Abstract
Objectives Our main aim was to identify the factors that may influence consumers’
acceptance of mobile phone caller tunes to increase awareness of consumer reporting of
suspected adverse drug reactions (ADRs). Mobile phone caller tunes — the songs or messages
callers hear — are popular in Africa and Asia but have not been used to aid reporting
of adverse drug reactions (ADRs). We also aimed to evaluate the psychometric
properties of a survey instrument adapted for caller tunes and ADRs.
Methods A cross-sectional survey based on the technology acceptance model (TAM) was
conducted among 486 non-ADR-themed caller tune users and 470 mobile phone users with
no caller tunes in Accra, Ghana. Participants were purposively recruited from voluntary
blood donation sites. After testing the validity and reliability of TAM constructs, a structural
equation modelling approach was used to evaluate the factors that could influence the acceptance
of caller tunes for increasing awareness of consumer reporting of ADRs.
Key findings Perceived usefulness and perceived ease of use had significant positive
effects on consumers’ acceptance of caller tunes for increasing awareness of consumer
reporting of ADRs. However, whereas free of cost had significant positive effects on the
acceptance of caller tunes among those with non-ADR-themed caller tunes (b = 0.15,
P = 0.006), it was not so for those lacking caller tunes (b = 0.05, P = 0.229). The survey
instrument met acceptable validity and reliability criteria.
Conclusions Our findings show that consumers would generally accept caller tunes on
ADRs — if created — to aid consumer reporting of suspected ADRs, but there are
research and practice considerations.
