Because the interpersonal skills of individuals with dementia often decline, family members may question their own ability to interact meaningfully. These family members may experience fear of incompetence (i.e., fear of being unable to relate in a meaningful way or take care of a close family member with dementia). Thus, the goal of this research was to develop, refine, and psychometrically validate a scale (Fear of Incompetence-Dementia Scale; FOI-D) assessing fear of incompetence in the context of relationships with a close family member diagnosed with dementia. Three online studies were conducted to accomplish the primary objective. In Study One, the factor structure of the FOI-D was assessed by conducting an exploratory factor analysis using data from 710 adults who indicated having a close living family member who had been diagnosed with dementia. In Study Two, the factor structure was validated via a confirmatory factor analysis and the psychometric properties were established using data from 636 adults who had a family member with dementia. Finally, Study Three determined the temporal consistency of the scale by retesting 58 participants from Study Two. The results from Study One indicated that the FOI-D Scale accounted for 51.75% of the variance and was comprised of three subscales: the Interaction Concerns subscale, the Caregiving Concerns subscale, and the Knowledge Concerns subscale. In Study Two, the three-factor structure was supported, resulting in a 58-item scale. Investigation of the psychometric properties demonstrated the FOI-D to be reliable and valid. In Study Three, the FOI-D Scale demonstrated excellent temporal consistency. This research provides future investigators, educators, and practitioners with an adaptable comprehensive tool assessing fear of incompetence in a variety of settings.
由于痴呆症患者的人际交往能力往往会下降，家庭成员可能会质疑自己进行有意义互动的能力。这些家庭成员可能会经历对无能力的恐惧（即害怕无法以有意义的方式相处或照顾患有痴呆症的亲密家庭成员）。因此，本研究的目的是开发、完善并对一个量表（痴呆症无能力恐惧量表；FOI-D）进行心理测量学验证，该量表用于评估在与被诊断患有痴呆症的亲密家庭成员的关系中对无能力的恐惧。为实现这一主要目标，进行了三项在线研究。在研究一中，通过对710名成年人的数据进行探索性因素分析，评估了FOI-D的因素结构，这些成年人表示有一位被诊断患有痴呆症的亲密家庭成员与他们共同生活。在研究二中，通过验证性因素分析对因素结构进行了验证，并使用636名有痴呆症家庭成员的成年人的数据确定了心理测量学特性。最后，研究三通过对研究二中的58名参与者进行重新测试，确定了该量表的时间一致性。研究一的结果表明，FOI-D量表解释了51.75%的方差，由三个子量表组成：互动担忧子量表、照护担忧子量表和知识担忧子量表。在研究二中，三因素结构得到支持，形成了一个58个条目的量表。对心理测量学特性的调查表明，FOI-D是可靠且有效的。在研究三中，FOI-D量表表现出了出色的时间一致性。本研究为未来的研究者、教育工作者和从业者提供了一个可在各种环境中评估无能力恐惧的适应性强的综合工具。
