“…35 Increasingly patients with head and neck cancer will become long-term survivors. Consistent with previous studies, 21,36 illness perception dimensions were intercorrelated. Patients reporting more symptoms also perceived their condition to be more serious, reported greater illness concern and emotional impact and poorer understanding of illness.…”

“…19 In 109 patients with idiopathic Parkinson's disease, although positive illness perceptions were associated with better wellbeing, optimism was a significant moderator of that relationship. 20 In studies of cancer, more optimistic patients tend to report less negative illness perceptions 14,21 and lower anxiety and depression as well. [22][23][24] Being mostly crosssectional, confounding and reverse causality cannot be excluded in some of the preceding studies.…”

Background Leventhal's commonsense model implies illness perceptions influence illness outcomes. This study examined illness perceptions among head and neck cancer survivors, and whether these predicted subsequent psychological distress. Methods A total of 124 survivors of head and neck cancer (87% nasopharyngeal carcinoma; NPC) completed measures of psychological distress (Hospital Anxiety and Depression Scale; HADS), illness perceptions (Brief Illness Perception Questionnaire; B‐IPQ), dispositional optimism (revised Chinese version of the Life Orientation Test; C‐LOT‐R), and clinical and demographic data approximately12.9 months after diagnosis (T1). Six months later (T2) psychological distress (HADS) was again measured. Adjusted multivariate analyses tested whether illness perceptions predicted T2 HADS scores. Results Illness perception dimensions were significantly intercorrelated (0.01‐0.68), explaining 8.0% of anxiety and 4.8% of depression symptom variability at T2. After adjustment for T1 distress, illness identity (β = 0.270, P < .01) and sex identification as a woman (β = 0.275, P < .01) predicted T2 anxiety symptoms while illness identity (β = 0.195, P < .05), unemployment (β = 0.195, P < .05), and pessimism (β = –0.227, P < .01) predicted T2 depression symptoms. Conclusion Perceived illness identity predicted psychological distress, accounting for modest levels of distress variance. Unresolved symptoms may exacerbate distress.

“…37,38 In addition, we found that higher cancer stage and more comorbidities were associated with having pessimistic IPs. Consistent with literature regarding threatening IPs, pessimistic IPs were found to be associated with sociodemographic factors, including younger age, being female, and having a low educational level.…”

Optimistic IPs are associated with better HRQOL and survival, even if they may appear to be unrealistic with respect to cancer survivors' prognosis. Survivors with pessimistic IPs appear to have the worst outcomes. Therefore, efforts are needed to provide better support to patients with pessimistic IPs to improve their outcomes.

“…Construct validity was assessed by correlating B-IPQ scores with physical symptom distress (MSAS-PHYS) and psychological distress (HADS-Anxiety and HADS-Depression) scores. We hypothesized that the B-IPQ would correlate with greater physical symptom distress and psychological distress [27]. All correlation was performed by Pearson’s correlation analysis.…”

ObjectiveThe eight-item Brief Illness Perception Questionnaire (B-IPQ) supposedly evaluates cognitive and emotional representations of illness. This study examined the validity and reliability of a traditional Chinese version of the B-IPQ in Hong Kong Chinese breast cancer survivors.Methods358 Chinese breast cancer survivors who had recently ended their primary treatment completed this B-IPQ Chinese version. Confirmatory factor analysis (CFA) tested the factor structure. The internal consistency, construct, predictive and convergent validities of the scale were assessed.ResultsCFA revealed that the original three-factor (cognitive-emotional representations and illness comprehensibility) structure of the B-IPQ poorly fitted our sample. After deleting one item measuring illness coherence, seven-item gave an optimal two-factor (cognitive-emotional representations) structure for the B-IPQ (B-IPQ-7). Cronbach’s alpha for the two subscales were 0.653 and 0.821, and for the overall seven-item scale of B-IPQ was 0.783. Correlations of illness perception and physical symptom distress, anxiety, depression and known-group comparison between different treatment status suggested acceptable construct validity. The association between baseline illness perception and psychological distress at 3-month follow up supported predictive validity.ConclusionsB-IPQ-7 appears to be a moderately valid measure of illness perception in cancer population, potentially useful for assessing illness representations in Chinese women with breast cancer.
