Social Media and Children’s Mental Health
Seven sources. Four primary. Three secondary. APA format. Discussion questions on top of that. This guide breaks down exactly what each part requires — and how to approach the sources you already have, the ones you still need to find, and the three reflection questions that most students underestimate.

Get Expert Help →What an Annotated Bibliography Actually Is — and What It Is Not
An annotated bibliography is a list of sources formatted in APA style, where each citation is followed by a short paragraph — the annotation — that you write in your own words. It is not a list of abstracts. It is not a summary of what you read. It is your evaluation of each source: what it argues, whether it is credible, how it connects to your thesis, and what it adds to the conversation. Those are four different things, and strong annotations address all of them.
A lot of students make one mistake right out of the gate: they copy the abstract from the article, change a few words, and call it an annotation. That is not an annotation. It is also the kind of thing that shows up clearly on Turnitin. The annotation has to be your reading of the source — what it found, whether you trust how it found it, and why it matters for your argument about social media and children’s mental health.
This assignment has two distinct parts that require different kinds of writing. The annotated bibliography itself is analytical and source-specific. The discussion section — the three reflection questions — is where you zoom out and think across all your sources together. Most students spend all their time on the citations and rush the discussion. Flip that instinct. The reflection questions are where your grade lives.
What This Assignment Has Three Moving Parts
Citation · Annotation · Reflection — each requires different writing
Your Source Map: What You Already Have vs. What You Still Need
You are not starting from scratch. The assignment gives you three sources to use, and your thesis statement already includes a fourth. Here is how they map against the 7-source requirement — and what classification each source likely falls under.
Source Inventory: 4 in Hand, 3 Still Needed
Total required: 7 sources · 4 primary · 3 secondary
Wang, W. (2024). Short-form videos on social media — positive and negative impacts on adolescent wellbeing. SHS Web of Conferences, 199.
Interview-based original study → likely primary sourceShoshani, A., Kor, A., & Bar, S. (2024). Longitudinal study of COVID-era social media use on psychiatric symptoms in 3,697 children aged 8–14. European Child & Adolescent Psychiatry, 33(11).
Original longitudinal data collection → primary sourceChukwuere, J. E., & Chukwuere, G. C. J. (2024). Psychological factors behind social media addiction in youth — mini literature review. African Journal of Sociology, Psychology and Rural Studies, 4(2).
Mini literature review = reviews other studies → secondary sourceHopkins Medicine. (n.d.). Social media and mental health in children and teens. Johns Hopkins Medicine.
Health information page synthesizing research → secondary sourceSource 5 — still needed. Should be an original research study (survey, clinical study, experiment) with direct data on children and social media use.
Find in PubMed, PsycINFO, or Google ScholarSource 6 — still needed. Another original research study. Consider a study focused on a specific platform (TikTok, Instagram) or a specific outcome (anxiety, sleep disruption).
Aim for publication within last 5 yearsSource 7 — still needed. A government report, policy document, systematic review, or reputable health organization resource. The 2023 U.S. Surgeon General Advisory already mentioned in your thesis is a strong candidate.
HHS, CDC, AAP, Surgeon General’s office are all credible secondary sourcesClarify Your Source Count Before You Start Writing
The assignment specifies 4 primary and 3 secondary. You currently have a strong case for 2 primary (Wang, Shoshani et al.) and 2 secondary (Chukwuere mini-review, Hopkins Medicine). That means you still need 2 more primary sources and 1 more secondary source. Confirm with your instructor whether the Hopkins Medicine page counts, since it is a health information website rather than an academic publication — some instructors require all sources to be peer-reviewed. If it does not count, you may need 3 more sources total.
Primary vs. Secondary Sources: What the Difference Actually Means Here
This distinction trips people up because the definitions shift depending on the field. In history, a primary source is something written at the time of the event. In social science research — which is what this topic falls under — the distinction is about where the data comes from.
Primary Sources
Original data · First-hand researchA primary source in social science research presents original data collected directly by the researchers. They ran the study. They collected the numbers. They are reporting their own findings for the first time.
- Survey-based studies measuring depression or anxiety scores in adolescents
- Longitudinal studies tracking social media use over time
- Interview-based qualitative research with youth participants
- Clinical trials or experimental studies on screen time effects
- Original epidemiological research on social media and mental health outcomes
Secondary Sources
Synthesis · Review · PolicyA secondary source analyzes, summarizes, or interprets research done by others. It does not present new data — it makes sense of existing data from multiple studies or presents synthesized expert guidance.
- Systematic reviews and meta-analyses of multiple studies
- Literature reviews (like the Chukwuere mini-review)
- Government health advisories and policy reports
- Health information pages from hospitals or medical organizations
- Textbook chapters and edited academic volumes
The Gray Area: Meta-Analyses
Meta-analyses collect data from many primary studies and run new statistical analyses on that pooled data. Technically they generate new findings — but from existing studies, not new participants. Different instructors classify them differently. If you use a meta-analysis on social media and adolescent mental health, note in your annotation that it is a meta-analysis and let your instructor tell you how they want it classified if it matters for your source count.
Anatomy of One Strong Annotation
Every annotation in this bibliography needs to do three things — and they need to happen in order. A lot of annotations only do the first one. That is why they score low.
What Every Annotation Must Include
150–200 words per source · Write in your own words · Third person preferred
Strong vs. Weak Annotation — Side by Side
The annotation is not proof that you found a source. It is proof that you read it carefully enough to evaluate it. That is a completely different thing.
APA 7th Edition Format for Each Source Type You Are Working With
APA 7th edition is the current standard. Here is the exact format for the source types in this bibliography — with examples based on sources already in your assignment.
▸ Format:
Last, F. M., & Last, F. M. (Year). Title of article in sentence case. Journal Name in Title Case and Italics, Volume(Issue), page–page. https://doi.org/xxxxx
▸ Example (Shoshani source):
Shoshani, A., Kor, A., & Bar, S. (2024). [Full article title]. European Child & Adolescent Psychiatry, 33(11), 4013–4027. https://doi.org/[retrieve from article page]
▸ Common error: Do not put the journal name in sentence case. The article title is sentence case. The journal name keeps title case and is italicized.
▸ Format:
Last, F. M. (Year). Title of paper. Name of Conference Proceedings, Volume, Article number or page range. https://doi.org/xxxxx
▸ Example (Wang source):
Wang, W. (2024). [Full paper title]. SHS Web of Conferences, 199, [article number]. https://doi.org/[retrieve from source]
▸ Note: SHS Web of Conferences entries use article numbers, not traditional page ranges. Retrieve the full DOI from the original publication page.
▸ Format:
Organization Name. (Year, Month Day). Title of page. Website Name. URL
▸ For no date (n.d.):
Johns Hopkins Medicine. (n.d.). Social media and mental health in children and teens. https://www.hopkinsmedicine.org/health/wellness-and-prevention/social-media-and-mental-health-in-children-and-teens
▸ Do not add a retrieval date unless the content is explicitly designed to change over time. For most stable health pages, retrieval date is not required in APA 7th.
▸ Format (for the Surgeon General advisory cited in your thesis):
U.S. Department of Health and Human Services. (2023). Social media and youth mental health: The U.S. Surgeon General’s advisory. https://www.hhs.gov/surgeongeneral/priorities/youth-mental-health/social-media/index.html
▸ Note: This is already cited in your thesis. Include it as Source 7 (secondary) if your instructor accepts government advisory reports.
APA 7th Edition Formatting Rules That Catch People Out
- Hanging indent: Every reference entry uses a hanging indent — first line flush left, subsequent lines indented 0.5 inches
- Alphabetical order: Reference list is alphabetized by first author’s last name — the annotations follow the same order
- DOIs as hyperlinks: DOIs should be formatted as live hyperlinks (https://doi.org/…) per APA 7th — not just the number
- Author names: List all authors up to 20; after that use first 19 names, ellipsis, then final author’s name
- Journal volume vs. issue: Volume number is italicized; issue number in parentheses is not — 33(11) is correct, not 33(11)
- No “Retrieved from” before URLs in APA 7th unless content may change over time

Search Strategy: How to Find 3 More Credible Sources Quickly
You need 2 more primary sources and 1 more secondary source. Here is a practical approach that does not waste time on Google.
Start with PubMed and PsycINFO — Not Google
PubMed (pubmed.ncbi.nlm.nih.gov) is free, government-run, and indexes peer-reviewed clinical and public health research. PsycINFO indexes psychological research and is available through most university library databases. These are where the peer-reviewed primary sources live.
Google Scholar is a reasonable backup — it casts a wider net — but the results are noisier and you will have to evaluate credibility more carefully. Start with PubMed or PsycINFO. Use your library’s database portal if you have access.
Use These Specific Search Terms
For primary sources (original studies with data):
- “social media use” AND “depression” AND “adolescents” — filter: last 5 years, peer-reviewed
- “TikTok” OR “Instagram” AND “mental health” AND “children” — gets platform-specific research
- “screen time” AND “anxiety” AND “youth” AND “survey” — the word “survey” filters toward primary data studies
- “social comparison” AND “social media” AND “self-esteem” AND “teens” — connects to your thesis themes
For your secondary source:
- Search directly on cdc.gov, aap.org (American Academy of Pediatrics), or hhs.gov for reports and advisories
- The 2023 Surgeon General Advisory is already in your thesis — use it as Source 7
Use the Reference Lists of Sources You Already Have
This is the fastest method. Open the Shoshani et al. (2024) article. Go to its reference list. Every source it cites is a credible peer-reviewed source on the same topic. Pick two that look relevant, find the original articles, and evaluate whether they present original data (primary) or synthesize others’ work (secondary). This method is called “citation chaining” and it consistently surfaces high-quality sources in a fraction of the time that keyword searching takes.
Filter Ruthlessly by Date and Study Type
Your thesis is about the current generation of children. A study from 2015 was conducted before TikTok existed. Filter search results to 2020–2026 for primary research. The landscape of social media and the research on its effects have changed significantly since COVID. Recency matters here more than it does in most topics.
Also check that what you are reading actually collected new data. If the first paragraph of the paper says “we reviewed 40 studies” or “this meta-analysis examined” — that is a secondary source. If it says “we recruited 500 adolescents” or “participants completed a survey” — that is primary. The method section makes it obvious.
Three High-Probability Search Targets for Your Topic
- American Academy of Pediatrics (AAP) research — the AAP publishes extensively on screen time guidelines and social media effects on children; their journal Pediatrics is peer-reviewed and directly relevant to your thesis population (children under 16)
- JAMA Pediatrics and JAMA Network Open — these medical journals regularly publish large-scale original studies on social media and youth mental health with strong methodology
- U.S. Surgeon General’s Advisory (2023) — already referenced in your thesis; freely available at hhs.gov; serves as your remaining secondary source and is directly citable in APA format as a government report
How to Answer the Three Reflection Questions
These questions are not asked at the end because they are an afterthought. They are a separate piece of analytical writing that sits alongside the bibliography. Each one needs a substantive, evidence-supported paragraph — not a sentence or two.
Question 1: What Search Strategy Advice Would You Give a Student Just Starting Their Search?
This question is asking you to teach someone else how to do what you just did. The stronger answers are specific — not “use credible sources” but “use PubMed and filter by publication date and study type.” Think about what you wish you had known before starting. What databases worked? What search terms were productive? How did you figure out whether something was primary or secondary? What made you trust or distrust a source?
Your answer should cover: which databases to start with and why, how to construct a search term (Boolean operators — AND, OR, NOT), how to filter by date and peer-review status, and what signals make a source credible (journal reputation, sample size, methodology transparency, author credentials). Cite your APA Style manual or your university’s library guide if applicable.
Specific Elements to Include in Your Search Strategy Answer
- Name specific databases (PubMed, PsycINFO, ERIC, Google Scholar) and explain when to use each
- Explain Boolean search construction: “social media” AND “mental health” AND “adolescents”
- Advise filtering by date (last 5 years for a current topic like this), peer-review status, and study type
- Mention citation chaining — using an already-found source’s reference list to find more
- Explain the difference between a primary research article and a secondary review at the level of reading the abstract and method section
- Note that for policy/government sources, going directly to hhs.gov, cdc.gov, or aap.org yields higher-quality results than general search engines
Question 2: What Themes or Patterns Emerged Across Your Sources?
Look across all 7 sources and find what they have in common. You are not summarizing each source again here — you are identifying what multiple sources say about the same underlying issue. This requires you to actually have read all 7 sources before writing this section.
Based on what your four provided sources cover, some themes you will likely find include: the dose-response relationship (more social media use = worse mental health outcomes, but not always linearly); the role of social comparison and FOMO as psychological mechanisms; the protective role of offline social support; differences between passive use (scrolling) and active use (creating, communicating); the gap between parental perception and actual adolescent experience; and the complication introduced by positive effects alongside the negative ones (Wang 2024 explicitly finds both).
How to Write the Themes Answer Without Just Re-Summarizing Each Source
Write thematically, not source-by-source. Instead of “Wang found X, Shoshani found Y,” write “Across multiple sources, the relationship between social media use and negative mental health outcomes appears to be moderated by the presence of offline social support (Shoshani et al., 2024; [other source]). This pattern suggests that the harm is not inherent to the technology but to what it displaces.” That is a theme with evidence behind it — not a list of summaries.
Question 3: What Gaps, Contradictions, or New Questions Emerged?
This is the highest-order question and the one that separates strong answers from adequate ones. You are not being asked whether your sources are complete. You are being asked to think critically about what the existing research does not know yet.
Gaps in this literature include: most studies focus on adolescents aged 13+, leaving younger children (8–12) underresearched despite being an increasingly active social media demographic; much of the research is conducted in Western, high-income countries, which limits generalizability; the technology itself keeps changing faster than research cycles — studies from 2020 may not reflect TikTok’s current algorithmic design; and longitudinal research is expensive and rare, so most studies are cross-sectional snapshots that cannot establish causation.
Contradictions worth noting: the Wang (2024) study finds both positive and negative effects of short-form videos, which sits in tension with the predominantly harm-focused framing of studies like Shoshani et al. (2024). This contradiction is not a flaw in the literature — it is a genuinely unresolved empirical debate. Your answer gets stronger when you name that tension specifically.
Common Mistakes in Annotated Bibliographies — and the Fix for Each
| ❌ The Mistake | Why It Costs You | ✓ The Fix |
|---|---|---|
| Copying the article abstract as the annotation | It is plagiarism. Turnitin will catch it. It also misses the evaluation and relevance components entirely. | Read the abstract, close it, and write the summary in your own words from memory. Then add your evaluation and thesis connection. |
| Writing annotations that only summarize — no evaluation | Summary alone is the lowest-scoring annotation. It shows you read the source, not that you thought about it. | For every source, add one sentence on methodology quality (sample size, study design, peer-review status) and one sentence connecting it explicitly to your thesis. |
| Misclassifying primary vs. secondary sources | If you submit with 3 primary and 4 secondary when the assignment requires 4 and 3, you have not met the requirement. | Check the method section of every source. “We recruited participants” = primary. “We reviewed existing studies” = secondary. It is always in the first two paragraphs. |
| Using the APA 6th edition format instead of 7th | Several rules changed between editions — including how DOIs are formatted, the publisher location rule, and running heads. | Use apastyle.apa.org as your reference — it is maintained by the APA and reflects the current 7th edition standards. Do not rely on old handouts. |
| Treating the discussion questions as a brief afterthought | These three questions are a separate analytical task that requires engagement with all 7 sources together. One or two sentences each is not enough. | Write at least two substantial paragraphs per question, using in-text citations to show that your reflections are grounded in what you actually read. |
| Finding sources that are too general — not specific to the thesis population | A source about “adults and social media” does not directly support a thesis about children under 16. The research populations must match. | Every source should involve participants aged 16 or under, or focus explicitly on adolescent or childhood development. Filter your searches by population, not just topic. |
| Alphabetizing by first name instead of last name | APA requires alphabetical order by first author’s last name. “Wang” comes after “Shoshani.” Mixing this up is an automatic formatting deduction. | Sort entries by last name before finalizing. Many word processors have a sort function — use it on a plain text version of your list to check. |
| Skipping hanging indents | Hanging indent is a core APA formatting requirement. Missing it signals you did not apply the style guide. | In Word: select your reference text, go to Paragraph settings, and set “Special: Hanging” to 0.5 inches. Do not manually add spaces. |
