Innovative interventions for disordered eating: evaluating dissonance-based and yoga interventions.

OBJECTIVE: Eating-disordered behavior is prevalent among college women. Few interventions have successfully reduced risk factors for these behaviors, however. The most promising interventions are both selective and interactive. This study compared two newer types of interventions that meet these criteria: cognitive dissonance and yoga programs. METHOD: This study advertised programs for women who were dissatisfied with their bodies. Participants (N = 93) were randomly assigned to dissonance, yoga, or control groups. RESULTS: Hierarchical regression analyses revealed that there were no significant post-intervention differences between the yoga and control groups. Dissonance group participants had significantly lower scores than the scores of both other groups on measures of disordered eating, drive for thinness, body dissatisfaction, alexithymia, and anxiety. CONCLUSION: These findings have important implications for interventions on college campuses. In particular, dissonance interventions appear to be an efficient and inexpensive approach to reducing eating disorder risk factors. Additional research regarding the value of yoga interventions is needed.

Subglottic secretion viscosity and evacuation efficiency.

Ventilator-associated pneumonia (VAP) is a common nosocomial pneumonia that occurs in critically ill patients and results in mortality rates as high as 71%. Subglottic secretions (SSs) are a known risk factor. Several clinical trials have shown that continuous aspiration of subglottic secretions (CASS) reduces the risk of VAP by nearly half. Optimal suction pressure levels needed to efficiently evacuate viscous SSs are unknown. The purpose of this study was to describe SSs and the effective suction pressure (20 mmHg, 30 mmHg, 40 mmHg, and 50 mmHg) needed to maximize evacuation efficiency based on SS volume (2 ml, 4 ml, and 6 ml) and viscosity (watery, thick, and gel-like). A laboratory model was designed to replicate a human trachea. Thick secretions had the highest percentage of mean recovery representative of evacuation efficiency of SSs (mean recovery of 86%). The suction pressure of 30 mmHg had the highest overall mean of secretion recovery (83%) across all viscosity types and amounts. This study demonstrated that higher viscosity secretions were easier to evacuate than lower viscosity secretions when 30-mmHg suction pressure was applied. Management of secretion viscosity may assist in secretion removal and delay VAP development. With increased understanding of the molecular structure of SSs, there is the potential that clinicians will be able to manipulate secretion viscoelastic properties to maximize evacuation efficiency of the secretions. Further research is needed to identify safe suction pressures for optimal evacuation of SSs in human subjects.

Factor structure of the Smith irrational beliefs inventory: results of analyses on six independent samples.

This study reports the results of six factor analyses (alpha factoring, direct oblimin rotation, Delta= .4) on six items from the Smith Irrational Beliefs Inventory. Six independent samples of 1851 college students (521 men, 1,280 women, 50 sex unstated) were tested. Three factors emerged with identical content for each analysis. Distorted Egocentrism was defined by two items reflecting feelings of entitlement and the naive assumption that events should always turn out favorably the way one desires; Task Exaggeration/Catastrophizing was defined by two items directly depicting a tendency to view challenges as overwhelming and catastrophic; and Isolated Low Self-esteem was defined by two items expressing the feeling that one has unacceptable feelings that could lead to isolation or rejection. Previous research on other irrational belief inventories has yielded inconsistent results, with multifactorial solutions emerging for clinical samples and unifactoral solutions for student samples. That the present six factor analytic studies yielded a consistent multifactoral set of irrational beliefs for a very large student sample suggests that factors do emerge when items are initially screened and the subject population is carefully defined.
