On 15 October 2026, the University of Cambridge published a report on a systematic review of young people's attitudes to health-data research. According to the university's announcement, researchers from the Department of Psychiatry carried out a systematic review of existing evidence among children and young people, drawing on both qualitative and quantitative studies. The review covered 17 studies involving 6,261 participants, including at least 4,710 children and young people and 1,443 parents and carers. Cambridge describes it as a synthesis of existing studies, not a new experiment.
The headline finding was not simple approval. Cambridge reported that support for health-data research was conditional: participants wanted research to be carried out ethically, by trustworthy organisations, and with appropriate safeguards and transparency around how their data are used. Respondents were concerned about the potential loss of privacy and the possibility of being identified even when data are described as anonymised, and about misuse of data by organisations, particularly commercial companies. The report also highlights a practical transparency question: understanding why data are being used, who may access them, and what safeguards are in place. A further finding was that young people wanted a greater say in decisions about their data as they grow older. The researchers emphasise that these findings should not be interpreted as one uniform view among all underrepresented groups.
The report concerns health-data research. The exercise below applies its emphasis on transparency to preparation for a classroom survey, such as a proposed question about club timings or study spaces. These are our editorial suggestions, not a Cambridge survey method or an intervention tested by the review. Even an apparently simple survey needs teacher review before anyone collects answers. For this preparation exercise, use invented responses and avoid health questions or identifiable information about classmates.
The practical core of this exercise is a one-page, plain-language data-use note, written before any survey link is sent. Here is what it should cover, based on our editorial preparation for a hypothetical classroom survey.
First, the question and purpose. State in one or two sentences what the survey asks and why. For example: this survey asks classmates which after-school club times work best, so the student council can propose two alternative slots to the activities coordinator. If you cannot state a concrete purpose, that is a sign the survey is not ready.
Second, only necessary non-sensitive fields. List every field you propose to collect and remove anything the purpose does not require. For a scheduling question, consider whether a preferred time slot alone would suffice. Names, phone numbers and health details have no place in this exercise. Even a year group combined with other answers might identify someone in a small class. Review combinations of fields and free-text prompts with your teacher, rather than judging privacy by whether a question sounds harmless.
Third, who can access responses and where they are stored. Name the people who will see raw answers — for instance, two student-council members and the supervising teacher — and name the storage location, such as a school-approved form tool or a shared document folder. Vague phrases like "only we will see it" are less useful than naming roles and places.
Fourth, what will be reported. Explain the output format: a summary of counts and general themes, with no individual answers quoted or attributed. Say who will receive the summary — the class, the coordinator, a notice board — so respondents know the reach of the results.
Fifth, retention and deletion plans. Agree a realistic retention period with your supervisor, then state when the response file will be deleted and who will do it. Check the approved tool’s settings and policies before promising anything. Copies, downloads and backups may follow different retention rules. Describe only the actions you can carry out; if platform retention is unclear, resolve it with the supervisor before collection. An unexplained limitation is a reason to revise the plan, not a reason to promise guaranteed deletion.
Sixth, realistic limits on withdrawal. Separate choosing not to participate from removing an answer already submitted. Ask your teacher what withdrawal process fits the proposed survey. If an approved process lets the team locate a response, explain how someone can request removal and any actual deadline. If answers are collected without a way to locate an individual response, removal after submission may be impossible from the outset. Say so before participation. Do not promise to exclude someone’s answer later if you cannot identify which answer is theirs.
That distinction also matters for anonymity. The Cambridge report describes concerns about identification even when data are called anonymised. For this exercise, do not equate “no name field” with “anonymous.” A form may record email addresses or other metadata, and a distinctive combination of answers may reveal a person. A free-text description can identify a classmate without naming them. Inspect the tool’s actual settings with your teacher, avoid unnecessary identifying detail, and make only specific, verified statements about collection and access. Removing a name column alone does not establish anonymity. When uncertain, describe the limitation and revise the survey instead of promising complete protection.
Two process steps complete the preparation. First, rehearse with invented responses before collecting anything real. Create several fictional answers without drawing on classmates’ experiences, run them through the proposed form, and produce the summary you would share. Look for unnecessary detail or outputs that could expose an individual. This is a check of the proposed workflow, not proof that it is safe. Second, ask a teacher or supervisor to review the note, questions, tool settings and reporting plan. Include a question for the reviewer: what should happen if someone enters identifying information in a free-text box? Resolve that before launch rather than improvising after collection.
This exercise does not replace school procedures, research approval or applicable law. It sets no universal consent age and does not certify compliance or demonstrate improved survey outcomes. Ask your supervisor which permissions and safeguards apply. If the proposed subject involves health or other sensitive information, stop this classroom exercise and seek appropriate guidance rather than extending this checklist to it.
Cambridge also reported that young people wanted more involvement in decisions about their data as they grow older. For the proposed classroom activity, invite questions about the explanation and make clear that declining the survey is an option. The goal of this preparation is an understandable plan that can be reviewed and corrected before data exist.
Next action: before you send any survey link, draft a one-page explanation covering purpose, fields collected, who can access responses, what will be reported, deletion plans and withdrawal limits. Test the full flow with invented responses, resolve every unanswered question, and ask your teacher to review the draft before you collect a single answer.

剑桥大学于2026年10月15日发布一项系统综述报告,梳理了关于青少年对健康数据研究看法的既有研究(17项研究、6261名参与者)。报告显示,支持是有条件的:青少年希望研究合乎伦理、由可信机构进行,并有保障措施和透明度;即使数据被称为匿名,他们仍担心被识别。本文将该证据作为启发,用于一项低风险课堂问卷的编辑准备练习:在发出问卷前,先起草一页简明说明,写清调查目的、仅收集必要的非敏感字段、谁可查看答案及存放位置、将如何汇报结果、保留与删除计划,以及撤回的现实限制。要区分真正匿名与仅删除姓名,不要承诺绝对匿名或保证删除;用虚构回答演练流程,并请老师审阅后再收集任何数据。
