Childhood Obesity Discussion: six-article appraisal guide
A 250-word discussion post summarising six childhood obesity articles and giving one strength and one weakness for each, judged against whether the article supplies sufficient evidence for your own proposed practice change. In-text citations required, scholarly sources, website sources preferred.

What does "sufficient evidence for your practice change" actually ask?
This looks like a summarising exercise and is really an appraisal exercise, and the distance between those two readings is most of the grade. Six articles inside about 250 words leaves roughly forty words each, so there is no room for background on childhood obesity and no room to recite what every author concluded. What the prompt actually asks for is one strength and one weakness per article, and it fixes the standard those judgements answer to: whether the article "may or may not provide sufficient evidence for your practice change." That clause is the assignment. A strength is not that the study is recent or the journal is well regarded. It is a feature of the design, the sample or the setting that makes the finding transferable to the change you intend to make on your own unit, with your own patients. Everything else is padding the word count cannot afford.
The second thing the wording does is make every judgement relative rather than absolute. An article is not strong or weak on its own; it is strong or weak for your change. A well-powered randomised trial of a school-based physical activity programme is excellent evidence and still weak support for a clinic-based parental counselling protocol, because the setting and the delivery agent both differ. A small qualitative study of parents' beliefs about portion size may be thin as evidence of effect and genuinely strong support for how you would frame the counselling script. Assessors reward students who name the practice change first and then let it do the appraising, and they mark down posts where the same two sentences about sample size and publication date are recycled six times over. The habit to build is to finish each entry by asking what your decision would still be missing if this were the only article you had read.
The format constraint deserves planning rather than compression at the end. Forty words per article realistically buys you one sentence of summary carrying design, population and the headline finding, one sentence naming the strength, and one naming the weakness. Write the six entries in that fixed shape and the post reads as a considered appraisal rather than a list. Because in-text citations are required and website sources are preferred, prefer the guideline and surveillance sources you can cite by organisation and year, and keep the citation inside the summary sentence so it does not eat into your word count twice. Choose the six articles so they differ in design, not just in topic, or you will find yourself writing the same weakness repeatedly. A trial, a cohort study, a systematic review and a qualitative study will each fail your change in a different way, and that variety is exactly what the marker is looking for.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Appraise a research article against a stated practice change rather than in the abstract.
- 02Distinguish an evidentiary strength from a presentational or recency judgement.
- 03Compress a summary to design, population and finding in a single sentence.
- 04Select a set of articles that differ in design so the appraisals do not repeat.
- 05Use in-text citation inside a hard word limit without losing content.
Read the full question
Review every instruction before using the planning guidance that follows.
Turn the brief into deliverables
- 01A discussion post of about 250 words; no title page required.
- 02A summary of six articles on childhood obesity.
- 03One strength and one weakness for each of the six, framed as sufficiency of evidence for your practice change.
- 04In-text citations, with scholarly references; website sources are explicitly preferred.
A fixed three-sentence shape for each of the six articles
Name the practice change in one sentence
State the change you intend, its setting and its delivery agent, because everything after this is judged against it.
Article entries one to three
Three fixed-shape entries: design, population and finding; then the strength; then the weakness.
Article entries four to six
Three more entries, deliberately drawn from different designs so the appraisals do not converge.
One closing line on sufficiency
Say whether the six together are enough to support the change, and if not, what design is missing.
Trim to the word count
Cut background and hedging first; the six entries and the practice change are what is being marked.

Search sequence
- 1.Write the practice change down first; it is the query that decides which articles are worth reading.
- 2.Use the USPSTF recommendation to find the trials it graded — those are already appraised for you and make good contrasts.
- 3.Pick a CASP checklist matched to each design, and take the strength and weakness from the checklist items rather than inventing them.
- 4.Check that the six articles cover at least three different designs before you start writing.

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.

Review before submission
Common mistakes
- Appraising the articles in the abstract instead of against the specific practice change, which is what the prompt names.
- Offering recency or journal reputation as the strength, neither of which is a property of the evidence.
- Writing the same weakness ("small sample") for several articles because they were chosen for topic rather than design.
- Spending fifty words on background about childhood obesity prevalence and then running out of room by the fourth article.
- Summarising the authors' conclusions rather than their design, population and finding.
- Never stating what the practice change is, which leaves every sufficiency judgement unanchored.
Submission checklist
- The intended practice change is named early enough to anchor all six appraisals.
- Each of the six entries carries a summary, a strength and a weakness.
- Every strength refers to design, sample or setting, not to recency or prestige.
- Every weakness explains what your decision still lacks, not just a generic limitation.
- The six articles differ in design, so the appraisals do not repeat.
- In-text citations are present and the post is close to 250 words.
- No title page has been added, since the brief says one is not required.
