Application of the PRECEDE -PROCEED model in prevention of brucellosis focused on livestock vaccination process.

ABSTRACT: BACKGROUND:This article reports the steps of an educational intervention, which is designed to change livestock breeders' preventive behavior in terms of vaccinating their livestock against brucellosis. The study has been conducted in a rural area in a country with the second highest brucellosis prevalence in the world. METHODS:In a quasi-experimental study and applying PRECEDE-PROCEED model, 45 livestock breeders were trained through basket method, accompanied with constructive feedback from researchers and peers and a brief interactive lecture at the end. The livestock breeders' awareness, attitude and practice level in the intervention group was compared with those of other 45 livestock breeders in a control group, 1 and 6 months after the intervention. According to the results of the Rose Bengal tests (RBTs), as a rapid and simple screening test, the presence or absence of Brucella antibodies in the animals' serum was investigated. RESULTS:Immediately and 1 month after the intervention, the mean scores of knowledge, awareness and practice of livestock breeders in the intervention group were significantly higher. Six months after the intervention, the results of the RBTs were positive in more livestock in the intervention group compared to the animals in the control group. The positive result of RBT after educational intervention, in livestock whose test results were negative immediately before intervention, accompanying the results of observation indicating a good general condition of livestock was considered as a probable evidence of the success of the educational intervention. CONCLUSION:The model-driven educational intervention could significantly increase livestock breeders' awareness, attitude and practice regarding prevention of brucellosis and vaccination of their livestock against brucellosis; however, a period of non-continuous reinforcement and gradual reduction of the number of the reinforcements by health educator workers is recommended in order to increase the maintenance of the learnt behavior. TRIAL REGISTRATION:Conducting this study was registered at Iranian Registry of Clinical Trials ( IRCT20180304038945N1 ). Registered 24 December 2018. The proposal was registered before enrollment of the first participant.

Project description:BackgroundThe inadequate awareness of livestock breeders on brucellosis transmission, as well as their improper knowledge about preventing brucellosis is considered as one of the important barriers to animal vaccination against brucellosis. The present study aimed to design and validate a brucellosis prevention questionnaire focused on animal vaccination. The valid questionnaire was used to design, implement, and evaluate an interventional training program.MethodA brucellosis prevention questionnaire (BPQ) was developed in the exploratory psychometric study. In addition, face-to-face interviews were conducted to formulate its initial items, the results of which were merged with those obtained from literature review. Further, the face, content, and construct validity of the questionnaire were assessed by co-operating livestock breeders, veterinarians, and health educationists. The impact score (IS), and content validity ratio (CVR) and index (CVI) of the items were calculated, and the construct validity of the questionnaire was evaluated through factor analysis. Furthermore, the reliability of the results related to the questionnaire was measured by using Cronbach's alpha, intra-class correlation coefficient (ICC), and composite reliability, as well as the standard error of measurement (SEM).ResultsThe questionnaire was finalized with 53 items and its validity was confirmed by CVI (0.90), CVR (0.74), and IS (4.30). Additionally, the items were loaded into three constructs of awareness, attitude, and practice. Further, the predictive power of awareness, attitude, and practice was determined as 43.43, 15.81, and 15.78%, respectively. Furthermore, the fitness of the proposed model among the constructs was confirmed by the root mean square error of approximation (RMSEA) <?0.08, as well as normed chi-square (×?2/ df)?<?5.0, comparative fit index (CFI)???0.90, and Tucker- Lewis index (TLI)???0.9.ConclusionThe brucellosis prevention questionnaire represented acceptable psychometric properties. The factors influencing the preventive behavior of livestock breeders can be identified by applying the questionnaire, and co-operating veterinarians and educational planners.

Project description:IntroductionDrowning is a global public health threat, disproportionately impacting low-income and middle-income countries. In the Philippines, it is estimated that more than 5200 people die from drowning per annum. This number is likely to be higher than currently estimated with the inclusion of disaster-related and transportation-related drowning. Drowning is preventable if appropriate preventive interventions are put in place which redress known risk factors.Methods and analysisThis study uses the PRECEDE-PROCEED model (PPM), an eight-step health promotion planning and evaluation model for building and improving intervention programmes. This mixed-methods study, which can be used in any location, will be implemented in Los Baňos, Laguna, Philippines, identified as an area of concern for drowning. Using the PPM, data on drowning will be collected from death records, community observation, key informant interviews, focus group discussions and community survey. A range of analytical methods will be used to explore drowning data including univariate and χ2 analyses, analysis of variance, relative risk and calculating rates using population data. The quantitative data and themes drawn from qualitative data will be used to populate the first four phases of the PPM. Following the data collection, the remaining stages of the PPM will be designed and implemented in the barangay (village) with the highest drowning rate.Ethics and disseminationThis study has obtained ethical clearance from the University of the Philippines Manila Research Ethics Board (UPMREB 2017-425-01). Study findings will be disseminated through workshops and presentations to the local community as well as through peer-reviewed literature and conference presentations. The PPM has rarely been applied to drowning prevention and it is the aim that the study described in this protocol is expanded across other areas of the Philippines and to other countries with a high drowning burden to inform prevention efforts.

Project description:BackgroundThe prevalence of obesity in India is increasing at an alarming rate. Obesity-related mHealth apps have proffered an exciting opportunity to remotely deliver obesity-related information. This opportunity raises the question of whether such apps are truly effective.ObjectiveThe aim of this study was to identify existing obesity-related mHealth apps in India and evaluate the potential of the apps' contents to promote health behavior change. This study also aimed to discover the general quality of obesity-related mHealth apps.MethodsA systematic search for obesity-related mHealth apps was conducted in both the Google Play Store and the Apple App Store. The features and quality of the sample apps were assessed using the Mobile Application Rating Scale (MARS) and the potential of the sample apps' contents to promote health behavior change was assessed using the PRECEDE-PROCEED Model (PPM).ResultsA total of 13 apps (11 from the Google Play Store and 2 from the Apple App Store) were considered eligible for the study. The general quality of the 13 apps assessed using MARS resulted in mean scores ranging from 1.8 to 3.7. The bivariate Pearson correlation between the MARS rating and app user rating failed to establish statistically significant results. The multivariate regression analysis result indicated that the PPM factors are significant determinants of health behavior change (F3,9=63.186; P<.001) and 95.5% of the variance (R2=0.955; P<.001) in the dependent variable (health behavior change) can be explained by the independent variables (PPM factors).ConclusionsIn general, mHealth apps are found to be more effective when they are based on theory. The presence of PPM factors in an mHealth app can greatly influence the likelihood of health behavior change among users. So, we suggest mHealth app developers consider this to develop efficient apps. Also, mHealth app developers should consider providing health information from credible sources and indicating the sources of the information, which will increase the perceived credibility of the apps among the users. We strongly recommend health professionals and health organizations be involved in the development of mHealth apps. Future research should include mHealth app users to understand better the apps' effectiveness in bringing about health behavior change.

Project description:Introduction:Brucellosis is one of the most prevalent diseases in Torbate Heidarieh, Iran; it is a common disease between human and animals. The present study aimed to review the psychometric properties of a questionnaire on brucellosis prevention behaviors based on the PRECEDE model among rural farmers and their family members (PRECEDE-QBPB). Materials and Methods:The study was a combination of qualitative and quantitative stages. In the qualitative stage, an 86-item questionnaire including interviews with 30 farmers, their family members and other effective people, as well as literature review, was designed. In the quantitative stage, psychometric properties of the PRECEDE-QBPB including the face, content, and constructs validities, as well as reliability measurement of the questionnaire were evaluated. Item impact, content validity ratio (CVR) and content validity index (CVI) for all items were calculated. Besides, confirmatory factor analysis (CFA) was done to evaluate the construct's validity; AMOS 20 was used for this purpose. In this stage, a cross-sectional study was conducted on 500 rural farmers and their family members. To estimate the internal consistency of this questionnaire, Cronbach's alpha was used for each variable. Further, descriptive statistics and Kaiser-Meyer-Olkin and Bartlett's test of sphericity were used to describe the characteristics of the participants and collect samples, respectively. Results:Based on the results of face validity and content validity (CVR, CVI and CFA 9), 19 and 22 items were removed, respectively, leaving the final questionnaire with 36 items and eight subscales including knowledge, attitude, self-efficacy, social support, enabling factors, environmental factors, behavioral factors, and reinforcing factors. The Cronbach's coefficient alpha was calculated for the total questionnaire (?= 0.92, 0.69-0.87 for subscales). The evaluation of model fit indices showed that all indices confirmed the suitability of the final model fit; therefore, the questionnaire has suitable construct validity. Conclusion:A questionnaire, as a valid tool, was designed in the present study. Healthcare providers, policymakers, planners, researchers may use this tool to find a comprehensive understanding of enabling, reinforcing, environmental and behavioral factors that affect brucellosis before implementing health education and health promotion programs.

Project description:PurposeThe PRECEDE-PROCEED model (PPM) is a community-based participatory research (CBPR) framework for health promotion, yet the direct application of the PPM into practice is unclear. This paper describes how the PPM was adapted for the development and application of a pilot intervention study to promote outdoor physical activity (PA) in older adults (OUTDOOR ACTIVE). We illustrate the steps and adaptations we applied to put the PPM into practice and present the developed interventions.DesignThe PPM was adapted by incorporating a socio-ecological model. This ensured the design of any resultant intervention would explicitly address multi-level determinants of physical activity. The list of possible program components to select from for the design of an intervention was also extended.SettingBremen, Germany.ParticipantsParticipants in the intervention development were 924 noninstitutionalized older adults, aged 65-75 years (response: 25.2%), living in Bremen-Hemelingen, Germany. For implementation of the intervention and to ensure sustainability, several groups of stakeholders were involved throughout the process.MethodsA mixed method design was employed (e.g., focus groups, quantitative survey) to identify determinants. A round table and participatory workshops were held to involve the target group and community stakeholders in the design of an intervention using the adapted PPM model.ResultsA conceptual model was developed illustrating the integration of a socio-ecological model into the PPM. The model received ecological validity, as it was affirmed by community stakeholders as an appropriate method for designing a community-level PA intervention. Target goals to address PA determinants were selected by target group members. An intervention to meet the goals was developed and implemented with target group input.ConclusionThe adapted PPM is a promising starting point for developing multi-level interventions. Steps should be taken to ensure all social groups are participating in the process and all levels of determinants are addressed.
