Abstract
As COVID-19 cases surge around the world, public health authorities are looking for effective strategies to influence individuals to follow COVID-19 prevention guidelines. However, limited empirical research was conducted to identify the factors behind individuals' compliance with COVID-19 prevention guidelines. This research proposed an integrated model based on the theory of planned behavior and norm activation theory to explain compliance towards COVID-19 prevention guidelines. Data from a survey of 652 individuals were used to test the proposed integrated model. Results showed that three factors: personal norms, attitude towards compliance- behavior, and perceived behavior control, directly influence compliance with COVID-19 prevention guidelines. Awareness of the risk of the COVID-19 pandemic and feelings of responsibility in the COVID-19 fight drives social and moral obligations, respectively, and also influences compliance behavior. The findings of this study not only contribute to theory development in health compliance behavior but also provide practical guidance to health authorities and policymakers on how to enhance compliance behavior with COVID-19 prevention measures.

Abstract
This study developed a conceptual framework for a preventive travel decision-making process amidst the COVID-19 pandemic, combining the Health Belief Model (HBM) and Value-Belief-Norm (VBN). Analyzing 409 responses collected from an online survey, this study verified the integrated model as a salient theory addressing the importance of social components and health belief factors in affecting behavior. The model revealed that altruistic value influences the HBM variables, whereas personal norms mediate preventive behaviors and beliefs in both VBN and HBM. These findings offer new theoretical insights into decision-making process and provide practitioners with effective crisis management strategies concerning pro-social and health beliefs.

The Validity of the Theory of Planned Behaviour for Understanding People's Beliefs and Intentions toward Reusing Medicines. PHARMACY 2021; 9:pharmacy9010058. [PMID: 33803406 PMCID: PMC8006004 DOI: 10.3390/pharmacy9010058] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 02/19/2021] [Accepted: 03/03/2021] [Indexed: 02/04/2023] Open
Abstract
Background: many factors can impact a person’s behaviour. When the behaviour is subject to prediction, these factors can include, for example, the perceived advantages and disadvantages of performing the behaviour, normative beliefs, and whether the behaviour is thought to be achievable. This paper examines intentions to engage in medicines reuse, i.e., to accept medicines that are returned unused to a pharmacy to be reused. The paper aims to outline the validity of the Theory of Planned Behaviour (TPB) for understanding people’s intentions to engage in medicines reuse by examining this against other long-standing health-related psychological theories of behavioural change. Thus, the Health Belief Model (HBM), Protection Motivation Theory (PMT), Trans-Theoretical Model of Health Behaviour Change (TTM/SoC), Theory of Reasoned Action (TRA), and TPB are examined for their application in the study of medicines reuse. Discussion: the HBM, PMT, TTM/SoC, TRA, and TPB were assessed for their relevance to examining medicines reuse as a behaviour. The validity of the TPB was justified for the development of a Medication Reuse Questionnaire (MRQ) to explore people’s beliefs and intention toward reusing medicines. Conclusion: TPB has been widely used inside and outside of health-related research and it was found to have more accurately defined constructs, making it helpful in studying medicines reuse behaviour.

Abstract
BACKGROUND The effectiveness of malaria chemoprophylaxis is limited by a lack of compliance in travellers. This study assesses the demographic, travel-related, and psychosocial determinants of non-compliance with chemoprophylaxis. METHODS 715 adults, who received a pre-travel malaria prophylaxis prescription, were invited to complete a post-travel digital questionnaire on non-compliance, demographics, travel-related and psychosocial variables. RESULTS 330 travellers (53% response) reported 32% non-compliance with malaria chemoprophylaxis. Logistic regression analyses revealed that 3/11 assessed psychosocial variables uniquely predicted non-compliance: 'negative attitude towards chemoprophylaxis' (β=0.694, OR 2.0, p<0.01), 'low perceived severity of malaria' (β=0.277, p=0.04) and 'fatigue during travel' (β=2.225, OR 9.3, p<0.01). Furthermore, the age and education of the traveller were uniquely predictive of non-compliance (β=-0.023 (p=0.02) and β=0.684 (p=0.04)). None of the travel-related variables predicted non-compliance. CONCLUSIONS About one-third of the travellers in our study were non-compliant with malaria prophylaxis, especially young travellers and highly educated travellers. Fatigue during travel seems to lead to non-compliance. Further research should focus on addressing the psychosocial factors in pre-travel consultation, since these appear to be better predictors for intention to comply than travel-related variables.

Abstract
Older travellers are at higher risk of malaria-related morbidity and mortality compared with younger people. Yet, prevention of malaria in this specific group of travellers is a long-standing issue in travel medicine. The aim of this research was to synthetize the existing evidence about this important topic, highlighting older travellers' attitudes and practises toward malaria prevention. Searches were performed on PubMed, Embase, EuropePMC, Web of Science, WHOLIS and LILACS databases for relevant studies reporting malaria prevention measures in older travellers. To measure malaria prevention in the older traveller population, the main information outcomes were obtained from the ABCD framework that included travellers' 'Awareness' towards pre-travel health advice, their utilisation of 'Bite-prevention measures' and adherence to 'Chemoprophylaxis'. Data on 'Diagnosis'-related outcomes were excluded for not being measures of malaria prevention. Three evaluators independently selected studies, extracted data and assessed the quality of the included articles. The research protocol was registered with PROSPERO (protocol number CRD42019124202). Out of the 899 titles and abstracts screened, 13 articles were included in this review synthesis. These studies included a wide range of interventions for malaria prevention: no relevant differences in pre-travel healthcare attendance were found depending on age; older travellers were found to be less likely to comply with bite-prevention measures; three high-quality studies reported that adherence to chemoprophylaxis significantly increased with age, while three studies did not find age-related differences in travellers' adherence. Overall, prevention of malaria in the older traveller has received limited attention from the scientific community. Older travellers seem to be less likely to comply with bite-prevention measures, but there was high heterogeneity across the reports. This population group demands particular attention and tailored health advice before travelling to malaria endemic areas. More research is required on how to improve malaria prevention in the older traveller.

Abstract
BACKGROUND Mefloquine is one of four antimalarial agents commonly recommended for preventing malaria in travellers to malaria-endemic areas. Despite its high efficacy, there is controversy about its psychological side effects. OBJECTIVES To summarize the efficacy and safety of mefloquine used as prophylaxis for malaria in travellers. SEARCH METHODS We searched the Cochrane Infectious Diseases Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL), published on the Cochrane Library; MEDLINE; Embase (OVID); TOXLINE (https://toxnet.nlm.nih.gov/newtoxnet/toxline.htm); and LILACS. We also searched the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP; http://www.who.int/ictrp/en/) and ClinicalTrials.gov (https://clinicaltrials.gov/ct2/home) for trials in progress, using 'mefloquine', 'Lariam', and 'malaria' as search terms. The search date was 22 June 2017. SELECTION CRITERIA We included randomized controlled trials (for efficacy and safety) and non-randomized cohort studies (for safety). We compared prophylactic mefloquine with placebo, no treatment, or an alternative recommended antimalarial agent. Our study populations included all adults and children, including pregnant women. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the eligibility and risk of bias of trials, extracted and analysed data. We compared dichotomous outcomes using risk ratios (RR) with 95% confidence intervals (CI). Prespecified adverse outcomes are included in 'Summary of findings' tables, with the best available estimate of the absolute frequency of each outcome in short-term international travellers. We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS We included 20 RCTs (11,470 participants); 35 cohort studies (198,493 participants); and four large retrospective analyses of health records (800,652 participants). Nine RCTs explicitly excluded participants with a psychiatric history, and 25 cohort studies stated that the choice of antimalarial agent was based on medical history and personal preference. Most RCTs and cohort studies collected data on self-reported or clinician-assessed symptoms, rather than formal medical diagnoses. Mefloquine efficacyOf 12 trials comparing mefloquine and placebo, none were performed in short-term international travellers, and most populations had a degree of immunity to malaria. The percentage of people developing a malaria episode in the control arm varied from 1% to 82% (median 22%) and 0% to 13% in the mefloquine group (median 1%).In four RCTs that directly compared mefloquine, atovaquone-proguanil and doxycycline in non-immune, short-term international travellers, only one clinical case of malaria occurred (4 trials, 1822 participants). Mefloquine safety versus atovaquone-proguanil Participants receiving mefloquine were more likely to discontinue their medication due to adverse effects than atovaquone-proguanil users (RR 2.86, 95% CI 1.53 to 5.31; 3 RCTs, 1438 participants; high-certainty evidence). There were few serious adverse effects reported with mefloquine (15/2651 travellers) and none with atovaquone-proguanil (940 travellers).One RCT and six cohort studies reported on our prespecified adverse effects. In the RCT with short-term travellers, mefloquine users were more likely to report abnormal dreams (RR 2.04, 95% CI 1.37 to 3.04, moderate-certainty evidence), insomnia (RR 4.42, 95% CI 2.56 to 7.64, moderate-certainty evidence), anxiety (RR 6.12, 95% CI 1.82 to 20.66, moderate-certainty evidence), and depressed mood during travel (RR 5.78, 95% CI 1.71 to 19.61, moderate-certainty evidence). The cohort studies in longer-term travellers were consistent with this finding but most had larger effect sizes. Mefloquine users were also more likely to report nausea (high-certainty evidence) and dizziness (high-certainty evidence).Based on the available evidence, our best estimates of absolute effect sizes for mefloquine versus atovaquone-proguanil are 6% versus 2% for discontinuation of the drug, 13% versus 3% for insomnia, 14% versus 7% for abnormal dreams, 6% versus 1% for anxiety, and 6% versus 1% for depressed mood. Mefloquine safety versus doxycyclineNo difference was found in numbers of serious adverse effects with mefloquine and doxycycline (low-certainty evidence) or numbers of discontinuations due to adverse effects (RR 1.08, 95% CI 0.41 to 2.87; 4 RCTs, 763 participants; low-certainty evidence).Six cohort studies in longer-term occupational travellers reported our prespecified adverse effects; one RCT in military personnel and one cohort study in short-term travellers reported adverse events. Mefloquine users were more likely to report abnormal dreams (RR 10.49, 95% CI 3.79 to 29.10; 4 cohort studies, 2588 participants, very low-certainty evidence), insomnia (RR 4.14, 95% CI 1.19 to 14.44; 4 cohort studies, 3212 participants, very low-certainty evidence), anxiety (RR 18.04, 95% CI 9.32 to 34.93; 3 cohort studies, 2559 participants, very low-certainty evidence), and depressed mood (RR 11.43, 95% CI 5.21 to 25.07; 2 cohort studies, 2445 participants, very low-certainty evidence). The findings of the single cohort study reporting adverse events in short-term international travellers were consistent with this finding but the single RCT in military personnel did not demonstrate a difference between groups in frequencies of abnormal dreams or insomnia.Mefloquine users were less likely to report dyspepsia (RR 0.26, 95% CI 0.09 to 0.74; 5 cohort studies, 5104 participants, low certainty-evidence), photosensitivity (RR 0.08, 95% CI 0.05 to 0.11; 2 cohort studies, 1875 participants, very low-certainty evidence), vomiting (RR 0.18, 95% CI 0.12 to 0.27; 4 cohort studies, 5071 participants, very low-certainty evidence), and vaginal thrush (RR 0.10, 95% CI 0.06 to 0.16; 1 cohort study, 1761 participants, very low-certainty evidence).Based on the available evidence, our best estimates of absolute effect for mefloquine versus doxycyline were: 2% versus 2% for discontinuation, 12% versus 3% for insomnia, 31% versus 3% for abnormal dreams, 18% versus 1% for anxiety, 11% versus 1% for depressed mood, 4% versus 14% for dyspepsia, 2% versus 19% for photosensitivity, 1% versus 5% for vomiting, and 2% versus 16% for vaginal thrush.Additional analyses, including comparisons of mefloquine with chloroquine, added no new information. Subgroup analysis by study design, duration of travel, and military versus non-military participants, provided no conclusive findings. AUTHORS' CONCLUSIONS The absolute risk of malaria during short-term travel appears low with all three established antimalarial agents (mefloquine, doxycycline, and atovaquone-proguanil).The choice of antimalarial agent depends on how individual travellers assess the importance of specific adverse effects, pill burden, and cost. Some travellers will prefer mefloquine for its once-weekly regimen, but this should be balanced against the increased frequency of abnormal dreams, anxiety, insomnia, and depressed mood.

Abstract
OBJECTIVES Combination antiretroviral therapy (cART) for HIV is widely available in sub-Saharan Africa. Adherence is crucial to successful treatment. This study aimed to apply an extended theory of planned behaviour (TPB) model to predict objectively measured adherence to cART in Tanzania. DESIGN Prospective observational study (n = 158) where patients completed questionnaires on demographics (Month 0), socio-cognitive variables including intentions (Month 1), and action planning and self-regulatory processes hypothesised to mediate the intention-behaviour relationship (Month 3), to predict adherence (Month 5). MAIN OUTCOME MEASURES Taking adherence was measured objectively using the Medication Events Monitoring System (MEMS) caps. Model tests were conducted using regression and bootstrap mediation analyses. RESULTS Perceived behavioural control (PBC) was positively (β = .767, p < .001, R2 = 57.5%) associated with adherence intentions. Intentions only exercised an indirect effect on adherence (B = 1.29 [0.297-3.15]) through self-regulatory processes (B = 1.10 [0.131-2.87]). Self-regulatory processes (β = .234, p = .010, R2 = 14.7%) predicted better adherence. CONCLUSION This observational study using an objective behavioural measure, identified PBC as the main driver of adherence intentions. The effect of intentions on adherence was only indirect through self-regulatory processes, which were the main predictor of objectively assessed adherence.

Abstract
Treatment regimens for conditions such as hypertension and Type II diabetes require strict adherence to medical instructions. Yet, adherence among patients living with chronic medical conditions attending public health clinics is typically low. The present study sought to determine the extent to which the Theory of Planned Behaviour (TPB) was able to significantly explain variance in adherence intentions and behaviour in a sample of 117 formerly disadvantaged South Africans living with diabetes and hypertension in the Western Cape. The results showed that the linear combination of TPB variables — Attitudes, Perceived behavioural control, and Subjective norms — was able to account for 47 per cent of the variance in adherence intentions and 23 per cent of the variance in self-reported adherence behaviour. The addition of the variables Psychological distress and Social support to the two regression models, hypothesised to add predictive power to the TPB, yielded non-significant results. The findings of the study are discussed in the context of applying theoretical models of behaviour developed in the industrially developed world and tested on middle-class subjects to patient samples in developing countries such as South Africa. Our findings suggest that social cognitive models of health behaviour such as the TPB may be useful in predicting treatment adherence but should be used in a critical and cautious manner.

Abstract
AIM The aim was to examine patients' stated preferences to persist with medicines and to explore the influence of psychosocial and sociocognitive factors. METHODS Community-dwelling, hypertensive patients recruited from nine European countries were invited to complete a discrete choice experiment (DCE) with attributes for treatment benefits, mild yet common adverse drug reactions (ADRs), rare but potentially life-threatening ADRs and dosing frequency. Patients responded to the binary choice of which medicine would they be most likely to continue taking. Data were analyzed using a random effects logit model. RESULTS Two thousand five hundred and forty-nine patients from Austria (n = 321), Belgium (n = 175), England (n = 315), Germany (n = 266), Greece (n = 288), Hungary (n = 322), the Netherlands (n = 231), Poland (n = 312) and Wales (n = 319) completed the DCE. All attributes significantly influenced patients' stated preference to persist with medications (P < 0.05). Patients were willing to accept decreases in treatment benefits of 50.6 percentage points (95% CI 46.1, 57.9) for a very rare (as opposed to rare) risk of severe ADR, 28.3 percentage points (95% CI 25.2, 33.1) for a once daily instead of twice daily dosing and 0.74 percentage points (95% CI 0.67, 0.85) for a 1% point reduction in mild ADRs. Models accounting for psychosocial and sociocognitive characteristics were significantly different from the base case. CONCLUSION Patients' intention to persist with treatment was associated with their willingness to trade potential benefits, harms and dosing frequency. Psychosocial and sociocognitive factors influenced the extent of trading. The utility model may have value in assessing patients' likelihood of persisting with medicines and to tailor treatment to maximize persistence.

Abstract
Two studies explored the relationship between past behavior, personality traits, intentions, and behavior. Study 1 (N = 181) considered intentions to engage in goal-directed activity (health protection). Cognitions specified by the Theory of Planned Behavior were examined as mediators of the relationship between past behavior, personality, and intentions. The effect of conscientiousness on intention was partially mediated by cognitions, whereas the effect of past behavior was partially mediated by cognitions and conscientiousness. Study 2 (N = 123) examined predictions of intentions and self-reported behavior in relation to both health protection and exercise, a more specific behavior. In both cases, the effect of conscientiousness on intention was totally mediated, whereas the effect on behavior was partially mediated. Similarly, the effects of past behavior on intentions were totally mediated, whereas the effects on behavior were partially mediated by cognitions and conscientiousness. Thus, combining personality traits and cognitions provided a more sufficient account of the determinants of intentions and behavior.

Abstract
Purpose
– The purpose of this paper is to investigate how the information about haze, a term used in China to describe the air pollution problem, is portrayed on Chinese social media by different types of organizations using the theoretical framework of the health belief model (HBM).
Design/methodology/approach
– A content analysis was conducted based on the 756 posts retrieved from Sina Weibo, the top microbloging platform in China, following the simple random sampling method. χ2 analysis was conducted to examine the relationships across the three types of organizations (governmental organizations, non-governmental organizations, and corporations) and the use of the HBM concepts (perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, and cues to action) in terms of haze and its threat to health.
Findings
– The results of this study indicated that corporations posted more Weibo messages categorized as perceived benefit and most of these posts are related to their products, while governmental organizations posted fewer Weibo messages categorized as perceived severity.
Social implications
– This study provides health decision makers and media consumers with knowledge about how to use social media more effectively in terms of haze-related issues.

Holmes EAF, Hughes DA, Morrison VL. Predicting adherence to medications using health psychology theories: a systematic review of 20 years of empirical research. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2014; 17:863-876. [PMID: 25498782 DOI: 10.1016/j.jval.2014.08.2671] [Citation(s) in RCA: 94] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/31/2013] [Revised: 05/27/2014] [Accepted: 08/01/2014] [Indexed: 06/04/2023]
Abstract
OBJECTIVES This review sought to identify the empirical evidence for the application of models from sociocognitive theory, self-regulation theory, and social support theory at predicting patient adherence to medications. METHODS A systematic review of the published literature (1990-2010) using MEDLINE, EMBASE, Cochrane Library, CINAHL, and PsychINFO identified studies examining the application of health psychology theory to adherence to medication in adult patients. Two independent reviewers extracted data on medication, indication, study population, adherence measure, theory, model, survey instruments, and results. Heterogeneity in theoretical model specification and empirical investigation precluded a meta-analysis of data. RESULTS Of 1756 unique records, 67 articles were included (sociocognitive = 35, self-regulation = 21, social support = 11). Adherence was most commonly measured by self-report (50 of 67). Synthesis of studies highlighted the significance (P ≤ 0.05) of self-efficacy (17 of 19), perceived barriers (11 of 17), perceived susceptibility (3 of 6), necessity beliefs (8 of 9), and medication concerns (7 of 8). CONCLUSIONS The results of this review provide a foundation for the development of theory-led adherence-enhancing interventions that could promote sustainable behavior change in clinical practice.

Abstract
BACKGROUND On behalf of the Public Health Agency of Canada, the Committee to Advise on Tropical Medicine and Travel (CATMAT) developed the Canadian Recommendations for the Prevention and Treatment of Malaria Among International Travellers for Canadian health care providers who are preparing patients for travel to malaria-endemic areas and treating travellers who have returned ill. OBJECTIVE To provide guidelines on risk assessment and prevention of malaria. METHODS CATMAT reviewed all major sources of information on malaria prevention, as well as recent research and national and international epidemiological data, to tailor guidelines to the Canadian context. The evidence-based medicine recommendations were developed with associated rating scales for the strength and quality of the evidence. RECOMMENDATIONS Used together and correctly, personal protective measures (PPM) and chemoprophylaxis very effectively protect against malaria infection. PPM include protecting accommodation areas from mosquitoes, wearing appropriate clothing, using bed nets pre-treated with insecticide and applying topical insect repellant (containing 20%-30% DEET or 20% icaridin) to exposed skin. Selecting the most appropriate chemoprophylaxis involves assessment of the traveller's itinerary to establish his/her malaria risk profile as well as potential drug resistance issues. Antimalarials available on prescription in Canada include chloroquine (or hydroxychloroquine), atovaquone-proguanil, doxycycline, mefloquine and primaquine.

Abstract
BACKGROUND Studies have shown patient attitudes to be an important predictor for health related behaviours including medication adherence. It is less clear whether patient attitudes are also associated with medication adherence among patients with psychoses. METHOD We conducted a systematic review and meta analysis of the data of studies that tested the association of attitude measures with medication adherence among patients with psychoses. 14 studies conducted between 1980 and 2010 were included. RESULTS Results show a small to moderate mean weighted effect size (r (+) = 0.25 and 0.26 for Pearson and Spearman correlations, respectively). CONCLUSIONS Theory based interventions that target potentially modifiable attitude components are needed to assess the relationship between positive patient attitudes and adherence behaviours among patients with psychoses.

Abstract
BACKGROUND The elimination of malaria in Zanzibar is highly dependent on sustained effective coverage of bed-nets to avoid malaria resurgence. The Health Belief Model (HBM) framework was used to explore the perceptions of malaria and bed-net use after a noticeable reduction in malaria incidence. METHODS Nineteen in-depth interviews were conducted with female and male caretakers of children under five in North A district, Zanzibar. Deductive content analysis was used to identify meaning units that were condensed, coded and assigned to pre-determined elements of the HBM. RESULTS Awareness of malaria among caretakers was high but the illness was now seen as easily curable and uncommon. In addition to the perceived advantage of providing protection against malaria, bed-nets were also thought to be useful for avoiding mosquito nuisance, especially during the rainy season when the malaria and mosquito burden is high. The discomfort of sleeping under a net during the hot season was the main barrier that interrupted consistent bed-net usage. The main cue to using a bed-net was high mosquito density, and children were prioritized when it came to bed-net usage. Caretakers had high perceived self-efficacy and did not find it difficult to use bed-nets. Indoor Residual Spraying (IRS), which was recognized as an additional means of mosquito prevention, was not identified as an alternative for bed-nets. A barrier to net ownership was the increasingly high cost of bed-nets. CONCLUSIONS Despite the reduction in malaria incidence and the resulting low malaria risk perceptions among caretakers, the benefit of bed-nets as the most proficient protection against mosquito bites upholds their use. This, in combination with the perceived high self-efficacy of caretakers, supports bed-net usage, while seasonality interrupts consistent use. High effective coverage of bed-nets could be further improved by reinforcing the benefits of bed-nets, addressing the seasonal heat barrier by using nets with larger mesh sizes and ensuring high bed-net ownership rates through sustainable and affordable delivery mechanisms.

Abstract
BACKGROUND The effectiveness of anti-vectorial malaria protective measures in travellers and expatriates is hampered by incorrect compliance. The objective of the present study was to identify the determinants of compliance with anti-vectorial protective measures (AVPMs) in this population that is particularly at risk because of their lack of immunity. METHODS Compliance with wearing long clothing, sleeping under insecticide-impregnated bed nets (IIBNs) and using insect repellent was estimated and analysed by questionnaires administered to 2,205 French military travellers from 20 groups before and after short-term missions (approximately four months) in six tropical African countries (Senegal, Ivory Coast, Chad, Central African Republic, Gabon and Djibouti). For each AVPM, the association of "correct compliance" with individual and collective variables was investigated using random-effect mixed logistic regression models to take into account the clustered design of the study. RESULTS The correct compliance rates were 48.6%, 50.6% and 18.5% for wearing long clothing, sleeping under bed nets and using repellents, respectively. Depending on the AVPM, correct compliance was significantly associated with the following factors: country, older than 24 years of age, management responsibilities, the perception of a personal malaria risk greater than that of other travellers, the occurrence of life events, early bedtime (i.e., before midnight), the type of stay (field operation compared to training), the absence of medical history of malaria, the absence of previous travel in malaria-endemic areas and the absence of tobacco consumption.There was no competition between compliance with the different AVPMs or between compliance with any AVPM and malaria chemoprophylaxis. CONCLUSION Interventions aimed at improving compliance with AVPMs should target young people without management responsibilities who are scheduled for non-operational activities in countries with high risk of clinical malaria. Weak associations between compliance and history of clinical malaria or variables that pertain to threat perception suggest that cognition-based interventions referencing a "bad experience" with clinical malaria could have only a slight impact on the improvement of compliance. Further studies should focus on the cognitive and behavioural predictors of compliance with AVPMs.

Abstract
The theory of planned behaviour (TPB; Ajzen, 1991) has been used extensively to predict social and health behaviours. However, a critical test of the TPB is whether interventions that increased scores on the theory's predictors would engender behaviour change. The present research deployed a novel technique in order to provide this test. Statistical simulations were conducted on data for 30 behaviours (N=211) that estimated the impact of interventions that generated maximum positive changes in attitudes, subjective norms and perceived behavioural control (PBC) on subsequent intentions and behaviour. Findings indicated that interventions that maximized TPB variables had a substantial impact on behavioural intentions. Although TPB maximization increased the proportion of the sample that performed respective behaviours by 28% compared with baseline, the behaviour of a substantial minority of the sample (26%) did not change. The research also identified several interactions among TPB variables in predicting simulated intention and behaviour scores and investigated the mediating role of intentions in predicting behaviour.

Abstract
The Health Belief Model (HBM; Rosenstock, 1966) was constructed to explain which beliefs should be targeted in communication campaigns to cause positive health behaviors. The model specifies that if individuals perceive a negative health outcome to be severe, perceive themselves to be susceptible to it, perceive the benefits to behaviors that reduce the likelihood of that outcome to be high, and perceive the barriers to adopting those behaviors to be low, then the behavior is likely for those individuals. A meta-analysis of 18 studies (2,702 subjects) was conducted to determine whether measures of these beliefs could longitudinally predict behavior. Benefits and barriers were consistently the strongest predictors. The length of time between measurement of the HBM beliefs and behavior, prevention versus treatment behaviors, and drug-taking regimens versus other behaviors were identified as moderators of the HBM variables' predictive power. Based on the weakness of two of the predictors, the continued use of the direct effects version of the HBM is not recommended.

Abstract
BACKGROUND To describe the epidemiology and trends of imported malaria in the Netherlands from 2000 through 2007. METHODS Based on national surveillance data regarding all reported infections of imported malaria, diagnosed 2000 through 2007, incidence and trends of imported malaria in the Netherlands were estimated. Travellers statistics were used to estimate incidence, and data on malaria chemoprophylaxis prescriptions were used to estimate the number of unprotected travellers. RESULTS Importation of malaria to the Netherlands is declining even as more travellers visit malaria-endemic countries. On average, 82% were acquired in sub-Saharan Africa, and 75% were caused by Plasmodium falciparum. The overall incidence in imported falciparum malaria fell from 21.5 to 6.6/10,000 of unprotected travellers. The percentage of unprotected travellers rose from 47% to 52% of all travellers. The incidence of imported falciparum infections is greatest from Middle and West Africa, and decreased from 121.3 to 36.5/10,000 travellers. The import of malaria from this region by immigrants visiting friends and relatives (VFR) decreased from 138 infections in 2000, to 69 infections in 2007. CONCLUSION The annual number of imported malaria shows a continuing declining trend, even with an increasing number of travellers visiting malaria endemic countries. VFR import less malaria than previously, and contribute largely to the declining incidence seen. The decline is not readily explained by increased use of chemoprophylaxis and may reflect a reduced risk of infection due to decreasing local malaria transmission as observed in some malaria endemic areas. Nevertheless, the increasing number of unprotected travellers remains worrisome.

Abstract
For those planning interventions based on social cognition models, it is usually not clear what impact on behaviour will follow from attempts to change the cognitions specified in these models. We describe a statistical simulation technique to assess the likely impact of health promotion targeting Theory of Reasoned Action (TRA)-based predictors of condom use. We apply regression-based simulation techniques to data from the SHARE project (n = 756 Scottish adolescents) to assess the potential impact of changes in cognitions on condom use. Results support the predictive utility of TRA-based models of psychological antecedents of condom use but also provide a cautionary warning about the magnitude of behaviour change likely to be achieved by interventions based on such models.

Abstract
INTRODUCTION In-line skating is increasing in popularity with a concomitant raise in the number of injuries associated with this activity. Studies have emphasized the value of protective gears in reducing the incidence of injuries and the subsequent need to identify the factors and processes involved in decision making about safety gear-wearing. The present study examined the contribution of the theory of planned behaviour (TPB) variables, and perceived susceptibility to and perceived severity of skating injury on the safety gear-wearing intention of adult skaters. METHODS Skaters (n=181) completed a questionnaire assessing the constructs of the TPB, perceived susceptibility to and perceived severity of skating injuries, and intention to wear safety gear. RESULTS Hierarchical regression analyses revealed significant contributions of instrumental attitude and subjective norm to the prediction of safety gear-wearing intention. In addition, perceived susceptibility to and perceived severity of injuries enhanced the prediction of intentions to wear safety gear over and above the contribution of TPB components. CONCLUSION As the TPB focuses only on behavioural evaluation, it seems promising to include threat perceptions in this theory as another aspect of health-related cognitions motivating intention formation about safety gear use. Practical implications for future campaigns and countermeasures are discussed.

Abstract
A meta-analysis investigated the effects of perceived injunctive (IN) and descriptive (DN) norms on behaviour (BEH) within the theory of planned behaviour (TPB) in a sample of 196 studies. Two related correlation matrices (pairwise and listwise) were synthesized from the data and used to model the TPB relations with path analyses. Convergent evidence indicated that the relation between DN and BEH was stronger than the relation between IN and BEH. Evidence also suggested a significant direct relation between DN and BEH in the context of TPB. A suppressor effect of IN on DN in its relation with BEH was also noted. Moderator analyses indicated that the DN-BEH relation was stronger when there was more time between measures of cognition and behaviour, when behaviours were not socially approved, more socially motive and more pleasant; results were mixed in the case of the IN-BEH relation. Results imply that IN and DN are conceptually different constructs.

Abstract
BACKGROUND With recent media attention to drug safety, patients may have heightened concerns about the side effects of medications that may affect their compliance with treatment. OBJECTIVES The purpose of this study was to determine the proportion of patients with type 2 diabetes mellitus who perceived having experienced side effects of antihyperglycemic medications, the proportion of these patients who communicated their concerns to physicians, and the potential association between the perception of experiencing side effects and adherence to medication regimens. METHODS Patients with diabetes were identified through the claims of a Midwest US managed care organization, using Health Plan Employer Data and Information Set criteria. Questionnaires were mailed to randomly selected patients. Patients receiving oral antihyperglycemic medications were selected as prospective subjects. Patients were excluded if they were receiving insulin. RESULTS The responses of 445 patients meeting the study criteria were collected and analyzed. The subjects were pre-dominantly white, with a mean (SD) age of 56 (11) years and a mean duration of diabetes of 7.3 (8.8) years. One hundred forty-eight (33%) subjects reported a perception of having experienced side effects of antihyperglycemic medication; 126 (85%) subjects reported that they had communicated these concerns to their physicians. Analysis of the subjects' responses indicated an association between the perception of having experienced side effects and nonadherence to antihyperglycemic medication regimens (beta=-0.15; P < 0.010). CONCLUSIONS Nearly one third of subjects with diabetes receiving oral noninsulin antihyperglycemic medications reported a perception of having experienced medication-related side effects. Despite the large portion of subjects who reported that they had communicated these concerns to their physicians, the perception of experiencing medication-related side effects was significantly associated with nonadherence to antihyperglycemic drug regimens.

Abstract
OBJECTIVES Interest has been growing in the use of the theory of planned behaviour (TBP) in health services research. The sample sizes range from less than 50 to more than 750 in published TPB studies without sample size calculations. We estimate the sample size for a multi-stage random survey of prescribing intention and actual prescribing for asthma in British general practice. To our knowledge, this is the first systematic attempt to determine sample size for a TPB survey. METHODS We use two different approaches: reported values of regression models' goodness-of-fit (the lambda method) and zero-order correlations (the variance inflation factor or VIF method). Intra-cluster correlation coefficient (ICC) is estimated and a socioeconomic variable is used for stratification. We perform sensitivity analysis to estimate the effects of our decisions on final sample size. RESULTS The VIF method is more sensitive to the requirements of a TPB study. Given a correlation of .25 between intention and behaviour, and of .4 between intention and perceived behavioural control, the proposed sample size is 148. We estimate the ICC for asthma prescribing to be around 0.07. If 10 general practitioners were sampled per cluster, the sample size would be 242. CONCLUSIONS It is feasible to perform sophisticated sample size calculations for a TPB study. The VIF is the appropriate method. Our approach can be used with adjustments in other settings and for other regression models.

Abstract
BACKGROUND Although bivariate relationships between depressive symptoms, health beliefs, and medication adherence have been identified, the complex relationship among these 3 constructs has not been explicated. OBJECTIVE This study examines the mediating role of patients' beliefs about diabetes and diabetes medications in relation to depressive symptoms and diabetes medication adherence. METHODS A survey was sent to 1700 persons with type 2 diabetes who were enrolled in a managed care organization in the United States. The bivariate relationships between depressive symptoms, diabetes-related health beliefs, and diabetes medication adherence were assessed. A structural equation model was developed to determine if health beliefs mediated the relationship between depressive symptoms and medication adherence. RESULTS Usable responses were received from 445 subjects. Greater depressive symptoms were associated with lower adherence to diabetes medications. The structural equation model indicated that the effect of depressive symptoms on medication adherence was mediated through perceived side effect barriers, perceived general barriers, and self-efficacy. Patients with severe depressive symptoms perceived more barriers to treatment adherence and were less confident in their ability to adhere to medication. In turn, reduced self-efficacy and heightened perceived barriers had a negative association with patients' adherence to diabetes medication regimens. CONCLUSIONS Decreased adherence to diabetes medications in patients with both diabetes and depressive symptoms may be partly explained by the association of depression with patients' beliefs about diabetes medications and their self-efficacy for medication use.

Abstract
AIMS Identifying patients' beliefs about taking medication can inform interventions to support medication taking, and their evaluation. We set out to establish the range of these beliefs, and measure the frequency of commonly held beliefs and their correlation with intention to take medication and self-reported medication adherence. METHODS An exploratory survey among Type 2 diabetic patients aged 40 years or older, registered in general practice, used a questionnaire measuring a range of plausible beliefs about taking and intention to take medication developed from interviews where belief elicitation was guided by the Theory of Planned Behaviour. The Medication Adherence Report Schedule was used as a self-report adherence measure. RESULTS Questionnaires were returned by 121 (61.7%) people. The majority strongly agreed with statements about the benefits of taking medication. Negative beliefs that taking medication would 'cause unpleasant side effects' and 'lead to weight gain' were held by 32.8 [corrected] and 13.9% of people, respectively. Beliefs about benefit were strongly associated with intention to take medication regularly. Two beliefs were associated with reduced medication adherence: 'changes to my daily routine would make it more difficult to take my diabetes medicines regularly' (P < 0.001), and 'if I were to take my diabetes medicines regularly this would lead to my gaining weight' (P < 0.01) [corrected] CONCLUSIONS Use of a theoretical model to elicit and identify common beliefs about taking medication regularly underscores the importance of exploring weight-gain concerns and how to keep taking tablets when routines change. Beliefs associated with intention and taking medication will inform intervention development, implementation and evaluation in randomized controlled studies.

Abstract
Intention certainty, past behavior, self-schema, anticipated regret, and attitudinal versus normative control all have been found to moderate intention-behavior relations. It is argued that moderation occurs because these variables produce "strong" intentions. Stability of intention over time is a key index of intention strength. Consequently, it was hypothesized that temporal stability of intention would mediate moderation by these other moderators. Participants (N = 185) completed questionnaire measures of theory of planned behavior constructs and moderator variables at two time points and subsequently reported their exercise behavior. Findings showed that all of the moderators, including temporal stability, were associated with significant improvements in consistency between intention and behavior. Temporal stability also mediated the effects of the other moderators, supporting the study hypothesis.

Abstract
BACKGROUND Drug abuse constitutes a worldwide problem. The purpose of this study was to investigate the characteristics of illicit drug use during long-term travel to the tropics, and to estimate the effects of antidrug brochures provided before travel on the use of drugs during travel. METHODS An interventional study was done on 1,000 travelers to the tropics aged 18 to 30 years. Pretravel brochures explaining the hazards of drug abuse were provided to 500 of them. A control group of 500 travelers did not receive the brochures. Questionnaires exploring drug abuse habits were sent to all travelers after their return. RESULTS Among 223 travelers (108 and 115 of the intervention and control groups, respectively) who returned their questionnaires, 82 (36.8%, 95% CI 30.5-43.5%) had experienced illicit drug use during their trip, whereas only 52 of them had tried drugs before (p<0.01). More travelers had used drugs in the Far East (43.3%) than in South America (25.6%, p< 0.01). The strongest predictors of drug abuse were: the compound of female gender and travel to Asia (odds ratio (OR), 4.3), education <or=12 school years (OR 3.5), age <or=25 years (OR 2.7), and no malaria prophylaxis (OR 2.6). The brochures failed to decrease the rate of drug abuse (38.9% vs. 34.8% in the control group, p=NS). CONCLUSIONS More than one-third of young Israelis who travel to the tropics use illicit drugs. For many, the trip was their first encounter. Brochures as a sole agent are inadequate, and further means are needed to reduce this alarming trend.

Abstract
The objective of this study was to describe the association between self-reported compliance with last malaria treatment (CMT) and occurrence of malaria during follow-up, controlling for current risk factors. We conducted a prospective open cohort study in Leonislândia, a rural area of Peixoto de Azevedo City, in the Amazon region of Mato Grosso, Brazil. A total of 414 individuals were interviewed at baseline regarding CMT and followed-up for either 8 or 4 months to assess malaria incidence. The associations between CMT and occurrence of malaria were examined through multiple linear regression (when the outcome was malaria episode frequency) or Cox regression (when the outcome was time to malaria onset). Poor CMT (prior to baseline) was identified as an important predictor of the occurrence of subsequent malaria episodes during follow-up among individuals with an indication of being less immune - those whose first malaria episode was relatively recent or those who had an increased number of malaria episodes during the last 2 years. Moreover, surprisingly, it seems that for individuals who are probably more immune (individuals who had experienced their first malaria episode more than 4.5 years previously or those with few or no malaria episodes during the last 2 years), CMT was found to be a poor predictor of increased risk of subsequent malaria. These findings provide compelling evidence for the need to further study CMT and its effect on malaria outcomes.

Abstract
AIMS To identify changes in the presenting number and species of imported malaria in children in southwest London. METHODS A prospective single observer study over 25 years (1975-99) of all cases of paediatric malaria seen at St George's Hospital. RESULTS A confirmed diagnosis was made in 249 children (56% boys; 44% girls; median age 8.0 years). Of these, 53% were UK residents and 44% were children travelling to the UK. A significant increase was noted in the number of cases over the 25 years (1975-79: mean 4.8 cases/year; 1990-99: mean 13.7 cases/year). Over the 25 years Plasmodium falciparum was seen in 77%, P vivax in 14%, P ovale in 6%, and P malariae in 3% of cases. P falciparum had increased in frequency (1975-79: P falciparum 50%, P vivax 50%; 1990-99: P falciparum 82%, P vivax 6%), associated with an increase in the proportion of children acquiring their infection in sub-Saharan Africa. Median time between arrival in the UK to the onset of fever was: P falciparum, 5 days; P ovale, 25 days; P malariae, 37 days; and P vivax, 62 days. Median time interval between the onset of fever to commencement of treatment was 4 days. This had not improved over the 25 year period. Only 41% of UK resident children presenting to hospital had taken prophylaxis and the overall number of symptomatic children taking no prophylaxis was increasing. CONCLUSION Imported childhood P falciparum malaria is increasing in southwest London associated with increasing travel from sub-Saharan Africa. Over the 25 year period there has been no improvement in chemoprophylaxis rates or time to diagnosis.

Abstract
This paper reviews the issues relating to compliance and participation among the men and women of three countries within the remit of the African Programme for the Control of Onchocerciasis (APOC): Cameroon, Nigeria and Tanzania. Project-monitoring data from 109 focus-group discussions, 6069 household-survey respondents and 89 interviews with ivermectin distributors were analysed to gain an insight into the attitudes and behaviours of men and women in relation to ivermectin treatment and their participation in the programme. Although there are no statistically significant gender differences in coverages for ivermectin treatment, culturally prescribed gender relationships influence the ways in which men and women express and experience treatment-related behaviours. Gender roles also affect participation in the programme. Decision-making in communities on the selection of distributors tends to follow socio-cultural hierarchies based upon patriarchy and gerontocracy. Relatively few ivermectin distributors (21%) are women. Although they receive less support than their male counterparts, the female distributors are just as willing to continue ivermectin distribution in the community, and they perform as well or better than men in this regard. The terms 'community-directed', 'community participation' and even 'compliance' obfuscate important gender differences that are inherent in the implementation of onchocerciasis control. Development of strategies that recognize these gender differences will have important implications for long-term adherence to treatment and for the overall quality and sustainability of the programme.

Abstract
The incidence and prevalence of tuberculosis are far more common among third world populations immigrating to the United States than among US-born citizens. Immigrants' failure to comply with an anti-tuberculosis treatment can impede completion of care and further confound this public health problem. Barriers to patient--provider communication can negatively influence adherence to a medical regimen. Patients who are unable to comprehend medical advice and do not see it as personally salient are less likely to follow their provider's medical advice. In this paper, the authors focus on efforts to develop a patient education tool targeting Spanish-speaking Latino immigrant patients to facilitate communication with tuberculosis clinicians. A description of the multi-stage developmental processes is presented including conducting a needs assessment, development of visual and written messages, review/critique by tuberculosis experts, field-testing, revisions, and distribution. Formative evaluation and field testing indicates promise for improving communication using this tool.

Abstract
BACKGROUND Travel associated malaria is a major health risk for visitors to malaria endemic destinations. To examine the knowledge of malaria prevention, risk perception, current prophylactic behavior, and compliance with chemoprophylaxis and personal and environmental protection measures we conducted a study in a cohort of travelers exiting Zimbabwe from two international airports during a peak malaria transmission period. METHODS Data were collected by pretested self-administered questionnaires from 595 adults in the departure lounges of Harare and Victoria Falls International airports. Excluded were children and travelers from the African continent. A multilingual research assistant supervised data collection. RESULTS The majority of travelers obtained health advice prior to travel. Patterns of protective behavior and compliance with prophylaxis were inconsistent with a high perception of malaria threat and good knowledge. About 23% of travelers failed to use chemoprophylaxis during their visit. In the group of travelers who used chemoprophylaxis, 18% were noncompliant. Fifteen drug combinations were in use. Full compliance with medication plus use of personal preventive measures always was estimated as 13%. Forgetfulness was the main cause of noncompliance, followed by deliberate omission due to side effects. Of 57 travelers who reported side effects from current medication, over half used mefloquine. CONCLUSIONS There is a need to examine how people process personal risk and communications about risk. We must recognize the competition between precautionary measures against malaria and other life demands that are imposed by travel, especially in young long stay travelers and persons visiting primarily for business purposes. Mediating a protective response will also depend on judgments about the effectiveness of the action, strengthening travelers intentions toward adherence, and increasing efficacy perception by individuals and their peers. Conflicts in prophylactic recommendations need to be resolved. As ecotourism develops in Zimbabwe and other malaria regions, stakeholders in this rapidly growing industry must be made aware of the important role they can play in protecting clients from malaria.
