PurposeThis study aims to investigate the determinants of the extent and quality of corporate social responsibility disclosure (CSRD) in Jordan. The study examines a number of factors that influence the extent and quality of CSR disclosure, such as corporate characteristics, corporate governance and ownership structure.Design/methodology/approachA quantitative approach and a content analysis technique is used to measure the extent and quality of CSRD from annual reports. The sample is drawn from the annual reports of 118 Jordanian companies between 2010 and 2015. A CSRD index is constructed, which includes the disclosures of the following categories: environmental, human resources, product and consumers, and community involvement. This is the first study that presents a new measurement for CSR disclosure quality by using images and charts in a seven-point scale measurement.FindingsThe result reveals that the extent of CSRD is higher than quality in Jordan. Regarding the determinants of CSR disclosures, the following factors were found to have a significant relationship with both the extent and quality of CSRD: board size, non-executive directors, age of firm, foreign members on the board, number of boards meetings, the presence of audit committees, big 4, government ownership, size of firm and industry type. Non-executive directors was found to have a significant correlation with the extent of CSRD.Research limitations/implicationsThe current study has some limitations; first, the study findings are limited to the Jordanian environment. Second, the study adopted a purely quantitative method, and future research could include interviews and questionnaires to gather data from financial managers and chief executive officers (CEOs). Third, the potential influences on the level and quality of CSR are not limited to the variables tested in this study. Future research can be done on new determinants, such as CEO interlocking and profitability. Finally, the sample included companies from two main sectors – the services and industrial sectors; thus, this limited the results to these two main sectors.Practical implicationsPractitioners, as firms, should develop new strategies and ensure that CSR is included in their reports. Thus, companies can achieve legitimacy for their products and activities. Policymakers must consider introducing new laws that mandate CSRDs since it has many advantages for companies and society. In addition, this research suggests amending the law to require companies to have 33% of their directors be non-executives since this will remove the negative effect on CSR disclosure. Investors must pay attention to the social activities of the companies they invest in, as CSR could have a positive effect on their market value.Social implicationsThe study has indicated that Jordanian companies became increasingly more involved in CSR activities, as this growth in CSRD is linked with global increases in CSR. Moreover, the study has revealed that the highest category of CSR disclosures is related to products or services and employee information. On the other hand, the lowest category of CSR disclosures is related to community and other disclosures (extent) and environmental disclosures (quality). Furthermore, the results show that the services sector was found to have more disclosures regarding employees and community, whereas the industrial sector was more concerned about environmental and product information.Originality/valueTo the best of the authors’ knowledge, this is the first study that presents a new measurement for CSR disclosure quality by using images and charts in a seven-point scale measurement. This new seven-point scale will be adopted to distinguish between poor and excellent disclosures. In addition, to the best of the authors’ knowledge, this is the first study in Jordan which examines the determinants of the extent and the quality of CSR for three categories, namely, corporate characteristics, corporate governance and ownership structure.
