Fat, full, and happy: effects of food deprivation, external cues, and obesity on preference ratings, comsumption, and buying intentions.

This study reassesses the relative influence of internal and external cues on the behavior of obese and normal individuals. Specifically, the effects of external cues and food deprivation on preference ratings, consumption, and buying intentions were tested for overweight and normal subjects. Obese subjects were more reactive than normals to external cues as indicated by their eating more and intending to buy more food after viewing food slides as opposed to scenery slides. However, their behavior also changed in response to food deprivation, becoming more negative. The obese showed lower food consumption, lower buying intentions, and lower ratings of both food and nonfood slides in the empty condition compared to the full condition.

Predicting and understanding mothers' infant-feeding intentions and behavior: testing the theory of reasoned action.

The present study examines the applicability of Fishbein and Ajzen's theory of reasoned action to the prediction and understanding of how primiparous and multiparous mothers intended to feed their infants and how they actually fed these infants during the 6 weeks following delivery. Measures of attitudes to behavior, subjective norms, and behavioral intentions were taken during the last trimester of pregnancy. Behavior was assessed by self-report 6 weeks postpartum. In most respects the findings supported the theory of reasoned action. However, attitudes to behavior were found to make an independent and significant contribution to the prediction of infant-feeding behavior, and the previous behavior of multiparous mothers explained an independent and significant proportion of variation in their behavioral intentions. The relative importance of the attitudinal and normative components of the theoretical model tended to vary according to whether the mothers had direct experience of the criterion behavior. Further analysis revealed that mothers who breast-fed during the 6-week postpartum period differed from those who bottle-fed exclusively during this period on a number of behavioral beliefs, outcome evaluations, and normative beliefs, and on one measure of motivation to comply. The implications of these findings for the theory of reasoned action are discussed.

The effect of message framing on breast self-examination attitudes, intentions, and behavior.

In this study we tested the framing hypothesis that a pamphlet stressing the negative consequences of not performing breast self-examination (BSE) would be more persuasive than a pamphlet emphasizing BSE's positive consequences. College-aged female subjects were exposed to a loss-frame pamphlet, a gain-frame pamphlet, or a no-arguments pamphlet, or they received no pamphlet describing the importance of and the techniques for performing BSE. Attitudes toward BSE and intentions to perform BSE were assessed immediately after this intervention and again 4 months later. The follow-up also assessed subjects' postexperimental BSE behavior. Consistent with predictions, subjects who read a pamphlet with arguments framed in loss language manifested more positive BSE attitudes, intentions, and behaviors than did subjects in the other three conditions. The greater impact of the loss pamphlet could not be attributed to greater fear arousal, better memory for pamphlet content, greater perceived susceptibility to breast cancer, or stronger beliefs in BSE's efficacy on the part of the loss subjects. Only measures of perceived self-efficacy in performing BSE were differentially affected by the framing manipulation, with loss subjects reporting the greatest levels of self-confidence. The results are discussed in terms of prospect theory's framing postulate and a simpler negativity-bias conceptualization, and underlying mechanisms such as differential salience and vividness are considered. Clinical implications of the findings are also explored.

Intentional and unintentional contributions to nonspecific preparation during reaction time foreperiods.

The nonspecific preparation that follows a warning stimulus (WS) to speed responding to an impending imperative stimulus (IS) is generally viewed as a strategic, intentional process. An alternative view holds that WS acts as a conditioned stimulus that unintentionally elicits a tendency to respond at the moment of IS presentation as a result of a process of trace conditioning. These views were contrasted as explanatory frameworks for classical effects on reaction time of the duration and intertrial variability of the foreperiod, the interval between WS and IS. It is shown that the conditioning view accounts for the available data at least as well as the strategic view. In addition, the results of 3 experiments provide support for the conditioning view by showing that unintentional contributions to nonspecific preparation can be dissociated from intentional contributions.

Effects of appearance-based admonitions against sun exposure on tanning intentions in young adults.

This experiment compared the effectiveness of health-based versus appearance-based messages on university students' intentions to protect their skin against the sun's damaging rays. One hundred thirty-four Ss completed a measure of appearance motivation, then responded to 1 of 3 essays about tanning and skin cancer. One essay described the health risks of excessive sun exposure, one essay discussed the deleterious effects of tanning on physical appearance, and a control essay described the process by which tanning occurs. Overall, the essay that dealt with the negative effects of the sun on appearance was most effective in promoting intentions to practice safe-sun behaviors. However, the appearance-based essay was effective primarily among Ss who were low rather than high in appearance motivation.

A comparative test of the theory of reasoned action and the theory of planned behavior in the prediction of condom use intentions in a national sample of English young people.

Based on the theories of reasoned action (TRA) and planned behavior (TPB), predictors of condom use intentions were investigated in 949 young people (16-24 years of age) from a national survey conducted in England. Contrary to expectations, the TPB did not perform significantly better than the TRA, even among women. Measures of past behavior were the best predictors of intentions and attenuated the effects of attitude and subjective norm. There was only weak evidence for the multiplicative assumption underlying the TRA and TPB. Although the TRA components were not the strongest predictors, the beliefs on which they are based are potentially amenable to change through information-based intervention programs. A number of practical suggestions for developing intervention strategies are offered.

Relative contributions of protection motivation theory components in predicting exercise intentions and behavior.

A factorial design was employed to test the relative effectiveness of the four cognitive appraisal processes (severity, vulnerability, response efficacy, and self-efficacy) contained in the revised protection motivation theory (PMT). One hundred sixty undergraduate women read persuasive appeals for increasing exercise, which varied on these four dimensions. As predicted, both the vulnerability and self-efficacy variables enhanced intentions to exercise along with similar effects on self-reported exercising. Intentions were predictive of self-reported changes in behavior. The obtained interaction between vulnerability, self-efficacy, and response efficacy suggests that individuals employed a "precaution strategy": They intended to adopt the recommended behavior even though they held weak beliefs about its effectiveness and were not convinced of their at-risk status. These findings are compared to others obtained using the PMT, and the issue of main and interactive effects produced by the model is also addressed.

Alcohol effects on intentional behavior: dissociating controlled and automatic influences.

This research examined the effect of alcohol on intentional behavior using a process dissociation procedure to separate the influences of conscious controlled processes from those of unconscious automatic processes. In 2 identical experiments, 24 male social drinkers studied a list of words before they received either 0.56 g/kg alcohol, an alcohol placebo, or soda. Participants then performed a word stem completion test that provided estimates of controlled influences and of automatic influences on their responses. The results of the 2 experiments were consistent. Comparisons among the treatments showed that alcohol reduced conscious controlled processes and left automatic processes unchanged. The findings contribute to understanding how the drug may reduce cognitive control of intentional behavior and raise important questions concerning personal and environmental factors that might mediate these effects.

Predictors of homicidal ideation and intent in schizophrenia: an empirical study.

Correlations of age, gender, and psychosocial variables with ratings of current homicidal ideation and intent were investigated among psychiatric facility clients with schizophrenia. Multiple regression analyses revealed, irrespective of age or gender, significantly positive correlations of three psychosocial variables--manic symptoms, psychotic symptoms, and impaired global functioning--with homicidal ideation and intent. Implications for research are discussed.

An experimental test of the impact of drug-testing programs on potential job applicants' attitudes and intentions.

The effect of the presence of a drug-testing program and perceived need for the program (operationalized through accident rates, absenteeism, and theft) on potential job applicants' attitudes toward a company and intention to apply to that company was tested. Descriptions of a potential employer containing manipulations of drug-testing program (present or absent) and need for testing (high or low) were read by 163 undergraduate Ss. Participants had more positive attitudes and intentions toward companies that did not have drug-testing programs and toward companies that did not need a testing program. An interactive effect between drug testing and subjective norms on attitudes toward a company was also significant. These results suggest that organizations should consider the effect of drug-testing programs on potential job applicants and that further research about potential applicants' responses is needed.

Panel analysis of the moderating effects of commitment on job satisfaction, intent to quit, and health following organizational change.

The authors examined the moderating effects of organizational commitment on the relationship of stress with job satisfaction, intent to quit, and health during organizational turmoil. Panel data were provided by hospital employees surveyed before and after a major divisional consolidation. Findings indicated that commitment buffered the relationship between stress and job displeasure (a canonically derived variate combining residualized job dissatisfaction, intent to quit, and irritation). Stress increased job displeasure only when commitment was low.

Workplace justice, citizenship behavior, and turnover intentions in a union context: examining the mediating role of perceived union support and union instrumentality.

This study examined the relationship between workplace justice afforded by the grievance system and the union outcomes of citizenship behavior and turnover intentions and the mechanisms that underpin these relationships. Respondents (N = 187) were members of a large public sector union in Singapore. Results revealed that perceived union support and union instrumentality fully mediated the relationship between the dimensions of workplace justice and citizenship behavior directed toward the union (OCBO) and citizenship behavior directed at other union members (OCBI). Union instrumentality partially mediated the procedural justice-turnover intentions relationship.

Mechanisms linking employee affective delivery and customer behavioral intentions.

Past empirical evidence has indicated that employee affective delivery can influence customer reactions (e.g., customer satisfaction, service quality evaluation). This study extends previous research by empirically examining mediating processes underlying the relationship between employee affective delivery and customer behavioral intentions. Data were collected from 352 employee-customer pairs in 169 retail shoe stores in Taiwan. Results showed that the influence of employee affective delivery on customers' willingness to return to the store and pass positive comments to friends was indirect through the mediating processes of customer in-store positive moods and perceived friendliness. The study also indicated that employee affective delivery influences customers' time spent in store, which, in turn, influences customer behavioral intentions.

Do humans ape? Or do apes human? Imitation and intention in humans (Homo sapiens) and other animals.

A. Whiten, D. M. Custance, J.-C. Gomez, P. Teixidor, and K. A. Bard (1996) tested chimpanzees' (Pan troglodytes) and human children's (Homo sapiens) skills at imitation with a 2-action test on an "artificial fruit." Chimpanzees imitated to a restricted degree; children were more thoroughly imitative. Such results prompted some to assert that the difference in imitation indicates a difference in the subjects' understanding of the intentions of the demonstrator (M. Tomasello, 1996). In this experiment, 37 adult human subjects were tested with the artificial fruit. Far from being perfect imitators, the adults were less imitative than the children. These results cast doubt on the inference from imitative performance to an ability to understand others' intentions. The results also demonstrate how any test of imitation requires a control group and attention to the level of behavioral analysis.

Intentions to use alcohol among fifth and sixth graders: the roles of social and stress/coping motives.

This study of children in grades five and six assessed the relationship between social and stress/coping motives and students' intentions to drink in junior high school. Whereas the two motives were not seen as separate by fifth graders, they were differentiated by sixth graders, for whom they were associated--social motives more strongly than stress/coping motives--with intentions to use alcohol. Implications for the design and timing of prevention programs are considered.

Intentional weight loss in young adults: sex-specific genetic and environmental effects.

OBJECTIVE: To explore eating styles associated with intentional weight loss (IWL) and to determine whether the genetic liability in IWL is entirely shared with genetic liability affecting BMI. RESEARCH METHODS AND PROCEDURES: As part of a longitudinal assessment of various health-related behaviors in a large population-based sample of twins, eating styles, BMI, and the number of times the study participants had intentionally lost > or = 5 kg were assessed by questionnaire from 4667 male and female twins (22 to 27 years of age). Associations of eating styles and IWL were explored using polytomous logistic regression models adjusted for BMI. Sex-specific bivariate structural equation modeling was used to explore genetic and environmental correlations of BMI and IWL. RESULTS: Individuals who had engaged in IWL exhibited markedly more restricting, overeating, and alternating restricting/overeating than those in the no-IWL group. Snacking and eating in the evening were characteristic of women with at least two IWL attempts. Eating in response to visual and emotional cues was very pronounced in women who had engaged in IWL but much less so in men. IWL was estimated to have a heritability of 38% [95% confidence interval (CI), 19% to 55%] in men and 66% (95% CI, 55% to 75%) in women. The genetic covariance of BMI and IWL was 0.38 (95% CI, 0.28 to 0.47) for men and 0.45 (95% CI, 0.41 to 0.52) for women. DISCUSSION: Distinct sex differences exist in eating styles associated with IWL and in the heritability of IWL. Most genetic factors affecting BMI are different from those affecting IWL.

Intentional weight control and food choice habits in a national representative sample of adults in the UK.

OBJECTIVE: To establish the association between intentional weight control and specific eating behaviours. DESIGN: An interview-based survey of a representative sample of the UK population including questions about demographic characteristics, weight and height, intentional weight control and eating behaviours. Associations among the eating behaviours, and between weight control and eating behaviours, were examined. SUBJECTS: 1894 men and women completed the interview (70% response rate). RESULTS: Approximately equal proportions of the sample were 'not bothered about weight' (30%), 'watching their weight' (36%), or 'trying to lose weight' (28%). More men were 'not bothered' and more women were 'trying to lose'. People who were trying to lose or were watching their weight were more likely to report restricting fats, sugars, snacks, and the amount eaten at meals, than those who were not bothered, but there were no differences between weight watchers and weight losers. The overall level of restriction among weight losers was modest. There were no group differences in eating breakfast, fruits or vegetables, skipping meals or fasting. CONCLUSIONS: Around two-thirds of the adult population of the UK appear to be concerned about weight control, and this is reflected in somewhat higher than average adherence to recommended restrictive dietary habits.

Selected predictors of registered nurses' intent to stay.

This paper reports initial findings from a longitudinal study of autonomy, willingness to risk, exit/voice (E/V) and managerial environment (ME) as predictors of registered nurses' intent to stay (ITS) that is being conducted at eight Midwestern hospitals in the USA. In this two-stage study, initial findings are based on responses from 524 staff nurses. Due to the nature of the ITS variable, two logistic regression analyses were computed to test the predictive relationships of the independent variables. In the first, subjects with neutral ITS scores were grouped with subjects who had no intent to stay. Both ME and E/V were predictive of ITS. In the second analysis, the subjects with neutral ITS scores were grouped with subjects who intended to stay. In this case, only ME was predictive. While the per cent variance accounted for by these variables is not as high as some other variables reported in previous research, these variables are amenable to managerial interventions.
