Poor quality emails are causing almost as much stress in the workplace as the number received, a psychological study has revealed.

According to the study of 218 staff from the University of Queensland, respondents found interpreting ambiguous emails can be just as stressful as receiving large volumes of messages.

"Complex and emotionally-driven emails may complicate the message and allow room for misinterpretation," said study author and provisional psychologist from New Zealand, Rowena Brown.

Ms Brown will present her PhD findings at the Australian Psychological Society's (APS) 8th Industrial & Organisational Psychology (IOP) Conference at the Novotel Sydney Manly Pacific from 25 to 28 June.

"Our study found poorly crafted and complex emails can contribute to work-related stress, such as feeling overloaded as well as impacting on job satisfaction and working relationships."

"Employees reported that poorly written emails can also create confusion and disagreements over workrelated activities and responsibilities. Feeling stressed, overwhelmed and emotionally exhausted are other common strains caused by emails."

"Interestingly, the study found that large numbers of emails also increased job satisfaction. This may suggest that receiving workplace emails enables users to feel connected and important within their work environment."

"Email is a double-edged sword. We know that email can help employees to feel engaged with and connected to their work colleagues, however the impact of a poor quality email, combined with the expectation to respond immediately, can create unnecessary stress," she said.

"Our research raises important issues for employers, who have a responsibility to train their staff in appropriate email etiquette," said Ms Brown.

About the study: Ms Brown surveyed 218 employees from the University of Queensland. On average participants sent and received 30 emails per day, in addition to spam mail. Future research will examine how emails contribute to conflict in the workplace.

About the IOP Conference: The eighth biennial IOP Conference will explore contemporary issues in workplace psychology such as employee engagement, work/life balance and the impacts of new media. Keynote speakers include: Professors Beryl Hesketh, Deniz Ones, Eduardo Salas, Sabine Sonnentag, Phillip Taylor and Robert Wood.

Ms Brown is available for interview during the week of the conference, and top tips on email etiquette are available on request.
