Asymptotic comparison of missing data procedures for estimating factor loadings

Large sample properties of four methods of handling multivariate missing data are compared. The criterion for comparison is how well the loadings from a single factor model can be estimated. It is shown that efficiencies of the methods depend on the pattern or arrangement of missing data, and an evaluation study is used to generate predictive efficiency equations to guide one's choice of an estimating procedure. A simple regression-type estimator is introduced which shows high efficiency relative to the maximum likelihood method over a large range of patterns and covariance matrices.     

The Role of Experiencing in Psychotherapy: Attending to the “Bodily Felt Sense” of a Problem Makes Any Orientation More Effective

Focusing-Oriented Theory defines a new aspect of client experiencing – the bodily felt sense of a situation or problem. The felt sense is vague at first, sensed directly but not yet in explicit words or images. It is neither drowning in strong emotions nor is it just thinking. The chapter shows examples of how to help a client find this level and how to respond to it. When the felt sense is responded to little steps inwardly arise directly from the client's own process. It is proposed that the Philosophy of the Implicit which underlies this model, can unify our different orientations by showing us how to use any theory experientially. The client is always invited to check any therapist suggested move for resonance in the body and a sense of life being carried forward.     

Emotional Triggers and Psychopathology Associated with Suicidal Ideation in Urban Children with Elevated Aggressive-Disruptive Behavior

8.6% suicidal ideation (SI) was found among 349 urban 6–9 year olds in the top tercile of aggressive-disruptive behavior. SI was associated with more self-reported depression, ODD, conduct problems, and ADHD symptoms (ES 0.70–0.97) and 3.5–5 times more clinically significant symptoms. Parents rated more symptoms in older children associated with SI compared to parents of similar age children without SI, including greater somatic and behavior problems in 8–9 year olds with SI. Parent ratings did not differentiate SI and non-SI in 6–7 year olds. SI frequently co-occurred with thoughts about death. Children described anger, dysphoria and interpersonal conflict as motivators/triggers for SI and worries about safety/health as motivator/triggers for thoughts about death, suggesting that problems managing emotionally challenging situations are a specific factor in initiating SI. Universal and indicated interventions for children to strengthen emotional self-regulation and behavioral control are recommended to complement the current emphasis on suicide prevention among adolescents.     

Beyond the Big Five: Leader Goal Orientation as a Predictor of Leadership Effectiveness

This study examined proximal traits as mediators of the relationships between distal traits and leadership effectiveness. Specifically, we examined goal orientation, leadership self-efficacy, and motivation to lead (MTL) as antecedents of leadership effectiveness, after controlling for the Big Five personality traits. We tested our hypotheses with a sample of 100 leaders of four-person teams performing a manufacturing task in a laboratory setting. Consistent with expectation, leadership self-efficacy partially mediated the relationships between learning goal orientation and Affective-Identity MTL as well as Social-Normative MTL, after controlling for the Big Five. Noncalculative MTL related significantly to averaged team member ratings of leadership effectiveness, after controlling for both the leader's and the team member's personality. These results help aid in our understanding of why leader traits relate to leadership effectiveness.     

Hierarchical modeling of sequential behavioral data: an empirical Bayesian approach

The authors review the common methods for measuring strength of contingency between 2 behaviors in a behavioral sequence, the binomial z score and the adjusted cell residual, and point out a number of limitations of these approaches. They present a new approach using log odds ratios and empirical Bayes estimation in the context of hierarchical modeling, an approach not constrained by these limitations. A series of hierarchical models is presented to test the stationarity of behavioral sequences, the homogeneity of sequences across a sample of episodes, and whether covariates can account for variation in sequences across the sample. These models are applied to observational data taken from a study of the behavioral interactions of 254 couples to illustrate their use.

Hierarchical modeling of sequential behavioral data: examining complex association patterns in mediation models

This article presents new methods for modeling the strength of association between multiple behaviors in a behavioral sequence, particularly those involving substantively important interaction patterns. Modeling and identifying such interaction patterns becomes more complex when behaviors are assigned to more than two categories, as is the case for most observational research. The authors propose multilevel empirical Bayes methods to overcome the challenges inherent in such data. Furthermore, these methods allow the study of how variation in interaction patterns can mediate the effects of antecedents or intervention on distal outcomes. New procedures are developed to compare alternative mediation models and pinpoint which random effects operate as mediators. These models are then applied to observational data taken from a study of the behavioral interactions of 254 couples.
