Motivational drivers of heavy work investment: intercultural comparison between USA and Egypt

Purpose The purpose is to identify the underlying motives of heavy work investment (HWI) types (i.e. workaholism and work engagement) based on self-determination theory, while controlling for job demands and resources. The role of four cultural differences (i.e. individualism, power distance, uncertainty avoidance and masculinity) in moderating the motivational correlated relationships is also explored using data retrieved from two distinct cultures (i.e. the USA and Egypt).Design/methodology/approach Full-time employees (N = 595) in the USA and Egypt were surveyed. Multiple regression analyses were used to test the associations between the two HWI types and four types of motivation (i.e. intrinsic, extrinsic, introjected and identified motivations). Furthermore, moderation analyses were conducted to explore potential effects of four cultural dimensions (i.e. individualism, power distance, uncertainty avoidance and masculinity) on the motivationalcorrelated relationships.Findings Workaholism positively relates to the controlled types of motivation (i.e. extrinsic and introjected regulation), while work engagement positively relates to the autonomous ones (i.e. intrinsic and identified regulation) and negatively associates with extrinsic motivation. Moreover, cultural masculinity moderated the relationship between work engagement and extrinsic motivation, as well as the association between workaholism and extrinsic motivation.Practical implications A clear differentiation of motivation behind both types of HWI is required by occupational health practitioners to design interventions that stimulate employee engagement rather than fuel workaholism. Multinational organizations could also benefit from understanding the interaction between cultural dimensions, motives and HWI, thereby planning more effective work engagement strategies among different cultures.Originality/value This is the first study to investigate the motivational correlates of HWI types across two contrasting cultures.
