Bottom Line: Different classifiers are employed to detect potential stress categories and corresponding stress levels.Experimental results show that all the features in the feature space positively affect stress detection, and linguistic negative emotion, proportion of negative sentences, friends' caring comments and teen's reply rate play more significant roles than the rest features.Involving comments and responses under the tweet supplement the detection and improves the detection accuracy of 16.8 %.

ABSTRACT

Background: In the modern stressful society, growing teenagers experience severe stress from different aspects from school to friends, from self-cognition to inter-personal relationship, which negatively influences their smooth and healthy development. Being timely and accurately aware of teenagers psychological stress and providing effective measures to help immature teenagers to cope with stress are highly valuable to both teenagers and human society. Previous work demonstrates the feasibility to sense teenagers' stress from their tweeting contents and context on the open social media platform-micro-blog. However, a tweet is still too short for teens to express their stressful status in a comprehensive way.

Methods: Considering the topic continuity from the tweeting content to the follow-up comments and responses between the teenager and his/her friends, we combine the content of comments and responses under the tweet to supplement the tweet content. Also, such friends' caring comments like "what happened?", "Don't worry!", "Cheer up!", etc. provide hints to teenager's stressful status. Hence, in this paper, we propose to systematically explore the micro-blog feature space, comprised of four kinds of features [tweeting content features (FW), posting features (FP), interaction features (FI), and comment-response features (FC) between teenagers and friends] for teenager' stress category and stress level detection. We extract and analyze these feature values and their impacts on teens stress detection.

Results: We evaluate the framework through a real user study of 36 high school students aged 17. Different classifiers are employed to detect potential stress categories and corresponding stress levels. Experimental results show that all the features in the feature space positively affect stress detection, and linguistic negative emotion, proportion of negative sentences, friends' caring comments and teen's reply rate play more significant roles than the rest features.

Conclusions: Micro-blog platform provides easy and effective channel to detect teenagers' psychological stress. Involving comments and responses under the tweet supplement the detection and improves the detection accuracy of 16.8 %.

Fig3: An example tweet where the red words are negative emotion words, the green ones are categorical words and the orange ones are degree adverbs

Mentions: If no categorical words appear in the clause, we firstly check other clauses in the same sentence, and take the sentence’s categorical words as this clause’s. If the whole sentence does not contain any categorical word, we then check next sentence, and take the next sentence’s categorical words as the clauses. If no categorical words are found throughout the whole tweet, then the stress category will be labeled as “unknown”. Take the example tweet in Fig. 3 as an example, there is no categorical words detected in clause 3 and we estimate the categories by that of clause 1 and 2. Obviously, the categories of clause 3 are academic and interpersonal.Fig. 3
