Attitudinal data on industrial workers in six countries supported the hypothesis that locus of control is significantly related to job involvement, i.e., that internals are more involved in their jobs than externals. The relationship was much stronger for males than for females in five of the six countries. However, virtually identical correlations were found for skilled and unskilled workers in most countries. Further analyses tended to rule out cultural values, worker age, and work experience as being responsible for the observed locus of control-job involvement relationships.
