How much behaviour change should we expect from health promotion campaigns targeting cognitions? An approach to pre-intervention assessment

For those planning interventions based on social cognition models, it is usually not clear what impact on behaviour will follow from attempts to change the cognitions specified in these models. We describe a statistical simulation technique to assess the likely impact of health promotion targeting Theory of Reasoned Action (TRA)-based predictors of condom use. We apply regression-based simulation techniques to data from the SHARE project (n?=?756 Scottish adolescents) to assess the potential impact of changes in cognitions on condom use. Results support the predictive utility of TRA-based models of psychological antecedents of condom use but also provide a cautionary warning about the magnitude of behaviour change likely to be achieved by interventions based on such models.     

Perceptions of the roles of behaviour and genetics in disease risk: Are they associated with behaviour change attempts

Objective: We examined selected survivor characteristics to determine what factors might moderate the response to two psychosocial interventions.

Design: Seventy-one prostate cancer survivors (PCSs) were randomly assigned to either a telephone-delivered health education (THE) intervention or a telephone-delivered interpersonal counselling (TIP-C) intervention.

Measures: Psychological quality of life (QOL) outcomes included depression, negative and positive affect, and perceived stress.

Results: For three of the psychological outcomes (depression, negative affect and stress), there were distinct advantages from participating in THE. For example, more favourable depression outcomes occurred when men were older, had lower prostate specific functioning, were in active chemotherapy, had lower social support from friends and lower cancer knowledge. Participating in the TIP-C provided a more favourable outcome for positive affect when men had higher education, prostate specific functioning, social support from friends and cancer knowledge.

Conclusion: Unique survivor characteristics must be considered when recommending interventions that might improve psychological QOL in PCSs. Future research must examine who benefits most and from what components of psychosocial interventions to enable clinicians to recommend appropriate psychosocial care.     

Developmental and Gender Differences in Future-Oriented Decision-Making During the Preschool Period

A child version of the Iowa Gambling task was used to explore the developmental and gender differences in decision making of 4-year-olds (N?=?141). The task required children to choose between two decks: a deck with higher immediate rewards and a deck with higher future rewards. Developmental differences between young (4.0–4.5) and older (4.6–4.11) children were found, with older 4-year-olds choosing more from the deck with higher future rewards. Gender differences were found for decision-making strategy. It is suggested that these differences in approaches might account for the pattern of gender differences found in past research.     

Sailing for New Atlantis

Several academic traditions have addressed epistemological objectivity and/or partisanship in the study of technoscientific controversies. On the one hand, positivist and relativist scholars agree that the political commitments of the social researcher should not impinge on scientific enquiry, while on the other hand, feminist and Marxist scholars not only take stands in diverse technoscientific debates, but even claim their agendas to be more credible than those of orthodox scientists. Such perspectives stress that all research is partisan in one way or another because it involves questions of who controls, manipulates, and establishes decisions, facts, and knowledge. With this in mind, it is possible to identify different forms of partisan research including capture by participants, de facto and overt partisanship, and mercenary scholarship. These different forms of partisan scholarship are characterised by differences in the motives underlying epistemological choices of research topic and method, personal commitments to the fields studied, use of research findings in controversies, and positioning of results in wider debates. Two examples help to illustrate partisan scholarship: first, a study of new technologies for managing climate change (carbon dioxide capture and storage); and second, the construction of the new underground metro system in Athens and its accommodation of accessibility standards. Both cases entail partisan positions and raise similar concerns about the orthodox epistemological assumptions underpinning sociotechnical systems, especially when it comes to technoscientific controversies. Supporting STS partisan scholarship, therefore, enables greater social and democratic engagement with technoscientific development.     

Impact and Causes of Rater Severity/Leniency in Appraisals without Postevaluation Communication Between Raters and Ratees

In performance appraisals, some assessors are substantially more lenient than others. Research on this effect in appraisals involving communication and interaction between raters and ratees after the performance evaluation has taken place indicates that it may be at least partly caused by individual differences in assessor personality. However, little is known about the impact or causes of rater severity versus leniency in situations in which there is little or no contact between raters and ratees after the performance evaluation. In Study 1 (N = 174) the strength of the severity–leniency effect in this ‘no‐contact’ context is estimated and found to be similar to that reported for ‘with‐contact’ appraisals. No evidence of an association between assessor personality and assessor severity (vs. leniency) is found in the ‘no‐contact’ context. In Study 2 (N = 54) there is no evidence of an association between the fluid cognitive ability of assessors and the severity of their ratings in a no‐contact context. It is concluded that the severity versus leniency effect probably has a considerable impact on performance ratings in ‘no‐contact’ appraisal settings, but that neither rater personality nor rater cognitive ability appear to play a significant role in this.     

The insistence of vision: Why do people look at a salient stimulus when it signals target absence?

Researchers and practitioners across many fields would benefit from the ability to predict human search time in complex visual displays. However, a missing element in our ability to predict search time is our ability to quantify the exogenous attraction of visual objects in terms of their impact on search time. The current work represents an initial step in this direction. We present two experiments using a quadrant search task to investigate how exogenous and endogenous factors influence human visual search. In Experiment 1, we measure the oculomotor capture—or the tendency of a stimulus to elicit a saccade—of a salient quadrant under conditions in which the salient quadrant does not predict target location. Despite the irrelevance of quadrant salience, we find that subjects persist in making saccades towards the salient quadrant at above-chance levels. We then present a Bayesian-based ideal performer model that predicts search time and oculomotor capture when the salient quadrant never contains the search target. Experiment 2 tested the predictions of the ideal performer model and revealed human performance to be in close correspondence with the model. We conclude that, in our speeded search task, the influence of an exogenous attractor on saccades can be quantified in terms of search time costs and, when these costs are considered, both search time and search behaviour reflect a boundedly optimal adaptation to the cost structure of the environment.     

Differential central resource demands of memory scanning and visual search: The role of consistent and varied mapping

In this paper we compare the effect of mapping on the central resource requirements of two search processes. With consistent mapping of items to the role of either target or distractor, search becomes very efficient; with varied mapping (each item serves as both a target and a distractor in the same experiment), search is less efficient. One interpretation of this effect of manipulating the consistency of mapping is that search under varied mapping requires limited capacity central resources but the requirement for these resources is reduced with consistent mapping. We tested this interpretation by varying the consistency of mapping in memory scanning (Experiments 1 and 2) and in visual search (Experiments 3 and 4) as the second of two tasks in the psychological refractory period (PRP) paradigm. Responses were location based, rather than present/absent judgements, and a target was present on every trial. The results indicated that there was less of a requirement for central resources with consistent mapping than with varied mapping in both memory scanning and in visual search; however, the effect of the mapping manipulation on central resource requirements was different for memory scanning than for visual search. Memory scanning was not done in parallel with a resource-demanding stage of a second task under varied mapping, but was done in parallel with this stage under consistent mapping. Part of visual search under both types of mapping was done in parallel with a resource-demanding stage of a second task and part was not; consistent mapping reduced the duration of the stage of processing that could not be carried out in parallel. We conclude that under consistent mapping, switching among items in memory becomes less controlled and therefore has less of a requirement for central resources than under varied mapping. In visual search, however, consistent mapping improves performance by facilitating the comparison of the target item to items in the search array.     

When 2–3% really matters: The (un)importance of religiosity in psychotherapy

Previous research suggests that clients’ religious beliefs are commonly excluded from therapeutic practice. Often, this exclusion is attributed to practitioners’ lack of knowledge or appropriate skills. Such analyses, however, have little regard for the interactional aspects of the therapist/client encounter. Drawing upon work within discursive social psychology, we argue that the exclusion of religious beliefs does not reflect therapists’ lack of knowledge or awareness but can more usefully be seen as the discursive accomplishment of marginalizing clients’ beliefs. Six practising psychotherapists were interviewed about religious beliefs within the therapeutic process. Participants construct religious beliefs as important but relevant only to restricted categories of clients. They rework religious beliefs as compatible with accepted practice, or construct particular groups of clients as incompatible with the process. Training and other requirements are reformulated in terms of spiritual beliefs rather than religious beliefs. These constructions display awareness of religious beliefs while marginalizing their relevance in practice. Inclusion of clients’ religious beliefs to best effect will require more psychotherapy to engage more constructively with religion than it does at present.     

European developments

The British National Health Service is 50 years old. The provision of many services has changed considerably through this time in ways that reflect shifts in organization and philosophy. The provision of psychotherapy has been particularly sensitive to these changes in ways that have made it more widely available but also shaped its content. As the pace of change continues to accelerate, some implications of the most recent shifts in philosophy for clinical practice are considered.     

The impact of religious behaviours on the health and well-being of emerging adults

Emerging adulthood is a life stage in which the frequency of religious behaviours often wanes while the risk of mental illness, substance abuse, and risky sexual behaviour increases. The current study explores the role that religious behaviours might play in mitigating these risks among college-attending emerging adults. Survey data were collected on religious service attendance, prayer and meditation, substance use, sexual activity, and life satisfaction. Results revealed a significant effect for religious service attendance on substance use and sexual behaviour and for the frequency of prayer/meditation on life satisfaction, marijuana use, and sexual intercourse. Group comparisons revealed that emerging adults who participated in religious activities reported lower rates of substance use, less sexual behaviour, and greater satisfaction with life. Limitations and suggestions for future research are discussed.
