Feasibility, reliability and validity of the Thai version of the Pediatric Quality of Life Inventory 3.0 cerebral palsy module

Background

Quality of Life (QOL) and Health-related Quality of Life (HRQOL) are now considered as necessary outcome measures for children with cerebral palsy (CP). Various reliable and valid condition-specific HRQOL tools are available for these children. One of these is Pediatric Quality of Life Inventory (PedsQL) 3.0 CP module which has been widely used and was translated to many languages. As no Thai version is available, the authors have completed this translation.

Purpose

This study then aimed to investigate psychometric properties of the newly translated Thai PedsQL 3.0 CP module and to establish parent confidence in their ratings in the translated tool.

Methods

Translation of the PedsQL 3.0 CP module was performed based on linguistic translation guidelines. Then, the psychometric properties of the Thai version were established. PedsQL 3.0 CP module was completed by children with CP and their parents or caregivers twice with 2–4 weeks.

Results

Respondents were 97 parents or caregivers and 54 children. Minimal missing data were found. Acceptable internal consistency was supported except for Movement and Balance Scale (self-report). Intraclass correlation coefficients for parent proxy and self-report were good to excellent (0.684–0.950).

Conclusions

The feasibility, reliability and validity of the translated tool were supported.

Reliability and validity of the Pediatric Quality of Life Inventory™ (PedsQL™) Short Form 15 Generic Core Scales in Japan

Objective To assess the reliability and validity of the Japanese translation version of the Pediatric Quality of Life Inventory™ 4.0 Short Form 15 (PedsQL™ 4.0 SF15). Methods The PedsQL™ 4.0 SF15 was administered to 229 schoolchildren aged 6–13 years and 100 pediatric outpatients aged 5–18 years and their parents. Results Internal consistency reliability exceeded 0.70 for both proxy-reported and self-reported scales. Test–retest reliability demonstrated large values for parent proxy-report (range: 0.68–0.79) and moderate to large values for child self-report (range: 0.46–0.73). Parent proxy-report health-related quality of life (HRQOL) was higher than child self-report in all scales except for School Functioning. The correlations between the reports of the parents and children were moderate to high. Gender differences were observed in Social Functioning, School Functioning, and Psychosocial Health Summary, with girls reporting higher HRQOL than boys. Factor analysis indicated that four factors were extracted from the PedsQL™ 4.0 SF15 and these four factors corresponded mainly to the four scales. Known groups validity was established for proxy-report and self-report with higher HRQOL being reported for healthy children than those with psychosomatic complaints including headache and abdominal pain. Conclusion The Japanese translation version of the PedsQL™ 4.0 SF15 demonstrates good reliability and validity and could be used as a measure of HRQOL for transcultural comparisons of pediatric research in school settings and healthcare services research.

Rasch Analysis of the Pediatric Quality of Life Inventory 4.0 Generic Core Scales Administered to Patients With Duchenne Muscular Dystrophy

ObjectivesThe objective of this study was to examine the psychometric properties of the Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL 4.0 GCS) in Duchenne muscular dystrophy (DMD), a rare, severely debilitating, and ultimately fatal neuromuscular disease.MethodsPatients with DMD were recruited from 20 centers across 9 countries as part of the Cooperative International Neuromuscular Research Group Duchenne Natural History Study (NCT00468832). The psychometric properties of the PedsQL 4.0 GCS were examined using Rasch analysis.ResultsIn total, 329 patients with DMD (mean age 9 years, range 3–18 years, 75% ambulatory) completed the PedsQL 4.0 GCS. The most difficult instrument items, expressing the greatest loss in health-related quality of life, were those associated with emotional well-being (eg, being teased by other children, feeling sad, and not making friends), as opposed to somatic disability (eg, lifting heavy objects, participating in sports, and running). The mean item and person fit residuals were estimated at 0.301 (SD: 1.385) and −0.255 (1.504), respectively. In total, 87% (20 of 23) of items displayed disordered thresholds, and many exhibited nontrivial dependency. The overall item-trait interaction χ² value was 178 (115 degrees of freedom, P<.001). Our analysis also revealed significant issues with differential item functioning, and by investigating residual principal component loadings, the PedsQL 4.0 GCS total score was found to be multidimensional.ConclusionsThe PedsQL 4.0 GCS records information clinically relevant to patients with DMD, but the total scale score may not be fit for purpose as a measure health-related quality of life in this disease population.

Reliability and validity of the German version of the OPTION scale

Objective To examine the psychometric properties of the German version of the ‘observing patient involvement’ scale (OPTION) by analysing video recordings of primary care consultations dealing with counselling in cardiovascular prevention. Design Cross‐sectional assessment of physician–patient interaction by two rater pairs and two experts in shared decision making (SDM). Setting  Primary care. Participants Fifteen general practitioners provided 40 videographed consultations. Measurements Video ratings using the OPTION instrument. Results Mean differences on item level between the four raters were quite large. Most items were skewed towards minimal levels of shared decision making. Measures of inter‐rater association showed low to moderate associations on item level and high associations on total score level. Cronbach‐α of the whole scale based on the data of all four raters is 0.90 and therefore on a high level. An oblique factor analysis revealed two factors, but both factors were highly correlated so we can confirm a one‐dimensional structure of the instrument. ROC analyses between the rater total scores and dichotomized expert ratings (SDM yes/no) revealed a good discriminability of the OPTION total score. Physicians with more expertise in shared decision making received higher OPTION ratings. Conclusions The German version of the OPTION scale is reliable at total score level. Some items need further revision in the direction of more concrete, observable behaviour. We were only able to perform a quasi‐validation of the scale. Validity issues need further research efforts.

Reliability and validity of the Iranian version of the QAPACE in adolescents

Purpose

The aim of this study was to determine the reliability and validity of the Iranian version of the Quantification de l’Activite Physique en Altitude Chez les Enfants (QAPACE) in adolescents.

Methods

After linguistic validation, the Iranian version of the QAPACE was completed by 359 (52.4 % girls) schoolchildren, aged 15–18 years. Test–retest reliability of the questionnaire was determined by intraclass correlation coefficients (ICCs). For validation purposes, two methods were used for (1) the correlation between VO_2peak and the DEE and (2) known-group validity, which was examined by comparing the normal weight adolescents and those who were overweight/obese.

Results

ICCs for test–retest ranged from 0.79 to 0.98. The mean scores in test–retest surveys for total score and all of the subscores were significant (p < 0.05). Sex-specific analysis showed a significant correlation between VO_2peak and DEE over 12-month, school, and vacation periods in girls (p < 0.05). The mean values for all activities except for transportation, other activities in school, personal artistic activities, sport competition, and home activities were significantly lower in overweight/obese group than normal group.

Conclusion

Our results support the initial reliability and validity of the Iranian version of QAPACE as a daily physical activity measure in adolescents.

Preliminary reliability and validity of Persian version of the Family Dermatology Life Quality Index (FDLQI)

Purpose

Family Dermatology Life Quality Index (FDLQI) is an instrument for assessing the quality of life of family members of dermatologic patients. The aim of this study was to describe the cultural adaptation of this questionnaire and to assess psychometric properties of the Persian version.

Methods

At first, the questionnaire was translated into Persian, and then back-translation was performed. The whole cycle was repeated until a consensus was reached about the optimal translation. In the next step, cognitive debriefing was performed, and after approval of the Persian version by FDLQI developers, it was distributed among 100 family members of dermatological patients in order to evaluate its validity and reliability.

Results

Mean age of participants was 37.1 years (±12.3). Mean score of FDLQI was 15.4 (±5.5) with maximum and minimum scores of 30 and 6, respectively. The quality of life of studied participants showed no significant difference based on age-group, sex, educational level and the family relationship. Cronbach’s alpha was calculated as 0.87. Exploratory factor analysis revealed a one-factor solution that accounted for 40.7 % of the variance. The unidimensional model was supported by confirmatory factor analysis.

Conclusions

The results of the present study showed that the Persian version of FDLQI has acceptable factorial validity and internal consistency reliability.
