The growing interest in and use of goal-specific locus of control scales to investigate the significance of internal-external control beliefs in a variety of important life areas has prompted the development and preliminary validation of the Miller Marital Locus of Control scale (MMLOC). The 44-item scale measures the extent to which respondents view reinforcements in the marital domain as being contingent upon their own efforts and abilities, or as being due to factors outside their control. Results indicate that the scale has good internal consistency reliability. Intcrnalily lor marriage, as measured by the scale, is positively associated with intimacy within marriage and marital satisfaction. The scale is significantly correlated with life satisfaction now and in the future, but not with life satisfaction five years ago, providing some evidence of discriminant validity. Additional validity is found in the relationships with the affiliation but not the achievement scales of the Multidimensional Multiattributional Causality Scale (MMCS). Results al this initial stage of scale development arc therefore promising and suggest that the scale will be useful in investigating the role of expectancies for reinforcement in marriage.
