Abstract

Introduction: Subjectively experienced cognitive decline in older adults is an indicator of increased risk for dementia and is also associated with increased levels of anxiety symptoms. As anxiety is itself emerging as a risk factor for cognitive decline and dementia, the primary question of the present study is whether an 8‐week mindfulness‐based intervention can significantly reduce anxiety symptoms in patients with subjective cognitive decline (SCD). The secondary questions pertain to whether such changes extend to other domains of psychological, social, and biological functioning (including cognition, self‐regulation, lifestyle, well‐being and quality of life, sleep, and selected blood‐based biomarkers) associated with mental health, older age, and risk for dementia. Methods: SCD‐Well is a multicenter, observer‐blinded, randomized, controlled, superiority trial, which is part of the Horizon 2020 European Union‐funded “Medit‐Ageing” project. SCD‐Well compares an 8‐week mindfulness‐ and compassion‐based intervention specifically adapted for older adults with SCD with a validated 8‐week health education program. Participants were recruited from memory clinics in four European sites (Cologne, Germany; London, United Kingdom; Barcelona, Spain; and Lyon, France) and randomized with a 1:1 allocation, stratified by site. Results: The primary outcome, change in anxiety symptoms, and secondary outcomes reflecting psychological, cognitive, social, and biological functioning are assessed at baseline, postintervention, and 4 months after the end of the intervention. Discussion: The study will provide evidence on whether a mindfulness‐based intervention can effect changes in anxiety and other risk factors for cognitive decline and dementia in older adults with SCD and will inform the establishment of intervention strategies targeted at improving mental health in older adults.

  • Two research groups investigated the effects of psychoeducation with MBSR-based therapy on individuals with SCD (n = 147, n = 38).

    “Two research groups investigated the effects of psychoeducation with MBSR-based therapy on individuals with SCD (n = 147 [68, 69], n = 38 [55, 56]).”

    From Psychotherapeutic interventions in individuals at risk for Alzheimer’s dementia: a systematic review (2022) · cites this paper as [68]

    The Introduction and Methods/design describe an MBSR-derived intervention with psychoeducational components for people with SCD. But this paper is a trial protocol: its Statistical considerations specify 64 participants per arm, not an investigated sample of 147. The n = 38 group is attached to other citations and is not assessed here. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • With regard to psychotherapeutic interventions, no data in individuals with SCD were identified, while data regarding psychoeducational approaches addressing individuals with SCD are available from four research groups.

    “With regard to psychotherapeutic interventions, no data in individuals with SCD were identified, while data regarding psychoeducational approaches addressing individuals with SCD are available from four research groups [55, 56, 61, 66, 68, 69].”

    From Psychotherapeutic interventions in individuals at risk for Alzheimer’s dementia: a systematic review (2022) · cites this paper as [68]

    The Introduction (Choice of comparator; page unavailable) describes a health-education program with psychoeducational components for people with SCD, supporting this paper as an example of such an approach. But this is a trial-design paper: its Abstract (Results; page unavailable) describes outcomes to be assessed, not outcome data. It also does not establish the citing sentence’s count of four research groups. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • All 6 papers focusing on interventions for individuals with SCD were carried out within randomized controlled trials.

    “All were carried out within randomized controlled trials [55, 56, 61, 66, 68, 69].”
  • A total of four research groups described psychoeducational interventions for individuals with SCD alone or in combination with cognitive training and CBT-based interventions and MBSR-based interventions.

    “A total of four research groups described psychoeducational interventions alone [61] or in combination with cognitive training and CBT-based interventions [66] and MBSR-based interventions [55, 56, 68, 69]”
  • Existing quantitative data did not show significant effects on mood of MBSR-based interventions as compared to control conditions.

    “Though existing quantitative data did not show significant effects on mood of MBSR-based interventions as compared to control conditions [46, 47, 55–58, 68, 69]”

    From Psychotherapeutic interventions in individuals at risk for Alzheimer’s dementia: a systematic review (2022) · cites this paper as [68]

    The Introduction (Mindfulness-based intervention and Choice of comparator; page unavailable) describes prior evidence that mindfulness-based interventions may reduce anxiety, but does not report the claimed lack of significant effects on mood versus controls. The Abstract (Results; page unavailable) describes outcomes to be assessed in this trial, not comparative findings. I searched for prior mood results and statistical comparisons; our copy does not establish the claimed null effect. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
