潜在增长模型已成为国外纵向研究的有力分析工具。通过对国外抑郁症状纵向研究及潜在增长模型应用研究的整理,发现患者抑郁症状的变化轨迹存在个体差异,但其中又存在相似特征,根据这些特征可以将抑郁症状的变化轨迹主要分为四种,早期症状快速减少、治疗期间症状缓慢平稳减少、早期症状减少后期出现反弹和症状未出现明显变化。通过总结该模型在抑郁症状研究领域的应用成果,了解抑郁症患者抑郁症状变化的情况,以期为我国相关研究的进一步开展提供新思路。

孤独症谱系障碍(Autism Spectrum Disorder, ASD)早期识别有助于早期诊断和早期干预的实施, 对于改善ASD儿童发育结果至关重要。高风险前瞻性纵向研究以高风险婴儿(ASD儿童的年幼同胞, 入组年龄小于12个月)作为主要研究对象, 通过对ASD高风险婴儿(24至36个月之间诊断为ASD的高风险婴儿)的早期发育轨迹的描绘和核心症状早期表现的识别, 为ASD早期识别提供了重要依据。未来可以增加被试数量、延长观察时间并密集观察时间点、关注伴发障碍、综合考虑遗传、环境和文化因素影响, 并结合早期干预研究进行深入探索。未来在中国开展相关研究具有重要的科学价值和临床意义。 相似文献

经验取样法是一种有效的密集纵向研究数据收集方法。该方法的优点正逐渐被广大研究者所认同,国外运用经验取样法取得的研究成果越来越多,而国内学者对经验取样法的研究尚处于探索阶段,运用此方法的实证研究更是凤毛麟角。通过对《应用心理学期刊》(Journal of Applied Psychology)最近5年(2010~2014年)发表的26篇采用经验取样法的实证研究论文的内容分析,发现这些文章全面体现了经验取样法的特点、研究内容、样本量、激励方式、数据收集和操作过程等该方法的操作要素。对其进行总结不仅有利于对经验取样法在组织行为学中的应用状况进行总结,而且也能促进这一方法在未来的组织行为学和人力资源管理中的发展和应用。 相似文献

Previous theory and research suggest that team reflection is beneficial for team performance. We argue that results remain inconclusive because prior studies have not accounted for the dynamic nature of this relationship. This paper addresses this research gap by examining time-specific relationships among variables and the intra-team variability of changes across time. In a four-wave longitudinal field study with 97 teams (N = 453 team members) performing a business simulation task, short-term (i.e., autoregressive, cross-lagged effects) and long-term (i.e., latent trajectories) relationships between team reflection and performance were explored. We found evidence that reflection had negative autoregressive effects and that there were direct positive short-term relationships between reflection and performance. Reflection trajectories were seen to decline across time and performance trajectories to increase across time. In addition, teams with either low initial reflection or low initial performance showed higher increases in reflection across time, whilst higher increase in reflection was negatively related to change in performance. Findings are discussed with respect to how they extend the previous literature and what directions they suggest for future research. 相似文献

本研究旨在考察初中生心理素质的发展轨迹以及亲子和同伴依恋对其的影响。三所中学的442名初一学生和501名初二学生参加了三轮追踪调查,初测平均年龄M =12.83,SD =0.74。结果发现,初一学生,心理素质发展轨迹可分为中-降组（79%）和高-升组（21%）两个亚群组;且初一上父子依恋或母子依恋水平越高,心理素质发展轨迹为高-升组的概率大于中-降组。初二学生,心理素质发展轨迹可分为低-稳组（84%）和高-升组（16%）两个亚群组;且初二上父子依恋水平越高,心理素质发展轨迹为高-升组的概率大于低-稳组。结果表明初中生心理素质发展轨迹可以分为不同的亚群组类型,父子依恋和母子依恋对初中生心理素质发展有积极作用,这些发现对于初中生心理素质的培养具有一定的指导意义。 相似文献

追踪研究当中, 交叉滞后模型可以探究多变量之间往复式影响, 潜增长模型可以探究个体增长趋势。对两类模型进行整合, 例如同时关注往复式影响与个体增长趋势, 同时可以定义测量误差、随机截距等变异成分, 衍生出随机截距交叉滞后模型、特质-状态-误差模型、自回归潜增长模型、结构化残差潜增长模型等。以交叉滞后模型和潜增长模型分别作为基础模型, 从个体间/个体内变异分解的角度对上述各类模型梳理, 整合出此类模型的分析框架, 并拓展建立“因子结构化潜增长模型(factor latent curve model with structured reciprocals)”作为统合框架。通过实证研究(早期儿童的追踪研究-幼儿园版, ECLS-K), 建立21049名儿童的阅读和数学能力的往复式影响与增长趋势。研究发现, 分离了稳定特质的模型拟合最优。研究也对模型建模思路和模型选择提供了建议。 相似文献

We responded to the need for replication in psychotherapy research by extending a prior naturalistic study documenting the effectiveness of long-term psychodynamic treatment. We employed three novel analytic strategies and evaluated their influence on substantive interpretations offered in the prior study. The sample consisted of clients (N = 387; Mage = 31.61; SD = 11.13; 58.9% female; 79.1% Caucasian/White) receiving outpatient treatment at a psychodynamic training clinic. Results replicated the original two-class solutions for social functioning, depression and life satisfaction. Novel to the replication analyses, each trajectory for social functioning and depression exhibited nonlinear change and results advanced research on a theorised mechanism of effective psychodynamic treatment. Results showed that change in experiential avoidance was a possible mechanism between early-treatment change in social functioning and later-treatment changes in depression symptoms and life satisfaction. Clinical implications focus on the influence that initial levels of symptoms and well-being may have on early and later phases of treatment, monitoring progress throughout treatment, and how to promote symptom and well-being improvement. 相似文献

Preliminary evidence suggests that changes in DNA methylation, a widely studied epigenetic mechanism, contribute to the etiology of Autism Spectrum Disorder (ASD). However, data is primarily derived from post-mortem brain samples or peripheral tissue from adults. Deep-phenotyped longitudinal infant cohorts are essential to understand how epigenetic modifications relate to early developmental trajectories and emergence of ASD symptoms. We present a proof-of-principle study designed to evaluate the potential of prospective epigenetic studies of infant siblings of children with ASD.Illumina genome-wide 450 K DNA methylation data from buccal swabs was generated for 63 male infants at multiple time-points from 8 months to 2 years of age (total N = 107 samples). 11 of those infants received a diagnosis of ASD at 3 years. We conducted a series of analyses to characterize DNA methylation signatures associated with categorical outcome and neurocognitive measures from parent-report questionnaire, eye-tracking and electro-encephalography.Effects observed across the entire genome (epigenome-wide association analyses) suggest that collecting DNA methylation samples within infant-sibling designs allows for the detection of meaningful signals with smaller sample sizes than previously estimated. Mapping networks of co-methylated probes associated with neural correlates of social attention implicated enrichment of pathways involved in brain development. Longitudinal modelling found covariation between phenotypic traits and DNA methylation levels in the proximity of genes previously associated with cognitive development, although larger samples and more complete datasets are needed to obtain generalizable results.In conclusion, assessment of DNA methylation profiles at multiple time-points in infant-sibling designs is a promising avenue to comprehend developmental origins and mechanisms of ASD. 相似文献
