Rotter's Internal-External (I-E) locus of control scale, the MMPI, and the CPI were administered to a sample of 100 males heterogeneous in age and education level. Relationships between I-E and the other measures were examined and a substantial number of significant correlations were found. Considerable variance in I-E scores could be accounted for by similar variance in MMPI and CPI responses, but a discriminant analysis failed to enable reliable predictions of I-E from other scales. The findings qualify the interpretation of correlational relationships found in previous research concerning I-E and suggest specific directions for future investigations.
对100名年龄和教育水平各异的男性样本施测了罗特内外控量表、明尼苏达多相人格测验（MMPI）和加州心理调查表（CPI）。研究了内外控与其他测量之间的关系，发现了大量显著的相关性。MMPI和CPI反应中的相似差异可以解释内外控分数中相当大的差异，但判别分析未能从其他量表可靠地预测内外控。这些发现限定了以往关于内外控的研究所发现的相关关系的解释，并为未来的调查提出了具体方向。
