Methodological issues in prevention research: An introduction to the special issue

In recent years increased attention has been directed to prevention research as a means of solving the multitude of complex social and health problems which confront individuals and their societies. Abuse of substances, behavioral dysfunctions, violence, emotional disorders, educational failures, unwanted pregnancies and sexually transmitted diseases are but a few examples of these most difficult problems. As our recognition of the need for sound prevention strategies has grown, so has our sophistication in designing prevention research studies to evaluate the effectiveness of these new strategies. And that sophistication has brought new challenges, some of which are capable of stifling progress because of their complexity. This problem is certain to grow in importance as interventions with multiple components are used more frequently to meet the challenges of the complex social and health problems we face. This special issue evolved out of the recognition that prevention researchers are confronted by a myriad of difficult methodological issues which have inhibited progress in this area. The articles in the issue present innovative methodological solutions designed to overcome these problems so the field can move forward.

Cultural Differences in Psychological Distress Between Asian and Caucasian American College Students

The authors examined possible cultural differences in psychological distress between Asian and Caucasion American college students using the Brief Symptom Inventory.     

Characteristics of taste-mediated environmental potentiation in rats

When rats drink a novel flavor in a distinctive environment and are injected with lithium, potentiated aversions are established to the environment as evidenced by the animals' unwillingness to consume a familiar, nonaversive flavor in this environment. Experiment 1 demonstrates that this potentiation is due to the presence of both the distinctive taste and the environmental cues on the conditioning trials, not simply aversive conditioning to each element or to generalization between the two elements. This potentiation phenomenon was shown to be sensitive to the novelty of the potentiating flavor in Experiment 2. Experiment 3 demonstrated that second-order conditioning is difficult to establish using these procedures, although Experiment 4 revealed that postconditioning extinction of the aversive flavor interfered substantially with environmental potentiation. These outcomes are discussed in terms of their implications for adaptive adjustments in feeding behavior as well as for more general conceptions of associative learning.     

Semantic priming effects for stimuli presented to the right and left visual fields

Studies that have addressed the possibility of hemispheric differences in semantic priming effects have yielded contradictory results. This paper reports the findings of two experiments intended to shed greater light on the issue of hemispheric differences in semantic priming. Experiment 1 used a hemiretinal paradigm and examined manual response latency and response accuracy to four types of word pairs; categorically related, syntactically related, unrelated, and pairs containing a nonword member. Experiment 2 examined the effects of unrecognized, disambiguating flank words on verbal responses to a centrally presented homograph. Experiment 1 yielded no significant visual field differences in magnitude of priming effects when response latency served as the dependent measure, although categorical relatedness facilitated response accuracy for left but not right visual field stimuli. In experiment 2, the disambiguating words had a significant effect on meaning interpretation of the homographs that was independent of visual field of presentation. Taken together, the results of these studies are interpreted as indicating that semantic aspects of linguistic input are automatically processed and can influence the content and latency of subsequent responses, whether presented to the left or right visual field.     

Factors of hemifield differences in form discrimination

The influence of some process-limiting variables on hemifield differences for nonsense shapes in a "same-different" classification task was examined. "Different" responses, but not "same," did show systematic effects. Weakly discriminable and unfamiliar shapes which were presented successively yielded a significant left-hemifield advantage, while highly discriminable and more familiar shapes presented simultaneously yielded a nonsignificant right-hemifield advantage. Discriminability, considered independently of the other variables, had effects in opposite directions: low discriminability tended to favor more the right than the left hemifield in each experiment, but the right hemifield more than the left when the comparison was made between experiments. The results are discussed in terms of the spatial-frequency model (Sergent, 1982b, 1983) and the analytic-holistic distinction.     

Shame,Early Abuse,and Course of Depression in a Clinical Sample: A Preliminary Study

This study of 35 depressed patients was designed to replicate findings from a community sample of a relationship between childhood abuse and bodily shame, and bodily shame and chronic or recurrent depression. In addition, we investigated whether characterological and behavioural shame would also be related to early abuse and depression course. The relation between bodily shame and childhood abuse was replicated. When the other types of shame were considered, bodily shame was the most powerful correlate of early abuse, with behavioural shame showing no relationship. However, all three types of shame appeared to be related to chronic or recurrent course of depression.     

Intergroup Perceptions and Attitudes toward Immigrants in a Culturally Plural Society

The research examined perceptions of Chinese immigrants held by New Zealanders of European and Maori descent. The study (N = 318) adopted an intergroup perspective to test a predictive model of attitudes toward immigrants. It was based on a nation‐wide survey with prospective respondents randomly selected from the New Zealand Electoral rolls. Findings revealed that Maori differed from their European counterparts in predictable ways, reporting more relative deprivation and greater perceived threat, and holding more negative outgroup attitudes. Less contact and greater perceived threat predicted more negative attitudes toward immigrants; in addition, when intergroup boundaries were permeable, the link between perceived threat and negative attitudes was stronger in Maori than New Zealand Europeans. While intergroup relations are traditionally analysed in a dual group formation involving a privileged “dominant” ingroup and disadvantaged “minority” immigrant outgroup, the current research suggests the need to advance beyond this dichotomy to a more inclusive approach and to consider the interface between the historical and political milieux in specific national contexts.
