Background Nowadays, there is an ongoing development in virtual social networks and their application for patients' support, diagnosis, self-care, and education. On the other hand, applying short messages as the easiest, simplest, and cheapest way of presenting information would be helpful in this regard. Thus, in this study the effect of social network and sending short messages was assessed on negative thinking status of women. Methods This was an experimental study with pretest-posttest design performed in 2015. Out of 1165 women in Mohajeran city, 75 were randomly assigned into three groups of social network, short message, and control. The participants received a compact disc containing e-content about reducing negative thoughts. They filled out the Crandell cognition inventory (CCI) before and immediately after the intervention and also one month later for assessing their negative thoughts. A Telegram group was established for the social network group while follow-up short messages were sent for the other intervention group. SPSS V.21 was used for data analysis by paired t test, one way analysis of variance, analysis of covariance and repeated measures tests. Validity (in terms of content and structure) of the questionnaire was confirmed by comments from experts and professors and Bartlett test (KMO = 0.846, p and lt; 0.001); the reliability was confirmed by Cronbach’s alpha coefficient (0.69) and test-retest coefficient (0.928). Results There were significant differences between pretest and posttest scores in social network, short message, and control groups (P value 0.45, 0.001 and lt; 0.001 and lt; respectively). There were also significant differences between pretest and follow-up scores in the abovementioned groups (P value 0.003, 0.012, 0.001 respectively). There was no significant difference in the follow-up scores between three groups (P = 0.917). Conclusions The results showed that multimedia e-content merely would reduce participants’negative thoughts. Therefore, providing multimedia e-content could be beneficial in improving the effectiveness of public health education.
