Item Effectiveness of a community-based participatory health promotion intervention to address knowledge, attitudes and practices related to intimate partner violence: a quasi-experimental study(BioMed Central, 2024) Reyal, H.P.; Perera, M.N.; Guruge, G.N.D.BACKGROUND Intimate partner violence is the most common form of violence experienced by women. It has detrimental consequences. A range of determinants cause intimate partner violence and to reduce it, effective interventions are required to address the determinants. Health promotion interventions have been recommended as effective to enable people to control over the determinants and to improve health. Hence, a community based participatory health promotion intervention was developed and tested in a selected study setting. The objective was to evaluate the effectiveness of a health promotion intervention in terms of addressing knowledge, attitudes and practices related to intimate partner violence.METHODS A quasi-experimental study was conducted by recruiting ninety women aged 15 to 49 years separately from two health administrative areas identified as the intervention area and the control area from the Kandy district of Sri Lanka. A pretested interviewer-administered questionnaire was used in both pre- and post-assessments. Selected groups of women from the intervention area were facilitated with a health promotion intervention to improve knowledge, attitudes and practices related to intimate partner violence. To evaluate the effectiveness of the intervention descriptive summaries and bivariate analysis were used.RESULTS The response rate was 90.9% (N = 90) during the pre-assessment and 87.9% (n = 87) and 82.8% (n = 82) from the intervention and control areas, respectively, during the post-assessment. Statistically significant improvement was reported in the total mean score comprising knowledge, attitudes, practices and identification of determinants from 59.6 to 80.8 in the intervention area [Pre-assessment: Mean = 59.6 (standard deviation-SD) = 17.5; Post-assessment: Mean = 80.8, SD = 19.0; p < 0.001) compared to the improvement in the control area from 62.2 to 63.0 (Pre-assessment: Mean = 62.2, SD = 17.3; Post-assessment: Mean = 63.0, SD = 18.9; p = 0.654).CONCLUSIONS The intervention was effective to improve knowledge, attitudes and practices related to intimate partner violence. Hence, the present approach can be used in similar contexts to address the knowledge, attitudes and certain practices related to intimate partner violence.Item Prediction of colorectal cancer risk among adults in a lower middle-income country(AME Publishing Company, 2019) Samarakoon, Y.M.; Gunawardena, N.S.; Pathirana, A.; Perera, M.N.; Hewage, S.A.BACKGROUND: Globally, colorectal cancer (CRC) is ranked as the third most common cancer in men and the second in women. Use of a simple, validated risk prediction tool will offer a low-cost mechanism to identify the high-risk individuals for CRC. This will increase efficient use of limited resources and early identification of patients. The aim of our study was to develop and validate a risk prediction model for developing CRC for Sri Lankan adults. METHODS: The risk predictors were based on the risk factors identified through a logistic regression model along with expert opinion. A case control design utilizing 65 CRC new cases and 65 hospital controls aged 30 years or more was used to assess the criterion validity and reliability of the model. The information was obtained using an interviewer administered questionnaire based on the risk prediction model. RESULTS: The developed model consisted of eight predictors with an area under the curve (AUC) of 0.849 (95% CI: 0.8 to 0.9, P<0.001). It has a sensitivity of 76.9%, specificity of 83.1%, positive predictive value (PPV) of 82.0%, negative predictive value (NPV) of 79.3%. Positive and negative likelihood ratios are 4.6 and 0.3. Test re-test reliability revealed a Kappa coefficient of 0.88. CONCLUSIONS: The model developed to predict the risk of CRC among adults aged 30 years and above was proven to be valid and reliable and it is an effective tool to be used as the first step to identify the high-risk population who should be referred for colonoscopy examination. © Journal of Gastrointestinal Oncology.
