Reliability of cross-cultural adapted Turkish version of the Pediatric Outcomes Data Collection Instrument (PODCI).

BACKGROUND

The Pediatric Outcomes Data Collection Instrument (PODCI) has been created to evaluate functional status, to assess therapeutic needs and changes after treatment in 2 to 18 years old children and adolescents who have orthopedic problems. The PODCI has three forms; parent form for children, parent and self report forms for adolescents. Instrument has 86 items assessing upper extremity and physical function', transfer and basic mobility', sports and physical function', pain/comfort', happiness', global functioning' and `expectations from treatment domains'. The PODCI has been validated in multiple languages. The aim of this study was to investigate the reliability of the cross-cultural adapted Turkish version of the PODCI parent forms for children and adolescents in a variety of chronic musculoskeletal disorders.

METHOD

This was a methodological study. The instrument was translated and cross-culturally adapted into Turkish. Turkish version was called Bedensel İşlevsellik Değerlendirme Aracı (BIDA). It was completed by the parents/caregivers of ninety-eight children and adolescents being treated at Marmara University Medical School Department of Physical Medicine and Rehabilitation outpatient clinics at the baseline and 2-4 weeks after between April 2013-October 2013. Internal consistency and test-retest reliability (ICC) were determined.

RESULTS

Internal consistency of the subscales and test/retest cronbach alpha values were 0.90-0.91 (r= 0.71, p= 0.000) for upper extremity and physical function''; 0.95-0.95 (r= 0.84, p= 0.000) for transfer and basic mobility''; 0.93-0.91 (r= 0.78, p= 0.000) for sports and physical functioning''; 0.77-0.82 (r= 0.45, p= 0.000) for happiness'' and 0.96-0.96 (r= 0.82, p= 0.000) for ``global functioning''. Pain/comfort subscale showed low internal consistency (-0.38-0.49; r= 0.34, p= 0.004).

CONCLUSION

The Turkish version of the PODCI was found to be a reliable instrument to evaluate functionality of children and adolescents with chronic musculoskeletal disorders.
