Table 1

Quality criteria and specifications.

Requirements to satisfy this criterion: satisfied if

Quality of measure selection
(i) Is the tool age appropriate?(i) VAS used for children 7 and above
(ii) NRS used for children 8 and above
(iii) FPS used for children 4 and above

(ii) Were children screened for developmental delay or was a measure of competency conducted prior to pain assessment?(i) Studies commented upon completing an assessment for delay prior to conducting the study
(ii) They excluded children with developmental delay (assumed they had assessed for this in order to do so)

Quality of measure administration
(i) Did the child have a chance to become familiar with the pain scale used, for example, by rating hypothetical scenarios?(i) Authors commented upon conducting an assessment of pain prior to the assessment used in the final analysis
(ii) Authors explicitly commented upon children and adolescents having time to practice or become familiar with the assessment

(ii) Did authors identify whether pain measurement captured provoked pain levels or pain levels at rest?(i) Authors specify the nature of the pain measurement captured; for example, do authors comment upon whether pain assessment encompasses pain levels in provoked situations (activity) or unprovoked ones (at rest)?

(iii) Was the child the main reporter of pain at assessment?(i) Authors explicitly stated that children completed the scale or questionnaire independently
(ii) Pain information was gathered as part of a clinical interview with the child or adolescent

(iv) Were successive pain ratings observed?(i) Authors described taking more than one assessment of pain

(v) Were consistent verbal anchors used across patients in the same study?(i) Authors described the anchors used

Quality of measure interpretation
(i) Was a narrative explanation of pain scores also obtained, at least at the first data collection point?(i) Authors explicitly stated that a narrative was gained as part of the pain assessment
(ii) Pain assessment was conducted as part of a clinical interview

Quality of measure reporting
(i) Was the temporal frame for pain ratings reported?(i) Authors state the time scale used to frame pain assessments

(ii) Were the authors clear about which type of pain was measured?(i) Authors describe the type of pain reported, for example, worst, least, and most pain
