Do behavioural intentions matter? A diary study on work-related ICT-use after work hours

Because work-related ICT use after hours (WICT) has often been linked to negative outcomes, it is intriguing that many people still engage in this behaviour, often on a daily basis. Yet, qualitative research suggests that WICT may be less harmful when people consciously plan to engage in this behaviour. Drawing on Action-Regulation Theory, this paper tests the assumptions that WICT is sometimes a planned behaviour that people intend to engage in in response to work-related stimuli (e.g., daily unfinished tasks, daily workload) and that the outcomes of this behaviour are less detrimental when WICT is more intended or planned. We tested our hypotheses using a 5-day diary study (i.e., two measurement points a day) among 186 Flemish employees. We found that daily unfinished tasks - though not daily workload - were positively related to daily WICT via daily intentions to engage in WICT. Furthermore, daily intentions to engage in WICT were found to strengthen, rather than buffer, the negative relationship between daily WICT and psychological detachment. We found no moderation effect of daily intentions to engage in WICT in the relationship between WICT and work-to-home conflict. Implications for theory and practice are discussed.
