ABSTRACT

Falls are a significant medical and economical concern worldwide. Younger individuals with visual impairment (VI) may be more susceptible to falling and fall-related injuries when compared to peers without a VI. Self-perceived balance confidence is a psychological construct that may predict and/or mediate fall- or other health-related outcomes in youth with VI. However, extensive psychometric vetting of falls-related self-efficacy self-report inventories (such as the Activity-specific Balance Confidence Scale [ABC]) have not occurred in youth with VI. In line with classical test theory, the purposes of this study were to examine the immediate measurement properties of ABC scores in youth with VI and to derive and analyze a short version of the ABC in youth with VI (N=101). Total and item-level ABC (and the newly developed ABC-6VI) scores presented with strong-to-acceptable forms/levels of reliability and validity. ABC-6VI scores appear to have certain psychometric limitations (i.e., increased variability; decreased stability).

摘要

跌倒是世界范围内重要的医疗和经济问题。与没有视力障碍的同龄人相比，视力障碍 (VI) 的年轻人可能更容易受到跌倒和跌倒相关伤害。自我感知的平衡信心是一种心理结构，可以预测和/或调节 VI 青少年的跌倒或其他与健康相关的结果。然而，对跌倒相关的自我效能感自我报告清单（如活动特定平衡信心量表 [ABC]）进行广泛的心理测量审查尚未在 VI 青少年中进行。根据经典测试理论，本研究的目的是检验青少年 VI 的 ABC 分数的直接测量特性，并推导和分析青少年 VI ( N=101)。总分和项目级别的 ABC（以及新开发的 ABC-6VI）分数以强到可接受的形式/可靠性和有效性水平呈现。ABC-6VI 评分似乎有一定的心理测量限制（即变异性增加；稳定性降低）。
