Sixty male alcoholic inpatients were administered the Locus of Control scale (IE), the Activity Preference Questionnaire (APQ), the Manifest Anxiety scale (MAS), and the Tennessee Self Concept scale (TSCS). Ss defined as having an external locus of control appeared significantly more anxious than internal Ss on the MAS; however, no differences were found between groups on the APQ or TSCS scales. The self-report (MAS) and nonobtrusive (APQ) measures of anxiety were not correlated significantly. A differential pattern of correlations was found between the MAS and APQ and TCSC subscale scores. The obtained correlations support the contention that the MAS may measure more accurately a dimension of neuroticism and/or negative self-concept rather than anxiety. Further research appears necessary to investigate the internal consistency and dimensionality of the MAS.
