conditional compute syntax incorrect

[J McClure]

I am now calculating the score of a 9 item depression questionnaire
(PHQ-9). I have dichotomized the 9 questions into the variables
PHQ_tiredS, PHQ_sleepS,  PHQ_eatS, PHQ_concS, PHQ_badS,  PHQ_movemtS,
PHQ_anhedS,  PHQ_downS, and PHQ_deathS (0=no and 1=yes). The criteria
for the new variable ( MajDeprsn) to be positive (yes=1) is two part.
First either PHQ_anhedS or  PHQ_downS must be positive (=1) and then the
sum of all 9 variables must be 5 or greater. Results from this code are
all 482 cases=0. I think my parenthesis are wrong.  Thanks, Jan


Compute MajDeprsn=0.
  If (PHQ_anhedS=1 or PHQ_downS=1) and sum(PHQ_tiredS PHQ_sleepS
PHQ_eatS PHQ_concS PHQ_badS
   PHQ_movemtS PHQ_anhedS PHQ_downS PHQ_deathS) ge5   MajDeprsn=1.
  FREQUENCIES  MajDeprsn.

Aren't u forgetting the commas in between the operands for sum? Hope you are keeping a space between ge operator and the value 5. Put the EXECUTE command to execute.

If your variables are not contiguous in the file, try putting commas in between the variable names in your syntax.  Are you sure the commands start in column one?  They seem to be inset in your mail.

 

This needs breaking up so you can see what you are doing.  Do it step by step.  Start by counting the yes responses to all 9.  If I've understood you correctly, you should be able to copy and paste the syntax below.  If there are missing data you may need to do

 

compute index3 =

    sum.9 (PHQ_tiredS,  PHQ_sleepS, PHQ_eatS,PHQ_concS, PHQ_badS,  PHQ_movemtS,

                PHQ_anhedS,  PHQ_downS, PHQ_deathS ) .

 

John

 

count index1 = PHQ_tiredS, PHQ_sleepS,  PHQ_eatS, PHQ_concS, PHQ_badS, 

                            PHQ_movemtS, PHQ_anhedS,  PHQ_downS,  PHQ_deathS (1) .

 freq index1.

 

count index2 = PHQ_anhedS,  PHQ_downS (1) .

freq index2 .

cro index1 by index2 .

 

if ((index2 ge 5) and (index2 GE 1)) MajDeprsn = 1.

freq index1.
