track assistant, associate, and full professors employed in 12 departments in each of six prominentCanadian universities. To ensure that the chosen departments were typical in terms of paradigmdevelopment, universities with very active research profiles, determined by grant and contractawards, were chosen. In total, approximately 2201 questionnaires were distributed and 649 werereturned for a response rate of 29%. By university, response rates ranged from 25% to 38%. Bydiscipline, response rates ranged from 22% (math) to 40% (geology and anthropology). As therewere no significant demographic differences across universities, and across the pattern ofintercorrelations among variables within each university, the data were combined and examinedas a single sample. The average age of this sample was 48.28 years, with 92% male respondents.Ninety percent of the sample indicated that they were tenured, with 60% at the rank of fullprofessor, 30% at the rank of associate professor, 9% at the rank of assistant professor, while theremaining two percent responded as belonging to the “other” category. As there were norespondents from three departments, 69 departments were available for group-level analyses. Thenumber of respondents from each department ranged between 2 and 21, with an average of 9.07.MeasuresDepartment conflict. Perceived conflict within a respondent’s academic departmentwas measured with Rahim’s (1983) eight-item intragroup organizational conflict scale. For eachitem, the word group was replaced by the word department. Although Rahim’s scale assumesconflict to be unidimensional, later literature (Jehn, 1995; 1997) suggests the presence of threedistinct types of conflict: task, relationship, and process. As a result, an exploratory factoranalysis was conducted to discern the dimensionality of our measure of conflict. Correspondingclosely to Jehn’s descriptions of the nature of conflict, four items (e.g., “there is friendlinessamong members of my department,” reverse coded) were found to load on a factor which welabeled relationship conflict, three items (e.g., “there is difference of opinion among members ofdepartment”) loaded on a second factor labeled task conflict, and one item (“we have lots ofbickering over who should do what job”) loaded on the third factor, labeled process conflict.Support for these exploratory findings was determined by comparing three models usinga confirmatory factor analysis (CFA): single factor, correlated two-factor, and a correlated threefactormodel of conflict. An examination of the overall fit indices indicated that the correlatedtwo-factor model (χ² = 71.81, df = 13, CFI = 0.98, NFI = 0.97, NNFI = 0.96, RMSEA = 0.09) fitthe data better than the single factor model (χ² = 207.42, df = 20, CFI = 0.93, NFI = 0.92, NNFI =0.90, RMSEA = 0.12) and the correlated three-factor model (χ² = 107.22, df = 17, CFI = 0.97,NFI = 0.97, NNFI = 0.94, RMSEA = 0.09). All items in the two-factor model had significantfactor loadings. The internal consistency reliabilities of the relationship and task conflict subscaleswere .88 and .77 respectively, with a zero-order correlation of .70 at the individual level.Based on these findings, two dimensions of conflict, task and relationship, were examined in allsubsequent analyses.To justify aggregation at the department level, we examined within-group agreement ondepartmental task and relationship conflict for each department in our sample using James,Demaree, and Wolf’s (1984) estimation approach (r wg ). For departmental relationship conflict,the median r wg was .70, while that for departmental task conflict was .60, with 50% of thedepartments having values of r wg greater than .60 on both measures. While these estimates maybe less than optimal, they must be examined in light of the reduced number of items in eachmeasure (James et al., 1984). Nevertheless, an ANOVA test (cf. George & Bettenhausen, 1990)suggests that there are discernable between-department differences in relationship conflict (F =2.93, p
politics (cf. Johns 2001; Rousseau & Fried, 2001). Respondents described their department’spractices regarding each activity (e.g., promotion decisions, curriculum design) on a five-pointscale ranging from not at all political to extremely political. A factor analysis confirmed aunidimensional structure, with item loadings ranging between .57 and .80, and an internalconsistency reliability of .92. As this measure was to be used at the group level, we employedJames et al.’s (1984) estimate of within-group agreement. The median r wg was .93, withapproximately 95% of departments having values greater than .60.Paradigm Development. Paradigm development ranks were assigned to academicdepartments and their corresponding members based on rankings obtained from previous primaryresearch (see Lodahl & Gordon, 1972; Salancik, Staw, & Pondy, 1980; Pfeffer & Moore, 1980).Paradigm development was indexed as the average rank of the twelve academic departmentscommon to Pfeffer and Moore (1980) and Salancik et al. (1980), excluding biology, whichexhibits an unstable ranking. The rank order assigned to the twelve departments studied here(from lowest to highest paradigm development) is: sociology (ranked 1); political science;history; anthropology; geology; economics; psychology; chemistry; mechanical engineering;physics; electrical engineering; mathematics (ranked 12).Role ambiguity and role conflict. Six items, adapted from Rizzo, House, and Lirtzman(1970), were used to measure role ambiguity. Respondents were required to indicate the extent towhich they agreed with each statement, using a 7-point Likert-type scale ranging from 1 =disagree strongly to 7 = agree strongly. The internal consistency reliability estimate for thismeasure was .78. Role conflict was also measured using eight items from Rizzo et al. (1970),which had an internal consistency reliability of .84.Rank heterogeneity. We used Blau’s (1977) heterogeneity index to measure rankdiversity for each department. Information on rank composition was obtained by consulting eachuniversity’s annual calendar. As our sample comprised individuals at the assistant, associate, orfull professor rank, we counted the number of faculty in each of these three rank categories only.As two departments within a single university did not organize their faculty list by rank, we couldnot compute measures of heterogeneity for these departments.Control variables. Department size and demographic variables such as age, gender, andyears in department were controlled because these variables have been found to be associatedwith perceptions of politics (e.g., Madison, Allen, Porter, Renwick, & Mayes, 1980; Anderson,1994; Ferris, Frink, Bhawuk et al., 1996; Ferris & Kacmar, 1992). A measure of department sizewas created by obtaining information from annual university calendars. The measure reflectedthe number of faculty from the three ranks listed previously. As departmental task andrelationship conflict measures varied across universities, it was necessary to control for universitywhen examining associations involving either of these variables. Five dummy coded vectorswere formed to signify membership in a university, and individuals and departments were bothassigned a value of 1 or 0 because many hypotheses involved cross-level associations.Discriminant validity. To ensure that our self-report measures of role ambiguity, roleconflict, department conflict, and politics assess different constructs, we conducted a principalcomponents factor analysis . Results of a four-factor, rotated solution confirmed the distinctnessof these measures, with items loading on their respective factors (see Appendix A).ResultsTables 1 and 2 present descriptive statistics and correlations for variables at theindividual and department levels. At the individual level (Table 1), age, rank and years indepartment are highly and positively associated with each other. As expected, role ambiguity and41
