General strain theory regards strain as having three distinct sources: (1) blockage of desired goals, (2) withdrawal or loss of valued objects, and (3) introduction of negative stimuli. Previous empirical tests of general strain theory support this theory, but their shortcomings preclude the drawing of definitive conclusions. This study used data from the first and second waves of the National Youth Survey, a longitudinal study of the correlates of delinquency and drug use. The survey used a probability sample and drew 2,360 eligible youths 11-17 years old. The analysis used information from the 1,525 youths who were interviewed in both 1977 and 1978. Results revealed that several dimensions of general strain are positively related to involvement in a wide range of delinquent acts. Strain has both a direct effect on delinquency and indirect effects by weakening the inhibitions of the social bond and increasing a youth's involvement with delinquent peers. Findings indicated that general strain theory makes an important contribution to juvenile delinquency theory and that further research should focus on fully developing its implications.
