Reliability and Validity of a Short Version of the General Functioning Subscale of the McMaster Family Assessment Device

The General Functioning 12‐item subscale (GF12) of The McMaster Family Assessment Device (FAD) has been validated as a single index measure to assess family functioning. This study reports on the reliability and validity of using only the six positive items from the General Functioning subscale (GF6+). Existing data from two Western Australian studies, the Raine Study (RS) and the Western Australian Child Health Survey (WACHS), was used to analyze the psychometric properties of the GF6+ subscale. The results demonstrated that the GF6+ subscale had virtually equivalent psychometric properties and was able to identify almost all of the same families who had healthy or unhealthy levels of functioning as the full GF12 subscale. In consideration of the constraints faced by large‐scale population‐based surveys, the findings of this study support the use of a GF6+ subscale from the FAD, as a quick and effective tool to assess the overall functioning of families.     

Anxiety,coping and academic performance

Anxiety is a frequent response to stressful evaluation situations and may be correlated with the performance being evaluated. The present study investigated individual differences in social evaluation trait anxiety and coping dimensions as predictors of state anxiety and performance on a university examination. Separate multiple regressions were computed for coping assessed as a style, an individual difference measure, and as situational specific responses. Emotion-oriented coping predicted state anxiety in the evaluation situation. Social evaluation trait anxiety and task-oriented and emotionoriented coping responses predicted exam performance. The regression models predicted approximately a quarter of the variance in course grades. When coping was measured as a response, task-oriented coping response was a significant predictor of course grade. When coping was measured as a style or individual difference, avoidance-oriented coping style predicted aggregated course grade. It was suggested that different coping dimensions predict different outcomes and that coping be assessed over time to better understand its relation to performance.     

The association between depressive symptoms and smoking in pregnant adolescents

There have been no studies that have specifically examined the relationship between smoking and depressive symptoms in Australian pregnant adolescents. Eighty one pregnant adolescents completed an adapted version of Lawson's (1994) Smoking Questionnaire and the Edinburgh Postnatal Depression Scale. Smoking status (smokers vs. non-smokers) and depressive symptoms remained stable during pregnancy. However, comparisons of depressive symptoms across smoking categories revealed that pregnant adolescent smokers were more likely to be depressed than pregnant adolescent lifetime non-smokers, particularly in the later stages of pregnancy. There was a weak association between the number of cigarettes smoked and depressive symptoms, but only in the third trimester. Recommendations include further examination of the association between depression or depressive symptoms and smoking, and investigation of how change in smoking status during pregnancy may effect depression.     

Skilled adult readers activate the meanings of high-frequency words using phonology: Evidence from eye tracking

We examined whether highly skilled adult readers activate the meanings of high-frequency words using phonology when reading sentences for meaning. A homophone-error paradigm was used. Sentences were written to fit 1 member of a homophone pair, and then 2 other versions were created in which the homophone was replaced by its mate or a spelling-control word. The error words were all high-frequency words, and the correct homophones were either higher-frequency words or low-frequency words—that is, the homophone errors were either the subordinate or dominant member of the pair. Participants read sentences as their eye movements were tracked. When the high-frequency homophone error words were the subordinate member of the homophone pair, participants had shorter immediate eye-fixation latencies on these words than on matched spelling-control words. In contrast, when the high-frequency homophone error words were the dominant member of the homophone pair, a difference between these words and spelling controls was delayed. These findings provide clear evidence that the meanings of high-frequency words are activated by phonological representations when skilled readers read sentences for meaning. Explanations of the differing patterns of results depending on homophone dominance are discussed.     

Training Employment Acquisition Skills for Adolescents with a Substance Abuse History

Obtaining paid employment is beneficial for youth during and following treatment for substance abuse. A training program for acquiring employment was implemented at a residential drug and alcohol rehabilitation facility for nine residents who were near to completing the program. Data are presented from three residents with the most complete data sets. Skills training was provided for completing biographic information on job application forms, job searching by telephone and in person, and job interviews. The training process included behavioral procedures of providing instructions, modeling, role‐play, and feedback. Improvements were demonstrated across all behaviors and participants after the training and generalized to real community materials and settings. All participants who remained in treatment also gained real work experience opportunities or regular paid employment. Copyright © 2011 John Wiley & Sons, Ltd.     

An exploration of personality-affect relations in daily life: Determining the support for the affect-level and affect-reactivity views

The two strongest predictors of affect are extraversion and neuroticism. Previous research has demonstrated the extraversion-positive affect and neuroticism-negative affect relations are both strong and positively correlated. To explain these relations, researchers have hypothesized two extensions of the temperament model: the affect-level and affect-reactivity hypotheses of well-being. We used retrospective diaries to examine the support for these hypotheses and, across all three studies, we found strong support for the affect-level model - that is, extraversion predicted a consistent increase in positive affect, neuroticism tended to predict a consistent increase in negative affect. Further, these paths were significant even after controlling for the normative enjoyment and stressfulness of daily activities. In the discussion we describe how these relations provide support for the affect-level model of well-being.     

Memory and brain volume in adults prenatally exposed to alcohol

The impact of prenatal alcohol exposure on memory and brain development was investigated in 92 African-American, young adults who were first identified in the prenatal period. Three groups (Control, n=26; Alcohol-related Neurodevelopmental Disorder, n=36; and Dysmorphic, n=30) were imaged using structural MRI with brain volume calculated for multiple regions of interest. Memory was measured using the Verbal Selective Reminding Memory Test and its nonverbal counterpart, the Nonverbal Selective Reminding Memory Test, which each yielding measures of learning and recall. For both Verbal and Nonverbal Recall and Slope, linear trends were observed demonstrating a spectrum of deficits associated with prenatal alcohol exposure. Dysmorphic individuals performed significantly poorer than unexposed controls on 5 of 6 memory outcomes. Alcohol-exposed individuals demonstrated significantly lower total brain volume than controls, as well as lower volume in a number of specific regions including hippocampus. Mediation analyses indicated that memory performance associated with effects of prenatal alcohol exposure was mediated from dysmorphic severity through hippocampal volume, particularly right hippocampus. These results indicate that the association between the physical effects of prenatal alcohol exposure and deficits in memory are mediated by volumetric reduction in specific brain regions.     

Constraints on Multiple Object Tracking in Williams Syndrome: How Atypical Development Can Inform Theories of Visual Processing

The ability to track moving objects is a crucial skill for performance in everyday spatial tasks. The tracking mechanism depends on representation of moving items as coherent entities, which follow the spatiotemporal constraints of objects in the world. In the present experiment, participants tracked 1 to 4 targets in a display of 8 identical objects. Objects moved randomly and independently (moving condition), passed behind an invisible bar (occluded condition), or momentarily disappeared by shrinking (implosion condition). Scholl and Pylyshyn (1999) found that adults can track entities under the moving and occluded conditions, but not under implosion. This finding suggests that the tracking mechanism is constrained by the spatiotemporal properties of physical objects as they move in the world. In the present study, we adapt these conditions to investigate whether this constraint holds for people with severe spatial impairments associated with Williams syndrome (WS). In Experiment 1, we compare the performance of individuals with WS and typically developing (TD) adults. TD adults replicated Scholl and Pylyshyn’s findings; performance was no different between the moving and occluded conditions but was worse under implosion. People with WS had reduced tracking capacity but demonstrated the same pattern across conditions. In Experiment 2, we tested TD 4-, 5-, and 7-year-olds. People with WS performed at a level that fell between TD 4- and 5-year-olds. These results suggest that the multiple object tracking system in WS operates under the same object-based constraints that hold in typical development.
