A visual analogue scale (VAS) and a 4-point scale (FPS) have been compared in patients suffering from prolonged constant pain due to chronic inflammatory or degenerative arthropathy. Each patient was treated with a constant low or high dose of paracetamol or dihydrocodeine throughout a four week period. The VAS was accurate, as reliable and more sensitive than the FPS in registering the intensity of chronic pain. Separate records of each estimate, sealed immediately on completion by the patient, resulted in omission of significantly more pain recordings on the FPS, whereas retention by the patients of their previous records did not systematically influence subsequent judgments. In this study, the VAS appeared to be more satisfactory than the FPS for patient self-rating of pain intensity.

In the treatment of patients with pain, measures related to (pain) behaviour are of major importance. Ambulatory activity monitoring can be used to obtain insight into actual behaviour. This study was designed to validate the Activity Monitor (AM), an instrument based on long-term ambulatory monitoring of accelerometer signals, to assess several physical activities during normal daily life. Ten failed back surgery (FBS) patients performed a number of functional activities in and around their own houses. During the measurements, continuous ambulatory registrations of accelerometer signals were made, based on four body-mounted accelerometers (one on each upper leg, two on the trunk). Video recordings made simultaneously with the measurements were used as a reference. The continuous output of the AM (postures, transitions, dynamic activities) was compared with visual analysis of the videotapes. The overall results showed an agreement between AM output and video analysis of 87% (inter subject range: 83-88%). The maximal error in the determination of the duration of activities was 0.3%. The overall number of dynamic periods was determined well (AM: 359; video: 368), while the number of transitions was slightly overestimated (AM: 228; video: 205). The results when using the three-sensor version of the AM were somewhat less accurate (overall agreement from 87% to 82%). The AM appeared to be a valid instrument to quantify aspects of behaviour of FPS patients, such as duration of activities and number of transitions. This new technique of ambulatory measurement of mobility activities seems to be a relevant and promising extension of the techniques currently used in the evaluation of pain treatment.

The Faces Pain Scale (FPS; Bieri et al., Pain 41 (1990) 139) is a self-report measure used to assess the intensity of children's pain. Three studies were carried out to revise the original scale and validate the adapted version. In the first phase, the FPS was revised from its original seven faces to six, while maintaining its desirable psychometric properties, in order to make it compatible in scoring with other self-rating and observational scales which use a common metric (0-5 or 0-10). Using a computer-animated version of the FPS developed by Champion and colleagues (Sydney Animated Facial Expressions Scale), psychophysical methods were applied to identify four faces representing equal intervals between the scale values representing least pain and most pain. In the second phase, children used the new six-face Faces Pain Scale-Revised (FPS-R) to rate the intensity of pain from ear piercing. Its validity is supported by a strong positive correlation (r=0.93, N=76) with a visual analogue scale (VAS) measure in children aged 5-12 years. In the third phase, a clinical sample of pediatric inpatients aged 4-12 years used the FPS-R and a VAS or the colored analogue scale (CAS) to rate pain during hospitalization for surgical and non-surgical painful conditions. The validity of the FPS-R was further supported by strong positive correlations with the VAS (r=0.92, N=45) and the CAS (r=0.84, N=45) in this clinical sample. Most children in all age groups including the youngest were able to use the FPS-R in a manner that was consistent with the other measures. There were no significant differences between the means on the FPS-R and either of the analogue scales. The FPS-R is shown to be appropriate for use in assessment of the intensity of children's acute pain from age 4 or 5 onward. It has the advantage of being suitable for use with the most widely used metric for scoring (0-10), and conforms closely to a linear interval scale.

This study examined experimentally the effectiveness of preparatory information provided by parents in creating accurate expectations and reducing children's procedural pain. Ear piercing was used as an analogue to minor painful medical procedures. Sixty children, aged 5-12 years, requesting ear piercing and accompanied by their parents, were randomly assigned to a parental information or contact-control condition. Parents in the information group were asked to read their child a description of the procedures and sensations of ear piercing. Parents in the contact-control condition played picture games for the same amount of time. Expected pain was measured on a visual analogue scale (VAS) and the Faces Pain Scale-Revised (FPS-R) before and after the parental information or contact-control procedure. Experienced pain was measured on the same two scales immediately after the ear piercing. Prepared children had more accurate expectations and reported significantly less pain (M=27.3) than non-prepared children (M=49.8). The validity of the measures was supported by strong correlations (r=0.87 to 0.96) between the VAS and FPS-R. The findings suggest that parental provision of preparatory information creates accurate expectations and reduces pain for children.

The main objective of this research was to determine the initial psychometric properties of the Faces Pain Scale - Revised (FPS-R) as a measure of pain intensity for use with Catalan children and adolescents. Results of the Catalan version of this scale (FPS-R-C) are similar to those obtained with the original instrument. In order to assess the validity and reliability of the FPS-R-C, two different samples were studied. The first sample contained 124 hospitalized children and adolescents (mean age 10.86; SD 2.5). They were asked to rate their affective state on the Faces Affective Scale (FAS) and the intensity of their pain on the FPS-R-C and the Coloured Analogue Scale (CAS). The pain intensity ratings reported with FPS-R-C and CAS were very similar, correlations ranging from 0.83 to 0.9. The relationship between the intensity of pain experienced and children's affective state was also statistically significant (R = 32, P < 0.01). The second sample contained 247 schoolchildren (mean age 9.43; SD 1.55), who were asked to imagine themselves in eight hypothetical painful situations and rate the degree of pain using the FPS-R-C and the CAS (correlations ranging from 0.83 to 0.96). Test-retest correlations on this questionnaire (Painful Events Inventory) ranged from 0.26 to 0.70. Overall, these results provide preliminary evidence of the reliability, and convergent and criterion-related validity of the FPS-R-C. Moreover, all participating subjects were asked to choose the pain scale they preferred the most. Our data suggest that, regardless of their age and/or gender, the subjects prefer the FPS-R-C to the CAS.

Accurate pain assessment is the foundation for effective pain management in children. At present, there is no clear consensus regarding the age at which young children are able to appropriately use self-report scales for pain. This study examined young children's ability to use the Faces Pain Scale-Revised; (FPS-R; [Hicks CL, von Baeyer CL, Spafford PA, van Korlaar I, Goodenough B. The Faces Pain Scale-Revised: toward a common metric in pediatric pain measurement. Pain 2001; 93: 173-83]) for pain in response to vignettes and investigated the role of developmental factors in predicting their ability to use the scale. One hundred and twelve healthy children (3-6 years old) were assessed for their ability to accurately use a common faces scale to rate pain in hypothetical vignettes depicting pain scenarios common in childhood. Accuracy was determined by considering whether children's judgements of pain severity matched the pain severity depicted in the various vignettes. Children were also administered measures of numerical reasoning, language, and overall cognitive development. Results indicated that 5- and 6-year-old children were significantly more accurate in their use of the FPS-R in response to the vignettes than 4-year-old children, who in turn were significantly more accurate than 3-year-old children. However, over half of the 6-year-olds demonstrated difficulties using the FPS-R in response to the vignettes. Child age was the only significant predictor of children's ability to use the scale in response to the vignettes. Thus, a substantial number of young children experienced difficulties using the FPS-R when rating pain in hypothetical vignettes, although the ability to use the scale did improve with age.

The purpose of this study was to determine the reliability and validity of selected pain intensity scales including the Faces Pain Scale Revised (FPS-R), Verbal Descriptor Scale (VDS), Numeric Rating Scale (NRS), and Iowa Pain Thermometer (IPT) with a cognitively impaired minority sample. A descriptive correlational design was used, and a convenience sample of 68 participants, admitted to acute care facilities in the South, with an average Mini Mental Status Exam score of 23 comprised the sample. Thirty-two percent of the participants were males, and 68% were females. The majority (74%) of the sample consisted of African-American participants with the exception that 16% were Hispanic and 10% were Asian. An overwhelming majority of participants were able to use all of the tools. Concurrent validity was supported with correlations ranging from 0.56 to 0.90. The lowest correlations were found between the FPS-R and the other scales, suggesting that the FPS-R may be measuring a broader construct incorporating pain. Test-retest reliability was supported with coefficients ranging from 0.77 to 0.89. In terms of pain scale preference, the Numeric Rating Scale (33%) was the preferred scale in the cognitively intact group and the FPS-R (54%) was the preferred scale in the cognitively impaired group. When race and cognitive status were considered, African-Americans and Hispanics preferred the FPS-R. Severely, moderately, and mildly impaired participants also preferred the FPS-R. The findings of this study support the use of these scales with older cognitively impaired minority adults.

This study examined pain and distress from needles in children undergoing blood sampling as a function of adult-child interaction and type of venous access (i.e., central external venous lines, internalized ports, or peripheral access via venipuncture). Participants were 55 pediatric oncology patients, aged 3-18 years, who were undergoing routine blood work. Pain ratings were obtained using the Faces Pain Scale-Revised (FPS-R) and conversation during the procedure was audio taped for coding using the Child-Adult Medical Procedure Interaction Scale-Revised (CAMPIS-R). Children's ratings of pain using the FPS-R were similar in the port (M=2.57/10, standard deviation [SD]=3.46) and peripheral (M=2.56/10, SD=3.24) groups, despite the fact that most children with internal ports were given a topical anesthetic. Similarly, there were no differences between port and peripheral groups in rates of child coping or distress, or parent and nurse observations of child pain. As would be expected, external line access was not associated with pain or distress, even among very young children, suggesting that they appropriately understood the pain rating scale. Results of the transcribed CAMPIS-R data indicate that the influences in adult-child interaction are bidirectional. Support was found for the well-established positive relationship between child distress and adult reassurance and empathy. Implications for intervention and selection of central venous access devices are discussed.

The purpose of this study was to improve the evaluation process of children with type I Osteogenesis Imperfecta (OI) by providing a quantitative comparison of gait and selected functional assessments to age-matched controls. A 14-camera Vicon Motion Analysis System was used for gait analysis along with selected functional assessments (Pediatric Outcomes Data Collection Instrument [PODCI], Functional Assessment Questionnaire [FAQ], Faces Pain Scale-Revised [FPS-R]) conducted on 10 subjects with type I OI and 22 age-matched healthy controls. The results of the OI group demonstrated abnormal gait parameters including increased double support, delayed foot off, reduced ankle range of motion and plantarflexion during third rocker, along with greater ankle power absorption during terminal stance and reduced ankle power generation during push off. The functional assessment scores of the OI group were similar to the control group for basic mobility and function, but were lower than their peers in the sports and physical function category. The evaluation of individuals with OI by means of gait analysis and selected functional assessments, along with an accurate biomechanical model of the lower extremities, is proposed to better understand and predict OI disability and improve quality of life.

Despite wide usage of the Numerical Rating Scale (NRS) for self-report of pain intensity in clinical practice with children and adolescents, validation data are lacking. We present here three datasets from studies in which the NRS was used together with another self-report scale. Study A compared post-operative pain ratings on the NRS with scores on the Faces Pain Scale-Revised (FPS-R) in 69 children age 7-17 years who had undergone a variety of surgical procedures. Study B compared post-operative pain ratings on the NRS with scores on the Visual Analogue Scale (VAS) in 29 children age 9-17 years who had undergone pectus excavatum repair. Study C compared ratings of remembered immunization pain in 236 children who comprised an NRS group and a sex- and age-matched VAS group. Correlations of the NRS with the FPS-R and VAS were r=0.87 and 0.89 in Studies A and B, respectively. In Study C, the distributions of scores on the NRS and VAS were very similar except that scores closest to the no pain anchor were more likely to be selected on the VAS than the NRS. The NRS can be considered functionally equivalent to the VAS and FPS-R except for very mild pain (<1/10). We conclude that use of the NRS is tentatively supported for clinical practice with children of 8years and older, and we recommend further research on the lower age limit and on standardized age-appropriate anchors and instructions for this scale.
