Abstract

Perceived dyscognition or fibrofog has been ranked as one major contributor of distress in fibromyalgia (FM). The Multidimensional Inventory of Subjective Cognitive Impairment (MISCI) was devised as a brief and comprehensive self‐report measure of cognitive function in FM. The main objective of the present study was to assess the psychometric properties of the Spanish version of the MISCI. One hundred and twenty patients with FM were included, and dimensionality, reliability, and validity of the MISCI were evaluated. Data from brain imaging (N = 61) were also used in validity analyses. Known‐groups validity was evaluated by including a subset of 45 patients without FM in partial/total remission from depression. Sensitivity to change was assessed after a mindfulness‐based intervention. Spanish version of the MISCI exhibited a one‐factor structure, excellent internal consistency, and good convergent validity with symptomatology and gray matter volumes in anterior and middle cingulate cortices. Significant improvements in MISCI scores after a mindfulness‐based intervention were reported. An additive effect of FM and depression regarding MISCI scores was also observed. Self‐reported depression, anxiety, and problems in balance predicted the 38% of the MISCI variance. The Spanish version of the MISCI is a valuable instrument to include in FM research and clinical practice.

  • Fibromyalgia patients often have cognitive impairment (fibrofog) that can hinder understanding and application of intervention concepts.

    “on the other hand, cognitive impairment that entails difficulties in abilities such as attention and memory, referred to as fibrofog, which could hinder their understanding and application of the concepts of the intervention [17].”

    From Attachment-Based Compassion Therapy for Reducing Anxiety and Depression in Fibromyalgia (2022) · cites this paper as [17]

    The Introduction reports that cognitive complaints are common in fibromyalgia, include memory and concentration difficulties, and are termed fibrofog. It does not say that fibrofog hinders patients’ understanding or application of intervention concepts; that consequence is an extrapolation. (LLM, conf=0.87)

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.
