Table 4 Bivariate analyses of associations between continuous putative variables and total wait time

Continuous variables		Test (r_s)	p
Time spent on assessment (minutes)		0.31	0.02^a
Years in practice		−0.13	0.34
Categorical variables	Median wait time (months)	Test	p
Type of assessor		Kruskal-Wallis chi-squared = 3.66	0.16^a
Developmental pediatrician	6.5
General pediatrician	7.5
Other	3
Accepts referral from family doctor		Wilcoxon rank sum test W = 200	0.24
Yes	7
No	6
Practices in team		Wilcoxon rank sum test W = 308.5	0.25
Yes	9
No	6.5
Catchment		Kruskal-Wallis chi-squared = 2.85	0.42
Within city only	6.5
Within regional health authority	9
Within province/territory	6.5
No defined catchment	6.5
Province of practice		Kruskal-Wallis chi-squared = 13.67	0.19 ^a
British Columbia	9.5
Alberta	5
Ontario	6.5
Quebec	14.5
New Brunswick	8.5
Other^b	7.5

^aVariable meets cutoff of p < 0.2 to be included in regression analysis
^b“Other” is the median wait time for provinces with one respondent (Manitoba, Saskatchewan, Nova Scotia, Newfoundland and Labrador, Yukon, and Nunavut) that have been collapsed in the displayed results to prevent identification of individual respondents’ wait times
