In one line: How you explain a disorder shapes how you treat it. A psychological treatment changes thinking and behaviour.
In the health and well-being context, treatment and prevention are key areas of study. Each explanation points to a matching treatment: biological to medication, cognitive to therapy, sociocultural to social support. We keep depression as the running example.
This links to responsibility (effective, ethical care is a duty) and to change (treatment aims to change behaviour and well-being).
How CBT works
Spot the thought
Notice the automatic thought behind a low moment: 'I always fail'.
Check the evidence
Ask what supports the thought and what goes against it.
Replace it
Write a fairer thought: 'I failed this test, not everything.'
Test it in life
Plan an activity and see what really happens: a behavioural experiment.

Remember: Explain it, then treat it. Each approach suggests a treatment; CBT targets the thoughts.

Key idea: Treatments match the explanation; prevention (health promotion) tackles problems before they start.
Approaches to treatment
Biological treatment
Medication (such as antidepressants) that alters neurotransmission. Fast for some, but side effects, and it does not address causes.
Psychological treatment
Therapy (such as CBT) that challenges and changes negative thinking. Needs effort and time.
Sociocultural treatment
Building social support, reducing isolation, tackling stigma so people seek help.
Prevention
Health promotion: education, screening, reducing risk factors, to stop problems before they start.
Medicate · Retrain thinking · Support · Prevent
Take treating depression. Medication may lift mood; CBT changes the self-blaming thoughts; social support reduces isolation; and prevention (stress education, early screening) lowers risk in the first place.
Go further: higher-level insight: Combined treatment usually works best. Because the causes interact, combining medication, therapy and support often beats any one alone.
March and colleagues (2004), the TADS trial, tested this with teenagers with depression in the United States.

Key idea: Each treatment has strengths and limits; effectiveness depends on the person and is judged with evidence.
Strengths
- Medication: can work quickly; widely available
- Therapy (CBT): tackles thinking; lasting skills
- Social support: reduces isolation; low harm
Limitations
- Medication: side effects; may not address causes; relapse
- Therapy: takes time and effort; access varies
- Social support: hard to measure; not a full treatment alone
So no single treatment is best for everyone. A strong evaluation compares treatments, notes that effectiveness varies between people, stresses that combining approaches often helps most, and judges effectiveness with evidence, while respecting the duty to do no harm.
Watch out: 'Effective' must be measured. Claiming a treatment works needs evidence, ideally controlled trials with follow-up, not testimonials.
