Clinician and patient perspectives on the ontology of mental disorder: a qualitative study

Background

Psychiatry may face an "identity crisis" regarding its very foundations. The lack of consensus regarding the theoretical grounds of psychiatry as a discipline has its epicenter in the discussion about the Diagnostic and Statistical Manual (DSM). A growing number of academics considers the manual broken and a growing number of patients voice concern. Despite the huge body of critique, 90% of Randomized Trials are based on DSM definitions of mental disorder. Therefore, the question regarding the ontology of mental disorder remains: what is a mental disorder, exactly?

Aims

We aim to identify ontologies that live among patients and clinicians, evaluate the degree of consistency and coherence between clinician and patient views and contribute to the establishment of a novel ontological paradigm of mental disorder that is aligned with patients' and clinicians' perspectives.

Method

Eighty participants (clinicians/patients/clinicians with lived experience) were interviewed using a semi-structured interview, exploring their ideas on the ontology of mental disorder. This question was approached from different angles which led to comprising the interview schedule into different topics: "concept of disorder," "representation by DSM," "what is treated," "what is recovered," and "the right outcome measure." Interviews were transcribed and analyzed using inductive Thematic Analysis.

Results

From all subthemes and main themes, a typology was constructed in which six, not necessarily mutually exclusive, ontological domains were identified: mental disorder as (1) disease, (2) functional impairment, (3) loss of adaptation, (4) existential problem, (5) highly subjective phenomenon, and (6) deviation from social norms. Common ground for the sample groups was that mental disorder is about functional impairment. Although about a fourth of sample clinicians holds an ontological concept of disease, only a small percentage of patients and none of the clinicians with lived experience adhered to an ontological concept of disease. The sample clinicians most often understand mental disorder to be a highly subjective phenomenon, and individuals with lived experience (patients and clinicians) most often understand mental (dis)order to be adaptational in nature: an (im)balance of burden in relation to strengths, skills, and recourses.

Conclusion

The ontological palette is more diverse than what is taught about mental disorder in dominant scientific and educational discourse. There is a need to diversify the current, dominant ontology and make room for other ontologies. Investment is required in the development, elaboration and coming of age of these alternative ontologies, allowing them to reach their full potential and act as drivers of a landscape of promising novel scientific and clinical approaches.

Evaluating social (pragmatic) communication disorder

BACKGROUND

Social (pragmatic) communication disorder (SPCD) is a new diagnosis introduced by DSM-5, characterised by problems with verbal and nonverbal social communication. It is currently unclear whether SPCD is a valid diagnostic category, because little is known about the characteristics of those who meet its criteria. We sought to identify and describe cases of SPCD, to contribute to debates about its validity. We investigated whether the symptoms of SPCD cluster together to form a coherent syndrome that is distinct from autism spectrum disorder (ASD) in terms of its core and associated features.

METHODS

Participants were young people (N = 1,081, age range = 4-18 years) who had attended a specialist social communication disorders clinic for children with fluent language and normal-range intelligence. Standardised parent-report data were collected using the Developmental, Dimensional and Diagnostic Interview (3Di), Child Communication Checklist (CCC) and Strengths and Difficulties Questionnaire (SDQ). An algorithm was designed using 3Di and CCC items to implement DSM-5 SPCD criteria.

RESULTS

Eighty-eight young people met our criteria for SPCD, with 801 meeting DSM-5 ASD criteria and the remaining 192 having neither SPCD nor ASD ('clinical comparison group'). The core symptoms of SPCD co-occurred to a moderate degree (average interitem correlation = .22). SPCD cases had autistic social difficulties that were intermediate between ASD and the clinical comparison group. SPCD was associated with high rates of nonautistic psychopathology, with 63.5% scoring in the abnormal range of the SDQ's Total Problems scale.

CONCLUSIONS

We did not find evidence that SPCD is qualitatively distinct from ASD. Rather, it appears to lie on the borderlands of the autism spectrum, describing those with autistic traits that fall just below the threshold for an ASD diagnosis. SPCD may have clinical utility for identifying people with autistic traits that are insufficiently severe for ASD diagnosis, but who nevertheless require support.

The co-occurrence of autism and attention deficit hyperactivity disorder in children - what do we know?

Symptoms of attention deficit hyperactivity disorder (ADHD) and autistic spectrum disorder (ASD) often co-occur. The DSM-IV had specified that an ASD diagnosis is an exclusion criterion for ADHD, thereby limiting research of this common clinical co-occurrence. As neurodevelopmental disorders, both ASD and ADHD share some phenotypic similarities, but are characterized by distinct diagnostic criteria. The present review will examine the frequency and implications of this clinical co-occurrence in children, with an emphasis on the available data regarding pre-school age. The review will highlight possible etiologies explaining it, and suggest future research directions necessary to enhance our understanding of both etiology and therapeutic interventions, in light of the new DSM-V criteria, allowing for a dual diagnosis.

Detailed assessments of childhood adversity enhance prediction of central obesity independent of gender, race, adult psychosocial risk and health behaviors

OBJECTIVE

This study examined whether a novel indicator of overall childhood adversity, incorporating number of adversities, severity, and chronicity, predicted central obesity beyond contributions of "modifiable" risk factors including psychosocial characteristics and health behaviors in a diverse sample of midlife adults. The study also examined whether the overall adversity score (number of adversities × severity × chronicity) better predicted obesity compared to cumulative adversity (number of adversities), a more traditional assessment of childhood adversity.

MATERIALS/METHODS

210 Black/African Americans and White/European Americans, mean age=45.8; ±3.3 years, were studied cross-sectionally. Regression analysis examined overall childhood adversity as a direct, non-modifiable risk factor for central obesity (waist-hip ratio) and body mass index (BMI), with and without adjustment for established adult psychosocial risk factors (education, employment, social functioning) and heath behavior risk factors (smoking, drinking, diet, exercise).

RESULTS

Overall childhood adversity was an independent significant predictor of central obesity, and the relations between psychosocial and health risk factors and central obesity were not significant when overall adversity was in the model. Overall adversity was not a statistically significant predictor of BMI.

CONCLUSIONS

Overall childhood adversity, incorporating severity and chronicity and cumulative scores, predicts central obesity beyond more contemporaneous risk factors often considered modifiable. This is consistent with early dysregulation of metabolic functioning. Findings can inform practitioners interested in the impact of childhood adversity and personalizing treatment approaches of obesity within high-risk populations. Prevention/intervention research is necessary to discover and address the underlying causes and impact of childhood adversity on metabolic functioning.

Altered phospholipid metabolism in schizophrenia: a phosphorus 31 nuclear magnetic resonance spectroscopy study

Phospholipid (PL) metabolism is investigated by in vivo 31P magnetic resonance spectroscopy (MRS). Inconsistent alterations of phosphocholine (PC), phosphoethanolamine (PE), glycerophosphocholine (GPC) and glycerophosphoethanolamine (GPE) have been described in schizophrenia, which might be overcome by specific editing techniques. The selective refocused insensitive nuclei-enhanced polarization transfer (RINEPT) technique was applied in a cross-sectional study involving 11 schizophrenia spectrum disorder patients (SZP) on stable antipsychotic monotherapy and 15 matched control subjects. Metabolite signals were found to be modulated by cerebrospinal fluid (CSF) content and gray matter/brain matter ratio. Corrected metabolite concentrations of PC, GPC and PE differed between patients and controls in both subcortical and cortical regions, whereas antipsychotic medication exerted only small effects. Significant correlations were found between the severity of clinical symptoms and the assessed signals. In particular, psychotic symptoms correlated with PC levels in the cerebral cortex, depression with PC levels in the cerebellum and executive functioning with GPC in the insular and temporal cortices. In conclusion, after controlling for age and tissue composition, this investigation revealed alterations of metabolite levels in SZP and correlations with clinical properties. RINEPT 31P MRS should also be applied to at-risk-mental-state patients as well as drug-naïve and chronically treated schizophrenic patients in order to enhance the understanding of longitudinal alterations of PL metabolism in schizophrenia.

The history of 'Female Sexual Dysfunction' as a mental disorder in the 20th century

PURPOSE OF REVIEW

To provide an overview of conceptualizations of female sexual problems, and 'Female Sexual Dysfunction' in particular, throughout the 20th century, especially in relation to psychiatry and mental illness.

RECENT FINDINGS

In the past 15 years, there has been an increase in both medical and public discourse about 'Female Sexual Dysfunction'. I discuss a variety of literature sources dealing with female sexual problems, where these are understood variously as problems of developmental psychopathology, as technical phenomena to be resolved through education, or as medical problems to be addressed pharmaceutically.

SUMMARY

The stigma of mental illness shapes much recent discussion of female sexual problems, as does the legacy of the postwar critique of psychodynamic psychiatry.
