Measuring an Individual's Tendency to Take Risks: The Risk Propensity Scale1

A new, short, and easily administered Risk Propensity Scale (RPS) is introduced that measures general risk‐taking tendencies. This paper investigates the reliability and discriminant validity of the RPS. The RPS provided scores that yielded a good internal reliability coefficient and adequate test–retest reliability, and the scores correlated moderately to well with those of the Everyday Risk Inventory and the short Sensation‐Seeking Scale. The correlation with the scores from other scales (Need for Cognition scale, Need for Structure scale, and 2 self‐esteem scales) was low to moderate, indicating good discriminant validity. The findings are discussed in relation to risk‐perception research using gambling experiments and in relation to their usefulness for risky decision‐making research.     

Perceptual-cognitive skills and performance in orienteering

The goal was analysis of the perceptual-cognitive skills associated with sport performance in orienteering in a sample of 22 elite and 17 nonelite runners. Variables considered were memory, basic orienteering techniques, map reading, symbol knowledge, map-terrain-map identification, and spatial organisation. A computerised questionnaire was developed to measure the variables. The reliability of the test (agreement between experts) was 90%. Findings suggested that competence in performing basic orienteering techniques efficiently was a key variable differentiating between the elite and the nonelite athletes. The results are discussed in comparison with previous studies.     

Differentiating visual and kinesthetic imagery in mental practice.

Through two experiments, the study sought to emphasize the usefulness of the visual and kinesthetic imagery in mental practice. In Experiment 1, it was hypothesized that when the task to be learned through mental practice necessitates the reproduction of a form by drawing, the visual image, which provides a wide span of apprehension, is more suitable than the kinesthetic image. On the other hand, the kinesthetic image that supplies inputs from the muscles' positions and movements should be more appropriate for the acquisition of the duration of the drawing. In Experiment 2, it was hypothesized that the task, transformed into a motor task necessitating minute coordination of the two hands, would benefit more from kinesthetic imagery. To have optimal control over what was actually experienced during mental practice, the participants' imagery skills were measured. The participants also benefited from prior imagery training. The results demonstrate that when using mental practice to initially acquire a task, visual imagery is better for tasks that emphasize form while kinesthetic imagery is better for those tasks that emphasize timing or minute coordination of the two hands.     

Social Influence in Personally Relevant Contexts: The Respect Attributed to the Source as a Factor Increasing Smokers’ Intention to Quit Smoking1

The study examined the effects of the status of the source in personally relevant persuasion contexts. Smokers (N= 117) with either weak or strong identity as smokers were exposed to an anti‐smoking message, targeting either the tobacco industry or smokers, and attributed either to a health institute or a neighborhood association. The main dependent variable was the change in intention to quit smoking. As expected, the neighborhood association was considered more respectful of the freedom of choice of the target than was the health institute. In high personal relevance conditions (i.e., participants with strong identities as smokers and message explicitly targeting smokers), smokers strengthened their intention to quit smoking when the source was the neighborhood association, but decreased it when the source was the health institute. Implications for health campaign implementation are discussed.     

Teammates On and Off the Field? Contact With Black Teammates and the Racial Attitudes of White Student Athletes1

The intergroup contact hypothesis holds that proximate, cooperative interactions on an equalized basis between Blacks and Whites can minimize Whites’ prejudice (Allport, 1954). This experiment investigated the effect of contact between White and Black high school teammates on White student athletes’ racial attitudes. Using the 1996 Social and Group Experiences (SAGE) survey (created by the authors and administered in the Fall of 1996) commissioned by the National Collegiate Athletic Association, the results indicated a significant relationship between amount of contact with Black teammates in high school and racial policy support and affect, depending on the type of sport played. White student athletes playing team sports who had higher percentages of Blacks as high school teammates expressed more policy support for and greater positive affect toward Blacks as a group than did their counterparts playing individual sports. The role of athletic experiences in changing racial attitudes is discussed.     

Stress and Coping Among Displaced Bosnian Refugees: An Exploratory Study

Traumatic experiences associated with the recent war in Bosnia (1992–1995) have impacted the lives of many Bosnian refugees and displaced people. Approximately 25% of Bosnians were forced to leave their homes and resettle in other areas of Bosnia or abroad. In this study, 82 displaced Bosnians living in the area of Tuzla, Bosnia, and 53 refugees living in the San Francisco Bay area completed the same questionnaire in the Bosnian language. The study describes war-related stress and the association of marital status, anxiety, depression, and sensitivity levels. Furthermore, being single, having lower anxiety ratings, finding and adapting to a new environment easily, and moving on with their lives indicated better self-reported health. Findings also revealed that being divorced or separated, better self-reported health, and lower anxiety, depression, and sensitivity ratings were predictors of more effective coping.     

Desirability of control: psychometric properties and relationships with locus of control,personality, coping,and mental and somatic complaints in three Dutch samples

Desire for control (DC) or need for control has frequently been proposed as an important personality characteristic and as a possible crucial moderator within the fields of achievement, psychological adaptation, stress, and health. However, unlike locus of control, hardly any effort has been undertaken to assess the construct. An exception is the work of Burger and Cooper on the Desirability of Control Scale ( 1979 ). In the present study, the psychometric properties of a Dutch version of the DC scale were tested in three different samples (total N = 1044). Furthermore, relationships between DC, its subscales, and various psychological personality and outcome measures were examined. The results show that the psychometric properties of the original DC scale could be successfully transposed to the Dutch version. Furthermore, factor analyses (PCA) led to the construction of three reliable subscales: ‘control others’ (desire to be in charge of and control others), ‘control self’ (desire to control one's own life), and ‘relinquish control’ (desire to leave others in control). The pattern of relationships with convergent and outcome variables supports the interpretation of these subscales. For ‘control others’, as for the total DC scale (i.e. a total of all 20 items), the emphasis of these relationships was on dominance, active coping, and psychological adjustment. ‘Control self’ was mainly related to self‐sufficiency and independence, while ‘relinquish control’ was clearly associated with passive coping and poor psychological adjustment. In summary, the DC scale appears to be a psychometrically sound instrument to assess desire for control and its subdimensions. Copyright © 2002 John Wiley & Sons, Ltd.     

Statistical inference of minimum rank factor analysis

For any given number of factors, Minimum Rank Factor Analysis yields optimal communalities for an observed covariance matrix in the sense that the unexplained common variance with that number of factors is minimized, subject to the constraint that both the diagonal matrix of unique variances and the observed covariance matrix minus that diagonal matrix are positive semidefinite. As a result, it becomes possible to distinguish the explained common variance from the total common variance. The percentage of explained common variance is similar in meaning to the percentage of explained observed variance in Principal Component Analysis, but typically the former is much closer to 100 than the latter. So far, no statistical theory of MRFA has been developed. The present paper is a first start. It yields closed-form expressions for the asymptotic bias of the explained common variance, or, more precisely, of the unexplained common variance, under the assumption of multivariate normality. Also, the asymptotic variance of this bias is derived, and also the asymptotic covariance matrix of the unique variances that define a MRFA solution. The presented asymptotic statistical inference is based on a recently developed perturbation theory of semidefinite programming. A numerical example is also offered to demonstrate the accuracy of the expressions.This work was supported, in part, by grant DMS-0073770 from the National Science Foundation.     

Persuasive constraint and expert versus non‐expert influence in intention to quit smoking

In a 2 × 2 design, after listing important personal reasons for smoking, 70 smokers were randomly told either that they had sufficient reasons for smoking (low internal constraint to change) or that they did not have sufficient reasons (high internal constraint to change) and were exposed to an anti‐smoking message from a source with either expert (high external constraint to change) or non‐expert (low external constraint to change) status. The main dependent variable was change in intention to give up smoking. The analyses revealed the predicted interaction between external and internal constraint: High internal constraint increased non‐expert influence but not expert influence. Supplementary analysis showed that, when internal constraint was high, non‐expert influence was related to the perceived quality of the message whereas when internal constraint was low, expert influence was related to the source's perceived motivation to inform, i.e. rather than to convince. These results were predicted on the basis of the link that targets establish in social influence settings between constraints to change that are internal (i.e. related to their personal beliefs, feelings or attitudes) and those that are external (i.e. related to the characteristics of the persuasive communication such as the status of the source).

Team climate,climate strength and team performance. A longitudinal study

We tested the hypothesis that the relationship between team climate and team performance is moderated by climate strength. The study sample was composed of 155 bank branches, and a two‐wave panel design was implemented. We measured four team climate facets (support, innovation, goal achievement and enabling formalization). We obtained two subjective indicators of team performance (ratings provided by team members and by team managers) and a financial indicator of team performance. Seven out of the 12 interaction effects tested were statistically significant and showed the expected sign. When financial team performance was the criterion, only the interaction term was significant. This suggests that only strong climates are related to financial team performance over time.
