To examine the psychometric properties of a revised scale, named 'observing patient involvement in decision making' (OPTION), by analysing its reapplication to sample routine primary care consultations. The OPTION instrument assesses what degree clinicians involve patients making.Cross-sectional assessment medical interaction two calibrated raters.Primary care.Twenty-one general practitioners provided 186 consultations for assessment.Observational score using instrument.Compared with first version scale that uses magnitude instead an attitude when applied same data set, resulted improvement scale's reliability and lower scores levels achieved practitioners. Factor analysis confirms it is acceptable regard as single construct. Although there moderate variability raters are assessed on item basis, agreements between at level overall high (the intraclass correlation coefficient total was 0.77), evaluation set per practitioner (e.g. 5 10 consultations), where aggregate would be used determining performance.We conclude sufficiently reliable formal whole (all 12 items).
