Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main cognitive complaint in brain-injured patients is often the everyday disorganization caused by Executive Function (EF) deficits. EF deficits are often seen in patients with psychiatric disorders i.e. depression or anxiety. In order to minimize everyday disorganization, effective EF interventions are required. Interventions using compensatory strategies have the potential to enable patients to minimize disabilities, minimize participation problems and to function more independently in daily life. A well-known evidence-based intervention that uses compensatory strategies is Goal Management Training (GMT), a training that has been found to alleviate depressive symptoms in a depressed population. GMT entails learning and applying an algorithm, in which a daily task is subdivided into multiple steps to handle executive difficulties of planning, and problem solving. To adopt the GMT strategy and ensure maximal profitability for patients, they have to learn to use the algorithm in different situations and tasks. Therefore, GMT is comprehensive, time-consuming and thus labour-intensive. Along with this, brain games become increasingly attractive as an (add-on) intervention, most notably in an effort to develop home-based personalized care. Until now, however, the rationale behind brain games is based on what can be considered the restorative approach (i.e. strengthening of executive problems) rather than practicing compensatory strategies, with little or no transfer to improvements in daily life functioning. This study therefore aims to assess the potential of a newly developed Brain Game, based on compensatory strategies, as an add-on to GMT to develop a shortened and partly self-paced GMT intervention. The primary objective of this study is to assess whether the use of a compensatory brain game supported GMT treatment could be of interest in people with EF deficits after ABI that also suffer from depression or anxiety, to improve goal achievement, their executive function performance during goal-related tasks, and their executive performance during an ecological valid shopping task. Also we assess whether psychological symptoms alleviate following the GMT intervention and at 6-weeks follow-up. The study will be a multiple-baseline across individuals single-case experimental design (SCED). The study population consists of brain-injured patients, between 18 and 75 years old that receive in-patient mental neuropsychiatric healthcare. Participants eligible for the study must have EF deficits due to (nonprogressive) Acquired Brain Injury (ABI), minumum time post-onset of 3 months and depressive or anxiety symptoms. EF deficits will be assessed by extensive neuropsychological examination. Participants will be recruited from an inpatient clinic. In the course of one and a half year four participants will be recruited.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

A randomized Single-case Experimental Design (SCED) with a follow-up period of 6 weeks. Participants will be first assigned to a baseline phase (phase A). The start of the treatment phase (phase B) is determined randomly for each participant, given the restriction that the baseline phase (phase A) should last for at least three weeks (21 days) and at most five weeks (30 days). This means that the treatment phase can start on any day between the 21th and the 30th days. So, in the first three weeks, all participants are in the baseline condition. The duration of baseline will thus be different for each subject. Nonspecific effects, such as linear trends, retesting or non-specific recovery, can be controlled by this approach, since expected changes in level of performance due to treatment should parallel this stepwise onset of therapy procedure.

Phase A acts as a control and is therefore compared with phase B.

Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors

The target behavior (i.e. performance on an untrained shopping task) will be measured repeatedly, on a minimum of six occasions in each phase where possible, in accordance with the recommendations of the What Works Clearinghouse and RoBiNT criteria. Repeated measures of target behavior will be assessed via the OxMET-NL task and is scored automatically: no assessor input is required to either save or score the main outcome data. The secondary outcome measure(s) are scored by an outcome assessor who is blind to the order in which the secondary outcome measure(s) were taken.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No Intervention: Baseline phase (Phase A)

o At the start of the study, all participants are assigned to the baseline phase (phase A). During phase A, patients do not receive interventions related to executive function problems. The start of the intervention phase (phase B) is determined randomly for each participant, given the restriction that phase A should last for at least three weeks (21 days) and at most five weeks (30 days). This means that phase B can start on any day between the 21th and the 30th days, resulting in a total of 10 possible assignments. So, in the first three weeks, all participants are in phase A. The duration of phase A will thus be different for each subject. Phase A acts as a control and is therefore compared with phase B.

No interventions assigned to this group

Experimental: Intervention phase (Phase B): Goal Management Training

During the intervention phase (phase B), all included participants will have 6 sessions of Goal Management Training (GMT; twice per week) in which two individual chosen IADL-tasks will be subdivided into multiple steps under guidance of a therapist using the GMT method. In addition participants play the compensatory brain game in which they are challenged to apply the learned GMT strategy in an imaginary and safe environment.

Group Type EXPERIMENTAL

Compensatory brain game supporting Goal Management Training intervention

Intervention Type BEHAVIORAL

o The investigational treatment is only given during the intervention phase (phase B), and consists of six treatment sessions. In the treatment sessions, patients learn and apply the GMT algorithm. This means that the multiple steps of the GMT as well as the actual performance of the IADL-task goals will be learned under guidance of a therapist. In order to facilitate generalization, patients will learn to use the algorithm during the performance of untrained tasks by playing the treatment supporting Plan Game. Because of this, patients are able to practice the application of the GMT algorithm independently outside the therapy session. Besides, the intervention also includes a Plan Tool. This is a mobile application that can be used as an aid during the performance of (instrumental) activities of daily living (IADL) tasks in order to perform activities more independently. The GMT treatment sessions are given twice a week (max. 60 minutes for each attendance).

Follow-up period

A follow-up period of six weeks takes place after phase B. During this follow-up period, patients receive no intervention.
