Individual Differences in Social Comparison and its Consequences for Life Satisfaction: Introducing a Short Scale of the Iowa–Netherlands Comparison Orientation Measure

Research in social psychology has shown individual variation in the tendency to compare one’s own opinions and abilities with those of other people, raising the question of whether social comparisons are psychological dispositions. To test the empirical validity of this proposition, Gibbons and Buunk (1999) created an instrument, the Iowa–Netherlands Comparison Orientation Measure (INCOM), that measures the tendency to engage in social comparison and captures central aspects of the self and the other. This paper analyzes the reliability and validity of the INCOM scale for the German population and discusses potentials for shortening the instrument for continued use in large-scale population surveys. Interdependencies between psychological and structural characteristics are investigated and consequences for life satisfaction discussed. The results show evidence that individuals systematically vary in their orientation towards social comparison.     

What Factors Influence Marital Satisfaction? Differences Between First and Second Marriages

This study examined differences in marital satisfaction between first and second marriages and how additional factors can help explain satisfaction differences between the marriage types. Participants in first marriages reported higher levels of satisfaction than remarried individuals. Regression analyses demonstrated marriage type to be a moderator of satisfaction in second marriages; as education increased, satisfaction also increased. Length of marriage was found to significantly influence satisfaction in first marriages, but not second marriages. In both first and second marriages, participants currently in counseling reported lower satisfaction scores. The need to understand remarriages' distinct characteristics apart from first marriages is discussed.     

Estimating historic population data for small geographies using census housing information

Historical population data for small geographies (e.g. blocks, block-groups, and census tracts) are not available for periods earlier than 1980. In this research note, we propose a geographically-constrained housing unit method (GHUM) to estimate historic population for small geographies using housing age data available in the 1980–2000 censuses. The GHUM is a two-stage method. The first stage follows a traditional housing unit method and provides initial household and group quarter population estimates for small geographies. The second stage takes advantage of the availability of historic data for larger geographies (e.g. counties, states) to adjust the first stage estimates and to provide final estimates. The GHUM is used to estimate 1940–1990 county population and census tract population in Kentucky. The quality of the population estimates is assessed. A two-sample Kolmogorov–Smirnov test indicates that these estimates are statistically reliable at the 10 % significance level.     

Ambiguity framed

In his exposition of subjective expected utility theory, Savage (1954) proposed that the Allais paradox could be reduced if it were recast into a format which made the appeal of the independence axiom of expected utility theory more transparent. Recent studies consistently find support for this prediction. We consider a salience-based choice model which explains this frame-dependence of the Allais paradox. We then derive the novel prediction that the presentation format responsible for reductions in Allais-style violations of expected utility theory will also reduce Ellsberg-style violations of subjective expected utility theory. This format makes the appeal of Savage’s “sure thing principle” more transparent. We design an experiment to test this prediction and find strong support for such frame-dependence of ambiguity aversion in Ellsberg-style choices. In particular, we observe markedly less ambiguity-averse behavior in Savage’s matrix format than in a more standard “prospect” format. This finding poses a new challenge for the leading models of ambiguity aversion.     

Understanding high school student leaders, i: Predicting teacher ratings of leader behavior

We describe the first stage of a longitudinal research program concerned with the prediction, understanding, and durability of early displays of leadership behavior. The predictability of teachers' ratings of leadership behavior for 242 high school students was explored with respect to predictors from the following construct domains: personality, interests, motivation, behavior, self-rated skills, and academic ability. Results revealed that variables from each construct domain significantly and consistently predicted leadership ratings for as long as 12 months after the collection of the predictor data. In addition, the linear combination of predictors from different domains yielded strong prediction of leadership, with R²s in the .40 range. Evidence also showed that both academic ability and the other measured constructs contributed unique variance to the prediction of leadership behaviors as reported by the teachers. These exploratory findings are discussed in light of a continuing research program designed to develop a more comprehensive understanding of the origin, development, and emergence of adult leadership behavior.
