	Odds ratio of GP detection (95% CI)

Factor	Crude	Adjusted^b
Consultation length, minutes	1.07 (0.99 to 1.15)	1.07 (0.95 to 1.21)

GPAQ communication	1.02 (1.00 to 1.04)	1.03 (1.00 to 1.06)

Current mental health problem
No	1.00	1.0
Yes	6.98 (3.41 to 14.27)	8.48 (2.01 to 35.72)

GHQ-12 score	1.37 (1.25 to 1.49)	1.34 (1.17 to 1.54)

Number of patient-reported problems
Single	1.00	1.0
Multiple	1.60 (0.90 to 2.84)	1.76 (0.48 to 6.40)

Emotional attribution (main problem)
Not emotional	1.00	1.0
Partly/entirely emotional	10.69 (4.13 to 27.67)	5.02 (1.58 to 15.97)
Patient–doctor depth of relationship	1.04 (1.00 to 1.08)	0.94 (0.87 to 1.02)

↵a Sample restricted to those patients whose GHQ-12 score identified them as having psychological distress.
↵b Odds ratio adjusted for other factors in the model. GHQ-12 = 12-item General Health Questionnaire. GPAQ = General Practice Assessment Questionnaire.
