ANALYSIS AND RESULTS Assessing the Coopetition Scale The proposed coopet1tlon scale was evaluated using a three-step approach. First, exploratory factor analysis (EF A) was employed for classifying the items to reflect the underlying structure of the construct. Second, confirmatory factor analysis (CF A) was employed to determine the acceptability of the data. Finally, the reliability of the scales measuring each of the identified factors or dimensions was examined. Exploratory factor analysis is a useful preliminary technique for scale construction, and is used to purify items. Before the analysis, Kaiser Meyer Olkin (KMO) and Bartlett's Test of Sphericity were used to determine if the correlation matrix is appropriate for factoring. A KMO of .92, exceeding the .60 level suggested by Gursoy and Gavcar (2003), and a Bartlett's Test of Sphericity with p<.001 together indicate that factor reduction by exploratory factor analysis can be applied to the data (see Table 2). Principal axis factoring, rather than components analysis, was used as a variable reduction method. Principal axis analysis seeks the least number of factors which can account for the common variance of a set of variables. Principal component analysis should not be used if a researcher wishes to obtain parameters reflecting latent constructs or factors (Widaman, 1993). Items with a> .50 extraction value were eliminated (see Table 3). The final results produced an 11- item scale. In the new scale, mutual benefit is represented by three items (MB 1, MB2, MB7), trust by three items (Tl, T2, T4) and commitment by five items (COM!, COM2, COM3, COM4, COM5).

The overall chi- square statistic was (41)=316.08, p=.000. However, the analysis was conducted with a large sample, and chi-square values will be higher as sample size increases (e.g., see Kelloway, 1998). Widely used fit indices exceeding .90, and .87 when adjusted for degrees of freedom (AGFI), indicate an adequate fit [Goodness-of-Fit Index (GFI) =.92; Comparative Fit Index (CFI) =.96; Normed Fit Index (NFI) =.95; Non-Normed Fit Index (NNFI) =.95]. The Root Mean Square Error of Approximation (RMSEA=.10) was at a level supported by Steiger (1990) and the Root Mean square Residual (RMR=.03) was lower than the recommendedlevelof.05. 47 Items Extraction T3 .346 T4 .712 T5 .279 T6 . 288 COMl .668 COM2 .712 COM3 .675 COM4 .373 COM5 .747 COM6 .675 The results of the CF A are summarized in Table 4. Items loaded on their respective dimensions and all maximum likelihood estimates (MLE' s) were >. 70 and highly significant (p's<.001) (the lowest t-value was 26.50 for COM5).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
