Inter-Rater and Test-Retest Reliability of the German Pediatric Evaluation of Disability Inventory (PEDI-G)

Validity and test-retest reliability of the Ugandan version of the Pediatric Evaluation of Disability Inventory (PEDI-UG) in children and youth with cerebral palsy

BACKGROUND

Validity of the Ugandan version of the Pediatric Evaluation of Disability Inventory (PEDI-UG) was previously investigated on typically developing children. This study aimed to investigate the validity, test-retest reliability and minimal detectable change (MDC) of the PEDI-UG in children and youth (C&Y) with cerebral palsy (CP).

METHOD

A cross-sectional study design with 118 C&Y with CP (44.7% girls) aged 10 months-22.5 years were included in the study; 37 of them completed the PEDI-UG twice to investigate test-retest reliability, determined by calculating the intraclass correlation coefficient (ICC). Additionally, data from 249 typically developing children were used for differential item functioning (DIF) analysis. The validity of the PEDI-UG was investigated by Rasch analysis. The Kruskal-Wallis test and Spearman's correlation coefficient were calculated to investigate associations between PEDI-UG scores and external classification systems.

RESULTS

The principal component analysis of residuals indicated unidimensionality in all domains. The ICC values were excellent (0.98-0.99), and the MDCs were less than 6 and 13 (on a 0-100 scale) for the functional skills and caregiver assistance parts, respectively. The four-category caregiver assistance rating scale fulfilled the criteria for the analysis of rating scale functioning. In total, 78 of 189 items in the functional skills domain and two items in the caregiver assistance domain demonstrated DIF between C&Y with CP and TD children. The Kruskal-Wallis test (p < 0.05) and Spearman's correlation (coefficients of -0.93 to -0.78) supported the validity of PEDI-UG.

CONCLUSION

The current diagnose-specific version of PEDI-UG demonstrates evidence for validity as a measure of ability in C&Y with CP in Uganda and other similar settings, being a promising tool for use in clinical practice and research. Conversion tables and MDC values are provided to facilitate clinical adoption of the measure.

Evaluation of test-retest reliability and concurrent validity of the Italian version of the pediatric evaluation of disability inventory in children with down syndrome: A cross-sectional study

PURPOSE

Down Syndrome (DS) is a common genetic disorder caused by trisomy 21. Due to cognitive challenges associated with DS, individuals often experience difficulty performing activities of daily living (ADLs), at levels that can range from mild to significant. This study aimed to measure psychometric properties of the Italian version of the Pediatric Evaluation of Disability Inventory (PEDI-I) in the DS population.

METHODS

The PEDI-I was administered to children with DS. The internal consistency was examined using Cronbach's Alpha. Test-retest reliability was demonstrated by intraclass correlation coefficient (ICC) and Bland-Altman plots. The concurrent validity was evaluated with the Italian version of the Barthel Index.

RESULTS

The PEDI-I was administered to 54 children with DS. Cronbach's Alpha showed statistically significant values (0.899 -0.986). The ICC confirmed the reproducibility of the scale with a range of (0.988 -1), while Bland-Altman plots showed a smallest detectable change of (0.18-1.63). The Pearson Correlation Coefficient with the Barthel Index showed statistically significant values for all PEDI-I subscales (range 0.75-0.95).

CONCLUSION

The study provides evidence of good test-retest reliability and convergent validity when used in children with DS. Other psychometric proprieties need to be investigated in future studies.

Are the American normative standard scores applicable to the German version of the Pediatric Evaluation of Disability Inventory (PEDI-G)?

BACKGROUND

The Pediatric Evaluation of Disability Inventory (PEDI) is an assessment to evaluate children's performance in activities of daily living.

AIMS

The study investigated if the normative standard scores of the PEDI are applicable to the German version of the PEDI (PEDI-G) in Germany, Austria and Switzerland, and whether there are differences in the applicability of the PEDI-G between the three countries.

MATERIALS AND METHODS

75 children with normal development (35 girls, 40 boys) from Germany (n = 17), Austria (n = 16), and Switzerland (n = 42) aged between 0.9 month and 7.3 years (SD = 2.03) participated in the study. Descriptive statistics, independent samples t-tests, univariate analyses of variance (ANOVA) and post hoc Tukey tests were applied.

RESULTS

No significant differences were identified. However, the German-speaking sample showed higher scores for the domain social function in both scales and in the Caregiver Assistance Scale self-care. Lower scores were identified in the Functional Skills Scale mobility.

CONCLUSIONS AND SIGNIFICANCE

The results support that the normative standard scores of the PEDI are applicable to the PEDI-G and for Austria, Germany and Switzerland, as no significant differences between the countries were identified. However, the generalizability of the results is limited due to sample size and recruitment procedures.

Administration of the German Pediatric Evaluation of Disability Inventory (PEDI-G) Using the Mode of Observation in Children Undergoing Inpatient Rehabilitation: A Reliability and Validity Study

Aims: To investigate inter-rater reliability, concurrent validity, and feasibility of the German Pediatric Evaluation of Disability Inventory (PEDI-G) using the mode of observation in a Swiss inpatient rehabilitation setting with the Functional Independence Measure for Children (WeeFIM®) as criterion.Methods: Cross-sectional clinimetric study including 36 children and adolescents with median age 10.8 (quartiles 8.7, 13.0) years with neurological/neuro-orthopedic disorders. Data were collected by healthcare professionals through observation. Analyses were performed using intraclass correlation coefficients (ICC_2,1), standard error of measurement (SEM_Agreement), Bland-Altman plots, Cohen's Kappa κ, percentage agreement, and correlations.Results: Excellent inter-rater reliability (ICCs_2,1 ≥ 0.97), small SEMs and acceptable limits of agreement for the Functional Skills Scale (FSS) and Caregiver Assistance Scale (CAS) were found. No systematic differences between raters existed. Cohen's Kappa for inter-rater agreement of the Modifications Scale (MS) ranged from poor to strong (-0.06 ≤ κ ≤0.85). Excellent concurrent validity for FSS and CAS with the WeeFIM^® (ρ  ≥ 0.96), and excellent correlations of FSS and CAS with each other (ρ  ≥ 0.98) were identified.Conclusion: The German PEDI-G seems to be a reliable and valid, but time-consuming tool when applied in an inpatient setting using observation.

Psychometric properties of the German Version of the Pediatric Evaluation of Disability Inventory (PEDI-G): A factor analysis

BACKGROUND

Activities of daily living (ADL) are crucial for children because they enable them to participate in everyday life. For the evaluation of children`s ADL performance, health professionals such as occupational therapists use standardized ADL assessments. To implement assessments into practice it is important that the score generated from an assessment can be viewed as a unidimensional measure.

AIM

To investigate the factor structure of the German Pediatric Evaluation of Disability Inventory (PEDI-G) in a sample of typically developing children and children with an impairment.

MATERIAL AND METHODS

An exploratory factor analysis (EFA) with factor rotation was performed to assess the factor structure for the PEDI-G domains (self-care, mobility and social function) of the Functional Skills Scale and the Caregiver Assistance Scale.

RESULTS

262 children (118 (45%) girls and 144 (55%) boys) participated in this study. Their mean age (SD) was 4 years (SD 1.91). Results suggest that the PEDI domains of the Functional Skills Scale and the Caregivers Assistance Scale can be used as unidimensional measures to evaluate child`s ability to perform activities of daily living.

CONCLUSION

The results of this study support the use of the PEDI-G for research and practice in Austria, Germany and Switzerland.
