The boundaries between work and private life are gradually blurring. More and more employees are involved in work during leisure time through cognitions, emotions or behaviours, in both negative and positive ways. This so-called work-home integration (WHI) can, on the one hand, hampers the necessary recovery from work and result in strain but, on the other hand, also restores resources and result in beneficial outcomes. In order to enhance our understanding of WHI and capture all its different forms, we suggest a new conceptualisation and measure of WHI. We therefore developed and validated the Work-Home Integration Questionnaire (WHIQ) in English, German and Slovene simultaneously using two cross-sectional studies (Study 1: N = 848; Study 2: N = 555) and a two-wave longitudinal study with a time lag of 1 month (Study 3: N = 379). Confirmatory factor analysis confirmed a three-factor structure with (1) negative cognitive-affective involvement, (2) positive cognitive-affective involvement and (3) behavioural involvement. Moreover, the WHIQ showed measurement invariance across the three languages and the results provide evidence for convergent, discriminant and incremental validity. Overall, the WHIQ is a reliable, valid and short measure to assess the extent to which employees are involved in work during leisure time.
