BACKGROUND/OBJECTIVES: This study aimed to address limitations of the pilot reliability study on the Sensory-Motor Dysfunction Questionnaire (SMD-Q) in two parts. Part 1 evaluated the intra-rater reliability of SMD-Q version 2 (V2). Part 2 addressed V2's limitations before assessing the intra-rater reliability of version 3 (V3). V2 framed questions as "over the past week", whereas V3 also framed questions as "in a typical/usual week".
The SMD-Q was administered via Qualtrics at baseline and 4 to 7 days later to subclinical neck pain participants, 51 in part 1 (32 F; mean age ± SD: 21.17 ± 2.66 y) and 27 in part 2 (20 F; mean age ± SD: 21.89 ± 2.81 y). Reliability statistics (quadratic weighted kappa (K) and Cronbach's alpha (α)) were calculated for all items (V2) and total scores (V2 and V3).
There was excellent agreement for V2 total scores (K ≥ 0.75), and V3 total scores for "in a typical/usual week" (K ≥ 0.75), but fair to good agreement for V3 total scores of "over the past week" (0.40 < K < 0.75). V2 had acceptable (0.7 ≤ α < 0.8) to good internal consistency (0.8 ≤ α < 0.9), while V3 had good internal consistency for both administrations.
Versions 2 and 3 of the SMD-Q appear to reliably capture disordered sensorimotor integration in people with subclinical neck pain, with improved reliability in V3 when questions are framed as "in a typical/usual week". However, further research is needed to confirm this finding.
背景/目的：本研究旨在分两部分解决感觉运动功能障碍问卷（SMD-Q）初步信效度研究的局限性。第一部分评估了SMD-Q第2版（V2）的评分者内信效度。第二部分在评估第3版（V3）的评分者内信效度之前，解决了V2的局限性。V2将问题设定为“在过去一周内”，而V3也将问题设定为“在一个典型/平常的一周内”。
通过Qualtrics平台在基线时以及4至7天后对亚临床颈部疼痛参与者进行SMD-Q问卷调查，第一部分有51人（32名女性；平均年龄±标准差：21.17±2.66岁），第二部分有27人（20名女性；平均年龄±标准差：21.89±2.81岁）。计算所有项目（V2）和总分（V2和V3）的信度统计量（二次加权kappa（K）和克朗巴哈系数（α））。
V2总分（K≥0.75）以及V3中“在一个典型/平常的一周内”的总分具有高度一致性（K≥0.75），但V3中“在过去一周内”的总分一致性为中等至高度（0.40＜K＜0.75）。V2具有可接受的（0.7≤α＜0.8）至良好的内部一致性（0.8≤α＜0.9），而V3在两次施测中均具有良好的内部一致性。
SMD-Q的第2版和第3版似乎能够可靠地反映亚临床颈部疼痛患者感觉运动整合功能紊乱，当问题设定为“在一个典型/平常的一周内”时，V3的信效度有所提高。然而，需要进一步的研究来证实这一发现。
