Social Psychology of Health: Key Readings

The chapter applies Leventhal's Common-Sense Model to asymptomatic hypertension, showing that patients' mental representations—particularly their sense of identity (symptoms they attribute to the condition) and timeline (acute versus chronic expectations)—predict adherence more powerfully than objective severity. This challenges the assumption that patients fail to follow medical advice because they misunderstand biomedical facts. Instead, the model argues patients construct coherent but often inaccurate schemata that make non-adherence feel rational. The hypertension case is paradigmatic: because the condition produces no felt symptoms, patients whose representations lack a symptom identity see no reason to continue medication. This chapter, reprinted from a 1985 article, serves as the volume's anchor for its opening section on mental models, demonstrating the CSM's empirical reach before the model was widely adopted.

The Health Belief Model treats health behavior as a function of perceived susceptibility, severity, benefits, and barriers—essentially a cost-benefit calculation. The papers collected here, particularly those in the mental models and message framing sections, historicize this approach by showing that health decisions are shaped by richer cognitive structures: illness representations, affective responses, and social comparisons. Leventhal's model embeds beliefs within a dynamic self-regulation process, while Rothman and Salovey's framing research shows that whether a message emphasizes gains or losses matters differently for prevention versus detection behaviors. The volume thus positions social psychology as offering more textured, process-oriented explanations than the static variable approach of earlier health-belief frameworks.

Leventhal appears in the volume through a reprinted article (Meyer, Leventhal, and Guttmann on hypertension), not as a co-editor or author of new material. Salovey and Rothman selected that paper to exemplify the 'mental models' approach in their opening section, but their editorial framework is broader—the volume organizes papers into sections on health information processing, social influence, social support, and personality. Leventhal's Common-Sense Model is presented as one influential strand within social psychology's engagement with health, not as the volume's organizing theory. Readers seeking Leventhal's own comprehensive statement of the model should consult his original publications or the later handbook chapters, not this edited reader.

A persistent misconception is that fear-arousing messages—emphasizing the risks of inaction—are generally more persuasive than positive appeals. The papers by Rothman, Salovey, and colleagues collected here, particularly the reprinted 1997 Psychological Bulletin review and the 1999 empirical study, demonstrate that the gain/loss framing effect depends on behavior type. Gain-framed messages (emphasizing benefits of action) work better for prevention behaviors like sunscreen use, while loss-framed messages (emphasizing costs of inaction) work better for detection behaviors like mammography. The volume shows that framing effects are not universal but conditional on how the behavior is mentally represented—whether it maintains health or detects illness. This nuances the common assumption that 'scaring people works.'

The volume's section on social support reprints two seminal papers: House, Landis, and Umberson's 'Social Relationships and Health' and Cohen's 'Psychosocial Models of the Role of Social Support in the Etiology of Physical Disease.' Together they present the evidence that social integration predicts mortality and morbidity, and they theorize mechanisms—buffering versus main effects models. The inclusion of these papers positions social support not as a vague 'psychosocial factor' but as a measurable structural variable with documented physiological pathways. The volume thus connects social psychology's traditional interest in interpersonal processes to health outcomes through specific, testable mechanisms rather than general appeals to 'stress' or 'well-being.'

A recurring limitation, noted in later meta-analyses by Hagger and Orbell, is that the model's process claims—that representations lead to coping which leads to outcomes which feed back into representations—are rarely tested as a sequential process in cross-sectional studies. Most research measures representations and outcomes at a single time point, treating dimensions as independent predictors rather than elements of a dynamic system. The volume's reprinted hypertension chapter exemplifies this limitation: it demonstrates associations but cannot establish the recursive feedback the model describes. Additionally, the model's focus on individual cognition gives less attention to social-structural determinants of health behavior, a gap later extensions have attempted to address.
