尽管呼吁考虑未来时间洞察力（FTP）作为一个多维度的结构，主要是一维测量工具已被使用。本研究有两个目的：（a）编制一份用于评估成年人FTP的简明多维度问卷，并评估其心理测量学特性;（B）研究FTP各维度的年龄关联和年龄组差异。心理测量评估包括探索性因素分析（EFA）和验证性因素分析（CFA）、信度和效度分析以及测量不变性测试。采用零阶相关和偏相关检验FTP各维度与年龄的相关性，采用多变量方差分析检验年龄组差异，EFA和CFA支持三因素解决方案：未来是开放的，未来是有限的，未来是模糊的。这一因素结构的度量测量不变性在三个年龄组中得到证实。信度和效度分析提供了证据的声音的简短问卷的心理测量特性。年龄与未来开放负相关，与未来有限正相关。年轻人表现出显着更大的模糊性，对未来比中年或老年aduls.This研究提供了证据，支持一个新的简短的多维FTP量表的心理测量学特性。它还提供了证据的年龄协会和年龄组的差异与寿命发展理论相一致的模式。
Despite calls for the consideration of future time perspective (FTP) as a multidimensional construct, mostly unidimensional measurement instruments have been used. This study had two objectives: (a) to develop a brief multidimensional questionnaire for assessing FTP in adulthood and evaluate its psychometric properties; and (b) to examine age associations and age-group differences of the dimensions of FTP.Data were collected from 625 community-residing adults between the ages of 18 and 93, representing young, middle-aged, and older adults. The psychometric evaluation involved exploratory factor analyses (EFA) and confirmatory FA (CFA), reliability and validity analyses, and measurement invariance testing. Zero-order and partial correlations were used to examine the association of the dimensions of FTP with age, and multivariate analysis of variance was used to examine age-group differences.EFA and CFA supported a three-factor solution: Future as Open, Future as Limited, and Future as Ambiguous. Metric measurement invariance for this factor structure was confirmed across the three age groups. Reliability and validity analyses provided evidence of sound psychometric properties of the brief questionnaire. Age was negatively associated with Future as Open and positively associated with Future as Limited. Young adults exhibited significantly greater ambiguity toward the future than middle-aged or older adults.This study provides evidence in support of the psychometric properties of a new brief multidimensional FTP scale. It also provides evidence for a pattern of age associations and age-group differences consistent with life-span developmental theory.
