Situation: The nurse at the clinic of a public high school talks with students who come in for consultation.

A 15-year-old boy says he smokes a few cigarettes each week with his friends. Each of the following could help him quit. Which approach BEST fits his present cognitive stage?

## 보기

1. Have a respected older student tell how he quit smoking
2. Give him a written list of the harms of smoking to read at home
3. Let him set his own quit date and plan his own steps
4. Ask him to reason out how smoking may affect his future goals **✔ 정답**

**정답: 4**

## 해설

At 15 he is in Piaget's formal operational stage and can reason abstractly and hypothetically about the future, so asking him to work out how smoking now affects the goals he has set uses his thinking most fully. The other options are also useful, but each rests on a different idea: a peer model draws on social learning, letting him plan his own steps respects his growing independence, and a list of facts only gives information to take in.

Cognitive Stage and Cessation Approach

A 15-year-old is developmentally positioned in Piaget’s formal operational stage, which typically emerges around age 11 to 12 and continues through adolescence. In this stage, thinking shifts from concrete, tangible reasoning to abstract, hypothetical, and future-oriented reasoning. The adolescent can manipulate ideas mentally, consider multiple possibilities, and evaluate long-term consequences without needing to see or touch an object. This is precisely why asking the student to reason out how smoking may affect his future goals is the best fit: it directly engages the highest-level cognitive capacity available at this age.

The formal operational thinker can project current behavior into a hypothetical future and weigh how present choices either support or undermine personally meaningful outcomes. A 15-year-old who is beginning to set academic, athletic, or social goals can use abstract reasoning to connect smoking with reduced stamina, financial cost, or conflict with long-term aspirations. This approach does not simply deliver information; it requires the adolescent to construct the argument himself, which is the hallmark of formal operational thought.

The other options are not incorrect, but they rely on different developmental or learning mechanisms. A peer model telling how he quit draws on social learning theory—observing and imitating a respected figure—rather than on the adolescent’s own abstract reasoning. Letting the student set his own quit date and plan his steps respects autonomy and emerging independence, which is an important psychosocial need in adolescence, but it does not specifically require hypothetical or future-oriented thinking. Giving a written list of harms is a passive information delivery strategy; the student can read and memorize facts without engaging in the mental manipulation of ideas that defines formal operations.

Watch out! Do not confuse “independence” with “abstract reasoning.” An adolescent may want to make his own plan (autonomy) but still think concretely about the steps. The question asks which approach *best fits his cognitive stage*, not which approach respects his psychosocial needs.

Key point! In the formal operational stage, the most developmentally aligned intervention is one that asks the adolescent to generate the reasoning himself—weighing evidence, anticipating consequences, and linking present actions to future goals—rather than receiving a model, a list, or a ready-made plan.

Adolescent smoking cessation research consistently notes that youth-focused interventions often produce modest results, and that attitudes toward quitting are shaped by smoking history and developmental context [2][3]. While behavioral strategies and peer influences are commonly used, the cognitive capacity to think hypothetically about one’s own future is a distinct developmental asset that can be leveraged in counseling. A 15-year-old who is asked to reason through the impact of smoking on his goals is being invited to use the very cognitive tool that has newly matured—abstract, hypothetical, future-oriented thought [1]. This aligns the intervention with the student’s developmental stage rather than working around it.References (research sources)

Adolescent Smoking Cessation: Cognitive Stage ApproachTailoring interventions to Piaget's formal operational stage
A 15-year-old is in Piaget's formal operational stage, which enables abstract reasoning and hypothetical thinking about the future. The most effective approach is to ask the student to reason out how smoking may affect his future goals, engaging his highest cognitive capacity.

Other strategies remain useful but rely on different mechanisms: a peer model draws on social learning theory, letting him plan his own steps respects growing independence, and a written list only provides information to absorb.

CautionDo not rely solely on information-giving or external modeling for adolescents. The intervention should require the adolescent to construct the argument himself, connecting current behavior to personally meaningful long-term outcomes.
