Abstract
OBJECTIVE
While other models focus more on disease and pathophysiology, the biopsychosocial approach emphasises the importance of human health and disease in their fullest contexts. If we are to gain an insight into physical and psychological health needs, and address them quickly and adequately, it is important that we recognise them already at the family practice stage. An approach that assesses needs at patient level could also be seen as patient-centred care, which is one of the key elements of high-quality care. To the best of our knowledge, no scale for measuring the biopsychosocial approach of family physicians has yet been developed.
DESIGN
The aim of this study was to develop and validate a scale that measures the biopsychosocial approach of family physicians to their patients through the Delphi and validation process.
SETTING
The scale was developed through the Delphi study and validated by means of significant statistical methods. Pearson's correlation coefficient, Cronbach's alpha, the intracorrelation coefficient, the Spearman-Brown coefficient and exploratory factor analysis were applied.
PARTICIPANTS
Five family physicians took part in a brainstorming process and 24 family medicine experts took part in the Delphi study. For the first part of the validation process, there were 31 family medicine trainees in the first group and 32 in the second group. For the last part of the validation process, 164 family physicians completed the scale.
RESULT
Through the Delphi study, 39 final items covering three areas within the biopsychosocial approach were identified. Construct validity was high, with positive linear correlation and good face validity. The intraclass correlation coefficient for test-retest reliability was 0.862. The Spearman-Brown coefficient was the highest (0.931) on an even and odd division. Factor rotation showed that three factors on 35 items explained 39.5% of variances. The final internal consistency on 35 items was 0.911.
CONCLUSION
The developed scale measures the biopsychosocial dimension of family physicians' work with high Cronbach's alpha measures and good validity.
