Social problem-solving deficits characterise individuals with traumatic brain injury (TBI), and poor social problem solving interferes with daily functioning and productive lifestyles. Therefore, it is of vital importance to use the appropriate instrument to identify deficits in social problem solving for individuals with TBI. This study investigates factor structure and item-level psychometrics of the Social Problem Solving Inventory-Revised: Short Form (SPSI-R:S), for adults with moderate and severe TBI. Secondary analysis of 90 adults with moderate and severe TBI who completed the SPSI-R:S was performed. An exploratory factor analysis (EFA), principal components analysis (PCA) and Rasch analysis examined the factor structure and item-level psychometrics of the SPSI-R:S. The EFA showed three dominant factors, with positively worded items represented as the most definite factor. The other two factors are negative problem-solving orientation and skills; and negative problem-solving emotion. Rasch analyses confirmed the three factors are each unidimensional constructs. It was concluded that the total score interpretability of the SPSI-R:S may be challenging due to the multidimensional structure of the total measure. Instead, we propose using three separate SPSI-R:S subscores to measure social problem solving for the TBI population.

社会问题解决缺陷是创伤性脑损伤 (TBI) 个体的特征,而社会问题解决不良会干扰日常功能和生产性生活方式。因此,使用适当的工具来确定患有TBI的人在解决社会问题方面的缺陷至关重要。本研究调查了中度和重度TBI成年人的社会问题解决清单修订: 简短形式 (spsi-r: S) 的因素结构和项目水平心理计量学。对完成spsi-r: S的90例中度和重度TBI成年人进行了二次分析。探索性因素分析 (EFA),主成分分析 (PCA) 和Rasch分析检查了spsi-r: S的因素结构和项目水平的心理计量学。全民教育显示了三个主要因素,措辞积极的项目是最明确的因素。另外两个因素是消极的问题解决方向和技能; 和消极的问题解决情绪。Rasch分析证实了这三个因素都是一维结构。结论是,由于总度量的多维结构,spsi-r: S的总分可解释性可能具有挑战性。相反,我们建议使用三个单独的spsi-r: S子分数来衡量TBI人群的社会问题解决方案。
