ABSTRACT
This study aims to investigate the influence of self-review threat, self-interest threat, advocacy
threat, intimidation threat and familiarity threat collectively on auditor’s independence and
objectivity in Lagos State, Nigeria. The method employed for the study was a survey research
design, in which data were collected through a well structured questionnaire instrument. The
population of the study comprised all audit firms in Lagos State, while the Big4 audit firms were
used as sampling frame for the study with convenience sampling technique. A total of 70 copies
of administered questionnaire were returned and analysed for this study. The data was analyzed
using multiple regression analysis. The study reveals that self-interest threat with p-value (0.140), self-review threat with p-value (0.324), advocacy threat with p-value (0.564), familiarity threat
with p-value (0.600), as well as intimidation threat with p-value (0.540) have no significant
influence on auditor’s independence. The study also reveals that self-interest threat with p-value
(0.136), , advocacy threat with p-vale (0.116), and familiarity threat with p-value (0.33), have no
significant influence on auditor’s objectivity, while self-review threat with p-value (0.007) as
well as intimidation threat with p-value (0.002) have significant influence on auditor’s
objectivity. In all, the study concludes that ethical threats have significant effect on auditor’s
objectivity. It was therefore recommended that engagement partners should have enough respect
for their own reputations and careers to encourage objectivity and effective use of safety
measures.
