Cognitive state, substance use patterns and outcome after discharge from Kfar Izun, a unique rehabilitation facility

Abstract

We studied cognitive performance following discharge from a novel rehabilitation facility, treating individuals with psychosis that developed during trips abroad following mandatory military service. Montreal Cognitive Assessment (MoCA), phonetic and semantic fluency, State-Trait Anxiety, and self-Efficiency were administered before discharge, and 3 and 6 months after discharge. Of the 43 participants (30.2% females), 23(54.8%) had cognitive impairment (MoCA <27), and 15(35.7%) had poor phonetic fluency. Anxiety trait and state were high and inversely correlated with self-efficacy (R=-0.48, p = 0.001) and phonetic fluency (R=-0.43, p = 0.004) and was higher among those who experienced physical exposure, females, and those who served in non-combat army units. Six months after discharge, of 32 participants, 28 were working/studying with a 58.1% reduction in smoking and alcohol consumption, and 16 participants stopped substance use. Phonetic fluency improved among the high anxiety state group with no change among the others. High anxiety levels lowered among those who were still using drugs after six months. The anxiety level lowered and 87.1% of the participants were conducting a productive lifestyle at 6 months after discharge, but half still abused cannabis. Bigger sample and longer follow up would be needed to learn more about the impact of rehabilitation.
