The current study is an evaluation of the Turning Points parenting curriculum specially designed for use with incarcerated populations. The project combines intensive parent education with supervised offender mother/child visits in special family visiting rooms as well as ongoing offender support groups to help offender mothers become more effective parents. The current study will add to this body of literature by reporting results from three years of parenting classes; data was collected for a substantial number of participants (n = 204 unduplicated). In addition, longitudinal data is available for a select group of women (n = 18) who participated in the program over multiple years. Incarcerated women who meet program criteria self-select to participate. A pretest is administered to every participant at the beginning of each of the 10 parenting lessons and a posttest, exactly like the pretest, is administered to every participant at the end of every parenting lesson to assess any knowledge gained. Paired samples t-tests revealed that mean posttests scores were consistently significantly higher than pretest scores for all lessons and all years. Results also show an increase in parenting confidence during the class. Longitudinally, paired samples t-test results indicate four topic areas were not statistically significant between Time 1 and Time 3, indicating women retained some knowledge. Overall the evidence shows parent education programs can make a real difference in stopping the intergenerational cycle of incarceration by stopping the intergenerational cycle of ineffective parenting.
