RESUMEN

Risky sexual behaviors (RSBs) incur large societal and personal costs. Despite widespread prevention efforts, RSBs and associated consequences (e.g., sexually transmitted infections) continue to rise. A proliferation of research has emerged on situational (e.g., alcohol use) and individual difference (e.g., impulsivity) factors to explain this rise, but these approaches assume an unrealistically static mechanism underlying RSB. Because this prior research has resulted in few compelling effects, we sought to innovate by examining the interaction of situation and individual differences in explaining RSBs. A large sample (N = 105) completed baseline reports of psychopathology and 30 daily diary reports of RSBs and associated contexts. These data were submitted to multilevel models including cross-level interactions to test a person-by-situation conceptualization of RSBs. Results suggested that RSBs are most strongly predicted from interactions of person- and situation-level factors in both protective and facilitative directions. These interactions outnumbered main effects and commonly included partner commitment as a central mechanism. These results point to theoretical and clinical gaps in preventing RSB and urge a departure from prior ways of conceptualizing sexual risk as a static outcome.

RESUMEN

OBJECTIVE: Social anhedonia is associated with disinterest in social interactions and poor relationship functioning, yet little is known about the specific mechanisms underlying associations between social anhedonia and romantic relationship behaviors and satisfaction. We examined the links between social anhedonia, perceptions of conflict communication patterns, and marital satisfaction. METHOD: The current research examined the role of social anhedonia on marital quality and functioning longitudinally across a year in a sample of 100 newlywed couples using an actor-partner interdependence framework. RESULTS: Social anhedonia was negatively associated with own and partner's marital satisfaction. It was also negatively associated with constructive communication and positively associated with destructive communication. Furthermore, cross-sectional mediation analyses showed that communication patterns mediated the social anhedonia-satisfaction link. CONCLUSIONS: Taken together, these findings suggest that social anhedonia is likely to lead to lower marital satisfaction, partly through its effect on communication between partners.

RESUMEN

OBJECTIVE: The aim of this work was to better understand the role of personality as it relates to psychopathology, with satisfaction as a mediating variable. BACKGROUND: Personality is an important determinant of many life outcomes including relationship satisfaction and psychopathology. Previous work has demonstrated that broad domains of normal personality have low-to-moderate associations with various forms of psychopathology. Research has primarily focused on mechanisms that might explain how common personality traits put one at risk for common forms of psychopathology; this work builds upon existing work in examining relationship satisfaction as one possible mechanism. No study to date has examined whether relationship satisfaction mediates the connection between personality and psychopathology. METHOD: We utilized multilevel modeling in a longitudinal sample of 100 newlywed couples to test the hypothesis that major domains of personality (positive temperament, negative temperament, disinhibition) have a significant effect on relationship satisfaction which, in turn, is significantly associated with internalizing and externalizing forms of psychopathology. RESULTS: We found no evidence for the mediating role of relationship satisfaction; however, in exploratory analyses, we did find evidence for both between-person and within-person effects of personality on psychopathology. CONCLUSIONS: This study confirms the role of personality as an important factor in consideration of dyadic processes, though not entirely deterministic for downstream functioning. Thus, separate factors in addition to personality may be worth examining in consideration of how low relationship satisfaction may be associated with psychopathology.

RESUMEN

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.

RESUMEN

We advocate for an integrative long-term perspective on time, noting that culture changes on timescales amenable to behavioral genetic study with appropriate design and modeling extensions. We note the need for replications of behavioral genetic studies to examine model invariance across long-term timescales, which would afford examination of specified as well as unspecified cultural moderators of behavioral genetic effects.

RESUMEN

Committed, long-term romantic relationships are ubiquitous among modern society. They are one of the most important contexts for the development, maintenance, and treatment of psychopathology. In this review, I first place psychopathology within the most commonly cited theoretical model of marital satisfaction and stability and then discuss how relationship satisfaction is conceptualized and assessed in this literature. In the second half of the review, I describe the theories regarding how romantic relationships may be connected to psychopathology. Relationship distress is easily incorporated into a diathesis-stress model as an important trigger for psychopathology. Next, I review cross-sectional research, longitudinal research, and treatment efficacy research linking relationship quality and psychopathology. I provide evidence for the robustness of these effects and areas where research must expand. I finish with a summary section that synthesizes what is known about the mechanisms linking relationship distress and psychopathology.

RESUMEN

Research suggests that men and women differ on mean levels of Dark Triad personality constructs such as Machiavellianism, but few studies have investigated whether or not these differences are due to actual latent trait differences or bias in measurement. Further, recent research suggests important challenges associated with existing measures of MACH in terms of overlap with psychopathy and matching expert descriptions. The present study took a recently developed measure of Machiavellianism (the Five Factor Machiavellianism Inventory; FFMI), based on the five-factor model, and examined its invariance across gender. Strong (or scalar) factorial invariance was established, indicating that latent factor means can be compared between men and women using this measure. Mean-level differences showed that men had higher levels of latent factors related to antagonism and social dominance. In terms of total score, men reported significantly higher mean levels of Machiavellianism. The findings of the present study lend support to the notion that mean level differences in Machiavellianism across gender are not artifacts of measurement bias.

RESUMEN

Shortcomings of approaches to classifying psychopathology based on expert consensus have given rise to contemporary efforts to classify psychopathology quantitatively. In this paper, we review progress in achieving a quantitative and empirical classification of psychopathology. A substantial empirical literature indicates that psychopathology is generally more dimensional than categorical. When the discreteness versus continuity of psychopathology is treated as a research question, as opposed to being decided as a matter of tradition, the evidence clearly supports the hypothesis of continuity. In addition, a related body of literature shows how psychopathology dimensions can be arranged in a hierarchy, ranging from very broad "spectrum level" dimensions, to specific and narrow clusters of symptoms. In this way, a quantitative approach solves the "problem of comorbidity" by explicitly modeling patterns of co-occurrence among signs and symptoms within a detailed and variegated hierarchy of dimensional concepts with direct clinical utility. Indeed, extensive evidence pertaining to the dimensional and hierarchical structure of psychopathology has led to the formation of the Hierarchical Taxonomy of Psychopathology (HiTOP) Consortium. This is a group of 70 investigators working together to study empirical classification of psychopathology. In this paper, we describe the aims and current foci of the HiTOP Consortium. These aims pertain to continued research on the empirical organization of psychopathology; the connection between personality and psychopathology; the utility of empirically based psychopathology constructs in both research and the clinic; and the development of novel and comprehensive models and corresponding assessment instruments for psychopathology constructs derived from an empirical approach.

RESUMEN

OBJECTIVE: The Big Five Model (BFM) of personality domains is significantly related to romantic relationship outcomes, particularly marital satisfaction. Few studies to date, however, have examined the BFM domains and relationship outcomes longitudinally. METHOD: We used latent growth curve modeling to estimate the initial levels (intercept) and the rate of change (slope) in the BFM domains and marital satisfaction and determine if change in one construct was associated with change in the other. All available data were retained from participants who remained married to the same individual, as well as early waves for participants who divorced or were widowed, in the Midlife in the United States study (N = 1,965). We expected negative associations between (a) intercepts of Neuroticism and relationship satisfaction and (b) the intercept/slope of Neuroticism with change in marital satisfaction. The other BFM domains were expected to have positive effects on change in satisfaction. RESULTS: The results suggested that change over time in Neuroticism and Conscientiousness is detrimental to satisfaction, while initial levels of Conscientiousness may predict declining marital satisfaction. CONCLUSIONS: Changes in Neuroticism accompany parallel changes in relationship satisfaction in a large sample of married U.S. adults, suggesting an ongoing bidirectional influence between these constructs in enduring marriages.

RESUMEN

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.

RESUMEN

Until now, data have not been available to elucidate the genetic and environmental sources of comorbidity between all 10 DSM-IV personality disorders (PDs) and cocaine use. Our aim was to determine which PD traits are linked phenotypically and genetically to cocaine use. Cross-sectional data were obtained in a face-to-face interview between 1999 and 2004. Subjects were 1,419 twins (µage = 28.2 years, range = 19-36) from the Norwegian Institute of Public Health Twin Panel, with complete lifetime cocaine use and criteria for all 10 DSM-IV PDs. Stepwise multiple and Least Absolute Shrinkage and Selection Operator (LASSO) regressions were used to identify PDs related to cocaine use. Twin models were fitted to estimate genetic and environmental associations between the PD traits and cocaine use. In the multiple regression, antisocial (OR = 4.24, 95% CI [2.66, 6.86]) and borderline (OR = 2.19, 95% CI [1.35, 3.57]) PD traits were significant predictors of cocaine use. In the LASSO regression, antisocial, borderline, and histrionic were significant predictors of cocaine use. Antisocial and borderline PD traits each explained 72% and 25% of the total genetic risks in cocaine use, respectively. Genetic risks in histrionic PD were not significantly related to cocaine use. Importantly, after removing criteria referencing substance use, antisocial PD explained 65% of the total genetic variance in cocaine use, whereas borderline explained only 4%. Among PD traits, antisocial is the strongest correlate of cocaine use, for which the association is driven largely by common genetic risks.

RESUMEN

Previous research has established that parental marital discord is associated with higher levels of offspring externalizing behaviors, but it is unclear how parental relationship functioning is associated with the genetic and environmental variance on a factor of externalizing problems. Thus, the current study assessed how parental marital discord moderates genetic and environmental variance on offspring externalizing problems at two different ages: childhood and late adolescence. That is, the magnitude of genetic and environmental influences on offspring externalizing at ages 11 and 17 was examined as a function of parental marital discord. Consistent with a diathesis-stress model of psychopathology, it was hypothesized that with increasing marital discord, genetic influences on externalizing would be more pronounced. Rather, results indicated that for the 11-year-old sample, nonshared environmental influences were greater when parental marital discord was low, and comparatively, shared environmental influences contributed more to the variance in externalizing problems when parental marital discord was high. No moderation was found for the 17-year-old cohort. In contrast to studies that do not find an effect of the shared environment, these results provide evidence that the common rearing environment has an impact on externalizing problems in preadolescent children.

RESUMEN

For more than a decade, biometric moderation models have been used to examine whether genetic and environmental influences on individual differences might vary within the population. These quantitative Gene × Environment interaction models have the potential to elucidate not only when genetic and environmental influences on a phenotype might differ, but also why, as they provide an empirical test of several theoretical paradigms that serve as useful heuristics to explain etiology-diathesis-stress, bioecological, differential susceptibility, and social control. In the current article, we review how these developmental theories align with different patterns of findings from statistical models of gene-environment interplay. We then describe the extant empirical evidence, using work by our own research group and others, to lay out genetically informative plausible accounts of how phenotypes related to social inequality-physical health and cognition-might relate to these theoretical models.

RESUMEN

Grounded in a theoretical model specific to adoptive parents, we examined the relationship between parental expectations and depressive symptoms across time. Assessments of 129 adoptive parents of 64 children were performed at three time points before and after placement of an adopted child with the family: 4-6 weeks pre-placement and 4-6 weeks and 5-6 months post-placement. Expectations were assessed in four dimensions: expectations of self as parents, of the child, of family and friends, and of society. Depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression scale. Associations between parental expectations and depressive symptoms were analyzed, and longitudinal multilevel modeling was conducted to explore influences on expectations over time. Parental expectations changed from pre- to post-placement. With the exception of expectations of self as parent, adoptive parents' pre-adoption expectations were affirmed in the post-adoption time periods. In each expectation dimension, higher affirmation of expectations was correlated with decreased depressive symptoms before and after placement of a child. While parental expectations are not unique to adoptive parents, the essence and characteristics of certain expectations are unique to these parents. When working with adoptive parents, nurses who care for families should assess expectations both pre- and post-placement with awareness of their relationship to depressive symptoms.

RESUMEN

As adoptive parents create a new family, they face myriad changes both pre-and post-placement of their child. The aim of this study was to describe parent perceptions and depressive symptoms during this transition via reports collected with an online survey. Using content analysis, we analyzed a total of 110 responses from 64 parents at three time points: 4-6weeks pre-placement, and 4-6weeks and 5-6months post-placement. Five main themes were revealed: Transition from uncertainty to a new normal; unique experiences related to adoption; rest/fatigue: out of balance; life stressors; and faith/spirituality. Two subthemes were also identified: previous losses (pre-placement) and joy and love (post-placement). During the transition from pre-to post-placement, adoptive parents experience a unique passage, with both challenges and strengths exclusive to this group of parents. While acknowledging the commonalities of some parenting experiences, healthcare and adoption professionals should recognize the unique dynamics that adoption brings to families.

RESUMEN

Many studies have found that education is associated with better health, but the causal basis of this association is unclear. The current study used a co-twin control design to examine if differences in years of education within twin pairs predict allostatic load. The strength of this design is that it controls for genetic and other familial confounds shared between twins. The sample consisted of 381 twins (with 292 twins from 146 complete pairs; mean age=57; 61% female) who participated in the biomarker project of the Midlife Development in the United States (MIDUS) study. Individual-level analyses showed a significant, negative association between years of education and allostatic load, but this association was explained entirely by familial influences shared between twins. The results of this study suggest that schooling does not itself protect against allostatic load.

RESUMEN

The heritability of major normative domains of personality is well-established, with approximately half the proportion of variance attributed to genetic differences. In the current study, we examine the possibility of gene × environment interaction (G×E) for adult personality using the environmental context of intimate romantic relationship functioning. Personality and relationship satisfaction are significantly correlated phenotypically, but to date no research has examined how the genetic and environmental components of variance for personality differ as a function of romantic relationship satisfaction. Given the importance of personality for myriad outcomes from work productivity to psychopathology, it is vital to identify variables present in adulthood that may affect the etiology of personality. In the current study, quantitative models of G×E were used to determine whether the genetic and environmental influences on personality differ as a function of relationship satisfaction. We drew from a sample of now-adult twins followed longitudinally from adolescence through age 29. All participants completed the Multidimensional Personality Questionnaire (MPQ) and an abbreviated version of the Dyadic Adjustment Scale. Biometric moderation was found for eight of the eleven MPQ scales examined: well-being, social potency, negative emotionality, alienation, aggression, constraint, traditionalism, and absorption. The pattern of findings differed, suggesting that the ways in which relationship quality moderates the etiology of personality may depend on the personality trait.

RESUMEN

Researchers have long theorized that genetic influence on mental health may differ as a function of environmental risk factors. One likely moderator of genetic and environmental influences on psychopathological symptoms is parenting behavior, as phenotypic research shows that negative aspects of parent-child relationships are associated with greater likelihood of mental illness in adulthood. The current study examined whether levels of reported parental discipline and affection experienced in childhood act as a trigger, or buffer, for adult mental health problems. Results from a nationwide twin sample suggest level of father's discipline and affection, as reported by now-adult twins, moderated genetic and environmental influences on internalizing symptoms in adulthood, such that heritability was greatest at the highest levels of discipline and affection. Father's affection also moderated the etiological influences on alcohol use problems, with greater heritability at the lowest levels of affection. No moderating effect was found for mothers. Findings suggest relationships with fathers in childhood can have long-lasting effects on the etiological influences on adult mental health outcomes.

RESUMEN

BACKGROUND: Much is unknown about the relationship between socioeconomic status (SES) and alcohol use, including the means by which SES may influence risk for alcohol use. METHODS: Using a sample of 672 twin pairs (aged 25 to 74) derived from the MacArthur Foundation Survey of Midlife Development in the United States, this study examined whether SES, measured by household income and educational attainment, moderates genetic and environmental influences on 3 indices of alcohol use: amount used, frequency of use, and problem use. RESULTS: We found significant moderation for amount of alcohol used. Specifically, genetic effects were greater in low-SES conditions, shared environmental effects (i.e., environmental effects that enhance the similarity of twins from the same families) tended to increase in high-SES conditions, and nonshared environmental effects (i.e., environmental effects that distinguish twins) tended to decrease with SES. This pattern of results was found for both income and education, and it largely replicated at a second wave of assessment spaced 9 years after the first. There was virtually no evidence of moderation for either frequency of alcohol use or alcohol problems. CONCLUSIONS: Our findings indicate that genetic and environmental influences on drinking amount vary as a function of the broader SES context, whereas the etiologies of other drinking phenomena are less affected by this context. Efforts to find the causes underlying the amount of alcohol used are likely to be more successful if such contextual information is taken into account.

RESUMEN

Past research demonstrates a phenotypic relationship between childhood maltreatment and adult health problems. Explanations of this association usually point to either: (a) a direct causal link, whereby exposure to early stress disrupts biological functioning during sensitive periods of development; or (b) an indirect effect operating through socioeconomic attainment, poor health behaviors, or some other pathway leading from childhood to adulthood. The current study examined whether the association between childhood maltreatment and adult health reflects genetic or environmental mediation. Using a large sample of adult American twins, we separately estimated univariate biometric models of child maltreatment and adult physical health, followed by a bivariate biometric model to estimate genetic and environmental correlations between the two variables. We found that a summary count of chronic health conditions shared non-trivial genetic overlap with childhood maltreatment. Our results have implications for understanding the relationship between maltreatment and health as one of active interplay rather than a simple cause and effect model that views maltreatment as an exogenous shock.
