Antecedents of communication apprehension: A reaffirmation

This study examines the relationship between communication apprehension (CA) and students’ self‐reports of their communication experiences in interpersonal, small group, and public circumstances with peers, parents, and teachers. Questions concerning these experiences were posed from reinforcement, modeling, and social comparison perspectives. The strongest relationships were found between CA and reinforcement oriented questions that involved teachers in public speaking settings. Those with high CA found giving speeches with teachers present to be non‐rewarding The study also found support for a relationship between modeling and CA.     

Visualization: The next generation

The purpose of this study was to determine whether adding an educational component to visualization (a procedure designed to reduce public speaking apprehension) increases the effectiveness of visualization. These data indicate that combining visualization and education is superior to either education or visualization alone or a no treatment control group in reducing self‐reported public speaking apprehension.     

An assessment of the role of communication apprehension in communicating with the terminally ill

Students who reported being high or low communication apprehensives in interpersonal encounters were asked to read a letter from a terminally or not terminally ill patient and write a letter in reply. These students also completed a variety of self‐report measures. In essence, high CAs were found to be less willing to communicate, less willing to volunteer, less willing to work with terminal patients, and felt less confident about their communication than low CAs. High CAs also disclosed less to terminal patients than did people in any other circumstance. Further, terminal patients who were depicted as quiet received less self‐disclosure and less communication that was sensitive to their perspective than did those in any other circumstance.     

Two studies concerning the predictive validity of the personal report of communication apprehension in employment interviews

Two studies were conducted to provide evidence concerning the predictive validity of the Personal Report of Communication Apprehension in Employment Interviews (PRCAEI). The first study, conducted in a laboratory setting, indicated that those who scored relatively high on the PRCAEI were recommended to be hired less often than those with relatively low PRCAEI scores. High PRCAEIs were also seen as less trustworthy, less task oriented, and less socially attractive than low PRCAEIs. The second study, conducted in the field, found a negative relationship (‐.84) between candidates’ scores on the PRCAEI and the rank they were given by an interviewer. That is, the higher one's PRCAEI score, the lower interviewers ranked him or her relative to others interviewing for the position. These studies offer strong support for the predictive validity of the PRCAEI and suggest CA is an extremely important variable in job interviews.     

Agreement between bioelectrical impedance and dual energy X-ray absorptiometry in assessing fat,lean and bone mass changes in adults after a lifestyle intervention

We aimed to assess the agreement of a commercially available bioelectrical impedance analysis (BIA) device in measuring changes in fat, lean and bone mass over a 10-week lifestyle intervention, with dual energy X-ray absorptiometry (DXA) as reference. A sample of 136 volunteers (18–66 years) underwent a physical activity intervention to enhance lean mass and reduce fat mass. BIA (Tanita BC545) and DXA (Hologic Explorer) measures of whole-body composition were taken at baseline and at the end of the intervention. After an average of 74 ± 18 days intervention, DXA showed significant changes in 2 of 3 outcome variables: reduced fat mass of 0.802 ± 1.092 kg (P < 0.001), increased lean mass of 0.477 ± 0.966 kg (P < 0.001); minor non-significant increase of 0.007 ± 0.041 kg of bone mass (P = 0.052). The respective changes in BIA measures were a significant reduction of 0.486 ± 1.539 kg fat (P < 0.001), but non-significant increases of 0.084 ± 1.201 kg lean mass (P = 0.425), and 0.014 ± 0.091 kg bone (P = 0.074). Significant, but moderately weak, correlations were seen in absolute mass changes between DXA and BIA: 0.511 (fat), 0.362 (lean) and 0.172 (bone). Compared to DXA, BIA demonstrated mediocre agreement to changes in fat mass, but poor agreement to lean mass changes. BIA significantly underestimated the magnitude of changes in fat and lean mass compared to DXA.     

The influence of student experiences on post-graduation surveys

This study attempts to establish the extent to which in-class teaching quality instruments can be used to predict post-graduation survey results. It examines the responses for the Good Teaching Scale of the Course Experience Questionnaire administered to 10,433 students who completed their studies at a major Australian tertiary institution from 2003 to 2005 using a unique data-set that matched student records and measures of class characteristics to the individual survey responses. The findings indicate that the overall degree experiences of particular students can be predicted by measures of class differences as measured by teaching quality instruments and the grade distributions of the classes they completed. These factors are in addition to the effects of students’ own performance as measured by their grades, their field of study and their post-graduation experience. It was found that in-class administered teaching quality instruments have an asymmetric influence on post-graduation survey results. Higher than expected scores appear to have little impact, and lower than expected results were found to have a significant negative impact on post-graduation recollections. The grade distribution in classes taken was also found to be an important factor in explaining variation in degree satisfaction.
