Mixture Modeling Methods for the Assessment of Normal and Abnormal Personality,Part I: Cross-Sectional Models

Over the past 75 years, the study of personality and personality disorders has been informed considerably by an impressive array of psychometric instruments. Many of these tests draw on the perspective that personality features can be conceptualized in terms of latent traits that vary dimensionally across the population. A purely trait-oriented approach to personality, however, might overlook heterogeneity that is related to similarities among subgroups of people. This article describes how factor mixture modeling (FMM), which incorporates both categories and dimensions, can be used to represent person-oriented and trait-oriented variability in the latent structure of personality. We provide an overview of different forms of FMM that vary in the degree to which they emphasize trait- versus person-oriented variability. We also provide practical guidelines for applying FMM to personality data, and we illustrate model fitting and interpretation using an empirical analysis of general personality dysfunction.     

Introduction to the Special Section on Mixture Modeling in Personality Assessment

Latent variable models offer a conceptual and statistical framework for evaluating the underlying structure of psychological constructs, including personality and psychopathology. Complex structures that combine or compare categorical and dimensional latent variables can be accommodated using mixture modeling approaches, which provide a powerful framework for testing nuanced theories about psychological structure. This special series includes introductory primers on cross-sectional and longitudinal mixture modeling, in addition to empirical examples applying these techniques to real-world data collected in clinical settings. This group of articles is designed to introduce personality assessment scientists and practitioners to a general latent variable framework that we hope will stimulate new research and application of mixture models to the assessment of personality and its pathology.     

Family social support during the predeparture period: The experience of British migrants

This study explored the stress, wellbeing and social support of predeparture British migrants to New Zealand. The main research questions addressed the relationship between family support and psychological outcomes, differences in migration desire between couples, and the impact of extended family support. A survey recruited 95 participants from online forums for migrants to New Zealand and results indicated that support from immediate family was related to better wellbeing and lower stress. Migrants who considered themselves the driving force behind the move reported significantly more stress and less family support than migrants who had partners who were equally enthusiastic about the move abroad. Sojourners perceived more support from extended family than did migrants who intended to leave permanently. The most difficult parts of the migration process were leaving loved ones, logistical demands, and uncertainty. The most positive parts of the process were adventure and becoming closer as a family. Overall, migration stress and coping began well before departure from the country of origin.     

Toward an Understanding of the Connections in Creating Lasting Family Connections

Abstract

The Creating Lasting Family Connections^® (CLFC) program is designed to help improve relationship skills and reduce antisocial behaviors. Strader and colleagues propose that prosocial connectedness is responsible for program outcomes. We propose that the intersection of high agreeableness and low impulsivity represent an operational definition. We examined this definition in the context of a RCT with 246 men in prison reentry. CLFCFP increased the number of connected individuals. Being connected and the program independently impacted relationship skills, but no evidence was found to support the hypothesis that the program impacts would be more pronounced among those who were connected.     

The development of the experience and anticipation of regret

Although recent studies have established that children experience regret from around 6 years, we do not yet know when the ability to anticipate this emotion emerges, despite the importance of the anticipation of regret in decision-making. We examined whether children will anticipate they will feel regret if they were to find out in a box-choosing game that, had they made a different choice, they would have obtained a better prize. Experiment 1 replicated Guttentag and Ferrell's study in which children were asked what they hoped was in a non-chosen box. Even 8- to 9-year olds find this question difficult. However, when asked what might make them feel sadder, 7- to 8-year olds (but not younger children) predicted that finding the larger prize in the unchosen box would make them feel this way. In Experiments 2 and 3, children predicted how they would feel if the unchosen box contained either a larger or smaller prize, in order to examine anticipation of both regret and of relief. Although 6- to 7-year olds do experience regret when they find out they could have won a better prize, they do not correctly anticipate feeling this way. By around 8 years, the majority of children are able to anticipate both regret and relief.     

Retrieval of bindings between task-irrelevant stimuli and responses can facilitate behaviour under conditions of high response certainty

Repetition priming can be driven by the encoding and retrieval of stimulus–response (S–R) bindings. When a previously encoded S–R binding is retrieved, and is congruent with the response currently required, it can bias response-selection processes towards selecting the retrieved response, resulting in facilitation. Previous studies have used classification tasks at retrieval. Here, two (or more) response options are competing, and it is likely that any evidence (e.g., an S–R binding) in favour of one option will be utilized to effect a decision. Thus, S–R effects are likely to be seen when using such a task. It is unclear whether such effects can be seen under conditions of higher response certainty, when participants are explicitly cued to make a response. Across two experiments, evidence for a modulating influence of S–R bindings is seen despite using a response cueing method at retrieval to minimize response uncertainty and despite stimuli being task irrelevant. Finally, the results suggest that responses within these S–R bindings are coded at the level of left versus right hand, and not a more fine-grained within-hand thumb versus index finger. The results underline the resilience of S–R effects, suggesting that they are present even under conditions where no explicit object-oriented decision is required.     

Is regret for inaction relatively self‐enhancing?

Previous accounts of regret suggest that people report greater regret for inaction than for action because the former is longer lasting and more painful than the latter. We suggest instead that the tendency for people's greatest regrets to concern inaction more than action may be due to the relatively self‐enhancing nature of regrets for inaction. In Study 1 we asked people to think about their greatest recent regret and to code it as being due to action or inaction. In Study 2 participants described their greatest regret from across their entire life. In both studies we observed an inaction effect only amongst individuals high in self‐esteem (HSE). In Study 2 we found that the inaction effect was confined to HSE people whose greatest regret was personal in nature. These results support the claim that regret for inaction is relatively self‐enhancing and suggest that the inaction effect found in real‐life regrets may be due, in part at least, to the self‐enhancement goals of HSE individuals.
