Childhood negative experiences and subclinical psychosis in adolescence: a longitudinal general population study

EARLY INTERVENTION IN PSYCHIATRY, Issue 2 2007
Ellen De Loore
Abstract Background:, Accumulating evidence suggests that experiences of trauma and victimization during childhood are associated with an increased risk to develop clinical and subclinical psychosis in adulthood. A recent cross-sectional study showed a significant association between trauma and psychotic experiences in adolescents. The current study aimed to extend these findings by investigating the longitudinal effects of negative life experiences on the risk for subclinical psychotic symptoms 2 years later in an adolescent general community sample. Methods:, Data were derived from the standard health screenings of the Youth Health Care Divisions of the Public Health Services, in the South of the Netherlands. A total of 1129 adolescents filled out a self-report questionnaire at age 13/14 years and 2 years later (15/16 years), assessing psychotic experiences, as well as experiences of being bullied, sexual trauma, and negative life events. Results:, Logistic regression analyses revealed that sexual trauma increased the risk for psychotic symptoms 2 years later. Life events contributed to the risk for psychosis over time and psychosis in turn gave rise to new life events. No significant association with bullying was found after controlling for confounders. Conclusion:, The results provide further evidence for an association between childhood environment and psychosis in the crucial developmental period of early adolescence. Early and later psychological stress, if severe, may impact on the risk for psychosis in adolescence through mechanisms of person,environment interaction and correlation. [source]

Tests of causal linkages between cannabis use and psychotic symptoms

ADDICTION, Issue 3 2005
David M. Fergusson
ABSTRACT Aim To examine possible causal linkages between cannabis use and psychosis using data gathered over the course of a 25-year longitudinal study. Design A 25-year longitudinal study of the health, development and adjustment of a birth cohort of 1265 New Zealand children (635 males, 630 females). Setting The Christchurch Health and Development Study, a general community sample. Participants A total of 1055 participants from the Christchurch Health and Development Study (CHDS) cohort for whom data on cannabis use and psychotic symptoms were available on at least one occasion from 18, 21 and 25 years. Measurements As part of this study, data were gathered on frequency of cannabis use and psychotic symptoms at ages 18, 21 and 25 years. Findings Regression models adjusting for observed and non-observed confounding suggested that daily users of cannabis had rates of psychotic symptoms that were between 1.6 and 1.8 times higher (P < 0.001) than non-users of cannabis. Structural equation modelling suggested that these associations reflected the effects of cannabis use on symptom levels rather than the effects of symptom levels on cannabis use. Conclusions The results of the present study add to a growing body of evidence suggesting that regular cannabis use may increase risks of psychosis. The present study suggests that: (a) the association between cannabis use and psychotic symptoms is unlikely to be due to confounding factors; and (b) the direction of causality is from cannabis use to psychotic symptoms.

Shame as a traumatic memory,

CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 4 2010
Marcela Matos
Abstract Background: This study explores the premise that shame episodes can have the properties of traumatic memories, involving intrusions, flashbacks, strong emotional avoidance, hyper arousal, fragmented states of mind and dissociation. Method: A battery of self-report questionnaires was used to assess shame, shame traumatic memory and depression in 811 participants from general population (481 undergraduate students and 330 subjects from normal population). Results: Results show that early shame experiences do indeed reveal traumatic memory characteristics. Moreover, these experiences are associated with current feelings of internal and external shame in adulthood. We also found that current shame and depression are significantly related. Key to our findings is that those individuals whose shame memories display more traumatic characteristics show more depressive symptoms. A moderator analysis suggested an effect of shame traumatic memory on the relationship between shame and depression. Limitations: The transversal nature of our study design, the use of self-reports questionnaires, the possibility of selective memories in participants' retrospective reports and the use of a general community sample, are some methodological limitations that should be considered in our investigation. Conclusion: Our study presents novel perspectives on the nature of shame and its relation to psychopathology, empirically supporting the proposal that shame memories have traumatic memory characteristics, that not only affect shame in adulthood but also seem to moderate the impact of shame on depression. Therefore, these considerations emphasize the importance of assessing and intervening on shame memories in a therapeutic context.,Copyright © 2009 John Wiley & Sons, Ltd. Key Practitioner Message: Early shame experiences reveal traumatic memory characteristics and are related to current shame and to psychopathology. Individuals whose shame memories have more traumatic characteristics are those who show more depressive symptoms. Shame traumatic memories moderate the relationship between shame and depression, hence to the same shame, individuals who experienced shame as more traumatic are the ones who show more depressive symptoms. Therapy for shame-based problems needs to incorporate strategies to assess and address individuals shame traumatic memories. [source]

Parental Bonding and Adult Attachment Styles in Different Types of Stalker,

JOURNAL OF FORENSIC SCIENCES, Issue 6 2008
Rachel D. MacKenzie D.Psych.
Abstract:, Attachment theory is one of the earliest and most vigorously promoted explanations of the psychological processes that underlie stalking behavior. Insecure attachment has been proposed as impairing the management of relationships, thus increasing the propensity to stalk. The current study explored the parental bonding and adult attachment styles of 122 stalkers referred to a specialist forensic clinic. Stalkers were grouped according to two common classification methods: relationship and motivation. Compared to general community samples, stalkers were more likely to remember their parents as emotionally neglectful and have insecure adult attachment styles, with the degree of divergence varying according to stalker type and mode of classification. In offering support for the theoretical proposition that stalking evolves from pathological attachment, these findings highlight the need to consider attachment in the assessment and management of stalkers. Also emphasized is the importance of taking classification methods into account when interpreting and evaluating stalking research. [source]
