The sleeper effect in persuasion: a meta-analytic review

A meta-analysis of the available judgment and memory data on the sleeper effect in persuasion is presented. According to this effect, when people receive a communication associated with a discounting cue, such as a noncredible source, they are less persuaded immediately after exposure than they are later in time. Findings from this meta-analysis indicate that recipients of discounting cues were more persuaded over time when the message arguments and the cue had a strong initial impact. In addition, the increase in persuasion was stronger when recipients of discounting cues had higher ability or motivation to think about the message and received the discounting cue after the message. These results are discussed in light of classic and contemporary models of attitudes and persuasion.     

Validation scheme and procedures to analyze consequential validity

The argument-based validation scheme guides assessment of the consequences of testing. The distinction between semantic inference and political inference allows us to combine the validation of the consequences in a single validation scheme. The validation process should produce evidence about the assumptions that support both types of inference. After presenting the validation scheme, we provide examples of its use in the assessment of the testing of two applications: the use of high-stake tests in educational contexts and the validation of adjustments made in standardized tests for people with disabilities. Finally, we propose procedures for the validation of consequences and we discuss the suitability of the argument-based validation scheme for the validation of the consequences of testing in Spain.     

Nature, decay, and spiraling of the effects of fear-inducing arguments and HIV counseling and testing: a meta-analysis of the short- and long-term outcomes of HIV-prevention interventions.

OBJECTIVE: To examine the long-term efficacy of both fear-inducing arguments and HIV counseling and testing at encouraging and maintaining knowledge about HIV transmission and prevention, as well as condom use. DESIGN: Analyses were conducted with a sample of 150 treatment groups and 34 controls and included measures of change at an immediate follow-up and a delayed follow-up. MAIN OUTCOME MEASURES: The main outcome measures were perceived risk of HIV infection, knowledge about HIV, and condom use. RESULTS: Results indicated that receiving fear-inducing arguments increased perceptions of risk at the immediate follow-up but decreased knowledge and condom use, whereas resolving fear via HIV counseling and testing decreased perceptions of risk and increased knowledge and condom use at both the immediate and delayed follow-ups. The effects on perceived risk [corrected] decreased over time, but the effects on knowledge [corrected] condom use became more pronounced. CONCLUSION: Inducing fear is not an effective way to promote HIV-relevant learning or condom use either immediately following the intervention or later on. However, HIV counseling and testing can provide an outlet for HIV-related anxiety and, subsequently, gains in both knowledge and behavior change immediately and longitudinally.     

Who participates in which health promotion programs? A meta-analysis of motivations underlying enrollment and retention in HIV-prevention interventions

This meta-analysis examines whether exposure to HIV-prevention interventions follows self-validation or risk-reduction motives. The dependent measures used in the study were enrolling in an HIV-prevention program and completing the program. Results indicated that first samples with low prior condom use were less likely to enroll than samples with high prior condom use. Second, samples with high knowledge were less likely to stay in an intervention than were those with low knowledge. Third, samples with medium levels of motivation to use condoms and condom use were more likely to complete an intervention than were those with low or high levels. Importantly, those patterns were sensitive to the interventions' inclusions of information-, motivation-, and behavioral-skills strategies. The influence of characteristics of participants, the intervention, and the recruit procedure are reported.     

Adapting Homework for an Older Adult Client With Cognitive Impairment

There is growing evidence that psychosocial treatments incorporating behavioral intervention strategies can be effective in the treatment of depression in older adults with cognitive impairment. However, less work with such cases has focused on the use of cognitive interventions in tandem with these behavioral intervention strategies. This case study describes how cognitive behavioral intervention strategies and related homework assignments were tailored and integrated to successfully treat depressive symptoms in an older African American diagnosed with probable Alzheimer’s disease. Examples of the homework strategies utilized are introduced by phase of treatment. We also discuss ways to overcome barriers to homework completion as well as methods to incorporate the client’s sociocultural context and personal history into homework.     

Social perception of the Spanish law for young offenders

The implementation of the law 5/2000 for the regulation of Criminal Responsibility for Minors has led to a change in interventions in cases of juvenile offenders. This law promotes the educational and rehabilitative aims of the measures imposed. However, the focus of the media on the most serious cases has generated considerable alarm in society in general. The aim of this study is to determine the social perception of Law 5/2000. For this purpose, a sample of 936 people from the Autonomous Region of the Canary Islands was surveyed. The main results indicate that there is a significant lack of knowledge about the law and that people tend to think that the measures taken are not as effective as studies carried out in connection with this subject have shown. Nevertheless, the people surveyed are more in favour of educational measures than of measures that penalize. These results are discussed in connection with the importance that community factors have in dealing with juvenile delinquency, and in particular, in the power of social pressure to modify legislation, and of the community to assume responsibility for the reinsertion of juvenile offenders.     

Use of multilevel logistic regression to identify the causes of differential item functioning

Given that a key function of tests is to serve as evaluation instruments and for decision making in the fields of psychology and education, the possibility that some of their items may show differential behaviour is a major concern for psychometricians. In recent decades, important progress has been made as regards the efficacy of techniques designed to detect this differential item functioning (DIF). However, the findings are scant when it comes to explaining its causes. The present study addresses this problem from the perspective of multilevel analysis. Starting from a case study in the area of transcultural comparisons, multilevel logistic regression is used: 1) to identify the item characteristics associated with the presence of DIF; 2) to estimate the proportion of variation in the DIF coefficients that is explained by these characteristics; and 3) to evaluate alternative explanations of the DIF by comparing the explanatory power or fit of different sequential models. The comparison of these models confirmed one of the two alternatives (familiarity with the stimulus) and rejected the other (the topic area) as being a cause of differential functioning with respect to the compared groups.     

Mood congruent Bias in Interpretation of Ambiguity Strategic Processes and Temporary Activation

Three experimentsinvestigated the tendency of high-anxiety individuals to interpretambiguous information in a threatening fashion. Priming ambiguous sentences (concerned with ego-threat, physical-threat, or non-threat events) were presented, followed by a disambiguating sentence in which a target word either confirmed or disconfirmed the consequence implied by the priming context. The sentences were presented word-by-word at a predetermined pace. Subjects read the sentences and pronounced the target word (naming task), which appeared either 500 msec or 1,250 msec after the onset of the last word (pre-target word) in the priming context. Results indicated that high-anxiety subjects named target words confirming threats faster than low-anxiety subjects, relative to non-threat words. Furthermore, this interpretative bias is: (a) strategic, rather than automatic, as it occurred with a 1,250-msec SOA, but not with a 500-msec SOA; (b) temporary, as it was found under evaluative stress conditions increasing state anxiety, butnot withnon-stress; and (c) specificto ego-threats, as it happened with ambiguous information concerning self-esteem and social evaluation, rather than with physical-threat-related information.     

Interactions between intrinsic principles of similarity and proximity and extrinsic principle of common region in visual perception

The interactions between intrinsic grouping principles (by proximity or by similarity in shape or luminance) and extrinsic grouping by common region were examined by presenting both principles acting alone or conjoined with another principle in visual patterns. The procedure used in our study closely mirrored that of Quinlan and Wilton (1998 Perception 27 417-430). However, in the present experiment, the intrinsic and extrinsic grouping principles involved had similar relative salience in order to avoid their possible effects on interactions. The results showed that the grouping effect of conjoined cooperating principles was greater than that of either principle acting alone, and the grouping effect of conjoined competing principles was lower than that of either principle operating alone. Compatibility of data with additive effects of grouping principles has been examined.     

The Short Nicotine Dependence Syndrome Scale (NDSS-S) in Spanish smokers

We present a brief scale derived from the Nicotine Dependence Syndrome Scale (NDSS). We used a sample of 1.061 daily smokers, which was obtained from five Primary Care Health Centers, a Unit of Alcoholism, and a Smoking Cessation Unit. All smokers were evaluated with the NDSS and the SCID to assess nicotine dependence according to DSM-IV criteria. The results indicate the existence of a general factor of nicotine dependence according to the NDSS. We selected the items with a higher factor loading (>.50), obtaining a short scale of 6 items. With this brief scale, we obtained results similar to those of the total scale in the diverse variables (sociodemographic and smoking) of the study. Scale reliability is satisfactory (a= .79), the correlation between the short and the total scale is very high (r=.95, p<.001) and the short scale discriminates the smokers in terms of cigarette consumption and nicotine dependence, as assessed with the SCID. The operation under the ROC curve is excellent (area under the curve .84). The data indicate the usefulness of this brief scale (NDSS-S) to assess nicotine dependence in smokers.
