Self-efficacy and empowerment as outcomes of self-stigmatizing and coping in schizophrenia

The concept of internalized stigma or self-stigma is central to the understanding of the psychological harm caused by stigma. In this study, we aim to demonstrate how the evaluative dimension of self-concept (self-efficacy and empowerment) mediates the psychological effects of self-stigmatizing and coping with stigma. As important examples of psychological effects, depression and quality of life were focussed on. In 172 outpatients with DSM-IV schizophrenia, measures of self-stigma and devaluation, coping with stigma, self-efficacy, empowerment, quality of life and depression were assessed. It was hypothesized that withdrawal and secrecy as important coping strategies yielded to higher levels of anticipatory anxiety of future stigmatizing. Higher levels of perceived discrimination and devaluation were hypothesised to undermine self-efficacy and illness-related empowerment. Lowering of empowerment was supposed to enhance depression and reduce quality of life. This hypothesis was tested by Structural Equation Modeling as a method of data analysis. The results supported the hypothesized model; i.e., 46% of depression and 58% of quality of life reduction could be explained by eroded empowerment. Moreover, 51% of the empowerment reduction was explained by reduction in self-efficacy at a more general level by dysfunctional coping and higher levels of anticipated stigma. Taken together, our data suggest an avoidant coping style as a risk factor for anticipatory stigma, which erodes self-efficacy and empowerment. These data have implications for cognitive behavioral approaches, which should focus on anticipated stigma to improve recovery in schizophrenia.

Evidence for a curvilinear relationship between posttraumatic growth and posttrauma depression and PTSD in assault survivors.

Two studies of assault survivors (Ns = 180, 70) examined associations between posttraumatic growth (PTG) and posttrauma psychopathology. Both studies found significant curvilinear associations between PTG and posttraumatic stress disorder, whereas only Study 1 found a curvilinear association between PTG and depression symptom severity. Survivors with no or high growth levels reported fewer symptoms than those who reported moderate growth. Study 1 also investigated potential PTG predictors. Non-Caucasian ethnicity, religiousness, peritraumatic fear, shame, and ruminative thinking style, assessed at 2 weeks, predicted growth at 6 months. Posttraumatic growth may thus be most relevant in trauma survivors who attach enduring significance to the trauma for their lives and show initial distress. Moderate levels of PTG do not seem to ameliorate posttrauma psychopathology.

Reduced Autobiographical Memory Specificity Predicts Depression and Posttraumatic Stress Disorder After Recent Trauma

In this prospective longitudinal study, the authors examined the relationship between reduced specificity in autobiographical memory retrieval and the development of depression, posttraumatic stress disorder (PTSD), and specific phobia after injury in an assault. Assault survivors (N = 203) completed the Autobiographical Memory Test (J. M. G. Williams & K. Broadbent, 1986) at 2 weeks after the trauma as well as structured clinical interviews at 2 weeks and 6 months. Participants with acute stress disorder or major depression at 2 weeks, but not those with phobia, retrieved fewer specific autobiographical memories than those without the respective disorder. Reduced memory specificity at 2 weeks also predicted subsequent PTSD and major depression at 6 months over and above what could be predicted from initial diagnoses and symptom severity. Moderator analyses showed that low memory specificity predicted later depression in participants with prior episodes of major depression but not in those without prior depression. Mediation analyses suggested that rumination partly mediated and perceived permanent change fully mediated the effects of low memory specificity on posttrauma psychopathology at follow-up.

Early predictors of chronic post-traumatic stress disorder in assault survivors.

Background Some studies suggest that early psychological treatment is effective in preventing chronic post-traumatic stress disorder (PTSD), but it is as yet unclear how best to identify trauma survivors who need such intervention. This prospective longitudinal study investigated the prognostic validity of acute stress disorder (ASD), of variables derived from a meta-analysis of risk factors for PTSD, and of candidate cognitive and biological variables in predicting chronic PTSD following assault. Method Assault survivors who had been treated for their injuries at a metropolitan Accident and Emergency (A&E) Department were assessed with structured clinical interviews to establish diagnoses of ASD at 2 weeks (n=222) and PTSD at 6 months (n=205) after the assault. Candidate predictors were assessed at 2 weeks. Results Most predictors significantly predicted PTSD status at follow-up. Multivariate logistic regressions showed that a set of four theory-derived cognitive variables predicted PTSD best (Nagelkerke R2=0·50), followed by the variables from the meta-analysis (Nagelkerke R2=0·37) and ASD (Nagelkerke R2=0·25). When all predictors were considered simultaneously, mental defeat, rumination and prior problems with anxiety or depression were chosen as the best combination of predictors (Nagelkerke R2=0·47). Conclusion Questionnaires measuring mental defeat, rumination and pre-trauma psychological problems may help to identify assault survivors at risk of chronic PTSD.

Cognitive Change Predicts Symptom Reduction With Cognitive Therapy for Posttraumatic Stress Disorder

Objective: There is a growing body of evidence for the effectiveness of trauma-focused cognitive behavior therapy (TF-CBT) for posttraumatic stress disorder (PTSD), but few studies to date have investigated the mechanisms by which TF-CBT leads to therapeutic change. Models of PTSD suggest that a core treatment mechanism is the change in dysfunctional appraisals of the trauma and its aftermath. If this is the case, then changes in appraisals should predict a change in symptoms. The present study investigated whether cognitive change precedes symptom change in Cognitive Therapy for PTSD, a version of TF-CBT. Method: The study analyzed weekly cognitive and symptom measures from 268 PTSD patients who received a course of Cognitive Therapy for PTSD, using bivariate latent growth modeling. Results: Results showed that (a) dysfunctional trauma-related appraisals and PTSD symptoms both decreased significantly over the course of treatment, (b) changes in appraisals and symptoms were correlated, and (c) weekly change in appraisals significantly predicted subsequent reduction in symptom scores (both corrected for the general decrease over the course of therapy). Changes in PTSD symptom severity did not predict subsequent changes in appraisals. Conclusions: The study provided preliminary evidence for the temporal precedence of a reduction in negative trauma-related appraisals in symptom reduction during trauma-focused CBT for PTSD. This supports the role of change in appraisals as an active therapeutic mechanism.

Efficacy of Coming Out Proud to reduce stigma’s impact among people with mental illness: pilot randomised controlled trial

BACKGROUND Facing frequent stigma and discrimination, many people with mental illness have to choose between secrecy and disclosure in different settings. Coming Out Proud (COP), a 3-week peer-led group intervention, offers support in this domain in order to reduce stigmas negative impact. AIMS To examine COPs efficacy to reduce negative stigma-related outcomes and to promote adaptive coping styles (Current Controlled Trials number: ISRCTN43516734). METHOD In a pilot randomised controlled trial, 100 participants with mental illness were assigned to COP or a treatment-as-usual control condition. Outcomes included self-stigma, empowerment, stigma stress, secrecy and perceived benefits of disclosure. RESULTS Intention-to-treat analyses found no effect of COP on self-stigma or empowerment, but positive effects on stigma stress, disclosure-related distress, secrecy and perceived benefits of disclosure. Some effects diminished during the 3-week follow-up period. CONCLUSIONS Coming Out Proud has immediate positive effects on disclosure- and stigma stress-related variables and may thus alleviate stigmas negative impact.

Sleep enhances exposure therapy

BACKGROUND Sleep benefits memory consolidation. Here, we tested the beneficial effect of sleep on memory consolidation following exposure psychotherapy of phobic anxiety. METHOD A total of 40 individuals afflicted with spider phobia according to DSM-IV underwent a one-session virtual reality exposure treatment and either slept for 90 min or stayed awake afterwards. RESULTS Sleep following exposure therapy compared with wakefulness led to better reductions in self-reported fear (p = 0.045, d = 0.47) and catastrophic spider-related cognitions (p = 0.026, d = 0.53) during approaching a live spider, both tested after 1 week. Both reductions were associated with greater percentages of stage 2 sleep. CONCLUSIONS Our results indicate that sleep following successful psychotherapy, such as exposure therapy, improves therapeutic effectiveness, possibly by strengthening new non-fearful memory traces established during therapy. These findings offer an important non-invasive alternative to recent attempts to facilitate therapeutic memory extinction and consolidation processes with pharmacological or behavioral interventions.

Screening for posttraumatic stress disorder: What combination of symptoms predicts best?

Several symptom screening instruments have been developed to identify trauma survivors at risk for chronic posttraumatic stress disorder, but few of these have been thoroughly evaluated to date. In this study, a range of symptom combination scoring rules derived from the literature were applied to the Posttraumatic Diagnostic Scale and evaluated in 4 different samples of trauma survivors (total N = 522) regarding their power to identify people with posttraumatic stress disorder. Results were replicated in a fifth sample (N = 253). Most scoring rules showed lower diagnostic efficiencies than in the original reports. The most stable results were obtained for cutoffs on the Posttraumatic Diagnostic Scale total scale and a new subset of 8 items. The results underscore the need to cross-validate findings before using screening instruments for clinical applications.

Are Trauma Memories Disjointed from other Autobiographical Memories in Posttraumatic Stress Disorder? An Experimental Investigation.

This study tested the hypothesis that trauma memories are disjointed from other autobiographical material in posttraumatic stress disorder (PTSD). Assault survivors with (n = 25) and without PTSD (n = 49) completed an autobiographical memory retrieval task during script-driven imagery of (a) the assault and (b) an unrelated negative event. When listening to a taped imagery script of the worst moment of their assault, survivors with PTSD took longer to retrieve unrelated non-traumatic autobiographical information than those without PTSD, but not when listening to a taped script of the worst moment of another negative life event. The groups also did not differ in general retrieval latencies, neither at baseline nor after the imagery tasks. The findings are in line with suggestions that traumatic memories are less integrated with other autobiographical information in trauma survivors with PTSD than in those without PTSD.

Investigating cognitive pathways to psychopathology: Predicting depression and posttraumatic stress disorder from early responses after assault

Depression and posttraumatic stress disorder (PTSD) are common after trauma, but it remains unclear what factors determine which disorder a trauma survivor will develop. A prospective longitudinal study of 222 assault survivors assessed candidate predictors derived from cognitive models of depression and PTSD at 2 weeks posttrauma (N = 222), and depression and PTSD symptom severities (N = 183, 82%) and diagnoses at 6 months (N = 205, 92%). Structural equation modeling showed that the depression and PTSD models predicted both depression and PTSD symptom severity, but that the disorder-specific models predicted the respective outcome best (43% for depression, 59% for PTSD symptom severity). Maintaining cognitive variables (hopelessness and self-devaluative thoughts in depression; cognitive responses to intrusive memories and persistent dissociation in PTSD) showed the clearest specific relationships with outcome. Model-derived variables predicted depression and PTSD diagnoses at 6 months over and above what could be predicted from initial diagnoses. Results support the role of cognitive factors in the development of depression and PTSD after trauma, and provide preliminary evidence for some specificity in maintaining cognitive mechanisms.
