Measures before lockdown refers to the values imputed at the beginning of the lockdown, while conditions after lockdown refers to the values observed afterwards.
The test compares the estimated values at the start of the lockdown with those observed afterwards. For each scale, the number of subjects that have worsened, improved or remained constant is reported.
There was no information regarding the value of the ABS variable after the lockdown for one of the study subjects. Therefore, that individual was not taken into consideration in the analysis of the ABS variable.
Bold values highlight parameters with statistically significant change.
SOCWD, Social withdrawal scale; ADLH, ADL hierarchy scale; IADLH, IADL hierarchy scale; COMM, Communication Scale; ABS, Aggressive Behavior scale; DRS, Depression Rating scale; CPS, Cognitive performance scale.
