Items are listed by construct.
"a seven-point Likert scale ranging from 'extremely disagree' to
'extremely agree' [was] chosen as the response format." (pages 198-199)
The PWS [personal work station] was defined in the instructions
accompanying the questionnaire as a set of computerized tools designed
for an individual.  It was indicated that the PWS "usually consists of a
personal or microcomputer with one or more software packages, such as a
word processing program or a spreadsheet, or a computer terminal hooked
up to a central mainframe computer again with the appropriate software."

a.  The indicated items were all deleted as the result of the first
factor analysis and hence were not in the final scales. 

b.  The indicated items, which were deleted after the initial test, are
suggested as candidates for inclusion in any expanded scale. 

c.  The indicated items, which were not in the final instrument, had
item-scale correlations less than 0.40 in the initial test and are
suggested as secondary candidates for lengthening the scale. 

d.  * indicates items suggested for inclusion in any "short" scales.
