RESUMO

This article examines wording effects when positive and negative worded items are included in psychological assessment. Wordings effects have been analyzed in the literature using statistical approaches based on population homogeneity assumptions (i.e. CFA, SEM), commonly adopting the bifactor model to separate trait variance and wording effects. This article presents an alternative approach by explicitly modeling population heterogeneity through a latent profile model, based on the idea that a subset of individuals exhibits wording effects. This kind of mixture model allows simultaneously to classify respondents, substantively characterize the differences in their response profiles, and report respondents' results in a comparable manner. Using the Rosenberg's self-esteem scale data from the LISS Panel (N = 6,762) in three studies, we identify a subgroup of participants who respond differentially according to item-wording and examine the impact of its responses in the estimation of the RSES measurement model, in terms of global and individual fit, under one-factor and bifactor models.The results of these analyses support the interpretation of wording effects in terms of a theoretically-proposed differential pattern of response to positively and negatively worded items, introducing a valuable tool for examining the artifactual or substantive interpretations of such wording effects.

RESUMO

Home visiting programs are evidence-based interventions that have a myriad outcomes for mothers and newborns. Chile offers these services as part of the Chile Crece Contigo, a nationwide program. However, implementing home visiting programs in community settings is difficult. In this study, we report clinic, provider, and participant engagement with the implementation of advanced home visits (ViDAs) in Chilean primary care clinics. ViDAs include a high number of visits, external supervision, and the use of technology. In this study, qualitative and quantitative data were collected to assess the initial implementation of the home visiting strategy. Qualitative data consisted of individual interviews and focus groups with directors of city health departments, clinic managers, and providers conducting home visits. Quantitative data included clinic, provider, and participant recruitment. City health departments were approached to authorize the participation of primary care clinics in the ViDAs program. Then, clinic directors were invited to approve the implementation of the home visiting program at their health centers. In total, 16 clinics, 42 practitioners, and 185 participants were recruited. A large amount of resources was needed to recruit clinics, providers, and participants. The intervention had low acceptability, low adoption, and a high implementation cost. Initial program implementation experienced several challenges. Identified facilitators and barriers both highlighted the need for community engagement at all levels for the successful implementation of an innovation in Chilean primary care clinics. In addition, this article provides recommendations for practitioners and researchers regarding the conduct of research in community-based settings.

RESUMO

BACKGROUND: The externalizing spectrum contains a range of disinhibition-related conditions, such as conduct disorder, antisocial personality disorder, and substance use disorders. Comorbidity among externalizing disorders is commonly investigated at the syndromal and trait level precluding insight into the relationship of symptoms across externalizing disorders. It is unknown whether comorbidity across externalizing disorders holds constant across highly varied, individual alcohol use disorder (AUD) criteria. AUD criteria range from symptoms reflecting neuroadaptation (e.g., tolerance) to symptoms reflecting behavioral problems (e.g., social problems). The present study aimed to determine the degree to which individual AUD criteria are associated with symptomatology from other externalizing disorders. Characterization of the degree to which AUD criteria reflect neuroadaptation versus behavioral problems can be used to identify symptom profiles, which, in turn, can be used to inform diagnostic and treatment approaches. METHODS: Data from 2 large nationally representative samples were used to examine associations between AUD criteria and externalizing behavior. Psychometric inquiries via multivariate and factor analytic approaches estimated relative associations of externalizing behavior and AUD criteria endorsement, as compared to alcohol consumption. RESULTS: Our results indicate differential relations of externalizing behavior and AUD criteria endorsement. For example, social problems and role interference criteria were most strongly associated with externalizing behavior across analytic approaches, with general and unique associations with externalizing behavior. Additionally, tolerance was most weakly associated with externalizing behavior across approaches. CONCLUSIONS: Results highlight potential etiological heterogeneity among AUD criteria that could guide future diagnostic refinements and aid in the identification of treatment targets.

RESUMO

BACKGROUND: Daily drinking is an important public health concern and informative for evaluating diagnostic classification. In particular, daily binge drinkers might be considered as the prototype of some forms of alcoholism, as this drinking pattern may drive many alcohol use disorder (AUD) symptoms. However, daily drinking potentially captures a wide range of drinkers, including light-moderate daily drinkers who exhibit presumed control over their drinking behavior and might benefit from salutary effects on health. This study examined the heterogeneity of daily drinkers in detail. METHODS: Data from the 2 waves of the National Epidemiologic Survey on Alcohol and Related Conditions were used. Participants who reported drinking "every day" during the last 12 months were classified as daily drinkers. A series of regression and logistic regression analyses were conducted to investigate the association between daily drinking and various outcomes. RESULTS: Daily drinkers were found to vary considerably from each other with respect to diagnostic status, level of consumption, demographic composition, and a range of drinking and health correlates. Further, a substantial number of daily binge drinkers were not diagnosed with AUD under the DSM-IV or DSM-5, although in most groups, the DSM-5 criteria diagnosed a larger percentage of participants. CONCLUSIONS: Daily drinkers represent a highly heterogeneous group, and the correlates of daily drinking depend on the usual quantity of daily drinks and the frequency of alcohol-related problems in a given sample. Moreover, AUD, defined both according to DSM-IV and DSM-5, did not capture more than 68% of daily binge drinkers. Given that daily binge drinking is an extremely high threshold for use, this finding may present a challenge for our current classification system.

RESUMO

BACKGROUND: Alcohol withdrawal (AW) is an important clinical and diagnostic feature of alcohol dependence. AW has been found to predict a worsened course of illness in clinical samples, but in some community studies, AW endorsement rates are strikingly high, suggesting false-positive symptom assignments. Little research has examined the validity of the DSM-5 algorithm for AW, which requires either the presence of at least 2 of 8 subcriteria (i.e., autonomic hyperactivity, tremulousness, insomnia, nausea, hallucinations, psychomotor agitation, anxiety, and grand mal seizures), or, the use of alcohol to avoid or relieve these symptoms. METHODS: We used item and algorithm analyses of data from waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (current drinkers, n = 26,946 at wave 1) to study the validity of DSM-5 AW as operationalized by the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV (AUDADIS-IV). RESULTS: A substantial proportion of individuals given the AW symptom reported only modest to moderate levels of alcohol use and alcohol problems. Alternative AW algorithms were superior to DSM-5 in terms of levels of alcohol use and alcohol problem severity among those with AW, group difference effect sizes, and predictive validity at a 3-year follow-up. The superior alternative algorithms included those that excluded the nausea subcriterion; required withdrawal-related distress or impairment; increased the AW subcriteria threshold from 2 to 3 items; and required tremulousness for AW symptom assignment. CONCLUSIONS: The results indicate that the DSM-5 definition of AW, as assessed by the AUDADIS-IV, has low specificity. This shortcoming can be addressed by making the algorithm for symptom assignment more stringent.

RESUMO

Socio-emotional processing is an essential part of development, and age-related changes in its neural correlates can be observed. The late positive potential (LPP) is a measure of motivated attention that can be used to assess emotional processing; however, changes in the LPP elicited by emotional faces have not been assessed across a wide age range in childhood and young adulthood. We used an emotional face matching task to examine behavior and event-related potentials (ERPs) in 33 youth aged 7-19 years old. Younger children were slower when performing the matching task. The LPP elicited by emotional faces but not control stimuli (geometric shapes) decreased with age; by contrast, an earlier ERP (the P1) decreased with age for both faces and shapes, suggesting increased efficiency of early visual processing. Results indicate age-related attenuation in emotional processing that may stem from greater efficiency and regulatory control when performing a socio-emotional task.

RESUMO

According to Lewisohn's model of depression, decreases in behavioral activation (BA) occurring after facing a vital stressor may increase the risk of depression. Transition to parenthood is a potentially stressful life event that increases the risks of postpartum depression. We aimed to (a) describe the changes in BA and depressive symptomatology between the prepartum period, 1 month, 3 months, and 6 months postpartum and (b) evaluate the bidirectionality of the relationship between intraindividual changes in BA and intraindividual changes in depressive symptoms longitudinally. Chilean pregnant women (N = 503) completed a battery of questionnaires when they were between 32 and 37 weeks of gestation and 1, 3, and 6 months after delivery. A repeated measures analysis of variance showed that BA significantly decreased from prepartum to 1 month postpartum. A random intercept cross-lagged panel model supported the bidirectional inverse relationship between intraindividual changes in BA and intraindividual changes in depressive symptoms. The effect sizes of these associations were large (ßs ranging from -.141 to -.243) according to Orth et al. (2022)'s recommendations for cross-lagged effect benchmarks. This relationship showed robustness when multigroup random intercept cross-lagged panel models were conducted to adjust for several covariates (i.e., marital status, the type of health insurance, type of delivery, primiparous vs. multiparous participants, and pregnancy or delivery complication or newborn health problem). Nonetheless, reporting a previous history of major depression moderated this relationship so that intraindividual decreases in BA more likely led to intraindividual increases in depressive symptoms in people with a history of depression than in people without such a history. We discuss implications for behavioral models of depression. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

Numerous dual-systems models of personality have been posited, which propose that behavior is influenced by two complementary systems. A bottom-up system is characterized by emotion-based drive (e.g., urge for rewarding experience), and a top-down system is characterized by the ability to control those urges. Although evidence suggests that these two systems are distinct and may be important in explaining some behaviors, these constructs are also moderately correlated. Notably, there has been little molecular or behavior genetic research on the genetic distinctness of the two systems central to the dual-systems model. The current study used a national twin sample to investigate the degree to which bottom-up and top-down systems, measured here as personality traits of sensation seeking and lack of planning, respectively, covary through genetic and environmental influences. Whereas the overlap between these systems was primarily comprised of unshared environmental influences (e.g., measurement error and unshared systematic variation) in females, a statistically significant proportion of the overlap was accounted for by genetic factors in men. Further, the genetic factors for these systems were moderately to highly correlated in men (rG = 0.62-0.79). These results provide clear support for a dual-systems model in women; however, these systems appear to share some common genetic influences in men.

RESUMO

OBJECTIVES: Our aim was to determine if the decrease in drug use disorders with age is attributable to changes in persistence, as implied by the notion of maturing out. Also, we examined the association between role transitions and persistence, recurrence, and new onset of drug use disorders. METHODS: We performed secondary analysis of the 2 waves of the National Epidemiologic Survey on Alcohol and Related Conditions data (baseline assessment 2001-2002, follow-up conducted 2004-2005). We conducted logistic regressions and multinomial logistic regression to determine the effect of age on wave 2 diagnosis status, as well as the interaction between age and role transitions. RESULTS: Rates of persistence were stable over the life span, whereas rates of new onset and recurrence decreased with age. Changes in parenthood, marital, and employment status were associated with persistence, new onset, and recurrence. We found an interaction between marital status and age. CONCLUSIONS: Our findings challenge commonly held notions that the age-related decrease in drug use disorders is attributable to an increase in persistence, and that the effects of role transitions are stronger during young, compared with middle and older, adulthood.

RESUMO

The negative impact of ageism on the mental health of older persons has been well studied, but the mechanisms underlying this relationship have not been explored in detail. The present study examines the relationship of ageism with depressive and anxious symptoms in older people, evaluating the indirect effect via loneliness. The analysis was carried out with a sample of 577 older adults living in Chile, using structural equation modeling to assess the direct and indirect effects of the proposed model.The results showed the direct and indirect association of ageism with mental health outcomes. Ageism is positively related to loneliness and, in turn, to increased depressive and anxious symptoms. We discuss how loneliness linked with an ageist context contributes to anxiety and depressive symptomatology in the older population and the need to reduce ageism to favor the mental health of this age group.

RESUMO

The aim is to analyse the relationship between social influence for Internet use and Internet addiction (IA) in older women, considering the use of Internet-based social networks as a mediator. The participants were 480 older women Internet users. Social influence, frequency of use of social networks and IA (including loss of control and emotional dysregulation) were evaluated. Structural Equation Modeling (SEM) was conducted to analyse the proposed model. The use of social networks was a significant mediator in the relationship between social influence for Internet use and the dimension of loss of control of IA. On the contrary, social network use was not a significant mediator. Older women with more social influence reported more frequency of social networking and, in turn, more loss of control in Internet use. Public policy and clinicians should address addictive behaviours about Internet use in older women, preventing the negative consequences.

RESUMO

This article explores the analysis and interpretation of wording effects associated with using direct and reverse items in psychological assessment. Previous research using bifactor models has suggested a substantive nature of this effect. The present study uses mixture modeling to systematically examine an alternative hypothesis and surpass recognized limitations in the bifactor modeling approach. In preliminary supplemental Studies S1 and S2, we examined the presence of participants who exhibited wording effects and evaluated their impact on the dimensionality of Rosenberg's Self-Esteem and the Revised Life Orientation Test, confirming the ubiquity of wording effects in scales containing direct and reverse items. Then, after analyzing the data for both scales (n = 5,953), we found that, despite a significant association between wording factors (Study 1), a low proportion of participants simultaneously exhibited asymmetric responses in both scales (Study 2). Similarly, despite finding both longitudinal invariance and temporal stability of this effect in three waves (n = 3,712, Study 3), a small proportion of participants was identified with asymmetric responses over time (Study 4), reflected in lower transition parameters compared to the other patterns of profiles examined. In both cases, we illustrate how bifactor models capitalize on the responses of individuals who do not even exhibit wording effects, yielding spurious correlations suggesting a substantive nature of the wording effect. These findings support the notion of an ephemeral nature underlying wording effects. The discussion focuses on alternative hypotheses to understand these findings and emphasizes the utility of including reverse items in psychological assessment.

RESUMO

BACKGROUND: Symptoms often play an important role in the scientific inquiry of psychological disorders and have been theorized to play a functional role in the disorders themselves. However, little is known about the course of specific symptoms and individual differences in course. Understanding the course of specific symptoms and factors influencing symptom course can inform psychological theory and future research on course and treatment. METHODS: The current study examined alcohol use disorder (AUD) criteria to explore how etiologically relevant covariates differentially affected the course of individual criteria. The study examined 34,653 participants from Wave 1 (2001-2002) and Wave 2 (2003-2004) of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC), to analyze the extent to which AUD symptom course is predicted by alcohol consumption patterns, family history of alcoholism, the presence of internalizing and externalizing disorders, and race. RESULTS: The course of all AUD criteria was significantly influenced by these predictors, with the magnitude of the influence varying across different criteria and different aspects of the course (i.e., onset, persistence, recurrence). The strength of the relationship is partially related to the theoretical proximity of a given covariate to AUD symptomatology, with heavy drinking being the strongest and family history of AUD being the weakest. The course of all criteria was strongly associated with the prevalence of the criterion in the overall sample. CONCLUSIONS: The course of AUD criteria is heterogeneous, appearing to be influenced by conceptually proximal predictors, the prevalence of the criterion, and perhaps an underlying common factor. Diagnostic accuracy may be improved by including a criterion related to alcohol consumption. Future work should include exploring the interchangeability of criteria and alternative operationalization of them.

RESUMO

BACKGROUND: Early Psychological First Aid (PFA) has been widely recommended for preventing posttraumatic stress disorder (PTSD). However, its lack of empirical evidence of safety and effectiveness has been criticized. OBJECTIVES: To assess the effectiveness of PFA-ABCDE, an original PFA protocol, for preventing PTSD one month after the intervention and decreasing PTSD symptoms at one and six months of follow up. METHODS: We assessed the eligibility of 1,140 adult survivors of recent trauma (≤ 72 hours) consulting five emergency departments in Chile. Two hundred twenty-one were randomized to receive either PFA-ABCDE (active listening, breathing retraining, categorization of needs, referral to ancillary services, and psychoeducation) or only psychoeducation. We used the Composite International Diagnostic Interview (CIDI) to assess PTSD diagnosis. The Posttraumatic Checklist (PCL), the Beck Depression Inventory-II (BDI-II), and a 0-10 points analogue visual scale were used to assess PTSD symptoms, depressive symptoms, and immediate distress relief after the intervention. RESULTS: We found no difference between the experimental and control groups in the frequency of PTSD one month after the intervention (PFA-ABCDE = 23/76 [30.3%], psychoeducation = 18/75 [24.0%], adjusted odds ratio = 1.39, 95% confidence interval = 0.63-3.07, p = .408). Immediately after the intervention, participants who received PFA-ABCDE reported greater distress relief (PFA-ABCDE mean = 9.06, psychoeducation mean = 8.55, Cohen's d = 0.30, p = .038). Fewer PTSD symptoms were reported by those who received PFA-ABCDE one month after the intervention (PFA-ABCDE mean = 36.26, psychoeducation mean = 43.62, Cohen's d = 0.42, p = .033). We found no difference in depressive symptoms at one-month follow up (p = .713) nor in PTSD symptoms six months after the intervention (p = .986). CONCLUSIONS: PFA-ABCDE does not prevent PTSD diagnosis, but it provides immediate distress relief and decreases PTSD symptoms in the short term.


Antecedentes: Los Primeros Auxilios Psicológicos (PAP) han sido recomendados para prevenir el Trastorno de Estrés Postraumático (TEPT) en supervivientes de trauma. A pesar de su popularidad, la escasez de evidencia empírica sobre su seguridad y efectividad ha sido criticada.Objetivos: Evaluar la efectividad de los PAP-ABCDE, un protocolo original de PAP, para prevenir el TEPT al mes de seguimiento y disminuir los síntomas de TEPT luego de uno y seis meses de seguimiento.Métodos: Evaluamos elegibilidad de 1.140 adultos supervivientes de trauma reciente (≤ 72 horas) que consultaron cinco servicios de urgencia en Chile. Doscientos veintiún fueron aleatorizados a recibir PAP-ABCDE (escucha activa, reentrenamiento de la respiración, categorización de necesidades, derivación a redes de apoyo, y psicoeducación) o sólo psicoeducación. Utilizamos la Composite International Diagnostic Interview (CIDI) para evaluar el diagnóstico de TEPT. La Posttraumatic Checklist (PCL), la Beck Depression Inventory-II (BDI-II), y una escala visual análoga de 0-10 puntos fueron utilizadas para evaluar síntomas de TEPT, síntomas depresivos, y alivio inmediato de distrés luego de la intervención.Resultados: No encontramos diferencia entre el grupo experimental y el grupo control en la frecuencia de TEPT un mes después de la intervención (PAP-ABCDE = 23/76 [30,3%], psicoeducación = 18/75 [24,0%], odds ratio ajustado = 1,39, intervalo de confianza 95% = 0,63-3,07, p = ,408). Inmediatamente después de la intervención los participantes que recibieron PAP-ABCDE reportaron un mayor alivio de distrés (media en PAP = 9,06, media en psicoeducación = 8,55, d de Cohen = 0,30, p = ,038). Menos síntomas de TEPT fueron reportados un mes después de la intervención por aquellos que recibieron PAP-ABCDE (media de PAP-ABCDE = 36,26, media de psicoeducación = 43,62, d de Cohen = 0,42, p = ,033). No encontramos diferencias en síntomas depresivos al mes de seguimiento (p = ,713) ni en síntomas de TEPT seis meses después de la intervención (p = ,986).Conclusiones: Los PAP-ABCDE no previenen el diagnóstico de TEPT, pero brindan alivio inmediato del distrés y disminuyen la severidad de los síntomas del TEPT en el corto plazo.

RESUMO

OBJECTIVES: This study aims to evaluate a comprehensive model that includes predictors of use, types of Internet use, and psychological well-being outcomes in the older population. METHODS: The total sample comprised 650 older Internet users. Structural equation modeling was used to estimate the effect of predictors (i.e., effort expectancy, performance expectancy, social influence, and ageism) on types of Internet use (i.e., information seeking, communication, instrumental use, and leisure) and the impact of the type of use on the psychological well-being of older adults (i.e., depressive and anxious symptomatology). In addition, the indirect effect of different types of Internet use was evaluated, that is, they were considered as mediator variables. RESULTS: Effort expectancy, social influence, and ageism predicted different types of Internet use. The relationship between effort expectancy and anxious symptomatology had an indirect effect via information seeking, whereas the relationship between ageism and anxious symptomatology showed an indirect effect via leisure. DISCUSSION: The findings support the importance of differentiating the types of Internet use to understand its impact on psychological well-being. Information seeking is associated with anxious symptomatology and is predicted by effort expectancy. On the contrary, leisure is crucial because of its relationship with anxious symptomatology, and less ageism can promote it. This information is useful for developing effective interventions that promote the well-being of older adults through the Internet, including strategies to cope with some online challenges that could lead to negative consequences, such as information overload.

RESUMO

Dopamine neurotransmission has been consistently associated with individual differences in impulsive choice. Clinical and preclinical evidence suggests that low striatal dopamine D2 signaling predisposes to engage in impulsive behaviors. Although dopamine D2 signaling controls dopamine (DA) extracellular levels, the relationship between striatal dopamine extracellular levels and impulsive choice remains poorly understood. Using quantitative microdialysis, we investigated whether extracellular DA levels in rat dorsolateral striatum (DLS) correlates with preference for an immediate small reward or for a delayed larger reward. Rats were tested in a delay-discounting task and classified as high impulsive (HI) or low impulsive (LI) according to the area under the discounting curve (AUC). No-net flux microdialysis experiments, assessing basal DA release, DA-uptake, and DA extracellular concentration (DA Cext), were carried out in dorsolateral striatum (DLS) of urethane-anesthetized rats. Rats classified as HI showed a higher DA release compared with LI rats. Differences in DLS DA-uptake and DA Cext were non-significant. Importantly, a significant negative correlation was observed between AUC and DA release, indicating that the lower the AUC, the higher the DLS DA release. This finding shows that DA release is augmented in the DLS of rats classified as HI, suggesting that a hyper-activated nigro-striatal pathway contributes to impulsive choice.

RESUMO

OBJECTIVE: Recent studies have examined the extent to which alcohol dependence (AD) criteria prospectively predict the course of AD. Critically, these studies have lacked a developmental perspective. However, the differential performance of criteria by age might indicate overendorsement in younger individuals. The current study examined AD criteria in terms of persistence and prediction of AD course and alcohol use by age in order to identify criteria that are likely to be overly endorsed by younger individuals. METHOD: The current study used longitudinal data from the National Epidemiologic Survey on Alcohol and Related Conditions to depict age differences in rates of new onset, recurrence, and persistence for each AD criterion, thereby showing how these three factors contribute to the overall age-prevalence curve of each criterion. Additionally, we tested age moderation of the predictive association between each criterion at baseline and new onset, recurrence, and persistence of syndromal AD. RESULTS: Some criteria (particularly, persistent desire or unsuccessful efforts to cut down or control drinking, and drinking despite physical/psychological problems) are both less persistent and less predictive of AD course among younger adults compared to older adults. CONCLUSIONS: These findings raise the possibility of elevated rates of false-positive AD among younger adults and suggest ways to improve the assessment of AD criteria.

RESUMO

OBJECTIVES: Negative ageism impacts on the well-being of older persons; therefore, its identification is important to generate interventions that allow its decrease. CENVE is a widely used instrument to evaluate stereotypes towards old age in Spanish. However, its factor structure in older population and its invariance between those over and under 60 years old have not been confirmed. The objectives of the study are to evaluate the psychometric properties of the instrument and its invariance by age and gender. METHODS: The total sample was 439 people with 54 % of people over 60. This was divided into two random subsamples. With the first subsample, a confirmatory factor analysis of the different models proposed was carried out until an adequate fit was achieved, which was confirmed with the second subsample. Then, the invariance of the instrument was evaluated with the total sample by age and gender. RESULTS: The revised CENVE consists of 15 items with a unifactorial structure that showed good psychometric properties. It presented good reliability, including a .92 Omega. In addition, it proved to be an invariant instrument according to age and gender, which allows comparison between groups. DISCUSSION AND IMPLICATIONS: The use of CENVE will allow the identification of ageist stereotypes, with which interventions can be carried out to reduce them, both in groups older and younger than 60. In addition, it can be useful to generate a discussion about ageism in different fields, such as professional training.

RESUMO

Trait markers, or intermediate phenotypes linking different units of analysis (self-report, performance) from the Research Domain Criteria (RDoC) matrix across populations is a necessary step in identifying at-risk individuals. In the current study, 150 healthy controls (HC) and 456 individuals with bipolar disorder (BD) Type I or II, NOS (not otherwise specified) or Schizoaffective BD completed self-report neuropsychological tests of inhibitory control (IC) and executive functioning. Bifactor analyses were used to examine the factor structure of these measures and to evaluate for invariance across groups. Bifactor analyses found modest convergence of items from neuropsychological tests and self-report measures of IC among HC and BD. The factor scores showed evidence of a general IC construct (i.e., subdomain) across measures. Importantly, invariance testing indicated that the same construct was measured equally well across groups. Groups differed on the general factor for three of the four scales. Convergence on a general IC factor and invariance across diagnosis supports the use of combined dimensional measures to identify clinical risk and highlights how prospective RDoC studies might integrate units of analysis.
