Table 6 summarizes the results of hypothesis testing. It shows that ICNs are negatively and significantly related to PIN of EVs at p < 0.01. An R2 = 0.67 in Figure 1 indicates that ICNs can explain about 67 per cent of the variance in PIN the EVs. Therefore, H1b is supported. This finding is consistent with that of Follows and Jobber (2000), which found that ICNs are negatively related to PIN. Self-transcendence values (SVN) were found to have a positive and significant relationship with ECNs of purchasing EVs. The positive relationship between SVN and ECN supported H2a, which hypothesized a positive relationship. This is consistent with an earlier finding (Follows & Jobber, 2000) that was significant at p < 0.01. Self-transcendence values (SVN) were found to have a significant and positive relationship with ICNs of purchasing a ‘green’ car (p < 0.05). The positive relationship between SVN and ICN did not support H2b, which hypothesized a negative relationship. This is not consistent with the earlier finding (Follows & Jobber, 2000) that was significant at p < 0.05. Conservation values (CVN) have a positive and insignificant relationship with ECN and ICN. H3a is not supported as it was hypothesized to be a negative relationship. H3b is supported as the relationship between CVN and ICN is positive. Self-enhancement values (SEVN) were found to be positively and significantly related to ECN and ICN (p < 0.01) and negatively related to PIN (p < 0.01); hence, H4b and H4c were supported. H4a was not supported as it was hypothesized to be a negative relationship. Table 5 summarizes the results of the hypothesis testing. This finding is consistent with the findings of Follows and Jobber (2000) and Oliver and Lee (2010).
