Overview
Instrument Name: Paediatric Pain Profile
Abbreviation: PPP
Points for Consideration:
None
Description of Tool:
The Paediatric Pain Profile (PPP) is a 20-item ObsRO developed to assess pain behaviour in children (ages 1-18) with severe to profound neurological impairment (i.e., physical and learning impairments). Parents are asked to describe their child's history of pain, baseline behaviour 'On a good day', and current pain problems including 'Most troublesome pain (Pain A)', 'Second most troublesome pain (Pain B)' and 'Third most troublesome pain (Pain C)', summary graph, ongoing pain assessments and assessment actions and outcomes on a 4-level scale "Not at all", "A little", "Quite a lot", "A great deal". Higher scores represent more severe pain.

Interrater reliability
- Correlation coefficient used: Intraclass Correlation. Reliability of the total PPP score was 0.74. Correlation between raters on total score was 0.75. Reliability for individual items varied from 0.14-0.76 (mean 0.51)
- Population/Disease: Children aged 1 to 18unable to communicate through speech or augmentative communication; n=111
Hunt A (2004)
- Correlation coefficient used: Intraclass Correlation and Pearson's r. Reliability for the total PPP score was 0.73. Correlations between parent and healthcare professional raters was 0.70 (p<0.001).
- Population/Disease: Children aged 1 to 18 unable to communicate through speech or augmentative communication; n=54
Hunt A (2004)
- Correlation coefficient used: Intraclass Correlation. Reliability for the total PPP score was 0.87 and 0.19- 0.84 (mean 0.64) for individual items
- Population/Disease: Children aged 1 to 18 unable to communicate through speech or augmentative communication who ad undergone short-acting analgesia; n=54

Validity
Concurrent validity (convergent, divergent):
Hunt A (2004)
- Correlation coefficient used: paired t-tests were used to investigate differences between the child's PPP scores 'at best' and when in pain; analysis of variance (ANOVA) for linear relationship was calculated to assess the relationship between the PPP score and VRS score; Cronbach's alpha to determine the extent to which all items in the scale measure the same construct.
- Measure: PPP; Verbal Rating Scale (VRS)
- Results:
Mean PPP score for children's most troublesome pain (Pain A) was greater (mean 31.3, SD 9.9) than children with less troublesome pain (Pain B) (mean 26.9, SD 10.9); scores were significanly higher than those for children at their best (mean 11.1, SD 6.3)
PPP scores for pain A and B increased in line with parents' evaluations of the pain on the VRS (p<0.001).
- Population/Disease: Children aged 1 to 18 unable to communicate through speech or augmentative communication; n=30
Hunt A (2007)
- Correlation coefficient used: Pearson's r
- Measures: Paediatric Pain Profile (PPP); Numerical Rating Scale (NRS)
- Results:
Rater's PPP percent scores and their NRS: 0.76-0.90 (p<0.001)
PPP scores across raters: 0.58-0.78 (p<0.001)
Average PPP percent score and NRS by each rater and average by parent and caregivers: 0.33-0.61 (p=0.002 to p<0.001)
PPP and NRS: 0.91
PPP and VRS: linear relationship (p<0.0001)
- Population/Disease: Children (mean age 9.6, SD 5.8) who experience pain; n=29
Hunt A (2007)
- Measure/Groups: PPP score; saliva cortisol concentration
- Correlation coefficient used: Pearson's r
- Results:
PPP score and saliva cortisol concentration: r=0.378-0.451 (not significant)
- Population/Disease: Children (mean age 9.6, SD 5.8) who experience pain; n=29
Known-group validity:
Hunt A (2007)
- Measure/Groups of patients: high-pain (n=19) and low-pain (n=10)
- A priori hypotheses: Children in the high-pain group would have higher PPP scores than the low-pain group
- Were hypotheses confirmed: Yes
- Results: PPP percent scores were significantly higher in the high pain group than the low-pain group (independent-sample t-test P=0.23-0.009)
- Population/Disease: Children (mean age 9.6, SD 5.8) who experience pain; n=29

Ability to Detect Change
Ability to detect change (Responsiveness):
Hunt A (2004)
- Method: Responsiveness to change in pain in a short-acting analgesic group (n=41) (before administration of analesics and at hourly intervals for four hours following administration of the analgesic) and responsiveness to change in pain in children following orthopaedic or gastrointestinal surgery (n=30) (before surgery, two-hourly on the first postoperative day, four-hourly on the second day and eight-hourly on postoperative days three and five) was assessed using paired-sample t-tests. Time under the time-analgesic effect curve (AUC effect was calculated for the PPP scores of each child.
- Results:
Mean PPP score pre-dose was significantly greater than all later assessments (paired-sample t-test, p<0.001).
Mean AUC-effect: 44.2 (SD 27.1); treatment resulted in reduction in PPP score by 50% or more in n=23 (68%) children and n=5 children (15%) had less than 30% reduction in pain.
Postoperative group
- Were hypotheses confirmed: No, average pain scores did not differ across postoperative days.
Population/Disease: Children aged 1-18 years unable to communicate through speech or augmentative communication; n=30
