Parent Reports and Laboratory Assessments of Child Temperament: A Comparison of Their Associations With Risk for Depression and Externalizing Disorders

Parent reports and laboratory assessments of child temperament traits were compared in terms of their associations with 2 indices of risk for future maladjustment: maternal history of depression and disruptive school behavior. A community sample of 99 pre-school-aged children completed a standardized battery of laboratory tasks designed to tap positive emotionality (PE) and anger. Parent reports of child temperament were collected, and maternal history of depression was assessed using structured clinical interviews. An average of 18.5 months after the initial laboratory assessment, teacher reports of disruptive school behavior were collected. Structural equation models were used to test the association between the 2 assessment approaches of child temperament and maternal history of depression and disruptive school behavior. Laboratory measures and parent reports of anger were equally good at predicting disruptive school behavior, while laboratory measures of PE showed stronger associations with maternal history of depression than parent report.     

Cultural and ethical issues concerning research on American Indian youth

A study of American Indian youths illustrates competing pressures between research and ethics. A stakeholder-researcher team developed three plans to protect participants. The first allowed participants to skip potentially upsetting interview sections. The second called for participants to skip potentially upsetting interview sections. The second called for participants flagged for abuse or suicidality to receive referrals, emergency 24-hr clinical backup, or both. The third, based on the community's desire to promote service access, included giving participants a list of service resources. Interviewers gave referrals to participants flagged as having mild problems, and reported participants with serious problems to supervisors for clinical backup. Participants seldom chose to skip sections, so data integrity was not compromised. However, participants did have more problems than expected (e.g., 1 in 3 had thought about suicide, 1 in 5 had attempted suicide, and 1 in 4 reported abuse), so service agencies were not equipped to respond. Researchers must accept the competing pressures and find ethically appropriate compromises that will not undermine research integrity.     

Contrast and the justification of effort

When humans are asked to evaluate rewards or outcomes that follow unpleasant (e.g., high-effort) events, they often assign higher value to that reward. This phenomenon has been referred to ascognitive dissonance or justification of effort. There is now evidence that a similar phenomenon can be found in nonhuman animals. When demonstrated in animals, however, it has been attributed to contrast between the unpleasant high effort and the conditioned stimulus for food. In the present experiment, we asked whether an analogous effect could be found in humans under conditions similar to those found in animals. Adult humans were trained to discriminate between shapes that followed a high-effort versus a low-effort response. In test, participants were found to prefer shapes that followed the high-effort response in training. These results suggest the possibility that contrast effects of the sort extensively studied in animals may play a role in cognitive dissonance and other related phenomena in humans.     

Occurrence of imagery and its link with early memories in agoraphobia

Recent cognitive models suggest that mental imagery can help us understand the maintenance of anxiety disorders (e.g., de Silva, 1986; Hackmann, Surawy, & Clark, 1998). However, imagery is relatively unexplored within agoraphobia. Such images are also thought to be useful in uncovering memories that occurred around the onset of a disorder (Hackmann, Clark, & McManus, 2000). A total of 20 patients with agoraphobia and 20 matched controls took part in this investigation. Participants described any recurrent images they experienced in agoraphobic situations, and also any associated memories. All patients with agoraphobia (but no control participants) reported having distinct recurrent images in "agoraphobic situations". Most images involved several sensory modalities and in the majority of cases appeared to be linked with unpleasant memories of events experienced many years previously. While these exploratory findings require replication, potential treatment implications are discussed.     

Person factors associated with suicidal behavior among African American women and men

This study compared person risk factors among the following groups of low-income, African American adults in an urban, public hospital: (a) suicide attempters and nonattempters, (b) male and female attempters, and (c) all 4 groups (50 female attempters, 50 female nonattempters, 50 male attempters, and 50 male nonattempters). Participants completed psychological distress, aggression, substance use, cognitive processes, religiosity/spirituality, and ethnic identity measures. Compared with nonattempters, attempters reported more psychological distress, aggression, substance use, and maladaptive coping strategies; less religiosity/spirituality; and lower levels of ethnic identity. Male attempters endorsed more substance use than female attempters. No person risk factors differentiated among the 4 groups. Assessment of person risk factors and implementation of commensurate culturally competent interventions are recommended.     

The Body Image Quality of Life Inventory: further validation with college men and women

The Body Image Quality of Life Inventory (BIQLI) was recently developed to quantify both the positive and negative effects of body image on one’s psychosocial quality of life. The current study was conducted to further validate the measure with both men and women and to evaluate its psychometric reliability and validity among college students (N=603). Results confirmed that the 19-item measure was an internally consistent and unidimensional measure for both sexes. A significantly more favorable body image quality of life was reported by men than women, by African American than White women, and by women with lower body mass indices. Significant body image correlates included body image evaluation, investment, and situational dysphoria. A better body image quality of life was also related to higher self-esteem, optimism, and social support for both sexes and to less eating disturbance among women. The potential utility of this construct and unique instrument in further research, especially with medical populations, is discussed.     

A survey of psychologists' attitudes towards and utilization of exposure therapy for PTSD

Although research supports the efficacy of exposure therapy for PTSD, some evidence suggests that exposure is under-utilized in general clinical practice. The purpose of this study was to assess licensed psychologists' use of imaginal exposure for PTSD and to investigate perceived barriers to its implementation. A total of 852 psychologists from three states were randomly selected and surveyed. An additional 50 members of a trauma special interest group of a national behavior therapy organization were also surveyed. The main survey results indicate that a large majority of licensed doctoral level psychologists do not report use of exposure therapy to treat patients with PTSD. Although approximately half of the main study sample reported that they were at least somewhat familiar with exposure for PTSD, only a small minority used it to treat PTSD in their clinical practice. Even among psychologists with strong interest and training in behavioral treatment for PTSD, exposure therapy is not completely accepted or widely used. Clinicians also appear to perceive a significant number of barriers to implementing exposure.     

Neural correlates of the effects of morphological family frequency and family size: an MEG study

Schreuder and Baayen (Schreuder. R., & Baayen, R. H. (1997). How complex simplex words can be. Journal of Memory and Language 37, 118-139) report that lexical decision times to nouns are not sensitive to the cumulative frequency of the noun's morphological derivatives in its "morphological family", even though such a cumulative frequency effect is obtained in the domain of inflection. Under a decomposition view of derivational morphology, this constitutes a puzzling exception to the robust finding that lexical frequency is one of the major determinants of behavioral response latencies. If morphologically complex words are decomposed, each occurrence of a member of a noun's morphological family should add to its root-frequency. We investigated the effects of morphological family frequency on the magnetoencephalographic response component M350, which shows sensitivity to factors affecting early stages of lexical processing, including lexical frequency. We hypothesized that high morphological family frequency should have a facilitory effect on the M350, even though no such effect can be seen in response time, presumably due to competition among possible root-affix combinations. Contrary to this hypothesis, we found that high family frequency elicits an M350 inhibition, suggesting that competition among morphological family members occurs at the M350. The result is significant, since there is evidence that competition among phonologically similar words occurs after, not at, the M350. Thus, our results suggest that competition within a morphological family precedes competition within a phonological similarity neighborhood.     

What do you do when things go right? The intrapersonal and interpersonal benefits of sharing positive events

Four studies examined the intrapersonal and interpersonal consequences of seeking out others when good things happen (i.e., capitalization). Two studies showed that communicating personal positive events with others was associated with increased daily positive affect and well-being, above and beyond the impact of the positive event itself and other daily events. Moreover, when others were perceived to respond actively and constructively (and not passively or destructively) to capitalization attempts, the benefits were further enhanced. Two studies found that close relationships in which one's partner typically responds to capitalization attempts enthusiastically were associated with higher relationship well-being (e.g., intimacy, daily marital satisfaction). The results are discussed in terms of the theoretical and empirical importance of understanding how people "cope" with positive events, cultivate positive emotions, and enhance social bonds.
