Abstract
The SARS outbreak served to test both local and international outbreak management and risk communication practices.
The study compares SARS knowledge, perceptions, behaviors, and information between Finns and the Dutch during the SARS outbreak in 2003.
The participants of the study, who used a modified SARS Psychosocial Research Consortium survey, were drawn from Internet panels in Finland (
Adjusted for age, education, and income, Finns were more likely to be knowledgeable and worried about SARS as well as to have low perceived comparative SARS risk and poor personal efficacy beliefs about preventing SARS. Finns were also more likely than the Dutch to have high confidence in physicians on SARS issues but less likely to have received information from the Internet and have confidence in Internet information.
The study shed light on how two European populations differed substantially regarding lay responses to SARS. Understanding these differences is needed in formulating and executing communication and outbreak management.

Although the outbreak was contained relatively quickly, SARS spread from China and other regions in Asia, reaching 29 countries altogether and causing over 8,400 cases of infection resulting in more than 900 deaths [<xref ref-type="bibr" rid="CR1">1</xref>]. The Netherlands, with a population of 16.2 million, neither reported nor confirmed probable cases of SARS. In Finland, with 5.3 million, two people were initially treated as probable SARS cases, but neither was finally classified as such according to the WHO criteria [<xref ref-type="bibr" rid="CR1">1</xref>, <xref ref-type="bibr" rid="CR2">2</xref>]. These two candidates for probable SARS cases, and especially the death from SARS of a Finnish citizen in Asia, attracted intense media attention in Finland.</p><p>Effective infectious disease management and preparedness require international cooperation. At the same time, it is also important to understand local realities such as lay perceptions, immediate reactions and planned behaviors, as well as cultural ways of communication, and people’s trust in the information and its sources.</p><p>No comparative European population data on lay perceptions and reactions to these new epidemics have been published so far, although [<xref ref-type="bibr" rid="CR3">3</xref>] have summarized studies on the public’s response and precautionary actions related to the SARS outbreak both in Canada and the USA. In addition, a small-scale study comparing Chinese and Canadian students stated that both groups overestimated their chances of getting SARS compared to the actual infection rates in Beijing and Toronto. The Chinese, however, were less pessimistic and expressed a stronger optimistic bias—belief in being personally less at risk than others in general [<xref ref-type="bibr" rid="CR4">4</xref>]—than Canadians [<xref ref-type="bibr" rid="CR5">5</xref>].</p><p>Reports from the unaffected countries [<xref ref-type="bibr" rid="CR6">6</xref>, <xref ref-type="bibr" rid="CR7">7</xref>] indicate that people were quite well aware of SARS; they were not very worried but had taken some precautionary and diagnostic actions. The Finnish respondents showed relatively great trust in the ability of health officials to control the SARS epidemic [<xref ref-type="bibr" rid="CR7">7</xref>]. Studies from the countries seriously affected by SARS reported higher figures for precautionary actions, but not of worry, whereas reports on risk perceptions have been variable [<xref ref-type="bibr" rid="CR8">8</xref>–<xref ref-type="bibr" rid="CR10">10</xref>]. Lee-Baggley et al. [<xref ref-type="bibr" rid="CR9">9</xref>] noticed that optimistic thinking in response to SARS was related to the avoidance of public places and lots of people but not to adaptive health behaviors such as use of disinfectants and hand washing. On the other hand, those who had a more empathetic response to the SARS threat were more likely to report engagement in effective health behaviors and less likely to report avoidance.</p><p>Unlike the chronic lifestyle diseases, there are very few studies on illness perceptions of infectious diseases [<xref ref-type="bibr" rid="CR11">11</xref>], including HIV, hepatitis, and influenza [<xref ref-type="bibr" rid="CR12">12</xref>, <xref ref-type="bibr" rid="CR13">13</xref>]. As communicable diseases caused by invisible microbes have been major causes of death in history, one might assume that they are perceived as less controllable than chronic life-style related diseases.</p><p>Knowledge, perceptions, and precautionary behaviors among the population are important in the control of epidemics, as has been learned regarding SARS [<xref ref-type="bibr" rid="CR14">14</xref>]. As briefly mentioned above, people tend to perceive their disease risk optimistically, especially regarding familiar risks as under volitional control, being more pessimistic in relation to less-controllable risks [<xref ref-type="bibr" rid="CR15">15</xref>–<xref ref-type="bibr" rid="CR18">18</xref>]. Both cognitive and emotional matters such as worry and fear have an important bearing on coping with health threats [<xref ref-type="bibr" rid="CR19">19</xref>]. Trust in information and disease management is essential in outbreak management [<xref ref-type="bibr" rid="CR20">20</xref>–<xref ref-type="bibr" rid="CR23">23</xref>].</p><p>Lessons learned from the SARS outbreak may help to prepare for future infectious disease threats more adequately, to understand public’s responses to bio-threats and develop adequate communication protocols for future outbreaks.</p></sec><sec id="Sec2"><title>Purpose</title><p>The present study is founded on the premise that, since to be effective, the outbreak management, harm reduction, and risk communication protocols must take into consideration psychological and social aspects of the outbreak or bio-threat incidence, it is important to explore possible differences between countries. The aim of the present study was to compare the SARS knowledge, risk perceptions, precautionary and diagnostic behaviors, as well as the SARS information sources and confidence in them among Finns and the Dutch.</p></sec><sec id="Sec3"><title>Methods</title><sec id="Sec4"><title>Sample</title><p>National samples both in Finland and the Netherlands were drawn from the respective consumer panels using online survey technology.

The Finns also were more likely to have high confidence in physicians on the SARS issues than the Dutch.

They were also more likely to have low perceived comparative SARS risk and poor personal efficacy beliefs. The Finns also were more likely to have high confidence in physicians on SARS issues than the Dutch. On the other hand, the Finns were less likely to have received information from the Internet and to have confidence in the Internet information than the Dutch.</p><p>In the absence of comparative Finnish–Dutch research about the level of health knowledge, only a hypothetical interpretation of the difference found in the SARS knowledge can be advanced. Potentially extremely active media coverage on SARS in Finland provides one explanation. Weekly magazines, tabloids, and national TV channels devoted frequent stories to the issue during the outbreak. The media coverage was largely related to two probable SARS cases in Finland as well as the publicity around the death from SARS of a high-level Finnish official in Asia.</p><p>Surely these “human faces” brought SARS closer to Finns and thus perhaps invoked interest in following SARS-related news more attentively. No Dutch people were lost nor even suspected of having SARS, which probably meant lower profile media coverage. The knowledge level might also be related to significantly higher percentages of Finns than the Dutch reporting having received SARS information from the media except for the Internet and magazines, as well as from health officials. The Finns also trusted the sources more than the Dutch, except for the Internet.</p><p>Earlier studies have suggested that the media is the most useful source of information about SARS, with the Internet being quite seldom used, especially in Asia [<xref ref-type="bibr" rid="CR8">8</xref>, <xref ref-type="bibr" rid="CR10">10</xref>, <xref ref-type="bibr" rid="CR29">29</xref>]. In general, however, about half of the Finnish adults have reported using the web to get information about health and medicine [<xref ref-type="bibr" rid="CR30">30</xref>, <xref ref-type="bibr" rid="CR31">31</xref>]. We know that the Finns trust the health information received from the official sources, both the media and the authorities in general [<xref ref-type="bibr" rid="CR31">31</xref>–<xref ref-type="bibr" rid="CR33">33</xref>]. We have already reported that Finns trusted the potential of health officials to manage a SARS epidemic in the country [<xref ref-type="bibr" rid="CR7">7</xref>].</p><p>Finns rank as the third most active newspaper buyers in the world with 522 copies per thousand sold daily [<xref ref-type="bibr" rid="CR34">34</xref>]. The percentages of the population with access to and using the Internet are at the same high level in Finland and the Netherlands [<xref ref-type="bibr" rid="CR35">35</xref>–<xref ref-type="bibr" rid="CR37">37</xref>]. There were also differences in public communication about the outbreak management between Finland and the Netherlands during the SARS epidemic. In Finland, the communication was centralized so that there was one designated spokesperson, whereas in the Netherlands, various spokespersons were handling the communication on the epidemic (A. Timen, personal communication). The Netherlands has since decided to use the centralized communication policy. Results concerning the Nordic way of communication and risk perception offer an alternative explanation. [<xref ref-type="bibr" rid="CR38">38</xref>] have reported that the media shapes public perception of risk in the Nordic countries by delivering more factual information about events such as accidents abroad than in other countries.</p><p>Finns being somewhat more likely to report higher levels of concern over SARS might be related to the salience of the SARS threat because of the death of a Finn, which was of compelling interest in the media at the time of the survey. National item-level differences in preventive behavior suggest culturally interesting hypotheses. A typical Finnish feature, for instance, is to prompt people actively and daily to increase hand hygiene during epidemics—this was also done during the SARS epidemic—but there might also be cultural differences in coping with disease threats in general.</p><p>The fact that the Finns were more likely to perceive both their comparative SARS risk and personal efficacy in preventing SARS as low or similar to others is not unique to SARS. It has also been found in other health contexts that Finns are more pessimistic in their evaluations than many other Europeans (e.g., [<xref ref-type="bibr" rid="CR39">39</xref>]. There are established cultural differences in SARS-related optimism (e.g., [<xref ref-type="bibr" rid="CR40">40</xref>, <xref ref-type="bibr" rid="CR41">41</xref>, <xref ref-type="bibr" rid="CR5">5</xref>, <xref ref-type="bibr" rid="CR42">42</xref>]. The culture defines illness representations in two ways: (a) providing linguistic labels for differentiating and categorizing the events forming illness cases and ensuring culturally shared views of diseases by creating expectations as well as directing attention; (b) providing personal contacts strengthening the illness schema development and giving social models for acquisition of the specific procedures for threat management [<xref ref-type="bibr" rid="CR24">24</xref>, <xref ref-type="bibr" rid="CR25">25</xref>].</p><p>The Nordic media with its emphasis on external and international affairs may have downplayed the level of the risk perception [<xref ref-type="bibr" rid="CR38">38</xref>]. One wonders whether what was seen was also related to the symbolic and cultural values of risk estimation in general [<xref ref-type="bibr" rid="CR43">43</xref>, <xref ref-type="bibr" rid="CR44">44</xref>], general national, and culture-specific approaches to health, or the way the SARS outbreak management communication was managed in these two countries.</p><p>The panel surveys were carried out in the second half of June 2003; that is, after the peak of the SARS outbreak, during the period when people were already relatively knowledgeable, and had had time to formulate their emotional and perceptional stance to the SARS epidemic and its potential impact in their respective countries. Although the samples were drawn from national poll agency panels, we cannot exclude selection bias. However, we did the analyses adjusted for the background factors of the samples. The difference in education between the samples is in line with the published figures for educational attainments in Finland and the Netherlands [<xref ref-type="bibr" rid="CR35">35</xref>–<xref ref-type="bibr" rid="CR37">37</xref>]. Although the survey instrument was developed rapidly and without piloting in response to the emerging international SARS outbreak, it was based on a well-known illness perception framework [<xref ref-type="bibr" rid="CR25">25</xref>] established to function in different cultures [<xref ref-type="bibr" rid="CR45">45</xref>].</p><p>Our findings point to the need of contextual, culture-sensitive, and multisector analyses as the basis for international outbreak management policies and risk communication. Local knowledge, topics of worry, risk perception, information sources, and trust in them are all important aspects of the preparedness planning for epidemics and pandemics.</p></sec><sec id="Sec11" sec-type="conclusion"><title>Conclusion</title><p>It is interesting from the psychological and behavioral perspective that two nonaffected European countries have such different levels of SARS knowledge, risk perception, and use of and confidence in the information received. There is an urgent need to study further cultural, societal, and epidemic control aspects affecting lay people’s perceptions and behaviors relevant to planning and implementation of national and international outbreak management policies.</p></sec></body><back><ack><title>Acknowledgement</title><p>Thanks to Mette Lindholm Eriksen for technical assistance in finalizing the manuscript.</p></ack><ref-list id="Bib1"><title>References</title><ref id="CR1"><label>1.</label><mixed-citation publication-type="other">World Health Organization.
