Self Interest Vs Self Review Threat

Hi there,

I was of the perception that ‘Temporary Staff Assignment’ is regarded as a Self-Review Threat.

However, in BPP’s textbook (Page 61) ‘Temporary Staff Assignment’ is found under Self-Interest Threat.

I was just wondering whether this is a type error in BPP’s textbook, or whether I have interpreted it wrongly and should thus be classified as a Self Interest threat.
