Depression and Heart Rate Variability in Patients with Coronary Artery Disease (open access)

Depression and Heart Rate Variability in Patients with Coronary Artery Disease

Depression is an independent risk factor for morbidity and mortality in patients with coronary artery disease (CAD). Altered autonomic nervous system (ANS) activity, a common feature of depression, is also a risk factor for cardiac events in patients with CAD. Heart rate variability (HRV) reflects ANS activity, and reduced HRV predicts morbidity in cardiac populations. The purpose of this study was to determine whether differences in HRV exist between depressed and nondepressed patients with CAD. Twenty-one depressed inpatients, with angiographically documented CAD were retrospectively matched to 21 nondepressed CAD patients by sex, age, and smoking status. Demographic, medical, psychological interview data, and 24-hour ECG recordings were obtained. Depressed subjects had significantly lower HRV, or trends toward lower HRV, than nondepressed subjects, even after controlling for severity of CAD. Subject groups did not differ on left ventricular ejection fraction, history of myocardial infarction, or any other relevant medical variable assessed. These results suggest that depression is associated with decreased HRV in patients with CAD, and may help to explain the increased rates of cardiac events observed in CAD patients with depression.

The Effect of Ambiguity on Peak Weightlifting Performance : A Study of Experienced Weightlifters (open access)

The Effect of Ambiguity on Peak Weightlifting Performance : A Study of Experienced Weightlifters

Recent studies in the area of sport and exercise science have suggested that weightlifting performance may be significantly improved under ambiguous conditions—namely, when the amount to be lifted is unknown. In the present study, procedural concerns from previous studies examining the effect of ambiguity were noted and a methodological variation was introduced.

Effects of Meal Size and Type, and Level of Physical Activity on Perceived Masculinity, Femininity, Likability and Attractiveness (open access)

Effects of Meal Size and Type, and Level of Physical Activity on Perceived Masculinity, Femininity, Likability and Attractiveness

Previous research indicates that women are judged on the amount of food eaten and that both men and women are judged on the type of food eaten. This study is an attempt to determine whether meal size or type predominantly accounts for these findings on the variables of masculinity, femininity, attractiveness, thinness, fitness, and likability. Physical activity was also included to determine its effect on these variable. Subjects used were 313 undergraduate students. Results indicate that meal type is more influential than meal size and that physical activity significantly influences judgements of others. The results are discussed in terms of future research and relatedness to socio-cultural theories of eating disorders.

Ego Mechanisms of Defense among Child Victims of Sexual Abuse: a TAT Analysis (open access)

Ego Mechanisms of Defense among Child Victims of Sexual Abuse: a TAT Analysis

Using the Defense Mechanism Manual (Cramer, 1991), Thematic Apperception Test (TAT) stories of 29 sexually abused female subjects and 28 non-abused female clinical control subjects were rated for the frequency of use of denial, projection, and identification.

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample (open access)

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample

The purpose of this study was to examine the relationship between anorexia nervosa and several personality traits. Past research in this area has been contradictory for several reasons. Sociocultural theories have described the media's role in promoting eating disorders by portraying a thin body-type as the ideal. However, they have neglected to describe the personality ideal which our society promotes in women. It is proposed here that anorexics incorporate and oppose this ideal. Therefore, the anorexic personality is one filled with conflict.

Predictors of Compliance and Aggressive Behavior in the Presence of Command Hallucinations (open access)

Predictors of Compliance and Aggressive Behavior in the Presence of Command Hallucinations

The Schedule for Affective Disorders and Schizophrenia-Change Version (SADS-C), the Social Adjustment Scale-Patient Version II (SAS-PATII) and the Command Hallucination Questionnaire (CAQ) were administered to 86 psychotic inpatients to investigate the relationship between command hallucinations, aggressive behavior, and compliance. Two SADS-C items ("severity of hallucinations" and "depersonalization") were useful as indicators of command hallucinations. Ninety-two percent had complied with their command at least once in the past month. Three SADS-C variables related to compliance with command hallucinations were identified: middle insomnia, the belief that the voice was acting in your best interest, and overt irritability. The patients' level of distortion of reality did not appear to influence compliance rates. Results also indicated that patients who experience command hallucinations were not significantly more or less dangerous than other psychotic inpatients.

Preparedness to Counsel HIV-Positive Clients: a Survey of Practitioners (open access)

Preparedness to Counsel HIV-Positive Clients: a Survey of Practitioners

This purpose of this study was to investigate and examine the attitudes of therapists who treat HIV-positive (HIV+) clients. Specifically, therapists' perceptions of their own preparedness in dealing with specific issues and emotions of HIV+ clients were examined. Also, therapists' evaluation of their own efficacy of specific therapeutic approaches with HIV+ clients was examined. These therapists' perceptions and evaluations of all their clients in general were compared to their HIV+ clients. Comparisons were also made within the two groups.

Racial Differences in Female Achievement Motivation and Motivation to Work (open access)

Racial Differences in Female Achievement Motivation and Motivation to Work

In the present project racial differences in female achievement motivation and motivation to work were examined, and related this information to the theory that African American females, when compared to White females, are less likely to marry someone equal to themselves in the areas of education, employment, and earning potential because of an assumed shortage of suitable African-American males. It was hypothesized that African-American females would score higher on assessments of achievement motivation and motivation to work, and rate lower the likelihood of meeting and marrying a partner equal in education level, employment level, and earning potential than would White females. Data analysis supported all hypotheses. The results were discussed in the context of the female achievement motivation literature as well as the literature concerning female motivation to work.
