Abstract

Accurate diagnosis of attention-deficit/hyperactivity disorder (ADHD) is crucial and challenging in clinical practice. To date, research has focused on assessment tools specific to ADHD. The primary aim of the current study is to investigate the usefulness of the Self-Report Symptom Inventory (SRSI), a new, universal self-report instrument designed to detect disordered symptom reports, making this the first study to employ this instrument in the context of ADHD. The secondary aim is to investigate the relationship between symptom validity tests (SVTs) and a performance validity test (PVT), the Reliable Digit Span (RDS). A simulation design was employed, with a control group (CG; N = 60), a feigning group (FG; N = 60), and an ADHD patient group (AG; N = 25), sampled through convenience. The SRSI performed comparably to a commonly administered ADHD assessment tool, the Conners’ Adult ADHD Rating Scale (CAARS). Using its official cut-off score, the SRSI Pseudo scale in particular yielded a sensitivity of 72.1% and specificity of 64.0%. It distinguished between FG and AG with a large effect size (d = 1.21) compared to the CII (d = 0.44; Fuermaier et al., 2016) and ACI (d = 0.55; Becke et al., 2021). The RDS was moderately negatively correlated to the SVTs, meaning underperformance is associated with elevated symptom reporting. It detected a different subgroup of simulators than the SVTs, meaning they tap into a different aspects of response bias. The current study supports the use of the SRSI as a general assessment tool in detecting noncredible ADHD. Keywords: attention-deficit hyperactivity disorder, adult ADHD, simulation study, noncredible presentation, feigning, assessment, CAARS, SRSI, RDS
