Contradictory evidence exists on the Multidimensional Health Locus of Control scale's factor structure and the psychometric equivalence between Form A and Form B. University students ( = 359) completed the Multidimensional Health Locus of Control and General Self-Efficacy scales. The three-factor model had better fit and parsimony in both Forms. 'Internal' scale negatively correlated with 'chance' but positively with 'others'. The two external scales positively correlated. The scales' reliability was satisfactory, but the two Forms were not psychometrically equivalent. Convergent validity was confirmed. The evidence suggests a three-factor structure and psychometric non-equivalence of the two Forms. Researchers should make an informed choice on which Form to use.
关于多维健康控制点量表的因子结构以及A版和B版之间的心理测量等价性，存在相互矛盾的证据。大学生（n = 359）完成了多维健康控制点量表和一般自我效能量表。三因素模型在两个版本中都具有更好的拟合度和简约性。“内控”量表与“机遇”呈负相关，但与“他人”呈正相关。两个外控量表呈正相关。量表的信度令人满意，但两个版本在心理测量上并不等价。收敛效度得到了证实。证据表明存在三因素结构以及两个版本在心理测量上的不等价性。研究人员应在使用哪个版本上做出明智的选择。
