“…The inclusion of survivors with recurrent disease may have inflated the results of the current study because these individuals were likely allocated to the pessimistic IPs group and inevitably had poorer health outcomes. Furthermore, our composite BIPQ scale was based on a factor structure that was similar to that of other studies, [22][23][24][25] but does not support the theoretical model by Leventhal et al that presents emotional and cognitive representations as distinct factors. 33 As a consequence, the groups in the current study were not only based on cognitive perceptions regarding disease severity, such as perceptions of how long the disease will continue, but also on emotional representations.…”

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.

“…The scale most widely used is the Illness Perception Questionnaire (IPQ), validated with a sample of patients with chronic diseases (asthma, liver, and diabetes), is made up of 38 items. The nine-item brief version (BIP-Q) [16], has also been widely used [12,22,23]. The original questionnaire measures identity, cause, timeline, consequences, and control/cure.…”

“…The original questionnaire measures identity, cause, timeline, consequences, and control/cure. Studies have proven the usefulness of both the original version and the brief questionnaire for exploring perception of the disease in different areas of health [12,16,23,24]. Later, Moss-Morris et al [17] revised the original questionnaire to extend it to the cognitive and affective dimensions of disease perception in the Illness Perception Questionnaire Revised (IPQ-R) with 70 items.…”

The ravages caused by the disease known as COVID-19 has led to a worldwide healthcare and social emergency requiring an effective combined effort from everyone to reduce contagion. Under these circumstances, the perception of the disease is going to have a relevant role in the individual's psychological adjustment. However, at the present time there is no validated instrument for evaluating adult perception of threat from COVID-19. Considering the importance of perception or representation of the disease in a state of social alert, our study intended to validate an instrument measuring the psychological process of the disease caused by the coronavirus . In view of the above, this study evaluated the factor structure and reliability of the version of the Illness Perception Questionnaire (IPQ) for COVID-19 in a sample of adults. The sample consisted of 1014 Spanish adults (67.2% women and 32.8% men). The exploratory and confirmatory factor analyses supported a unidimensional model of the scale, which was the one that showed the best fit and explained 43.87% of the variance. This brief version has adequate psychometric properties and may be used to evaluate the perception of threat from COVID-19 in an adult Spanish population. The validation of this instrument contributes to progress in representation of COVID-19 in our culture.

“…Similarly, B-IPQ has been validated for different conditions and languages [29][30][31][32][33][34], although only lately translated to Swedish for use in adolescents with ADHD [14]. The B-IPQ [21] covers five domains: identity, timeline, cause, control and consequences [35][36][37][38][39].…”

Objectives: The purpose of this study was to assess the reliability and validity of Swedish translations of the Beliefs about Medicines Questionnaire-Specific (BMQ-Specific) and Brief Illness Perception Questionnaire (B-IPQ) for use in adolescents with ADHD. Methods: Forward and backward translations of the BMQ-Specific and B-IPQ scales to Swedish were conducted and reviewed by adolescents with ADHD and professionals. The validity and reliability of both questionnaires were investigated in a cross-sectional study of 101 adolescents (13-17 years) on a long-term prescription of ADHD medication recruited from two child and adolescent psychiatric outpatient clinics in Sweden. Results: Regarding the BMQ-Specific, principal component analysis (PCA) loadings confirmed the previously defined components of Specific-Necessity and Specific-Concern. The PCA for B-IPQ revealed two components, the first one, B-IPQ Consequences, captured questions regarding perceptions of the implication of having ADHD (items 1, 2, 5, 6 and 8) and the second one, B-IPQ-Control, the perceptions of the capability to manage the ADHD disorder (items 3, 4 and 7). The Cronbach alpha coefficients for BMQ-Specific-Necessity scale was a ¼ 0.80, for BMQ-Specific-Concern scale a ¼ 0.75, B-IPQ Consequences a ¼ 0.74 and for B-IPQ-Control a ¼ 0.44. Conclusions: The present results prove the Swedish translation of BMQ-Specific and B-IPQ to be valid and reliable for utilization in adolescents with ADHD. The PCA confirmed the original components for BMQ-Specific and the recent findings of two main B-IPQ components describing emotional and cognitive implications versus the capability for self-care maintenance of ADHD.
