Bien-être psychologique au travail et performance des équipes : une équipe heureuse est-elle performante ?

Abstract : In psychology, the concept of « well-being », a positive component of health (Keyes, 2003), has a long history of scientific investigation, positioning this concept at the crossroads of various issues: distinction between hedonist (Diener, 1999) and eudemonic (Ryff, 2014) conceptions, the presence of a specific psychological wellbeing at work (Dagenais-Desmarais, 2012), questionnaire assessment of individual and collective dimensions (Heutte, 2010), connection with team performance (Rousseau, Aubé & Savoie, 2006), multilevel approaches to health prevention at work (Martin 2015). We postulate that a questionnaire measuring simultaneously both one’s own personal well-being and that of one’s team, provides at the same time a reliable appreciation of these two dimensions and a reliable measurement of team effectiveness/performance. This can be achieved through a “double entry” questionnaire based on the « referent shift » method (Chan 1998). By clarifying the translation of psychological wellbeing at work from the individual to the group level, our research (embedded in CIFRE conventions) participates in preventing and accompanying health issues, through its original focus on working teams.Five studies involving 1101 active workers in corporate and French institution have shown that a process of social comparison does contribute to individual answers, with no impact on the psychometric quality of the of the measurement scales. This relationship individual/group, which juxtaposes affiliative vs differentiative needs (Codol, 1973, 1975a, 1975b, 1984; Brewer, 1991, 2007, 2012), helps operate a distancing between regards to one’s self and one’s team in the answers to the double entry questionnaire. These findings open the way to new analysis, based on forecasting team functioning. Moreover, this dissertation offers a new research perspectives into the multi-level measurement of health at work, and calls for complementary investigations on cognitive processes specific to the selected « matrix » method.
