87 Proactive Vitality Management, Work Engagement, and Creativity Weekly Survey All the items in the weekly survey were taken from validated scales, and were adjusted to the week-level. Participants could respond to the items on a scale ranging from 1 = totally disagree to 7 = totally agree. Week-level proactive vitality management was measured with the eight-item instrument developed by [masked, in press]. Research on the psychometric properties of this scale has provided ample evidence for its reliability and validity. Two survey studies (total N = 813) and two diary studies (total N = 379) among employees from various occupational sectors showed that proactive vitality management can be reliably measured (mean Cronbach’s alpha = .88) with eight items that load on one overall factor. Providing evidence for convergent validity, daily proactive vitality management was moderately strong and positively related to Fritz, Lam and Spreitzer’s (2011) measure of (work-related) strategies and micro-breaks. Moreover, proactive vitality management was positively related to relevant personal characteristics (e.g., proactive personality and self-insight) and showed moderately strong positive relationships with job crafting and relaxation. Furthermore, proactive vitality management was positively related to cognitive liveliness and (creative) work performance (criterion validity). Sample items are: “Last week, I tried to inspire myself”, “Last week, I motivated myself”, and “Last week, I made sure I felt energetic during my work”. In the present study, Cronbach’s alpha ranged from .76 to .88 over the five weeks. Week-level work engagement was measured with the week-level version (Bakker & Bal, 2010) of the nine-item Utrecht Work Engagement Scale (Schaufeli, Bakker, & Salanova, 2006). Sample items are: “Last week, at work, I felt bursting with energy”, and “Last week, I was enthusiastic about my work”. Cronbach’s alpha ranged from .91 to .94 over the five weeks. Week-level creativity was measured with Tierney, Farmer, and Graen’s (1999) nine-item employee creativity scale. Sample items are: “Last week, I demonstrated originality in my work”, and “Last week, I identified opportunities for new products/processes”. Cronbach’s alpha ranged from .93 to .95 over the five weeks. 4
