Brief Summary

Establishment of effective, efficient, and evidence-based interventions in rehabilitation of working memory (WM) deficits after acquired brain injury (ABI) is sorely needed. Despite robust evidence for the usefulness of clinical hypnosis in a wide range of clinical conditions, and improved understanding of mechanisms underlying it ́s effects, the potential of clinical hypnosis in cognitive rehabilitation is virtually unexplored. The current study seeks to replicate resent intriguing findings where large effects of hypnotic suggestion were seen on WM capacity following ABI, and further, explore underlying mechanisms of change.

Outcome Measures

Primary Outcomes (2)

  • Change in WM on neuropsychological tests

    Measured by the WM Index WAIS IV

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

  • Change in WM-related symptoms in everyday life

    Assessed with the WM subscale from the Behavior Rating Inventory of Executive functioning Adult version (BRIEF-A) on a 3-point scale: Never a problem, sometimes a problem or often a problem. Higher scaled score indicates higher level of problems with WM.

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

Secondary Outcomes (5)

  • Change in cognitive composite score as seen on neuropsychological tests

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

  • Change in TBI related challenges in everyday life

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

  • Change in self reported mental health

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

  • Change in quality of life

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

  • Changes in community integration

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

Other Outcomes (2)

  • Changes in ABI related self-efficacy

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

  • Changes in WM self-efficacy

    Change from Baseline (T1) to immediately after the intervention period (T2) and 8 months after Baseline (T3)

Study Arms (3)

Hypnotic suggestion

EXPERIMENTAL

During the first phase of the study, two groups will receive identical hypnotic inductions followed by targeted suggestion for one group and non-targeted suggestion for the other. The targeted procedure consists of suggestions about enhancing WM functions through the instantiation of preinjury WM ability in the present using age regression and visualizations of brain plasticity.

Other: Hypnotic suggestion

Mindfulness

ACTIVE COMPARATOR

The targeted procedure consists of suggestions about enhancing WM functions through the instantiation of preinjury WM ability in the present using age regression and visualizations of brain plasticity.

Other: Mindfulness

No treatment

NO INTERVENTION

The passive control group receives no intervention

Interventions

The intervention group will receive four weekly 60 min. sessions with hypnosis treatment including induction followed by hypnotic suggestion.

Hypnotic suggestion

The active control group will receive four weekly 60 min. sessions of induction and mindfulness-based instructions.
