Mixed-Effects Location-Scale Model for Affect and Physical Feeling State Variables and Mean Hourly Leisure-time Moderate-to-Vigorous Physical Activity (MVPA) in Minutes—Maximum Likelihood Estimates and Standard Errors

Positive Affect (PA)
Parameter	Mean β (SE)	p	BS var. α (SE)	p	WS var. τ (SE)	p
Intercept	1.74 (0.10)	<.001	−1.10 (0.15)	<.001	−0.48 (0.14)	.001
Mean hourly leisure-time MVPA	0.01 (0.03)	.621			−0.09 (0.04)	.018
BS var. in scale					0.42 (0.14)	.003
Covariance (mean and WS var)					−0.15 (0.06)	.009

Negative Affect (NA)
Parameter	Mean β (SE)	p	BS var. α (SE)	p	WS var. τ (SE)	p
Intercept	0.42 (0.05)	<.001	−2.44 (0.16)	< .001	−1.50 (0.09)	< .001
Mean hourly leisure-time MVPA	−0.03 (0.01)	.057			−0.06 (0.02)	.011
BS var. in scale					††	††
Covariance (mean and WS var)					††	††

Feeling energetic
Parameter	Mean β (SE)	p	BS var. α (SE)	p	WS var. τ (SE)	p
Intercept	1.32 (0.09)	<.001	−1.48 (0.16)	<.001	−0.19 (0.08)	.014
Mean hourly leisure-time MVPA	0.01 (0.02)	.535			−0.002(0.02)	.909
BS var. in scale					0.08 (0.03)	.011
Covariance (mean and WS var)					−0.01 (0.02)	.743

Feeling tired
Parameter	Mean β (SE)	p	BS var. α (SE)	p	WS var. τ (SE)	p
Intercept	0.82 (0.06)	<.001	−2.10 (0.17)	<.001	−0.56 (0.14)	<.001
Mean hourly leisure-time MVPA	−0.01 (0.02)	.687			−0.02(0.03)	.489
BS var. in scale					0.53 (0.13)	<.001
Covariance (mean and WS var)					0.20 (0.04)	<.001

Note. N = 119. BS = Between-subjects. WS = Within-subjects.

^††The model with the addition of the random scale estimate (BS var. in scale) and estimate of covariance between random scale and location (mean and WS var) did not converge due to a lack of variance in the dependent variable.
