“…The SIS is developed according to Parten's (1932) scheme, which was tested for the validity to determine the levels of social interactions and established the psychometric properties ( Bakeman & Brownlee, 1980 ; Bakeman & Gottman, 1997 ). Even though Parten's scheme was originally applied to children, it has been evaluated as a valid coding scheme for assessing social interaction for different age groups ( Charko et al, 2016 ; Coplan et al, 2015 ) and in different settings including urban open space ( Donohue, 2015 ; Loebach et al, 2020 ). To verify the psychometric utility of SOSIP, a parallel-forms of reliability test was conducted to demonstrate the internal consistency of the protocol.…”
