ABSTRACT

Guidance on how to validate computational text-based measures of social constructs is fragmented. While researchers generally acknowledge the importance of validating text-based measures, they often lack a shared vocabulary and a unified framework to do so. This paper introduces ValiText, a new validation framework designed to assist scholars in validly measuring social constructs in textual data. The framework is built on a conceptual foundation of validity in the social sciences, strengthened by an empirical review of validation practices in the social sciences and consultations with experts. Ultimately, ValiText prescribes researchers to demonstrate three types of validation evidence: substantive evidence (outlining the theoretical underpinning of the measure), structural evidence (examining the properties of the text model and its output) and external evidence (testing for how the measure relates to independent information). The framework is further supplemented by a checklist of validation steps, offering practical guidance in the form of documentation sheets that guide researchers in the validation process.

Motivation & Objective

• To address the fragmented and inconsistent validation practices in computational text-based measures of social constructs.
• To provide a shared vocabulary and structured approach for validating text-based measures in social science research.
• To strengthen methodological rigor by integrating validity theory from the social sciences with empirical validation practices.
• To support researchers in systematically documenting and justifying their validation processes through standardized tools.
• To promote transparency, reproducibility, and defensibility in measuring abstract social constructs from textual data.

Proposed method

• The framework is built on the threefold validity model from social sciences: substantive, structural, and external evidence.
• It integrates insights from an empirical review of validation practices in social science research.
• It incorporates expert consultations to ensure methodological soundness and practical applicability.
• It introduces a standardized checklist of validation steps to guide researchers through each phase of the validation process.
• It provides documentation sheets to help researchers record and justify validation decisions systematically.
• The framework is designed to be adaptable across diverse social constructs and text analysis methods.

Experimental results

Research questions

• RQ1 How can researchers systematically validate computational text-based measures of social constructs in a way that ensures methodological rigor?
• RQ2 What core components of validity—substantive, structural, and external—should be addressed when measuring abstract social constructs from text?
• RQ3 How can a unified framework improve consistency and transparency in validation practices across different research domains?
• RQ4 What practical tools can support researchers in documenting and justifying validation evidence throughout the measurement process?
• RQ5 How can validation frameworks be designed to be both theoretically grounded and practically actionable for researchers in computational social science.

Key findings

• ValiText provides a comprehensive, theory-grounded framework that integrates substantive, structural, and external validation evidence for text-based measures.
• The framework is supported by a practical checklist and documentation sheets that enhance transparency and reproducibility in validation processes.
• Empirical review and expert consultation validated the framework’s alignment with established social science validation principles.
• The framework enables researchers to systematically justify their measures, reducing ad hoc validation practices.
• By standardizing validation steps, ValiText supports more defensible and comparable research across computational text analysis applications.
• The framework is designed to be extensible and applicable across diverse social constructs and NLP methodologies.
