Description

The EORTC QLQ-C15-PAL is an abbreviated 15-item version of the EORTC QLQ-C30
(version 3.0) developed for palliative care.

The 15 items are:

q1 = Short walk

q2 = In bed

q3 = Need help

q4 = Short of breath

q5 = Pain

q6 = Trouble sleeping

q7 = Felt weak

q8 = Lacked appetite

q9 = Felt nauseated

q10 = Been constipated

q11 = Been tired

q12 = Pain interference

q13 = Felt tense

q14 = Felt depressed

q15 = Quality of life

Based on 15 variables where the first 14 are scored 1-4 (1='Not at all',
2='A little', 3='Quite a bit', and 4='Very much') and the fifteenth is scored
1-7 (1='Very poor' and 7='Excellent') qlqc15 calculates function scales,
symptom scales and single-item scales.
The scales are labeled in accordance with the descriptions for the QLQ-C15-PAL.

The shortened scales qlq_pf, qlq_ef, qlq_fa, and qlq_nv are scored using the
special QLQ-C15-PAL scoring while the remaining scales (qlq_ql2, qlq_pa, qlq_dy,
qlq_sl, qlq_ap, and qlq_co) are scored according to the original scoring
procedures described in the QLQ-C30 Scoring Manual.

Missing values or out of range input values are all handled as missings and
value based on these inputs are calulated.

Examples

Generating the 15 input variables (example data) in correct order:

`"clear"'
`"set obs 4"'
`"generate q1 = _n"'
`"generate q2 = q1"'
`"generate q3 = q1"'
`"fillin *"'
`"drop _fillin"'
`"generate q4 = q3 if _n < 5"'
`"generate q5 = q2 if _n < 17"'
`"generate q6 = q3 if _n < 5"'
`"generate q7 = q2 if _n < 17"'
`"generate q8 = q3 if _n < 5"'
`"generate q9 = q3 if _n < 5"'
`"generate q10 = q3 if _n < 5"'
`"generate q11 = q3 if _n < 17"'
`"generate q12 = q3 if _n < 17"'
`"generate q13 = q2 if _n < 17"'
`"generate q14 = q3 if _n < 17"'
`"generate q15 = _n if _n < 8"'

Run the command on the 15 input variables:

`"qlqc15 q*"'
