Brief summary

Background: Prolonged sitting behavior, characterized by minimal energy expenditure, poses significant health risks, especially for chronic kidney disease (CKD) patients undergoing hemodialysis. This sedentary behavior can lead to various health complications and a reduced quality of life (QOL). Objectives: This study aims to evaluate the validity and reliability of the Turkish adaptation of the Ottawa Sitting Scale (OSS) in assessing sitting behavior among CKD patients. Methods: A total of 130 CKD patients undergoing hemodialysis participated in this cross-sectional study conducted in XXX province between January 2023 and September 2023. The OSS, along with the Physical Activity Scale (FAS), Sitting Behavior Assessment (SBA), and Quality of Life Scale (QOL), was administered. Data analysis involved assessing the internal consistency, factor structure, and concurrent validity of the OSS.

Interventions

OTHERhemodialysis group

Data were collected from patients undergoing treatment at a hemodialysis center in Kırşehir. Participants were informed about the study objectives and provided written consent. Data collection took approximately 20-30 minutes per participant and included a face-to-face interview where socio-demographic and clinical information was recorded.

Intervention model description

The sample size was determined based on the recommendations for validation studies, which suggest a minimum of 5 to 10 participants per item on the scale being validated. Given that the OSS comprises 12 items, a minimum of 60 participants was deemed necessary. However, to account for potential dropouts and to enhance the robustness of the findings, 130 participants were recruited.

Primary

MeasureTime frameDescription
Ottawa Sitting Scale (OSS):24 weeksThe OSS is a 6-item scale designed to assess sitting balance. Each item is performed with feet supported and unsupported, resulting in a total of 12 items. A 4-point Likert-type response scale was used for each item. The total score ranges from 0 to 48, with higher scores indicating better sitting behavior. The cross-cultural adaptation of the OSS followed the guidelines by Beaton et al. (2000), involving forward and backward translations, synthesis, expert committee review, and pre-testing on 30 elderly adults.
