Temporal dynamics of emotional processing: Parsing trial-wise variance of the late positive potential using Generalizability Theory.

The reliability of individual trial event-related potential (ERP) components extracted from electroencephalogram has been consistently questioned since ERP research began. This ambivalence is based on misunderstood assumptions stemming from Cronbach and Classical Test Theory. Contemporary methods allow for the reliability of individual ERP trials to be estimated and for analyses of these trial-level ERP components to be meaningfully parsed. We illustrate the use of Generalizability Theory procedures in estimating the reliability of trial-level ERPs using the late positive potential (LPP), a neural measure of motivated attention toward emotionally evocative stimuli. Individuals (N = 88) completed a passive viewing task while continuous EEG was recorded. Variability in trial-level LPP responses was decomposed into facets corresponding to individual differences, chronological trial within block, stimulus type, their two-way interactions, and specific stimuli. We estimated various reliability coefficients and found that both overall and category-specific person-level LPP estimates have good-to-excellent reliability, while the reliability of within-person differences (i.e., change) between arousal categories was fair for the early LPP. These results were generally consistent across time windows, but were highest early in the LPP time course. We argue that investigating reliability using trial-level data allows researchers to pursue hypotheses focused on neurophysiological dynamics that unfold over the course of an experiment and not risk false inferences (i.e., ecological fallacy) when using person-level aggregates to deduce such processes. Moreover, such analyses provide information that allows researchers to optimize their protocols by potentially reducing the number of individual trials, burden on participants, and cost, while retaining sufficient reliability.

The distinction between symptoms and traits in the Hierarchical Taxonomy of Psychopathology (HiTOP).

The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirically and quantitatively derived dimensional classification system designed to describe the features of psychopathology and, ultimately, to replace categorical nosologies. Among the constructs that HiTOP organizes are "symptom components" and "maladaptive traits," but past HiTOP publications have not fully explicated the distinction between symptoms and traits. We propose working definitions of symptoms and traits and explore challenges, exceptions, and remaining questions. Specifically, we propose that the only systematic difference between symptoms and traits in HiTOP is one of time frame. Maladaptive traits are dispositional constructs that describe persistent tendencies to manifest features of psychopathology, whereas symptoms are features of psychopathology as they are manifest during any specific time period (from moments to days to months). This has the consequence that almost every HiTOP dimension, at any level of the hierarchy, can be assessed as either a trait or a symptom dimension, by adjusting the framing of the assessment. We discuss the implications of these definitions for causal models of the relations between symptoms and traits and for distinctions between psychopathology, normal personality variation, and dysfunction.

Criterion A of the AMPD in HiTOP.

The categorical model of personality disorder classification in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]; American Psychiatric Association, 2013 ) is highly and fundamentally problematic. Proposed for DSM-5 and provided within Section III (for Emerging Measures and Models) was the Alternative Model of Personality Disorder (AMPD) classification, consisting of Criterion A (self-interpersonal deficits) and Criterion B (maladaptive personality traits). A proposed alternative to the DSM-5 more generally is an empirically based dimensional organization of psychopathology identified as the Hierarchical Taxonomy of Psychopathology (HiTOP; Kotov et al., 2017 ). HiTOP currently includes, at the highest level, a general factor of psychopathology. Further down are the five domains of detachment, antagonistic externalizing, disinhibited externalizing, thought disorder, and internalizing (along with a provisional sixth somatoform dimension) that align with Criterion B. The purpose of this article is to discuss the potential inclusion and placement of the self-interpersonal deficits of the DSM-5 Section III Criterion A within HiTOP.

Momentary assessment of interpersonal process in psychotherapy.

To demonstrate how a novel computer joystick coding method can illuminate the study of interpersonal processes in psychotherapy sessions, we applied it to Shostrom's (1966) well-known films in which a client, Gloria, had sessions with 3 prominent psychotherapists. The joystick method, which records interpersonal behavior as nearly continuous flows on the plane defined by the interpersonal dimensions of control and affiliation, provides an excellent sampling of variability in each person's interpersonal behavior across the session. More important, it yields extensive information about the temporal dynamics that interrelate clients' and therapists' behaviors. Gloria's 3 psychotherapy sessions were characterized using time-series statistical indices and graphical representations. Results demonstrated that patterns of within-person variability tended to be markedly asymmetric, with a predominant, set-point-like interpersonal style from which deviations mostly occurred in just 1 direction (e.g., occasional submissive departures from a modal dominant style). In addition, across each session, the therapist and client showed strongly cyclical variations in both control and affiliation, and these oscillations were entrained to different extents depending on the therapist. We interpreted different patterns of moment-to-moment complementarity of interpersonal behavior in terms of different therapeutic goals, such as fostering a positive alliance versus disconfirming the client's interpersonal expectations. We also showed how this method can be used to provide a more detailed analysis of specific shorter segments from each of the sessions. Finally, we compared our approach to alternative techniques, such as act-to-act lagged relations and dynamic systems and pointed to a variety of possible research and training applications.

Evocative gene-environment correlation in the mother-child relationship: a twin study of interpersonal processes.

The behavior genetic literature suggests that genetically influenced characteristics of the child elicit specific behaviors from the parent. However, little is known about the processes by which genetically influenced child characteristics evoke parental responses. Interpersonal theory provides a useful framework for identifying reciprocal behavioral processes between children and mothers. The theory posits that, at any given moment, interpersonal behavior varies along the orthogonal dimensions of warmth and control and that the interpersonal behavior of one individual tends to elicit corresponding or contrasting behavior from the other (i.e., warmth elicits warmth, whereas control elicits submission). The current study thus examined these dimensions of interpersonal behavior as they relate to the parent-child relationship in 546 twin families. A computer joystick was used to rate videos of mother-child interactions in real time, yielding information on mother and child levels of warmth and control throughout the interaction. Analyses indicated that maternal control, but not maternal warmth, was influenced by evocative gene-environment correlational processes, such that genetic influences on maternal control and child control were largely overlapping. Moreover, these common genetic influences were present both cross-sectionally and over the course of the interaction. Such findings not only confirm the presence of evocative gene-environment correlational processes in the mother-child relationship but also illuminate at least one of the specific interpersonal behaviors that underlie this evocative process.

Heterogeneity of interpersonal problems among depressed young adults: associations with substance abuse and pathological personality traits.

This study extended previous theory and research on interpersonal heterogeneity in depression by identifying groups of depressed young adults who differ in their type and degree of interpersonal problems, and by examining patterns of pathological personality traits and alcohol abuse among these groups. We examined the interpersonal problems, personality traits, and alcohol-related problems of 172 college students with at least moderate levels of self-reported depression on the Patient Health Questionnaire (Spitzer, Kroenke, & Williams, 1999). Scores from the Inventory of Interpersonal Problems-Short Circumplex (Soldz, Budman, Demby, & Merry, 1995) were subjected to latent profile analysis, which classified individuals into 5 distinct groups defined by the types of interpersonal problems they experience (dominant, warm, submissive, cold, and undifferentiated). As hypothesized, groups did not differ in depression severity, but did show predicted patterns of differences on normative and maladaptive personality traits, as well as alcohol-related problems. The presence of clinically meaningful interpersonal heterogeneity in depression could have important implications for designing more individualized treatments and prevention efforts for depression that target diverse associated interpersonal problems.

Psychometric properties and norms for the Personality Assessment Inventory in egg donors and gestational carriers.

Although psychological evaluations are an integral element of screening for third-party reproduction and the Personality Assessment Inventory (PAI) is commonly used for these evaluations, little is known about the psychometric properties or normative scores on the PAI among egg donors and carriers. We evaluated the PAI among 1,044 egg donors and gestational carriers from various fertility clinics across the United States. PAI scales were generally internally consistent in this population, although range restriction appeared to attenuate reliability on several scales. The PAI profiles of egg donors and carriers had elevated positive impression management and suppressed clinical scale scores relative to the community standardization sample, as would be expected given the contingencies of this assessment context. Scores were similar across egg donors and carriers and were similar whether the carrier or donor was known or not known to the prospective parents. Sample-specific norms are provided for the use of the PAI in this setting.

The validity of the Personality Diagnostic Questionnaire-4 Narcissistic Personality Disorder scale for assessing pathological grandiosity.

Although controversy surrounds the definition and measurement of narcissism, the claim that pathological grandiosity is central to the construct generates little disagreement. Yet representations of pathological grandiosity vary across measures of narcissism, leading to conceptual confusion in the literature. The validity of a DSM-based measure of pathological narcissism, the Personality Diagnostic Questionnaire-4 Narcissistic Personality Disorder scale (PDQ-4 NPD), was evaluated in 1 clinical and 3 nonclinical samples (total N=2,391) for its ability to measure pathological grandiosity. Findings were generally supportive: average scores were higher in the clinical than nonclinical samples and the PDQ-4 NPD scale correlated most strongly with (a) other measures of NPD; (b) other DSM Cluster B personality disorders; (c) traits involving antagonism, hostility, and assertiveness; and (d) interpersonal distress and disaffiliative dominance. However, the low internal consistency of the PDQ-4 NPD scale and unexpected associations with Cluster A and obsessive-compulsive features point to potential psychometric weaknesses with this instrument. These findings are useful for evaluating the PDQ-4 NPD scale and for informing ongoing debates regarding how to define and assess pathological narcissism.

Differentiations in Interpersonal Functioning Across Narcissism Dimensions.

Narcissism can be conceived hierarchically at three levels: as a global construct (Level 1), as two dimensions (Level 2; grandiosity and vulnerability), and as a trifurcated model with three underlying dimensions: interpersonal antagonism, narcissistic neuroticism, and agentic extraversion (Level 3). The aim of the study was to examine how narcissism dimensions across the three levels differ in their associations with various forms of interpersonal functioning. The authors assessed multiple domains of interpersonal functioning using data collected from 447 MTurk workers, 606 students, and 365 informants. Each narcissism dimension showed unique interpersonal profiles. The profile of interpersonal antagonism largely resembles grandiose and total narcissism in its interpersonal characteristics, narcissistic neuroticism largely resembles vulnerable narcissism, and agentic extraversion does not differ much from the traditional conceptualization of extraversion in its interpersonal qualities (e.g., high communion). Future studies may benefit from studying narcissism and how it relates to other psychological constructs using the trifurcated model.

The differential effects of child abuse and posttraumatic stress disorder on schizotypal personality disorder.

OBJECTIVE: Previous findings suggest a relation between trauma exposure and risk for schizotypal personality disorder (SPD). However, the reasons for this relationship are not well understood. Some research suggests that exposure to trauma, particularly early trauma and child abuse, as well as posttraumatic stress disorder (PTSD) may play a role. METHODS: We examined subjects (n = 541) recruited from the primary care clinics of an urban public hospital as part of an National Institute of Mental Health-funded study of trauma-related risk and resilience. We evaluated childhood abuse with the Childhood Trauma Questionnaire and the Early Trauma Inventory and SPD with the Schedule for Nonadaptive and Adaptive Personality. We assessed for lifetime PTSD using the Clinician-Administered PTSD Scale. RESULTS: We found that of the 3 forms of abuse analyzed (emotional, physical, and sexual), only emotional abuse significantly predicted SPD (P < .001, R = 0.28) when all 3 abuse types were simultaneously entered into a regression model. Lifetime PTSD symptoms also significantly predicted SPD (P < .001, R = 0.26). Posttraumatic stress disorder was specifically predictive of 4 of the 8 SPD symptoms (P ≤ .001): excessive social anxiety, a lack of close friends or confidants, unusual perceptual experiences, and eccentric behavior or appearance. Using a Sobel test, we also found a partial mediation effect of PTSD on the relation between emotional abuse and SPD (z = 3.45, P < .001). CONCLUSIONS: These findings point to the important influence of emotional abuse on SPD and suggest that PTSD symptoms may provide a link between damaging childhood experiences and SPD symptoms in traumatized adults.

An Interpersonal Approach to Social Preference: Examining Patterns and Influences of Liking and Being Bothered by Interpersonal Behaviors of Others.

Personality disorders are rooted in maladaptive interpersonal behaviors. Previously, researchers have assessed interpersonal behaviors using self-ratings of one's own behaviors and third-person ratings of dyadic interactions. Few studies have examined individuals' perceptions of others' interpersonal behaviors. Using a sample of 470 undergraduate students, the authors examined patterns of interpersonal perception as well as influences of these patterns on psychological functioning. Findings showed that people tend to like interpersonal behaviors that are similar to their own and become bothered by behaviors that are the opposite of their own. Such a pattern is particularly characteristic on the warmth dimension and is consistent across different levels of closeness of the relationship. The authors also found small but significant effects of interpersonal perception on personality and general psychological functioning, above and beyond effects of individuals' own interpersonal traits. Such findings highlight the importance of including perceptions of others in investigating interpersonal dynamics when understanding personality disorders.

Mapping Big Five Personality Traits Within and Across Domains of Interpersonal Functioning.

The Big Five and the interpersonal circumplex are among the most extensively used structural frameworks in personality research. Of the five factors, extraversion and agreeableness are theorized to carry the most interpersonal context, however, all five factors are likely to have important interpersonal implications. In the present study, we evaluated the associations between domains of interpersonal functioning and the Big Five domains and facets using the bootstrapped structural summary method. Results suggested that all Big Five traits showed prototypical and specific interpersonal profiles, with variability observed across lower order facets and domains of interpersonal functioning. Several Big Five traits and facets not overtly related to interpersonal behavior nonetheless showed specific, prototypical associations to interpersonal profiles. Findings suggest that Big Five traits and facets are saturated with interpersonal content and even personality characteristics that are not explicitly interpersonal may still have specific interpersonal implications.

A variance decomposition of the Continuous Assessment of Interpersonal Dynamics.

The Continuous Assessment of Interpersonal Dynamics (CAID) is an observational coding method that enables continuous tracking of warmth and dominance in both members of a dyad as an interaction unfolds. Research using this tool has revealed dynamic patterns relevant to psychopathology and psychotherapy, suggesting considerable potential for clinical assessment and research. However, CAID data are sensitive to a variety of person and situational factors, and the way that these factors combine to influence CAID data is poorly understood. We examined data from 10 raters using CAID to assess moment-to-moment warmth and dominance in opposite-sex married dyads (N = 137 couples) interacting in four distinct situations. Using Generalizability Theory methods, we decomposed sources of variance in CAID data and estimated multiple forms of between- and within-person reliability. Results revealed how spouses' moment-to-moment behaviors varied as a function of person, sex, dyad, rater, situation, and relevant interactions between these factors. Based on these results, we provided guidelines for interpreting CAID data at different levels of aggregation in clinical research and practice.

Using Interpersonal Dimensions of Personality and Personality Pathology to Examine Momentary and Idiographic Patterns of Alliance Rupture.

The Alternative Model of Personality Disorders (AMPD) integrates several theoretical models of personality functioning, including interpersonal theory. The interpersonal circumplex dimensions of warmth and dominance can be conceptualized as traits similar to those in AMPD Criterion B, but interpersonal theory also offers dynamic hypotheses about how these variables that change from moment to moment, which help to operationalize some of the processes alluded to in AMPD Criterion A. In the psychotherapy literature, dynamic interpersonal behaviors are thought to be critical for identifying therapeutic alliance ruptures, yet few studies have examined moment-to-moment interpersonal behaviors that are associated with alliance ruptures at an idiographic level. The current study examined the concurrent and cross-lagged relationships between interpersonal behaviors and alliance ruptures within each session in the famous Gloria films ("Three Approaches to Psychotherapy"). Interpersonal behaviors (warmth and dominance) as well as alliance ruptures (i.e., withdrawal and confrontation) were calculated at half minute intervals for each dyad. We identified distinct interpersonal patterns associated with alliance ruptures for each session: Gloria (patient)'s warmth was positively related with withdrawal ruptures concurrently in the session with Carl Rogers; Gloria's dominance and coldness were related with increased confrontation ruptures in the session with Fritz Perls concurrently, while her coldness was also predicted by confrontation ruptures at previous moments; lastly, both Gloria's dominance and Albert Ellis's submissiveness were positively related with withdrawal ruptures. These interpersonal patterns demonstrated the promise of using AMPD dimensions to conceptualize momentary interpersonal processes related to therapy ruptures, as well as the clinical importance of attuning to repetitive, dyad-specific interpersonal cues of ruptures within each session.

Personality Pathology and Spouses' Moment-to-Moment Interpersonal Behaviors.

We assessed the association of personality pathology with romantic couples' observed interpersonal behaviors. Couples engaged in four discussion tasks, after which observers used the Continuous Assessment of Interpersonal Dynamics method to continuously rate each participant's dominance and warmth over the course of each discussion. Using these ratings, we derived indices of average behaviors and changes in behaviors over the course of discussions. Generally, results indicated that the more personality pathology either spouse reported, the colder husbands were on average, and the colder they became toward their wives over time. However, personality disorder symptoms and overall interpersonal problems were largely unassociated with wives' behaviors. Results also indicated that the more dominance-related problems husbands and wives reported, the more dominantly and coldly they behaved, the more submissive or withdrawn their partners were, and the colder wives became over time; and the more warmth problems wives reported, the more dominantly, they behaved.

Properties of the Continuous Assessment of Interpersonal Dynamics Across Sex, Level of Familiarity, and Interpersonal Conflict.

The Continuous Assessment of Interpersonal Dynamics (CAID) is a method in which trained observers continuously code the dominance and warmth of individuals who interact with one another in dyads. This method has significant promise for assessing dynamic interpersonal processes. The purpose of this study was to examine the impact of individual sex, dyadic familiarity, and situational conflict on patterns of interpersonal warmth, dominance, and complementarity as assessed via CAID. We used six samples with 603 dyads, including two samples of unacquainted mixed-sex undergraduates interacting in a collaborative task, two samples of couples interacting in both collaborative and conflict tasks, and two samples of mothers and children interacting in both collaborative and conflict tasks. Complementarity effects were robust across all samples, and individuals tended to be relatively warm and dominant. Results from multilevel models indicated that women were slightly warmer than men, whereas there were no sex differences in dominance. Unfamiliar dyads and dyads interacting in more collaborative tasks were relatively warmer, more submissive, and more complementary on warmth but less complementary on dominance. These findings speak to the utility of the CAID method for assessing interpersonal dynamics and provide norms for researchers who use the method for different types of samples and applications.

Measurement invariance of the DSM-5 Section III pathological personality trait model across sex.

The dimensional pathological personality trait model proposed in the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5), Section III Criterion B, has shown promising results for its validity and utility in conceptualizing personality pathology. However, as its structural equivalence across sex is yet to be tested, the validity for the model across males and females remains uncertain. In the present article, we examined sex measurement invariance of the DSM-5 trait model in a large undergraduate sample using the Personality Inventory for DSM-5. A series of confirmatory and exploratory factor analyses suggested that, although the exact facet-domain relationships as specified in the DSM-5 were not observed, the facets generally organize into a model with five latent factors similar to those listed in the DSM-5 Section III Criterion B. Further, these five factors were fully measurement invariant across sex at the configural, metric, and scalar levels. Examination of the latent trait mean levels suggests that females tend to have higher scores on latent Negative Affectivity, whereas males tend to have higher scores on latent Antagonism, Detachment, Psychoticism, and Disinhibition. These results indicate that the DSM-5 Section III pathological personality trait model is fully structurally equivalent across sex, a property that is lacking in the traditional categorical model in Section II. This further validates the use of the dimensional DSM-5 trait model for personality disorder assessment and conceptualization in both research and clinical settings.

Periodontal-systemic disease education in United States dental hygiene programs.

The relationship between periodontal disease and systemic disease has gained much attention in recent years in the dental profession and from national health care agencies. Two third-party providers are now modifying their dental reimbursements for patients who have periodontal disease and are pregnant or have cardiovascular disease. However, there are few reports in the dental or dental hygiene literature about how students are taught this information and how it is incorporated into the didactic and clinical aspects of the curriculum. A thirty-item survey and cover letter on these subjects were emailed to the directors of the 286 accredited dental hygiene programs in the United States in 2007. The response rate was 63 percent. According to these responses, the three most emphasized topics regarding oral-systemic disease are diabetes, tobacco use, and cardiovascular disease. Most programs (90 percent) use journal articles for instructional content, and 87 percent use the American Academy of Periodontology website for reference. Only 4 percent have content taught jointly with nursing, medical, or allied health students. The majority of directors (87 percent) indicated they could use more evidence-based educational materials to help teach the concepts to students. Only 9 percent of survey respondents thought that nurses and physicians are knowledgeable about the relationship of oral health to systemic disease. The findings indicate that dental hygiene program directors are confident about the education on oral-systemic content provided to their dental hygiene students, but would like additional evidence-based materials to help their students learn this topic.
