The gulf war: Distressful reactions to scud missiles attacks

This study investigated the relationships among coping strategies, trait anxiety and distressful reactions (State anxiety and fears and symptoms) of Israeli civilians under missile attack during the 1991 Gulf war. During the war sixty-six subjects (46 females and 20 males) completed a questionnaire that measured their distressful reactions and included fears in various situations (e.g., during the night, in the sealed room) and various symptoms (e.g., sleep disturbances, sensitivity to noise). In addition each subject completed the Coping Inventory for Stressful Situations (CISS, Endler & Parker, 1990a), a multidimensional self-report measure of coping which measures three major coping strategies: task-oriented, emotion-oriented and avoidance-oriented. Subjects also completed the State and Trait anxiety scales of the Endler Multidimensional Anxiety Scales (EMAS, Endler, Edwards, & Vitelli, 1991). The state anxiety scales measure two components of the individual's state anxiety, cognitive worry and autonomic emotional reactions. The trait anxiety scales measure the individual's predisposition to experience anxiety in four different situations: social evaluation, physical danger, ambiguous situations and daily routines. The results showed that individuals who used emotion-oriented coping more frequently, experienced more state anxiety and symptoms and fears, (i.e., experienced greater distress) during the war. Task-oriented and avoidance-oriented coping were not related to the distressful reactions. It was further found that subjects high on physical danger trait anxiety and social evaluation trait anxiety experienced greater fears and more symptoms (i.e., experienced greater distress) during the war. Persons high on social evaluation trait anxiety also experienced great cognitive-worry state anxiety. The results are discussed within the framework of the multidimensional model of stress, anxiety and coping (Endler, 1988; Endler & Parker, 1990a, 1990b) and the special characteristics of the Gulf war situation.     

Effect of the 5-HTTLPR polymorphism on posttraumatic stress disorder,depression, anxiety,and quality of life among Iraq and Afghanistan veterans

Background and Objectives: Posttraumatic stress disorder (PTSD), depression, anxiety, and stress are significant problems among returning veterans and are associated with reduced quality of life. Design: A correlational design was used to examine the impact of a polymorphism (5-HTTLPR) in the serotonin transporter promoter gene on post-deployment adjustment among returning veterans. Methods: A total of 186 returning Iraq and Afghanistan veterans were genotyped for the 5-HTTLPR polymorphism. Symptoms of PTSD, depression, general stress, and anxiety were assessed along with quality of life. Results: After controlling for combat exposure, age, sex of the participant, and race, 5-HTTLPR had a significant multivariate effect on post-deployment adjustment, such that S′ carriers reported more post-deployment adjustment problems and worse quality of life than veterans homozygous for the L′ allele. This effect was larger when the analyses were restricted to veterans of European ancestry. Conclusions: Our findings suggest that veterans who carry the S′ allele of the 5-HTTLPR polymorphism may be at increased risk for adjustment problems and reduced quality of life following deployments to war zones.     

Sleep Deprivation and Dating Aggression Perpetration in Female College Students: The Moderating Roles of Trait Aggression,Victimization by Partner,and Alcohol Use

Dating aggression, whether it is physical or psychological, is a major social concern. The background-situational model is highly predictive of dating aggression, but it lacks consideration of biopsychosocial processes. Sleep was investigated as one such process. A sample of 108 university undergraduate women completed objective (actigraphy) and subjective measures of sleep quality as well as self-reports of dating and trait aggression. Indicators of sleep deprivation were associated with greater frequency of dating aggression perpetration. Associations were especially strong when trait aggression and victimization by the partner were higher. Contrary to hypotheses, alcohol consumption did not significantly moderate the relation between sleep and women’s aggression perpetration. Less sleep was associated with women’s more frequent aggression toward their partners, perhaps because sleep deprivation causes difficulties with emotion regulation.     

The Relation of Birth Order,Age of Mother,and Size of Family to Intelligence

Variables thought to be associated with the magnitude of interrelationship observed among the elements in a system of social attitudes were investigated. Subjects (N = 753) were asked to respond to an inventory requesting self-report and background data. Several weeks later, Ss were given two forms of the Social Attitude Scale, a scale tapping the liberalism-conservatism domain. The results indicated that those Ss who reported recent changes in religious, moral, or political attitudes displayed a more highly interconnected system of liberal-conservative attitudes than those who did not. Variables relating to active participation in social affairs tended to be associated with higher levels of attitude system organization. Sex differences were observed, with men displaying higher levels of system organization than women. This relationship held even when participation rates were taken into consideration.     

Individual and Social Factors in the Development of Graphic Symbolization

College student attitudes toward United States involvement in three international conflict areas were measured at various times during the years 1965 through 1971. An examination of the mean attitude scores obtained toward United States involvement in the Arab-Israel, India-Pakistan, and Vietnam conflicts revealed some reluctance on the part of the students to have the United States involved in any of these areas of international conflict.

Younger students were most dovish concerning United States involvement in Vietnam and were less so on the issues of the India-Pakistan and the Arab-Israel conflicts, whereas older students were more dovish regarding the issues of United States involvement in the Arab-Israel and India-Pakistan conflicts and least dovish with respect to the Vietnam conflict. Attitudes toward the involvement of the United States in both the Vietnam and Arab-Israel conflicts became significantly more dovish over time.     

The Place of Mania Among the Depressions from a Biological Standpoint

One hundred college women completed a situational story that dealt with a traditional feminine occupation, while another 100 women completed a story that dealt with a more nontraditional, masculine occupation. The stories were used to measure fear of success. All women furnished information on their college major, career aspirations, and year in school, and completed the Masculinity and Ascendency scales from the Guilford-Zimmerman Temperament Survey. Both two- and three-dimensional chi square tests of association were performed to determine the relationship between fear of success and other variables.

Results (p < .05) indicated that fear of success is greater toward a nontraditional occupation, especially for women of low ascendency, and fear of success is greater the closer women get to graduation.     

Studies in Occupational Analysis: II. Originality

Validation is defined as a general scientific procedure for investigating the nature of reality, encompassing all scientific disciplines, regardless of the utilitarian value of the information. When the process is employed in the context of a discipline such as psychology, certain subcategories emerge whose interrelations, if viewed in the light of possible or intended uses of the collected information, demonstrate the interdependence of a variety of validation procedures some of which have been viewed in the past as separate entities. A hierarchical representation of purposes and procedures is presented to facilitate an understanding of their interrelations and interdependence.     

Theory and Analysis of Total,Direct, and Indirect Causal Effects

Mediation analysis, or more generally models with direct and indirect effects, are commonly used in the behavioral sciences. As we show in our illustrative example, traditional methods of mediation analysis that omit confounding variables can lead to systematically biased direct and indirect effects, even in the context of a randomized experiment. Therefore, several definitions of causal effects in mediation models have been presented in the literature (Baron &; Kenny, 1986 Baron, R.M., &; Kenny, D.A. (1986). The moderator-mediator variable distinction in social psychological research: Conceptual, strategic and statistical considerations. Journal of Personality and Social Psychology, 51, 1173–1182. doi:10.1037/0022-3514.51.6.1173[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Imai, Keele, &; Tingley, 2010 Imai, K., Keele, L., &; Tingley, D. (2010). A general approach to causal mediation analysis. Psychological Methods, 15, 309–334. doi:10.1037/a0020761[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Pearl, 2012 Pearl, J. (2012). The causal mediation formula: A guide to the assessment of pathways and mechanisms. Prevention Science, 13, 426–436. doi:10.1007/s11121-011-0270-1[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We illustrate the stochastic theory of causal effects as an alternative foundation of causal mediation analysis based on probability theory. In this theory we define total, direct, and indirect effects and show how they can be identified in the context of our illustrative example. A particular strength of the stochastic theory of causal effects are the causality conditions that imply causal unbiasedness of effect estimates. The causality conditions have empirically testable implications and can be used for covariate selection. In the discussion, we highlight some similarities and differences of the stochastic theory of causal effects with other theories of causal effects.
