Studying Multivariate Change Using Multilevel Models and Latent Curve Models

In longitudinal research investigators often measure multiple variables at multiple points in time and are interested in investigating individual differences in patterns of change on those variables. In the vast majority of applications, researchers focus on studying change in one variable at a time. In this article we consider methods for studying relations1.1ips between patterns of change on different variables. We show how the multilevel modeling framework, which is often used to study univariate change, can be extended to the multivariate case to yield estimates of covariances of parameters representing aspects of change on different variables. We illustrate this approach using data from a study of physiological response to marital conflict in older married couples, showing a substantial correlation between rate of linear change on different stress-related hormones during conflict. We also consider how similar issues can be studied using extensions of latent curve models to the multivariate case, and we show how such models are related to multivariate multilevel models.     

Abstract: Local Influence and Robust Methods for Mediation Models

Mediation analysis investigates how certain variables mediate the effect of predictors on outcome variables. Existing studies of mediation models have been limited to normal theory maximum likelihood (ML) or least squares with normally distributed data. Because real data in the social and behavioral sciences are seldom normally distributed and often contain outliers, classical methods can result in biased and inefficient estimates, which lead to inaccurate or unreliable test of the meditated effect. The authors propose two approaches for better mediation analysis. One is to identify cases that strongly affect test results of mediation using local influence methods and robust methods. The other is to use robust methods for parameter estimation, and then test the mediated effect based on the robust estimates. Analytic details of both local influence and robust methods particular for mediation models were provided and one real data example was given. We first used local influence and robust methods to identify influential cases. Then, for the original data and the data with the identified influential cases removed, the mediated effect was tested using two estimation methods: normal theory ML and the robust method, crossing two tests of mediation: the Sobel (1982) Sobel, M. E. 1982. “Asymptotic confidence intervals for indirect effects in structural equation models”. In Sociological methodology, Edited by: Leinhardt, S. 290–312. Washington, DC: American Sociological Association. [Crossref] , [Google Scholar] test using information-based standard error (z _I ) and sandwich-type standard error (z _SW ). Results show that local influence and robust methods rank the influence of cases similarly, while the robust method is more objective. The widely used z _I statistic is inflated when the distribution is heavy-tailed. Compared to normal theory ML, the robust method provides estimates with smaller standard errors and more reliable test.     

Studying Emotions in Security and Diplomacy: Where We Are Now and Challenges Ahead

The core objective of this special issue has been to shed light on emotions as (1) frames that shape interpersonal diplomatic relations, (2) as key tools that are used as part of the statecraft's toolbox, and (3) as formative/productive dynamics with real effects on human beings—that, in turn, often construct and maintain conflicts. It is therefore pertinent that we interrogate the political psychology of individual, collective, mass, and communal emotions and how these are often (mis)used in diplomacy and security narratives to legitimize politicians' decisions and practices. This concluding article provides a state of the art account of the study of emotions in International Relations (IR), sums up the main findings from all special issue contributions and constructively explores potential challenges ahead for the study of emotions in IR, especially in security and diplomacy studies. It concludes with an appeal for the development of a multiperspective approach—that is, one that combines social sciences, natural sciences, and humanities—for a nuanced study of the role of emotional work in state, diplomatic as well as security narratives and practices. This approach will in turn require methodological pluralism in how we go about, as reflexive researchers, our emotional research.     

Studying the Dynamics of Problem Behavior Across Multiple Time Scales: Prospects and Challenges

As a commentary on the Special Issue, this paper discusses recent advances in the study of change across several time scales. It points out the importance of specifying time scales and putative patterns of change when characterizing problem behavior over developmental time scales. Methods for studying risk and protective mechanisms through observation of social interaction are also discussed as a way to study influences that operate in real time. Methods for studying episode-level interaction patterns that result from such real-time influences are also discussed, along with ways to integrate these with longitudinal assessments to study the effects of social interaction on problem behavior across developmental time scales.     

Multi-domain Models of Risk Factors for Depression and Anxiety Symptoms in Preschoolers: Evidence for Common and Specific Factors

Relatively few studies have examined multiple pathways by which risk factors from different domains are related to symptoms of anxiety and depression in young children; even fewer have assessed risks for these symptoms specifically, rather than for internalizing symptoms in general. We examined a theoretically- and empirically-based model of variables associated with these symptom types in a diverse community sample of 796 4-year-olds (391 boys, 405 girls) that included factors from the following domains: contextual (SES, stress and family conflict); parent characteristics (parental depression); parenting (support/engagement, hostility and scaffolding); and child characteristics including negative affect (NA) effortful control (EC) sensory regulation (SR), inhibitory control (IC) and attachment. We also compared the models to determine which variables contribute to a common correlates of symptoms of anxiety or depression, and which correlates differentiate between those symptom types. In the best-fitting model for these symptom types (a) SES, stress and conflict had indirect effects on both symptom types via long-chain paths; (b) caregiver depression had direct effects and indirect ones (mediated through parenting and child effortful control) on both symptom types; (c) parenting had direct and indirect effects (via temperament and SR); and temperament had direct effects on both symptom types. These data provide evidence of common risk factors, as well as indicate some specific pathways/mediators for the different symptom types. EC was related to anxiety, but not depression symptoms, suggesting that strategies to improve child EC may be particularly effective for treatment of anxiety symptoms in young children.

Borderline Personality Disorder in 3-D: Dimensions,Symptoms, and Measurement Challenges

Borderline personality disorder (BPD) is a pervasive pattern of psychopathology characterized by unstable affect, suicidal behaviors, and identity problems (Diagnostic and statistical manual of mental disorders. Washington, DC: Author; 2000). BPD is heterogeneous in nature, highly prevalent in clinical settings, and increasingly studied by clinical and social psychologists. This review highlights affective instability, impulsivity, and interpersonal hypersensitivity, the interaction of which we believe accounts for the symptoms of BPD, the BPD criteria most associated with these features, and the interrelationships among these underlying dimensions. We also discuss difficulties in measurement of these dimensions. Real-world assessment methods will assist in the measurement of time-dependent processes and identify causes, covariates, or consequences of these processes to determine how these features manifest themselves in real life.     

Help-Seeking Comfort and Receiving Social Support: The Role of Ethnicity and Context of Need

Examined help-seeking comfort and receiving social support among Latinos, African Americans, and European Americans across two contexts: in a communitywide emergency (Hurricane Andrew) and 2 years later in a nonemergency situation. In general, help-seeking comfort was a strong predictor of received support. Notwithstanding many similarities between the groups, the effects of ethnicity differed according to the context. In emergency, all groups reported similarly high levels of help-seeking comfort and received support. In nonemergency, help-seeking comfort declined for blacks and whites but not for Latinos. Although all ethnic groups reported receiving less social support in nonemergency, the decline in received support across contexts was most dramatic for Latinos. Situational, cultural, and differential resource loss explanations are offered to account for the findings.     

Depressive Symptoms Among Delinquent Youth: Testing Models of Association with Stress and Support

The high prevalence of depression among incarcerated youth indicates a need to better understand factors that contribute to depression within this vulnerable subgroup. Previous research in general community samples has suggested that high levels of stress and low levels of parental support are associated with depression in young people, but it is unclear whether or how they might be associated with depression among incarcerated youth who are already vulnerable. Using a sample of 228 adolescents (aged 13–18 years) who were detained in the juvenile justice system, stress and support were modeled as independent main effects and as interactive risk factors in relation to depressive symptoms. More stressful life events and less caregiver support were each independently associated with depressive symptoms, but no evidence was found for the buffering hypothesis in this sample. Stressful life events were more strongly associated with depressive symptoms among boys compared to girls.

Cognitive Enhancement: Methods, Ethics, Regulatory Challenges

Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.

Competency‐based Models of Supervision: Principles and Applications,Promises and Challenges

Major changes initiated by the Psychology Board of Australia (the Board) and by professional bodies both nationally and internationally have placed professional supervision in the spotlight for the practising psychologist and supervisor. Further, within the context of a growing impetus towards competency‐based pedagogies for professional training across disciplines, a recent Board document has indicated that supervisor training must adhere to a competency‐based model within a best‐practice supervision framework (Psychology Board of Australia). For the practising psychologist, the recent recommendation closely follows other initiatives including the introduction of mandatory peer consultation and supervisor accreditation. The current article seeks to clarify for the Australian psychologist the characteristics of competency‐based supervision models for training and supervision, and to unpack the many implications for professional practice. The article outlines the features that distinguish competency models from other supervision models, explains the rationale for and the merits that competency‐driven pedagogies promise, and discusses the challenges these changes will bring to supervision theory and practice.
