Illness representations and psychological distress in patients undergoing coronary artery bypass graft surgery

Preoperative psychological distress has been shown to predict both postoperative distress and subsequent cardiac morbidity in patients undergoing coronary artery bypass graft (CABG) surgery. This study assessed the associations between illness perceptions and psychological well-being among 56 patients awaiting CABG surgery using the Profile of Mood States (POMS) and the Illness Perception Questionnaire-Revised (IPQ-R). Patient perceptions of their illness as chronic were associated with reduced beliefs in both personal control over illness and efficacy of treatment, and increased perceived consequences of illness in terms of life functioning. In addition, psychological distress regarding illness was significantly correlated with psychological distress in general. Reduced illness coherence was also associated with increased psychological distress. Preoperative psycho-education aimed at helping patients better understand their illness, treatment, and its effects may reduce psychological distress, and perhaps improve future well-being as a result.     

Don't take another bite: how sociocultural norms for appearance affect women's eating behavior

Four studies tested the impact of exposure to thin images on women's eating behavior. In Study 1, women who were exposed to commercials containing thin models ate less in a taste test than women exposed to neutral commercials. The next two studies revealed that the impact of the thin images could be reduced by challenging the sociocultural norms for appearance. In Study 2, including images of relatively heavier women who have been successful in life (an indirect challenge to the norm) attenuated the impact of the thin images on women's eating behavior. Study 3 demonstrated that convincing women that their peers do not endorse the sociocultural norms also reduced the impact of the thin images. In Study 4, we found that exposure to thin images led to activation of an association between heaviness and rejection and that the more this association was activated, the less participants ate.     

Parent and Teacher Ratings of Attention-Deficit/Hyperactivity Disorder in Preschool: The ADHD Rating Scale-IV Preschool Version

Efforts for early identification and intervention for children with AD/HD have necessitated the development of rating scales of behavior for the preschool population. The standardization, reliability, and validity data were presented for the ADHD Rating Scale-IV Preschool Version. Parent and teacher ratings were collected on 902 and 977 children 3 to 5 years of age, respectively. Raw scores for the Inattention, Hyperactivity/Impulsivity and Total scores were converted to T-Scores and percentile ranks. Reliability coefficients ranged from 0.80 to 0.95 indicating good test–retest reliability. Concurrent validity with the Conners Teacher Rating Scales: Revised-Short and Conners Parent Rating Scale: Revised-Short ranged from 0.54 to 0.96. The ADHD-Rating Scale-IV appears to be a reliable, valid and user friendly measure for screening preschoolers with behavior problems. Future research is needed to validate its widespread use as a screening and diagnostic tool.     

Social-identity functions of attraction to organizations

This article examines the self-presentation goals that underlie attraction to organizations. Expanding on Lievens and Highhouse’s (2003) instrumental vs. symbolic classification of corporate attributes, a theory of symbolic attraction is presented that posits social-identity consciousness as a moderator of the relation between symbolic inferences about organizations (e.g., this company is dynamic and innovative) and attraction to those organizations. A measure of social-identity consciousness is developed, and a series of studies confirmed two dimensions, labeled concern for social adjustment and concern for value expression. Preliminary evidence supports the validity of the measure and its role in moderating attraction to symbolic features of well-known firms.     

Movement abnormalities and the progression of prodromal symptomatology in adolescents at risk for psychotic disorders

The link between movement abnormalities and psychotic disorders is presumed to reflect common neural mechanisms that influence both motor functions and vulnerability to psychosis. The prodromal period leading to psychotic disorders represents both a viable point for intervention and a developmental period that, if studied, could shed light on etiology; however, no published studies have examined the temporal progression of this link. A group with high levels of prodromal symptomatology (i.e., adolescents with schizotypal personality disorder [SPD]; n = 42) and both psychiatric controls (with other personality disorders or conduct disorder [OD]; n = 30) and nonpsychiatric controls ([NC]; n = 49) were recruited. Videotapes of structured psychiatric interviews were coded for movement abnormalities by raters blind to participants' diagnostic status, and follow-up assessments were conducted 1 year later. Controlling for psychotropic medications, the authors found that adolescents with SPD exhibited significantly more motor abnormalities in the face and upper body than did OD and NC controls. At baseline, movement abnormalities were positively correlated with the severity of positive, negative, and total prodromal symptoms. Within the SPD group, baseline movement abnormalities predicted symptom severity 1 year later. Movement abnormalities represent an early risk indicator that may be predictive of later symptom severity and potentially of psychosis onset.     

Memory and learning in children with 22q11.2 deletion syndrome: evidence for ventral and dorsal stream disruption?

This study examined memory functioning in children and adolescents with 22q11.2 Deletion Syndrome (DS; velocardiofacial syndrome). An overall verbal better than nonverbal memory pattern was evident on the Test of Memory and Learning (TOMAL), with children with 22q11.2 DS performing significantly below their siblings and children with low average IQ but similar to children with autism on facial memory. Children with 22q11 DS also performed significantly below their siblings on tests of verbal working memory. Children with autism performed significantly poorer than the siblings of children with 22q11.2 DS only on their recall of stories. Delayed recall was significantly poorer in children with 22q11.2 DS and children with autism, compared to sibling controls. Although there were no significant group differences on tests of multiple trial verbal or visual learning, a relative weakness was noted with multiple trial visual learning in children with 22q11.2 DS and their siblings, suggesting that an alternative or interactive factor other than the deletion may account for the relatively better verbal compared to nonverbal memory abilities. Deficits in facial memory in children with both 22q11.2 DS and autism suggest disruptions in ventral temporal pathways such as between fusiform gyrus and parahippocampal/hippocampal regions whereas deficits in verbal working memory in children with 22q11.2 DS implicates dorsolateral prefrontal regions, both intimating aberrant white matter pathways.     

Fast mapping of multiple words: Insights into when “the information provided” does and does not equal “the information perceived”

A candidate process for explaining the rapid vocabulary acquisition during the preschool years is “fast mapping,” children's ability to sketch partial maps of a word's meaning after brief exposure. The present study examines this process for learning multiple words, testing the hypothesis that children's attention to the information critical for quickly mapping multiple words onto their referents depends on the alternatives available when the words are introduced. Fifty-eight 40-month-old children participated in one of two conditions. In both conditions, each trial for novel Word #1 presented a novel object and three familiar ones. The conditions differed in the object choices presented when novel Word #2 was introduced. Although the same information was available to children in both conditions, younger children showed significantly better learning of the new words in the successive condition than in the concurrent condition. Implications of this for age-related differences and for teaching strategies are discussed.     

The Duke Religion Index: A Psychometric Investigation

This study evaluated the psychometric properties of the Duke Religion Index (DRI) in two separate samples (n ₁=628, n ₂=243) of college students enrolled in randomly selected courses. An exploratory factor analysis of the DRI in the first sample supported a one-factor structure. A subsequent confirmatory factor analysis in the second sample confirmed this model. The internal consistency was excellent in both samples. A significant, positive correlation was found between the DRI and a measure of religious beliefs, supporting the convergent validity of the DRI. These findings provide further support for the reliability and construct validity of the DRI.
