    Background

    The relationship between migration and mental health has been the subject of various investigations in the last few decades. These were mainly prompted by the finding of a higher prevalence of mental disorders among migrants or ethnic minorities compared to natives or fellow country-men without migratory experiences (Bhugra, 2003; Cantor-Graae & Selten, 2005; de Wit et al., 2008; Fearon et al., 2006; Hutchinson & Haasen, 2004). Despite this, only a few studies have described migrants psychopathological features, mostly analysing some isolated symptoms (Familiar, Borges, Orozco & Medina-Mora, 2011; Lau, Cheng, Chow, Ungvari & Leung, 2009; Ritsner & Ponizovsky, 1998; Velthorst et al., 2011) or specific clinical populations, such as refugees and asylum seekers (Birman & Tran, 2008; Dobricki, Komproe, de Jong & Maercker,

    2010; Laban, Gernaat, Komproe & DeJong, 2007; Montgomery, 2008; Nickerson, Bryant, Steel, Silove & Brooks, 2010; Norredam, Jensen & Ekstrm, 2011; Porter & Haslam, 2005).

    Understanding psychopathology in migrants: A mixed categorical- dimensional approach

    AbstractBackground: Literature on mental disorders in migrants is constantly increasing. Only a few studies describe psychopathological dimensions in migrants over their nosographic diagnoses; however, there is a growing literature about the greater utility of a categorical-dimensional approach, rather than a solely categorical approach, in the understanding of mental disorders. The aim of this paper is to describe the phenomenology of mental disorders in migrants referred to the Transcultural Psychiatric Team of Bologna (BoTPT), by analysing the psychopathological dimensions that underlie their clinical diagnoses.Methods: We recruited all migrants who attended the BoTPT between May 1999 and July 2009. The psychopathological assessment was conducted with the Association for Methodology and Documentation in Psychiatry (AMDP) and clinical diagnoses were formulated according to ICD-10. We proceeded through a two-step analysis: (1) comparing the prevalence rates of psychopathological symptoms across diagnoses; then (2) conducting a factor analysis to assess how those symptoms configure psychopathological dimensions and how these dimensions underlie clinical diagnoses.Results: As expected, we found significant associations between diagnoses and the prevalence of their core psychopathological symptoms. Factor analysis revealed a strong polymorphism of the psychopathological presentation of mental disorders and unexpectedly showed that in each diagnostic cluster, the first extracted factor was not composed of core symptoms.Conclusions: A mixed categorical-dimensional approach seems to improve the description of the psychopathology among migrants, as it adds relevant information regarding psychopathological dimensions useful to the understanding of the peculiar clinical expressivity of our patients.

    The scarcity of studies describing psychopathology in migrants may represent an important limit to the compre-hension of their mental diseases. Actually, several studies show possible misdiagnoses of mental disorders in migrant patients (Charalabaki, Bauwens, Stefos, Madianos & Mendlewicz, 1995; Haasen, Yagdiran, Mass & Krausz, 2000; Lin & Cheung, 1999), probably due to peculiar clini-cal presentation and/or expression of suffering across dif-ferent cultures (Kirmayer, 2001; Kirmayer & Looper, 2006). Psychopathological exploration is important for the understanding of mental disorders in people with different cultural backgrounds as they may challenge the borders of Western nosography through a peculiar codification of suf-fering. In the last decades, the concept of culture-bound syndromes (CBS) was introduced in clinical psychiatry as an attempt to better account for the clinical peculiarity of some mental disorders found in specific geographical regions or populations: CBS is a broad rubric that encom-passes certain behavioral, affective and cognitive manifes-tations seen in specific cultures, and would allow a proper labelling and management of clinical pictures that may not be linked to a particular diagnostic category (Balhara, 2011, p. 210). However, CBS still represents a further categoriza-tion of migrants psychic disease.

    Few studies adopt a dimensional approach, while there is wide evidence about the greater utility of a categorical-dimensional approach, rather than a solely categorical approach, in the understanding of mental disorders in psy-chiatric patients (Demjaha et al., 2009; Egli, Riedel, Mller, Strauss & Lge, 2009; Krueger & Bezdjian, 2009; Lge, Egli, Riedel, Strauss & Mller, 2011; Lecrubier, 2008; Mller, 2008; Mller et al., 2011). These evidences recall the well-known debate about whether the categorical nosography sacrifices validity on the altar of reliability (Mullen, 2007, p. 113), and how the diagnostic paradigm, with its dehumanizing impact and its dryly empirical approach (Andreasen, 2007), would neither address the basic mandate of medicine (Kirmayer, 2005) nor be useful for research (Andreasen, 2007).

    The aim of our study is to describe the phenomenology of mental disorders of migrants referred to the Bologna Transcultural Psychiatric Team (BoTPT) by analysing the psychopathological configurations of their clinical diagno-ses. In particular, we aim to assess: (1) the prevalence of psychopathological symptoms in patients clinical diagno-ses; and (2) how those symptoms configure psychopatho-logical dimensions that underlie clinical diagnoses.

    Methods

    Study setting

    The Bologna West Community Mental Health Centre (CMHC) has developed one of the first projects in Italy which prioritises cultural competence at primary and

    secondary levels of care: the BoTPT (Tarricone et al., 2011). The BoTPT is composed of Bologna West CMHC mental health operators who dedicate part of their work to migrant psychiatric consultation. In the most difficult cases, the BoTPT team directly delivers psychiatric and psychoso-cial treatment to migrants; in other cases, the BoTPT team provides consultation geared towards identifying the mental and psychosocial needs of migrants, and then redirects patients within the CMHC and other services. Core person-nel includes psychiatrists as well as social workers, psychiat-ric nurses, residents in psychiatry and medical anthropologists. If needed, a cultural mediator joins the multi-professional team. All migrants, with or without papers, and regardless of gender, age, country of origin and legal status (regular or irregular), can have access to the service.
