Difficulties in Activities:
Perceived Difficulty in General Performance:
Raw Constructs / Aggregates Created in BASE

 In the Yesterday Interview, for each activity mentioned, participants were asked whether

(a) the activity caused them any difficulty (difficulty),
(b) they used any aids (means), or
(c) anybody helped them (help).

For the activities which did or did not cause the participants any difficulty, which required aids and / or the help of others, the following variables were aggregated:

(a) the total length in minutes (minutes)
(b) the number of activities (frequency), and
(c) the percentage of time (of the total waking hours of the participant in question) (percent).

Several constructs were made from these aggregated variables.

 

Difficulty, Means, Help in Performance

(in general)

Note:
According to the design, construct names for Time 1 have the prefix q1,
names for Time 3 have the prefix q3, and names for Time 4 have the prefix q4.
