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.     

The link between religion and spirituality and psychological adjustment: the mediating role of optimism and social support

Although optimism, social support, religiousness, and spirituality are important predictors of adjustment, rarely have studies examined these variables simultaneously. This study investigated whether optimism and social support mediated the relationship between religiousness and adjustment (distress and life satisfaction) and between spirituality and adjustment. Findings indicate that the relationship between intrinsic religiousness and life satisfaction and between prayer fulfillment and life satisfaction was mediated by optimism and social support. Furthermore, the relationship between religiousness and adjustment varied depending on how religiousness was operationalized and whether positive versus negative adjustment indicators were used. That is, intrinsic religiousness and prayer fulfillment were associated with greater life satisfaction, but extrinsic religiousness was not associated with life satisfaction. These findings were significant even after accounting for covariates (age, gender, ethnicity, social desirability). Results suggest religiousness and spirituality are related but distinct constructs and are associated with adjustment through factors such as social support and optimism.     

The self in action: lessons from delusions of control

Patients with delusions of control are abnormally aware of the sensory consequences of their actions and have difficulty with on-line corrections of movement. As a result they do not feel in control of their movements. At the same time they are strongly aware of the action being intentional. This leads them to believe that their actions are being controlled by an external agent. In contrast, the normal mark of the self in action is that we have very little experience of it. Most of the time we are not aware of the sensory consequences of our actions or of the various subtle corrections that we make during the course of goal-directed actions. We know that we are agents and that we are successfully causing the world to change. But as actors we move through the world like shadows glimpsed only occasional from the corner of an eye.     

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.     

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.     

Altering "motivational" variables alters induction produced by upcoming food-pellet reinforcement

Previous research has demonstrated that rats will increase their rates of lever pressing for sucrose rewards in the first half of an experimental session when food pellets, rather than the same sucrose, continually serve as the reward in the second half of the session. This effect has been coined induction, and the present study investigated whether it could be altered by altering "motivational" variables. Experiment 1 manipulated subjects' motivation by altering, across conditions, their level of food deprivation. Predictably, the size of induction varied directly with level of deprivation. Experiments 2 and 3 manipulated subjects' motivation by feeding them food pellets and sucrose, respectively, prior to their responding in the experimental session. These pre-session feedings decreased the size of the observed induction in both experiments. The results from the present study indicate that the size of induction is correlated with subjects' motivation to respond for the available reinforcers. They are also consistent with the idea that operant processes underlie the effect. The notion that induction might encompass the concept of "anticipation" is also discussed.

Novel figurative phrases and idioms: phrase characteristics over multiple presentations

In a series of three studies, characteristics of novel figurative phrases were compared with those of established idioms. Studies 1 and 2 found that certain correlations were found to be strong and in one direction for familiar idioms and comparably strong but in the opposite direction for novel figurative phrases, with the correlations for less familiar idioms usually falling partway between these extremes. Study 2 also noted that written or auditory presentation had minimal effects on characteristic ratings. In Study 3 the correlations among characteristics stayed relatively constant for familiar idioms after one, three, or six presentations, but for the novel figurative phrases, after multiple presentations the correlations changed in the direction of the established idioms.     

The invalidity of disclaimers about the effects of social feedback on self-esteem

Despite the fact that several theories suggest that people's self-esteem is affected by social approval and disapproval, many individuals steadfastly maintain that how other people regard them has no effect on how they feel about themselves. To examine the validity of these beliefs, two experiments compared the effects of social approval and disapproval on participants who had indicated either that their self-esteem is affected by how other people evaluate them or that their self-esteem is unaffected by interpersonal evaluation. Results of both studies converged to show that approval and disapproval clearly affected the self-esteem of even those individuals who denied that social evaluations affected their feelings about themselves.
