Treatments started at different times across settings. Behavioural patterns and emotional states studied in context of family. Proband = family member with trait who is singled out: 1st degree relatives, 2nd degree relatives, distant relatives. 1st degree relatives raised in diff settings are of interest. Fraternal twins (dizygotic): different eggs and share 50% of genes. Genetic linkage analysis: studying inherited characteristics of disorders in families, genetic markers: exact location of genes that lead to disorder. Association studies: compare genetic markers in people with/without disorder. Provides insight to how problems are created and how they can become more serious. 4 prevention strategies: positive/health promotion, universal, selective. Cross section of a population across different age groups. Cohort = participants in each age group: cohort effects. Retrospective effect (looking back: gives inaccurate picture of how disorder may have developed over time. Look at one group over time: assess changes in members, don"t have cohort-effect problems.
