Eighty-nine subjects of the original sample of the National Institute of Mental Health joint study by the United States and Israel, known as the Israeli High-Risk Study, were given a clinical interview and a questionnaire measuring locus of control (LOC) during the second phase of the study, when the subjects were adolescents. During phases 3 and 4, approximately 8 and 15 years later, the subjects were psychiatrically assessed and 56 of them repeated the LOC questionnaire. The two measures of LOC were correlated, as were general assessments of mental health (MH). Adolescent LOC was related to lifetime MH, although LOC and MH were not related to each other concurrently in either adolescence or adulthood. The best predictive model for lifetime MH outcomes was a combination of adolescent MH and LOC variables; background variables, including parental schizophrenia, were superfluous. The data suggest that whereas adolescent MH is the best predictor of general MH, adolescent LOC is the better predictor of schizophrenia and major affective disorders.
美国国立精神卫生研究所与以色列联合开展的一项研究，即以色列高危研究，其原始样本中的89名受试者在研究的第二阶段接受了临床访谈以及一份测量心理控制源（LOC）的问卷，当时这些受试者处于青少年时期。在第三阶段和第四阶段，大约分别在8年和15年后，对这些受试者进行了精神病学评估，其中56人再次填写了LOC问卷。LOC的两种测量方法之间存在相关性，心理健康（MH）的总体评估之间也存在相关性。青少年时期的LOC与一生的MH相关，尽管在青少年期或成年期，LOC和MH在同一时期并不相互关联。预测一生MH结果的最佳模型是青少年MH和LOC变量的组合；包括父母患精神分裂症在内的背景变量是多余的。数据表明，虽然青少年MH是总体MH的最佳预测指标，但青少年LOC是精神分裂症和重度情感障碍的更好预测指标。
