Estimates of the extent of mental health problems and addictive behaviours, including gambling problems (n = 1058)

	n	%	95% CI
Gambling
PGSI ≥5	10	0.9	0.5 to 1.8
PGSI 1–4	45	4.3	3.2 to 5.7
Problems in the family with gambling	73	7.2	5.7 to 9.0
Mental health/addictive behaviours
Depression (Whooley ≥1)	561	55.8	52.7 to 58.9
Anxiety (GAD-2 ≥2)	262	27.0	24.3 to 30.0
Alcohol (AUDIT-C ≥5)	307	32.4	29.4 to 35.5
Drug use (SISQ)	140	14.3	12.2 to 16.7
PGSI ≥1 across practice characteristics
High deprivation (k = 4, n = 380)	23	6.1	4.0 to 9.1
Moderate deprivation (k = 3, n = 331)	13	3.9	2.2 to 6.8
Low deprivation (k = 2, n = 184)	6	3.3	1.3 to 7.3
Student health service (k = 1, n = 163)	13	8.0	4.5 to 13.5

PGSI = Problem Gambling Severity Index. Whooley = Whooley depression scale. GAD-2 = 2-item GAD scale for anxiety. AUDIT-C = 3-item consumption scale from the AUDIT. SISQ = Single-Item Screening Question for Unhealthy Drug Use. k = number of practices. For the purposes of these analyses the clinic was combined for patients who are homeless with the highly-deprived practices (thus k = 5).
