Fatigue in an adult attention deficit hyperactivity disorder population: A trans-diagnostic approach.

Objectives: Trans-diagnostic approaches suggest that key cognitive and behavioural processes maintain symptoms across a wide range of mental health disorders. Fatigue is a common clinical feature of attention deficit hyperactivity disorder (ADHD) in adulthood; however, empirical data supporting its prevalence are lacking. This study aimed to collate outcomes from outpatient services to (1) investigate the prevalence of fatigue in adults with ADHD, (2) examine symptoms of ADHD in adults with chronic fatigue syndrome (CFS), and (3) consider secondary clinical characteristics common to both disorder groups.

Protocol for a proof of concept randomized controlled trial of cognitive-behavioural therapy for adult ADHD as a supplement to treatment as usual, compared with treatment as usual alone.

Background: ADHD is prevalent in adults and frequently associated with impairment and distress. While medication is often the first line of treatment a high proportion of people with the condition are not fully treated by medication alone, cannot tolerate medication or do not wish to take it. Preliminary studies suggest that psychosocial approaches are a promising adjunctive or alternative treatment option.

Negative perfectionism increases the risk of fatigue following a period of stress.

Cognitive-behavioural models of excessive fatigue suggest that people who believe that failure to meet high standards indicates unacceptability to others (a form of 'negative perfectionism') are at risk of fatigue after a period of illness or stress. The present study investigates this using a prospective design and possible mediating factors between such beliefs and fatigue were also investigated. Undergraduate students completed questionnaires at the beginning of the academic year (time 1; n = 436) and again following a time of academic pressure, 16 weeks later (time 2; n = 206).
