Page 10: Participants

More information is needed regarding the participants. How were they selected? Was there any inclusion/exclusion criteria. How did the selection approach affect selection bias?

Also more information is needed on how the schools were selected. What informed the selection of the three districts? How were the five schools selected from the three districts? How are they representative of the target population? Was the school sampling based solely on convenience? What is the sociodemographic of these schools? Are these characteristics of these schools typical of the target population. This information might help contextualize the findings and external validity of the study.

 

 

Hypomania symptoms are time-changing variables and findings should be interpreted with caution, especially because of the nature of the study design and participant population (non-clinical adolescents).

To correctly contextualize and interpret the correlation between the school environment and the study outcomes, better description of the school districts and sociodemographic of the schools and district would be helpful.

Reviewer 2 Report

Comments and Suggestions for Authors

Thank you for the opportunity to review this paper. This is a timely and important issue to explore. The aim of the study was to explore the relationships between bright and dark side hypomania, insomnia, and various dimensions of health-related quality of life (HRQOL), such as self-esteem, family and peer relationships, social acceptance, and autonomy. 

Several comments and suggestions for the authors.

- The authors should standardize the reference list in the text (number with reference in square brackets, not name and year), the manuscript is messy in this respect.

- When was the research conducted (year and time frame not specified)?

- Please provide inclusion and exclusion criteria.

- Can the authors provide the Cronbach’s alpha value for all questionnaires?

- At the beginning of the discussion it is unnecessary to repeat the aim of the research.

- The text of the manuscript should be checked for punctuation, double spaces, etc.

- Research articles usually do not use the word „we”, „our” and regularly use passive verbs.

Reviewer 3 Report

Comments and Suggestions for Authors

Eisenhut at al. present an interesting study here they tried to explore the relationships between bright and dark side hypomania, insomnia, and various dimensions of health-related quality of life (HRQOL) in 1,475 participants in mid-adolescence aged between 11 and 16 years- They could show that  bright and dark side hypomania were associated with a broad, though specific variety of aspects of HRQOL and insomnia.

Minor issues:

1)      In the introduction authors should add the information on the prevalence of bipolar disorders as this disease has the small prevalence of <1% in the global population (and in adolescents lower)

2)      Authors use the classification of Hantouche for dark side and bright side hypomania. The classification sounds very interesting but is very old (2003). Can authors please explain how relevant this classification for the new studies is?
