This data collection examines the effects of determinant sentencing on prison climate and administration. Three data collection periods are covered in the dataset. Parts 1-3 contain data taken from a total random sample of offenders housed at five prisons over all three data collection periods. Part 4 is an additional sample from the state of Connecticut of inmates serving determinate sentences, collected during the third period of data collection. Parts 5 and 6 comprise indeterminate sample data from all three data collection periods, while Parts 7-9 contain determinate panel sample data from all three collection periods. There were six questionnaires used in collecting these data, covering inmates' feelings about their arrest, court case, and conviction, their feelings about the law, physical problems developed during their prison term, how their time was spent in prison, family contacts outside prison, relationships with other prisoners and guards, involvement in prison programs, and criminal history.
