Sluggish cognitive tempo in children and adolescents with higher functioning autism spectrum disorders: Social impairments and internalizing symptoms

Sluggish cognitive tempo (SCT) was introduced in 1980s in the field of attention deficit hyperactivity disorder (ADHD). Studies indicate that symptoms of SCT are separate from symptoms of ADHD and independently associated with multiple domains of functioning in clinical groups and in typical development. We assessed whether similar pattern would apply to higher functioning autism spectrum disorders (ASD). Children with higher functioning ASD (N = 55; 5?15 years) were divided into the ASD+High SCT (n = 17), the ASD+Medium SCT (n = 18) and the ASD+Low SCT (n = 20) groups based on parent‐rated daydreaming and slowness on the Five to Fifteen questionnaire (FTF). The groups were compared on SCT‐related impairments found in previous studies: social skills, academic functioning, psychiatric symptoms, and processing speed. Assessment methods were the FTF, the Development and Well‐Being Assessment, and the Coding subtest of the WISC‐III. The ADHD symptoms were statistically controlled due to the overlap between SCT and ADHD. The ASD+High SCT and ASD+Medium SCT groups were significantly more likely to have the most pronounced social impairments, and the ASD+High SCT group had significantly higher rate of internalizing disorders compared to the ASD+Low SCT group. Our results suggest that children with higher functioning ASD and high or medium levels of SCT symptoms could be at higher risk for psychosocial impairments than children with higher functioning ASD with low levels of SCT symptoms. Co‐occurring ADHD symptoms do not explain the finding. Recognizing SCT symptoms in higher functioning ASD would be important to targeting preventive support.     

Detection of malingering of psychiatric disorder with the personality assessment inventory: an investigation of criminal defendants

To assess the diagnostic accuracy of the Personality Assessment Inventory (PAI; Morey, 1991) Validity scales for the detection of malingered psychiatric disorders, we divided a sample of criminal defendants referred for forensic evaluation by the federal courts into malingering and not malingering groups based on their performance on the Structured Interview of Reported Symptoms (Rogers, Gillis, & Bagby, 1990). Logistic regression analyses (LGAs) revealed that there were no differences between the malingering and not malingering groups with respect to age, race, years of education, history of drug abuse, or number of previous felony convictions. LGA with malingering versus not malingering as the criterion revealed that the PAI Negative Impression Management (NIM) scale but not the Rogers Discriminant Function (RDF; Rogers, Sewell, Morey & Ustad, 1996) nor the Malingering index (MAL; Morey, 1996) significantly differentiated the malingering from the not malingering group. Receiver operating characteristics analyses demonstrated acceptable sensitivity and specificity for the NIM scale but not the RDF scale or the MAL index. We discuss the results in terms of the suggested cutoff scores for the PAI Validity scales in detecting criminal defendants who are attempting to feign psychiatric disorder.     

Does covenant marriage predict latent trajectory groups of newlywed couples?

Covenant marriage is a legally distinct marriage license available in Arizona, Louisiana, and Arkansas in the United States. This study revisited one of the largest longitudinal dyadic studies on covenant versus standard newlywed couples. Using this dataset of 677 different-sex couples, we explored whether being in a covenant marriage could predict how marital satisfaction developed over the first five marital years. We applied the Growth Mixture Modeling (GMM) method to identify groups that differed in their initial marital satisfaction and trajectory. The results revealed three different trajectory groups—one group showing high and stable marital satisfaction, which we named High Stable, and two groups showing declines in marital satisfaction, one being medium and the other one being low in satisfaction at the beginning of the marriage, and we named them Medium Declining and Low Declining respectively. Spouses with lower initial marital satisfaction experienced a faster decline and suffered the highest divorce rate. Actor-Partner Interdependence Model (APIM) analysis revealed that one's group membership was predicted by their partner's membership, suggesting a mutual influence on marital development. Being in a covenant marriage was able to predict husbands' membership as covenant husbands were found to be more likely in the high stable group.     

Effects of trauma and religiosity on self-esteem

Self-esteem is often lower among persons who have experienced trauma, but religiosity may ameliorate these psychological effects. The purpose of this paper was to examine the relationships among religiosity, self-esteem, and childhood exposure to trauma, utilizing data from the National Comorbidity Survey, a large (N = 8,098) nationally representative population survey in the 48 contiguous states of the USA that assessed religious practices, self-esteem, and exposure to trauma. Exposure to trauma in childhood was assessed through self-report of presence or absence of childhood physical abuse, sexual abuse, or neglect. Religiosity was assessed as the sum of responses to 4 self-report items (religious service attendance, use of religion for comfort and guidance, and importance of religion). Self-esteem was assessed on 9 self-report items adapted from the Rosenberg Self-Esteem Scale. Analysis of variance compared scores for persons who reported exposure to childhood abuse and differed in the value they placed on various religious practices on self-esteem. Persons who reported physical abuse, sexual abuse, or neglect in childhood had significantly lower mean self-esteem than those who did not report these events. There was also a main effect for religiosity in a comparison of persons who reported childhood sexual abuse with those who reported none. The High Religiosity group had higher mean self-esteem than the Medium and Low Religiosity groups. There was a significant interaction as those who reported childhood sexual abuse had lower mean self-esteem than peers who reported none in the Low and Medium Religiosity groups. Mean self-esteem for those who reported childhood sexual abuse was comparable to that of those who reported none in the High Religiosity group.     

ACHIEVEMENT MOTIVATION OF WOMEN: EFFECTS OF ACHIEVEMENT AND AFFILIATION AROUSAL

Alternative propositions to female achievement motivation theory were investigated in this study. The subjects were 139 Brazilian women selected from a pool of 619 female college students previously classified by levels of achievement (Ach) and affiliative (Aff) needs. The subjects were assigned to three experimental conditions-neutral, affiliation arousal, and achievement arousal—and wrote stories that were analyzed by a projective measure (MPAM). A significant Achievement Level × Treatment Interaction revealed that achievement arousal increased the Ach scores of High Ach subjects but did not affect the scores of Low Ach subjects. Level of affiliative tendencies did not affect these results. Contrary to some of the speculations, achievement arousal did not inhibit the scores of High Ach-High Aff women. Overall, affiliation arousal did not produce the expected effects. However, within the affiliation-arousal condition, High Aff subjects obtained significantly higher scores than Low Aff subjects.     

Self-rated autistic-like traits and capacity of visual working memory

The effect on the capacity of visual working memory of spatial complexity (as defined by Garner's principle) in rotation and reflection transformation was examined in persons differing along the Autism Spectrum Quotient (AQ), using a change-detection task. On each trial, nine line segments were arrayed in simple, medium, and complex configurations, which were presented in memory and test displays. 27 participants (8 men, 19 women; M age = 22.3 yr., SD = 2.7) were asked whether the orientations of stimuli between two displays were the same or different. On the basis of their AQ scores out of 50 (M AQ scores = 20.9, SD = 6.3), the participants were divided into groups with high (n = 13; M AQ scores = 26.2, SD = 4.1) and low (n = 12; M AQ scores = 15.3, SD = 2.7) self-reported autistic-like traits (High and Low AQ groups, 2 excluded for scores at the median). The results showed that spatial complexity affects the capacity of visual working memory for the Low AQ group but not for the High AQ group, suggesting the functional dissociation of spatial configuration and visual working memory in the High AQ group.     

Visual field asymmetries in attention vary with self-reported attention deficits

The purpose of this study was to determine whether an index of self-reported attention deficits predicts the pattern of visual field asymmetries observed in behavioral measures of attention. Studies of “normal” subjects do not present a consistent pattern of asymmetry in attention functions, with some studies showing better left visual field (LVF) performance, others showing no asymmetry or even a right visual field (RVF) advantage. Here we found that a participant variable (a measure of self-reported attention problems) may help to explain these inconsistencies. We used Conners’ Adult ADHD Rating Scales to measure self-reported attention problems in a group of 36 normal (non-ADHD) subjects, and we used two behavioral tasks to directly measure their attentional abilities: a lateralized Attention Network Task (ANT) and a visual search task. Comparing subjects with relatively Low versus High scores on the attention-deficit (AD) scale, we found that subjects with High scores were less efficient in orienting attention to the left visual field. When LVF targets were preceded by a valid spatial cue, response times were positively correlated with AD scores, indicating slower covert-attention shifts as attention-deficit scores increased. Right visual field data showed a different pattern of results. Subjects with High AD scores were at least as efficient as those with Low AD scores in orienting attention to the RVF. This study provides evidence that visual field asymmetries in orienting attention vary across individuals, and that level of self-reported attention problems correlates with behavioral deficiencies in orienting attention to the left visual field.     

Actual versus self-reported scholastic achievement of litigating postconcussion and severe closed head injury claimants

Psychologists typically rely on patients' self-report of premorbid status in litigated settings. The authors examined the fidelity between self-reported and actual scholastic performance in litigating head injury claimants. The data indicated late postconcussion syndrome (LPCS) and severe closed head injury litigants retrospectively inflated scholastic performance to a greater degree than nonlitigating control groups. The LPCS group showed the highest magnitude of grade inflation, but discrepancy scores did not significantly correlate with a battery of malingering measures or with objective cerebral dysfunction. These findings support previous studies, which showed self-report is not a reliable basis for estimation of preinjury cognitive status. Retrospective inflation may represent a response shift bias shaped by an adversarial context rather than a form of malingering.     

Patterns of spontaneous recovery in aphasic groups: A study of adult stroke patients

The recovery of 31 aphasic stroke patients in the first three months postonset was investigated. Improvements on eight comprehension, repetition, and expression tasks were documented for four groups. These groups, retrospectively defined on the basis of initial scores on a fluency and a comprehension task, were: Low Fluency/Low Comprehension (LFLC), Low Fluency/High Comprehension (LFHC), High Fluency/Low Comprehension (HFLC), and High Fluency/High Comprehension (HFHC). Examination of each group's recovery revealed (1) equal improvement on nearly all language tasks for the two High Comprehension groups and (2) a more selective improvement largely in comprehension and imitation tasks for the two Low Comprehension groups. Implications of this selective improvement in initially low comprehending aphasics are discussed.     

Memory performance predicts interrogative suggestibility better than global cognition in older adults with subjective cognitive complaints

The present study aims to investigate to which extent global cognition and verbal memory can estimate interrogative suggestibility (IS) in elderly people with subjective cognitive complaints (SCCs). We used the Gudjonsson Suggestibility Scale (GSS 2) subscales (i.e., Yield 1, Yield 2 and Shift) as measures of IS. Data from a sample of consecutive patients (N = 94) who referred to neuropsychology units for the first time were collected.Our results showed that verbal memory is a better predictor of IS than global cognition. Moreover, memory impairment led to significantly higher IS independently of global cognitive status. These findings suggest that the assessment of verbal memory allows to estimate individual levels of IS better than global cognition, even in elders with objective cognitive deficits. Implications for forensic assessment of senior witnesses are discussed.     

Psychopathy and malingering of psychiatric disorder in criminal defendants

Because the use of deception is an important clinical characteristic of psychopathy, there is intuitive appeal to the idea that psychopathy and malingering are associated. There is, however, very little research showing that psychopaths are more likely to malinger. We classified a sample of criminal defendants as high, moderate, or low in psychopathy, based on PCL-R scores, and compared their scores on indices typically used to detect malingering on the MMPI-2, the PAI and the SIRS. The high psychopathy group scored significantly higher on the MMPI-2 F and F-K; the PAI NIM, and the SIRS, but not the MMPI-2 Fb, F(p), or the PAI RDF or Mal, lending some support for the DSM-IV recommendation that malingering should be considered whenever there is a diagnosis of antisocial personality disorder. Logistic regression analysis (LGA) revealed that Factor I but not Factor II of the PCL-R significantly discriminated malingerers from nonmalingerers with 75% correct classification. However, receiver operating characteristic (ROC) analysis revealed that psychopathy ratings had poor sensitivity and specificity in the detection of malingering. Calculation of the percentages of those exceeding accepted cut-offs on each of the malingering measures revealed that a high percentage of severe psychopaths did not attempt to feign psychiatric disorder. The results suggest that psychopathy is not a clinically useful indictor of malingering. The results are discussed in terms of confirmatory bias and the impact such a bias could have on the evaluation of criminal defendants.     

The impact of expertise and sufficient information on psychologists' ability to detect malingering

Twenty-two forensic diplomates and 22 general clinical psychologists were asked to review a variety of psychological data from one of four cases (two cases of malingering and two cases of legal insanity) to determine whether data suggested malingering or insanity. Of the 44 psychologists who reviewed cases, 86.4% accurately determined whether their protocol was from a malingerer or an insane person. Forensic diplomates and clinical psychologists were equally accurate in their determinations; only three subjects from each group misidentified their case. In spite of their success, confidence levels for both groups were reported as moderate. These results contradict previous studies that have found psychologists to not only be poor detectors of malingering, but also overconfident in their ability to detect it. It is believed that the success of psychologists in this study compared to previous studies was due to improved methodology.     

WAIS digit span-based indicators of malingered neurocognitive dysfunction: classification accuracy in traumatic brain injury

The present study determined specificity and sensitivity to malingered neurocognitive dysfunction (MND) in traumatic brain injury (TBI) for several Wechsler Adult Intelligence Scale (WAIS) Digit Span scores. TBI patients (n = 344) were categorized into one of five groups: no incentive, incentive only, suspect, probable MND, and definite MND. Performance of 1,063 nonincentive patients (e.g., cerebrovascular accident, memory disorder) was also examined. Digit Span scores included reliable digit span, maximum span forward both trials correct, maximum span forward, combined maximum forward and backward span, Digit Span scaled score, maximum span backward both trials correct, and maximum span backward. In TBI, sensitivity to MND ranged from 15% to greater than 30% at specificities of 92% to 98%. Patient groups with documented brain pathology had higher false-positive error rates. These results replicate previous known-groups malingering studies and provide valuable data supporting the WAIS Digit Span scores in detection and diagnosis of malingering.     

A Pursuit Device for Obtaining both Quantitative and Qualitative Records

Fifth and sixth grade students (N = 87) were divided into High Test Anxious and Low Test Anxious groups on the basis of galvanic skin responses (GSR). Ss identified as High Anxious responded positively to group systematic desensitization procedures, exhibiting significantly (p < .05) lower autonomic indices of test anxiety and significantly (p < .001) improved criterion test scores. Low Anxious Ss exposed to the systematic desensitization program demonstrated no significant change in criterion test scores.     

Workload history effects: A comparison of sudden increases and decreases on performance

The present study examined workload history effects by manipulating sudden changes in workload level, and was designed to enable a direct comparison between sudden increasing and decreasing in workload conditions. A sample of 149 undergraduates was randomly assigned to either a sudden decrease or a sudden increase in workload condition. Participants performed a Sternberg memory task while percent correct was recorded. Mixed-model ANOVA results indicated that performance was significantly impaired for both conditions. Findings supported previous research suggesting that either a sudden decrease (High to Medium) or increase (Low to Medium) workload could result in impaired performance (Cox-Fuenzalida, in press; Cox-Fuenzalida & Angie, in press; Cox-Fuenzalida, Swickert & Hittner, 2004). Furthermore, this study suggests that a sudden decrease may result in greater detrimental effects. The authors express their gratitude to the research team from the Personality and Human Performance Research Laboratory at the University of Oklahoma for their invaluable assistance in data planning and collection. Laura Sohl is currently employed with the Oklahoma Office of Personnel Management.

Some Changing Aspects of the Self-Concept of Pubescent Males

Fifty Ss initially rated themselves and a friend on intelligence. Ss were then divided into High and Low Acceptance groups using a self-ideal discrepancy. It was predicted that the High Acceptance group would generally rate themselves higher on the self-concept measures than would the Low Acceptance group. Further, and most importantly, it was predicted that the High group would rate their friend's intelligence as similar to their own, while the Low group would rate their friend higher than themselves and, therefore, closer to their ideal. The predictions were generally supported, although the High group failed to exhibit the expected trait similarity. It was concluded that a trait complementarity model was most appropriate for interpreting the results of both groups.     

Mid-life stress is associated with both up- and down-regulation of markers of humoral and cellular immunity

Perception of stress with consequent activation of a neuroendocrine cascade causes changes in immune function that may be bi-directional, with alterations in basal levels of biological parameters outside the optimal range. In this cross-sectional study of 302 healthy persons (males 56.3%, females 43.7%) aged 41-46 years, higher stress levels, as assessed by questionnaire measures of recurrent and recent perceived stress, were associated with a 4-fold greater risk of having a high compared to mid-range serum neopterin concentration, indicating activation of cellular immune mechanisms [adjusted odds ratio, OR; (95% confidence intervals, CI): Low stress=1.00 (reference group); Medium stress=4.13 (1.51, 11.29); High stress=4.63, (1.35, 15.83), p for trend=0.01]. Higher stress levels were associated with a 3-fold greater risk of having signs of humoral immune activation, as indicated by salivary IgA concentration [high compared to mid-range salivary IgA: Low stress=1.00 (reference group); Medium stress=1.06 (0.48, 2.34); High stress=3.62 (1.26, 10.39), p for trend=0.02], but also a 4-fold greater risk of humoral immune depression [low compared to mid-range IgA: Low stress=1.00 (reference group); Medium stress=1.72 (0.74, 3.99); High stress=4.38 (1.47, 13.00), p for trend=0.02]. In conclusion, in this cross-sectional study, higher stress levels were associated with higher serum neopterin and both elevated and depressed salivary IgA levels. These findings emphasise the importance of considering that stress may have bi-directional effects on immune mechanisms, and are consistent with an activational effect of chronic, perceived stress on cellular immunity, and a bi-directional effect on IgA levels, one aspect of humoral immunity.     

Correlates of malingering

The author presented anonymous questionnaires to 172 patients and 160 medical students to assess the frequency and correlates of malingering in various groups in a medical center on a V.A. campus. The results indicate that sociopaths, drug abusers, and alcoholics are more prone to malinger than other individuals, supporting previous assertions that mental health professionals should have a higher index of suspicion for malingering in these diagnostic groups. Race and age were found to have small but significant correlations with malingering, but at present, this finding must be viewed cautiously. No association was found between somatization disorder and malingering.     

Patterns of intellectual ability in children with verbal deficits

Patterns of intellectual ability were examined in 81 children with verbal deficits identified by a Low Verbal/High Performance WISC profile. The results of verbal and nonverbal tests of intellectual functioning were factor-analyzed, and three groups of children were defined based on patterns of factor scores. Group 1 consisted of children with a Specific Language Disability (SLD) but good Abstract Reasoning ability, while Group 2 included SLD children with good Sequencing-Memory skills. Group 3 children displayed a General Language Disability (GLD) with deficits in both abstract reasoning and sequencing memory. The intellectual patterns were related to cognitive interpretations and found to have educational implications, with Group 1 children reading adequately, Group 2 children showing somewhat poorer reading skills, and Group 3 children reading very poorly. These findings emphasize the importance of identifying subgroups of children with verbal deficits and demonstrate the feasibility of extracting relatively specific cognitive information from global measures of intelligence. The results question the appropriateness of applying traditional assumptions regarding cognitive organization derived from studies of normal children to atypical groups of children.
