Toward the clarification of the construct of depersonalization and its association with affective and cognitive dysfunctions.

Little consensus or systematic research exists regarding the symptoms that constitute depersonalization and its association with affective and perceptual dysfunctions. A scale was constructed to measure depersonalization experiences reported in the literature and four items representing psychotic symptoms. Five factors representing different types of depersonalization emerged: Inauthenticity, Self-Negation, Self-Objectification, Derealization, and Body Detachment. Based on the factors, scales were constructed; these scales have internal consistency ranging from .78 to .84. Each of these factor scales was factorially distinguishable from psychosis and correlated between .48 and .58 with the Jackson and Messick (1972) Feelings of Unreality Scale, suggesting divergent and convergent validity. Inauthenticity, the most frequent and pervasive form of depersonalization experience, was best predicted by a cognitive style featuring intense, critical examination of self and others. In contrast, Self-Objectification was best predicted by thought disorganization and perceptual distortion and was experienced somewhat infrequently by relatively few subjects. All forms of depersonalization were associated with depression, except Inauthenticity.     

The impact of dissociation and depression on the efficacy of prolonged exposure treatment for PTSD

This study investigates the impact of dissociative phenomena and depression on the efficacy of prolonged exposure treatment in 71 patients with posttraumatic stress disorder (PTSD). Diagnoses, comorbidity, pretreatment depressive symptoms, PTSD symptom severity, and dissociative phenomena (trait dissociation, numbing, and depersonalization) were assessed at pretreatment using semi-structured interviews and questionnaires. In a pretreatment behavioral exposure test, patients were imaginally exposed to (part of) their trauma memory for 9 min, during which subjective fear was assessed. At posttreatment and 6 months follow-up PTSD, depressive and dissociative symptoms were again assessed in the completers (n = 60). Pretreatment levels of dissociative and depressive symptoms were similar in dropouts and completers and none of the dissociative phenomena nor depression predicted improvement. Against expectations, dissociative phenomena and depression were associated with enhanced rather than impeded fear activation during the behavioral exposure test. However, these effects disappeared after controlling for initial PTSD severity. Hence, rather than supporting contraindication, the current results imply that patients presenting with even severe dissociative or depressive symptoms may profit similarly from exposure treatment as do patients with minimal dissociative or depressive symptoms.

Analysis of the multidimensionality of hallucination-like experiences in clinical and nonclinical Spanish samples and their relation to clinical symptoms: implications for the model of continuity

Numerous studies have found that hallucinatory experiences occur in the general population. But to date, few studies have been conducted to compare clinical and nonclinical groups across a broad array of clinical symptoms that may co-occur with hallucinations. Likewise, hallucination-like experiences are measured as a multidimensional construct, with clinical and subclinical components related to vivid daydreams, intrusive thoughts, perceptual disturbance, and clinical hallucinatory experiences. Nevertheless, these individual subcomponents have not been examined across a broad spectrum of clinically disordered and nonclinical groups. The goal of the present study was to analyze the differences and similarities in the distribution of responses to hallucination-like experience in clinical and nonclinical populations and to determine the relation of these hallucination-like experiences with various clinical symptoms. These groups included patients with schizophrenia, non-psychotic clinically disordered patients, and a group of individuals with no psychiatric diagnoses. The results revealed that hallucination-like experiences are related to various clinical symptoms across diverse groups of individuals. Regression analysis found that the Psychoticism dimension of the Symptom Check List (SCL-90-R) was the most important predictor of hallucination-like experiences. Additionally, increased auditory and visual hallucination was the only subcomponent that differentiated schizophrenic patients from other groups. This distribution of responses in the dimensions of hallucination-like experiences suggests that not all the dimensions are characteristic of people hearing voices. Vivid daydreams, intrusive thoughts, and auditory distortions and visual perceptual distortions may represent a state of general vulnerability that does not denote a specific risk for clinical hallucinations. Overall, these results support the notion that hallucination-like experiences are closer to a quasi-continuum approach and that total scores on these scales explain a state of vulnerability to general perceptual disturbance.     

Positive schizotypal symptoms predict treatment outcome in obsessive-compulsive disorder

Previous research has suggested that the presence of schizotypal personality disorder may represent a risk factor for treatment failure in obsessive-compulsive disorder (OCD). Relying on a dimensional approach, the present study investigated whether the predictive importance of schizotypal personality is shared by all of its features to the same extent or whether it is confined to a subset of symptoms. Fifty-three patients underwent multi-modal cognitive-behavioral therapy with or without adjunctive antidepressive medication. Therapy response was defined as a 35% decline of the Y-BOCS total score. At baseline assessment, patients were asked to fill out the schizotypal personality questionnaire, the perceptual aberration scale and the Beck depression inventory. Stepwise regression analysis and group comparisons conducted with the schizotypal and depression scales revealed that elevated scores in the positive schizotypal scales, especially perceptual aberrations, were highly predictive for treatment failure. Responders to treatment and non-responders did not significantly differ on other variables or on scores in two scales which measured response biases. The study provides evidence that positive schizotypal symptoms are antecendents for treatment failure in OCD. It needs to be evaluated whether these at-risk individuals benefit from additional intervention, such as the adminstration of low-dose atypical neuroleptics and specifically tailored behavorial intervention.     

Psychometric validation of the obsessive belief questionnaire and interpretation of intrusions inventory--Part 2: Factor analyses and testing of a brief version

The Obsessive Belief Questionnaire (OBQ) and the Interpretation of Intrusions Inventory (III) were designed to assess beliefs and appraisals considered critical to the pathogenesis of obsessions. In previous reports we have described the construction and psychometric properties of these measures. In this study a battery of questionnaires assessing anxiety, depression, and obsessive compulsive symptoms was completed by 410 outpatients diagnosed with obsessive compulsive disorder, 105 non-obsessional anxious patients, 87 non-clinical adults from the community, and 291 undergraduate students. Items from 6 theoretically derived subscales of the OBQ were submitted to factor analysis. Three factors emerged reflecting (1) Responsibility and threat estimation, (2) Perfectionism and intolerance for uncertainty, and (3) Importance and control of thoughts. A 44-item version (OBQ-44) composed of high-loading items from the 3 factors showed good internal consistency and criterion-related validity in clinical and non-clinical samples. Subscales showed less overlap than original scales. Factor analysis of the III yielded a single factor, suggesting the total score be used in lieu of the 3 rationally derived subscales. The scales performed well on tests of convergent validity. Discriminant validity was promising; hierarchical regression analyses indicated that the OBQ subscales and III generally predicted OC symptoms after controlling for general distress. A revision of the OBQ, the OBQ-44, is included in the appendix.     

Self-reported attachment, interpersonal aggression, and personality disorder in a prospective community sample of adolescents and adults

Anxious and avoidant attachment were assessed in the Children in the Community (CIC) Study during adolescence and adulthood using self-report scales developed for this prospective study. The convergent and discriminant validity of the new CIC attachment scales were evaluated and their stability was assessed across a 17-year interval. Attachment scales predicted DSM-IV personality disorders in theoretically coherent and clinically meaningful ways, especially when supplemented with a separate measure of interpersonal aggression. Cluster B and C personality disorder symptoms were associated with elevated anxious attachment. Avoidant attachment was positively associated with Cluster A symptoms and inversely associated with Cluster B and C symptoms. Interpersonal aggression was higher in Cluster B symptoms and lower in Cluster C symptoms, thus differentiating between these symptom clusters.

Positive and negative symptoms of schizotypy and the Five-factor model: a domain and facet level analysis

In this study, we investigated the Five-factor model in the concurrent prediction of positive symptom schizotypy as measured by the Magical Ideation (Eckblad & Chapman, 1983) and Perceptual Aberration (Chapman, Chapman, & Raulin, 1978) scales and negative symptom schizotypy as measured by the Physical Anhedonia (Chapman, Chapman, & Raulin, 1976) and Revised Social Anhedonia (Eckblad, Chapman, Chapman, & Mishlove, 1982; Mishlove & Chapman, 1985) scales. Previous studies suggest that these measures reflect the core symptoms found in schizotypal and schizoid personality disorder (Bailey, West, Widiger, & Freiman, 1993). Negative symptoms were significantly predicted by Neuroticism (+), Extraversion (-), Openness (-), and Agreeableness (-) domains of the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992). Additionally, positive symptoms were significantly predicted by Neuroticism (+), Openness (+), and Agreeableness (-). In addition, we examined the validity of lower order traits in de- scribing these symptoms of character pathology. These findings lend further support for the use of domain and facet scales of the NEO-PI-R in the identification of personality pathology.     

Dissociations of the night: individual differences in sleep-related experiences and their relation to dissociation and schizotypy.

The author examined the associations among sleep-related experiences (e.g., hypnagogic hallucinations, nightmares, waking dreams, and lucid dreams), dissociation, schizotypy, and the Big Five personality traits in 2 large student samples. Confirmatory factor analyses indicated that (a) dissociation and schizotypy are strongly correlated-yet distinguishable-constructs, and (b) the differentiation between them can be enhanced by eliminating detachment/depersonalization items from the dissociation scales. A general measure of sleep experiences was substantially correlated with both schizotypy and dissociation (especially the latter) and more weakly related to the Big Five. In contrast, an index of lucid dreaming was weakly related to all of these other scales. These results suggest that measures of dissociation, schizotypy, and sleep-related experiences all define a common domain characterized by unusual cognitions and perceptions.     

Childhood anxiety sensitivity index factors predict unique variance in DSM-IV anxiety disorder symptoms

Anxiety sensitivity (AS) is an established cognitive risk factor for anxiety disorders. In children and adolescents, AS is usually measured with the Childhood Anxiety Sensitivity Index (CASI). Factor analytic studies suggest that the CASI is comprised of 3 lower-order factors pertaining to Physical, Psychological and Social Concerns. There has been little research on the validity of these lower-order factors. We examined the concurrent and incremental validity of the CASI and its lower-order factors in a non-clinical sample of 349 children and adolescents. CASI scores predicted symptoms of DSM-IV anxiety disorder subtypes as measured by the Spence Children's Anxiety Scale (SCAS) after accounting for variance due to State-Trait Anxiety Inventory scores. CASI Physical Concerns scores incrementally predicted scores on each of the SCAS scales, whereas scores on the Social and Psychological Concerns subscales incrementally predicted scores on conceptually related symptom scales (e.g. CASI Social Concerns scores predicted Social Phobia symptoms). Overall, this study demonstrates that there is added value in measuring AS factors in children and adolescents.     

Childhood Anxiety Sensitivity Index Factors Predict Unique Variance in DSM‐IV Anxiety Disorder Symptoms

Anxiety sensitivity (AS) is an established cognitive risk factor for anxiety disorders. In children and adolescents, AS is usually measured with the Childhood Anxiety Sensitivity Index (CASI). Factor analytic studies suggest that the CASI is comprised of 3 lower‐order factors pertaining to Physical, Psychological and Social Concerns. There has been little research on the validity of these lower‐order factors. We examined the concurrent and incremental validity of the CASI and its lower‐order factors in a non‐clinical sample of 349 children and adolescents. CASI scores predicted symptoms of DSM‐IV anxiety disorder subtypes as measured by the Spence Children's Anxiety Scale (SCAS) after accounting for variance due to State‐Trait Anxiety Inventory scores. CASI Physical Concerns scores incrementally predicted scores on each of the SCAS scales, whereas scores on the Social and Psychological Concerns subscales incrementally predicted scores on conceptually related symptom scales (e.g. CASI Social Concerns scores predicted Social Phobia symptoms). Overall, this study demonstrates that there is added value in measuring AS factors in children and adolescents.     

Self-Transformation at the Boundary of Religious Conversion and Psychosis

The relationship between religious conversion, as a form of spiritual emergency, and psychosis is one of the fundamental issues at the meeting point of theology and clinical psychology. In the present study, we assessed 53 individuals referred to a psychiatry center with the initial diagnosis of a psychotic episode by focusing on the clinical diagnosis (psychosis vs. spiritual emergency), subjective experiences (basic symptoms), and neuropsychological functions. Twenty-nine individuals meet the diagnosis of schizophrenia-spectrum disorders, but 24 persons experienced only religious and spiritual problems (religious conversion). Both groups reported similar levels of perplexity (e.g., ambivalence, inability to discriminate between own feelings, and hyperreflectivity) and self-disorder (e.g., depersonalization, impression of a change in one’s mirror image, and experience of discontinuity in own action). Diminished affectivity, disturbed contact, and perceptual/cognitive disorders were pronounced in psychosis, whereas anxiety and depressive symptoms were more severe in people with spiritual and religious problems. These results indicate that perplexity, self-disorder, and emotional turmoil are common features of turbulent religious conversion and psychosis, but a broader emergence of anomalous subjective experiences and cognitive deficits are detectable only in psychosis.

     

Relevance of social categories,depersonalization and group processes: two field tests of self‐categorization theory

Two field studies investigated whether, as predicted by self‐categorization theory (Turner, 1987 ), the relationship between comparative fit of an ingroup‐outgroup categorization and group phenomena is mediated by depersonalization of self‐perception, and moderated by category accessibility. In the first study participants were football fans, and in the second they were employees in an organization. In each study, two experimental conditions were created, whereby the accessibility and salience of the ingroup‐outgroup categorization were varied. New measures of comparative fit and depersonalization were developed, based on meta‐contrast ratios. Outcome variables were ingroup bias (Studies 1 and 2), ingroup entitativity, organizational citizenship behaviours, job satisfaction and turnover intentions (Study 2). Consistent with self‐categorization theory, results showed (a) that comparative fit determined ingroup bias and other criterion variables through the mediating process of depersonalization, and (b) that this process was active only when the category was highly accessible. The moderational role of accessibility concerned the relationship between depersonalization and outcome variables, not the link between fit and depersonalization.

Dimensions of self-serving misrepresentation in forensic assessment

I conducted an exploratory principal components analysis of 15 scales that evaluate a variety of possible self-serving biases using assessment data from 101 general forensic clients. Three distinct factors emerged, representing exaggeration of psychiatric symptoms versus exaggeration of personal adjustment, exaggeration of virtue, and exaggeration of physical health difficulties. Confirmatory factor analysis supported the findings. The surprising fact that none of the scales contained a significant number of items representing the affirmation or exaggeration of positive mental health adjustment precluded the possibility of finding a specific factor in that area. The factor structure was similar to previous results based on personal injury evaluations alone, suggesting that this 3-factor categorization of self-serving misrepresentation has some degree of generality, at least in forensic settings.     

Depressive symptoms predict decline in perceptual speed in older adulthood

Depressive symptoms and cognitive decline are associated in older age, but research is inconsistent about whether one condition influences the development of the other. We examined the directionality of relations between depressive symptoms and perceptual speed using bivariate dual change score models. Assessments of depressive symptoms and perceptual speed were completed by 1,206 nondemented older adults at baseline, and after 2, 8, 11, and 15 years. After controlling for age, education, baseline general cognitive ability, and self-reported health, allowing depressive symptoms to predict subsequent change in perceptual speed provided the best fit. More depressive symptoms predicted subsequently stronger declines in perceptual speed over time lags of 1 year.     

Dimensions in the perception of architecture:II. Measures of exploratory behavior

Four experiments were conducted with 20 slides of buildings representing major architectural styles. The purpose of the experiments was to determine interrelations of verbal and non-verbal measures. The experiments were concerned with: (1) Looking Time, (2) Reward Value, (3) Judgments indicative of Exploratory Tendencies, and (4) Exploratory Choice. The findings were consistent with previous studies in experimental aesthetics. It was concluded that exploratory reactions to the architectural environment may be expressed in at least two types of behavior. First, exploratory behavior was found to be related to perceptual curiosity aroused by a building. Secondly, behavior could be predicted from the hedonic aspects of the building. These two underlying variables were also found to merge frequently.     

Social factors and the psychobiology of depression: relations between life stress and rapid eye movement sleep latency.

We examined psychosocial factors (i.e., life stress) and biological factors (i.e., REM sleep latency) that are hypothesized to be of complementary importance for defining depressive subtypes in a sample of 61 nonpsychotic, endogenous major depressives. Subjects were evaluated on several diagnostic scales for life stress, on electroencephalographic sleep data, and on 2 symptom measures for depression. As predicted, persons with severe stress that occurred shortly before depression onset had essentially normal REM latency values; patients without such stress had reduced REM latency values. Both stress and REM latency were also associated with greater severity of self-reported depressive symptoms. Alternative explanations of these findings are discussed, with particular emphasis on different roles of pre-onset and post-onset stressors.     

The relationship between suppression and subsequent intrusions: the mediating role of peritraumatic dissociation and anxiety

Background and objectives: Although previous studies showed that thought and emotion suppression represent risk factors for intrusions development, the mechanisms that explain these relations were less explored. This study aims to examine the relationships between thought and emotion suppression and the symptoms of intrusion following the exposure to a trauma-related event. Moreover, we explored if these relationships would be mediated by peritraumatic state dissociation and state anxiety.

Design and methods: The trauma film paradigm was used and the participants were students (N?=?148) experimentally exposed to an aversive film to model a traumatic experience. Thought and emotion suppression were measured before the trauma exposure. After exposure, the participants completed scales for measuring state dissociation and state anxiety. Intrusive images and thoughts of the film were recorded in the subsequent week using an intrusion diary.

Results: Thought suppression predicted intrusive thoughts frequency, and this effect was mediated by the peritraumatic anxiety. State anxiety predicted both intrusive images and thoughts, while state dissociation only predicted intrusive images.

Conclusions: Intrusive images and intrusive thoughts are different phenomena and they are predicted by different variables. The practical implications of these results for posttraumatic stress disorder treatment and secondary traumatization are discussed.

Abstract

The relationship between work and home-based stressors in predicting burnout symptoms was examined amongst 120 drug and alcohol service employees. Staff who reported high levels of burnout on the Maslach Burnout Inventory across all three scales of Emotional Exhaustion, Depersonalization and Personal Accomplishment were compared with a sample of low burnout employees. High burnout was associated with younger age, larger agency size, high levels of total work stressors, work overload, and daily hassles and a lower level of peer cohesion. Regression analyses revealed that male gender, younger age, work overload, role ambiguity and daily hassles were significant predictors of Emotional Exhaustion. Younger age was also a significant predictor of Depersonalization. Marked differences were found in the way in which males and females responded to work and non-work stressors and the interaction between these variables. For women, a significant interaction was found between total work stressors and home-based stressors in the prediction of Emotional Exhaustion and a trend in this direction was evident for Depersonalization. Low levels of home problems appeared to protect women from the adverse impact of work stressors. The burnout levels of women were relatively unaffected by work stressors, unless home stressors were also high. The level of daily hassles had a direct effect upon symptoms of Emotional Exhaustion, but did not interact with work stressors in predicting Emotional Exhaustion for women. Burnout levels of male employees on Emotional Exhaustion and Depersonalization scales were strongly linked to the level of work stressors and were not predicted by total home stressors nor the interaction between these variables. Symptoms of Emotional Exhaustion in males were predicted by severity of daily hassles, but this variable did not interact with work stressors in predicting Emotional Exhaustion.
