In patient-centered practice, instruments need to assess outcomes that are meaningful to patients with hand conditions. It is unclear which assessment tools address these subjective perspectives best.
The aim of this study was to establish the construct validity of the Canadian Occupational Performance Measure (COPM) in relation to the Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire and the Michigan Hand Outcomes Questionnaire (MHQ) in people with hand conditions. It was hypothesized that COPM scores would correlate with DASH and MHQ total scores only to a moderate degree and that the COPM, DASH questionnaire, and MHQ would all correlate weakly with measures of hand impairments.
This was a validation study.
The COPM, DASH questionnaire, and MHQ were scored, and then hand impairments were measured (pain [numerical rating scale], active range of motion [goniometer], grip strength [dynamometer], and pinch grip strength [pinch meter]). People who had received postsurgery rehabilitation for flexor tendon injuries, extensor tendon injuries, or Dupuytren disease were eligible.
Seventy-two participants were included. For all diagnosis groups, the Pearson coefficient of correlation between the DASH questionnaire and the MHQ was higher than .60, whereas the correlation between the performance scale of the COPM and either the DASH questionnaire or the MHQ was lower than .51. Correlations of these assessment tools with measures of hand impairments were lower than .46.
The small sample sizes may limit the generalization of the results.
The results supported the hypotheses and, thus, the construct validity of the COPM after surgery in people with hand conditions.
在以患者为中心的医疗实践中，评估工具需要衡量对手部疾病患者有意义的治疗效果。目前尚不清楚哪种评估工具能最好地反映这些主观观点。
本研究旨在确定加拿大职业表现测量表（COPM）与上肢、肩部和手部功能障碍问卷（DASH）以及密歇根手部结果问卷（MHQ）在手部疾病患者中的结构效度。研究假设COPM得分与DASH和MHQ总分仅呈中度相关，且COPM、DASH问卷和MHQ与手部损伤测量指标的相关性均较弱。
这是一项效度验证研究。
对COPM、DASH问卷和MHQ进行评分，然后测量手部损伤情况（疼痛[数字评分量表]、主动活动范围[角度计]、握力[测力计]和捏力[捏力计]）。接受屈肌腱损伤、伸肌腱损伤或掌腱膜挛缩症术后康复治疗的患者符合入选标准。
共纳入72名参与者。在所有诊断组中，DASH问卷与MHQ之间的Pearson相关系数高于0.60，而COPM表现量表与DASH问卷或MHQ之间的相关性低于0.51。这些评估工具与手部损伤测量指标的相关性低于0.46。
样本量较小可能会限制研究结果的推广。
研究结果支持了假设，因此也支持了COPM在手部疾病患者术后的结构效度。
