Disorder-Specific Symptoms and Psychosocial Well-Being in Relation to No-Show Rates in Forensic ADHD Patients

No-show rates in forensic psychiatry are related to higher recidivism risk and financial costs in mental health care, yet little is known about risk factors for high no-show rates. In this study, the extent to which disorder specific symptoms and psychosocial well-being are related to no-show rates in forensic patients with ADHD was examined. Sixty male patients with ADHD (M age = 35.9, SD = 8.6) who received treatment in a Dutch forensic outpatient center completed the Adult Self-Report on disorder-specific symptoms and general psychosocial well-being. Data on no-show rates and background characteristics were obtained via electronic patient files. Independent sample t-tests showed a trend in which patients with high no-show rates (15-45% missed appointments) had more ADHD symptoms compared to patients with low no-show rates (0-14.9% missed appointments). Furthermore, multivariate regression analyses showed that rule-breaking, externalizing problems and somatic problems were associated with higher no-show rates, whereas anxiety problems were associated with lower no-show rates. Results suggest that no-show rates in forensic patients with ADHD are related to specific psychopathological symptoms. This knowledge can be used to prevent no-show in forensic psychiatric treatment.
