RESUMO

BACKGROUND: Childhood and adolescent trauma is a risk factor for developing psychosis-spectrum disorders. The current study aimed to assess how childhood trauma might predict psychosis symptomatology, and how patients' beliefs of whether trauma is the cause of psychosis might affect this association. METHODS: Ninety-six first-episode psychosis patients were assessed for childhood traumatic experiences with the Brief Betrayal Trauma Survey, and for psychosis symptoms with the Positive and Negative Syndrome Scale. RESULTS: Non-interpersonal trauma predicted higher positive symptoms, whereas more trauma domains experienced predicted lower negative symptoms. Almost half of the participants believed trauma to be related to psychosis, were 12 times more likely to reexperience trauma through psychosis, and had higher excitative and emotional symptoms. Non-interpersonal trauma also predicted higher positive symptoms in this group. Those who did not believe trauma to be the cause of psychosis had higher negative symptoms, and a negative dose-response was found for negative and disorganised symptoms, in which more trauma domains experienced predicted lower scores. CONCLUSIONS: Results imply two traumagenic pathways to psychosis, one characterised by positive, excitative, and emotional symptoms, and one negative subtype, characterised by negative and disorganised symptoms. Clinical implications for how findings might contribute to better treatments are discussed.

RESUMO

BACKGROUND: Disrupted metacognition is implicated in development and maintenance of negative symptoms, but more fine-grained analyses would inform precise treatment targeting for individual negative symptoms. AIMS: This systematic review identifies and examines datasets that test whether specific metacognitive capacities distinctly influence negative symptoms. MATERIALS & METHODS: PsycINFO, EMBASE, Medline and Cochrane Library databases plus hand searching of relevant articles, journals and grey literature identified quantitative research investigating negative symptoms and metacognition in adults aged 16+ with psychosis. Authors of included articles were contacted to identify unique datasets and missing information. Data were extracted for a risk of bias assessment using the Quality in Prognostic Studies tool. RESULTS: 85 published reports met criteria and are estimated to reflect 32 distinct datasets and 1623 unique participants. The data indicated uncertainty about the relationship between summed scores of negative symptoms and domains of metacognition, with significant findings indicating correlation coefficients from 0.88 to -0.23. Only eight studies investigated the relationship between metacognition and individual negative symptoms, with mixed findings. Studies were mostly moderate-to-low risk of bias. DISCUSSION: The relationship between negative symptoms and metacognition is rarely the focus of studies reviewed here, and negative symptom scores are often summed. This approach may obscure relationships between metacognitive domains and individual negative symptoms which may be important for understanding how negative symptoms are developed and maintained. CONLCLUSION: Methodological challenges around overlapping participants, variation in aggregation of negative symptom items and types of analyses used, make a strong case for use of Individual Participant Data Meta-Analysis to further elucidate these relationships.

RESUMO

PURPOSE: Negative symptoms are a persistent, yet under-explored problem in psychosis. Disturbances in metacognition are a potential causal factor in negative symptom development and maintenance. This meta-analysis uses individual participant data (IPD) from existing research to assess the relationship between negative symptoms and metacognition treated as summed scores and domains. METHODS: Data sets containing individuals with negative symptoms and metacognition data, aged 16+ with psychosis, were identified according to pre-specific parameters. IPD integrity and completeness were checked and data were synthesized in two-stage meta-analyses of each negative symptoms cluster compared with metacognition in seemingly unrelated regression using restricted maximum likelihood estimation. Planned and exploratory sensitivity analyses were also conducted. RESULTS: Thirty-three eligible data sets were identified with 21 with sufficient similarity and availability to be included in meta-analyses, corresponding to 1301 participants. The strongest relationships observed were between summed scores of negative symptoms and metacognition. Metacognitive domains of self-reflectivity and understanding others' minds, and expressive negative symptoms emerged as significant in some meta-analyses. The uncertainty of several effect estimates increased significantly when controlling for covariates. CONCLUSIONS: This robust meta-analysis highlights the impact of using summed versus domain-specific scores of metacognition and negative symptoms, and relationships are not as clear-cut as once believed. Findings support arguments for further differentiation of negative symptom profiles and continued granular exploration of the relationship between metacognition and negative symptoms.

RESUMO

BACKGROUND: The evidence for manualized psycho-educative family intervention (FI) in first-episode psychosis (FEP) is well-established to reduce relapse and caregiver distress. Less is known, however, about type and duration of FI. AIM: To compare two different types of manualized family interventions for FEP: Multi-Family Groups (MFG) and Single-Family Intervention (SFI). METHODS: This was a prospective, quasi-experimental cohort study of all participants of an early psychosis service (OPUS) with an ICD-10 diagnosis of F20 to F29 (excl. F21), aged 18 to 35 years, in Psychiatry Region Zealand, Denmark, during a 2-year period. All service users and their relatives are offered FI, either MFG or SFI. Assessment of level of participation, psychopathology measured by The Positive and Negative Syndrome Scale (PANSS), remission status and relapses was carried out at 3-year follow up. RESULTS: We found no differences between the service users participating in SFI (N = 25) or MFG (N = 18) on number of readmissions or relapses after baseline or psychopathology. A binary logistic regression analysis on remission status at follow up showed a trend in favour of MFG. A surprisingly high proportion of the families did not receive an FI. CONCLUSIONS: SFI and MFG seem equally effective in an FEP programme. The low attendance of FI may be due to several issues-among others, the probability that the FI did not sufficiently match the needs of the service users. Further studies involving larger samples are needed, included randomized controlled trials and implementation studies.

RESUMO

Research suggests that people with first-episode psychosis (FEP) report more childhood traumas and have lower metacognitive abilities than non-clinical controls. Childhood trauma negatively affects metacognitive development in population studies, while the association remains largely unexplored in FEP populations. Metacognition refers to the identification of thoughts and feelings and the formation of complex ideas about oneself and others. This study hypothesized that childhood trauma would be associated with lower metacognitive abilities in people with FEP. In a representative sample of 92 persons with non-affective FEP, we assessed childhood trauma, metacognitive abilities and symptoms of psychosis. We used the Childhood Trauma Questionnaire (CTQ) and the Metacognitive Assessment Scale--Abbreviated which includes Self-reflectivity, Awareness of the Mind of the Other, Decentration and Mastery. Hierarchical regression analyses were performed with metacognitive domains as outcome variables and childhood traumas as independent variables, while controlling for age, gender, first-degree psychiatric illness and negative symptoms. We found few significant associations between the different types of childhood trauma and metacognitive domains, and they suggested childhood trauma are associated with better metacognitive abilities. Study limitations included the cross-sectional design and use of self-report measures. Future studies could preferably be prospective and include different measures of psychopathology and neuropsychology.

RESUMO

BACKGROUND: Long duration of untreated psychosis is associated with poor clinical and functional outcomes. However, few systematic attempts have been made to reduce this delay and little is known of service users' experience of early detection efforts. AIM: We explored service users' experience of an early detection service and transition to specialized treatment service, including pathway to care, understanding of illness and barriers to adequate assessment and treatment. METHODS: In-depth interviews were conducted with 10 service users (median age 21, range 18-27, five males and five females) who were diagnosed with a first-episode non-affective psychosis and who were seen by an early detection team (TOP) and currently enrolled in a specialized early intervention service for this disorder (OPUS). RESULTS: Stigma and fear of the 'psychiatric system' were reported as significant barriers to help seeking, while family members were seen as a crucial support. Moreover, the impact of traumatic events on the experience and development of psychosis was highlighted. Finally, participants were relieved by the prospect of receiving help and the early detection team seemed to create a trusting relationship by offering a friendly, 'anti-stigmatized' space, where long-term symptomatology could be disclosed through accurate and validating questioning. CONCLUSIONS: Early detection services have two important functions. One is to make accurate assessments and referrals. The other is to instil hope and trust, and to facilitate further treatment by forming an early therapeutic alliance. The findings in this study provide important insights into the way in which early detection efforts and pathways to care are experienced by service users, with direct implications for improving psychiatric services.

RESUMO

While metacognitive mastery seems to be closely linked to general functioning in persons with psychosis, little is known of metacognitive capacity of family members, who often play an important role in recovery and often report high levels of distress. We gathered assessments of metacognitive mastery from persons with first-episode psychosis and their mothers. We found that relatively higher overall mean mastery levels among the dyads, was related to less negative caregiver experiences, and less caregiver criticism. Greater levels of mastery were related to decreased duration of untreated psychosis. Clinical implications in terms of family intervention programmes repertoire are discussed.

RESUMO

There is growing evidence that metacognitive abilities which include the ability to synthesize knowledge regarding mental states in self and others and use this ability to solve problems are impaired in non-affective psychosis and associated with positive and negative symptom severity. We sought to (a) investigate the severity of metacognitive impairments in first-episode psychosis (FEP) compared to non-clinical controls and (b) explore associations with positive and negative symptom profiles. Ninety-seven people with FEP were compared to 101 control persons. Metacognition was assessed with interviews and the Metacognitive assessment scale-abbreviated. Four groups based on positive and negative symptoms were identified by cluster analysis and compared on metacognition, childhood adversities, duration of untreated psychosis and premorbid social and academic adjustment. Those with high levels of negative symptoms had poorer metacognitive abilities. Those with high positive and low negative symptoms did not have poorer metacognitive abilities than those with low positive and negative symptoms. None of the other predictors differed between the groups. The FEP group had poorer metacognitive abilities than the control group. Inclusion of metacognition in psychosis models may improve our understanding of negative symptoms, while previous findings of a relation with positive symptoms may have been confounded. Implications for current interventions are discussed.

RESUMO

Persons with schizophrenia spectrum disorders often report high levels of childhood trauma, which often exacerbates symptoms and impede the process of recovery. However, little is known about how these traumas are experienced by service users and how they are integrated in their life stories. To examine this, we conducted in-depth interviews with 15 service users with a diagnosis of a first-episode nonaffective psychosis who had reported 1 or more childhood traumas in self-report measures. There was an unexpected discrepancy between the number of traumas reported in self-report measures and in semistructured interviews, and many of the traumas did not seem integrated in their personal narratives. The analyses further revealed that although participants often described complicated and traumatic childhood environments, they still felt supported by their families; they reported a range of ways in which they tried to cope with and gain control of their psychotic disorder, and they described a general optimistic view of the future.

RESUMO

BACKGROUND: Reviews conclude that childhood and adolescence sexual, physical, emotional abuse and emotional and physical neglect are all risk factors for psychosis. However, studies suggest only some adversities are associated with psychosis. Dose-response effects of several adversities on risk of psychosis have not been consistently found. The current study aimed to explore adversity specificity and dose-response effects of adversities on risk of psychosis. METHOD: Participants were 101 persons with first-episode psychosis (FEP) diagnosed with ICD-10 F20 - F29 (except F21) and 101 non-clinical control persons matched by gender, age and parents' socio-economic status. Assessment included the Childhood Trauma Questionnaire and parts of the Childhood Experience of Care and Abuse Questionnaire. RESULTS: Eighty-nine percent of the FEP group reported one or more adversities compared to 37% of the control group. Childhood and adolescent sexual, physical, emotional abuse, and physical and emotional neglect, separation and institutionalization were about four to 17 times higher for the FEP group (all p<0.01). The risk of psychosis increased two and a half times for each additional adversity. All associations between specific adversities and psychosis decreased when they were adjusted for other adversities. CONCLUSION: Our findings suggest that there is a large shared effect of adversities on the risk of psychosis. Contrary to the call for further research into specific adversities, we suggest a search for mechanisms in the shared effects of traumatization. Clinical implications are thorough assessment of adversities and their possible effects.

RESUMO

BACKGROUND: In first-episode psychosis, the family is considered an important part in the recovery process. This is often accompanied by significant distress, which is acknowledged in numerous studies. However, little is known about the psychological factors involved. METHOD: One hundred and twenty-seven caregivers of persons with first-episode psychosis completed a series of questionnaires aimed at investigating the contribution of expressed emotion and metacognitions to caregiver distress. RESULTS: Linear mixed model analysis found that emotional over-involvement and metacognitions independently predicted caregiver distress. Mediation analysis using bootstrapping showed that emotional over-involvement could be seen as mediating the effect of metacognitions on distress. CONCLUSION: The current study is a first step towards understanding the role of metacognitions in caregiver distress, thus opening up for the possibility of using interventions from 'contextual behaviour therapies'. Implications and future studies are discussed. KEY PRACTITIONER MESSAGE: This study is the first attempt to address caregiver concerns from the perspective of contextual cognitive behavioural therapy. The metacognitive framework for caregiver distress in first-episode psychosis may help develop new therapeutic interventions to better support families. The study proposes a psychological understanding of emotional over-involvement and caregiver distress.
