Structural models of psychopathology provide dimensional alternatives to traditional categorical classification systems. Competing models, such as the bifactor and correlated factors are typically compared via statistical indices assess how well each model fits same data. However, simulation studies have found evidence for probifactor fit index bias in several psychological research domains. The present study sought extend this psychopathology, wherein has received much attention, but its...
The present study compared the primary models used in research on structure of psychopathology (i.e., correlated factor, higher-order, and bifactor models) terms structural validity (model fit factor reliability), longitudinal measurement invariance, concurrent prospective predictive relation to important outcomes, consistency individuals' score profiles. Two simpler operationalizations a general were also examined-a single-factor model count diagnoses. Models estimated based structured...
The general factor of psychopathology, or p factor, has received increasing attention over the last half decade, but questions remain about how to best conceptualize it1, 2. Here, we use data from a large-scale survey (National Epidemiologic Survey on Alcohol and Related Conditions, NESARC), conducted in nationally representative US sample, demonstrate that, statistically, is nearly identical sum diagnoses it estimated upon. same holds for specific factors such as internalizing...
Confirmatory factor analysis (CFA) and its bifactor models are popular in empirical investigations of the structure psychological constructs. CFA offers straightforward hypothesis testing but has notable pitfalls, such as imposition strict assumptions (i.e., simple structure) that obscure unmodeled complexity. Due to limitations CFAs, they have yielded anomalous results across samples studies suggest model misspecification (e.g., evaporating specific factors unexpected loadings). We propose...
Historically, researchers have proposed higher-order factors to explicate the structure of psychopathology, including Externalizing, Internalizing, Fear, Distress, Thought Disorder, and a general factor. Despite extensive research in this domain, underlying psychopathology remains unresolved. Here, we examine several issues adjudicating among structural models psychopathology. Using simulations analyses extant literature, contrast model-based reliability alternative highlight shortcomings...
As evidenced by our exchange with Bader and Moshagen (2022), the degree to which model fit indices can should be used for purpose of selection remains a contentious topic.Here, we make three core points.First, discuss common misconception about statistics' abilities identify "best model," arguing that mechanical application contributes faulty inferences in field quantitative psychopathology.We illustrate consequences this practice through examples literature.Second, highlight...
Abstract Combat deployments are stressful life events that confer risk for posttraumatic stress disorder (PTSD) in veterans. Typically, PTSD is conceptualized as being caused by traumatic experiences, leading research to focus predominantly on while excluding other contributors, such personality features. Narcissism may contribute the deleterious effects of trauma exposure because vulnerabilities sense self, demonstrated narcissism and development maintenance civilians. However, strength...
The categorical borderline personality disorder (BPD) diagnosis identifies people who struggle to manage negative emotions. As the field transitions dimensional (PD) models, it is important know whether alternative diagnostic constructs capture emotion regulation difficulties same degree. If not, may make sense modify models or else retain BPD syndrome preserve its incremental utility for clinical description, treatment planning, and prognosis. In three adult samples (total N = 1,197), we...
Objective: Posttraumatic stress disorder (PTSD) is defined by the assumption that qualifying traumatic events lead to a syndrome distinct from other internalizing disorders, while stressful life play prominent role in etiologic theories of major depressive (MDD). We examined whether environmental etiology PTSD and MDD are evaluating relative contributions both conditions. Harmful alcohol use physical limitations served as noninternalizing comparators expected show weaker associations with...
ABSTRACT Introduction Given the high frequency and persistence of suicidal thoughts behaviors among individuals with borderline personality disorder (BPD), characterizing mitigating factors risk is critical. Suicide‐related coping (SRC; knowledge confidence in using internal strategies external supports to manage urges) beneficial for suicide management. However, SRC has not been characterized longitudinally BPD. Methods A clinical sample 98 high‐risk veterans (83% male; 21–73 years old [ M...
This study examined the utility of Suicide Probability Scale (SPS) by comparing results obtained with a sample 217 normal adolescents (M = 16.2 years) to findings in Cull and Gill's (1988) standardization effort. The present scored significantly higher than normative SPS item, subscale, total scores. In addition, generally failed discriminate between present, adolescent inpatient psychiatric sample. Moreover, item-subscale correlations for often differed from those reported Gill, factor...
Only 15% of women meet physical activity guidelines during and after pregnancy despite the well-established positive impacts on both mother neonate. There is a clear lack guidance this topic, mobile health interventions are promising direction for future to facilitate necessary increase in postpartum. The purpose study was objectively assess quality perceived impact existing free apps that designed cover pregnancy. Mobile Application Rating Scale (MARS) used by two independent reviewers...
The p-factor is relatively novel construct that thought to explain and maybe even cause variation in all forms of psychopathology. Since its “discovery” 2012, hundreds studies have been dedicated the extraction validation statistical instantiations p-factor, called general factors In this Perspective, we outline 5 major challenges literature, namely it has: (1) mistakenly equated good model fit with validity; (2) sought corroborate weak theories through underspecified efforts; (3) produced...
