Willingness to seek professional help for a serious emotional problem and feeling comfortable talking about personal problems with professionals were significantly associated with future help seeking and treatment use. One-third (33.4%) of participants who stated at baseline that they would "definitely go" to a professional if they had a serious emotional problem sought future help, compared with 20.7% of those who would "definitely not go." Corresponding values were 33.4% and 24.4% for those who reported feeling "very comfortable" and "not at all comfortable," respectively, talking about personal problems with a professional. The associations were consistent among participants with and without a history of help seeking and with and without mood, anxiety, or substance use disorders during the follow-up. Embarrassment if friends found out and beliefs about treatment effectiveness were not associated with future help seeking or service use.
