Forensic vigilance in forensic professionals: development, reliability and factor structure of the forensic vigilance estimate

Abstract

PurposeForensic vigilance is a central competency that forensic professionals need to meet the complex demands of working in forensic settings. Until recently, no instrument for forensic vigilance was available. This study aims to develop a self-assessment tool of forensic vigilance for individuals and teams working in forensic settings, and investigated its psychometric properties.Design/methodology/approachThe Forensic Vigilance Estimate (FVE) was presented to 367 forensic psychiatric professionals and 94 non-forensic psychiatric professionals by means of an online survey. Professionals rated themselves on 15 aspects of forensic vigilance.FindingsThe results indicated that the FVE had good psychometric properties, reflected by a good to excellent internal consistency (Cronbach’s α of 0.903), a good split-half reliability (0.884) and good test–retest reliability (0.809). The factor structure of the FVE was captured by a one-factor model (RMSEA 0.09, SRMR 0.05, TLI 0.91 and CFI 0.92). Proportion of explained variance was 52%. Forensic professionals scored significantly higher than non-forensic professionals on the FVE (t(459) = 3.848, p = 0.002).Practical implicationsThese results suggest that the FVE may reliably be used for research purposes, e.g. to study the effects of targeted training or intervention or increasing work experience on forensic vigilance or to study which factors influence forensic vigilance.Originality/valueThis study represents the first attempt to capture forensic vigilance with a measuring instrument.
