目前，这项基于记录的研究调查了智商在预测丹麦50年来出生的年轻男性在教育和职业成就方面的广泛指标中的作用。研究人群包括自1950年以来出生并在1968年至1984年和1987年至2015年期间出现在征兵委员会面前的所有男性（N = 1,098,742）。智商是在18岁时由Borge Priens Prove评估的。不成功的教育成就表现为没有获得证书就离开初中，25岁时没有完成青年教育，30岁时没有完成导致职业资格的教育，以及30岁时中断教育的总次数。不成功的职业成就表现为：30岁时没有就业、没有接受教育或培训，30岁时失业，30岁时领取疾病津贴，30岁时领取福利，30岁时领取残疾养恤金，30岁时领取总收入。采用二值logistic回归、负二项回归和中位数回归来估计智商与不成功教育和职业成就的关系。结果表明，低智商是所有不成功的教育和职业成就指标的强有力和一致的预测因子。总之，研究结果表明，智力评估可能为教育计划提供关键信息，并为功能不佳的学童和青少年提供有关当前教育目标和更遥远的工作相关未来的咨询。
The present register-based study investigated the role of IQ in predicting a wide range of indicators of unsuccessful educational and occupational achievement among young men born across five decades in Denmark. The study population comprised all men who have been born since 1950 and have appeared before a draft board during the periods from 1968 to 1984 and from 1987 to 2015 (N = 1,098,742). IQ was assessed by Borge Priens Prove at age 18. Unsuccessful educational achievement was indicated by leaving lower secondary school without a certificate, by no completed youth education at age 25, by no completed education leading to vocational qualifications at age 30, and by the total number of interruptions to education at age 30. Unsuccessful occupational achievement was indicated by not being in employment, education or training at age 30, by unemployment at age 30, by receiving sickness benefits at age 30, by receiving welfare benefits at age 30, by receiving disability pension at age 30, and by gross income at age 30. Binary logistic regression, negative binomial regression and median regression were used to estimate the associations of IQ with unsuccessful educational and occupational achievement. The results showed that low IQ was a strong and consistent predictor of all indicators of unsuccessful educational and occupational achievement. In conclusion, the study findings suggest that assessment of intelligence may provide crucial information for educational planning and counselling of poor-functioning schoolchildren and adolescents with regard to both the immediate educational goals and the more distant work-related future.
