Abstract

Background: Persevering hope, defined as the ability to maintain motivation when goals seem unattainable, represents a crucial psychological resource for mental health. This study aimed to examine the psychometric properties of the Turkish version of the Persevering Hope Scale (PHS) primarily using Rasch analysis, supplemented by classical test theory indices including internal consistency reliability.

Method: The study included 634 university students (72.9% female; Mage = 22.51 ± 4.08). Rasch analysis was employed to assess unidimensionality, item fit, and differential item functioning (DIF). Criterion-related validity was evaluated through correlations with the Adult Hope Scale, and convergent validity was examined using measures of theoretically related constructs and psychological health outcomes.

Results: Rasch analysis indicated that all items demonstrated good fit (infit/outfit MNSQ = 0.71-1.17), with no evidence of differential item functioning (DIF) across gender. Furthermore, the results supported the unidimensional structure of the PHS (explained variance = 67.1%). The scale showed strong criterion-related validity (rs = 0.41-0.56, p < 0.001). Convergent validity was supported by significant correlations with flourishing (r = 0.45, p < 0.001) and psychological health outcomes.

Conclusions: The Turkish version of the PHS demonstrates robust psychometric properties with strong evidence of reliability, construct validity, and measurement invariance across genders. These findings support its use as a culturally valid instrument for assessing persevering hope in Turkish populations.

土耳其版坚持希望量表的心理测量特征：一项Rasch分析研究。

背景：坚持希望，定义为在目标似乎无法实现时保持动力的能力，是心理健康的重要心理资源。本研究主要采用Rasch分析，并辅以内部一致性信度等经典测试理论指标，对土耳其版“坚持希望量表”（PHS）的心理测量特性进行检验。方法：研究对象为634名大学生，其中女性72.9%，男性= 22.51±4.08。采用Rasch分析评估单维性、项目契合度和差异项目功能（DIF）。通过与成人希望量表的相关性来评估标准相关效度，并通过理论相关构念和心理健康结果的测量来检验收敛效度。结果：Rasch分析表明，所有项目都表现出良好的契合度（infit/outfit MNSQ = 0.71-1.17），没有证据表明性别之间存在差异项目功能（DIF）。此外，结果支持小灵通的单维结构（解释方差= 67.1%）。结论：土耳其版PHS量表在信度、结构效度和测量不变性方面具有很强的心理测量特性。这些发现支持将其作为一种文化上有效的工具来评估土耳其人口的持久希望。
