This study is a part of the research project Automated Phone Follow-Up in
Correctional Services. The overall aim of the research project was to investigate if Interactive Voice Response can be used as tool to investigate, monitor and influence levels of stress, depression, anxiety, and use as well as urge of alcohol and drugs among paroled offenders. IVR is a technology based on automated phone interviews, which means that a computer has been programed to call up, ask questions, record answers and provide a feedback to the paroled offenders. Previous publication from the research project explored if it is possible to use automated phone interviews (IVR) to follow-up the development of stress, psychological mood, and use of alcohol and drugs in paroled offenders during the first 30 days following probation (Andersson et al, 2011). The main aim of this study was to investigate if there were any differences in psychological mood, substance use and personality between paroled offenders that participated in at least one automated phone follow-up and paroled offenders that did not participate in any automated phone follow-up. Another aim of this study was to describe the psychological mood, substance use and personality in the total sample group of paroled offenders. The only significant difference between participants and non-participants in the phone follow-up´s was found for the personality trait guilt. The paroled offenders that participated in the phone follow-up scored significant higher on guilt, a scale measuring feelings of guilt and shame after wrongdoing, cheating, of having bad thoughts. The results of the descriptive analysis showed high levels of substance misuse, depression and anxiety symptoms in the total sample group of paroled offenders. The paroled offenders also scored high on personality scales socialization, impulsivity and monotony avoidance compared to healthy subjects.
