Negative and positive childhood experiences across developmental periods in psychiatric patients with different diagnoses – an explorative study
BACKGROUND: A high frequency of childhood abuse has often been reported in adult psychiatric patients. The present survey explores the relationship between psychiatric diagnoses and positive and negative life events during childhood and adulthood in psychiatric samples. METHODS: A total of 192 patients with diagnoses of alcohol-related disorders (n = 45), schizophrenic disorders (n = 52), affective disorders (n = 54), and personality disorders (n = 41) completed a 42-item self-rating scale (Traumatic Antecedents Questionnaire, TAQ). The TAQ assesses personal positive experiences (competence and safety) and negative experiences (neglect, separation, secrets, emotional, physical and sexual abuse, trauma witnessing, other traumas, and alcohol and drugs abuse) during four developmental periods, beginning from early childhood to adulthood. Patients were recruited from four Psychiatric hospitals in Germany, Switzerland, and Romania; 63 subjects without any history of mental illness served as controls. RESULTS: The amount of positive experiences did not differ significantly among groups, except for safety scores that were lower in patients with personality disorders as compared to the other groups. On the other side, negative experiences appeared more frequently in patients than in controls. Emotional neglect and abuse were reported in patients more frequently than physical and sexual abuse, with negative experiences encountered more often in late childhood and adolescence than in early childhood. The patients with alcohol-related and personality disorders reported more negative events than the ones with schizophrenic and affective disorders. CONCLUSIONS: The present findings add evidence to the relationship between retrospectively reported childhood experiences and psychiatric diagnoses, and emphasize the fact that a) emotional neglect and abuse are the most prominent negative experiences, b) adolescence is a more 'sensitive' period for negative experiences as compared to early childhood, and c) a high amount of reported emotional and physical abuse occurs in patients with alcohol-related and personality disorders respectively
Schizophrenia and psychotic symptoms in families of two American Indian tribes
Abstract Background The risk of schizophrenia is thought to be higher in population isolates that have recently been exposed to major and accelerated cultural change, accompanied by ensuing socio-environmental stressors/triggers, than in dominant, mainstream societies. We investigated the prevalence and phenomenology of schizophrenia in 329 females and 253 males of a Southwestern American Indian tribe, and in 194 females and 137 males of a Plains American Indian tribe. These tribal groups were evaluated as part of a broader program of gene-environment investigations of alcoholism and other psychiatric disorders. Methods Semi-structured psychiatric interviews were conducted to allow diagnoses utilizing standardized psychiatric diagnostic criteria, and to limit cultural biases. Study participants were recruited from the community on the basis of membership in pedigrees, and not by convenience. After independent raters evaluated the interviews blindly, DSM-III-R diagnoses were assigned by a consensus of experts well-versed in the local cultures. Results Five of the 582 Southwestern American Indian respondents (prevalence = 8.6 per 1000), and one of the 331 interviewed Plains American Indians (prevalence = 3.02 per 1000) had a lifetime diagnosis of schizophrenia. The lifetime prevalence rates of schizophrenia within these two distinct American Indian tribal groups is consistent with lifetime expectancy rates reported for the general United States population and most isolate and homogeneous populations for which prevalence rates of schizophrenia are available. While we were unable to factor in the potential modifying effect that mortality rates of schizophrenia-suffering tribal members may have had on the overall tribal rates, the incidence of schizophrenia among the living was well within the normative range. Conclusion The occurrence of schizophrenia among members of these two tribal population groups is consistent with prevalence rates reported for population isolates and in the general population. Vulnerabilities to early onset alcohol and drug use disorders do not lend convincing support to a diathesis-stressor model with these stressors, commonly reported with these tribes. Nearly one-fifth of the respondents reported experiencing psychotic-like symptoms, reaffirming the need to examine sociocultural factors actively before making positive diagnoses of psychosis or schizophrenia.</p

Hallucinatory experiences and onset of psychotic disorder: evidence that the risk is mediated by delusion formation
Item does not contain fulltextTo examine the hypothesis that the risk for onset of psychotic disorder in individuals with self-reported hallucinatory experiences (HE) would be higher in those who developed delusional ideation (DE) than in those who did not. Method:
A population sample of 4673 individuals were interviewed with the Composite International Diagnostic Interview at baseline and 1 and 3 years later. At year 3, clinical re-interview took place to identify onset of psychotic disorder. Results:
Given the presence of HEs at baseline, the increase in risk of having the psychosis outcome at year 3 was much higher in those with DE at year 1 than in those without DE (risk difference between individuals with and without DE: 18.72%, 95% CI: 2.22–35.23, 2 = 4.94, df = 1, P = 0.026). Conclusion:
The results are in line with current psychological theories stating that clinical outcome of psychosis-like experiences is related to the development of secondary beliefs and appraisals
Psychotic experiences in people who have been sexually assaulted
Objective In recent years, there has been a call for greater awareness of the relationship between trauma and psychosis, and several studies involving patients with psychotic disorders have found a link between traumatic life experience and the development of psychosis. However, little research has examined psychotic experiences in a traumatised population. Method This study investigated psychotic experiences in a sample of 40 survivors of sexual assault (SA) compared to a control group without a history of sexual assault (measured using a self-report questionnaire) and examined the psychological factors that may contribute to the development of psychotic experiences in sexually traumatised individuals. In particular, the role of dissociation and cognitive factors such as post-traumatic cognitions were explored. Results Of the 26 sexually assaulted participants that were interviewed, 46% reported auditory hallucinations and 46% reported visual hallucinations. A significantly higher rate of psychotic phenomena (delusional ideation and predisposition to hallucinations) was found in the sexually assaulted group compared to the control group. Severity of SA trauma was significantly associated with severity of PTSD and psychotic symptomatology. Dissociation was strongly associated with all measures of psychotic phenomena and negative cognitions about the self and the world were associated with predisposition to hallucinations and delusional ideation. Regression analyses revealed that after controlling for the severity of SA trauma, dissociation and negative beliefs about the self significantly predicted delusional distress, and dissociation significantly predicted predisposition to visual hallucinations. Conclusions These exploratory findings support the idea that psychotic phenomena may be caused by traumatic life experiences and highlight the need for further research. The implications of these results for research and clinical practice are discussed
Dissociação e transtornos dissociativos: modelos teóricos Dissociation and dissociative disorders: theoretical models
A compreensão da experiência dissociativa e das origens dos transtornos dissociativos é difÃcil devido à complexidade da questão. As contradições da classificação são decorrentes das dificuldades de se construir uma teoria da mente abrangente que unifique neurobiologia e psicodinâmica. Os autores discutem as bases conceituais da dissociação com ênfase na integração entre neurobiologia e fenomenologia. O papel do aprendizado é amplamente discutido, assim como as teorias atuais de neodissociação, trauma e sociocognitivismo para os transtornos dissociativos.<br>It is challenging to understand the dissociative experiences and the origins of dissociative disorders. Contradictions of classification are due to the intrinsic difficulties to build up a theory of the mind that unifies neurobiology and psychodynamics. The authors discuss the conceptual basis of dissociation, with emphasis on the integration of neurobiology and phenomenology. The role of learning is discussed as well as the neodissociative, trauma, and sociocognitive theories for dissociative disorders
