Uncertainty and risk during the COVID-19 pandemic: A latent profile analysis

In the present study, we examine how subgroups of people are characterized by different profiles of uncertainty surrounding COVID-19, susceptibility, and recovery. Participants (N = 199) were U.S. residents recruited online for a longitudinal study during the summer of 2020. We first, identified groups using latent profile analysis (LPA) and then examined whether these profiles predicted differences in COVID-related risky and preventative behaviors. LPA identified five distinct profiles of people representing a combination of low and high uncertainty and low, moderate, and high risk perceptions. Results revealed that latent-profile group membership predicted intention to interact with others outside of the household, intention to engage in non-essential shopping, intention to attend an in-person religious gathering, intention to wear a mask in public, and self-reported physical distancing in the past week. Profile membership did not predict intentions to: dine out, go to the nail/hair salon, go to the gym, nor physically distance from others in the future, nor did it predict handwashing in the past week.     

父母教养方式的潜在类别:潜在剖面分析

采用问卷法,对764名青少年进行测试,首先采用潜在剖面分析模型探索了父母教养方式的潜在类别,然后通过青少年道德脱离、道德同一性的得分差异来确认潜在类别的效度。结果表明,从青少年的角度父母教养方式分为积极型、消极型和混合型三种,其中积极型人数最多、消极型人数最少。此外,青少年道德脱离、道德同一性的得分在这三种潜在类别上存在显著差异,表明本研究得到的三种潜在类别有较好的效度。积极型教养方式下青少年道德脱离的得分显著低于混合型和消极型的得分,混合型教养方式下道德脱离的得分显著高于消极型的得分;积极型教养方式下青少年道德同一性的得分显著高于混合型和消极型的得分,混合型教养方式下道德同一性的得分显著低于消极型的得分。     

How perceived changes in the ethical culture of organizations influence the well-being of managers: a two-year longitudinal study

The first aim of this study was to identify long-term patterns of ethical organizational culture based on the perceptions of 368 Finnish managers over a period of two years. The second aim was to investigate whether there is a difference in the long-term occupational well-being (burnout and work engagement) of managers exhibiting different patterns of ethical culture. Based on latent profile analysis, five different patterns of the strength of ethical culture were identified: moderate, high, increasing, decreasing, and low. The results show that managers exhibiting either the low or decreasing pattern of ethical culture experienced significant changes in their well-being over time. Decreasing or permanently low ethical culture was related to increased cynical attitudes towards work, and to decreased work engagement. On the positive side, stably high ethical culture was associated with enduringly high levels of well-being over time. In sum, low or decreasing ethical culture poses a risk to occupational well-being, whereas an organization with a culture that is perceived as permanently strong represents a favourable work environment.     

Testing the identity of trends under the restriction of monotonicity in repeated measures designs

Procedures are described for the analysis of profiles of means in repeated measures designs under order restriction for patterns of mean change. The exact likelihood ratio is derived for the case of two groups of subjects, and a computationally simple alternative to the exact likelihood ratio test is provided for designs involving more than two groups. Tables of critical values are provided for the case of simple-order alternatives.The author wishes to thank Joseph C. Saunders for his editorial assistance.     

The nontruncated marginal of a truncated bivariate normal distribution

Inference is considered for the marginal distribution ofX, when (X, Y) has a truncated bivariate normal distribution. TheY variable is truncated, but only theX values are observed. The relationship of this distribution to Azzalini's skew-normal distribution is obtained. Method of moments and maximum likelihood estimation are compared for the three-parameter Azzalini distribution. Samples that are uniformative about the skewness of this distribution may occur, even for largen. Profile likelihood methods are employed to describe the uncertainty involved in parameter estimation. A sample of 87 Otis test scores is shown to be well-described by this model.     

Latent Profiles of Comorbid Depression as Predictors of PTSD Treatment Outcome

Posttraumatic stress disorder (PTSD) frequently co-occurs with major depressive disorder, and empirically supported PTSD treatments consistently improve depression. However, both diagnoses are heterogeneous and specific patterns of symptom overlap may be related to worse treatment outcome. Two hundred individuals with chronic PTSD participated in a doubly randomized preference trial comparing prolonged exposure and sertraline. Latent Profile Analysis was used to identify classes based on PTSD and depression symptoms prior to starting treatment. A three-class model best fit the data, with a high depression and PTSD severity class (distressed), a moderate depression and low PTSD avoidance class (depressive), and a low depression and high PTSD avoidance class (avoidant). The avoidant class showed the lowest rates of major depressive disorder diagnosis and transdiagnostic vulnerabilities to depression. Patients in the distressed class experienced more robust PTSD treatment response, with no differences between prolonged exposure and sertraline. These findings highlight the role of avoidance in nondepressed PTSD presentations while also demonstrating that co-occurring depression is not contraindicated in evidence-based PTSD treatment.

Evidence for discrete profiles of children’s physiological activity across three neurobiological system and their transitions over time

The conceptualization of stress‐responsive physiological systems as operating in an integrated manner is evident in several theoretical models of cross‐system functioning. However, limited empirical research has modeled the complexity of multisystem activity. Moreover few studies have explored developmentally regulated changes in multisystem activity during early childhood when plasticity is particularly pronounced. The current study used latent profile analysis (LPA) to evaluate multisystem activity during fall and spring of children's transition to kindergarten in three biological systems: the parasympathetic nervous system (PNS), sympathetic nervous system (SNS), and hypothalamic pituitary adrenal (HPA) axis. Latent transition analysis (LTA) was then used to examine the stability of profile classification across time. Across both timepoints, three distinct profiles of multisystem activity emerged. One profile was characterized by heightened HPA axis activity (HPA Axis Responders), a second profile was characterized by moderate, typically adaptive patterns across the PNS, SNS, and HPA axis (Active Copers/Mobilizers), and a third profile was characterized by heightened baseline activity, particularly in the PNS and SNS (Anticipatory Arousal/ANS Responders). LTA of fall‐to‐spring profile classifications indicated higher probabilities that children remained in the same profile over time compared to probabilities of profile changes, suggesting stability in certain patterns of cross‐system responsivity. Patterns of profile stability and change were associated with socioemotional outcomes at the end of the school year. Findings highlight the utility of LPA and LTA to detect meaningful patterns of complex multisystem physiological activity across three systems and their associations with early adjustment during an important developmental transition.
