The Rosenbaum Self Control Schedule is a self-report instrument developed to assess individual tendencies to apply self-control methods to the solution of behavioral problems. Tested on Hebrews and English-speaking Americans, it was found to transfer easily from one situation to the other. When administered in a battery of self-report questionnaires to South African university students it was found that while means of the total sample were similar to those reported overseas, the means of black and white students within the sample were significantly different from each other, with black students having higher self-control scores than the white students in the study and higher than those reported in previous studies. The study was repeated in this research project using a larger group of black students. The finding of significantly higher self-control scores was replicated. This finding was not due to response set, either acquiescence or social desirability, although black subjects were found to be more subject to social desirability response set. Distributions of the samples showed a group of low scoring white subjects for which there was no equal in the black sample. The findings suggest that black university students in South Africa have high levels of learned resoursefulness. This may be due to a selection process reflecting the relative difficulty with which black students reach university level - difficulties relating to student unrest, educational and financial limitations and economic and social drawbacks so that only those students with moderate to exceptional levels of problem solving stategy skills do succeed. Such individuals should be good candidates for cognitive therapies. Item and factor analyses showed the SCS to be psychometrically adequate for the white group but were much less conclusive for the black sample. In this group, a lower Cronbach's alpha was obtained and the factor analysis was less clear.

Indiana University-Purdue University Indianapolis (IUPUI) / Minimal attention has been devoted to examining the dimensionality of self-control. The present study tested a multidimensional model of self-control in which dimensions were based on the nature of the behavior required (i.e., persistence, initiation, cessation, or prevention). A total of 336 undergraduates completed measures of self-control and psychological well-being. Seventy-four of these participants completed behavioral self-control tasks representing the proposed subtypes. Participants’ GPAs were obtained from the Registrar. Stop self-control was inversely related to previously-validated measures of persistence (β = -.61, p = .010) and prevention (β = -.56, p = .040) self-control and demonstrated differential predictive ability of persistence and prevention compared to the other proposed subtypes. Initiation self-control was inversely related to life satisfaction (β = -.35, p = .012) and demonstrated differential predictive ability of life satisfaction compared to stop self-control. These results were interpreted with caution due to inadequate power and questionable validity of several of the behavioral self-control tasks. Both handgrip persistence (r = -.25, p = .033) and blinking prevention (r = -.29, p = .023) were associated with depression. These pairwise correlations were not significantly different from each other, suggesting that no conceptual distinction should be made between persistence and prevention self-control. Confirmatory factor analyses of self-report data revealed that items clustered based on domain rather than on type of behavior required for self-control exertion. Thus, the structure of self-control remains unclear. Limitations of the present study and implications for future research are discussed.
