#### General Thoughts

You might want to consider a canonical correlation analysis in situations where you have:- a set of predictors of task/job performance (e.g., ability, personality, demographics) and a set of performance measures (e.g., speed, accuracy, etc.)
- two tests each with multiple scales that are meant to measure similar things (e.g., two measures of the Big 5 personality factors). This can be useful if you are trying to validate a newer measure against a pre-existing measure.
- a set of self-report measures and a set of behavioural measures (e.g., performance on a task)
- a set of set of brain scan measures and a set of behavioural measures

#### General References

The following references provide an overview of the technique.- Sherry and Henson (2005) provide an excellent gentle primer on canonical correlation. This is probably the best place to start. It also provides many useful references. PDF is available here
- G. David Garson provides an explanation of key terms and concepts
- Tabachnick and Fidell (1996) have a chapter written for researchers in psychology
- Magnus Borga presents a mathematical overview of canonical correlation. If you understand calculus and linear algebra, it is worth reading.

#### R

If you want to implement your analyses in R, the following may provide a useful starting point.- UCLA have a tutorial on canonical correlation in R.
- see the
`cancor`

function in base R;`canocor`

in the`calibrate`

package; and the`CCA`

package.

#### SPSS

If you want to use SPSS to run a canonical correlation, these tutorials may be useful.- G. David Garson provides an example of SPSS canonical correlation Output with interpretation.
- UCLA provide annotated SPSS Output for canonical correlation.

`CANCORR`

changes between versions and installations of SPSS. David Garson sets out the following code template:
INCLUDE 'c:\Program Files\SPSS\Canonical correlation.sps'. CANCORR SET1=varlist/ SET2=varlist/.In contrast on my installation, the script line needs to be:

INCLUDE 'C:\Program Files\SPSSInc\PASWStatistics18\Samples\English\Canonical correlation.sps'.To find the script on your installation, go to your SPSS installation and search for "canonical".

#### Journal Articles reporting Canonical Correlation Analysis

The following references provide examples of how to justify, present, and interpret the results of a canonical correlation analysis.- Rossier, Meyer and Berthoud (2004) [get pdf here] explore the commonalities between the NEO and 16PF personality inventories.
- Satterfield, Buelow, Lyddon, and Johnson (1995) look at the relationship between client expectations and attitude to change in a clinical psychology setting.
- Luthans, Welsh, and Taylor (1988) [get pdf here] present a canonical correlation relating a set of managerial effectiveness measures to a set of managerial activities.
