Psychology and its subfield of health psychology suffer from a lack of standardized terminology and a unified theoretical framework for the prediction and explanation of health behaviour. Hence, it is difficult to establish whether a given theory is logically consistent and to compare different theories. Science involves both empirical and conceptual issues. It is asserted that psychology has overemphasized the former and underemphasized the latter. Empirical psychology needs an explicit, shared conceptual system in order to develop its theories. An example of an axiomatic method (Psycho-Logic; see e.g. J. Smedslund.Psychological Inquiry 1991a; 2: 325–338) is applied to show how the Health Belief Model,the Theory of Planned Behaviour and Social Cognitive Theory all conform to the a priori conditions of acting. One implication is that studies of the predictive power of theories stated as definitional truths only assess auxiliary hypotheses, i.e. the extent to which the measuring instruments are reliable and valid. On the other hand, the introduction of logic into health psychology can facilitate genuine empirical studies by helping to avoid so-called ‘pseudoempirical’ work (Smedslund, J. In Smith, Harré & Van Langenhove (Eds.) Rethinking psychology, 1995). Systems such as Psycho-Logic can also enhance conceptual integration by using logic to explicate and demonstrate intuitive relations. Implications for practitioners are discussed briefly.

This is a reply to K. Glanz, J. Maddock, J. O. Prochaska, D. Seedhouse, and H. Stam on the target article entitled: ‘A pragmatic basis for judging models and theories in health psychology: the axiomatic method’. I defend the claim that one should only test hypotheses that are empirical and avoid testing hypotheses that are necessarily true because of conceptual relations and logic. I argue that the axiomatic system Psycho-Logic (PL) should be added to the other methods which form the health psychologist's methodological ‘toolbox’.

One of the important implications of a population health perspective in public health is an increase in the need for transdisciplinary ways of working. The Community Health Research Unit (CHRU) is presented as an example of an environment where psychology and psychologists work with other disciplines to conduct applied research in population health. Research activities were examined to identify how the disciplines collaborate and to provide evidence of successful interdisciplinary and transdisciplinary approaches which incorporate health psychology. The strengths and challenges of multi-, inter-, and transdisciplinary approaches were examined through a poll of CHRU members. Further, members' views about the contributions of psychology to their work were gathered. Issues of working with different disciplines in a transdisciplinary approach are highlighted and future directions are suggested.

Missing from recent critiques of coping measurement are data demonstrating whether concepts used by researchers are understood by study participants. We asked 101 rheumatoid arthritis patients to complete a structured coping checklist and provide descriptions of their coping for each item checked. Trained researchers coded these open-ended descriptions using the original checklist categories. In general, patients' descriptions of their coping matched researcherderived definitions; however, patients were less likely to interpret cognitive and affective coping strategies in the manner intended by researchers. Patients' descriptions often crossed multiple categories, suggesting complex patterns not captured by most data analytic techniques. Whether they assess coping through structured measures or not, researchers must find ways to examine the multiple meanings and combinations of strategies that constitute the coping process. Keywords

The Magical Beliefs About Food and Health scale (MFH) was developed to assess individual differences in the tendency to adopt eating and health instructions that many magazines, health care books and food ideologies regard as valid but which obey universal laws of similarity and contagion. In a study of 216 individuals, the total MFH score showed good internal consistency and it was associated with various validity criteria as hypothesized (e.g. vegetarianism and other ideological commitments to food choice, female gender, increased neuroticism, experiential thinking, positive attitudes towards alternative medicine, low sensation seeking and endorsement of universalism values). Factor analysis yielded two factors: General Magical Beliefs and Animal Products as Food Contaminants. In addition, three other items (the Animal Products as Personality Contaminants scale) cross-loaded on the two factors. The factor structure and test–retest reliability were confirmed with separate samples. The results showed that the total MFH score is a reliable and valid measure of magical food and health beliefs, and that the subscales may prove useful when a multidimensional assessment of magical beliefs is needed.

This study explored the role of racial segregation in cigarette smoking among US blacks. Five hundred and twenty black adults sampled door-to-door in 10 randomly selected, southern California census tracts completed a survey assessing their degree of racial segregation, experiences with racial discrimination, smoking, and income. Results revealed that the prevalence of smoking among highly segregated blacks (32.9 percent) was significantly higher than that of their less segregated cohorts (19.9 percent). Income, gender, and experiences with racial discrimination did not play a role in smoking but low education levels contributed. Early childhood segregation appeared to be the specific segregation variable associated with smoking among black adults.

This study focuses on the associations of both positive and problematic aspects of social support with depression in patients with rheumatoid arthritis. In a hierarchical multiple regression analysis we found that stressors such as functional limitations and pain are strongly related to depression. Positive and problematic support each explain an additional significant portion of the variance in depression. More positive support is associated with fewer feelings of depression and more problematic support is associated with more feelings of depression. An interaction effect between positive and problematic social support indicates that the negative aspects of problematic support may be partly diminished by positive support (buffering effect). Patients receiving more problematic support and less positive support experience the most feelings of depression.

This study compared the effects of 20 minutes of treadmill exercise at a prescribed intensity exercise (65% VO₂max) and a preferred intensity exercise on psychological affect and exercise enjoyment in aerobically fit individuals. Affect was measured before exercise, at 5-minute intervals during exercise and 5 minutes post-exercise. Heart rate, ratings of perceived exertion (RPE) and enjoyment were also measured during each session. Results indicated that there was no difference in psychological affect or enjoyment between the two exercise sessions, although work rate was higher in the preferred condition. However, pre-exercise values of affect played an influential role in the affective response to exercise. These results suggest that allowing fit individuals to select their own exercise intensity may be more beneficial physiologically and psychologically.

The majority of studies on the effects of a diagnosis of learning disability in the family have employed traditional ‘loss’ and ‘stress reaction’ paradigms. In contrast to this approach, the current analysis employed a form of discourse analysis to explore the ways in which parents represented the ‘problem’ during the process of assessment of their child for an autistic spectrum disorder. The analysis suggested that parents employed three main discourses in their talk about the ‘problem’, which were termed the discourse of normal development, the medical discourse and the discourse of disability. The ways in which these discourses were used in constructing the ‘problem’, their relationship to each other and the discursive work underlying the diagnosis are discussed. Although this study focused on the specific case of autism, it is suggested that the findings could inform thinking around the complex ways in which medical diagnosis is constructed by families and extend our understanding of this important aspect of health care practice.
