Adult adjustment problems of separated children: a longitudinal study from birth to the age of 23 years

The study investigated the risk of adult criminality, alcohol abuse and mental health problems (between 18 and 23 years of age) that were associated with a) the number of separations to which a child had been subjected, b) age at separation and c) the sex of the child. Data were used from a Swedish longitudinal study of a large representative sample. It was found that: 1) experiencing a separation during childhood was associated with a significantly increased risk of later maladjustment for all 3 adjustment problems; 2) the risk increased approximately additively with the number of separation events experienced during childhood; and 3) for all 3 adjustment problems, the risks were largest in the case of early (before age 7) and late (age 12-16) separations and there was not any significant risk increase arising from separations in the intervening age period. These risk increase patterns were similar for males and females, but the levels differed, since male sex in itself almost quadrupled the odds for later criminality and alcohol abuse.
