Vengeance: Effects of gender, age, and religious background

AbstractVengeance can be commonly defined as the infliction of harm in return for perceived injury or insult or as simply getting back at another person. Three hundred fifty‐three participants responded to eight hypothetical scenarios that may elicit vengeful behavior in which the offending party was either a romantic partner, a friend, a coworker, or a stranger. Participants also completed a vengeance scale and a measure of biblical literalism. Participants were most vengeful toward coworkers and least vengeful toward romantic partners. Age, religious conservatism, and gender were significant predictors of attitudes toward vengeance. Although men were more likely than women to be accepting of vengeful attitudes as measured by the vengeance scale, only age was a significant predictor of behavior in the vengeance scenarios. The current research provides a basis for a systematic investigation of vengeance within the structure of human relationships and interactions. Aggr. Behav. 27:343–350, 2001. © 2001 Wiley‐Liss, Inc.

Prenatal alcohol exposure and childhood behavior at age 6 to 7 years: I. dose-response effect.

Moderate to heavy levels of prenatal alcohol exposure have been associated with alterations in child behavior, but limited data are available on adverse effects after low levels of exposure. The objective of this study was to evaluate the dose-response effect of prenatal alcohol exposure for adverse child behavior outcomes at 6 to 7 years of age. Beginning in 1986, women attending the urban university-based maternity clinic were routinely screened at their first prenatal visit for alcohol and drug use by trained research assistants from the Fetal Alcohol Research Center. All women reporting alcohol consumption at conception of at least 0.5 oz absolute alcohol/day and a 5% random sample of lower level drinkers and abstainers were invited to participate to be able to identify the associations between alcohol intake and child development. Maternal alcohol, cigarette, and illicit drug use were prospectively assessed during pregnancy and postnatally. The independent variable in this study, prenatal alcohol exposure, was computed as the average absolute alcohol intake (oz) per day across pregnancy. At each prenatal visit, mothers were interviewed about alcohol use during the previous 2 weeks. Quantities and types of alcohol consumed were converted to fluid ounces of absolute alcohol and averaged across visits to generate a summary measure of alcohol exposure throughout pregnancy. Alcohol was initially used as a dichotomous variable comparing children with no prenatal alcohol exposure to children with any exposure. To evaluate the effects of different levels of exposure, the average absolute alcohol intake was relatively arbitrarily categorized into no, low (>0 but <0.3 fl oz of absolute alcohol/day), and moderate/heavy (>/=0.3 fl oz of absolute alcohol/day) for the purpose of this study. Six years later, 665 families were contacted. Ninety-four percent agreed to testing. Exclusions included children who missed multiple test appointments, had major congenital malformations (other than fetal alcohol syndrome), possessed an IQ >2 standard deviations from the sample mean, or had incomplete data. The Achenbach Child Behavior Checklist (CBCL) was used to assess child behavior. The CBCL is a parent questionnaire applicable to children ages 4 to 16 years. It is widely used in the clinical assessment of children's behavior problems and has been extensively used in research. Eight syndrome scales are further grouped into Externalizing or undercontrolled (Aggressive and Delinquent) behavior and Internalizing or overcontrolled (Anxious/Depressed, Somatic Complaints, and Withdrawn) behaviors. Three syndromes (Social, Thought, and Attention Problems) fit neither group. Higher scores are associated with more problem behaviors. Research assistants who were trained and blinded to exposure status independently interviewed the child and caretaker. Data were collected on a broad range of control variables known to influence childhood behavior and/or to be associated with prenatal alcohol exposure. These included perinatal factors of maternal age, education, cigarette, cocaine, and other substances of abuse and the gestational age of the baby. Postnatal factors studied included maternal psychopathology, continuing alcohol and drug use, family structure, socioeconomic status, children's whole blood lead level, and exposure to violence. Data were collected only from black women as there was inadequate representation of other racial groups. Statistical analyses were performed using the SPSS statistical package. Frequency distribution, cross-tabulation, odds ratio, and chi(2) tests were used for analyzing categorical data. Continuous data were analyzed using t tests, analyses of variance (ANOVAs) with posthoc tests, and regression analysis. Testing was available for 501 parent-children dyads. Almost one fourth of the women denied alcohol use during pregnancy. Low levels of alcohol use were reported in 63.8% and moderate/heavy use in 13% of pregnancies. Increasing prenatal alcohol exposure was associated with lower birth weight and gestational age, higher lead levels, higher maternal age, and lower education level, prenatal exposure to cocaine and smoking, custody changes, lower socioeconomic status, and paternal drinking and drug use at the time of pregnancy. Children with any prenatal alcohol exposure were more likely to have higher CBCL scores on Externalizing (Aggressive and Delinquent) and Internalizing (Anxious/Depressed and Withdrawn) syndrome scales and the Total Problem Score. The odds ratio of scoring in the clinical range for Delinquent behavior was 3.2 (1.3-7.6) in children with any prenatal exposure to alcohol compared with nonexposed controls. The threshold dose was evaluated with the 3 prenatal alcohol exposure groups. One-way ANOVA revealed a significant between group difference for Externalizing (Aggressive and Delinquent) and the Total Problem Score. (ABSTRACT TRUNCATED)

Associations Among Perceived Autonomy Support, Forms of Self-Regulation, and Persistence: A Prospective Study

According to self-determination theory, when the social context is autonomy supportive, people are motivated to internalize the regulation of important activities, and whereas when the context is controlling, self-determined motivation is undermined. A model that incorporates perceptions of coaches' interpersonal behaviors (autonomy support vs. control), 5 forms of regulation (intrinsic motivation, identified, introjected and external regulation, and amotivation), and persistence was tested with competitive swimmers (N = 369) using a prospective 3-wave design. Analyses using structural equation modeling revealed that experiencing relationships as controlling fostered non–self-determined forms of regulation (external regulation and amotivation). Greater levels of self-determined motivation occurred when relationships were experienced as autonomy supportive. Individuals who exhibited self-determined types of regulation at Time 1 showed more persistence at both Time 2 (10 months later) and Time 3 (22 months later). Individuals who were amotivated at Time 1 had the highest rate of attrition at both Time 2 and Time 3. Introjected regulation was a significant predictor of persistence at Time 2 but became nonsignificant at Time 3. External regulation was not a significant predictor of behavior at Time 2, but became negatively associated with persistence at Time 3. The findings are discussed in light of the determinants of the internalization process and the consequences of different forms of self-regulation for psychological functioning.

Prediction Model of Exercise Behavior in Patients with Rheumatoid Arthritis

【Purpose: The exercise status in patients with rheumatoid arthritis, associations between exercise behavior and personal factors, and associations between exercise behavior and exercise-specific cognitions and their effects were assessed. Method: Four hundred thirty nine outpatients with rheumatoid arthritis were studied. The exercise status was measured by a single item. The intensity was multiplied by the frequency and duration of each exercise. The product of these intensity values for all exercises was defined as exercise behavior. Based on the Pender's revised health promotion model, exercise benefit, barrier, self-efficacy, enjoyment and social support were chosen as exercise specific cognitions and affect variables. Path analysis was used to identify the predictors of exercise behavior. Results: Compared to the duration before being diagnosed, the number of subjects who exercised regularly increased after being diagnosed. However over half of the subjects refrain from any sort of exercise and the type of exercise is very limited. Among the variables, exercise barrier, self-efficacy, and social support were found to be significant predictors of exercise behavior, and only previous exercise experience was found to be significant predictors of all behavior specific cognitions and affect variables. Conclusion: These findings suggest that studies should explore exercise behaviors and strategies to emphasize the cognitive-motivational messages to promote exercise behaviors.】

Test of the Fishbein and Ajzen models as predictors of health care workers' glove use

The aim of this study was to identify predictors of health care workers' glove use when there is a potential for blood exposure. The study hypothesis was that an extension of the theory of planned behavior would explain more of the variance in glove use behavior than the theory of reasoned action or theory of planned behavior. A random sample of nurses and laboratory workers (N = 527) completed a 26-item questionnaire with acceptable content validity and reliability estimates. Using structural equation modeling techniques, intention, attitude, and perceived risk were significant predictors of behavior. Perceived control and attitude were the significant determinants of intention. The theory of reasoned action was the most parsimonious model, explaining 70% of the variance in glove use behavior. The theory of planned behavior extension was a viable model to study behavior related to glove use and reducing workers' risks to bloodborne diseases. © John Wiley & Sons, Inc.

Perceptual Deterrence and the Mediating Effect of Internalized Norms among Inner-City Teenagers

Two limitations of perceptual deterrence research are that it generally uses samples with high stakes in conformity and does not examine interrelations between the threat of legal sanctions, social sanctions, and internalized norms. Although some results suggest that the perceived certainty of legal sanctions deters, little is known about perceptions of inner-city teenagers responsible for a disproportionate amount of recorded crime. This study tested the hypotheses that perceived risk of arrest would not relate to delinquency among a sample of inner-city high school students and that internalized norms mediate the relation between social sanctions and delinquency. Risk of arrest was not related to self-reported delinquency, even at the bivariate level; and multivariate analyses indicated that peers, adult models, and the severity of parents' punishment were the significant predictors of behavior. The results also supported the hypothesis that internalized norms mediate the impact of social sanctions associated with delinquency.

Sexual behavior and vaginal colonization by group B streptococcus among minority women

To test the hypothesis that sexual behaviors predict colonization of the vagina by group B streptococcus among minority women. We conducted a prospective, descriptive study of 192 consecutive African-American (37%) and Hispanic women (63%). Each woman underwent a detailed interview concerning sexual behavior. Separate specimens were taken from the endocervix, upper vagina, lower vagina, and anorectum and placed in selective broth media for isolation of group B streptococcus. Significant behavioral predictors of vaginal group B streptococcus colonization and heavy (3-4+) colonization were identified using stepwise logistic regression. The incidence of vaginal colonization was 39% and heavy colonization was 35%. Nineteen percent reported anal intercourse, 46% reported sex at least two times per week, and 21% reported more than one partner in the previous 30 days. The significant predictors of vaginal group B streptococcal infection were: African-American ethnicity, adjusted odds ratio (OR) 6.1 (95% confidence interval [CI] 2.5-15.1); presence of rectal group B streptococcus, adjusted OR 100.6 (95% CI 26.7-379.3); nulliparous, adjusted OR 3.6 (95% CI 1.4-9.5); and nonpregnant status, adjusted OR 3.9 (95% CI 1.3-12.2). The significant predictors of heavy colonization were: more than one partner in the last 30 days, adjusted OR 2.6 (95% CI 1.2-5.6); and African-American ethnicity, adjusted OR 2.3 (95% CI 1.2-4.5). Anal intercourse was associated with a reduced likelihood of vaginal group B streptococcal infection, adjusted OR 0.34 (95% CI 0.12-0.91). Sexual behavior, especially anal intercourse, does not predict vaginal colonization by group B streptococcus. African-American women are more likely to have vaginal and heavy group B streptococcus colonization. Heavy vaginal colonization is associated with multiple partners in African-American women.

Black-white differences in cancer prevention knowledge and behavior.

Data from the 1987 National Health Interview Survey Cancer Control Supplement were used to estimate multivariate logistic regression models of diet change, mammography utilization, stool blood test utilization, and smoking. Predictor variables included race, sex, age, income, dietary concerns, and four knowledge-related variables: education and three measures of cancer prevention knowledge. When knowledge variables were included in the models, race was not a significant predictor of behavior, with one exception: among women, Blacks were found to smoke less than Whites.

Using attitudes and subjective norms to predict pharmacist counselling behaviors

This field study examines the applicability of the central components of Fishbein and Ajzen's model for the prediction of behavior to the medication counselling activities of community pharmacists. The findings from a sample of 40 pharmacists provide support for the attitudes-subjective norms model. Both the attitude and subjective norm measures are significant predictors of behavior for verbal instruction provided and the length of encounter time. Each of the other behaviors examined—written instruction provided, monitoring activity, and pharmacist approachability—is weakly to moderately influenced by one of the two independent variables.
