To examine the psychometric qualities and develop the clinical utility of the Sydney Psychosocial Reintegration Scale (SPRS) as a measure of participation in people with traumatic brain injury.
Data generated from previous prospective studies.
SUBJECTS/PATIENTS: Convenience samples of healthy community-based volunteers (n=105) and people with severe brain injury (n=510).
(i) The equivalence of a new 5-point version of the SPRS was determined vs the original 7-point version; (ii) construct validity was tested using Rasch analyses; (iii) normative and comparative data tables were produced, and data examined for floor/ceiling effects; (iv) a reliable change index score was generated.
Patterns of psychometric properties for the 5- and 7-point versions were almost identical (e.g. total scores rs=0.98). Rasch analyses on Forms A and B found good fit to the model, for person (3.36 and 3.03, respectively) and item (7.78 and 7.25, respectively) separation; reliability coefficients were high (all ≥ 0.90). Mean infit statistics met standard criteria (between 0.7 and 1.3). No floor/ceiling effects were detected. The reliable change index value was calculated for the total score for Form A using logit scores, and a conversion table provided.
The 5-point version of the SPRS demonstrates strong psychometric qualities as a measure of participation after traumatic brain injury.
检验悉尼心理社会康复量表(SPRS)作为衡量创伤性脑损伤患者参与度的指标的心理测量学质量和临床实用性。
来自先前前瞻性研究的数据。
受试者/患者:方便抽取的健康社区志愿者样本(n=105)和严重脑损伤患者样本(n=510)。
(i)确定新的 5 分制 SPRS 版本与原始 7 分制版本的等效性;(ii)使用 Rasch 分析测试结构有效性;(iii)生成规范和比较数据表,并检查有无地板/天花板效应;(iv)生成可靠变化指数评分。
5 分制和 7 分制版本的心理测量特性模式几乎相同(例如总分 rs=0.98)。A 型和 B 型表单的 Rasch 分析发现,人与项目的拟合度良好(分别为 3.36 和 3.03,7.78 和 7.25);可靠性系数均较高(均≥0.90)。平均内特统计符合标准(0.7 至 1.3 之间)。未发现地板/天花板效应。使用对数得分计算 A 型表单总分的可靠变化指数值,并提供转换表。
5 分制 SPRS 版本作为衡量创伤性脑损伤后参与度的指标,具有较强的心理测量学质量。
