A systematic review of the evidence base for Schema Therapy

Schema Therapy is becoming an increasingly popular psychological model for working with individuals who have a variety of mental health and personality difficulties. The aim of this review is to look at the current evidence base for Schema Therapy and highlight directions for further research. A systematic search of the literature was conducted up until January 2011. All studies that had clinically tested the efficacy of Schema Therapy as described by Jeffrey Young (1994 and 2003) were considered. These studies underwent detailed quality assessments based on Scottish Intercollegiate Guidelines Network (SIGN-50) culminating in 12 studies being included in the review. The culminative message (both from the popularity of this model and the medium-to-large effect sizes) is of a theory that has already demonstrated clinically effective outcomes in a small number of studies and that would benefit from ongoing research and development with complex client groups. It is imperative that psychological practice be guided by high-quality research that demonstrates efficacious, evidence-based interventions. It is therefore recommended that researchers and clinicians working with Schema Therapy seek to build on these positive outcomes and further demonstrate the clinical effectiveness of this model through ongoing research.     

Wanting a body that's better than average: the effect of manipulated body norms on ideal body size perception

We examined the effect of body norms on ideal and current body size perception. In Study One, female participants were randomly assigned to one of three experimental conditions: (1) a thinner body norm, (2) a heavier body norm, or (3) no body norm. Body norms were manipulated by indicating a bogus "population average," and current and ideal body size perception were subsequently measured using a body silhouettes measure. Women had a thinner ideal body size in the thinner norm condition than in the heavier norm condition. Study Two replicated these results, but in a sample of young men and with regards to muscularity rather than thinness. Men had a more muscular ideal body size in the more muscular norm condition than in the less muscular norm condition. Current body size perception was also influenced by body norms, but only for women and after controlling for BMI.     

Preliminary examination of a couple-based eating disorder prevention program

The purpose of the current study was to investigate a new dissonance-based prevention program that is based on the dual pathway model of eating disorders within the context of an individual's romantic relationship. A total of 209 dating couples participated in a couple-based prevention program or an assessment-only condition and completed measures of body dissatisfaction, thin-ideal internalization, disordered eating, negative affect, and relationship satisfaction at two time points (approximately one week apart) and approximately half of the sample completed 1-month follow-up measures. The prevention program significantly reduced several key risk factors for eating disorders such as environmental pressures to be thin, internalization of the thin and athletic ideals, state body dissatisfaction, and actual-ideal body discrepancy. Initial support was found for the inclusion of couples in eating disorder prevention programs as a successful way of addressing the thin ideal and its detrimental effects for women.     

Action-specific effects underwater

Action-specific effects on perception are apparent in terrestrial environments. For example, targets that require more effort to walk, jump, or throw to look farther away than when the targets require less effort. Here, we examined whether action-specific effects would generalize to an underwater environment. Instead, perception might be geometrically precise, rather than action-specific, in an environment that is novel from an evolutionary perspective. We manipulated ease to swim by giving participants swimming flippers or taking them away. Those who estimated distance while wearing the flippers judged underwater targets to be closer than did participants who had taken them off. In addition, participants with better swimming ability judged the targets to be closer than did those with worse swimming ability. These results suggest perceived distance underwater is a function of the perceiver's ability to swim to the targets.     

Bogus concerns about the false prototype enhancement effect

Two experiments addressed the mechanism responsible for the false prototype effect, the phenomenon in which a prototype gradient can be obtained in the absence of learning. Previous demonstrations of this effect have occurred solely in a single-category paradigm in which transfer patterns are assigned or not to the learning category. We tested the hypothesis that any extraneous variable potentially responsible for this effect, such as compactness varying with pattern distortion (Zaki & Nosofsky, 2004), may be functional in the single-category paradigm but not when multiple categories are available at the time of transfer. In the present study, subjects received a bogus or a real category learning phase, followed by a transfer test that required assignment into 1 or 3 prototype categories. The results showed that a minimal prototype gradient was obtained in the bogus conditions, with performance approaching chance levels when classification into 3 categories was required. In contrast, a substantial prototype gradient effect was found following learning. We conclude that the prototype gradient typically obtained following multiple-category learning is primarily driven by real learning and that the false prototype effect is itself an artifact of the single-category paradigm.     

Considering her circumstances: how ethnicity and cultural relativist arguments affect sexual harassment judgments by undergraduate and community mock jurors

Most research on sexual harassment has involved undergraduate students and European Americans, whose perspectives may not be representative of the broader population. This study investigated whether judgments of a sexual harassment trial vary by plaintiff ethnicity (European American or Latin American), type of sample (undergraduates or community members) and mock juror ethnicity (European American or Latin American). We also tested the effects of a cultural relativist argument about Latin American cultural values influencing the plaintiff. Results indicated that community and Latin American mock jurors rendered more pro-plaintiff verdicts, particularly when the case did not include a cultural relativist argument. Although the cultural relativist argument did not affect undergraduates' judgments, it caused a backlash among community members, leading to more pro-defendant verdicts. Judgments across type of sample and mock juror ethnicity were partially mediated by self-referencing and hostile sexism; affiliation with Latin American culture also predicted judgments of the Latina American plaintiff.     

Watching Aggressive, Attractive, Female Protagonists Shapes Gender Roles for Women Among Male and Female Undergraduate Viewers

The impact of exposure to media representations of aggressive, attractive, female protagonists on audiences?? gender role expectations for women was explored through a laboratory experiment with 122 undergraduates from a large university on the west coast of the United States. Participants viewed a segment of a major Hollywood motion picture that featured a female protagonist who was either highly attractive or less attractive and either highly aggressive or not aggressive. Viewing clips featuring a female protagonist who was both aggressive and stereotypically attractive led to greater endorsement of stereotypically feminine and stereotypically masculine gender role expectations for women. The effect on endorsement of stereotypically masculine expectations was partially mediated by the perception that the protagonist was a good role model for women. Although women endorsed both feminine and masculine gender role expectations for women more strongly than men, the effects of exposure to aggressive, attractive, female protagonists were similar for both male and female participants. Results are discussed in terms of gender stereotype activation and superwoman expectations for women.     

Examining the Psychometric Properties of the Family Accommodation Scale-Parent-Report (FAS-PR)

Growing research has examined parental accommodation among the families of children with obsessive-compulsive disorder (OCD). However, these studies have utilized a parent-report (PR) version of a measure, the Family Accommodation Scale (FAS) that has never received proper psychometric validation. In turn, previously derived subscales have been developed via clinical rather than empirical evidence. This study aims to conduct a comprehensive psychometric analysis of the FAS-PR utilizing data collected from 96 youths with OCD. Exploratory factors analysis was conducted and revealed a 12-item scale yielding two separate, yet related subscales, Avoidance of Triggers (AT) and Involvement in Compulsions (IC). Subsequent analyses revealed good internal consistency and convergent and discriminant validity. These findings suggest that future research should seek to examine factors that may impact various facets to accommodation as well as the role these facets plays in predicting treatment outcome. Limitations are discussed.     

Ironic effects of antiprejudice messages: how motivational interventions can reduce (but also increase) prejudice

Although prejudice-reduction policies and interventions abound, is it possible that some of them result in the precise opposite of their intended effect--an increase in prejudice? We examined this question by exploring the impact of motivation-based prejudice-reduction interventions and assessing whether certain popular practices might in fact increase prejudice. In two experiments, participants received detailed information on, or were primed with, the goal of prejudice reduction; the information and primes either encouraged autonomous motivation to regulate prejudice or emphasized the societal requirement to control prejudice. Ironically, motivating people to reduce prejudice by emphasizing external control produced more explicit and implicit prejudice than did not intervening at all. Conversely, participants in whom autonomous motivation to regulate prejudice was induced displayed less explicit and implicit prejudice compared with no-treatment control participants. We outline strategies for effectively reducing prejudice and discuss the detrimental consequences of enforcing antiprejudice standards.     

Sensitivity to interpersonal treatment in the workplace: Scale development and initial validation

The authors designed the sensitivity to interpersonal treatment (SIT) scale to assess how strongly individuals react to the interpersonal interactions in their workplaces. Questionnaire responses from 563 working undergraduates and 446 working adults provided data for this study. Details on the development of the new scale are provided along with initial evidence for its validity. Results indicated that the SIT is an internally consistent scale composed of two factors: self‐treatment and other‐treatment. Suggestions for future research that will develop a further understanding of SIT in the workplace are discussed.
