Multicenter Study
Development of a multidimensional measure for recurrent abdominal pain in children: population-based studies in three settings.
Recurrent abdominal pain (RAP) is a common problem in children and adolescents. Evaluation and treatment of children with RAP continue to challenge physicians because of the lack of a psychometrically sound measure for RAP. A major obstacle to progress in research on RAP has been the lack of a biological marker for RAP and the lack of a reliable and valid clinical measure for RAP. The objectives of this study were (1) to develop and test a multidimensional measure for RAP (MM-RAP) in children to serve as a primary outcome measure for clinical trials, (2) to evaluate the reliability of the measure and compare its responses across different populations, and (3) to examine the reliabilities of the measure scales in relation to the demographic variables of the studied population. ⋯ The MM-RAP demonstrated good reliability evidence in population samples. Children who have RAP and are seen at pediatric gastroenterology or primary care pediatric clinics have similar responses, showing that the measure performed well across several populations. Age did not affect the reliability of responses. The MM-RAP included 4 dimensions, each with several items that may identify disease-specific dimensions. In addition, dividing the nonpain symptoms scale into 2 components instead of 1 component could assist in creating a disease-specific measure. The present study focused exclusively on developing the multidimensional measure for RAP in children that could assist physicians in evaluating the efficacy of RAP treatment independent of psychological evaluations. In addition, the measure was designed for use in clinical trials that evaluate the efficacy of RAP treatment and to allow comparison between intervention studies. In conclusion, we were able to identify 4 dimensions of RAP in children (pain intensity, nonpain symptoms, pain disability, and satisfaction with health). We demonstrated that these dimensions can be measured in a reliable manner that is applicable to children who experience RAP in various settings.

Randomized Controlled Trial Multicenter Study Clinical Trial
Effect of pneumococcal vaccination on quality of life in children with recurrent acute otitis media: a randomized, controlled trial.
Limited effectiveness of current treatment strategies for recurrent acute otitis media (RAOM) and increasing antibiotic resistance have diverted attention to prevention of AOM by vaccination. Pneumococcal vaccination for AOM seems to have only modest clinical efficacy. Thus far, the effects on health-related quality of life (HRQoL) or functional health status (FHS) have not been studied. ⋯ Pneumococcal vaccination has no beneficial effect compared with control vaccination on either HRQoL or FHS in children 1 to 7 years old with RAOM.
