Abstract:
Research has found that some individuals magnify their symptoms. This study investigated the psychometric properties of a new questionnaire, the Personal Problems Questionnaire (PPQ), which aims to screen for cognitive, emotional and physical symptoms and identify patients who present with non-valid symptoms, flagging up the need for a more comprehensive assessment. Demographic data were collected from 77 participants with chronic pain. The PPQ was administered alongside the Short Form McGill Pain Questionnaire (SFMPQ; Melzak, 1987) and the Medical Symptom Validity Test (MSVT; Green, 2004), a brief test of effort. A subsample (27 participants) also completed the Personality Assessment Inventory (PAl; Morey, 2007). Additionally, secondary analysis was performed on the sample of 410 healthy community participants used for the norming of the PPQ to explore its scales' underlying factors and internal reliability. Separate exploratory factor analyses on the PPQ scales in the clinical and healthy controls norming samples identified two factors. The internal reliability of the scales of the PPQ was good in the chronic pain sample (a > 0.80) and in the healthy norming community sample (all scales except for the Neurological Symptoms scale a > 0.70). Concurrent validity for several clinical and for all the validity scales of the PPQ was supported by exploring their association with the PAl, SF-MPQ and MSVT. Furthermore, the PPQ Non-Valid Physical Scale was able to predict mean MSVT score. Sensitivity and specificity of PPQ validity scales were calculated using the cut-off derived from the simulation study and the MSVT as reference criterion. The PPQ is the first British-developed self-report questionnaire that includes a measure of symptom validity. The results of this study suggest that the PPQ holds promise as a screening tool for emotional, physical and cognitive symptoms.
