Abstract

Background The Illness Cognition Questionnaire (ICQ; Evers et al., J Consult Clin Psychol, 69:1026-1036, 2001) assesses three ways of cognitively evaluating the stressful and aversive character of a chronic illness: helplessness, acceptance, and perceived benefits.Purpose The purpose of this study was to evaluate the construct validity of the ICQ in individuals with chronic pain and patients with chronic fatigue.Method The ICQ was administered to 821 individuals with chronic pain and 295 patients with chronic fatigue. Confirmatory factor analyses were performed to assess the hypothesized three-factor structure, containing the factors "helplessness," "acceptance," and "perceived benefits." A multigroup analysis was performed to investigate the stability of the factor structure in both groups.Results Results confirmed the three-factor structure in the two samples. The factor structure was invariant across individuals with chronic pain and chronic fatigue.Conclusion As the three-factor structure provided a good fit in both groups, we confirm the usefulness of the subscale scores in research and clinical practice.

  • The ICQ is a reliable and valid instrument, with a Cronbach's alpha of 0.90 for the acceptance subscale.

    “The ICQ is a reliable and valid instrument, with a Cronbach's alpha of 0.90 for the acceptance subscale [16, 28].”

    From Cognitive behavior therapy in patients with chronic fatigue syndrome: The role of illness acceptance and neuroticism. (2013) · cites this paper as [28]

    Section 3.1 (p. 10) reports good internal consistency for the ICQ subscales in both groups, with values ranging from .81 to .91; the paper also supports the questionnaire’s construct validity. Our copy does not identify .90 as the Cronbach’s alpha for the acceptance subscale, so the specific value is not verified. (LLM, conf=0.84)

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.
