Fifteen-Year-Old With Sleep Loss, Job, and New Friends

Diego is 15 years 5 months. He has always been an A/B student. Since starting a 20-hour-per-week restaurant job three months ago, he sleeps from 1:00 a.m. to 6:00 a.m. on school nights and 10:00 a.m. to 2:00 p.m. on weekends. His grades have fallen to C's. He has a new group of friends who vape; he says he has tried vaping twice but not alcohol or cannabis. He has dropped his former soccer team because 'it was my parents' dream.' He argues with his mother about curfew and says no one understands him. He eats breakfast rarely, drinks two energy drinks daily, and has lost 2 kg. He still enjoys making music, has one close friend, and denies sadness or hopelessness. His parents want to forbid the job and the new friends.

1. Which features of Diego's situation are normative adolescent development, and which require further risk screening? Explain your reasoning.

Read the worked answer

Normative features include increased autonomy, identity exploration, renegotiating parental goals, and a shift toward peers. Dropping soccer because it was a parent's dream can be a healthy differentiation move, and arguing about curfew is common. His sleep pattern also partly reflects the adolescent phase delay: melatonin secretion shifts later, making 1:00 a.m. sleep onset biologically easier and 6:00 a.m. waking difficult.

Risk features require screening: 5 hours of sleep on school nights, a 20-hour job, falling grades, twice-weekly energy drinks, 2 kg weight loss, and vaping. These could reflect sleep restriction, substance use, depression, or an eating/body-image issue, but his continued music involvement, one close friend, and denial of sadness are protective. Use a sleep diary, PHQ-9 or similar mood screen, substance-use screen, and school report. The reasoning is that normative exploration does not make sleep loss or weight loss harmless; the two must be separated before deciding on restrictions.

2. Evaluate the parents' plan to forbid the job and the new friends. What parenting approach is more likely to support development and safety?

Read the worked answer

Forbidding both abruptly is likely to escalate conflict and reduce parental monitoring, because Diego is in a period when autonomy and peer belonging are central. An authoritative approach is more defensible: high warmth and high, explained limits. Parents can negotiate a cap on work hours, a school-night curfew, no vaping in the home or car, and family check-ins, while allowing Diego input into which limits are reasonable. They should state the rationale in terms of sleep, safety, and grades rather than control.

Connect limits to the specific data: 5 hours of sleep, 20 hours of work, and grade decline. Keep the close friend and music as protective supports. If screening reveals depression or escalating substance use, seek clinical care rather than relying on restriction alone. The developmental reasoning is that autonomy support plus monitoring predicts better adjustment than either permissiveness or harsh control.
