This study is based on two previous studies that showed a post-treatment decrease in total criminal thinking (PICTS) and an increase in total sense of coherence (SOC) among youths and adults. The current study investigated whether these interventions changed the sub-scales of PICTS and SOC, and whether an increase in SOC would mediate a decrease in PICTS. Among both groups, the mean value of the sub-factors of PICTS decreased by the interventions, and increased for SOC sub-factors meaningfulness and manageability. Only among the adults, the increase in total sense of coherence and the sub-factor of manageability mediated the decrease of criminal thinking.
