Purpose
This paper aims to answer whether board attributes affect corporate social responsibility disclosure quality (CSRDQ) and whether these findings are sensitive to CSRDQ measurement.

Design/methodology/approach
The authors use the content analysis method to measure CSRDQ in annual report narratives of 41 Mauritian-listed companies for 2008–2019. System-generalized method of moments is used to test research hypotheses.

Findings
The analysis shows that board attributes affect CSRDQ. It also shows that the impact of CSRDQ is sensitive to CSRDQ measurement.

Practical implications
This study informs stakeholders on the drivers of CSRDQ. Mauritius authorities could revise the corporate governance code to enhance CSRDQ, and the Stock Exchange of Mauritius could also provide regulations/guidance to listed companies to improve their CSRDQ.

Originality/value
This study brings new insights by viewing CSRDQ based on verifiability, as verifiable CSR reporting improves the fairness of information disclosed by management.
