psychometric qualities

心理测量素质
  • 文章类型: Journal Article
    快速适应环境的突然变化是灵活的人类行为的标志。许多计算,神经影像学,甚至研究这种认知过程的临床研究也依赖于一种称为预测推理任务的行为范式。然而,这项任务的心理测量质量从未被检查过,没有答案,它是否确实适合在受试者内部和受试者之间捕获行为变化。采用大规模重测设计(T1:N=330;T2:N=219),我们评估了任务最常用措施的内部(内部一致性)和时间(测试-重测可靠性)稳定性。我们表明,捕获灵活信念和行为适应的主要措施会产生良好的内部一致性和总体上令人满意的重测可靠性。然而,一些更复杂的灵活行为标记显示出较低的心理测量质量。我们的发现对使用此任务的先前研究的大量语料库具有意义,并为将来的研究中应该使用和不应该使用哪些措施提供了明确的指导。
    Rapid adaptation to sudden changes in the environment is a hallmark of flexible human behaviour. Many computational, neuroimaging, and even clinical investigations studying this cognitive process have relied on a behavioural paradigm known as the predictive-inference task. However, the psychometric quality of this task has never been examined, leaving unanswered whether it is indeed suited to capture behavioural variation on a within- and between-subject level. Using a large-scale test-retest design (T1: N = 330; T2: N = 219), we assessed the internal (internal consistency) and temporal (test-retest reliability) stability of the task\'s most used measures. We show that the main measures capturing flexible belief and behavioural adaptation yield good internal consistency and overall satisfying test-retest reliability. However, some more complex markers of flexible behaviour show lower psychometric quality. Our findings have implications for the large corpus of previous studies using this task and provide clear guidance as to which measures should and should not be used in future studies.

    在对知识进行标准化评估的同时,态度,与妊娠期糖尿病和高血压相关的实践(KAP)可以使用有效的工具,现有的研究仍然有限。这项前瞻性验证研究旨在开发和验证一种评估助产士和产科护士KAP的新工具。我们包括125名助产士和产科护士,他们通常为妊娠糖尿病和高血压患者提供护理。该工具表现出良好的内部一致性(Cronbach'salpha):知识(0.729,95%CI,0.654-0.776),态度(0.756,95%CI,0.690-0.814),和实践(0.925,95%CI,0.905-0.943)。难度指数(d)范围从0.38到0.99(知识),0.41至0.99(态度),和0.41至0.93(实践),指示适当的项目难度。歧视指数(D)确认项目可以区分知识水平低和高的受访者(D范围:知识0.02-0.77,0.06-0.64的态度,用于实践的0.20-0.84)。该工具的强大心理测量特性支持其在助产士和护士中与糖尿病和妊娠期高血压管理相关的KAP的未来研究中使用。该仪器在各种环境中都有可能具有价值,包括教育计划前的基线评估或干预后的学习成果评估。
    While standardized assessment of knowledge, attitudes, and practices (KAP) related to gestational diabetes and hypertension is possible with a valid tool, existing research remains limited. This prospective validation study aimed to develop and validate a novel tool to assess the KAP of midwives and obstetric nurses. We included 125 midwives and obstetric nurses who routinely care for patients with gestational diabetes and hypertension. The tool demonstrated good internal consistency (Cronbach\'s alpha): knowledge (0.729, 95% CI, 0.654-0.776), attitude (0.756, 95% CI, 0.690-0.814), and practices (0.925, 95% CI, 0.905-0.943). Difficulty indices (d) ranged from 0.38 to 0.99 (knowledge), 0.41 to 0.99 (attitudes), and 0.41 to 0.93 (practices), indicating appropriate item difficulty. Discrimination indices (D) confirmed items could differentiate between respondents with low and high knowledge levels (D range: 0.02-0.77 for knowledge, 0.06-0.64 for attitudes, 0.20-0.84 for practices). The robust psychometric properties of this tool support its use in future research on KAP related to diabetes and gestational hypertension management in midwives and nurses. This instrument has the potential to be valuable in various settings, including baseline assessment before educational programs or evaluation of learning outcomes after interventions.

    背景:虽然中重度TBI的情绪识别困难已得到证实,情感识别的标准措施极大地限制了可以得出的关于现实生活缺陷的结论。两项研究报告了甜食的发展,一种新的情感识别方法,试图克服这些限制。
    方法:这些研究旨在通过检查TBI组和匹配对照的表现来建立CAVEAT的心理测量特性,以提供其可靠性和有效性的估计(研究1),并比较TBI和对照组对CAVEAT情绪亚组的表现,该亚组代表了常规情绪研究中使用的六种基本情绪(研究2)。32名TBI参与者和32名匹配对照(研究1)以及16名TBI参与者和12名匹配对照(研究2)参与了这项研究。
    结果:CAVEAT表现出较高的结构效度和内部一致性。“基本”六种情绪亚组的表现与文献中报道的比率在很大程度上相似。
    结论:这些发现为CAVEAT的心理测量特性提供了一些证据,这表明它可以用作评估中重度TBI患者情绪识别的临床试验。
    BACKGROUND: While emotion recognition difficulties in moderate-severe TBI are well established, the standard measures of emotion recognition significantly limit the conclusions which can be drawn regarding real-life deficits. Two studies report on the development of CAVEAT, a new measure of emotion recognition that attempts to overcome these limitations.
    METHODS: These studies were designed to establish CAVEAT\'s psychometric properties by examining performance of a TBI group and matched controls in order to provide estimates of its reliability and validity (study 1), and to compare performance of the TBI and control groups on a subgroup of emotions from the CAVEAT that represented the six basic emotions used in conventional emotion research (study 2). Thirty-two participants with TBI and 32 matched controls (study 1) and 16 participants with TBI and 12 matched controls (study 2) participated in this study.
    RESULTS: CAVEAT demonstrated high construct validity and internal consistency. Performance on the subgroup of \"basic\" six emotions was largely similar to the rates reported in the literature.
    CONCLUSIONS: These findings provided some evidence for the psychometric properties of CAVEAT, indicating that it can be used as a clinical test for assessing emotion recognition in people with moderate-severe TBI.

    BACKGROUND: Substance use disorders (SUD) are associated with several neurobiological disruptions, including biases in attention and approach/avoidance behaviour. The aims of this study were to compare the strength of cognitive biases between light and problematic drinkers, to explore the role of IQ on the cognitive biases and to study the psychometric qualities of the measures.
    METHODS: Participants (N = 130) were divided into four groups based on IQ and severity of alcohol use-related problems: light (n = 28) and problematic drinkers (n = 25) with (sub)average IQ and light (n = 33) and problematic drinkers (n = 44) with mild to borderline intellectual disability (MBID). All participants performed the visual dot probe task and the approach avoidance task to measure the strength of cognitive biases.
    RESULTS: In contrast with the hypothesis, no cognitive biases were found in problematic drinkers. Full scale IQ nor level of craving influenced the strength of the cognitive biases in light and problematic drinkers, although IQ did influence task performance (i.e. large intra-individual, trial-to-trial variation in reaction time). The internal consistency of the visual dot probe task was good, whereas the internal consistency of the approach avoidance task was poor.
    CONCLUSIONS: Cognitive biases seem to vary within the group of problematic drinkers as a whole. The psychometric qualities of the measures are problematic, especially in relation to the intra-individual variability in reaction time found in participants with MBID. Until the implications of this variability on the validity of implicit measures and establishing bias scores are more clear, the use of these measures in individuals with MBID calls for scrutiny.
