Class drift and schizophrenia.

Area of Science:

• Psychiatry
• Developmental Psychology
• Sociology

Background:

• Longitudinal study initiated in 1962 by Mednick & Schulsinger.
• Analysis of 207 children of mothers with schizophrenia (high-risk) and 104 low-risk controls.
• Focus on understanding schizophrenia's impact beyond diagnosis.

Purpose of the Study:

• To investigate class mobility patterns in individuals who develop schizophrenia.
• To test the class drift hypothesis using a prospective research design.
• To compare socio-economic trajectories of high-risk schizophrenics versus controls.

Main Methods:

• Matched comparison of 14 high-risk schizophrenics, 14 high-risk non-schizophrenics, and 14 low-risk non-schizophrenics.
• Matching criteria included age, sex, and social class of origin.
• Assessment of highest class attainment and socio-economic status in 1972.

Main Results:

• High-risk non-schizophrenics showed similar class attainment to low-risk controls.
• High-risk schizophrenics demonstrated significant downward social mobility.
• Comparison revealed a distinct downward trajectory for schizophrenic subjects.

Conclusions:

• The findings support the class drift hypothesis in schizophrenia.
• Schizophrenia is associated with a decline in socio-economic status over time.
• Early life risk factors may influence long-term social and economic outcomes.
