Psychometric properties of the Malay version of the Illness Cognition Questionnaire among cancer patients in Malaysia
Open accessAbstract
OBJECTIVE: The Illness Cognition Questionnaire (ICQ) was translated from its original English version to the Malay version for this research, adapted the Malay language version of the ICQ (ICQ-M) for use in cancer patients, and assessed the internal consistency, content, face, construct, convergent, discriminant and concurrent validity of the ICQ-M among a cohort of cancer patients with mixed cancer types in Malaysia. METHOD: Initially, the ICQ was translated into Malay and back-translated, and its content and face validity were evaluated. Then, 346 cancer patients with various cancer types received the ICQ-M, and its internal consistency, convergent, discriminant, construct, and concurrent validity were evaluated. RESULTS: The ICQ-M and its domains had acceptable internal consistency with Cronbach's α ranging from 0.742 to 0.927. Construct validity assessment demonstrated that the ICQ-M consists of 17 items designated in two domains with good convergent and discriminant validity. The ICQ-M and its domains also had moderate correlations with the Acceptance and Action Questionnaire II, which denotes that the ICQ-M had acceptable concurrent validity. CONCLUSION: The ICQ-M had good psychometric properties and is now available to measure the illness cognition of cancer patients in Malaysia.

The ICQ-M is suitable for measuring disease acceptance in Malay-speaking breast cancer patients.
“The ICQ-M’s reliability and validity make it suitable for measuring disease acceptance in Malay-speaking breast cancer patients [33].”
From Effectiveness of Acceptance and Commitment Therapy (ACT) on disease acceptance for breast cancer patients: Study protocol of a randomized controlled trial (2024) · cites this paper as [33]
The Results (Reliability of the ICQ-M) report acceptable internal consistency, and the Discussion reports validity for an acceptance-and-perceived-benefits domain. But the Participants section shows that breast cancer patients were part of a mixed-cancer sample; the paper does not establish reliability and validity specifically for Malay-speaking breast cancer patients or for disease acceptance as a separate domain. No page numbers are available in our copy. (LLM, conf=0.85)

The Abstract Results report acceptable internal consistency and validity for the ICQ-M, and the Discussion describes its use in assessing acceptance. However, the Abstract Method says the validation involved 346 patients with various cancer types, not a breast-cancer-specific sample; the paper therefore does not establish those psychometric findings specifically for breast cancer patients. No page numbers are available in our copy. (LLM, conf=0.86)
Experimental — accuracy not yet measuredConstruct validity of the ICQ-M was supported by factor analysis, confirming 17 items across two domains with good convergent and discriminant validity.
“Construct validity was supported by factor analysis, which confirmed the structural integrity of the questionnaire, comprising 17 items distributed across two domains with good convergent and discriminant validity.”

Concurrent validity of the ICQ-M was evidenced by moderate correlations with the AAQ-II.
“Additionally, concurrent validity was evidenced by moderate correlations with the Acceptance and Action Questionnaire II (AAQ-II), indicating that the ICQ-M effectively measures the intended constructs in relation to similar tools.”

Content validity of the ICQ-M was high, as evaluated by a panel of experts.
“Content validity was evaluated by a panel of experts who rated the relevance of each item, resulting in high item-level and scale-level content validity indices (I-CVI and S-CVI), affirming the appropriateness of the ICQ-M items.”

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.
