The Tourette's Disorder Scale (TODS): development, reliability, and validity

To address the lack of a simple and standardized instrument to assess overall illness severity of Tourette's disorder (TD), the authors developed and tested a 15-item scale to measure a broad range of common symptoms including tics, inattention, hyperactivity, obsessions, compulsions, aggression, and emotional symptoms. Independent investigators used the 15-item Tourette's Disorder Scale (TODS) to assess 60 TD patients who were taking part in a double-blind placebo-controlled multicenter 8-week treatment study. Interrater reliability, internal consistency, convergent and discriminant validity, and sensitivity to change were examined. The TODS was associated with good interrater reliability, excellent internal consistency, and favorable levels of validity and sensitivity to change. Individual TODS items showed good convergent and discriminant validity against other measures. The TODS is a simple, efficient way for clinicians and parents to rate the severity of multiple symptoms commonly found in patients with Tourette's disorder.     

Ambivalence About Interpersonal Problems and Traits Predicts Cross‐Situational Variability of Social Behavior

Multiple theoretical perspectives suggest that maladjusted personality is characterized by not only distress, but also opposing or “ambivalent” self‐perceptions and behavioral lability across social interactions. However, the degree to which ambivalence about oneself predicts cross‐situational variability in social behavior has not been examined empirically. Using the interpersonal circumplex (IPC) as a nomological framework, the present study investigated the extent to which endorsing opposing or “ambivalent” tendencies on IPC measures predicted variability in social behavior across a range of hypothetical interpersonal scenarios (Part 1; N = 288) and naturalistic social interactions (Part 2; N = 192). Ambivalent responding for interpersonal problems and traits was associated with measures of distress, maladaptive interpersonal tendencies, and greater variability of social behavior across both hypothetical and daily social interactions, though more consistently for interpersonal problems. More conservative tests suggested that ambivalence predicted some indexes of behavioral variability even when accounting for mean levels and squared means of social behaviors, vector length, gender, and depressive symptoms. Results suggest that processes theorized as typifying personality disorder may apply more broadly to personality maladjustment occurring outside of clinical samples.     

The Pique Technique: Overcoming Mindlessness or Shifting Heuristics?

An unusual request can increase compliance in situations in which the typical response to the request is refusal. This procedure, called the pique technique, is said to be effective because the unusual request causes people to give mindful consideration to it. We tested this explanation in 2 studies. Passersby were asked for either a common amount of change or 37 cents. Participants who inquired about the unusual amount were given either a specific or an uninformative reason. The pique technique increased compliance, but only when participants stopped to ask about the request. These participants gave more money, regardless of the reason provided. The findings failed to support the notion that an unusual request leads to a mindful consideration of it.     

The relationship of social support to depressive symptoms during the transition to high school

The transition to high school is studied as a time when students may experience disruptions in their social support systems. Peer support, family support, and school belonging were hypothesized to be associated with adolescent adjustment, specifically depressive symptoms. Participants included 104 eighth graders and 101 ninth graders from a middle- to high-income, predominantly white community in southern Rhode Island. In year 2, 60 of the original 8th graders were surveyed as 9th graders. Three hypotheses were examined: Social support declines from 8th to 9th grade; depressive symptoms increase from 8th to 9th grade; and social support is significantly associated with depressive symptoms. The hypotheses were tested using cross-sectional and longitudinal analyses. Results indicated that 9th graders experienced more depressive symptoms and lower levels of school belonging as compared to the 8th graders. Changes in parent support and peer support were significantly associated with depressive symptoms in the transition to high school. Implications for increasing school belonging in the 9th grade are discussed.     

The cocktail party effect in infants

Most speech research with infants occurs in quiet laboratory rooms with no outside distractions. However, in the real world, speech directed to infants often occurs in the presence of other competing acoustic signals. To learn language, infants need to attend to their caregiver’s speech even under less than ideal listening conditions. We examined 7.5-month-old infants’ abilities to selectively attend to a female talker’s voice when a male voice was talking simultaneously. In three experiments, infants heard a target voice repeating isolated words while a distractor voice spoke fluently at one of three different intensities. Subsequently, infants heard passages produced by the target voice containing either the familiar words or novel words. Infants listened longer to the familiar words when the target voice was 10 dB or 5 dB more intense than the distractor, but not when the two voices were equally intense. In a fourth experiment, the assignment of words and passages to the familiarization and testing phases was reversed so that the passages and distractors were presented simultaneously during familiarization, and the infants were tested on the familiar and unfamiliar isolated words. During familiarization, the passages were 10 dB more intense than the distractors. The results suggest that this may be at the limits of what infants at this age can do in separating two different streams of speech. In conclusion, infants have some capacity to extract information from speech even in the face of a competing acoustic voice.     

A population-based study of the association between pathological gambling and attempted suicide

The association between pathological gambling and attempted suicide was examined using data from a prevalence study conducted in Edmonton, Alberta, Canada. The sample size was 7,214, the questionnaire was the Diagnostic Interview Schedule, and diagnoses were made on a lifetime basis according to DSM-III criteria. Logistic regression analysis was performed, with attempted suicide as the dependent variable. The odds ratio for pathological gambling was statistically significant (odds ratio = 4.91; 95% confidence interval = [1.41,17.1]) when major depression was the only comorbid mental disorder in the model. As terms for additional mental disorders were included, pathological gambling ceased to be statistically significant. It was concluded that a history of pathological gambling is associated with previous attempted suicide, and that the association may be due to a common factor--"mental illness."     

Effect of a means-end contingency on young children's food preferences.

This study showed that a means-end relationship between two snacks exerts a negative influence on preference for the means snack in the contingency. Two snacks ranked of approximately equal medium appeal were individually chosen from an array by each of 86 children (ages 4 years, 4 months to 7 years, 2 months). Children were then assigned to a means-end condition (where one snack was eaten as a means of gaining the other), a temporal order control group (where one snack was presented and eaten before the other), or a mere exposure control group (where the children chose the order in which they ate the two snacks). Post-treatment rankings of the snacks showed that children in the means-end group came to devalue the means snack relative to the reward snack, despite the demonstrably equal prior appeal of the two snacks. Children in the temporal order and mere exposure control groups did not come to prefer the two snacks preferentially. Implications of the finding that adults can affect children's preferences by relatively minor variations in the manner of presentation are discussed.     

Mnemic neglect is not an artifact of expectancy: The moderating role of defensive pessimism

Research supporting the mnemic neglect model finds that people more easily recall positive than negative personality feedback, even when only asked to imagine that the feedback is real. The same bias is not found when people are asked to recall information about other people. Despite evidence that these findings reflect self‐enhancement motives, more research is needed to rule out the possibility that they instead simply reflect expectancies. Results supported the mnemic neglect model, and revealed that expectancies predicted recall only for a subgroup of participants who did not demonstrate the self–other recall bias characteristic of mnemic neglect: defensive pessimists, who are more likely than other people to process social information by comparing it to their expectancies. These findings suggest that mnemic neglect is not an artifact of expectancies, and is not driven by other self‐evaluation motives (such as self‐verification or self‐assessment).

Mapping Gray’s BIS and BAS constructs onto Factor 1 and Factor 2 of Hare’s Psychopathy Checklist – Revised

Reinforcement sensitivity theory (RST; Gray, 1987; Gray & McNaughton, 2000) has proven to be a valuable tool for understanding psychopathy (e.g., Fowles, 1980, 1988; Newman & Malterer, 2009; Poythress et al., 2008). Recent research has linked two RST constructs, the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS), to individuals with primary psychopathy and secondary psychopathy (Lykken, 1995; Newman, MacCoon, Vaughn, & Sadeh, 2005): Primary psychopaths manifest low BIS reactivity and secondary psychopaths manifest high BAS reactivity. In the present study, we examine the relationships between the BIS/BAS constructs and Factors 1 and 2 of the Psychopathy Checklist – Revised (PCL-R) in a sample of 472 incarcerated male offenders. Paralleling their relationships with primary and secondary psychopathy, the BIS/BAS constructs were differentially related to the two PCL-R factors. Specifically, the influence of the BIS was found to be more prominent than the influence of the BAS for Factor 1, and the influence of the BAS was more prominent than that of the BIS for Factor 2.     

Effectiveness of school-based prevention and intervention programs for children and adolescents with emotional disturbance: A meta-analysis

The present study evaluated the effectiveness of school-based prevention and intervention programs for children and adolescents at-risk for and with emotional disturbance. Published outcome studies (k = 29) from December, 1988, to March, 2006, including 1405 children and adolescents were reviewed. Each investigation was coded on several variables describing the child, parent, and teacher samples, as well as reported outcome results. The overall mean weighted effect size was 1.00 at post-test and 1.35 at follow-up. Mean weighted ESs were 0.42 for between-subjects design studies, 0.87 for within-subjects design studies, and 1.87 for single-subject design studies. Prevention programs yielded a mean weighted ES of 0.54 and intervention programs produced a mean weighted ES of 1.35. Findings for specific outcome foci are presented and implications are discussed.
