Adaptation to Spanish and Validity by Wearable Sensors of the Physical Activity Recall Assessment for People with Spinal Cord Injury

Abstract

No Spanish-language tool exists to assess physical activity in people with spinal cord injuries. This work aimed to provide a valid Spanish version of the Physical Activity Recall Assessment for People with Spinal Cord Injury (PARA-SCI). It was conducted in three phases. First, translation and cross-cultural adaptation. Second, a reliability assessment through inter-rater reliability (n = 25) and test–retest reliability (n = 50). Third, validity assessment, comparing PARA-SCI-Spanish and wearable sensors (n = 13), as well as analyzing PARA-SCI-Spanish results between known groups (n = 235). Intraclass correlation coefficients ranged from 0.36 to 0.95. The correlations between the wearable sensors and the PARA-SCI-Spanish were r = 0.67, p =.005 (moderate to vigorous physical activity) and r = 0.62, p =.01 (total activity). The known-groups analyses demonstrated differences in accord with previous research and not differing according to the interview mode. The PARA-SCI-Spanish was a reliable and valid tool in telephone and face-to-face interviews.
