Differences in the Prevalence,Severity and Symptom Profiles of Depression in Boys and Adolescents with an Autism Spectrum Disorder versus Normally Developing Controls

The prevalence, severity and symptom profiles for major depressive disorder (MDD) were compared in samples of boys and adolescents with and without an autism spectrum disorder (ASD). Self-reports were obtained on the Depression subscale of the Child and Adolescent Symptoms Inventory (CASI-D) with 70 ASD and 50 non-ASD male participants between the ages of 8 and 18 from Queensland, Australia who were matched for age and IQ. Results indicated that the ASD participants had significantly higher total CASI-D scores, a greater proportion of participants who qualified for a diagnosis of MDD, and over 50% higher scores for 8 of the 10 CASI-D symptoms than non-ASD participants. The MDD profiles for the ASD participants were dominated by anhedonia. Issues for assessment and diagnosis of comorbid MDD in young males with an ASD, plus targeted treatment planning that directly addresses their MDD profile, are discussed.     

How is Challenging Behaviour Associated with Depression in Boys with an Autism Spectrum Disorder?

The association between aberrant behaviour and depression was examined in a sample of 150 young males with Autism Spectrum Disorder via parent ratings on the Aberrant Behavior Checklist (ABC) and the Major Depressive Disorder subscale of the Child and Adolescent Symptom Inventory (CASI-4-D). Although several subscales of the ABC were significantly correlated with CASI-4-D scores, only the Irritability subscale was a significant predictor of CASI-4-D, but with different patterns of association across younger (6–12 years) and older (13–18 years) participants. When examined at an individual ABC item level, adolescents’ depression was primarily predicted the presence of temper tantrums that were associated with the introduction of variability or frustration at not getting his or her own way.     

Making mathematical meaning through dialogue: ``Once you think of it, the Z minus three seems pretty weird'

In our ongoing qualitative classroom research, we adopt a sociocultural perspective to investigate discourse, and its role in how children and teachers make meaning of mathematics in a fifth grade inquiry classroom. Our theoretical perspective draws primarily on Vygotsky (1978, 1986) and Bakhtin (1981, 1986) each of whom examines how social forms of meaning influence individual cognition. The episode described in this paper examines the process whereby individual and group developmental trajectories are constructed, and allows us to explore the relationship between discourse and knowing. We combine a longitudinal design with a case study approach to focus on the collaborative mathematical problem solving. We use video capture to help us listen to children's discussions in classroom activities and small group interactions. Our analysis of the verbal data recorded on video identifies patterns of interaction, development and change in participants' use of mathematical language and concepts, and their evolving understanding, through discussion and argument, of an algebraic expression constructed by one of the children. The findings lead us to argue for i) a more generative view of the zone of proximal development as a site of learning and of identity formation, ii) an expanded view of the role of the teacher in inquiry classrooms, and iii) an appreciation for the valuable roles difference and resistance play in knowledge building.     

Teachers' beliefs about pedagogy and related issues

This study explores teachers' beliefs about pedagogical issues as well as related educational and professional issues. Six hundred K–12 teachers in three Midwestern states received surveys and 60% returned them. Results of the survey indicated that teachers were relatively unified in their beliefs, and few differences emerged around demographic variables. More teachers believed in teaching practices consistent with constructivism than believed in explicit instruction; however the majority of teachers were mixed, undecided, or balanced about pedagogy. Teachers reserved their strongest beliefs for the importance of learning style, eclectic instruction, and small class size in the primary grades. Few teachers believed that a great teacher is characterized by high student achievement outcomes, and over half believed that factors such as home environment or dyslexia prevent children from learning basic skills despite the school's best efforts. Teachers valued experience over education and training for professional development and viewed teaching as more of an art than a science. Results are discussed in relationship to current challenges in education. © 2007 Wiley Periodicals, Inc. Psychol Schs 44: 873–886, 2007.     

Searching the Polish Medical Bibliography (Polska Bibliografia Lekarska) for trials

Background: The Polish Medical Bibliography (Polska Bibliografia Lekarska) contains 350 000 records dating from 1979. These records from the fields of medicine, nursing, dentistry, health care systems and preclinical sciences are from nearly 300 biomedical journals published in Poland. Methods: We systematically searched the Polish Medical Bibliography Part II (1996–2006) CD‐ROM (July 2006) using both English and Polish phrases for randomized trials, manually checked results and, for the trials identified in this way, sought these on medline and embase . Results: Systematic searching identified records of 680 randomized trials from all areas of health care. Nearly 40% of these were not found on either medline or embase . Conclusions: The Polish Medical Bibliography should be of interest to health care information specialists concerned with comprehensive searches for trials.     

Self-Study as a Means for Urban Teachers to Transform Academics

Our self-study has two main purposes: (1) to understand the value of self-study for credential program graduates to confront in transformative ways the pedagogical challenges of urban schools, and (2) to add to an exploration of self-study for non-teacher educators and strengthen our preparation of candidates to enact such inquiry. To answer these questions, we orchestrated a dialogic exchange with three Master's students who used self-study to research and improve their teaching in urban elementary schools. We analyzed their papers both to see how consistent they were with the characteristics of self-study and to determine the nature of lessons learned in relation to our social justice goals. In addition, in the following year we gathered and analyzed information about their post-study reactions to self-study and its continuing influence. In their self-studies all three examined assumptions guiding their teaching by analyzing pertinent data and functioning as critical friends for each other; their work was consistent with self-study requirements. Written reflections and interviews all mentioned the transformative influence of self-study on their thinking and practice. We also discovered that we should strengthen our guidance with regard to the specifics of self-study methodology, as in the need to look for disconfirming evidence. Although their commitment to the process was maintained, we need to explore whether and how self-study might be engaged more informally. Overall, we found that self-study invites teachers to question discriminatory categories with empirical evidence and empowers them to redefine their profession and question regressive policies.     

Conflict in the Dyadic Play of 3-Year-Old Children

Episodes of conflict provide a rich source of information about children's development of interactive skills. In the present study, 184 3-year-old children were observed in dyadic play and the 287 conflicts that occurred during their play were transcribed and coded. In general, children's conflicts arose in the context of ongoing play and were brief, lasting less than 15 seconds. Most disputes concerned toy possession, and almost 80% were ended by the simple withdrawal of one or the other children from the conflict. When children responded with emotional intensity to conflict, their conflicts lasted longer and were more likely to be followed by continued negative interaction. Individual difference data were available for one member of each dyad observed in play. Children rated in infancy as having difficult temperaments were found to be more intense during conflict, to spend more time in conflict, and to score higher on an index of conflict resolution competence, whereas concurrent social behavior was not related to conflict variables. Girls scored higher than boys on competence at conflict resolution, and children with better language skills spent less time in conflict. The more time children spent in nonmaternal child care up to age 3, the less likely they were to initiate conflict.
