Sleep duration and self-reported Type A behavior: a replication.

Scores on the Jenkins Activity Survey (Form T)(Glass, 1977) were compared for 58 and 70 university students who reported, respectively, a regular sleep pattern of less or more than 8 hr per night. Replicating a previous report (Hicks et al., 1979), subjects who slept fewer hours scored higher on Type A behavior questions than those who slept more hours. However, for subjects with a less stable sleeping pattern, Type A scores for the two groups (ns = 72, 23) did not differ.     

Imaginal correlates of self-reported fear and avoidance behavior

Two analogue studies explored the relationship between the content of subjects' imagery and both behavioral avoidance and self-reports of fear. In the first study, reports of aversive imagery in a fearful situation were much more frequent among high- as compared to low-avoidance subjects. Reports of aversive imagery were found significantly associated with both fear and avoidance behavior. In the second study, findings were extended, indicating that imagery content is associated with fear and avoidance when subjects imagine themselves in a fearful situation as well as when they are actually in one. This suggested some degree of functional equivalence between imagined and real situations. However, no relationship was found between image clarity and either fear or avoidance. Since imagery appears to play an important role in mediating fearful behavior, manipulation of imagery might serve as an effective treatment strategy.     

Students' knowledge of AIDS and sexual risk behavior.

College students appear to be knowledgeable of the methods of transmission and risks of the AIDS virus. However, the reality of susceptibility to infection does not seem to have altered their conduct. In a study of 19 heterosexual college students, knowledge and intention do not appear to be good predictors of sexual behavior. Young people appear to continue high-risk sexual behavior even while knowledgeable of the risks of AIDS.     

Pain sensitivity and individual differences in self-reported sexual behavior

The relationship between sexual behavior and pain sensitivity was assessed in 27 heterosexual men and 20 heterosexual women. Sexual behavior measures included sexual motivation and ratings of subjective sexual arousal to and enjoyment of an auditory stimulus. Pain sensitivity measures were pain threshold and pain tolerance in a cold pressor task. Participants were tested after exposure to a neutral or a sexual audio stimulus. Exposure to the sexual stimulus increased pain sensitivity in women but not in men. However, sexual behavior measures were correlated with pain threshold for both men and women. Specifically, higher pain thresholds were associated with weaker sexual motivation, lower enjoyment potential for sexual interaction, and increased inhibition during intercourse. These results are consistent with findings in laboratory animals, suggesting that differences in sexual behavior may reflect differences in responsiveness to a variety of stimuli.     

An international comparative study of self-reported driver behavior

Using a large data base of 20,725 questionnaires from 19 European countries, this article uses a combination of factor analysis and tree based regression to determine driver groups with homogeneous self-reported behavior and determine whether regional differences in driving behaviors exist. Self-reported behavior, including speeding, reckless driving, seat belt use, and drinking and driving are examined. The results suggest that speeding and general reckless (dangerous) behavior are related, perhaps capturing a driver's “risk taking” or “pre-trip violations” behavior. Similarly, seat belt use and driving under the influence of alcohol are also related and may represent a driver's “law abiding” tendency or “during-trip violations” behavior. Further, important regional differences and similarities between European drivers are uncovered. Northern European drivers report a significantly higher compliance with drinking and driving laws and seat belt use regulations than do Southern and Eastern European drivers.     

Psychosocial predictors of gay men's AIDS risk-reduction behavior.

Used psychosocial variables derived from the health belief model (Rosenstock, 1974), Bandura's (1986) self-efficacy framework, and protection motivation theory (Rogers, 1984) to predict self-reported AIDS risk-reduction behaviors in a sample of 389 homosexual men who participated in the Multicenter AIDS Cohort Study in Los Angeles and who knew their HIV antibody status. Hierarchical multiple regression analyses showed that self-efficacy, perceived risk, response efficacy, and prior sexual behavior accounted for approximately 70% of the variance in the total number of sexual partners and the number of anonymous partners over a 6-month interval, controlling for demographic variables, HIV antibody status, and presence of a primary partner. A logistic regression analysis showed that barriers to change predicted increased unprotected anal receptive intercourse over a 6-month interval, controlling for prior behavior. The relation of health beliefs to risk-reduction behavior was substantially different for HIV-seropositive men without primary partners than for other groups of gay men. Implications for interventions are discussed.     

Associations of symptoms of anxiety disorders and self-reported behavior problems in normal children

61 children, aged between 14 and 18 years, completed the Screen for Child Anxiety Related Emotional Disorders, a scale of anxiety disorders symptoms, and the Youth Self-report, a measure of internalizing, i.e., emotional, and externalizing, i.e., behavioral, problems. Analysis showed that, with the exception of the Social Phobia and the Specific Phobia subscales, Screen total and subscale scores were significantly related to Internalizing problems (rs between .40 and .77). Thus, the more frequently children reported Anxiety Disorder symptoms, the more often they reported emotional problems. Furthermore, in particular, anxious-depressed problems as measured by the Youth Self-report were significantly associated with scores on Screen scales. These results further support the concurrent validity of the Screen.     

Personality characteristics of alcohol dependent inpatients: relationship of MCMI subtypes to self-reported drinking behavior.

Recent cluster analytic research with alcoholic inpatients has demonstrated the existence of several Millon Clinical Multiaxial Inventory (MCMI) clusters that appear to be consistent across different subject samples. The validity of these data would be strengthened by a statistical demonstration of the similarity of attained clusters across studies--a demonstration of concordance of subject classification across different clustering techniques on the same data set- and the inclusion of external, independent measures against which to evaluate the predictive validity of the cluster typology. We found a high level of concordance in subject classification across different clustering methods on the same data set and a high level of agreement with cluster typologies attained in previous studies. Subsequent multivariate analyses employing independent scales measuring various aspects of alcohol use confirmed differences among cluster members on perceived benefits of alcohol use and deleterious effects of alcohol use. The prominent differences in alcohol use along with a rationale for their development are discussed.     

Reality therapy: Icing on the cake of behavior modification

The paper presents a conceptual model for therapeutic intervention based on a behavioral orientation. Behavioral therapy is viewed on a continuum ranging from basic operant techniques to cognitive strategies applied to human interaction. It is hypothesized that the elements of reality therapy, with its emphasis on human interaction, are needed to provide closure to the therapeutic intervention and to help maintain new coping behaviors. Utilizing the context of an institutionalized client, suggestions for how this process might occur are discussed.     

Coping with spousal loss: potential buffering effects of self-reported helping behavior

The present study examined the role of self-reported helping behavior in attenuating the helper's depression following spousal loss. Using archival data from the Changing Lives of Older Couples sample (N = 289), the study shows that among bereaved participants who had experienced high loss-related grief, helping behavior (providing instrumental support to others) was associated with an accelerated decline in depressive symptoms for the helper from 6 months to 18 months following spousal loss. This relationship between giving help and recovery from depression was independent of support received, as well as measured health, and interpersonal and demographic factors. Implications of these results for theoretical approaches to the study of close relationships and well-being are discussed.     

Attitudes towards people with AIDS and avoidance behavior: Automatic and reflective bases of behavior

We tested the assumption that implicit attitude measures are related to automatic behavior, while explicit attitude measures are related to reflective behavioral intentions. In our study, attitudes towards persons with AIDS were assessed with both the Implicit Association Test (IAT) and an explicit attitude measure. Behavioral intentions were measured through a questionnaire. Automatic approach and avoidance predispositions were operationalized as the speed with which a computer mouse was either pulled towards (approach) or pushed away from the body (avoidance). Consistent with our expectations, the IAT was related to the automatic approach and avoidance behaviors, while the explicit attitude measure was related to behavioral intentions. These findings support the idea that automatic and reflective processes exert independent effects on behavior.     

虚拟与虚拟实在

Analysis of correlations between psychological factors and self-reported behavior of motorcyclists in Malaysia,depending on self-reported usage of different types of motorcycle facility

Segregated road lanes for motorcyclists are one of the practices implemented by the Malaysian authority to decrease the number of road crashes involving motorcycles. In this study, the motorcycle lanes are divided into three types, exclusive, inclusive, and paved shoulder. This study examined the correlations between motorcyclists’ psychological factors and their risky riding behaviors (speeding and neglecting to wear helmet), depending on self-reported usage of different types of motorcycle facilities. The psychological factors discussed in this study were: attitude, desire, perceived behavior control, moral obligation, perceived danger, fear of being caught, and perception of others’ behaviors toward the risky behaviors. Quantitative analyses, including Structural Equation Modeling, were used as the analytical tools. The results demonstrated the statistically significant relationship of exclusive road lanes’ usage on speeding behavior. However, no statistically significant correlation was found for segregated lanes’ usage on helmet wearing behavior. Psychological factors were found affecting the motorcyclists’ likelihood of performing the risky behaviors. However, these factors influence speeding and helmet wearing behavior differently. The study offers recommendations and theoretical contributions to explain the complex relationships among the uses of segregated lanes, riders’ psychological factors, and their risky behaviors.     

Exploring biases in self-reported exercising behavior heuristics based on recency, frequency, and preference

This study investigated biases in the recall of frequency and duration of physical exercise. Following an initial computer-administered self-report interview, 77 subjects maintained diaries for four weeks, in which they recorded the day, time, duration, and type of each exercising bout. Then the interview was administered again, and subjects recalled they exercised more often and for shorter durations than they recorded in their diaries. While social desirability may explain the overestimation of the number of days exercised, the underestimation of exercise duration poses a puzzle. The heuristic of frequency, recency, or prototype could not account for this underestimation. Alternative explanations are explored. Self-reported estimates of exercising duration and frequency should not be taken at face-value until the processes and heuristics used to record and recall exercising behaviors are better understood.     

Human taste contrast and self-reported measures of anxiety.

Successive negative taste contrast in humans was demonstrated with a common taste stimulus, i.e., cherry-flavored Kool-Aid. A total of 31 male and female college-aged participants rated a 7% sucrose solution which was cherry-flavored as less sweet when it was preceded by a 28% rather than a 7% sucrose solution which was cherry-flavored. Because drugs such as the benzodiazepines affect taste contrast in rats and act as anxiolytics in humans, the present experiment also examined whether several self-reported measures of anxiety were related to taste contrast in humans. Neither scores on Taylor's Manifest Anxiety Survey nor those on the State-Trait Anxiety Inventory were related to "sweetness" ratings or contrast effects.     

AIDS: late adolescents' knowledge and its influence on sexual behavior

Approximately 300 late adolescents were surveyed to assess their knowledge of AIDS, and to determine if and how their sexual behavior had changed as a result. Findings suggested that late adolescents were quite knowledgeable regarding AIDS and its transmission; however, only about one-third had altered their sexual behavior as a result of fear of the disease. Findings are discussed in terms of the need for AIDS education, and recommendations are presented.
