‘No-show’ is important in today's mental healthcare services, yet in forensic psychiatry, little is known about its relationship to general and disorder-specific patient characteristics.

The aim of this article is to determine the prevalence of no-show and any general and disorder-specific features associated with no-show in a cohort of offenders with attention deficit hyperactivity disorder registered at a specialist forensic mental health clinic.

Participants were 118 adult men with a mean age just over 32 years (SD 8.75) attending forensic mental health outpatient clinics in the Netherlands who had a primary diagnosis of attention deficit hyperactivity disorder and who had been aggressive and/or delinquent.

Over a 1-year period, most patients (101, 86%) missed at least one appointment. The average number of appointments offered was 37.88 (SD = 27.27), and the average number of no-shows was 6.53 (SD = 5.99) per patient. Multivariate linear regressions showed a 10-fold likelihood of later no-shows if the first appointment was missed; not showing up after the intake procedure was also associated with higher rates of later no-show. None of the disorder-specific characteristics contributed to the problem.

No-show is of particular concern in forensic mental health settings. In the current study, no-show was primarily associated with features related to the time of initial consultation. More attention should thus be paid at this stage to using a standard method of assessing a wider range of variables likely to affect attendance.
