Psychometric properties of the Trauma and Distress Scale, TADS, in an adult community sample in Finland
Background: There is increasing evidence that a history of childhood abuse and neglect is not uncommon among individuals who experience mental disorder and that childhood trauma experiences are associated with adult psychopathology. Although several interview and self-report instruments for retrospective trauma assessment have been developed, many focus on sexual abuse (SexAb) rather than on multiple types of trauma or adversity.Methods: Within the European Prediction of Psychosis Study, the Trauma and Distress Scale (TADS) was developed as a new self-report assessment of multiple types of childhood trauma and distressing experiences. The TADS includes 43 items and, following previous measures including the Childhood Trauma Questionnaire, focuses on five core domains: emotional neglect (EmoNeg), emotional abuse (EmoAb), physical neglect (PhyNeg), physical abuse (PhyAb), and SexAb. This study explores the psychometric properties of the TADS (internal consistency and concurrent validity) in 692 participants drawn from the general population who completed a mailed questionnaire, including the TADS, a depression self-report and questions on help-seeking for mental health problems. Inter-method reliability was examined in a random sample of 100 responders who were reassessed in telephone interviews.Results: After minor revisions of PhyNeg and PhyAb, internal consistencies were good for TADS totals and the domain raw score sums. Intra-class coefficients for TADS total score and the five revised core domains were all good to excellent when compared to the interviewed TADS as a gold standard. In the concurrent validity analyses, the total TADS and its all core domains were significantly associated with depression and help-seeking for mental problems as proxy measures for traumatisation. In addition, robust cutoffs for the total TADS and its domains were calculated.Conclusions: Our results suggest the TADS as a valid, reliable, and clinically useful instrument for assessing retrospectively reported childhood traumatisation
Ethnic variations in duration of untreated psychosis: report from the CRIS-FEP study
Objectives: There is inconsistent evidence on the influence of ethnicity on duration of untreated psychosis (DUP). We investigated ethnic differences in DUP in a large epidemiological dataset of first episode psychosis patients in an inner city area of south London, UK. Methods: We analysed data on 558 first episode psychosis patients at the South London and Maudsley NHS Trust, between 2010 and 2012. We performed multivariable logistic regression to estimate the odds of a short DUP (≤ 6 months) by ethnic group, controlling for confounders. Results: There was no evidence that ethnicity is associated with duration of untreated psychosis. However, we found evidence that a short DUP was strongly associated with age, living circumstances, and pathways to care variables (involuntary admission, out of office hour contact, accident and emergency referral, criminal justice agency referral and family involvement in help-seeking). Conversely, a long DUP was associated with report of social isolation, living alone, being single and General Practitioner referral. Conclusion: Our findings suggest that indicators of social isolation were associated with long DUP. Our data also show that pathways into care characteristics play significant role in DUP. Thus, the challenge of tackling the issue of timely access to EI under the new Access and Waiting Time standard for psychosis requires a multilevel approach, including joint working with communities, public awareness of psychosis, less restrictive referral pathways and adequate resourcing of early intervention for psychosis services. These will go a long way in addressing patients’ needs rather than be determined by service structures
Perceived negative attitude of others as an early sign of psychosis
Aim. - Risk of psychosis is defined by the presence of positive psychotic-like symptoms, by subtle self-perceived cognitive and perceptual deficiencies, or by decreased functioning with familial risk of psychosis. We studied the associations of psychiatric outpatients' self-reported functioning and interpersonal relationships with vulnerability to and risk of psychosis. Methods. - A total of 790 young patients attending psychiatric outpatient care completed the PROD screen [Heinimaa M, Salokangas RKR, Ristkari T, Plathin M, Huttunen J, Ilonen T, et al. PROD-screen - a screen for prodromal symptoms of psychosis. Int J Meth Psychiatr Res 2003; 12:92-04.], including questions on functioning, interpersonal relationships and subtle specific (psychotic-like) and non-specific symptoms. Vulnerability to psychosis was assessed employing the patient's written descriptions of specific symptoms. Of the patients vulnerable to psychosis, those at current risk of psychosis were assessed using the Bonn Scale for Assessment of Basic Symptoms [Schultze-Lutter F, Klosterkotter J. Bonn scale for assessment of basic symptoms - prediction list, BSABS-P. Cologne: University of Cologne; 2002] and the Structured Interview for Positive symptoms [Miller TJ, McGlashan TH, Rosen JL, Somjee L, Markovich PJ, Stein K, et al. Prospective diagnosis of the initial prodrome for schizophrenia based on the structured interview for prodromal syndromes: preliminary evidence of interrater reliability and predictive validity. Am J Psychiatry 2002; 159:863-65.]. Results. - In all, 219 patients vulnerable to and 55 patients at current risk of psychosis were identified. Vulnerability to psychosis was associated with all items of functioning and interpersonal relationships. Current risk of psychosis, however, was associated only with the Subjectively reported negative attitude of others. Negative attitude of others was also associated with feelings of reference at both vulnerability and risk levels. Conclusion. - The subjective experience of negative attitude of others towards oneself may be an early indicator of psychotic development. (C) 2009 Elsevier Masson SAS. All rights reserve
Self-labelling and stigma as predictors of attitudes towards help-seeking among people at risk of psychosis: 1-year follow-up
Duration of unspecific prodromal and clinical high risk states, and early help-seeking in first-admission psychosis patients
Clinical High-Risk for Psychosis Syndromes among Swiss and German Youth and Young Adults: Early Identification and Intervention
In Germany, clinical considerations of using patients’ self-reported early subtle disturbances for an early detection of developing psychosis before its first episode date back to the early twentieth century. These resulted in the formulation of the basic symptom concept that assumes that subtle, self-perceivable, but rarely externally perceivable disturbances in mental processes—the so-called basic symptoms—are the first psychopathological correlate of neurobiological processes underlying the development of psychoses, while attenuated and frank psychotic symptoms develop later in the course of the disorder as a result of inadequate coping with basic symptoms as well as other symptoms and stressors. Thus, both in Germany and Switzerland, systematic research on early detection and intervention in psychosis has mainly considered both basic symptom and ultrahigh risk criteria. Their combined consideration resulted in the first-ever staging model setting out an early and a late risk stage and, relatedly, a staged intervention model much in line with recent recommendations for intervention in a clinical high risk state by the European Psychiatric Association. Based on a first meta-analysis of single risk criteria, the basic symptom criterion cognitive disturbances and the symptomatic ultrahigh risk criteria were alternatively recommended for the detection of a clinical high risk syndrome by the European Psychiatric Association. Furthermore, research in Switzerland and Germany has focused on developmental issues and the general population, indicating that an onset-revised Attenuated Psychosis Syndromes might have clinical meaning in the general population, in particular in adults, in whom, however, it is infrequent
