The Cross-Cultural Ability of the Inventory of Problems-29-M (IOP-29-M) to Detect Feigned Symptom Presentations: A Replication of Akca et al. (2023) on a Romanian-Speaking Sample

Year: 2025

Type: article

Abstract: This study replicated research on the ability of the Inventory of Problems-29 (IOP-29) to detect honest, feigning, and random responding, and investigated the accuracy of its memory module (IOP-M) in a Romanian-speaking sample. 127 participants, randomized into three groups, were assessed online with the IOP-29-M, in each responding condition. The standard cutoff of ≥.50 on the IOP-29 False Disorders Probability Scale accurately discriminated honest from feigned protocols. The Random Responding Scale showed promise in indicating careless responding. Combining the IOP-29 FDS and IOP-M improved classification accuracies. Results support the IOP-29-M’s cross-cultural validity and its utility in forensic and clinical settings.
