ABSTRACT Online health research is common during pregnancy, especially if women are facing complications. Given the unpleasant emotions women experience after research, it is surprising that cyberchondria, excessive and repeated online health research caused by anxiety that intensifies such anxiety, has not been studied in pregnant women. Therefore, the aim of this study was to examine the predictors of cyberchondria among women with and without pregnancy complications, accounting for health anxiety (a worry regarding personal health) and pregnancy-specific anxiety (concerns related to pregnancy and childbirth). A total of 360 pregnant women completed a questionnaire consisted of Short Health Anxiety Inventory, Pregnancy Concerns Scale and Short Cyberchondria Scale. The results of one-way MANOVA showed that women who had medically complicated pregnancy had higher levels of health anxiety, pregnancy-specific anxiety and cyberchondria compared to those without complications. A hierarchical multiple regression analysis showed that health anxiety and pregnancy-specific anxiety were predictors of cyberchondria but had different roles depending on complications. Pregnancy-specific anxiety predicted cyberchondria in both groups above health anxiety. Health anxiety predicted cyberchondria only in women without complications. In conclusion, women with complications have a higher chance of experiencing cyberchondria. Pregnancy-specific and health anxiety are risk factors for cyberchondria in pregnant women.
