Rape Rumors: The Effects of Reporting or Denying Rumors of Sexual Assaults on Campus1

Two studies examine the effects of reporting rumors of sexual assaults on a college campus. Participants read headlines and short articles about an unfamiliar college. Key headlines and articles reported an increase in sexual assaults as a fact, a rumor, a denied rumor, or a proven falsehood. Participants then rated perceptions of the college, including opinions on the level of crime and safety on campus. Results showed that both reporting the crimes as rumors and reporting denials of the rumors increased concerns compared to control conditions, but these concerns were lower than the concerns raised by reporting the assaults as fact. Findings are in line with predictions and match previous research on rumors and the impact of reported innuendo.     

The influence of unionization on job satisfaction and work perceptions

Unionized and nonunionized processing employees were compared on their perceptions of job characteristics and different facets of satisfaction. In addition, the relationship between job characteristics and job satisfaction were compared for unionized and nonunionized samples. Jobs generally were not significantly different in relation to job challenge for the two groups, but nonunionized employees reported higher levels of some satisfaction measures. The correlations between job characteristics and job satisfaction were stronger in the unionized sample. Implications of the present results and suggestions for further research are discussed.This article is based on research presented at the meeting of the Industrial Relations Research Association at Chicago, December, 1987.The author would like to thank James Martin for his help on this project.     

The use of a real-time computer diary for data acquisition and processing

Behavioural researchers have long relied on the use of diaries for the collection of self-report data. We discuss the characteristics of a programmable hand-held computer used to collect hourly and event generated data for 7 days on 20 subjects with panic disorder. In the application described, subjects answered a series of 19 or more questions on the hour from 0700 to 2300 or when they were having a panic attack. Subjects completed 88% of all the hourly ratings (range 64-98%). The system was well accepted by the subjects and provided relatively inexpensive data collection and management.     

Cardiac activity in a simple reaction time task

Twenty subjects, half having high extraversion and the other half having low extraversion scores on the Eysenck Personality Inventory, performed a simple reaction time task in which the warning stimulus was a light and the imperative stimulus was a tone. Beat-by-beat analysis showed significantly different response patterns between the two groups in time of onset, magnitude, and duration of the cardiac responses. The extraversion measures were found to relate to central-nervous-system-strength types and to indicate relative strength of central inhibitory processes, as reflected by cardiac activity.

Estimating psychological networks and their accuracy: A tutorial paper

The usage of psychological networks that conceptualize behavior as a complex interplay of psychological and other components has gained increasing popularity in various research fields. While prior publications have tackled the topics of estimating and interpreting such networks, little work has been conducted to check how accurate (i.e., prone to sampling variation) networks are estimated, and how stable (i.e., interpretation remains similar with less observations) inferences from the network structure (such as centrality indices) are. In this tutorial paper, we aim to introduce the reader to this field and tackle the problem of accuracy under sampling variation. We first introduce the current state-of-the-art of network estimation. Second, we provide a rationale why researchers should investigate the accuracy of psychological networks. Third, we describe how bootstrap routines can be used to (A) assess the accuracy of estimated network connections, (B) investigate the stability of centrality indices, and (C) test whether network connections and centrality estimates for different variables differ from each other. We introduce two novel statistical methods: for (B) the correlation stability coefficient, and for (C) the bootstrapped difference test for edge-weights and centrality indices. We conducted and present simulation studies to assess the performance of both methods. Finally, we developed the free R-package bootnet that allows for estimating psychological networks in a generalized framework in addition to the proposed bootstrap methods. We showcase bootnet in a tutorial, accompanied by R syntax, in which we analyze a dataset of 359 women with posttraumatic stress disorder available online.     

Developmental differences in risk factors for suicide attempts between ninth and eleventh graders

In order to identify differences in risk factors for suicide attempts throughout adolescence, this study utilized a school-based survey of ninth (n = 1,192) and eleventh graders (N = 1,055). Suicide attempts were associated with cigarette and alcohol use, family violence, and depression for ninth graders and with illicit drug use, school violence, and sexual abuse for eleventh graders, while having friends was protective for both groups. Additionally, having more than one risk factor imparted an exponential risk for suicide attempts (ninth > eleventh graders). The differences detected are consistent with developmental changes of adolescence and represent important information for identification of at-risk youth.
