A high school population ( N = 541) was administered the Rotter Locus of Control Scale in April and again the following November. At the second testing the MacDonald-Tseng and Rotter InternalExternal Locus of Control Scales were given to examine their concurrent validity.Test-retest reliability of the Rotter Scale was determined. Concurrent validity between the Rotter and MacDonald-Tseng scale (as the criterion measure) was established.EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT 1976, 36, 473-475. THE social learning theory developed by Julian B. Rotter examines the generalized expectancies with which subjects view reinforcement. When a subject perceives a reinforcement as &dquo;contingent upon his behavior or personal characteristics&dquo; he is said to be viewing with an internal locus of control. When a subject perceives a reinforcement as not being entirely contingent upon his actions, the residual becomes luck, chance, or powerful others. The subject is said to have an external locus of control (Rotter, 1966).The objectives of this study were ( 1 ) to investigate the test-retest reliability of the Rotter Internal-External Locus of Control Scale (a 29-item, forced choice six filler format) over an eight-month time period and (2) to examine the concurrent validity of the Rotter Internal-External Locus of Control Scale with a criterion measure repre-

The interrelationships among locus of control, attitudes toward the poor, attitudes toward the supervisor, job satisfaction, and the performance ratings of practicing rehabilitation counselors were studied. Ninety counselors were surveyed with a battery of attitude questionnaires. Results indicate that counselors with an internal orientation have more positive attitudes toward the poor than counselors with an external orientation. It was further observed that internally oriented counselors received higher performance ratings than externally oriented counselors. Finally, it was found that internal orientation was associated with higher job morale, greater job satisfaction, and more positive attitudes toward supervisors. Implications of the findings are discussed in the context of client-counselor relationships and of the consequence that these data may have in counselor preservice and inservice training.The present study investigates variables that are of potential significance in vocational rehabilitation. These variables are attitudes toward the poor and internalexternal locus of control, as defined by Rotter (1966).Recent literature (MacDonald, 1971) has called attention to the relevance of Rotter's internal-external locus of control construct to the rehabilitation process. According to Rotter, those who have an external-control orientation ("externals", as opposed to "internals") believe that their lives are controlled by fate, chance, luck, or powerful others. Consequently, externals do not try to better their circumstances, despite the fact that they may be motivated to do so.Various research studies have shown that externals are less open to remedial programs than are internals.
