Results of the final GLMM examining the effect of the test and control predictors on the number of intervals other types of affiliation was observed.

	Estimate	SE	Z	df	χ2	p–value

Intercept	−2.65	0.39	−6.74
Test predictors
Current condition (Continuous)^a	−0.39	0.17	−2.36	1	4.59	0.032
Experimental group (IC)^b	0.95	0.50	1.89	1	3.04	0.081
Control predictors
Previous relationship (Yes)^c	−0.62	0.45	−1.40	1	1.77	0.184
Pairing duration (Years)^d	−0.67	0.26	−2.56	1	5.21	0.022

Current condition was dummy coded with the ‘intermittent’ pair housing condition being the reference category.

Experimental group was dummy coded with the ‘CI’ experimental group being the reference category.

Previous relationship was dummy coded with ‘no’ previous relationship being the reference category.

Pairing duration (years) was log and z-transformed, original values ranged from 0.30 to 2.07 years, mean ± standard deviation: 0.90 ± 0.53 years.
