The study conducted reliability analysis using Cronbach’s alpha for each multi-item scale. Table 2 shows the results, with six out of eight factors having alpha values greater than 0.6, meeting the reliability standard. Cronbach’s alpha was not applicable for two factors (Legal concern and IT Outsourcing) as they each had a single item. Overall, the reliability coefficients ranged from 0.61 to 0.8079, indicating acceptable reliability.

Hypotheses Testing
Impact of Reliability on OSS adoption
Hypothesis 1: IT Outsourcing Organizations serviced by Indian IT service providers that perceives OSS to be reliable will significantly adopt OSS.
The impact of Reliability on OSS adoption was assessed using multiple regression tests and results are presented in table 3 below.
Model | Unstandardized Coefficients | Adjusted R Square | F Change | t | Sig. | ||
Beta | Std. Error | ||||||
1 | (Constant) | 1.441 | .460 | .023 | 12.276 | 3.135 | .002** |
Reliability | .520 | .148 | 3.504 | .001** | |||
2 | (Constant) | 1.833 | .486 | .032 | 5.610 | 3.767 | .000 |
Reliability | .545 | .148 | 3.681 | .000*** | |||
Client Organization Size | -.130 | .055 | -2.368 | .018* | |||
Dependent variable: What is the extent of OSS adoption at client?
Significance: *p < .05, **p < .01, ***p < .001
Table 3 of the multiple regression analysis shows that the beta coefficient for OSS adoption on Reliability is highly significant (beta=0.520, t=3.504, p=0.001). When Client Organization Size is added as a control variable, its effect is also significant (beta=-0.130, t=-2.368, p=0.018). With an R-square of 0.032, the results reject the null hypothesis and support the alternative hypothesis, indicating a significant association between Reliability and OSS adoption.
Convergent validity ensures that items representing a construct share a high proportion of variance. Individual item reliability was assessed by examining the weight and loading of each item on its construct. All indicator weights were found to be significant, supporting the inclusion of all indicators.
As per Table 4, Composite Reliability (CR) and Reliability statistics were greater than the recommended cut-off 0.70. The Average Variance Extracted (AVE) was above the 0.50 threshold with the exception of OSS Support Availability (OSSSUP), which was 0.460. However, since OSSSUP showed minimal correlation with other factors, and its Cronbach’s alpha (0.606) and Composite Reliability (0.706) were adequate, it was retained. These results support convergent validity.
Construct | Average Variance Extracted (AVE) | Composite Reliability (CR) |
Reliability (RELIB) | .617 | .820 |
License concern (LICNSE) | .828 | .906 |
Legal concern (LEGAL) | 1 | 1 |
Software cost (SWCST) | .639 | .826 |
Management support (MGTSUP) | .609 | .854 |
IT Outsourcing (ITOUTG) | 1 | 1 |
OSS Support availability (OSSSUP) | .458 | .709 |
IT Service provider (SWVEN) | .714 | .882 |
Client Organization Size (SIZE) | 1 | 1 |
OSS Adoption at Client (OSSADP) | 1 | 1 |
Discriminant validity was assessed by ensuring the square root of the Average Variance Extracted (AVE) was higher than all inter-construct correlations, as shown in Table 5. Additionally, cross-loadings were examined, with results in Appendix C-4 confirming that each item loads higher on its intended construct than on others. Both tests indicate the model meets the required level of discriminant validity.

The diagonal values representing the square root of the Average Variance Extracted (AVE)
A structural model was used to examine the linear regression effects of endogenous constructs, assessing path coefficients (β), path significance (p-value), and explained variance (R²) through PLS. A bootstrapping procedure of 5000 resamples with a one-tailed t-test for significance was implemented in the analysis. The theoretical, control, and full models were estimated. Results showed that the R² for OSS adoption was significant across all models. The full model explained significantly more variance than the theoretical model at 95.6% variance explained with highly significant F-statistics (p < 0.001), signifying that the model explains OSS adoption better.
