Objective: To evaluate the importance of phenomenological aspects of the cognitive rumination (CR) construct in current empirical psychiatric research. Method: We searched SciELO, Scopus, ScienceDirect, MEDLINE, OneFile (GALE), SpringerLink, Cambridge Journals and Web of Science between February and March of 2014 for studies whose title and topic included the following keywords: cognitive rumination; rumination response scale; and self-reflection. The inclusion criteria were: empirical clinical study; CR as the main object of investigation; and study that included a conceptual definition of CR. The studies selected were published in English in biomedical journals in the last 10 years. Our phenomenological analysis was based on Karl Jaspers' General Psychopathology. Results: Most current empirical studies adopt phenomenological cognitive elements in conceptual definitions. However, these elements do not seem to be carefully examined and are indistinctly understood as objective empirical factors that may be measured, which may contribute to misunderstandings about CR, erroneous interpretations of results and problematic theoretical models. Conclusion:Empirical studies fail when evaluating phenomenological aspects of the cognitive elements of the CR construct. Psychopathology and phenomenology may help define the characteristics of CR elements and may contribute to their understanding and hierarchical organization as a construct. A review of the psychopathology principles established by Jasper may clarify some of these issues. Keywords: Psychopathology, phenomenology, cognitive rumination. ResumoObjetivo: Verificar a importância de aspectos fenomenológicos relacionados ao construto de ruminação cognitiva (RC) nas pesquisas empíricas psiquiátricas atuais. Método: Foram pesquisadas as bases de dados SciELO, Scopus, ScienceDirect, MEDLINE, OneFile (GALE), SpringerLink, Cambridge Journals e Web of Science, entre fevereiro e março de 2014, buscando artigos cujo tópico ou título contivessem os seguintes termos-chave: ruminação cognitiva; escala de resposta ruminativa; e autorreflexão. Os critérios de inclusão foram: estudos clínicos empíricos; RC como principal objeto de pesquisa; e estudos que incluíssem uma definição conceitual de RC. Foram considerados apenas artigos em inglês publicados em periódicos biomédicos nos últimos 10 anos. Nossa análise fenomenológica se fundamentou na Psicopatologia Geral de Jaspers. Resultados: Os conceitos de RC atualmente encontrados nas pesquisas empíricas utilizam majoritariamente elementos fenomenológicos em suas definições. Entretanto, esses elementos cognitivos são indistintamente entendidos como elementos objetivos (empíricos), passíveis de mensuração, e não parecem ser cuidadosamente examinados. Este fato pode contribuir para uma compreensão enganosa sobre RC, além de favorecer a interpretação errônea de resultados e a elaboração de paradoxos teóricos problemáticos. Conclusão: As pesquisas empíricas atuais sobre RC falham ao avaliar os aspectos fenomenológicos inerentes ao...

BackgroundBackground: Phantom boarder (PB) is the sensation that someone uninvited is in the patient's home despite evidence to the contrary. It is mostly reported by patients with neurodegenerative disorders such as Alzheimer's disease, dementia with Lewy bodies or Parkinson's disease (PD). Presence hallucination (PH) is frequent in neurodegenerative disease, shares several aspects with PB, and is the sensation that someone is nearby, behind or next to the patient (when nobody is actually there). Recent work developed a sensorimotor method to robotically induce PH (robot-induced PH, riPH) and demonstrated that a subgroup of PD patients showed abnormal sensitivity for riPH. Objective Objective: We investigated if PD patients with PB (PD-PB) would (1) show elevated sensitivity for riPH that ( 2) is comparable to that of patients reporting PH, but not PB (PD-PH). Methods Methods: We studied the sensitivity of non-demented PD patients in a sensorimotor stimulation paradigm, during which three groups of patients (PD-PB; PD-PH; PD patients without hallucinations, PD-nPH) were exposed to different conditions of conflicting sensorimotor stimulation. ResultsResults: We show that PD-PB and PD-PH groups had a higher sensitivity to riPH (compared to PD-nPH). PD-PB and PD-PH groups did not differ in riPH sensitivity. Together with interview data, these behavioral data on riPH show that PB is associated with PH, suggesting that both share some underlying brain mechanisms, although interview data also revealed phenomenological differences. Conclusions Conclusions: Because PD-PB patients did not suffer from dementia nor delusions, we argue that these shared mechanisms are of perceptual-hallucinatory nature, involving sensorimotor signals and their integration.Patients with phantom boarder phenomenon (PB) report that someone uninvited has entered or lives in the patient's home, despite of evidence to the contrary. 1 The unsolicited visitor is mostly experienced by patients as an unfamiliar intruder with malevolent intentions (e.g., harm or rob the patient) or hassling behaviors (e.g., make noise), although the visitor may also be experienced as a friend or family member. [1][2][3][4] PB is clinically relevant as it occurs repeatedly, and is a compelling experience, which is often destabilizing for patients, caregivers, and their relationship. Furthermore, PB has been associated with earlier home placement and delirium. 5 PB is prevalent in several neurodegenerative diseases associated with dementia, such as dementia with Lewy bodies (DLB), 6,7 Alzheimer's disease (AD), 8,9 vascular dementia 10 and Parkinson's disease (PD). 6 PB is often described as the most common "delusion" (together with paranoid ideation) in such diseases, with Aarsland et al. 6 reporting PB in 41% of DLB and 17% of PD dementia (PDD) patients.Despite this clinical relevance, understanding of the involved brain mechanisms of PB remains limited and its "exact nosology (…) debatable". 11 In his initial clinical description, Rowan 1 described PB as a delusional ...
AimDelusions are a common symptom in schizophrenia. Some scales have been developed to measure delusional tendencies in healthy people, and nonpathological delusional thinking can occur even among these individuals. The existing scales measure the presence and frequency of delusional thoughts, distress levels, and confidence levels. However, these scales are limited because they do not consider the context of the delusions (i.e., where, with whom, and when). In this study, we developed a new scale that presents detailed scenes using illustrations and sentences and measures the tendency toward delusional interpretations.MethodsFactor analysis was conducted to confirm the factor structure of the new scale. To examine the validity of the scale, we analyzed the correlations between delusional tendencies and related variables and verified the consistency between the current scale and previously developed tools.ResultsFactor analysis confirmed that the new scale has a two‐factor structure, including “internal attribution and paranoid tendency” and “external attribution tendency.” The new scale was found to have acceptable reliability and validity. The internal attribution and paranoid tendency factor was negatively correlated with self‐esteem and decentering. Furthermore, the internal attribution and paranoid tendency factor showed a moderate positive correlation with depressive state and anxiety tendency and a very weak positive correlation with experiences of bullying or harassment.ConclusionThe correlations between the new scale and related variables confirmed the construct validity and replicated the results reported in previous studies. This new scale enables the measurement of delusional tendencies in healthy subjects based on the social context.
