Using Multiple Regression in Outcome Studies

Merle Canfield

The following Syntax File prepares the data for analysis.

File Name = cmpdiff.sps

*get file = '\proeval\pashrt.sav'.

compute danxious=sanxious‑fanxious.

compute ddepress=sdepress‑fdepress.

compute dborderl=sborderl‑fborderl.

compute dshiz=sschiz‑fschiz.

compute ftotal=mean(fanxious, fdepress, fborderl, fschiz).

compute dtotal=stotal‑ftotal.

compute overall=(danxious*danx)+

(ddepress*ddep)+

(dborderl*dbordl)+

(dschiz*dschiz).

compute xtrtanx=((trtanx+1)/(chron+1)).

compute xtrtdep=((trtdep+1)/(chron+1)).

compute xtrtbord=((trtbord+1)/(chron+1)).

compute xtrtsch=((trtsch+1)/(chron+1)).

execute.

The following commands compute a change score.

compute danxious=fanxious‑sanxious.

compute ddepress=fdepress‑sdepress.

compute dborderl=fborderl‑sborderl.

compute dshiz=fschiz‑sschiz.

The following commands compute a difference score.

compute ftotal=mean(fanxious, fdepress, fborderl, fschiz).

compute dtotal=stotal‑ftotal.

The stotal score was previously computed.

The following command computes an overall score for each person based on diagnosis. The subtest depression score is used for depressed clients, the subtest for anxious is used for anxious clients, the borderline score is used for borderline clients, and the schizophrenia score is used for schizophrenics.

compute overall=(danxious*danx)+

(ddepress*ddep)+

(dborderl*dbordl)+

(dschiz*dschiz).

The following commands compute the interaction score between chronicity and treatment (see the handout on chronicity and interaction).

compute xtrtanx=((trtanx+1)/(chron+1)).

compute xtrtdep=((trtdep+1)/(chron+1)).

compute xtrtbord=((trtbord+1)/(chron+1)).

compute xtrtsch=((trtsch+1)/(chron+1)).

Compute a multiple regression in the following manner:

Click on Statistics

Click on Regression

Click on Linear

Select dtotal (the dependent measure in this instance)

Click on the ‘right delta’ for Dependent

Select trtdep, trtanx, trtbord, trtsch (independent measures)

Click on Statistics

Select Descriptives and Block Summary

Click on Continue

Click on Paste

Add ZPP and CHA to the Statistics command in the Syntax file

Put the name of the data file in the Syntax file

Save the Syntax file

Run the Syntax file

Syntax File = pasreg1.sps

*get file = '\proeval\pashrt.sav'.
