ABSTRACT
Although workplace incivility (WI) has been extensively studied, limited attention has been paid to its validation in culturally diverse contexts such as China and Pakistan. Addressing this gap, the present study examines the psychometric properties of the instigated WI scale within these two distinct cultural settings. Furthermore, it investigates the cross-cultural measurement equivalence of the scale using a daily diary methodology. Participants were full-time employees from service-sector organisations in China (n = 110) and Pakistan (n = 118), recruited through snowball sampling. Over 10 days, 758 daily observations were collected from Chinese employees and 836 from Pakistani employees. The findings provide evidence supporting the validity and reliability of the scale in both samples, affirming the conceptual transferability of WI across these cultural contexts. The study also highlights the importance of accounting for cultural nuances in the manifestation and assessment of incivility. Establishing the scale’s validity and equivalence contributes critical methodological groundwork for future cross-cultural research on workplace mistreatment.
