Culturally Motivated Clinician Drift in the Treatment of Eating Disorders: How Clinicians Adopt, Adapt, or Abandon CBT for Latino Clients

Description
Prior research has identified that clinicians in the treatment of eating disorders often do not adhere closely to empirically-supported treatments (EST), and are particularly likely to modify Cognitive-Behavioral therapy (CBT). Several reasons for this phenomenon, dubbed "clinician drift", have been identified, including level of clinician training, education, and type of…

Prior research has identified that clinicians in the treatment of eating disorders often do not adhere closely to empirically-supported treatments (EST), and are particularly likely to modify Cognitive-Behavioral therapy (CBT). Several reasons for this phenomenon, dubbed "clinician drift", have been identified, including level of clinician training, education, and type of patient care. In addition to the phenomenon of clinician drift, there has been a growing controversy within the field of clinical psychology about the compatibility of ESTs and multiculturalism. Some argue that the standardization inherent to EST resists the concept of cultural adaptability; while others have countered that cultural adaptability is essential in order for empirically supported treatments to remain relevant, ethical, and effective. In order to shed more light on this issue, this study examined how clinicians tend to drift from CBT in the treatment of Latinos suffering from eating disorders, in order to accommodate Latino culture and elements of eating behavior specific to Latino populations. We both attempted to replicate prior findings regarding predictors of clinician drift, as well as build upon the little existing research into the "culturally-motivated clinician drift." It was discovered that no therapist characteristics or client characteristics were predictive of drift. However, the majority of the sample still adapted or abandoned at least part of the CBT treatment. Their responses regarding the weaknesses of CBT for their Spanish-speaking clients can provide insight into how the treatment can be modified for more diverse clients.

An Evaluation of the Cognitive Effects of a Short-Term and a Long-Term Ovarian Hormone Deprivation in a Transgenic Mouse Model of Alzheimer's Disease: Addressing the Critical Window

Description
With no known cure, Alzheimer's disease (AD) is the most common dementia, affecting more than 5.5 million Americans. Research has shown that women who undergo surgical menopause (i.e. removal of the ovaries) before the onset of natural menopause are at a greater risk for AD. It is hypothesized that this…

With no known cure, Alzheimer's disease (AD) is the most common dementia, affecting more than 5.5 million Americans. Research has shown that women who undergo surgical menopause (i.e. removal of the ovaries) before the onset of natural menopause are at a greater risk for AD. It is hypothesized that this greater relative risk of developing AD is linked to ovarian hormone deprivation associated with surgical menopause. The purpose of these studies was to evaluate the behavioral changes that occur after a short-term (ST) and a long-term (LT) ovarian hormone deprivation in a mouse model of AD. Wildtype (Wt) or APP/PS1 (Tg) mutation mice underwent either a sham surgery or an ovariectomy (Ovx) surgery at three months of age. Study 1 consisted of a short-term cohort that was behaviorally tested one month following surgery on a battery of spatial memory tasks including, the Morris water maze, delayed matched-to-sample water maze, and visible platform task. Study 2 consisted of a long-term cohort that was behaviorally tested on the same cognitive battery three months following surgery. Results of Study 1 revealed that genotype interacted with surgical menopause status, such that after a short-term ovarian hormone deprivation, Ovx induced a genotype effect while Sham surgery did not. Results of Study 2 showed a similar pattern of effects, with a comparable interaction between genotypes and surgical menopause status. These findings indicate that the cognitive impact of ovarian hormone deprivation depends on AD-related genotype. Neuropathology evaluations in these mice will be done in the near future and will allow us to test relations between surgical menopause status, cognition, and AD-like neuropathology.
