In a random sample of 1524 consecutive consultations involving 30 Gene
ral Practitioners (GPs), a study was made of the relationship between
the GP's affective and instrumental behaviour and patient satisfaction
as well as patients' space in the consultation, both at consultation
and GP-level. In a subsample of 99 consultations with hypertensive pat
ients, an additional study was made of the relationship between the GP
's affective behaviour and the quality of care on three dimensions (te
chnical-medical, psychosocial and doctor-patient relationship). The GP
's affective behaviour was negatively correlated with some aspects of
his/her instrumental behaviour, in particular with technical-medical i
nterventions and prescriptions. On the other hand, the GP's affective
behaviour related positively to several measures indicating patients'
'space in the consultation' (consultation length, proportion of patien
t talk, patient influence on the diagnosis and the discussion of psych
osocial topics). As hypothesized, a positive relation between affectiv
e behaviour and all four outcome measures was found. In a series of mu
ltivariate analyses affective behaviour proved to be the strongest fac
tor in explaining patient satisfaction and quality of care. Dimensions
of instrumental behaviour did not explain these outcome measures exce
pt for referrals indicating decreasing patient satisfaction; whereas d
iscussion of psychosocial topics, consultation length and proportion o
f patient talk explained additional variance in some of the outcome me
asures. The implications of these findings for general practice as the
centre of the professional arena where health problems are encountere
d were discussed.
