This is a cross-cultural study of organisations founded in positive psychology. The samples of 289 subjects are from South Africa (91) and Norway (198). The study is a tentative mapping of psychosocial factors related to work engagement where altruism was tested as a moderating factor. There were no significant differences on the general level of work engagement for the two countries, but relating to the three subscales there were two significant differences. Work absorption was higher in the South-African sample, and the Norwegian sample was higher on vigour. The South-African population was significant higher on altruism compared to the Norwegian population, but altruism showed no direct effect on work engagement. The psychosocial factors were shown to be a variable of predictive value of 49.9 % of the variance shown in work-engagement. The most contributing single psychosocial factors related to work-engagement were emotional load, social support, role-conflict and need for recovery. There were also found interacting effects on four of the psychosocial factors related to work engagement. Neither culture nor altruism was shown to have effect on the relation between psychosocial factors and work engagement
