Measuring everyday adaptation after imprisonment: The post-release living inventory for ex-prisoners (PORLI-ex).

Background: The number of ex-prisoners worldwide has constantly been increasing in recent years. Currently, little is known about post-release daily adaptation, not to mention valid and reliable instruments for post-release daily routines pertinent to mental health.

Objective: This study aims to develop and validate a self-report instrument, hereafter referred to as Post Release Living Inventory for Ex-prisoners (PORLI-ex).

Methods: Three separate samples of ex-prisoners were recruited to complete an online survey (N=1,277, age range=17-89 years, 53.2% male, 72% white).

Results: The final model evidenced acceptable goodness-of-fit and consisted of 45 items on nine dimensions, which loaded on three second-order factors: Consolidation (three dimensions; e.g., Institutional Routines), Replacement (two dimensions; e.g., Maladaptive Behaviors), and Addition (four dimensions; e.g., Socializing with Ex-prisoner Friends) (α=.695-.915). Convergent validity was demonstrated in the positive correlations with IADL, SOLI, MLQ, GSE-6, and MSPSS. Discriminant validity was demonstrated in the weak correlations with the LEC-5 and perceived social and personal cost of punishment. Criterion-related validity was demonstrated in the correlations with psychiatric symptoms and crime-related outcomes and incremental validity in the correlations with these measures independent of the scores on IADL, SOLI, MLQ, GSE-6, and MSPSS.

Conclusion: This study calls for more resources on fostering psychological strengths and resilience through regularizing basic daily life experiences on top of traditional interventions for risk management among the ex-prisoners.
