3.4 Developmental Level Across the Lifespan
Key Takeaways
Developmental level is a person's stage of physical, cognitive, emotional, and social development, which can differ from chronological age, especially with an intellectual or developmental disability.
Erikson's stages give a practical lens: adolescents work on identity, young adults on intimacy, middle-aged adults on generativity, and older adults on integrity versus despair, which shapes goals, coping, and teaching.
Parents or legal guardians generally consent for minors, but state law lets emancipated minors and, for certain services, minors themselves consent to care.
An adult with an intellectual or developmental disability is presumed to make their own decisions unless a court has appointed a guardian; supported decision-making and adapted teaching come first.
Start pediatric-to-adult transition planning early (often around ages 12 to 14) and teach young adults directly with teach-back at their developmental level.
Developmental Level Across the Lifespan
The ACM content outline names developmental level twice. Domain 1 asks case managers to assess the patient's developmental level and cognitive status (task 1B3), and Domain 2 asks them to integrate cultural competence and the patient's developmental level into the plan of care (task 2K). Most ACM-RN work involves adults, but hospital case managers also discharge adolescents, young adults leaving pediatric care, adults with intellectual and developmental disabilities, and very old adults. Developmental level shapes who makes decisions, how teaching is done, and which goals matter to the patient.
What "Developmental Level" Means
Developmental level is a person's stage of physical, cognitive, emotional, and social development. It usually tracks age but can differ from it. A 25-year-old with a moderate intellectual disability may read at an early-elementary level and need concrete, step-by-step teaching, while a 15-year-old with a long-standing chronic illness may manage a complex insulin regimen independently. Assess developmental level from the patient, family, school or day-program records, prior evaluations, and direct observation, alongside cognitive screening (Section 3.2).
A Lifespan Lens: Erikson's Psychosocial Stages
Erik Erikson's stages offer a practical way to anticipate what matters to a patient during illness:
| Life Stage | Developmental Task (Erikson) | Case Management Implications |
|---|---|---|
| Adolescence (about 12–18) | Identity vs. role confusion | Privacy and peer image matter; include the teen in decisions, talk with them alone, and expect adherence to dip when treatment sets them apart from peers. |
| Young adulthood (about 19–40) | Intimacy vs. isolation | Work, relationships, and parenting drive goals; illness that threatens a job or relationship calls for social work and benefits support. |
| Middle adulthood (about 40–65) | Generativity vs. stagnation | Many patients care for children and aging parents at once; the plan must fit caregiving and work obligations. |
| Late adulthood (65 and older) | Integrity vs. despair | Life review, legacy, independence, and end-of-life preferences come forward; advance care planning and goals-of-care conversations fit naturally. |
Piaget's cognitive stages also help with children and with some adults who have an intellectual disability. Concrete thinkers (typical of roughly ages 7 to 11, or adults functioning at that level) learn best from demonstration, pictures, and one step at a time; abstract reasoning usually emerges in adolescence.
Decision-Making and Consent by Developmental Stage
- Minors: Parents or legal guardians generally consent for patients under the age of majority (18 in most states). Seek the child's assent, meaning their agreement in age-appropriate terms.
- Emancipated minors: Minors emancipated by court order or by statute (in many states, through marriage or military service) may consent to their own care.
- Minor-consent statutes: State laws let minors consent to specific services, such as care for sexually transmitted infections, contraception, prenatal care, and some substance use or mental health treatment. State law also governs what parents may see in those records.
- Young adults: At 18 the patient becomes the decision maker even if parents still manage appointments and bills. Parents have no automatic legal authority unless the young adult names them as health care agent or a court appoints a guardian, so discuss a health care power of attorney or supported decision-making before the eighteenth birthday when it is needed.
- Adults with intellectual or developmental disabilities: Adults are presumed to make their own decisions unless a court has appointed a guardian. Use supported decision-making, plain language, visual aids, and extra time; assess capacity for the specific decision (Section 4.1); and if a guardian exists, check whether the guardianship is full or limited.
Pediatric-to-Adult Transitions
Adolescents and young adults with chronic conditions (such as type 1 diabetes, congenital heart disease, cystic fibrosis, or sickle cell disease) are at high risk of gaps in care when they leave pediatric services. National health care transition guidance, such as the Six Core Elements framework from Got Transition, recommends starting transition planning around ages 12 to 14, building self-management skills over time, and transferring to adult care, commonly between ages 18 and 21. During a hospitalization, the case manager can:
- Confirm whether an adult primary care clinician and adult specialists are identified, and arrange a warm handoff.
- Check insurance changes at transition ages; for example, dependent coverage on a parent's employer or marketplace plan generally ends at age 26, and Medicaid eligibility categories can change at 19 or 21.
- Teach the young adult directly, not only the parent, using teach-back, and confirm who will refill medicines and schedule appointments.
Late-Life Development and Frailty
Older adults are a developmentally distinct group, not simply older middle-aged adults. Maintaining independence and meaning often outweigh disease targets. Hearing and vision loss, slower processing, and frailty affect teaching and discharge options. Adapt teaching with large print, a quiet room, hearing amplification, and shorter sessions, and involve caregivers when the patient wishes.
Integrating Developmental Level into the Plan of Care
| Plan Element | How to Adapt It |
|---|---|
| Goals | Frame goals around what matters at that stage: returning to school, keeping a job, caring for grandchildren, or staying at home. |
| Teaching | Match the method to the level: demonstration and pictures for concrete learners, chunk-and-check teach-back for everyone. |
| Decision maker | Identify who legally decides (parent, emancipated minor, adult patient, agent, or guardian) and who else should be involved. |
| Resources | Use developmentally appropriate services: school nurses and individualized education program teams, developmental disability agencies and Medicaid waivers, or Area Agencies on Aging. |
| Follow-up | Plan for the next transition: a pediatric-to-adult handoff, a day program, or home health for a frail older adult. |
Tip
When a question involves a teen, a young adult who has just turned 18, or an adult with an intellectual disability, ask two things first: who has legal authority to decide, and how teaching must be adapted to the person's developmental level.
A 17-year-old with type 1 diabetes who is not emancipated is ready for discharge after diabetic ketoacidosis. Who consents to the discharge plan, and how should teaching be approached?
The teen consents alone because they manage their own insulin, so the parents do not need to take part in teaching
A parent or guardian consents, the teen's assent is sought, and teaching includes the teen directly with teach-back
The hospital ethics committee consents, because adolescents cannot legally take part in medical decisions
The case manager consents as care coordinator, and teaching is given only to the parent to avoid confusing the teen
A 24-year-old patient with a moderate intellectual disability is hospitalized with pneumonia. No guardian has been appointed. The patient's mother asks to sign all consent forms because the patient "doesn't understand." What is the most appropriate response?
Have the mother sign every form, because adults with an intellectual disability cannot legally consent to treatment
Ask the probate court for emergency guardianship before any further treatment is given to the patient
Presume the patient decides, support decisions with plain language and the mother's help, and assess capacity for each decision
Let the attending decide everything under the emergency doctrine because the patient has a developmental diagnosis
Which action best integrates developmental level into the discharge plan for a 19-year-old with congenital heart disease who has just aged out of pediatric cardiology?
Keep scheduling all follow-up with the pediatric cardiologist indefinitely so the patient keeps a familiar team
Give the discharge instructions only to the parents, because the patient still depends on them financially
Defer transition planning until the patient's next admission so that this hospital stay is not prolonged
Arrange an adult congenital cardiology handoff, confirm insurance status, and teach the patient directly
