Abstract

Objectives: To investigate the reliability and the construct validity of the Participation Scale (P-scale) in adults with Spinal Cord Injury (SCI).

Design: A cross-sectional study.

Setting: : SARAH Network of Rehabilitation Hospitals, Brazil.

Participants: : One hundred individuals with SCI.

Interventions: : Not applicable.

Outcome measures: : Sociodemographic and clinical characteristics were investigated. To assess reliability the P-scale was applied twice with a one-week interval. To assess construct validity the Functional Independence Measure, the Beck Depression Inventory, and the Accessibility Perception Questionnaire were administered.

Results: The mean age of the participants was 38.9 ± 12.80 years. The majority were male (70%) and had traumatic injuries (74%). The P-scale showed significant correlations with the Functional Independence Measure motor domain (r_s = -0.280) and cognitive domain (r_s = -0.520); with the Beck Depression Inventory score (r_s= 0.610); with the Accessibility Perception Questionnaire displacement domain (r_s= -0.620) and psycho-affective domain (r_s= 0.530). Mean scores obtained on the P-scale differed significantly between the groups with and without depressive symptoms (P = 0.001), neuropathic pain (P = 0.033), and functional dependence (P = 0.001). There was no difference between the paraplegic and quadriplegic groups. The P-scale had adequate internal consistency (Cronbach's alpha = 0.873), excellent test-retest reliability (ICC_2,1= 0.992; 95% CI = 0.987-0.994), and in the Bland-Altman plot analysis, only six values fell outside the limits of agreement.

Conclusion: Our results support the use of the P-scale to assess the participation of individuals with SCI in research and clinical practice.

脊髓损伤患者参与量表（P-scale）的结构有效性和可靠性。

目的：研究脊髓损伤成人参与量表（P-scale）的信度和结构效度：调查脊髓损伤（SCI）成人参与量表（P-scale）的信度和结构效度：横断面研究：参与者： 100 名脊髓损伤患者：100 名 SCI 患者：结果测量调查社会人口学和临床特征。为评估可靠性，两次使用P量表，每次间隔一周。为了评估构建有效性，采用了功能独立性测量法、贝克抑郁量表和无障碍感知问卷：参与者的平均年龄为 38.9 ± 12.80 岁。大多数参与者为男性（70%），有外伤（74%）。P量表与功能独立性测量运动领域（rs = -0.280）和认知领域（rs = -0.520）、贝克抑郁量表得分（rs = 0.610）、无障碍感知问卷位移领域（rs = -0.620）和心理情感领域（rs = 0.530）呈显著相关。有抑郁症状组与无抑郁症状组（P = 0.001）、神经病理性疼痛组（P = 0.033）和功能依赖组（P = 0.001）的 P 量表平均得分差异显著。截瘫组和四肢瘫痪组之间没有差异。P 量表具有充分的内部一致性（Cronbach's alpha = 0.873）和极好的测试-再测可靠性（ICC2,1 = 0.992; 95% CI = 0.987-0.994），在布兰-阿尔特曼图分析中，只有六个值超出了一致的范围：我们的研究结果支持使用 P 量表来评估 SCI 患者参与研究和临床实践的情况。
