“…Each subscale is added up with a higher score representing more positive attitude, stronger normative belief, or greater barriers perceived by patients [8]. Originally, the DSRQ was developed among 174 patients with heart failure using factorial validity (3 factors extracted with 54.2% of variance) and internal consistency (a ¼ .62e.88) for reliability [8]; however, it was also reliable among a Brazilian sample with hypertension with Cronbach's alpha coefficient ranging from .41 to .85 [9].…”

“…It is a practical and simple tool that can help researchers and clinicians to assess patient adherence in a relatively short time and is simple and easy to use [8,12]. Even though the DSRQ was established among patients with heart failure, it is also reliable and can do doable duty as an assessment tool for hypertensive patients [9]. The personal beliefs are integrated inside the subscale of DSRQ which highlights individual perceptions of adherence related to sodium restriction.…”

The purpose of this research was to test the validity and reliability of the Indonesian version of the Dietary Sodium Restriction Questionnaire (DSRQ-I) among patients with hypertension. Methods: The cross-sectional study enrolled hypertensive patients from a cardiac outpatient department in Indonesia using convenience sampling. Eligible patients received a demographic questionnaire and DSRQ-I during a one-month period of data collection. Content and construct analysis examined the validity, whereas internal consistency assessment checked reliability. Participation required 10e 15 minutes on average. Results: One hundred thirty-five patients participated: mostly females (54.1%) and married (82.9%) with mean age of 58.18 ± 10.44 years. The item of content validity index was .97, and subscale content validity index was .81 for DSRQ-I. The KaisereMeyereOlkin test gave a value of .83, indicating adequate sampling, and the Bartlett's test of sphericity reached significant result (p < .001). The principal component analysis indicated three components, with 64.2% explaining variance, including perceived behavioral control (35.5%), attitude (19.3%), and subjective norm (9.4%). Confirmatory factor analysis produced a parsimonious model on the three-factor outcome by removing a single item. The indices of good fit model was achieved at c 2 /df ¼ 2.17, goodness fit index ¼ .85, root mean square error of approximation ¼ .09, standardized root mean square means ¼ .07, and Bentler comparative fit index ¼ .90 (p < .001). Cronbach's alpha coefficients for attitude, subjective norm, and perceived behavioral control were .85, .87, and .85, respectively. All interitem and item-total correlations indicated adequate outcome and acceptable result. Consequently, 15 items were determined reliable measurement and included in the final version of DSRQ-I. Conclusion:The DSRQ-I is a valid and reliable instrument to measure facilitators and barrier of sodium restriction among hypertensive patients in Indonesia.

“…The DSRQ was adapted to Brazilian Portuguese [28] and validated for heart failure (HF) [29] to help identifying facilitators and barriers to sodium-restriction adherence, and to be useful in clinical practice to guide the development of educational and counseling interventions to patients [19]. Considering the importance of assessing salt-restriction adherence and the lack of instruments for easy application in the care routine, the DSRQ was validated for hypertension [21] with the purpose of being an instrument to assess low-sodium diet adherence which can contribute to the planning of educational interventions in patients with hypertension.…”

BackgroundThe effectiveness of nonpharmacological interventions in blood pressure reduction has been evidenced by several studies. Nevertheless, as adherence to a low-sodium diet is poor, interventions regarding habit changing should be of a motivational nature in order to develop the ability of overcoming obstacles regarding sodium-restriction behavior.The present study aims to describe the protocol and randomization of a clinical trial design in order to evaluate the effectiveness of an educational intervention based on Dietary Sodium Restriction Questionnaire (DSRQ) scores. The effectiveness measures are the DSRQ score variation and reduction in urinary sodium values from baseline to after 2 and 6 months.Methods/designThis parallel, randomized clinical trial will include 120 participants, recruited and randomized as follows: 60 of them to be allocated to a sodium-restriction educational intervention group whose results are based on the DSRQ application; and the other 60 allocated to a control group with usual care. Educational orientation and usual care sessions will be conducted once a month for a period of 6 months. Both spot urine collection – estimating sodium intake – and the DSRQ will be applied at the baseline, in the eighth week and at the end of the follow-up. There will also be blood collection and 24-h ambulatory blood pressure monitoring (ABPM) at the beginning and end of the follow-up. Anthropometric measurements, blood pressure measurement and 24-h food recall will be collected during follow-up.DiscussionThe study “The effectiveness of an educational intervention to sodium restriction in patients with hypertension” is based on the results of the DSRQ application, whose objective is to evaluate aspects related to nonadherence to the recommendation of a low-sodium diet, identifying adherence barriers and facilitators, contributing to the planning of interventions for improving the adoption of a low-sodium diet and, consequently, hypertension control.Trial registration numberClinicalTrials.gov, Identifier: NCT02848690.

“…The participants will answer the following questionnaires: Dietary Sodium Restriction Questionnaire (DSRQ) [25] for the assessment of sodium-restriction adherence; Self-Care of Hypertension Inventory – Brazilian Version (SC-HI) [26, 27] to measure self-care in hypertension patients; Medication Assessment Questionnaire [MAQ] [28] to evaluate adherence to drug therapy; International Physical Activity Questionnaire (IPAQ) [29] to quantify the level of physical activity; and the Epworth Sleepiness Scale (ESS) [30] to measure daytime sleepiness. All questionnaires will be administered at baseline and at the end of follow-up.…”

Background Only one-third of hypertensive patients achieve and maintain blood-pressure control. This is attributed to low treatment adherence and has a negative impact on clinical outcomes. Adherence is multidimensional and involves aspects both related to patient characteristics and to the chronic nature of the disease. In this context, motivational interviewing has been proposed as an approach to foster patients’ motivations to change their behavior for the benefit of their own health, thus providing more lasting behavioral changes. Design and methods Single-center, parallel, randomized controlled trial with outcome-assessor blinding. This study will select adult patients ( n = 120) diagnosed with hypertension who receive regular follow-up in a specialized outpatient clinic. Patients will be randomly allocated across two groups: the intervention group will have appointments focused on motivational interviewing, while the control group will have traditional appointments. Patients will be monitored face-to-face, once monthly for six months. The primary outcomes will be a reduction of at least 8 mmHg in systolic blood pressure and changes in mean blood pressure measured by 24-h ambulatory blood pressure monitoring. Secondary outcomes include improvement of adherence to a low-sodium diet, adherence to self-care behaviors, regular use of antihypertensive medications, increase or maintenance of physical activity, weight reduction, evaluation of changes in daytime sleepiness, and cessation of smoking. Discussion This study shows an intervention strategy that will be tested and, if effective, warrant replication in monitoring of other chronic diseases.
