Gathering time-series data of behaviors and psychological variables is important to understand, guide, and evaluate behavior-change campaigns and other change processes. However, repeated measurement can affect the phenomena investigated, particularly frequent face-to-face interviews, which are often the only option in developing countries. This article presents three intervention control studies to investigate this issue. Daily diaries in Cuba did not affect behavior or attitudes for persons with intervention but reduced attitudes for persons without intervention. Reactivity of face-to-face interviews in Bolivia was negligible if applied weekly, but strong if applied twice per week. The article concludes with recommendations for gathering time-series data in developing countries.

Compensatory health beliefs (CHBs)–beliefs that an unhealthy behavior can be compensated for by a healthy behavior–can be distinguished into trait and state beliefs. Trait CHBs are stable individual differences, whereas state CHBs are activated in a tempting situation–for example, when faced with an attractive snack. The aim of this study was to test whether diet-specific trait or state CHBs are predictive for an unhealthy behavior–namely, high-calorie snack consumption. A scenario was created in which 66 women aged 16 to 50 were faced with a high-calorie snack. Diet-specific trait and state CHBs correlated moderately with each other. Regression analyses revealed that diet-specific trait CHBs with exercise as the compensatory behavior were significantly predictive for high-calorie snack consumption, over and above control variables such as age, whereas state CHBs were only marginally significant. Diet-specific trait and state CHBs with reduced intake (eat less later) as the compensatory behavior were not related to high-calorie snack consumption. Results showed that trait CHBs are relevant for the prediction of high-calorie snack consumption. Future studies might want to further refine the measurement of CHBs, especially state CHBs.

Abstract. Increasing demands on ecosystems, decreasing biodiversity, and climate change are among the most pressing environmental issues of our time. As changing weather conditions are leading to increased vector-borne diseases and heat- and flood-related deaths, it is entering collective consciousness: environmental issues are human health issues. In public health, the field addressing these issues is known as environmental health. This field addresses both the effects people have on their environment as well as the effects of the environment on people. Psychology, as a discipline concerned with explaining, predicting, and changing behavior has much to contribute to these issues because human behavior is key in promoting environmental health. To date, however, an integrative view of environmental health in psychology is lacking, hampering urgently needed progress. In this paper, we review how the environment and human health are intertwined, and that much can be gained through a systemic view of environmental health in psychology. Based on a review of the literature, we suggest that psychologists unite efforts to promote an integrative science and practice of environmental health psychology, and jointly address environmental-health related behavior. The research agenda for this field will include integrating behavior change theory and intervention approaches. Thereby, psychology can potentially make an important contribution to sustained environmental health for generations to come.
