The Dimensionality of Proposed DSM-5 PTSD Symptoms in Trauma-Exposed Young Children.

A subtype of the posttraumatic stress disorder diagnosis for children 6 years and younger (PTSD-6Y) was introduced in the Diagnostic and Statistical Manual, Fifth Edition (DSM-5). This study utilized confirmatory factor analytic techniques to evaluate the proposed DSM-5 PTSD-6Y factor structure and criterion and convergent validity against competing models. Data for N = 284 (3-6 years) trauma-exposed young children living in New Orleans were recruited following a range of traumas, including medical emergencies, exposure to Hurricane Katrina and repeated exposure to domestic violence. The model was compared to DSM-IV, a 4-factor 'dysphoria' model that groups symptoms also associated with anxiety and depression, and alternate 1- and 2- factor models. Convergent validity was established against the Child Behavior Checklist (CBCL). Criterion related validity was established by comparing each model to a categorical rating of impairment. The Dysphoria and PTSD-6Y models offered the better accounts of symptom structure, although neither satisfied minimum requirements for a good fitting model. These two models also only showed small levels of convergence with CBCL dimensions. The 1-factor model offered the most compelling balance of sensitivity and specificity, with the 2-factor model and the Dysphoria model following closely behind. These CFA results do not support the symptom clusters proposed within the DSM-5 for PTSD-6Y. Although a 4-factor Dysphoria model offers a better overall account of clustering patterns (relative to alternate models), alongside acceptable sensitivity and specificity for detecting clinical impairment, it also falls short of being an adequate model in this younger age group.

Differential emotional abnormalities among schizotypy clusters.

Schizotypy, a multidimensional personality organization that reflects liability to develop schizophrenia-spectrum disorders, has been associated with a number of emotional abnormalities. Yet, the exact nature of any emotional abnormalities in schizotypy is relatively unclear. Using an ethnically diverse nonclinical sample (N = 2637), the present study identified homogenous clusters of individuals based on positive and negative schizotypy dimensions and explored three interrelated domains of emotion traits closely tied to functional outcomes and quality of life: affective experience, emotional awareness, and meta-level emotions. Consistent with prior research, four schizotypy clusters were obtained: low ("nonschizotypic"), high positive, high negative, and mixed (high positive and high negative). Regarding emotion correlates of schizotypy clusters, the mixed cluster was found to be the most deviant on almost all emotion traits (e.g., heightened trait negative affect, diminished emotional clarity), suggesting that the effects of positive and negative schizotypy are additive. In addition, positive and negative schizotypy clusters were associated with differential abnormalities, with the negative cluster presenting a wider range of, and more severe, impairments compared to the low cluster (e.g., reduced trait positive affect and reduced attention to positive emotion). The current study highlights the heterogeneity in emotional traits among schizotypy dimensions and the importance of studying the mixed schizotypy in terms of emotional dysfunction.

The necessity, validity, and clinical utility of a new diagnostic entity: Acute suicidal affective disturbance.

OBJECTIVE: Here we argue for the necessity, validity, and clinical utility of a new diagnostic entity, acute suicidal affective disturbance (ASAD). METHOD: We expand on the conceptual, clinical, and practical rationale for ASAD, propose its defining features, describe research results to date, and suggest avenues for future research. RESULTS: There is accruing evidence for the existence of a previously unclassified, rapid-onset mood disturbance that geometrically escalates and regularly results in life-threatening behavior. CONCLUSIONS: ASAD research may not only improve the field's understanding of suicidal behavior but also enhance clinical effectiveness and save lives.

Multicenter Validation of the Emotional State Instrument for Dialysis Patients.

BACKGROUND: The Emotional State Instrument for Dialysis Patients (ES-D) is a brief semistructured questionnaire to assess emotional distress in patients undergoing dialysis. It was designed to be administered by a healthcare provider. A previous study showed preliminary indicators of its content and face validity. OBJECTIVE: The aim of the current multicenter study was to explore the ES-D's psychometric properties. METHODS: A total of 605 patients with kidney disease undergoing dialysis (524 hemodialysis and 81 peritoneal dialysis) in 19 Spanish dialysis centers completed the ES-D, along with anxiety, depression (Hospital Anxiety and Depression Scale), and resilience (Brief Resilience Scale) questionnaires. The 75 healthcare providers who performed the assessments completed a satisfaction survey. RESULTS: The ES-D showed adequate internal consistency (α = .73). Correlations between the ES-D scores and the scores for anxiety, depression, and resilience showed evidence of its convergent and concurrent validity. The receiver operating characteristic curve analyses showed that a cutoff of nine detected patients with moderate-to-severe emotional distress. According to these criteria, 35.4% of patients showed emotional distress. No significant differences were found between patients undergoing hemodialysis and peritoneal dialysis. The healthcare providers perceived the ES-D as useful for knowing the patients' emotional state, understanding patients' concerns, and establishing therapeutic relationships. CONCLUSIONS: The ES-D is a useful tool for healthcare providers to explore the emotional dimension of their patients. Thus, its development represents a step forward in the improvement of comprehensive assistance and the quality of life of patients with kidney disease undergoing dialysis.

The Multidimensional Emotional Disorder Inventory (MEDI): Assessing transdiagnostic dimensions to validate a profile approach to emotional disorder classification.

There has been limited progress evaluating the validity of dimensional approaches to emotional disorder classification. This has occurred in part because of a lack of standardized assessment tools developed with the specific intent of studying dimensional classification. The goal of the current study was to develop and validate the Multidimensional Emotional Disorder Inventory (MEDI) to efficiently assess nine empirically supported transdiagnostic dimensions proposed in the Brown and Barlow (2009) profile approach to emotional disorder classification: neurotic temperament, positive temperament, depression, autonomic arousal, somatic anxiety, social anxiety, intrusive cognitions, traumatic reexperiencing, and avoidance. The MEDI factor structure, reliability, and convergent/discriminant validity was evaluated in outpatients with emotional disorders (pilot sample = 227; validation sample = 780). The final 9-factor solution fit the data well. Intercorrelations among MEDI factors were consistent with previous research, and all MEDI dimensions had acceptable reliability. Correlations with common self-report questionnaires and DSM-5 diagnoses supported the convergent/discriminant validity of all nine MEDI dimensions. Collectively, these results support the use of 49-item MEDI in clinical research samples. The MEDI should be used in future research to evaluate the validity of the Brown and Barlow (2009) approach to emotional disorder classification. Because it provides an efficient assessment of several well-established emotional disorder traits and phenotypes, the MEDI also may have utility for general research or clinical purposes.

Taxometric Analysis of the Toronto Structured Interview for Alexithymia: Further Evidence That Alexithymia Is a Dimensional Construct.

Alexithymia is a clinically relevant personality construct characterized by difficulties identifying and describing feelings, externally oriented thinking, and impoverished imaginal processes. Previous taxometric investigations provided evidence that alexithymia is best conceptualized as a continuous dimension rather than a discrete type, at least when assessed with the self-report 20-Item Toronto Alexithymia Scale. The aim of the current study was to test the categorical versus dimensional structure of alexithymia using the recently developed Toronto Structured Interview for Alexithymia. Three nonredundant taxometric procedures (MAXCOV, MAMBAC, and L-Mode) were performed on the Toronto Structured Interview for Alexithymia subscale scores from a multinational sample of 842 adults. All taxometric procedures produced unambiguously dimensional solutions, providing further evidence that the core alexithymia features are continuously distributed in the population. Discussion focuses on the theoretical, assessment, and clinical implications of these findings for the alexithymia construct.

Hyperactivation and hypoactivation affective dysregulation symptoms are integral in complex posttraumatic stress disorder: Results from a nonclinical Israeli sample.

OBJECTIVES: The current study sought to further assess the nature of the affect dysregulation (AD) cluster of the International Classification of Diseases-11 (ICD-11) proposal for complex posttraumatic stress disorder (CPTSD) in a nonclinical sample. METHODS: An online survey sample from Israel (n = 618) completed a disorder-specific measure (International Trauma Questionnaire) of PTSD and CPTSD along with the Life Events Checklist and the World Health Organization Well-Being Index. RESULTS: Estimated prevalence rates of PTSD and CPTSD were 9.2% and 1.0%, respectively. Confirmatory factor analysis results indicated that AD symptoms are better conceived as two correlated dimensions of hyperactivation and hypoactivation symptoms. Latent class analysis results indicated that CPTSD was clearly distinguishable from PTSD. CPTSD class membership was associated with higher levels of traumatization and poorer psychological well-being scores. CONCLUSIONS: Findings support the discriminant validity of the ICD-11 proposals for PTSD and CPTSD in a nonclinical sample using a disorder-specific measure. The results provide further evidence that the final symptom profile for CPTSD in ICD-11 should model the AD cluster using both hyperactivation and hypoactivation symptoms.

Affective auditory stimulus database: An expanded version of the International Affective Digitized Sounds (IADS-E).

Using appropriate stimuli to evoke emotions is especially important for researching emotion. Psychologists have provided several standardized affective stimulus databases-such as the International Affective Picture System (IAPS) and the Nencki Affective Picture System (NAPS) as visual stimulus databases, as well as the International Affective Digitized Sounds (IADS) and the Montreal Affective Voices as auditory stimulus databases for emotional experiments. However, considering the limitations of the existing auditory stimulus database studies, research using auditory stimuli is relatively limited compared with the studies using visual stimuli. First, the number of sample sounds is limited, making it difficult to equate across emotional conditions and semantic categories. Second, some artificially created materials (music or human voice) may fail to accurately drive the intended emotional processes. Our principal aim was to expand existing auditory affective sample database to sufficiently cover natural sounds. We asked 207 participants to rate 935 sounds (including the sounds from the IADS-2) using the Self-Assessment Manikin (SAM) and three basic-emotion rating scales. The results showed that emotions in sounds can be distinguished on the affective rating scales, and the stability of the evaluations of sounds revealed that we have successfully provided a larger corpus of natural, emotionally evocative auditory stimuli, covering a wide range of semantic categories. Our expanded, standardized sound sample database may promote a wide range of research in auditory systems and the possible interactions with other sensory modalities, encouraging direct reliable comparisons of outcomes from different researchers in the field of psychology.

Los confusos límites del trastorno límite / The blurry boundaries of Bordeline Personality Disorder

Desde los orígenes del concepto borderline, podemos presenciar el descontento que existe entre profesionales y pacientes ante tal denominación. Muestra de ello es la diversidad de apelativos que se le han adjudicado al trastorno límite de la personalidad (TLP), todos ellos en torno a la idea de algo fronterizo o en tierra de nadie. Por otro lado, tampoco hay acuerdo acerca del concepto ni del grupo nosológico al que se debe adscribir, habiéndose enmarcado en diversos grupos nosológicos en función de los rasgos que se consideran básicos o de aspectos de su etiología. En la actualidad sigue reclamándose un cambio de nombre, así como que deje de considerarse un trastorno de personalidad como el resto de los descritos en los clusters del sistema DSM. En esta exposición no nos centraremos en la descripción sintomatológica del cuadro TLP, sino que, mediante una revisión bibliográfica, planteamos lo propio o impropio de la denominación del trastorno y, también, la confusión que desde sus inicios suscita el concepto límite (AU)

From the beginning of the borderline concept, we have witnessed the disapproval of clinicians and patients upon this denomination. An evidence of this is the wide range of names that have been attributed to the borderline personality disorder, all of them suggesting the idea of something in the border or in no man´s land. On the other hand, no agreement has yet been reached, either on the concept or on the nosological group to which it has been ascribed, having been framed in several nosological groups according to the traits that were considered as essential or to some aspects of its etiology. A change of name and the fact of being no longer considered a personality disorder as those described in the DSM are still demanded. In this exposition, a literature review was carried out in order to examine the appropriateness or inappropriateness of its denomination as well as the confusion that the borderline concept has arisen from its beginnings (AU)

Irritability in child and adolescent psychopathology: An integrative review for ICD-11.

In preparation for the World Health Organization's development of the Eleventh Revision of the International Classification of Diseases and Related Health Problems (ICD-11) chapter on Mental and Behavioral Disorders, this article reviews the literature pertaining to severe irritability in child and adolescent psychopathology. First, research on severe mood dysregulation suggests that youth with irritability and temper outbursts, among other features of hyperactivity and arousal, demonstrate cross-sectional correlates and developmental outcomes that distinguish them from youth with bipolar disorder. Second, other evidence points to an irritable dimension of Oppositional Defiant Disorder symptomatology, which is uniquely associated with concurrent and subsequent internalizing problems. In contrast to the Diagnostic and Statistical Manual of Mental Disorders' (5th ed.) Disruptive Mood Dysregulation Disorder, our review of the literature supports a different solution: a subtype, Oppositional Defiant Disorder with chronic irritability/anger (proposal included in Appendix). This solution is more consistent with the available evidence and is a better fit with global public health considerations such as harm/benefit potential, clinical utility, and cross-cultural applicability. Implications for assessment, treatment, and research are discussed.

Residential Treatment and the Invention of the Emotionally Disturbed Child in Twentieth-Century America.

In the 1930s, children who were violent, depressed, psychotic, or suicidal would likely have been labeled delinquent and sent to a custodial training school for punitive treatment. But starting in the 1940s, a new group of institutions embarked on a new experiment to salvage and treat severely deviant children. In the process, psychiatrists, psychologists, and social workers at these residential treatment centers (RTCs) made visible, and indeed invented, a new patient population. This article uses medical literature, popular media, and archival sources from several RTCs to argue that staff members created what they called the "emotionally disturbed" child. While historians have described the identification of the mildly "troublesome" child in child guidance clinics, I demonstrate how a much more severely ill child was identified and defined in the process of creating residential treatment and child mental health as a professional enterprise.

Autism Spectrum Disorder in the DSM-5: Diagnostic Sensitivity and Specificity in Early Childhood.

Changes to the DSM-5 Autism Spectrum Disorder (ASD) criteria raised concerns among parents and practitioners that the criteria may exclude some children with Pervasive Developmental Disorder (PDD). Few studies have examined DSM-5 sensitivity and specificity in children less than 5 years of age. This study evaluated 185 children aged 20-55 months with DSM-IV PDD or developmental delay. Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule (ADOS) data was assigned to DSM-5 subdomains. Children displaying the required symptomatology were classified with DSM-5 ASD. DSM-IV clinical diagnoses were compared to DSM-5 classifications. Using combined ADI-R/ADOS information, sensitivity was .84 and specificity was .54. Comorbid behaviour and emotional problems were significantly lower in children with PDD that did not meet DSM-5 criteria.

[Measuring alexithymia in fibromyalgia: the need for a multimodal measurement method to replace the TAS-20]. / Alexithymie bij fibromyalgie: meetinstrumenten; argumenten voor een multimodale benadering.

BACKGROUND: In an earlier publication that investigated alexithymia in fibromyalgia, we showed the Toronto Alexithymia Scale was the only instrument being used to measure alexithymia. AIM: To find out which instruments are currently available for measuring alexithymia, to compare the psychometric properties of these instruments and to decide whether some of the test methods involved should be used to give extra value to alexithymia research. METHOD: We conducted a systematic review of the literature in Medline/PubMed with a number of search terms. We selected articles relating to psychometric properties of the tests performed and decided whether they could be influenced by negative affect. RESULTS: We found that 14 different instruments were used to measure alexithymia. From our evaluation we excluded tests which had weak psychometric properties or had been inadequately assessed. There remained three observation scales and two self-report questionnaires, which had been adequately validated and whose relative strengths and weaknesses were compared. CONCLUSION: In view of these findings, we recommend that in studies of alexithymia in fibromyalgia a multimodal measurement method should be used rather than only the tas-20.

Autorregulación emocional en el trastorno por déficit de atención/hiperactividad infantil y potenciales evocados P300 / Emotional self-regulation in infantile attention deficit hyperactivity disorder and P300 evoked potentials

Introduction. The difficulties that patients with attention deficit hyperactivity disorder (ADHD) have when it comes to emotional regulation have aroused a great deal of interest in recent years and there is a line of research working on the identification of the neurophysiological correlates. Aims. To analyse measures of emotional functioning and their correlation with the P300 component in a sample of children with ADHD with and without treatment. Patients and methods. The sample was made up of 71 children with ADHD, almost half of whom were taking some form of medication. The auditory potential P300 was analysed. The parents filled in a scale to assess executive behaviour at home, the Behaviour Rating Inventory of Executive Function (BRIEF), which the emotional self-regulation index and the emotional expression scale were taken from. Results. Significant correlations were found between the amplitude of the P300 and the emotional self-regulation index from the version of the BRIEF for preschoolers, and a relation was observed between P300 latency and the severity of the symptoms. Conclusions. The results highlight the usefulness of evoked potentials for the study of executive correlates and associated conditions in the day-to-day functioning of children with ADHD (AU)

[Hyperkinetic disorders in children and adolescents in Germany: administrative prevalence and regional differences regarding the frequency of diagnosis assignment]. / Hyperkinetische Störungen bei Kindern und Jugendlichen in Deutschland: Administrative Prävalenz und regionale Unterschiede in der Diagnosehäufigkeit.

OBJECTIVE: To analyse the administrative prevalence and regional differences in hyperkinetic disorder (HK) diagnoses in Germany. METHODS: The administrative prevalence of HK (ICD-10 F90) was analysed for 3,6 million children, up to 18 years old and in the whole year 2009 insured by the AOK, using health insurance data. Additionally, administrative prevalence changes between 2006 and 2008 were investigated. The prevalence analyses were differenciated according to postal code areas and regions of the associations of statutory health insurance physicians (SHIP-regions). RESULTS: The analyses revealed a continous increase of the administrative HK-prevalence between 2006 (2,8 %) and 2009 (3,8 %). The administrative prevalence was notably lower in the city states Bremen, Hamburg and Berlin, but rather high in four of five SHIP-regions in the New Laender. 14 % of children with HK were diagnosed with HK and ICD-10 F98.8. In 47 % these different diagnoses had been coded by different physicians. CONCLUSIONS: Regional differences in administrative prevalence rates and discrepancies in diagnosis coding by different physicians may indicate uncertainties regarding HK-diagnosis in routine health care. Future studies should analyse these associations more detailed.

Pediatric emotion dysregulation: biological and developmental evidence for a dimensional approach.

The following review article examines the value of a dimensional approach to research in relation to recent findings of child and adolescent emotion dysregulation. With the publication of the DSM-5, it is important to keep in mind that difficulties in pinpointing causal mechanisms may result from the collective grouping of different emotional deficits by diagnoses. Evidence available from studies examining pediatric emotion dysregulation indicate strengths in the dimensional approach for research, especially in light of developmental changes to neural activations of emotion regulation. Use of a dimensional approach in research appears to be an effective tactic that could pave the way for a better understanding of pediatric emotion dysregulation and thereby elucidate better treatments and outcomes for those with this behavioral deficit, regardless of diagnosis.

A test of the empirical network surrounding affective instability and the degree to which it is independent from neuroticism.

Affective instability (AI) is as a central component of a number of psychiatric disorders, but it has received relatively little empirical attention as an individual construct. The goal of the current study was to study AI in the context of a broad empirical network of relevant constructs and compare its pattern of relations with those generated by trait neuroticism, both of which were assessed using both self- and informant reports. In a sample of 343 college students, the present study examined the correlations generated by an AI factor (derived from a factor analysis of relevant scales) in comparison to neuroticism in relation to personality and etiological and outcome variables. An exploratory factor analysis revealed a one-factor structure of AI related to the experience of intense and changeable negative affect and subsequent physical and behavioral consequences. The correlations generated by self- and informant reports of AI with these external criteria were almost perfectly correlated with the correlations demonstrated by self- and informant reports of neuroticism. Self- and informant reports of AI generated a pattern of results consistent with its role in a number of psychological disorders that are associated with substantial impairment. The current data suggest that AI might be best conceived of as largely overlapping with neuroticism rather than as a distinct construct.

[Mixed states: evolution of classifications]. / États mixtes. Évolution des classifications.

The nosological position of mixed states has followed the course of classifying methods in psychiatry, the steps of the invention of the clinic, progress in the organization of care, including the discoveries of psychopharmacology. The clinical observation of a mixture of symptoms emerging from usually opposite clinical conditions is classical. In the 70s, a syndromic specification fixed the main symptom combinations but that incongruous assortment failed to stabilize the nosological concept. Then stricter criteriology was proposed. To be too restrictive, a consensus operates a dimensional opening that attempts to meet the pragmatic requirements of nosology validating the usefulness of the class system. This alternation between rigor of categorization and return to a more flexible criteriological option reflects the search for the right balance between nosology and diagnosis. The definition of mixed states is best determined by their clinical and prognostic severity, related to the risk of suicide, their lower therapeutic response, the importance of their psychiatric comorbidities, anxiety, emotional lability, alcohol abuse. Trying to compensate for the lack of categorical definitions and better reflecting the clinical field problems, new definitions complement criteriology with dimensional aspects, particularly taking into account temperaments.
