An exploration of the strengths and weaknesses of using text messaging as a tool for self-report data collection in psychological research

Short Message Service (SMS) has immense potential for self-report data collection because it makes use of mobile phones that people already own, and allows researchers to communicate with participants regardless of physical location. Though interest in the possibilities of SMS as a tool for psychological research is slowly growing, to date, there has been no structured investigation of how this potential may be applied in psychological research. The research within this thesis examined the feasibility of using SMS as a tool for self-report psychological research, focussing on its strengths and weaknesses as a research mode. Across fifteen studies, this was investigated using a mixture of literature review, meta-analysis, surveys, and interviews. Participant samples varied from the broad (general population, university students) to specific (the elderly, the deaf). Strengths of SMS as a tool for self-report psychological research included growing interest in research community; positive perceptions of SMS as a research tool amongst potential sample; prompt responses and high response rate; suitability for frequent repeated sampling; and usefulness as a reminder prompt to support other modes of data collection. Weaknesses included a disconnect between stated willingness to participate and actual participation; response incompleteness; unsuitability for infrequent sampling; and some problems with psychometric equivalence in relation to other research modes like online or paper surveys. This was the first structured evaluation of SMS as a tool for self-report data collection in psychological research. Conclusions are limited by somewhat arbitrary design choices (such as the psychological topic within surveys) made in the absence of guiding background literature. Future research can refine these choices and use the logic presented here to guide further investigation into how SMS performs with more varied samples, different psychological topics, and as part of different research designs. This research has shown that while SMS has great potential as a tool for psychological self-report research, it has a number of weaknesses. Identifying these strengths and weaknesses, and some design choices which may mitigate the weaknesses, will open up possibilities for a wide range of future psychological research
