Why the adult picture does not transfer
The first half of this post is about developmental difference, and an answer that recites the adult depression criteria has missed it. In children and younger adolescents mood disorder often presents as irritability rather than reported sadness — the diagnostic criteria themselves permit irritable mood in place of depressed mood for this age group — alongside somatic complaints such as headache and abdominal pain, school refusal, a fall in academic performance, social withdrawal, and changes in sleep and appetite that a parent notices before the child names anything. Younger children have limited vocabulary for internal states, so the history comes from multiple informants and the presentation is behavioural. Bipolar presentation deserves its own paragraph because it is the differential that changes management most: elevated or expansive mood, decreased need for sleep without daytime fatigue, and grandiosity are what distinguish it from the irritability of unipolar depression or of a disruptive behaviour disorder.
The treatment half should be organised by evidence rather than by modality list. Psychotherapy is first-line for mild to moderate presentations — cognitive behavioural therapy and interpersonal therapy for adolescents both have trial support — with medication added for moderate to severe illness or when therapy alone has not worked. Name which agents carry paediatric approval rather than listing antidepressants generally, and address the boxed warning on suicidality in under-25s directly, because avoiding it looks like not knowing it: the evidence supports treating, with informed consent and close early monitoring, rather than withholding treatment. Include the pieces that are easy to omit and are marked — family involvement, school liaison, safety planning and lethal means restriction, and screening for the comorbidity that is more common than not in this population. Two scholarly articles is a floor, and current clinical practice guidelines are the strongest thing you can cite here.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Describe how mood disorder presents differently across childhood and adolescence.
- 02Distinguish unipolar depression from bipolar presentation in young people.
- 03Sequence psychotherapy and pharmacotherapy according to severity and evidence.
- 04Address the suicidality warning and the monitoring it requires.
- 05Incorporate family, school and safety planning into a treatment answer.

Course-wide instructions that accompany this question
ADDITIONAL INSTRUCTIONS FOR THE CLASS Discussion Questions (DQ) Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses. Weekly Participation Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week. APA Format and Writing Quality Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. I highly recommend using the APA Publication Manual, 6th edition. Use of Direct Quotes I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source. LopesWrite Policy For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score. Late Policy The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading. Communication Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.

Guideline sources for paediatric mood disorder
Recommended databases
- StatPearls via NCBI Bookshelf
- American Academy of Child and Adolescent Psychiatry practice parameters
- PubMed
- CINAHL
- Your programme's psychiatric assessment resources
Search sequence
- 1.Confirm the diagnostic criteria wording that permits irritable mood in young people.
- 2.Read a current guideline on adolescent depression treatment sequencing.
- 3.Note which antidepressants carry paediatric indications and at what ages.
- 4.Read the current evidence on the suicidality warning and monitoring intervals.
- 5.Find two scholarly articles you can cite for specific claims, not for background.
Reference shortlist
These are authoritative starting points, not a ready-made bibliography. A qualified reviewer must confirm that each source fits the assignment and supports the claim beside which it is cited.
Nothing here is cleared for citation until you have read it.

Review before submission
Common mistakes
- Applying adult depression criteria without the irritability substitution.
- Omitting somatic and behavioural presentations, which is how younger children present.
- Ignoring bipolar disorder as a differential that changes management.
- Listing modalities instead of sequencing them by severity.
- Avoiding the suicidality boxed warning rather than addressing it.
- Leaving out family involvement, school liaison and safety planning.
Submission checklist
- Irritability as a presenting mood is stated explicitly.
- Presentation is differentiated by developmental stage.
- Bipolar disorder appears as a differential.
- Treatment is sequenced rather than listed.
- The suicidality warning and monitoring plan are addressed.
- At least two scholarly articles are cited in APA format.
