Different personality profiles in patients with cluster headache: a data-driven approach.

INTRODUCTION: Cluster headache (CH) is usually comorbid to mood spectrum disorders, but the psychopathological aspects are poorly explored. We aimed at identifying discrete profiles of personality traits and their association with clinical features. METHODS: Based on the personality scales of the Millon Clinical Multiaxial Inventory-III, principal component analysis (PCA) identified psychological patterns of functioning of 56 CH patients. PCA outcomes were used for hierarchical cluster analysis (HCA) for sub-groups classification. RESULTS: Eighty-seven percent of patients had personality dysfunctions. PCA found two bipolar patterns: (i) negativistic, sadic-aggressive, borderline, and compulsive traits were distinctive of the psychological dysregulation (PD) dimension, and (ii) narcissistic, histrionic, avoidant, and schizoid traits loaded under the social engagement (SE) component. PD was associated with disease duration and psychopathology. SE was related to educational level and young age. HCA found three groups of patients, and the one with high PD and low SE had the worst psychological profile. CONCLUSIONS: Personality disorders are common in CH. Our data-driven approach revealed distinct personality patterns which can appear differently among patients. The worst combination arguing against mental health is low SE and high PD. Linking this information with medical history may help clinicians to identify tailored-based therapeutic interventions for CH patients.

Profile of personality in frontal and temporal lobe epilepsy: A study using the Millon Clinical Multiaxial Inventory-III.

Personality disorders can influence and, along with cognitive deficits, compromise the quality of life of patients with epilepsy. This study evaluated personality traits and disorders in patients with frontal (FLE) or temporal lobe epilepsy (TLE) using the Millon Clinical Multiaxial Inventory-III with the aim to determine prevalent personality profiles. The results demonstrate the presence of particularly pronounced personality traits and disorders with prevalence of histrionic and obsessive-compulsive personality profiles, respectively, in FLE and TLE. These profiles may be related to different effects of pathophysiological and clinical aspects.

The Millon Clinical Multiaxial Inventory-IV (MCMI-IV) and Millon Adolescent Clinical Inventory-II (MACI-II) in Legal Settings.

The MCMI-IV and MACI-II are the most recent iterations of the primary Millon clinical inventories and have become well-established instruments over the course of multiple editions. The MCMI, in particular in its prior editions, and to a lesser extent, the original MACI, have joined the canon of commonly-used psychological instruments in several forensic settings, though they have been met with significant controversy. This controversy is due in large part to complicated and sometimes questionable psychometric and normative referencing qualities that evaluators may find difficult to defend in a court setting. On balance, the instruments, unlike many others, are also supported by a rich though often less-than-understood theoretical backbone which lends depth and explanatory power, but which also can further complicate addressing psycho-legal questions. The authors, representing a mixed perspective on the inventories, generally conclude that while the MCMI-IV and MACI-II rely on a rich theoretical framework, the peer-reviewed literature is virtually non-existent, the need to rely on their predecessor instruments' research literatures are limiting, and the modifying indices have questionable utility in the detecting of response bias. In addition, the normative data and underreporting response styles in family court evaluations cause problems for the MCMI-IV's use in such contexts.

Current Patterns of Training in Personality Assessment During Internship.

OBJECTIVE: Training in broad-based objective and projective personality assessments has been a mainstay of applied psychology. Stedman (2007) and Piotrowski (2015) have documented a decline in projective training during internship. This study investigated internship directors' current expectations regarding graduate school training with objective and projective instruments, their ratings of the importance of that training, and current training patterns with objective and projective instruments during internship. METHOD: Participants were 355 psychology internship programs, representing 46.1% of the Association of Psychology Postdoctoral and Internship Centers. RESULTS: Results indicated the following current internship training patterns: Minnesota Multiphasic Personality Inventory (68% to 51%), Personality Assessment Inventory (59% to 25%), Millon Clinical Multiaxial Inventory (51% to 34%), Rorschach (35 to 26%), story telling (41% to 19%), sentence completion (41% to 18%), and drawings (36% to 9%). Adult program directors reported higher percentages for objective tests; child program directors reported higher percentages for projective tests. CONCLUSION: A decreased valuation of projective techniques is now typical of current internship training programs.

Personality disorders in cluster headache: a study using the Millon Clinical Multiaxial Inventory-III.

A great deal of studies suggests that cluster headache (CH) patients are usually comorbid to anxiety-mood spectrum disorders and psychopathological symptoms; however, the personality profiles reported in the literature strictly depend on type of assessment used. Psychiatric comorbidities have been extensively studied in migraine and they are recognized to represent a major risk factor associated with poorer outcome, playing a role in the headache chronification process at once as cause and consequence of it. By contrast the incidence and role of psychopathological aspects in CH is still not clarified, insufficiently explored as the striking severity of such a physical pain apparently leaves no room to psychological explanations. The aim of the present study is to describe psychopathological aspects of CH patients by means of the Millon Clinical Multiaxial Inventory-III (MCMI-III), a psychological assessment tool compatible to Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) that correlates personality disorders (PDs) and clinical syndromes. We included all consecutive inward patients with CH between January 2014 and December 2016. Patients were evaluated using the MCMI-III a validated inventory assessing 14 PDs Scales (coordinate with DSM-IV Axis II disorders) and ten Clinical Syndrome Scales (coordinate with DSM-IV Axis I disorders). Twenty-six CH patients (24 chronic CH) were tested. Personality disorders were present in 92% of the patients. The most frequent PDs were: obsessive-compulsive (30.8%), histrionic (26.9%), narcissistic (11.5%), paranoid (11.5%) and avoidant (11.5%). According to the MCMI-III, patients with CH showed a high prevalence of personality disorders (Axis II-DSM-IV). PDs in CH patients can play an important role in determining CH course toward chronification. These preliminary results suggest that behavioral treatments can find room to support more conventional drug and neurostimulation therapies in these patients. In addition, the very high prevalence of PDs in our patients suggests that CH could in some cases be considered among the spectrum of somatoform and pain syndromes in patients with PDs.

International Adaptations of the Millon Clinical Multiaxial Inventory: Construct Validity and Clinical Applications.

This article examines the influence of the Millon Clinical Multiaxial Inventory (MCMI) as a clinical and research instrument beyond the borders of the United States. The MCMI's theoretical and empirical grounding, its alignment with the Diagnostic and Statistical Manual of Mental Disorders (DSM), and scales that can be interpreted both categorically and dimensionally, are the primary features that make the test attractive. We begin with studies that evaluated the construct equivalence of the different language adaptations. Data from the most widely researched non English-language forms (Danish, Dutch, and Spanish) show excellent comparability with Millon's original. Nevertheless, significant problems were noted in efforts to create clinical groups that would allow for equivalence of diagnostic accuracy when using the cutoff scores. Although dimensional aspects of the scale scores were not affected by this, the adapted measures might show attenuated diagnostic accuracy compared with Millon's original. Next, we present MCMI studies conducted in clinical settings to document where the adapted tests have made their greatest impact in the international literature. A wide variety of clinical applications demonstrated broad utility, and given the high number of issues addressed, we think Millon's influence will certainly stand the test of time in different domains and settings.

Evolution of the Millon Clinical Multiaxial Inventory.

Dr. Theodore Millon (1928-2014) was a primary architect for the personality disorders in the DSM-III, a structure that has endured into the DSM-5. His 1969 book, Modern Psychopathology, created an elegant framework into which the well-known personality prototypes could be fitted and understood. His theoretical work soon led into the creation of several psychological inventories, most notably the Millon Clinical Multiaxial Inventory (MCMI). The MCMI, now in preparation for its 4th major edition, has been a very popular instrument among clinicians. This article explores the history of the MCMI's development from its origins, through 2 distinct theoretical phases, and to its current status as the MCMI-IV is finalized.

Convergent validity of MCMI-III clinical syndrome scales.

OBJECTIVES: This study tested the convergent validity of the Millon Clinical Multiaxial Inventory-III (MCMI-III) clinical syndrome scales. DESIGN: Cross-sectional survey. METHODS: Using a sample of 186 substance abusers from one single town referred for assessment, convergent and discriminant validity of the MCMI-III and Mini International Neuropsychiatric Interview (MINI) diagnoses was conducted. Additional measures included the Montgomery-Åsberg Depression Rating Scale and the Beck Anxiety Inventory. RESULTS: A single Axis I factor based on the raw scores correlated adequately with the factor based on the other scales (r= .85), whereas the correlation between the factor based on the MCMI-III baserate scores was somewhat lower (r= .74), but still indicated substantial convergent validity. For individual disorders, area under the curve (AUC) analyses suggested that the convergent validity of the MCMI-III and the MINI was adequate. The raw score scales were superior to the baserate adjusted scores in all but one case. Discriminant validity was good for alcohol and drug dependence, moderate for major depression and delusion, and poor for thought disorder and anxiety. CONCLUSIONS: The MCMI-III clinical syndrome scales generally measure the constructs they were intended for. The data did not support that the adjustments used in calculating the baserate scores improved validity.

Integrating psychopathology and personality disorders conceptualized by the MMPI-2-RF and the MCMI-III: a structural validity study.

The Minnesota Multiphasic Personality Inventory-2-Restructured Form (Ben-Porath & Tellegen, 2008 ) Restructured Clinical scales and Higher Order scales were linked to the Millon Clinical Multiaxial Inventory-III (Millon, Millon, Davis, & Grossman, 2009 ) personality disorder scales and clinical syndrome scales in a Flemish/Dutch sample of psychiatric inpatients and outpatients, substance abuse patients, correctional inmates, and forensic psychiatric patients (N = 968). Structural validity of psychopathology and personality disorders as conceptualized by both instruments was investigated by means of principal component analysis. Results reveal a higher order structure with 4 dimensions (internalizing disorders, externalizing disorders, paranoid ideation/thought disturbance, and pathological introversion) that parallels earlier research on pathological personality dimensions as well as research linking pathological personality traits with mental disorders. Theoretical and clinical implications are considered.

Personality traits in patients with myotonic dystrophy type 2.

Myotonic dystrophy type 2 (DM2) is a multisystem disorder that affects many organs and systems, including the brain. The objective is to analyze personality patterns in myotonic dystrophy type 2 (DM2) compared to DM1 control group. The study comprised 27 consecutive genetically confirmed DM2 patients and control group of 44 DM1 patients. Personality traits were assessed with the Millon Multiaxial Clinical Inventory III (MMCI III). In DM2 group there were no scale with pathological scores, although compulsive and paranoid traits were the most prominent. DM2 patients had lower scores compared to DM1 patients in almost all scales. Pathological scores on clinical symptom scales were not observed, although anxiety scale almost approached this value. Patients with higher compulsive score had higher level of education (rho = +0.53, p < 0.01). On the other hand, higher paranoid score correlated with younger age at onset (rho = -0.34, p < 0.01) and lower educational level (rho = -0.26, p < 0.05). Our results did not show significant personality impairments in patients with DM2. However, following personality traits were predominant: compulsive (in patients with higher education) and paranoid (in patients with lower education and earlier age at onset). The most common clinical symptoms were anxiety and somatization.

Millon clinical multiaxial inventory III (MCMI-III) and communication styles in a sample of university students.

Despite the controversy generated by the conceptualization of personality disorders, it is well established that the inflexibility of coping styles and dysfunctional behaviors associated with them can lead to a considerable impairment in interpersonal relationships. Although communication is one of the most important processes in relating to others, few empirical studies have been undertaken on the influence of dysfunctional personality patterns on communication styles, which is the main objective of the present cross-sectional study. A total of 529 Spanish university students were assessed using the Millon Clinical Multiaxial Inventory III (MCMI-III), Millon, Davis, and Millon, 1997, and the Communicator Style Measure (Norton, 1978). Results show statistically significant relationships between different personality patterns and styles of communication and suggest that narcissistic, histrionic and compulsive patterns are related to positive communication styles in a non-clinical sample. The implications of this study are discussed.

[Prefrontal symptoms and personality disorders in substance abusers]. / Sintomatologia prefrontal y trastornos de la personalidad en adictos a sustancias.

INTRODUCTION: Neuroimaging findings associate personality traits and their disorders with an altered functioning of certain areas of the brain, especially in the frontal lobe. There is a need for instruments that can be applied in clinical practice to explore these relations based on their behavioural manifestations. PATIENTS AND METHODS: The sample was composed of 371 subjects with substance abuse/dependence. The Prefrontal Symptoms Inventory (PSI) and the Millon Clinical Multiaxial Inventory II (MCMI-II) were administered and diagnostic interviews were carried out to determine the existence of disorders affecting axis II (personality disorders). RESULTS: Criteria satisfying a diagnosis of some personality disorder were present in 43.9% of the sample. The results show a broad correlational pattern between the prefrontal symptoms scales and those of personality disorders. The variance in up to eight of the 13 scales of the MCMI-II is predicted in over 20%, based on the combination of scales from the PSI. The personality disorders diagnosed by means of a clinical interview present differential prefrontal symptomatological profiles that were consistent with what was expected. CONCLUSIONS: The results support the hypothesis of a relationship between the diagnosis of personality disorders and frontal malfunctioning, thus suggesting new lines for studying and approaching them in clinical practice. Such new paths could involve the use of cognitive rehabilitation to improve day-to-day functioning and modify the neurological substrates underlying personality disorders.

Can personality traits predict the future development of heart disease in hospitalized psychiatric veterans?

OBJECTIVE: To examine which personality traits are associated with the new onset of chronic coronary heart disease (CHD) in psychiatric inpatients within 16 years after their initial evaluation. We theorized that personality measures of depression, anxiety, hostility, social isolation, and substance abuse would predict CHD development in psychiatric inpatients. METHOD: We used a longitudinal database of psychological test data from 349 Veterans first admitted to a psychiatric unit between October 1, 1983, and September 30, 1987. Veterans Affairs and national databases were assessed to determine the development of new-onset chronic CHD over the intervening 16-year period. RESULTS: New-onset CHD developed in 154 of the 349 (44.1%) subjects. Thirty-one psychometric variables from five personality tests significantly predicted the development of CHD. We performed a factor analysis of these variables because they overlapped and four factors emerged, with positive adaptive functioning the only significant factor (OR=0.798, p=0.038). CONCLUSION: These results support previous research linking personality traits to the development of CHD, extending this association to a population of psychiatric inpatients. Compilation of these personality measures showed that 31 overlapping psychometric variables predicted those Veterans who developed a diagnosis of heart disease within 16 years after their initial psychiatric hospitalization. Our results suggest that personality variables measuring positive adaptive functioning are associated with a reduced risk of developing chronic CHD.

[Factorial dimensions of the Millon's MCMI-II in substance addicts]. / Dimensiones factoriales del cuestionario de Millon (MCMI-II) en adictos a sustancias.

The Millon Clinical Multiaxial Inventory II is a widely used questionnaire for the assessment of personality in clinical settings, especially in addictive behaviors. The aim of this study is to determine the underlying factorial structure of the MCMI-II in a sample of 1,106 drug-dependents who seek treatment. All participants completed the MCMI-II and the TCI-R. Multivariate exploratory factor analysis was performed. The results show that, in the MCMI-II, there is a main part that assesses symptoms of recent onset associated with the Axis I disorders, a scale that explores autolytic ideation, two scales that explore issues related to the use of alcohol and other drugs, two scales that assess normal personality traits, and seven scales that explore dysfunctional personality traits. Although the objective of the MCMI-II is the assessment of personality, the results indicate that the largest part of the questionnaire assesses not necessarily stable conditions and which have appeared recently. The scales measuring dysfunctional personality traits are combined to account for disorders without a clear match to the theory of reference. We conclude that, when using the MCMI-II with diagnostic purposes, one should consider the presence of unstable conditions that could artifactually increase the prevalence rates and the coexistence of personality disorders and addictive behaviors.

Classification accuracy of the Millon Clinical Multiaxial Inventory-III modifier indices in the detection of malingering in traumatic brain injury.

The present study used criterion groups validation to determine the ability of the Millon Clinical Multiaxial Inventory-III (MCMI-III) modifier indices to detect malingering in traumatic brain injury (TBI). Patients with TBI who met criteria for malingered neurocognitive dysfunction (MND) were compared to those who showed no indications of malingering. Data were collected from 108 TBI patients referred for neuropsychological evaluation. Base rate (BR) scores were used for MCMI-III modifier indices: Disclosure, Desirability, and Debasement. Malingering classification was based on the Slick, Sherman, and Iverson (1999) criteria for MND. TBI patients were placed in one of three groups: MND (n = 55), not-MND (n = 26), or Indeterminate (n = 26).The not-MND group had lower modifier index scores than the MND group. At scores associated with a 4% false-positive (FP) error rate, sensitivity was 47% for Disclosure, 51% for Desirability, and 55% for Debasement. Examination of joint classification analysis demonstrated 54% sensitivity at cutoffs associated with 0% FP error rate. Results suggested that scores from all MCMI-III modifier indices are useful for identifying intentional symptom exaggeration in TBI. Debasement was the most sensitive of the three indices. Clinical implications are discussed.

Relación entre tratamiento con hormona de crecimiento y perfiles de personalidad en mujeres con diagnóstico de Síndrome de Turner / Relationship between growth hormone treatment and personality profiles in women diagnosed with Turner Syndrome

El objetivo del presente trabajo fue identificar la existencia de perfiles distintivos en las escalas de personalidad en relación con la aplicación o no de hormona de crecimiento en 73 mujeres adultas con diagnóstico de Síndrome de Turner de Latinoamérica. Para ello se administró, en formato online, el Inventario Clínico Multiaxial de Millon II y un cuestionario clínico para recabar datos sobre la realización o no de tratamiento con hormona de crecimiento durante el desarrollo con el fin de omparar ambos grupos. Los resultados encontrados muestran que el grupo que no realizó tratamiento con hormona de crecimiento obtiene medias más altas en casi la totalidad de las escalas de personalidad básicas y patológicas en comparación con el grupo que sírealizó tratamiento, siendo dicha diferencia significativa en la escala esquizotípica. Esta escala se asocia con necesidades afectivas mínimas, aislamiento social y apego empobrecido. Estos resultados podrían dar cuenta que el tratamiento con hormona de crecimiento sería un factor positivo para esta población, favoreciendo el desarrollo de características de personalidad más adaptativas en relación a lo social.

The aim of this study was to identify the existence of distinctive profiles on the personality scales in relation to the application or not of the growth hormone in 73 adult women diagnosed with Turner Syndrome in Latin America. For it was administered, in online form, the Millon Clinical Multiaxial Inventory II and a clinical questionnaire to collect data on the realization or non-treatment with growth hormone during development in order to compare both groups. The results show that the group did not make growth hormone treatment gets highest averages in nearly all of the basic and pathological personality scales compared to the group that if he completed treatment, being such significant difference in schizotypal scale. This scale is associatedwith minimal emotional needs, social isolation and impoverished attachment. These results might note that treatment with growth hormone could be a positive factorfor this population, favoring the development of more adaptive personality characteristics in relation to the social aspects.

Aplicação do modelo de Rasch na medida de transtornos da personalidade / Application of the Rasch model in measuring personality disorders

OBJECTIVE: To describe item and person parameters obtained with the Rasch model, one of the item response theory models, in the assessment of personality disorders based on Millon's theory. METHOD: A total of 350 people participated in the study. Age ranged from 18 to 67 years (mean ± standard deviation = 27.02±10.13), and 71.7% of the participants (n = 251) were female. Of the 350 individuals, 21.1% (n = 74) answered affirmatively about being under psychiatric treatment and taking psychiatric medications. The Personality Disorders Dimensional Inventory (PDDI), an instrument designed to assess personality disorders according to Millon's theory, was applied to all participants. Data were analyzed using the Rasch model. RESULTS: Overall, analysis with the Rasch model revealed that the PDDI has adequate psychometric properties for the assessment of personality disorders. CONCLUSION: Among the contributions of item response theory models for clinical instruments, the Rasch person-item map deserves to be highlighted as a successful attempt to improve the understanding of clinical scores obtained in response to particular test items.

OBJETIVO: Descrever os parâmetros de itens e pessoas obtidos com o modelo de Rasch, um dos modelos da teoria de resposta ao item, na avaliação de transtornos da personalidade de acordo com a teoria de Millon. MÉTODO: Participaram do estudo 350 pessoas. A idade variou de 18 a 67 anos (média ± desvio padrão = 27.02±10.13), e 71.7% (n = 251) eram do sexo feminino. Dos 350 participantes, 21.1% (n = 74) responderam afirmativamente sobre estarem em tratamento psiquiátrico e utilizarem medicamento psiquiátrico. O Inventário Dimensional de Transtornos da Personalidade (IDTP), destinado à avaliação dos transtornos da personalidade com base na teoria de Millon, foi aplicado a todos os participantes. Os dados foram analisados por meio do modelo de Rasch. RESULTADOS: De modo geral, os resultados da análise por meio do modelo de Rasch revelaram que o IDTP tem parâmetros psicométricos adequados para a avaliação de transtornos da personalidade. CONCLUSÃO: Entre as contribuições da teoria de resposta ao item para instrumentos clínicos, o mapa de pessoas-itens do modelo Rasch merece destaque enquanto tentativa bem-sucedida de aumentar a compreensão das pontuações clínicas obtidas em resposta a determinadas questões de um teste.
