Cultural adaptation and validation in Italian of the Seated Postural Control Measure for Adults 2.0

The aim of this study was to assess the cultural adaptation and validation in Italian of the Seated Postural Control Measure for Adults 2.0 (SPCMA 2.0).

The original scale was translated and culturally adapted from French to Italian using the "Translation and Cultural Adaptation of Patient Reported Outcomes Measures-Principles of Good Practice" guidelines. Its internal consistency and test-retest reliability were examined. Its concurrent validity was evaluated using Pearson correlation coefficients with the Italian version of the Wheelchair use Confidence Scale and Wheelchair Skills Test 4.2.

Fifty-nine people were evaluated and re-evaluated after 48 h. Most of the items and subscale totals were stable in the 2 evaluations as they reported an intraclass correlation coefficient value of >0.77. The test-retest analysis of the dynamic evaluation was performed on the same patients 48 h apart. The analysis for construct validity showed statistically significant correlations with Wheelchair use Confidence Scale and Wheelchair Skills Test 4.2.

Seated Postural Control Measure for Adults 2.0 is one of the few tools that allow researchers to perform a quantitative and standardized posture assessment in a cost-effective and time-saving way. Furthermore, it has been demonstrated that it is an easy-to-administer scale and requires readily available tools. The limitations of this study highlighted above and the need to use quantitative and qualitative tools in clinical practice imply the need to conduct future studies.
