The present study investigated the effect of optimistic bias on help-seeking intentions and behaviors in relation to health care professionals and nonprofessionals for depressive symptoms. In addition, the study tested the hypothesis that seeking help from professionals poses a greater threat for self-esteem than from non-professionals. A questionnaire survey (N = 462) using clinical vignettes was conducted with university students. The results suggested that optimistic bias had an impact on help-seeking intentions and behaviors directed towards both health care professionals and nonprofessionals. There seemed to be a relatively stronger threat to self-esteem in help-seeking involving nonprofessionals and a weaker threat in help-seeking involving professionals, contrary to previous studies. The results were explained by the threat to self-esteem and equity theories. Understanding the rationale of optimistic bias and symptom recognition in the help-seeking process may provide relevant information to bridge the service gap in the treatment of depression.
