Fast regression estimates of missing data

A recent comparison of methods for estimating missing data concluded that when there is sufficient redundancy to justify using a more elaborate method than the mean of each variable, the principal components and regression methods are equally good and superior to the other methods investigated. Principal components was preferred because of its tremendous computational savings over the regression method. This note proposes an alternate implementation of the regression method which should be slightly faster than the principal components method.     

Why and for whom does the pressure to help hurt others? Affective and cognitive mechanisms linking helping pressure to workplace deviance

Scholars are paying increasing attention to the “dark side” of citizenship behavior. One aspect of this dark side that has received relatively scant attention is “helping pressure”—an employee's perception that s/he is being encouraged to, or otherwise feels that s/he should, enact helping behavior at work. Drawing from theory associated with work stress, we examine affective and cognitive mechanisms that potentially explain why helping pressure, counterintuitively, may lead employees to engage in deviant behavior instead. Beyond examining these possible mechanisms, we also answer calls to identify a potential buffer to these effects. Drawing from self-determination theory, we examine how an employee's intrinsic motivation for citizenship may lessen the deleterious consequences of helping pressure at work. In two studies (a within-individual experience-sampling study and a two-wave between-individual study), we find consistent evidence that helping pressure has a positive indirect relationship with deviant behavior through increased negative affect. Further, we find evidence that intrinsic motivation for citizenship weakens the positive relationship of helping pressure with negative affect, buffering the indirect effect on subsequent deviant behavior. Theoretical and practical implications of these findings for the study of helping pressure at work are discussed.     

Biased estimators, biased experts, and the Ivory Tower: a reply to Grove (2001)

This reply responds to W. M. Grove's (2001) critique of H. O. F. Veiel and R. F. Koopman's (2001) article on bias in widely used methods of estimating premorbid IQ. In this reply, the authors show that Grove is misrepresenting part of Veiel and Koopman's arguments, extend them to show that the proposed adjustment to regression estimates of IQ not only is unbiased but also is the maximum-likelihood estimate of the true IQ, and argue that Grove's notion of the acceptability of biased methods in judicial proceedings reflects a fundamental misapprehension of their nature and purpose.     

Helping others or helping oneself? An episodic examination of the behavioral consequences of helping at work

Scholars have paid an increasing amount of attention to organizational citizenship behaviors (OCBs), with a particular emphasis on helping others at work. In addition, recent empirical work has focused on how OCB is an intraindividual phenomenon, such that employees vary daily in the extent to which they help others. However, one limitation of this research has been an overemphasis on well‐being consequences associated with daily helping (e.g., changes in affect and mental depletion) and far less attention on behavioral outcomes. In this study, we develop a self‐regulatory framework that articulates how helping others at work is a depleting experience that can lead to a reduction in subsequent acts of helping others, and an increase in behaviors aimed at helping oneself (i.e., engaging in political acts). We further theorize how two individual differences—prevention focus and political skill—serve as cross‐level moderators of these relations. In an experience sampling study of 91 full‐time employees across 10 consecutive workdays, our results illustrate that helping is a depleting act that makes individuals more likely to engage in self‐serving acts and less likely to help others. Moreover, the relation of helping acts with depletion is strengthened for employees who have higher levels of prevention focus.     

Altered Sexuality and Body Image after Gynecological Cancer Treatment: How Can Psychologists Help?

Once medical treatment for gynecological cancer is completed, what happens to patients' sexuality and body image? Due to the delicate nature of the cancer site, treating this cancer typically affects sexual functioning and body image adversely, making it critical to identify the concerns of these patients and do so in a manner less restrictive than paper-and-pencil assessment. To gain a deeper understanding of the phenomenological experiences in question, we interviewed nine gynecological cancer patients and seven cancer-free women. After implementing a relaxation protocol, we asked each woman to describe her feelings and thoughts on her sexuality and body image in one-on-one interviews. A variety of themes emerged on patients' attitudes and perspectives concerning sexuality and body image following diagnosis and treatment of the cancer. The themes that were considerably different from those of the cancer-free women included decreased sexual functioning and body image, abrupt shifts in self-identity due to loss of physical integrity, and distancing in intimate relationships. Several implications of these findings for clinical practice are discussed, as well as the need to train medical professionals to properly assess these patients' alterations in sexuality.     

Political Psychology as a Lens for Viewing Traumatic Events

A burgeoning area of scientific inquiry uses psychological perspectives to understand traumatic events. This research has led to the identification of psychological symptoms and disorders frequently experienced in response to traumatic events. Many of the events having traumatic effects on large numbers of persons are of interest to political psychologists. Such events include the Holocaust, war, terrorism, captivity, torture, political migration, living as a political refugee, and assassination. Some interpersonal forms of trauma, such as rape and incest, also may be viewed with a political perspective. Although a number of studies have examined psychological consequences of political events, this area of inquiry is rarely explicitly considered within the domain of political psychology. Adopting an explicitly political psychology perspective on traumatic events may enrich our interdisciplinary understanding of these events and inform the design and evaluation of intervention programs to reduce psychological distress resulting from these events.
