The Efficacy of Goal Focused, Non-Pharmacological Treatment for Persons With ADHD/ADD.

The Efficacy of Goal Focused, Non-Pharmacological Treatment for Persons With ADHD/ADD. A Randomized Controlled Trial.

The study aims to improve the understanding of non-pharmacological treatments of ADHD with a particular emphasis on coping with executive problems. Executive functions can be defined as those abilities necessary to formulate goals, carry them out effectively and enabling a person to engage successfully in independent, purposive, self-serving behavior.

The intervention consists of:

1. Eight psycho-educative group sessions focusing on Goal Management Training (GMT), a method aiming to enhance goal directed behavior, developed by Levine and colleagues in 2011.
2. Four individual sessions where the participants are guided through the process of formulation individual goals for improving functioning in everyday life. The method used for goal setting is Goal Attainment Scaling (GAS), developed by Kiresuk and Sherman in 1968.
3. Bi-weekly telephone follow up the first three months preceding the group sessions, focusing on the attainment of GAS-goals.

Adult participants with ADHD/ADD are recruited from the outpatient psychiatric health care clinic, DPS Nedre Romerike at Akershus University Hospital and are randomized into either 1) an intervention-group, receiving the intervention described above or 2) a control-group receiving treatment as usual.

It is hypothesized that the intervention will improve executive functioning, reported ADHD-symptoms and psychological well-being. It is also hypothesized that the participants sucessfully will formulate and implement GAS-goals and that goal attainment will sustain throughout the follow-up phase.

Given the 1) high prevalence and possible detrimental consequences of ADHD, 2) limitations related to pharmacological ADHD-treatments, 3) scarce evidence of the effects of long term use of pharmacological treatment and 4) limitations related to the present evidence base for the effects of non-pharmacological treatments, research on the effects of non-pharmacological ADHD treatment is highly required.

Goal Management Training (GMT) (Levine et al, 2011) is a theory-driven intervention relying on metacognitive strategies to reengage endogenous attention processes, in addition to teaching problem-solving techniques to improve goal-directed capacity. GMT draws upon theories regarding sustained attention, mindfulness and goal processing. The aim is to increase awareness of errors and strategies while facing complex, everyday challenges. The patient learns to stop ongoing behavior, define goal hierarchies and to adjust and monitor goals. Generalization to everyday-life is heavily emphasized.

In previous studies, GMT has been shown to improve goal directed behaviour including generalization effects to daily life and psychological well-being in various neurological conditions, e.g. acquired brain injury and spina bifida (Hypher et al, 2019; Stubberud et al, 2014; Tornås et al, 2016) and normal ageing (Levine et al, 2007). The evidence of GMT in the adult ADHD populations is scarce.

To the investigators knowledge, this is the first trial combining group based, GMT and individual goal setting within the frame of a psycho-educative, cognitive rehabilitation intervention in order to help adults with ADHD cope with executive problems in everyday life.

Research questions and hypotheses

1. Does the intervention combining GMT, psychoeducation and implementation of GAS goals result in improvements in executive problems for adults with ADHD when compared to treatment as usual (TAU)? Hypothesis 1: Post intervention changes in executive functions will be reflected in improved scores on a measure pertaining to daily life executive function (BRIEF-A) at five- and eights months follow up.
2. Does the intervention result in improvements of reported ADHD symptoms when compared to TAU? Hypothesis 2: Post intervention changes in ADHD-symptoms will be reflected in improved scores on a measure pertaining to ADHD-symptoms (ASRS-v1.1) at five and eight months follow-up.
3. Does participation in the intervention improve psychological well-being when compared to TAU? Hypothesis 3: Post intervention changes in psychological well-being will be reflected in improved scores on a measure pertaining to psychological well-being (HSCL-25) at five and eight months follow-up.
4. Will the participants succeed in attaining individual GAS goals for coping with executive problems? Hypothesis 4: The participants will successfully formulate and implement GAS-goals for coping with executive problems in everyday life. Goal attainment will sustain throughout the three-month long implementation phase and sustain until the eight month follow up.

Inclusion Criteria:

1. Diagnosis of Hyperkinetic disorder, ADHD or ADD. Both patients recently diagnosed at DPS and patients previously diagnosed can be included.
2. Subjective complaints about executive problems affecting everyday life, operationalized as a score of 60 or above on BRIEF-A or as reported in the inclusion interview.
3. Motivation for working with the executive problems in order to increase coping in everyday life.
4. Adequate language skills to participate in group discussions without any need for an interpreter.

Exclusion Criteria:

1. CNS injury or disease other than hyperkinetic disorder, ADHD or ADD.
2. Ongoing substance-abuse.
3. Psychopathology that would negatively interfere with participation in the intervention, e.g. ongoing psychosis, present suicidal risk to severe to be treated in an out-patient setting or personality disorders considered to severe to be treated in a group-based out-patient setting.
