What do we really know about witness preparation?

Witnesses often meet with an attorney or witness preparation specialist before trial to review, discuss, and sometimes modify the substance and delivery of their anticipated testimony. This process is commonly referred to as witness preparation. During witness preparation, witnesses are taught to use effective testimony delivery skills (e.g., verbal and nonverbal communication skills) so that they will be perceived as being credible and persuasive in the courtroom. Although social scientists know much about communication skills, credibility, and persuasion, few published studies have attempted to determine whether or not these factors can be modified through witness preparation training. The present article reviews the psychological literature pertaining to witness preparation and makes recommendations for needed witness preparation research.     

Weight suppression as a predictor of weight gain and response to intensive behavioral treatment in patients with anorexia nervosa

Previous studies have documented that weight suppression (a person's highest adult weight minus current weight) predicts weight gain and disordered eating symptoms during treatment of bulimia spectrum disorders, but no research has examined weight suppression in individuals with anorexia nervosa (AN). Thus, this study sought to characterize weight suppression in a large sample of patients with AN (N = 185), and to evaluate whether weight suppression at admission for intensive behavioral treatment predicts weight gain and clinical outcomes at discharge. Weight suppression varied from 0 kg to 78 kg (M [SD] = 17.1 [10.8] kg) in AN patients. Higher levels of weight suppression predicted greater total weight gain, a faster rate of weight gain, and bulimic symptoms during intensive treatment even after controlling for body mass index on admission, length and type of intensive treatment received, restricting versus binge-eating/purging AN subtype, and other predictors of study outcomes. These findings converge with previous research documenting the clinical significance of weight suppression in the treatment of eating disorders. Future work is needed to replicate the current findings, and examine whether weight suppression predicts the course of AN following discharge from intensive treatment.     

The Foundations of Capability Theory: Comparing Nussbaum and Gewirth

This paper is written from a perspective that is sympathetic to the basic idea of the capability approach. Our aim is to compare Martha Nussbaum’s capability theory of justice with Alan Gewirth’s moral theory, on two points: the selection and the justification of a list of central capabilities. On both counts, we contend that Nussbaum’s theory suffers from flaws that Gewirth’s theory may help to remedy. First, we argue that her notion of a (dignified) human life cannot fulfill the role of a normative criterion that Nussbaum wants it to play in selecting capabilities for her list. Second, we question whether Nussbaum’s method of justification is adequate, discussing both her earlier self-validating argumentative strategy and her more recent adherence to the device of an overlapping consensus. We conclude that both strategies fail to provide the capabilities theory with the firm foundation it requires. Next, we turn to Gewirth’s normative theory and discuss how it can repair these flaws. We show how his theory starts from a fundamental moral principle according to which all agents have rights to the protection of the necessary preconditions of their agency. Gewirth’s justification of this principle is then presented, using a version of a transcendental argument. Finally, we explicitly compare Nussbaum and Gewirth and briefly demonstrate what it would mean for Nussbaum to incorporate Gewirthian elements into her capabilities theory of justice.     

A Cognitive-Behavioral-Based Workshop Intervention for Maladaptive Perfectionism

Maladaptive perfectionism (MP) can have adverse consequences for mental and physical health and can interfere with treatment success for various conditions. Theoretical conceptualizations of MP largely surround overly rigid and self-critical thinking as well as excessively high standards. Treatment for MP thus often focuses on these cognitive aspects and has been successful, albeit lengthy. The present study evaluated a brief cognitive-behavioral workshop for those with high, moderate, and low MP, which was defined as a composite of perfectionism subscales that included concern over mistakes, doubting of actions, parental criticism, parental expectations, and discrepancy. Workshop components focused on psychoeducation about MP, setting high standards, fearing mistakes and doubting oneself, and preventing distress and maintaining gains. Ratings of MP as well as anxiety, depression, and distress were significantly lower from pre-treatment across post-treatment and 3-week and 3-month follow-up assessments for those with high and moderate MP. Participants with low MP showed no significant change over time, as expected. The workshop thus provided a useful, brief, and cost-effective intervention for MP and related distress. Clinical implications are discussed, including routine assessment of MP in clinical practice, intervention for MP early in the clinical process, specific focus on self-criticism and setting high standards, and implementation in university counseling centers. Recommendations for future research are also discussed, including dismantling of workshop components, identifying treatment mechanisms, expanding to clinical populations, evaluating more diverse samples, and understanding the possible preventative aspects of a workshop approach.
