Using individual (not summated) Likert-type items (questions) as measurement tools is common in agricultural education research. The Journal of Agricultural Education published 188 research articles in Volumes 27 through 32. Responses to individual Likert-type items on measurement instruments were analyzed in 95, or more than half, of these articles. After reviewing the articles analyzing individual Likert-type items, 5 1 (54%) reported only descriptive statistics (e.g., means, standard deviations, frequencies/percentages by category). Paired Likert-type items or sets of items were compared using nonparametric statistical techniques (e.g., chi-square homogeneity tests, Mann-Whitney-Wilcoxon U tests, Kruskal-Wallis analysis of variance tests) in 12 (13%) of the articles. Means for paired Likert-type items were compared using parametric statistical procedures (e.g. t-tests or analysis of variance F-tests) in 32 (34%) of the articles.

Three studies were conducted to measure the antecedents of women's attitudes toward men using the integrated threat model. Four types of threats were hypothesized to produce negative attitudes toward men: (1) realistic threat based on threats to women's political and economic power, (2) symbolic threat based on value differences, (3) intergroup anxiety experienced during social interaction with outgroup members, and (4) negative stereotypes of men. Negative contact was hypothesized to increase the perception of all four threats as well as to affect attitudes directly. The findings suggest that symbolic threat, intergroup anxiety, and negative contact are the strongest predictors of negative attitudes toward men. Contrary to expectation, realistic threat may not be important to women's attitudes toward men.

This set of two studies employed the integrated threat theory to examine attitudes toward affirmative action (AA). The first study found that opposition to the policy of AA was predicted by realistic threats, symbolic threats, and personal relevance; while attitudes toward the beneficiaries of AA were predicted by three of the four threat variables (symbolic threats, intergroup anxiety, and negative stereotypes), and in-group identity. The second study replicated and expanded on the first study and found that the effects of several individual-difference variables (racism, antiBlack affect, and political conservatism) on opposition to AA were mediated by three of the threats in the integrated threat theory (realistic threats, symbolic threats, and negative stereotypes). The implications of the results are discussed.For over 30 years, affirmative action has been one of the most controversial social policies of our times. Opponents question whether or not affirmative action is needed or necessary and whether it violates the norm of meritocracy (fairness) that is so dear to many Americans. Many opponents view affirmative action as offering preferential treatment to its beneficiaries while creating reverse discrimination for nonbeneficiaries of affirmative action. Proponents, on the other hand, suggest that affirmative action assists the achievement of women and minorities, and provides female and minority role models. Proponents also view affirmative action as helping to remedy past discriminatory practices, offsetting current discrimination, and increasing diversity in the workplace.Overall, Americans tend to support the idea of equal opportunity, yet there is widespread opposition to affirmative action (Kinder & Sanders, 1 The authors thank Cookie Stephan for her comments on an earlier version of this manuscript; Larry Gregory and Douglas Gillan for serving as statistical consultants; and the anonymous reviewers for their helpful comments.

In agricultural education, both 4-H and FFA have identified leadership development as central to their mission. Many Cooperative Extension Service and agricultural educators, members, and alumni think these organizations provide effective leadership programming. However, there is little research to support that viewpoint. The purpose of this study was to develop a valid, reliable scale to measure youth leadership life skills development. The first phase involved the conceptualization and operationalization of youth leadership life skills development (YLLSD). YLLSD was conceptualized as having seven sub-domains (Miller, 1976) and operationalized with 68 indicators. Each indicator used a four point Likert-type subscale. Face and content validity were assessed by a panel of experts. In the second phase, construct validity, reliability, and dimensionality were assessed. Data were collected during September and October, 1992, following the Dillman procedure. The target population was 6,388 senior 4-H and FFA members from New Mexico. A random sample of 400, stratified proportionally to ensure organizational representation was generated. A usable return rate of 66% was obtained. No differences were found between respondents and nonrespondents. During construct validity assessment, indicators of youth leadership life skills development were eliminated through item analysis, internal structure relationships, and cross-structure relationships. The final summated scale of 30 indicators had a Cronbach's alpha reliability coefficient of .98. Factor analysis was used to assess dimensionality. Although the final scale contains indicators from the seven original conceptual domains, youth in the study perceived the construct to be unidimensional.
