Hypnotic susceptibility, interference, and alternation frequency to the Necker cube illusion

Two experiments (N = 60) were conducted to determine the effects of hypnotic susceptibility and interference on frequency of Necker cube apparent reversals (ARs). Interference was induced in Experiment 1 by having subjects respond to orally administered double-digit arithmetic (addition) problems while observing the Necker cube. In Experiment 2, counting backward by 3s served as interference. In both experiments, interference reduced ARs. Hypnotic susceptibility level also influenced ARs, with those scoring high on this attribute reporting more ARs than those scoring low. Attentional factors may have played a major role in producing the reported results.     

Body image disturbance in patients with borderline personality disorder: Impact of eating disorders and perceived childhood sexual abuse

Body image disturbances occur in women with borderline personality disorder (BPD). Systematic research on these characteristics in well-defined BPD groups is lacking. It is unknown, if the disturbances are related to eating disorders and childhood sexual abuse (CSA), which frequently co-occur in patients with BPD. In the present study, cognitive-affective and behavioral components of body image for 89 female patients with BPD (49 with lifetime eating disorders) and 41 healthy participants were assessed via Body Image Avoidance Questionnaire (BIAQ) and Multidimensional Body-Self Relations Questionnaire (MBSRQ). Within the BPD group, 43 patients reported a history of CSA. Compared to healthy controls, BPD patients reported significantly more negative scores in the BIAQ and the MBSRQ. Both a history of CSA and a comorbid eating disorder were independently associated with an even more negative body image. Results suggest a disturbance of cognitive-affective and behavioral components of body image in female BPD patients.     

Self-regulatory efficacy and activity: Examining gradations of challenge

Objectives

This study examined different scheduling demands as a moderator of the self-regulatory efficacy (SRE)/physical activity relationship.

Design

A prospective design was used.

Method

Adolescents (N = 275) reported SRE and activity during times that reflected high and low scheduling demands.

Results

When scheduling demands were high, SRE predicted individual activity behavior (p < .001). During a period that reflected lower scheduling demands, however, SRE did not predict physical activity behavior (p = .25).

Conclusions

These findings support the idea that the level of challenge (demands) may be an important factor to consider when examining the SRE/activity behavior relationship.     

Validation of the German Version of the Sexual Self-Esteem Inventory for Women and its Application in a Sample of Sexually and Physically Abused Women

Results regarding the association between global self-esteem and sexual behavior suggest the importance of a domain-specific construct—so-called sexual self-esteem (SSE). Prior studies suggested that SSE is malleable and found a negative impact of sexual abuse on SSE. In the present study, the German translation of the Sexual Self-Esteem Inventory-Short Form (SSEI-SF) by Zeanah and Schwarz (1996) was validated via an online survey with 557 women and then investigated in a clinical sample of women suffering from PTSD following sexual and physical abuse compared with healthy controls (n = 130). We examined differences in SSE depending on the type of abuse. Confirmatory factor analysis revealed adequate model fit, with acceptable-to-excellent reliability (α = .78–.94) and sound convergent and discriminant validity. As expected, SSEI-SF scores were significantly lower in the clinical sample than those in the healthy control group. Within the clinical sample, there were no significant differences in SSE between clients who had experienced sexual abuse and those who had experienced physical abuse, but a history of sexual abuse was significantly linked to lower SSE and SSE was related to both sexual behavior and sexual satisfaction. In conclusion, our study supports the validity and applicability of the German version of the SSEI-SF. Results regarding the differences in SSE between survivors of abuse and healthy controls contribute to the further understanding of female sexuality and have implications for treatment.     

Using efficacy information to manipulate proxy efficacy in novice exercisers

ObjectivesTo examine whether proxy efficacy could be increased through an intervention targeting the four sources of efficacy using a written message.DesignPhase 1 (N = 33) tested the stimulus materials to ensure that the intervention message contained significantly more sources of efficacy than the controls. Phase 2 (N = 86) was an intervention assessing the effectiveness of the stimulus materials in increasing proxy efficacy.MethodIn Phase 1, female novice exercisers were randomly assigned to read either an attention control (AC) or proxy efficacy-enhancing (PEE) message about an exercise class leader. Participants completed manipulation checks assessing content, readability, and inclusion of the sources of efficacy. In Phase 2, participants were randomly assigned to AC or PEE groups and read the stimulus materials tested in Phase 1. In order to establish baseline efficacy, all participants read an AC message at Time 1. At Time 2 one week later, the PEE group read the PEE message while the AC group read a second AC message. Participants' proxy efficacy was assessed at both time points in Phase 2.ResultsIn Phase 1, results revealed that the participants who read the PEE message agreed that their stimulus material contained significantly more efficacy-enhancing information than did participants who read the AC messages. In Phase 2, MANCOVA revealed that, after controlling for Time 1 proxy efficacy, the PEE group had significantly greater proxy efficacy at Time 2 than the AC group.ConclusionsResults suggest that proxy efficacy can be increased through targeted written messages.     

The effects of cross-fostering on inherent sensorimotor gating deficits exhibited by Brattleboro rats

Prepulse inhibition (PPI) of the startle reflex is an operational measure of sensorimotor gating, a process critical to normal cognitive function. Researchers (D. Feifel & K. Priebe, 2001) have identified PPI deficits in the Brattleboro rat, a genetically vasopressin-deficient strain that is derived from the Long Evans rat. The absence of vasopressin, a neuropeptide involved in affiliative behaviors, may adversely affect the rearing of offspring by Brattleboro dams, perhaps accounting for their attenuated PPI. Cross-fostering of Long Evans and Brattleboro pups did not alter the PPI deficits in Brattleboro rats. However, the magnitude and habituation of the startle response, which normally differs between Brattleboro and Long Evans rats, was not different in cross-fostered rats. The authors' results indicated that abnormal rearing by Brattleboro dams may contribute to the startle magnitude and habituation abnormalities in Brattleboro Rats but not to their PPI deficits, suggesting that their sensorimotor gating deficits result from their genetic deviation from Long Evans rats.     

The association of religiosity,spirituality, and ethnic background with ego-pathology in acute schizophrenia

Studies have highlighted the impact of ego-consciousness, religiosity and spirituality on psychotic symptoms, although so far no study has investigated if and how these factors may be interrelated. In this exploratory cross-sectional study, involving 42 patients with a diagnosis of acute paranoid schizophrenia (DSM-IV), we assessed religiosity (Religious Orientation Test) spirituality (Spiritual Transcendence Scale) and ego-pathology (Ego Pathology Inventory) and analysed any relationship with these and psychopathological symptoms (Positive and Negative Symptom Scale). The subjects were divided into four ethnic groups (Caucasian, Afro-Caribbean, African, and Asian) and a structured, qualitative interview on religious needs and self-concepts was also conducted. Using a multivariate analysis, we found statistically significant negative associations between the scores on ego and common pathology and religiosity and spirituality as covariates. This was seen across all ethnic groups. The findings are discussed in respect of the potential clinical importance of ethnic, religious and spiritual factors for assessment and management of patients with schizophrenia.     

Personality factors and posttraumatic stress: associations in civilians one year after air attacks

There is an ongoing debate on which risk factors for developing posttraumatic stress symptoms are more important--personality traits reflecting vulnerability, previous stressful experiences or characteristics of the traumatic event. In this study, posttraumatic stress symptoms and their relationship with personality traits, previous stressful experiences and exposure to stressful events during air attacks in Yugoslavia were investigated. The Millon Clinical Multiaxial Inventory (MCMI; Millon, 1983), Impact of Events Scale (IES; Horowitz, Wilner, & Alvarez, 1979), Life Stressor Checklist Revised (LSCL-R; Wolfe & Kimerling, 1997), and List of Stressors were administered to a homogeneous group of medical students 1 year after the attacks. In multiple regression analyses, compulsive and passive-aggressive personality traits and a higher level of exposure to stressors during air attacks independently predicted the degree of intrusion symptoms. Avoidance symptoms were predicted by avoidant personality traits and a higher exposure to stressors both previously in life and during the attacks. In the next step, we tested in analyses of variance whether personality traits, previous stressful experiences, and stressful events during attacks as independent variables interact in predicting intrusion and avoidance symptoms. For this, students were clustered into three groups depending on their predominant personality traits. In addition to direct predictive effects, there were significant interaction effects in predicting both intrusion and avoidance. The findings suggest that each of the tested factors, i.e., personality traits, previous stressful experiences, and exposure to traumatic events may have an independent and direct influence on developing posttraumatic stress. However, the effect of these factors cannot just be added up. Rather, the factors interact in their impact on posttraumatic stress symptoms. Bigger samples and longitudinal designs will be required to understand precisely how different personality traits influence response to stressful events.     

Perceived Rejection in Personality Psychopathology: The Role of Attachment and Gender

Prior research suggests that individuals with higher rates of personality psychopathology are more likely to endorse insecure attachment patterns which can lead to stronger reactions towards perceived rejection. This study investigated how attachment style and gender moderate the strength of the association between personality psychopathology and reactions to perceived rejection. To examine the role of attachment and gender in the relationship between personality psychopathology and reactions to perceived rejection, an undergraduate sample of 150 students, as well as an Amazon Mechanical Turk (MTurk) sample of 278 individuals, completed various personality and attachment self-report measures and watched video clips addressing rejection from parents, peers, and romantic partners. Multivariate analyses of variance and moderation effects suggested that attachment patterns inconsistently moderate maladaptive reactions to rejection, and that gender moderates the relationship between personality psychopathology and externalizing reactions to rejection. Specifically, men with more pronounced Antagonism and Psychoticism trait facets demonstrated a higher propensity towards externalizing and internalizing reactions to rejection than women in these domains.
