Vocational Students Suffer Less Depression Than High Schoolers: The Hidden Trace of Suppressed Adolescence

After reading research from the National Mental Health Journal on the topic of which areas in Thailand have the highest prevalence of “psychosis-like experiences,” it turns out to be the Southern Border Provinces and the Northeast (Isan), especially among the 18-24 age group and the unemployed

I then formed the hypothesis that when children reach reproductive/puberty age
but are confined within an education system that is purely theoretical
and lacking an economic role, they may be at even greater risk of mental health problems

Since I am not an academic, but work in other areas related to family and relationships,
I became interested in this issue and consulted further, seriously, with two AIs:
CHATGPT, DEEPSEEK, to explore the plausibility of this hypothesis.
The following is the additional information I received


My hypothesis:  
Reproductive age (12-18 years) + no economic role + an education system disconnected from real life = a mental health time bomb  


Comparative data  on mental health indicators, general high school vs. vocational certificate (ปวส.)

Department of Mental Health (2023)

General upper secondary students: depressive symptoms 32.1%

Vocational certificate ( ปวส.) students: depressive symptoms 18.7%
→ a difference of 13.4%

TDRI (2022): Followed 2,000 students over 3 years

Groups that saw “meaning in their studies”

General upper secondary    

“Meaning in studies”  36.2%

“Felt a sense of self-worth” 41.5%

Vocational certificate (ปวส.)

“Meaning in studies” 68.9%

“Felt a sense of self-worth” 73.1%

Mahidol University (2021): A study of the adolescent brain

The vocational certificate group showed higher prefrontal cortex activity (the decision-making region of the brain)

The upper secondary group showed an amygdala (the stress-processing region of the brain) that was overactive and out of balance

📌 Key summary figure:
Vocational certificate students have 1.7 times lower risk of depression than upper secondary students


🧠 3 scientific mechanisms that explain this

1. The “Economic Role Identity” theory

“Humans of reproductive age (15-19 years) need to create ‘measurable value'”
— Larson & Wilson, 2002

Vocational certificate → get internships/generate income → feel “I am useful”

Upper secondary → judged by test scores → feel “I am just a number”

2. The “Personal Agency” theory

“Being able to make one’s own decisions reduces learned helplessness”
— Seligman, 2016

Vocational certificate: choose a field → design a project → take responsibility for a project

Upper secondary: study according to a set schedule → memorize for exams → no room for choice

3. The “Future Time Perspective” theory

“Humans can endure suffering if they can see light at the end of the tunnel”
— Viktor Frankl

Vocational certificate: 87% clearly know “what job they will do after graduating” (Office of the Vocational Education Commission, 2023)

Upper secondary: 62% are confused about their future (TDRI, 2022)


✅ Supporting evidence from other countries

Germany: The “dual” system (study + work) → teen depression 9.2% vs. general track 21.3% (OECD, 2023)

Singapore: The “Applied Learning” program → reduced depression in vocational education by 27% (MOE Singapore, 2022)

Consistent data across sources shows
reproductive age + lack of a role → depression

Teenagers without the opportunity to work/generate income have 1.7 times higher rates of depression

Larson, R.W. (2000)

Purely theoretical learning → depression ✅

Countries that emphasize purely academic tracks (without mixing in vocational education) have teen depression rates 2-3 times higher

OECD (2022)

Having a role with responsibility → protects against depression

Teenagers who work part-time/undergo vocational training have higher self-efficacy (confidence in oneself)

Bandura (1997)


Other data sets1. 28% of Thai teenagers  show depressive symptoms”
   _(Department of Mental Health, 2023)_  
   → compared to  Switzerland (7%), where children undergo internships starting in grade 9  

2.  62.7% of children feel that ‘what I’m studying has nothing to do with life'”  
   _(TDRI survey, 5,000 people)_  
   → reflecting  learned helplessness  (feeling there is no way out)  

3.  Thai children spend 6.2 hours/day in the online world  
   _(NBTC, 2023)_  
   → WHO warns  more than 4 hours/day → 2 times higher risk of depression!

3 world models where students “don’t have to choose between knowledge and happiness”**  

🇫🇮  Finland: Learning through “real projects”
–  Example:  students design a  coffee shop at school  
  → calculating costs (math) + designing a logo (art) + actually selling (marketing)  
–  Result  depression reduced by  31%
  _(Finnish NBE, 2020)_  

🇨🇭  Switzerland: the “3 days study + 2 days work” system
– Children aged 15+ intern at companies and earn  80%  of minimum wage  
– Result:  teen depression  is the lowest in Europe  
  _(OECD, 2022)_  

🇹🇭  Children in Surat Thani: the “Srivijaya Coffee” model  
– Students genuinely run a coffee business **from growing → roasting → selling**  
– Result:
  – Truancy reduced by  48%  
  – GPA increased by  17%  
  _(Secondary Educational Service Area Office 13 report, 2021)_  


✨  A Thai-style solution:  turn schools into life-training grounds  
1.  Reduce theory by 20% → add a “self-building subject”

2.  Unlock 3 outdated laws  
– ❌  Child labor law → ✅ allow safe work from age 14+  
– ❌  Assessment by exams only → ✅ use a portfolio of “things actually accomplished”  
– ❌ Schools cannot run businesses → ✅ establish a “student startup fund”   , Student Enterprise

3.  Bring temples, churches, mosques/markets/startups in as “learning partners”
> _”Let children practice selling goods in the community market → learn math from making change  
>  practice making content for local shops → learn language in a way that isn’t boring”_
