Dimensionality of the Whiteley Index: Assessment of hypochondriasis in an Australian sample of primary care patients
Abstract
Objective The Whiteley Index (WI) is a widely used instrument for measuring hypochondriacal worries and beliefs. Several studies explored the structural validity of the WI obtaining contrary results concerning the number of factors as well as the item composition. The main aim of this study is to compare factor solutions from previous studies to draw conclusions about the most valid scale model of the WI for administration in primary care.Methods Weighted least squares (WLS) confirmatory factor analyses of the WI were conducted. The sample in study consisted of 1800 patients from primary care practices. Seven different models were compared, including single- and three-factor conceptualisations.Results A seven-item, single-factor model best described the data, while three-factor models were clearly inadequate.Conclusions Results support a one-dimensional conceptualisation of the WI and suggest a certain subscale of the WI, the WI-7, to constitute the most psychometrically sound scale for use as a screening instrument for hypochondriasis in primary care. In addition to psychometric considerations, the brevity and simplicity of the WI-7 also make it attractive as a screening tool in the context of primary care. A cutoff score of 2/3, calculated on the basis of general practitioners' diagnoses, yielded the best balance of sensitivity and specificity in the present study.

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.
