Older adults have elevated suicide rates, and identification of protective factors, such as reasons for living, is important in preventing suicide. The Reasons for Living-Older Adults scale (RFL-OA) is a 69-item measure of these protective factors in late life, which yields good psychometric properties. However, its length limits its utility in some clinical and research contexts where a shorter measure is ideal. The objective of this study was to create a shortened version of the RFL-OA.
First, data collected previously during validation of the original RFL-OA (n = 199, age 65 and older, 65% female) were used to select 30 items, spanning all content areas, that were highly endorsed. Second, new data were collected (n = 219, age 60 and older, 52% female) with the 30-item RFL-OA and measures of depression, hopelessness, suicidal ideation, religiosity, health, and social desirability to examine the measure's internal consistency and convergent and discriminant validity.
Scores on the 30-item RFL-OA exhibited strong internal consistency. The short RFL-OA demonstrated good convergent validity via significant, moderate correlations with suicidal ideation, hopelessness, depression, and religiosity. It demonstrated adequate discriminant validity via only small correlations with disability, subjective health, and social desirability.
The shorter RFL-OA has good psychometric properties among community-dwelling older adults. It may have greater utility, compared to the original 69-item measure, for clinicians and researchers with limited time but who want to assess protective factors against suicidal behavior in late life.
老年人的自杀率较高,识别保护因素(如生存理由)对于预防自杀至关重要。《老年人生活理由量表》(RFL-OA)是一种用于评估晚年生活中这些保护因素的 69 项测量工具,具有良好的心理测量学特性。然而,由于其长度限制,在某些临床和研究情境中使用起来不太方便,此时更理想的是使用较短的测量工具。本研究的目的是创建 RFL-OA 的简化版本。
首先,我们使用先前在 RFL-OA 原始版本验证过程中收集的数据(n=199,年龄在 65 岁及以上,65%为女性),选择了 30 项高度被认可的涵盖所有内容领域的项目。其次,我们使用新收集的数据(n=219,年龄在 60 岁及以上,52%为女性)和 30 项 RFL-OA 以及抑郁、绝望、自杀意念、宗教信仰、健康和社会期望测量工具,来检验该测量工具的内部一致性、聚合效度和区分效度。
30 项 RFL-OA 的得分表现出较强的内部一致性。短版 RFL-OA 与自杀意念、绝望、抑郁和宗教信仰呈显著的中度相关,表明其具有良好的聚合效度。它与残疾、主观健康和社会期望的相关性较小,表明其具有足够的区分效度。
在社区居住的老年人中,简化后的 RFL-OA 具有良好的心理测量学特性。与原始的 69 项测量工具相比,它可能更适用于时间有限但希望评估晚年自杀行为保护因素的临床医生和研究人员。
