Item Development of a complex intervention package for dengue prevention(Ministry of Health, Sri Lanka, 2022) Rajapaksha, R.M.N.U.; Abeysena, C.; Balasuriya, A.; PannilaHetti, N.; Alagiyawanna, A.; Manilgama, S.INTRODUCTION: Complex interventions are widely used in public health practices with noteworthy health impacts. Communication for Behavioural Impact (COMBI) plan is an effective method directed at enacting behaviour change to benefit health and social development which encourage precise behavioural outcomes and is effective in planning a behavioural change for dengue control. The aim of this study was to develop an intervention package to change the behaviour to prevent dengue in one of the highest dengue-endemic areas of Sri Lanka. METHODS: The development of the intervention package was formulated according to the two phases, the ‘Theoretical phase’ and ‘Modelling phase’ of the framework for ‘Developing and Evaluating Complex Interventions’. World Health Organization’s 10 key steps in planning COMBI strategies were followed in order to develop the present intervention package. A situational market analysis was conducted in the highest dengue-endemic area in Kurunegala district to identify the Specific Behavioural Objectives (SBOO) for the COMBI plan. The development of the COMBI plan was conducted using the mixed methodological approach including quantitative and qualitative designs. RESULTS: The overall goal of the COMBI plan was to decrease the morbidity and mortality due to dengue illness by improving the dengue prevention behaviours among householders. The SBOO for the plan were to improve the proper waste management practices according to the ‘3R concept’ (Reduce, Reuse and Re-cycling) and to improve the dengue prevention practices by 30 minutes of weekly cleaning. The strategies of intervention package were to conduct a community empowerment program to improve household waste management and weekly practices on dengue prevention by conducting administrative mobilization and public relationship, public advocacy, community mobilization, personal selling, advertising, and point of service promotion during follow-up. CONCLUSION: Developing a COMBI plan for an area after the identification of SBOO would be feasible to implement in order to empower the community to prevent dengue and improve community health services.Item Cross-cultural adaptation and validation of the Sinhala version of the hospital anxiety and depression scale (HADS) for patients diagnosed with ischemic heart disease (IHD) in Sri Lanka(College of Community Physicians of Sri Lanka, 2023) Gamage, C.K.W.; de Zoysa, P.; Balasuriya, A.; Fernando, N.; Jayamanne, D.INTRODUCTION: The Hospital Anxiety and Depression Scale (HADS) is a frequently used instrument to measure depression and anxiety symptoms among patients diagnosed with ischaemic heart disease (IHD). However, a Sinhala version of HADS for Sri Lankan IHD patients has not been validated in Sri Lanka. OBJECTIVES: To translate, cross-culturally adapt and validate the HADS in a Sinhala-speaking Sri Lankan population with IHD METHODS: The Sinhala translation of HADS was conducted in four phases: forward translation, backward translation, patient testing and proofreading with the Mapi Research Trust guidelines. Content and consensual validation of the translated scale was conducted with the Delphi method, and the ratings were evaluated for consensus. The validated scale was administered to a sample selected using systematic sampling of 140 IHD patients attending medical clinics at a base hospital in Sri Lanka. Factor structure was verified with Confirmatory Factor Analysis (CFA) and reliability with internal consistency by Cronbach's alpha. RESULTS: The HADS Sinhala version showed good content and consensual validity. CFA proved that the uncorrelated two-factor structure was compatible with the original instrument (x2=156.98; df=76; p<0.001). The Confirmatory Fit Index (CFI) was 0.89, and the Root Mean Square Error of Approximation (RMSEA) was 0.09. The reliability analysis indicated Cronbach's alpha for depression and anxiety as 0.86 and 0.83, respectively. CONCLUSIONS & RECOMMENDATIONS: The cross-culturally adapted HADS Sinhala version shows similar psychometric properties as the original instrument and can be used in future studies with confidence.Item Health seeking behaviours, dengue prevention behaviours and community capacity for sustainable dengue prevention in a highly dengue endemic area, Sri Lanka(BioMed Central, 2023) Rajapaksha, R.M.N.U.; Abeysena, C.; Balasuriya, A.INTRODUCTION: Dengue has become a major health problem in globally as well as locally. The delay in health-seeking is significantly associated with complications leading to severe dengue and active engagement of communities needs to minimize the delays in management to control epidemics. The aim of the study was to evaluate the relationship between sociodemographic characteristics and householders' Health-Seeking Behaviours (HSB), Dengue-Prevention Behaviours (DPB), and Community Capacities (CC) for sustained dengue prevention in Sri Lanka, a country with a high dengue endemicity. METHODS: A cross-sectional analytical study was carried out in a district with the highest dengue endemicity from January to April 2019. Of the householders, 532 were chosen randomly. A pre-tested, validated, and interviewer-administered questionnaire was used to assess HSB and DPB. The HSB was assessed using three aspects, initial response for fever management, the duration of blood testing and initial response if suspected dengue. The DPB assessment was evaluated using 'waste, outdoor water container, indoor water container, roof gutter and water storage management'. 'Dengue Community Capacity Assessment Tool', with 14 key items was used to assess the level of community capacity for dengue prevention. Out of the total, ≥ 50% was considered as an "adequate" HSB, DPB and CC. Multiple logistic regression was performed to control confounding effects. The results were expressed as adjusted Odds-Ratios (aOR) and 95% Confidence Intervals (CI). RESULTS: The response rate was 93.2% (n = 496). Among them, 44.6% (n = 221) had adequate overall HSB, and 19.2% (n = 95) had adequate DPB. Householders who have ≤ 4 family members are 1.74 times (aOR = 1.74; 95% CI: 1.17 - 2.61) more likely to have adequate HSB and 1.85 times (aOR = 1.85; 95% CI: 1.11 - 3.09) more likely to have adequate DPB. The age group of 46 to 70 years' individuals (aOR = 1.74; 95% CI:1.12 - 2.92), and who engaged in employment (aOR = 1.68; 95% CI: 1.05 - 2.67) were more likely to have adequate DPB than the group of 18 to 45 years and the non-employed individuals respectively. Of them, 24.6% (n = 122) perceived that they have adequate CC. The householders who have per-capita income < USD 50 are 1.95 times (aOR = 1.95; 95%CI:1.11 - 3.40) more likely to have adequate CC. CONCLUSION: The HSB, DPB and CC need to be improved to change the behaviour for sustainable dengue prevention and community capacity-building programmes need to be conducted in the Kurunegala district, Sri Lanka.Item Incidence management system of the healthcare institutions for disaster management in Sri Lanka(BioMed Central, 2023) Rajapaksha, N.U.; Abeysena, C.; Balasuriya, A.; Wijesinghe, M.S.D.; Manilgama, S.; Alemu, Y.A.BACKGROUND: Incident management systems and disaster planning processes facilitate maximal use of available resources. Evaluation of the Incident Command System (ICS) is one of the top five key areas of research priority in the field of surge. The study was aimed at assessing the disaster preparedness and ICS of the public healthcare institutions for the disaster management in a disaster-prone district of Sri Lanka. METHODS: A descriptive cross-sectional study was conducted among all public sector healthcare institutions (n = 74), including curative-healthcare institutions (n = 46) which have inward-care facilities for patient care and preventive healthcare institutions (n = 28) in Kurunegala district, Sri Lanka from May-September 2019 using a validated interviewer administered questionnaire which was based on 'CO-S-TR Model' for ICS assessment including 'Clear need for increased capacity (≤25%), Basic level (26 - 50%), Moderate level (51 - 75%) and High level (>75%)'.RESULTS: Focal points for disaster management were nominated by the majority of the curative sector (n = 33; 76.7%) and preventive sector (n = 19; 73.1%) healthcare institutions. A written disaster preparedness and response plans were available in 72% (n= 31) curative sector and 76% (n= 19) preventive sector institutions. The higher proportion of the curative sector institutions had moderate level capacity in the area of providing treatment, and basic level capacities were in the areas of 'staff mobilization, coordination of activities, supplying of special needs, triage of cases and transportation'. There is a clear need for improvement in the areas of communication commanding, management of controlling the incidence and tracking of the cases in the curative sector. The majority of the preventive sector institutions had moderate level capacity in commanding, control, coordination and tracking of cases. The basic level capacity in the areas of staff mobilization, stuff management and triage of cases. There is a clear need for improvement in the areas of communication in preventive sector. Of the public sector healthcare institutions, the higher proportion of the preventive sector (n = 20; 76.9%) and curative sector (n = 29; 67.4%) had basic level overall surge capacity of ICS for disaster management. CONCLUSION: Coordination, communication, commanding, management of controlling the incidence and tracking of cases following outbreaks need to be improved and capacity development programmes could implement to develop the preparedness for future disasters.Item Cross-cultural adaptation of the type D personality scale for use with patients diagnosed with Ischemic heart disease in Sri Lanka(The Sri Lanka Medical Association, 2021) Walpita Gamage, C.K.; de Zoysa, P.; Balasuriya, A.; Fernando, N.; Jayamanne, B.D.W.INTRODUCTION: Ischemic Heart Disease (IHD), a major cardiovascular disease globally, has become the primary cause of death in Sri Lanka. Negative affectivity (NA) and social inhibition (SI) are two personality traits which increase the risk of IHD. The Type D Scale (DS-14) evaluates a person’s general level of distress on NA and SI. However, DS-14 has not been translated and validated into Sinhala in Sri Lanka. OBJECTIVES: The study aimed to cross-culturally adapt and validate the DS-14 for use with Sinhala speaking patients diagnosed with IHD. METHODS: Translation, back translation and pre-test were conducted before a two-rounds of a Delphi process which assessed content and consensual validity of the instrument. The validated questionnaires were administered to 140 patients diagnosed with IHD at a Base Hospital. Factor structure was confirmed through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) and reliability, by internal consistency with Cronbach’s alpha. RESULTS: The questionnaire was administered among 140 participants (85 females), aged 18-60 years. The DS-14 Sinhala version showed good content and consensual validity. Factor analysis proved two factors compatible with the original instrument, which explained the variance of 62.9%. CFA confirmed the two-factor model. The reliability analysis indicated Cronbach’s alpha for NA and SI as 0.93 and 0.88, respectively. CONCLUSION: The cross-culturally adapted DS-14 Sinhala version indicated the same psychometric properties as the original instrument, in the local context with IHD patients. It can be confidently applied in the investigation of Type D personality in IHD prevention and treatment, as well as in research. KEYWORDS: Ischemic Heart Disease, Type D Personality, DS-14Item Effectiveness of a community based health educational intervention in reducing unmet need for modern methods of family planning among ever married reproductive age women in the Kalutara district, Sri Lanka(Insight Medical Publishing, 2012) Malwenna, L.I.; Jayawardana, P.L.; Balasuriya, A.INTRODUCTION: Unmet need is defined as the percentage of all fecund women who are married or living in union and thus presumed to be sexually active but are not using any method of contraception, either do not want to have any more children or want to postpone their next birth at least for two more years or do not know when or if they want another child 1. Unmet Need for Modern Methods includes all in the unmet need group and those who are using natural and traditional methods at the time of survey (The Westoff Model) 2. It describes the discrepancy between sexual and contraceptive behaviors and stated fertility preferences of women in the reproductive age. OBJECTIVE: This study was designed to evaluate the effectiveness of a health educational intervention in improving the knowledge and attitudes on family planning (FP) among Public Health Midwives (PHMM) who function as community health workers and acceptance of modern FP methods planning which eventually reduce the Unmet Need (UMN) and thereby reducing the risk of unintended pregnancy among 15 - 49 year old married women in in the Kalutara district. METHOD: Initially the perceptions on unmet need in community service providers was assessed by three Focus Group Discussions conducted among Medical Officers of Health, Public Health Nursing Sisters and PHMM. It was followed by assessment of the baseline knowledge and attitudes on FP and UMN among all the PHMM and a group of married women in reproductive age (15-49) with unmet need for modern methods selected from cluster sampling of PHM areas in the district using PPS technique, allocating 22 clusters of 12 women in each Intervention (IA) and Control Area (CA).The developed health education intervention was applied on PHMM followed by the selected group of women with unmet need for modern methods only to the IA. The effectiveness was assessed in terms of the change in knowledge and attitudes of PHMM after 2 months of intervention, of target group of women after 6 months of intervention and the reduction of unmet need for modern methods in the IA compared to CA. RESULT: In PHMM, overall percentage mean knowledge score in IA at pre and post intervention were 29.9% and 65.7% respectively with a statistically significant difference (p<0.001) but with no such difference (p=0.10) in CA between pre (20%) and post (30%) scores. Median attitude scores were 37.5% and 86% in IA at pre and post intervention with a statistically significant difference (p<0.001). For CA respective figures were (40%) and (41%) with no significant difference (p=0.09) Regarding the target group, in IA had pre (37.6%) and post (70.6%) mean knowledge scores with a statistically significant difference (p<0.001); but with no significant difference (p=0.06) in CA between pre (39.0%) and post (40.2%) scores. Similarly, between groups comparison shows statistically significant difference (p<0.001) between IA and CA in post intervention, the scores being 70.6% and 40.2% respectively. CONCLUSION: The training conducted on PHMM revealed a significant impact on knowledge and attitudes in both service providers and clients leading to change in the FP practice and reduction in unmet need for modern methods of FP.

The civilians were the most affected in the war with reports of scant respect for human rights on both sides of the warring factions. OBJECTIVE: To conduct a cross-sectional study to assess the prevalence of psychiatric morbidity among married females in two villages in Northern Sri Lanka that was affected significantly in the last phase of the war. METHOD: All married females in two resettled villages in the Mannar District were interviewed by trained data collectors using the translated K-10 and PSSR-17 questionnaires to estimate the prevalence of post-traumatic stress disorder (PTSD) and depressive disorder. All families in these villages were from internally displaced camps where they had been living for more than a year after having been displaced from their homes and having experienced direct war trauma for weeks. Data was collected from 135 married females between March to May 2011 with ethical approval for the study. RESULTS: Criteria for diagnosis of severe PTSD were met in 57% of all participants and all participants had at least mild symptoms of PTSD. The screening tool for depression showed 63% to have significant depressive symptoms. Both depressive and severe PTSD features were present in 24%. Nearly 73% of participants were having either depression or severe PTSD. CONCLUSION: Psychiatric morbidity was high in the post-conflict period, in a highly vulnerable population of married females.
