Since 1966, locus of control as measured by the I-E scale has been shown predictive of many different dependent variables in both health and nonhealth situations. In hundreds of articles, expectancies have been reported to mediate perceptual, cognitive, and motivational processes. However, in many other investigations, locus of control has failed to predict the dependent variable being studied. Therefore, it is clear there are limitations to the predictive power of the construct. In recent years published research highlighting these limitations has resulted in a decrease in research about locus of control and the use of the I-E scale. Yet many investigators do not know or perhaps choose to ignore the criticisms published in recent years. Nurses who are interested in locus of control are encouraged to understand the construct and the frequent misapplications of it which occur, to realize the limitations of the I-E scale when considering instrumentation, and to consider multidimensional attribution theory as more appropriate to understanding behavior than locus of control.
自1966年以来，通过内外控量表测量的控制点已被证明能够预测健康和非健康情境中的许多不同因变量。在数百篇文章中，预期被报告为能够调节感知、认知和动机过程。然而，在许多其他研究中，控制点未能预测所研究的因变量。因此，很明显该构念的预测能力存在局限性。近年来，强调这些局限性的已发表研究导致关于控制点和内外控量表使用的研究减少。然而，许多研究者并不知道或者可能选择忽略近年来发表的批评意见。鼓励对控制点感兴趣的护士了解该构念及其经常出现的错误应用，在考虑测量工具时认识到内外控量表的局限性，并认为多维归因理论比控制点更适合于理解行为。
