Gender differences in death anxiety and religious orientation among US high school and college students

Women report both a higher death anxiety and extrinsic religiosity than men, but it is unknown why. Research has not previously linked these findings. We provide two alternative theoretical models of causal links: (a) womens higher death anxiety promotes extrinsic religiosity or (b) womens higher extrinsic religiosity promotes greater death anxiety. High school and college students in the United States (118 young men and 257 young women) completed Templers (1970) Death Anxiety Scale and the intrinsic and extrinsic religiosity subscales of Allport and Ross’ (1967) Religious Orientation Scale. Women reported significantly higher levels of death anxiety and extrinsic religiosity. Gender differences in extrinsic religiosity were partially explainable by gender differences in death anxiety. Also, gender differences in death anxiety could partially be explained by gender differences in extrinsic religiosity. This provides future research with some direction in the link between gender, religious orientation, and death anxiety. It also underscores recent arguments that religious motivations vary between cultures and groups.

Parental Care Aids, but Parental Overprotection Hinders, College Adjustment.

Previous work has shown that students who have troublesome relationships with their parents show higher risk factors for poorer college adjustment. In the present study, we focused on the balance between two key aspects of parenting style, parental care and overprotection, as they affect the transition to college life. Eighty-three undergraduate college students completed the College Adjustment Scales and the Parental Bonding Instrument. The most successful college adjustment was seen in students with parents viewed as providing the unique combination of high care and low overprotection. Higher parental care and less overprotection were significantly associated with better college adjustment across several domains of college-related problems, including academic problems, anxiety, interpersonal problems, depression, self-esteem problems, and family problems. Both maternal and paternal care was critical for successful college adjustment. These results have important implications for understanding how familial issues powerfully influence college adjustment and student retention, and provide compelling evidence of the need for limits to parental support in students entering college.

Preferred Interpersonal Distances: A Global Comparison

Human spatial behavior has been the focus of hundreds of previous research studies. However, the conclusions and generalizability of previous studies on interpersonal distance preferences were limited by some important methodological and sampling issues. The objective of the present study was to compare preferred interpersonal distances across the world and to overcome the problems observed in previous studies. We present an extensive analysis of interpersonal distances over a large data set (N = 8,943 participants from 42 countries). We attempted to relate the preferred social, personal, and intimate distances observed in each country to a set of individual characteristics of the participants, and some attributes of their cultures. Our study indicates that individual characteristics (age and gender) influence interpersonal space preferences and that some variation in results can be explained by temperature in a given region. We also present objective values of preferred interpersonal distances in different regions, which might be used as a reference data point in future studies.

Mental health symptom severity in cannabis using and non-using Veterans with probable PTSD

BACKGROUND Posttraumatic Stress Disorder (PTSD) is a disabling illness suffered by many Veterans returning from war. Some Veterans believe that cannabis may be therapeutic for PTSD. The purpose of this study was to better understand the association between cannabis use and PTSD symptoms. METHODS The study was a matched case-control cross-sectional evaluation of the psychiatric and sociocultural associations of cannabis use in Veterans with probable PTSD. Patient self-report measures were examined comparing cannabis users (cases) to non-users (controls) who were case-matched on age and gender. RESULTS Results indicated that there were no significant differences between cases and controls in mean PTSD Checklist-Civilian version (PCL-C) scores (59.2 and 59.1, respectively). There was also no association between PTSD scores and frequency of cannabis use. It was also observed that cases were more likely to be non-Caucasian, financially challenged, and unmarried. LIMITATIONS The sample is a convenience sample of Veterans being referred for a clinical assessment and therefore, sampling biases may limit the generalizability of the results to other populations including Veterans not seeking health care in the Veterans Affairs (VA) system. CONCLUSIONS The results do not support the theory that cannabis use would be associated with less severe PTSD symptoms. Results do suggest important sociocultural differences in cannabis users compared to controls.

Changes in Appearance in the Presence of Major Stress Events

The relationship between experiencing major stress events (MSEs) and changes in appearance (CAs) was studied in a sample of 128 participants. All participants completed the Major Stress Event and Changes in Appearance Inventory. Results indicated a significant correlation between experiencing MSEs and considered or actual CAs (r = .50 p < .01). Scores on the Changes in Appearance Inventory were significantly higher in groups with moderate to high scores on the Major Stress Event scale. This relationship between MSEs and CAs was affected by age but not gender. These results suggest that stressful life events may prompt body image dissatisfaction and underlie motivations for changes in body appearance to promote self-image. Successive or dramatic appearance changes may be an important signal of stressful experiences.

Global Study of Social Odor Awareness

Olfaction plays an important role in human social communication, including multiple domains in which people often rely on their sense of smell in the social context. The importance of the sense of smell and its role can however vary inter-individually and culturally. Despite the growing body of literature on differences in olfactory performance or hedonic preferences across the globe, the aspects of a given culture as well as culturally universal individual differences affecting odor awareness in human social life remain unknown. Here, we conducted a large-scale analysis of data collected from 10 794 participants from 52 study sites from 44 countries all over the world. The aim of our research was to explore the potential individual and country-level correlates of odor awareness in the social context. The results show that the individual characteristics were more strongly related than country-level factors to self-reported odor awareness in different social contexts. A model including individual-level predictors (gender, age, material situation, education, and preferred social distance) provided a relatively good fit to the data, but adding country-level predictors (Human Development Index, population density, and average temperature) did not improve model parameters. Although there were some cross-cultural differences in social odor awareness, the main differentiating role was played by the individual differences. This suggests that people living in different cultures and different climate conditions may still share some similar patterns of odor awareness if they share other individual-level characteristics.
