Nurses' representations of their work are defined as their cognitive '
work spaces', a theoretical concept derived from Newell & Simon's (197
7) problem-solving model and Lewin's (1935) concept of interacting pos
itive and negative valences, Using a structural equation modelling tec
hnique, a network of positive and negative features in nurses' work sp
aces is described in patterns of response to a questionnaire eliciting
nurses' ratings of their professional opportunities and difficulties,
The modelling technique revealed the dominance of positive over negat
ive features, and the overall significance of social recognition for e
ncouraging nurses to remain in nursing, Comparative analyses revealed
that dominant features of work space representations did not differ fo
r nurses from four city and country hospitals, nor in relation to posi
tions in the nursing hierarchy, The importance of understanding the pe
rceptions of nurses is discussed in relation to changes and developmen
t in nursing as a profession.
