Gimeno, Amick, Benavides and Benach [1] raise a number of issues with a paper recently published in Occupational and Environmental Medicine.[2] It is important that researchers cross-examine others’ findings and conclusions, as well as explain and defend their own findings and conclusions, so that debate can proceed that is both informed and useful for policy and practice.
In the original paper, I present findings that suggest the perceived risk from occupational stress varied across countries in the EU. I interpreted the findings as suggesting an element of social construction is present in such perceived risk, and that this element of social construction could have implications for policy, in respect of risk communication, for example.
There are two important things to note about these conclusions.
First, I analysed perceived risk from occupational stress, and not objective risk. These are recognised as two separate entities.[3] Whilst they are arguably intertwined closely in occupational stress and emotional health,[4] these data do not speak to this issue, and I drew no conclusions concerning objective risk. However, perceived risk is an important issue that can have practical implications, as noted.[2]
Second, it is uncontroversial in many areas concerned with risks to health (e.g. nuclear power, food) that risk is partially socially constructed, at this social construction has important practical implications.[5] There is no reason I know of why there should be controversy concerning the practical implications of a socially constructed element to risk from occupational stress.
Gimeno et al. raise four concerns.
1. The first issue is related to sample selection. The data were drawn from the Third European Survey on Working Conditions (ESWC), and then a more homogenous sample selected of people working in the same country as their nationality. Albeit imperfect (as noted by Gimeno et al), this procedure excludes workers who are more likely to have recent extensive experience of different working cultures. As noted in the paper, then, ‘variation within individuals due to multiple influences of work cultures was minimized’. Note I use the term minimized, rather than excluded. Notwithstanding, this procedure provides a more accurate means of assessing socio-cultural influences on perceived risk of occupational stress than was possible just by comparing responses across country of data collection or by comparing people of different nationalities.
Gimeno et al. explain that there is an influx of foreign workers into the EU, and that these workers may be exposed to more hazardous working conditions. Gimeno et al. make the argument that ‘removing workers who may be experiencing the greatest stress and hazardous working conditions from the sample may represent a severe selection bias’. I would agree with Gimeno et al.had the purpose of the paper been to determine objective risk in all areas of the labour market in the countries surveyed. Further, I agree that such workers are an important section of EU labour markets deserving of research in their own right with a view to informed intervention to enhance their working conditions – and such research should include assessment of perceived and objective risk in due course.
However, the purpose of the paper was to determine whether there is a socially constructed element in the perceptions of stress that can be attributed to socio-cultural variables at the national level. Including such workers may well have skewed the data by introducing a level of bias related to the nationality of immigrant workers in a country.
Gimeno note ambiguity with the statement "individuals who were working in a different country as their nationality". As well as re- reading the paper, I have conducted an electronic search of the paper, and cannot find this quote. Therefore I am unsure of the context of the quote, and so cannot be sure of the source of the perceived ambiguity. However, Gimeno et al. do raise issues not covered in the ESWC data concerning assimilation of social constructs and life-course data, all of which are relevant to propagation of cultural values at an individual level [6] and possibly also risk perception. However, by including only those people who list their nationality as being the same as the country they work in, it is a reasonable assumption that they will be familiar with the dominant cultural values of that country (even if they do not subscribe to those values themselves). Other data would be desirable of course, but unfortunately, they are not available.
2. The second concern raised by Gimeno et al concerns the use index of perceived risk of occupational stress. They raise an issue concerned with principal components analysis (PCA) conducted on the whole sample, rather than the sub-set used to compare the EU countries. It seems that the implication of this argument is that a different cluster of symptoms would be uncovered by PCA conducted on the sub-sample. I re-analysed the data, using only those people that worked in the same country as their nationality. PCA indicated the same pattern of relationships between perceived risk of symptoms.
What does this analysis mean though? It seems that a cluster of symptoms – which may be labelled stress – are commonly perceived as co- occurring. This might be because when such symptoms occur, they commonly occur together. This could reflect a physiological process, or heightened cognitive processing of physical sensations during emotional episodes.[7] However, as other analyses in [2] show, the extent to which the risk of experiencing these symptoms is attributed to work has a socially constructed component.
Gimeno et al. do raise the point that important differences might exist between individual health-related outcomes, and that these health- related outcomes might vary between factors such as type of employment, gender etc. First, in [2], I did control for industry, demographic factors, job dissatisfaction and perceived working conditions. In this way, factors that might represent cross-national variations in working practices (such as working hours) and individual level factors (such as job dissatisfaction) could not be said to account for the pattern of findings. Second, the ESWC contains many individual level questions assessed by single item indicators. By looking at health outcomes assessed by single indicators, there is danger that any findings reflect the error of measurement embedded in single item indicators of indeterminate reliability - rather than the true variable of interest. This threat is magnified in analyses involving large samples, where even small differences due to error can be labelled statistically reliable. By producing a scale – with an acceptable reliability coefficient (a=0.73), this possibility is lessened.[2]
Gimeno et al. also bring attention to the nature of the questions in the ESWC that I used to examine cross-national differences. It is important to note that the question I used asked participants to attribute various symptoms to work, not whether those symptoms were currently being experienced. Therefore, the question reflects a perception of the impact of work on symptoms – and not symptoms themselves or any underlying pathology. Therefore, any conclusions drawn from the data cannot reflect anything other than factors influencing the perceived influence of work on various symptoms.
3. The third concern raised by Gimeno et al regards the empirical status of my conclusion that workers in lower ranked countries might be less likely to attribute minor or non-specific psychosomatic symptoms to work when consulting with health practitioners. Whilst Gimeno et al are aware of no data that support such a conclusion, this conclusion – however conditional the language within which it is phrased - cannot be dismissed without further work. There is evidence that indicates emotional displays and discussion of life stress during consultation might cause misdiagnosis.[8] This potential for misdiagnosis arguably warrants further investigation.
4. The fourth concern raised by Gimeno et al. concerns the discussion section, especially in relation to conclusions with respect to the UK. I conclude that the media and socio-cultural factors – specifically cultural attitudes – might influence perceptions of risk from occupational stress. There is an extensive literature relating to these issues in relation to other risks – and some of the more prominent examples were referenced in [2]. There is also discussion elsewhere of socio-cultural factors and the media in influencing perceptions of risk from occupational stress [9] and in politicising stress as a social issue that subsequently influences reporting of stress.[10]
Gimeno et al. suggest that classifying countries according to common characteristics could provide an a priori basis for explaining the pattern of findings. The cultural approach to risk perception [11] provides one such approach. In this framework, countries with an individualist orientation (Ireland and Great Britain in this sample) would be expected to be ranked lower than other countries. This was indeed the case in [2]. However, countries with a more egalitarian orientation, such as the Nordic countries and Germanic countries, would be predicted to be ranked near the top, and countries with more hierarchical work cultures – such as France – would be expected to be ranked lower than the Nordic and Germanic countries. The results clearly do not bear such predictions out (see 12 for a cultural typology of European countries).
Therefore, the ranking of countries may reflect more complex processes than simple categorisation of countries on cultural or other factors. This conclusion is supported by some of the literature cited in [2] that has been used to discuss the British case [9,13-15]. In this literature, a number of suggestions have been made, in which, factors such as the media, socio-cultural factors and cognitive processes in the perception of risk have been advocated as explanations or partial explanations for perceived risk from occupational stress. I do not know the extent to which the scientific and policy literature in other countries covers such issues, but the fact there is open debate in the scientific community concerning such issues in Britain makes Britain a useful focus for analysis. Moreover, the British case with respect to monitoring stress and intervention is now more interesting, given the introduction of Stress Management Standards by the UK Health and Safety Executive. In due course, the British case will provide a useful focus for analysis of how advisory rather than coercive processes influence reporting and perception of occupational stress. It was for these reasons that the discussion section had some focus on the British case.
So rather than further cross-national comparisons on perceptions of stress – now we know they exist but not why - researchers might find it useful to examine individual countries on a case-by-case basis, so as to build rich pictures of the factors that influence perceived risk from stress in any one societal context and explain in more detail the pattern of findings in [2]. Once such exploratory work has been completed, research can move to hypothesis testing.
Finally, Gimeno et al. note that different rankings are apparent if different dependent variables are used. This should not be surprising – I can think of no reason why sickness absence has to necessarily mirror findings with attributions of stress-related symptoms to work – although there might be several reasons why they could be loosely coupled. Stress is not the only reason for absence from work.
Whether the ranking in [2] is more or less accurate and the reasons for the rankings, only further research can tell. However, the socially constructed elements of stress have real policy implications. They are worthy of further debate and research. To ignore them or deny them ultimately will be to the detriment of policy, intervention and occupational health.

A recent article by Daniels [1] in this journal presented occupational stress data from the 15 European Union (EU) countries.
Cross- national comparisons contribute to our scientific understanding of how and why health-related indicators (i.e. stress) are unequally distributed across countries and provide clues and guidelines for researchers, policy makers and trade unions at the EU level. However, we are concerned the data’s strengths and limitations are not explained appropriately to inform the policy debate. Specifically we have four concerns.
Our first concern is related to sample selection. The data were drawn from the Third European Survey on Working Conditions (ESWC) conducted in 2000.[2] The sampling strategy was designed to obtain nationally representative samples of the total active population, including non- Europeans if they could be interviewed in the national language of the country where they worked. Daniels asserted occupational stress is socially constructed and thus used nationality to obtain a more homogeneous sample. However, removing workers who may be experiencing the greatest stress and hazardous working conditions from the sample may represent a severe selection bias.[3]
The inflow of foreign workers (especially the so called low-skilled immigrants) to the EU advanced industrial countries is increasing.[4] Immigrant workers are becoming a significant part of the active EU population and are likely to rise sharply with the addition of the ten new EU countries.[5,6] Compared to native workers, non-EU nationals have greater problems obtaining jobs.[7] They may obtain employment in contractual jobs where exposure to work-related stressors is high.[8] It is plausible foreign workers are more frequently employed in ‘bad’ jobs exposed to more hazardous work environments.[9]
Furthermore, because of the ambiguity of the statement "individuals who were working in a different country as their nationality" (i.e. immigrants) – it is unclear who is being excluded and whether the issue of the social construction of stress can be redressed through the exclusion. The ESWC does not identify whether a person was born in the country of present nationality, lived in the same country since birth with or without the nationality of that country, or lived, or was born, elsewhere before coming to the country of present nationality. Neither does the ESWC provide data on when, in a life course perspective, the arrival of a person to a country occurred which may be relevant for assimilating social constructs by an individual. All these factors can influence health variability and without such detailed data deductions based only on a person’s nationality seems uncertain.
Second, information bias can affect the results.[3] By means of principal component analyses, Daniels grouped a number of items (stress, anxiety, irritability, sleeping problems, stomach ache, headache, or overall fatigue) to create an "index of perceived risk from occupational stress". However, two methodological issues have to be considered. First, if, as Daniels argues, stress is socially constructed and thereby biased by nationality, how can be the occupational stress index be created using the total sample instead of only those workers who were working in the same country as their nationality. We would agree this was the appropriate approach if Daniels would not have argued for a social construction of stress. Second, in the ESWC questionnaire, a filter question existed before the selection of the symptoms that the author did not mention. Only after replying that their work affected their health, which some 60% of the workers did, could participants endorse any of 22 symptoms.[2] In analyses using the same data set,[8,10,11] we found differences in various health-related outcomes (stress, overall fatigue, job dissatisfaction and sickness absence) by country, type of employment, and gender.[12] So, grouping items without exploring individual symptom variation might hide important differences.
Third, in the discussion section, Daniels stated that according to his findings, compared to workers in higher ranked countries, British workers and workers in other lower ranked countries may be less likely to attribute minor or non-specific psychosomatic symptoms to work (or might attribute them erroneously to other life domains) when consulting with health practitioners. We are aware of no data to support such an assertion. Hence, the findings do not support this conclusion, so we suggest prudence in the application of these results to policy and practice decisions.
Fourth, Daniels ranked the EU countries investigated according to the number of stress related symptoms attributed to work. From these differences Daniels’s made inferences about how sociocultural factors and the role of the media can affect health perceptions. Given the concerns expressed above abut selection and information bias we wonder how the results led to these inferences. Furthermore, although Daniels recognised that these processes may not apply to other EU countries, he focused almost the entire discussion section on the UK, building an idiosyncratic and ad hoc explanation for the UK that seems unsupported by the research. A way to facilitate more systematic analyses could be by classifying the countries according to certain common characteristics. In social and policy research, different typologies have been proposed. For instance, Esping-Andersen’s typology has proven to be useful in comparing welfare states and may be helpful in the present study’s context.[13]
Moreover, the Daniels’ ranking is very different, and in some cases completely inverse, than the one obtained by us when analyzing sickness absence data from the same survey.[14] Among other factors that could explain this divergence, it has to be considered that different outcomes could present different between-countries distributions. Compared to Daniels’ occupational stress index, sickness absence is recognised as a public health surveillance measure indicating countries economic performance.[15] Rankings are an important tool scientists can use to communicate with policy makers. The ESWC provides a unique data source for scientists. Differences between our work and Daniels illustrates the need to develop mechanisms to enable researchers using the ESWC to share results prior to publication.
Finally, we do understand that the space available for short papers limits the author’s possibility to explain in detail all relevant issues. However, we think that authors should give the reader as much information as needed to judge the results validity.
