Title: Job performance

Sourc: Lawler (1967)

Description: Correlations among nine items concerning job satisfaction.
The items assess three performance criteria (T1 to T3) by three
different methods (M1 to M3). Such a matrix is called a
multitrait-multimethod matrix. The performance criteria are:

T1 = quality of job performance
T2 = ability to perform the job
T3 = effort put forth on the job

The three methods are: 

M1 = superior ratings
M2 = peer ratings
M3 = self ratings

The nine items are combined in the following way:

T1M1
T2M1
T3M1
T1M2
T2M2
T3M2
T1M3
T2M3
T3M3
