Idiographic network models based on time‐series data have received recent attention for their ability to model relationships among symptoms and behaviours as they unfold in time within a single individual (cf. Epskamp, Borsboom, & Fried, 2018; Fisher, Medaglia, & Jeronimus, 2018). Rather than examine the correlational relationships between variables in a sample of individuals, an idiographic network examines correlations within a single person, averaged over many time points. Because the approach averages over time, the data must be stationary (i.e. relatively consistent over time). If individuals experience varying states over time—different mixtures of symptoms and behaviours in one moment or another—then averaging over categorically different moments may undermine model accuracy. Fisher and Bosley (2019) address these concerns via the application of Gaussian finite mixture modelling to identify latent classes of time points in intraindividual time‐series data from a sample of adults with major depressive disorder and/or generalised anxiety disorder (n = 45). The present paper outlines an extension of this work, wherein network analysis is used to model within‐class covariation of symptoms. To illustrate this approach, network models were constructed for each intraindividual class identified by Fisher and Bosley (137 networks across the 45 participants, mean classes/person = ~3, range = 2–4 classes/person). We examine the relative consistency in symptom organisation between each individual's multiple mood state networks and assess emergent group‐level patterns. We highlight opportunities for enhanced treatment personalisation and review nomothetic patterns relevant to transdiagnostic conceptualisations of psychopathology. We address opportunities for integrating this approach into clinical practice and outline potential shortcomings. 相似文献

The currently available distribution-free confidence interval for a difference of medians in a within-subjects design requires an unrealistic assumption of identical distribution shapes. A confidence interval for a general linear function of medians is proposed for within-subjects designs that do not assume identical distribution shapes. The proposed method can be combined with a method for linear functions of independent medians to provide a confidence interval for a linear function of medians in mixed designs. Simulation results show that the proposed methods have good small-sample properties under a wide range of conditions. The proposed methods are illustrated with examples, and R functions that implement the new methods are provided. 相似文献

The current study examined unfolding relations among mothers’ mindful parenting, parent–adolescent recurrent conflict, and adolescents’ externalizing and internalizing problems. In a community sample of 117 families (31% black, Asian, American Indian, or Latino), parents and adolescents (52% female; average age = 12.13 years) were followed over 15 months. Parents answered questions about mindful parenting and recurrent conflict, and adolescents reported on their own externalizing and internalizing problems. Path analyses indicated that higher levels of mindful parenting were significantly related to lower levels of recurrent conflict 2–3 months later, controlling for previous levels of recurrent conflict. Moreover, lower levels of recurrent conflict were significantly related to lower levels of externalizing problems and internalizing problems 1 year later, controlling for previous levels of those problems. Subgroup analyses indicated that relations were comparable across subgroups defined by adolescent gender, race, parent marital status, and family financial strain. The effects of mindful parenting were robust even after accounting for other indicators of positive and supportive parenting, namely inductive reasoning and warmth in the parent–adolescent relationship. These findings highlight the potential of mindful parenting to improve family interactions and adolescent adjustment. 相似文献

This study examined a moderated mediation model testing whether dysmorphic concern is related to behaviour altered to change appearance. This relationship is potentially mediated by depressive symptomatology (dysphoria and self-esteem) and ideas of reference about “laughing, commenting” and “attention, appearance,” and each mediated relationship moderated by sex. The sample was made up of 3377 adolescents from 12 to 18 years old (Mage = 14.52; SD = 1.65, 56.5% girls). The results showed that dysphoria and ideas of reference about “laughing, commenting” and “attention, appearance” partially mediated the relationship between dysmorphic concern and behavioural impairment related to body image. The relationship with dysphoria was moderated by sex, such that the mediation effect was stronger in girls than in boys. This result implies that girls who are worried about some characteristic of their appearance and show dysphoria are at greater risk of altered behaviour involving avoidance or controlling their appearance than boys. In addition, a possible risk of body dysmorphic disorder (3.45% of the sample) was found, with very prominent hiding behaviour using clothing or control behaviours, such as frequent weighing and looking at oneself in the mirror too much. Implications of these findings are discussed. 相似文献

This article calls attention to an important, yet neglected, subset of medieval Latin sources: the dozens upon dozens of works of late antique and early Byzantine Christian Greek authors translated into Latin between the second and the thirteenth centuries. It also introduces a new initiative to study these sources: The Lost Patriarchs Project. The goal of this article is threefold. First, it presents a sample of the deep, virtually untouched reservoir of medieval Latin texts that have Greek origins, including patristics, hagiography, and apocrypha, and marshals evidence for their use among medieval readers. Second, it considers some of the reasons why this corpus of medieval Latin literature has not been subject to critical inquiry. Third, it announces plans for a new instrument of reference tentatively entitled The Lost Patriarchs: A Survey of the Greek Fathers in the Medieval Latin Tradition. A reference tool of this kind would gather all that is known about these texts in current scholarship, allowing future researchers to begin the work of creating critical editions of them and incorporating them into our understanding of medieval thought. 相似文献

Theory and research on self‐regulation, emotional adjustment, and interpersonal processes focus increasingly on parasympathetic functioning, using measures of vagally mediated heart rate variability (vmHRV) or respiratory sinus arrhythmia (RSA). This review describes models of vmHRV in these areas, and issues in measurement and analysis. We propose a framework organizing theory and research as examining (a) vmHRV as an individual difference or a situational response, and (b) resting, reactive, or recovery levels. Evidence supports interpretation of individual differences in resting vmHRV as a broad biomarker for adaptive functioning, but its specificity and underlying mechanisms require elaboration. Individual differences in vagal reactivity (i.e., trait‐like differences in vmHRV decreases during challenge or stress) are less commonly studied in adults and results are mixed. Many stressors and challenges evoke temporary decreases in vmHRV, and in some research self‐regulatory effort evokes increases. In a smaller literature, positive interpersonal experiences and some restorative processes increase resting vmHRV, whereas depletion of self‐regulatory capacity through related effort decreases it. Greater attention to conceptual distinctions regarding vmHRV constructs and several methodological issues will strengthen future research. Importantly, researchers should exercise caution in equating vmHRV with specific psychosocial constructs, especially in the absence of converging assessments and precise experimental manipulations. 相似文献
