Until now, the benefits of diagnosing hypertension have been far more reported than the harms. To obtain the net result of the preventive interventions for cardiovascular disease, such as diagnosing and treating mild hypertension, assessing benefits and harms in the most comprehensive way possible is necessary, including the psychosocial consequences of labelling. When measuring psychosocial consequences of labelling hypertension, a questionnaire with high content validity and adequate psychometric properties is needed. Objectives The aim of this study was to describe the psychometric parameters of face and content-validated pool of items. Other objectives were also to screen the item pool by using Rasch model analysis and confirmatory factor analysis (CFA) for identifying such items with sufficient fit to the hypothesised models. Methods We surveyed the pool of items as a draft questionnaire to Brazilians recruited via social networks, sending e-mails, WhatsApp (R) messages and posting on Facebook (R). The inclusion criteria were to be older than 18 years old, to be healthy and to have only hypertension. We used Rasch model analysis to screen the item pool, discarding items that did not fit the hypothesised domain. We searched for local dependence and differential item functioning. We used CFA to confirm the derived measurement models and complementarily assessed reliability using Cronbach's coefficient alpha. Results The validation sample consisted of 798 respondents. All 798 respondents completed Part I, whereas 285 (35.7%)-those with hypertension-completed Part II. A condition-specific questionnaire with high content validity and adequate psychometric properties was developed for people labelled with hypertension. This measure is called 'Consequences of Labelling Hypertension Questionnaire' and covers the psychosocial consequences of labelling hypertension in two parts, encompassing a total of 71 items in 15 subscales and 11 single items. Conclusion We developed a tool that can be used in future research involving hypertension, especially in scenarios of screening, prevention, population strategies and in intervention studies. Future use and testing of the questionnaire may still be required.

- Development of an item pool for a questionnaire on the psychosocial consequences of hypertension labelling(2019) GYURICZA, Janos Valery; D'OLIVEIRA, Ana Flavia Pires Lucas; MACHADO, Lucas Bastos Marcondes; BRODERSEN, JohnBackground Hypertension is the most prevalent risk factor for cardiovascular disease globally. Roughly one-third of the adult population has hypertension. However, most people diagnosed with hypertension do not benefit from blood pressure control with pharmacologic interventions: they are overdiagnosed and overtreated and might experience negative psychosocial consequences of being labelled. These consequences are relevant outcomes that need to be assessed and validly measured to identify all benefits and harms related to interventions designed to prevent cardiovascular disease. Objectives To develop a pool of items with high content validity for a draft version of a condition-specific questionnaire to measure the psychosocial consequences of being labelled with mild hypertension. Methods We selected relevant items from existing Consequences of Screening (COS) questionnaires. These items belonged to two groups: COS core items and potential condition-specific items. All items were originally in Danish and were translated into Brazilian Portuguese using the dual-panel method. Individual and group interviews were conducted with people with mild hypertension and low risk for cardiovascular disease, and were designed to test the translated items for face and content validity and were also used to generate new relevant items. Structured individual interviews were conducted to categorise all the items into domains. Results The Brazilian Portuguese dual-panel translation of both groups of items was found to be relevant for adults diagnosed with hypertension. We generated 52 new items to achieve high content validity. The result was a set of 132 items divided into 22 domains in 2 parts. Part I was directed at the general population, whereas part II was directed only at people diagnosed with hypertension and it consisted of 38 items in 8 domains. Twelve items remained as single items. High content validity was achieved with the pool of 132 items divided into 22 domains in 2 parts. Discussion High content validity was achieved for a condition-specific questionnaire measuring the psychosocial consequences of being labelled with mild hypertension. This instrument encompassed 132 items divided into 22 domains in 2 parts. Thereby, a draft of the Consequneces of Hypertension questionnaire (COH) was developed. The psychometric properties of this questionnaire will be discussed in a diferent paper.
