A FORTRAN program for computing the exact variance of weighted kappa

An algorithm and associated FORTRAN program are provided for the exact variance of weighted kappa. Program VARKAP provides the weighted kappa test statistic, the exact variance of weighted kappa, a Z score, one-sided lower- and upper-tail N(0,1) probability values, and the two-tail N(0,1) probability value.     

The link between women's body image disturbances and body-focused cancer screening behaviors: A critical review of the literature and a new integrated model for women

A large body of literature demonstrates the association between body image disturbances and health compromising behaviors among women (e.g., pathological eating, substance use, inappropriate exercise). However, given that disturbed body image is a pervasive problem, it is likely inversely related to health maintenance behaviors. Cancer screenings for breast, skin, and cervical cancer represent an important type of health maintenance behavior, yet adherence rates are low. Given the body-focused nature of these screenings, body image may be a salient predictor. This paper reviews the literature on the relationship between body image disturbances and cancer screening behaviors among women culminating in the proposal of a theoretical model. This model posits that body shame and body avoidance predict performance of cancer screenings and that variables drawn from the cancer literature, including risk perception, health anxiety, subjective norms, and self-efficacy, may moderate this relationship. Clinical implications and suggestions for research are discussed.     

A Typology of Offenders Who Use Online Communications to Commit Sex Crimes Against Minors

This study aims to present a qualitative, empirically based typology of offenders who use online communications to commit sex crimes against minors, including offenders who met victims online and those who knew them in advance. Seventy-five reports made by law enforcement officers were analyzed using a qualitative software program, during which a typology defining 4 types of offenders was identified: the expert, the cynical, the affection-focused, and the sex-focused. Each type of offender was characterized by patterns of online communication, offline and online identity, relationship dynamics with the victim, and level of sex crime expertise. The typology reveals the heterogeneous nature of sex offenders who use online communications. This diversity must be addressed to provide satisfactory interventions for both victims and offenders.     

Shared Expectations and Implicit Coordination in Tennis Doubles Teams

Very little of the existing research on team cognition has looked at sports teams. The purpose of this study was to extend previous research to the sports domain, and empirically test the relationship between one aspect of team cognition—shared expectations—and implicit coordination in 71 American tennis doubles teams. We tested a model hypothesizing a link between prior experience, shared expectations, and implicit coordination. Prior experience influenced implicit coordination directly, as well as through a positive relationship with shared expectations. The findings highlight the potential of using behavioral measures of team coordination in sport psychology.     

Analysis of trend: a permutation alternative to the F test

When the categories of the independent variable in an analysis of variance are quantitative, it is more informative to evaluate the trends in the treatment means than to simply compare differences among the treatment means. A permutation alternative to the conventional F test is shown to possess significant advantages when analyzing trend among quantitative treatments in a one-way analysis of variance. An example with and without an extreme data point illustrates the effectiveness of the permutation alternative for the analysis of trend when homogeneity of variance is compromised.     

On the relations between distinct aspects of psychological distance: An ecological basis of construal-level theory

Construal-level theory's basic assumption of a positive relationship between psychological distance and abstractness of mental representations presupposes a unitary distance construct. Although prior research testifies to convergent influences of temporal, spatial, social and reality (probability) distance, there is no direct evidence for the integration function of all four major distance aspects assessed within the same study with reference to the same target objects. Does high (low) distance in any aspect imply high (low) distance in all other aspects, or are discounting effects (e.g., high temporal distance rendering high personal distance obsolete) sometimes apparent in negative correlations? In pursuing this question, we obtained strong and regular positive correlations between all four distance aspects, across judges and judgment targets, regardless of whether freely construed future episodes or really experienced past episodes were judged. Existing ecological correlations seem to account for the positive relationship between time, space, probability and temporal distance.     

Interpersonal Features and Functions of Nonsuicidal Self‐injury

Etiological models of nonsuicidal self‐injury (NSSI) suggest interpersonal features may be important to understand this behavior, but social functions and correlates have not been extensively studied. This study addresses existing limitations by examining interpersonal correlates and functions of NSSI within a stratified random sample of 1,243 predominantly Caucasian college students (mean age = 21.52, SD = 4.15 years). Participants completed an anonymous online survey assessing NSSI features, perceived social support, and disclosure experiences. Approximately 15% of the students endorsed NSSI. Interpersonal reasons were endorsed proportionally more often for initiating rather than repeating the behavior. Individuals with repetitive NSSI reported significantly lower perceived social support from family members and fewer individuals to seek advice from than single‐act and control participants. Fifty‐nine percent had disclosed their NSSI, but rarely to mental health professionals. Conversations with others about NSSI were rated as being mostly unhelpful. These results emphasize the importance of interpersonal features and functions of NSSI, suggesting treatments should focus on strengthening interpersonal bonds alongside emotion regulation. Improving responses to disclosures of NSSI is needed to promote communication about this behavior and perceived helpfulness of such conversations.     

TO BE FEMALE, MIDDLE CLASS, ANXIOUS, AND BLACK

Women of color theorists have suggested that the double minority status of gender and ethnicity places African American women at higher risk for anxiety. However, little information is available about anxiety disorders among African American women. The existing literature subsumes Black women under the general category of African Americans and focuses on low-income samples. In this study, we examine the manifestation of panic disorder in a sample of 15 predominantly middle-class African American women. We then compare these women to a group of 35 predominantly middle-class African American women without panic disorder on several factors, including presence of isolated sleep paralysis, presence of other anxiety disorders, help-seeking behavior, and victimization. Results indicate that African American women with panic disorder experienced isolated sleep paralysis, and that both groups had high levels of sexual victimization. Help-seeking among women with panic and other anxiety disorders was limited to relationship difficulties, sexual assault, and bereavement.     

Vocabulary Self-Selection: A Study of Middle-School Students' Word Selections from Expository Texts

This study investigated students' decision-making as they self-selected important words from expository texts. Participants were 94 eighth graders and six adult readers. Data sources included students' written responses containing their word selections and reasons for selecting words from eight informational passages, student interviews, and word selections of adult readers. We examined the students' reasons for their word selections and compared their words with those selected by adult readers. Results indicated the following: 1) students of varying reading abilities can self-select important words in an expository passage; 2) students' reasons for selecting words differed from reasons found in related studies; and 3) variability exists across individual students and across adult readers in selecting important words in expository passages.
