目的：建立一个有效的、以照顾者为基础的测量量表，对86例穿透性脑损伤(TBI)患者和65例因额颞叶痴呆和皮质基综合征所致的神经退行性变患者进行多领域的性变化评估。采用非参数Mokken项目反应理论(IRT)方法对问卷的维度、单调性、项目辨别力和可测性进行评价。这些域具有足够的可靠性(ROO.70到.80)，同时满足中等可伸缩性的Mokken IRT标准。这三个域名分别被标记为“亲社会性行为”(H=9.42)、“性兴趣”(H=9.50)和“不适当的性行为”(H=9.41)。第四个维度是“脱离”(H=0.47)，但条目很少。结论：建立了与性行为的三个独特方面有关的条目组的结构效度。这些发现支持进一步使用SNIQ来评估和研究痴呆症和脑损伤患者的性行为。
Objective: To develop a validated, caregiver-based measurement scale to assess sexual changes across several domains in a sample of 86 patients with penetrating traumatic brain injury (TBI) and 65 patients with neurodegeneration due to frontotemporal dementia and corticobasal syndrome.Methods: A new measure, the Sexual Symptoms in Neurological Illness and Injury Questionnaire (SNIQ), was constructed. Dimensionality, monotonicity, item discrimination power, and scalability were evaluated using nonparametric Mokken item response theory (IRT) methodology.Results: Three primary domains were established. The domains presented with sufficient reliability (rho .70 to .80), while meeting the Mokken IRT criteria of medium scalability. The domains were labeled ‘Prosocial sexual behaviour’ (H = .42), ‘Sexual interest’ (H = .50), and ‘Inappropriate sexual behaviour’ (H = .41). A fourth dimension emerged, ‘Detachment’ (H = .47), but with very few items.Conclusions: Construct validity was established for groups of items pertaining to three unique aspects of sexuality. These findings support further use of the SNIQ in assessing and researching sexual behaviours in patients with dementia and brain injury.
