Intimate Partner Violence Risk Factors: A Vulnerability-Adaptation Stress Model Approach

Intimate partner violence (IPV) disproportionally affects women. Using the vulnerability-adaptation stress model, we examined adverse childhood experiences (ACEs), self-esteem, and hope as vulnerability indicators and relationship status and length, positive and negative affect, and socioeconomic status (SES) as stressors to ascertain the risk for IPV. Women (N = 491, M = 37.15, standard deviation = 12.51) completed an online survey comprised of the Positive and Negative Affect Scale, Rosenberg's Self-esteem Scale, Snyder's Hope Scale, ACE questionnaire, Composite Abuse Scale Revised-Short Form, and demographic questions. Factor analysis identified four ACE factors of sexual abuse, physical or psychological abuse, witnessing domestic violence, and household dysfunction. A five-step hierarchical multiple regression identified that greater exposure to physical or psychological child abuse was associated with an increased risk of IPV (Step 2), B = 0.73 [0.16, 1.34]. Lower self-esteem, B = -0.30 [-0.47, -0.14] predicted IPV (Step 3). Age B = 0.07 [0.01, 0.13], negative affect, B = 0.39 [0.19, 0.59], and relationship length, B = -1.24 [-2.16, 0.41] were associated with a higher risk of IPV (Step 4). In Step 5, previous variables attenuated to non-significance while age, B = 0.07 [0.01, 0.13], negative affect, B = 0.39 [0.19, 0.59], and relationship length B = -1.25 [-2.16, 0.41] remained significant. While the key findings of this study were inconsistent with some commonly reported findings (e.g., ACEs, self-esteem, hope, relationship status, SES, age), these inconsistencies are important to highlight given the factorial approach to examining ACEs, the comprehensive analyses conducted, and our examination of these variables' direct relationship to IPV. The study was limited by its cross-sectional nature, higher prevalence of IPV victims, and not examining IPV sub-types. Similar studies need to be conducted for other relationship types and victimized individuals (e.g., same-sex relationships and male victims) to provide a complete picture of risk factors for IPV.

Examining the relationship between maternal childhood abuse history and mother-infant bonding: The mediating roles of postpartum depression and maternal self-efficacy

BACKGROUND

The detrimental effects of childhood abuse on long-term outcomes are well-known, however few studies have examined these effects in the context of postpartum psychopathology, maternal self-efficacy, and mother-infant bonding quality.

OBJECTIVE

This study aimed to examine the relationship between a maternal childhood abuse experience (i.e., physical, psychological, and sexual) and mother-infant bonding disturbances, and whether this relationship was mediated by postnatal depression symptomatology and maternal self-efficacy.

METHOD

A sample of 191 postpartum women (Mage = 32.88, SD = 4.20) recruited online from the general population completed self-report measures of the constructs of interest.

RESULTS

Postnatal depression symptomatology and maternal self-efficacy were found to fully mediate the relationship between psychological child abuse experience and mother-infant bonding disturbances (β = 0.06, SE = 0.03, 95% CI: 0.01, 0.12). Postnatal depression symptomatology (but not maternal self-efficacy) was an independent mediator between psychological child abuse experience and mother-infant bonding (β = 0.07, SE = 0.03, 95 % CI: 0.01, 0.13). After inclusion of other abuse types as covariates in the analyses, the findings for maternal child physical abuse attenuated to non-significance. Child sexual abuse was not associated with the mediating or outcome variables, highlighting the issue of disclosure despite the anonymous online environment.

CONCLUSION

This study highlights the negative impact of psychological childhood abuse experience on the quality of the mother-infant bond during the postpartum period and potential pathways that underlie this relationship. This study also draws attention to the need to recognize comorbidity of abuse types in research.

Validation of the German version of the pregnancy-related anxiety scale (PrAS): psychometric properties across all trimesters of pregnancy

BACKGROUND

Pregnancy-related anxiety has received greater research attention recently given its association with adverse outcomes (e.g., negative birth experiences). The Pregnancy-related Anxiety Scale (PrAS) offers the possibility to assess pregnancy-related anxiety, but no German version is available. Therefore, the aim of this study was to validate a German version of the PrAS, a comprehensive measure with eight dimensions.

METHODS

Pregnant women of any parity or gestation completed an online survey consisting of the PrAS, PRAQ-R2, and measures of anxiety, depression, and resilience. The PrAS was translated into German (PrAS-G) using the back-translation method. Data were subjected to confirmatory factor analysis and inferential statistics.

RESULTS

Complete data were provided by 443 women. Participants were predominantly German nationals, partnered, and well-educated with a planned pregnancy. Approximately half were nulliparous. The eight-factor model was well fitting and consistent with the development of the original PrAS. Criterion-related validity was demonstrated by strong correlations with similar measures (PRAQ-R2, anxiety, and depression) and lower correlations with resilience scores. Predictive validity was shown by group comparisons for: planned versus unplanned pregnancy, trimester, and parity.

CONCLUSIONS

The PrAS-G provides a broader assessment of pregnancy-related anxiety than existing measures. Initial evaluation has demonstrated convergent, divergent, and predictive validity, excellent internal consistency, and good model fit indicating promising psychometric properties. The PrAS-G offers a comprehensive assessment of pregnancy-related anxiety which will enable tailored interventions aiming to improve birth experience and well-being of expectant mothers.

Child abuse and wellbeing: Examining the roles of self-compassion and fear of self

INTRODUCTION

Childhood abuse is linked to poorer well-being, yet some survivors show no prolonged effect, suggesting multifinality. Men and women also differ in the experience and sequelae of abuse supporting gender-specific analyses. To assist in circumventing poor outcomes associated with child abuse, this study examined fear of self (FoS) and self-compassion (SC) as risk and protective factors between child abuse and well-being.

METHOD

Australian women (N = 1302, M_age = 47.28 [13.63]) completed an online assessment of childhood abuse, psychological distress, perceived quality of life, SC, FoS. Moderated-moderation examined the different abuses as predictors of psychological distress and quality of life (QoL) and FoS and SC as primary and secondary moderators, respectively.

RESULTS

Physical abuse did not predict psychological distress or QoL. FoS and SC were independent predictors of distress and QoL. Similarly, childhood sexual abuse was not found to predict distress or QoL. FoS and SC were independent predictors of distress and QoL. There was also an interaction between childhood sexual abuse and SC in predicting QoL. A moderated-moderation was found for the relationship between child sexual abuse and distress. Psychological abuse predicted distress and QoL, and FoS and SC both moderated this relationship. Moreover, a moderated-moderation was observed for the relationship between psychological abuse and QoL.

CONCLUSIONS

Greater FoS is associated with poorer outcomes for child abuse survivors; SC may mitigate this impact. Psychological abuse was the strongest predictor of well-being. Interventions that increase SC and raise awareness of psychological abuse and its impacts are needed.

Alcohol consumption after pregnancy awareness and the additive effect of pregnancy-related anxiety and child abuse

This study examined whether pregnant women alter their alcohol consumption upon pregnancy awareness and any additive effect of a maternal history of child abuse and pregnancy-related anxiety in predicting antenatal alcohol consumption. Pregnant women (N = 548, M = 31.44, SD = 4.58) completed an online survey consisting of the Pregnancy-related Anxiety Scale, Adverse Childhood Experience Questionnaire, questions on alcohol consumption and demographics. The Wilcoxon test examined difference scores between pre-pregnancy awareness and post-awareness drinking. More women reduced or ceased drinking after pregnancy awareness (M = 0.15, SD = 1.03) than before pregnancy recognition (M = 3.12, SD = 3.91). Only two women increased their alcohol consumption, with 140 reporting no change. In the hierarchical regression analysis, child abuse was not significant in the model, whereas pregnancy-related anxiety predicted alcohol consumption, with pre-pregnancy drinking the strongest predictor. There was no significant interaction effect between pregnancy-related anxiety and child abuse. While limited by a cross-sectional design and single questions to assess alcohol intake, our findings are consistent with extant literature. Findings related to child abuse were not significant, and likely due to low prevalence in the sample, Despite this, we further established that pregnancy-related anxiety remains a significant predictor of antenatal drinking regardless of how much alcohol a woman may consume pre-pregnancy. This relationship may be explained by drinking used to cope with pregnancy-related anxieties. While current guidelines recommend alcohol screening, many women may not accurately report their alcohol intake screening for pregnancy-related anxiety may provide an avenue to identify women more at risk of drinking during pregnancy.

Paternal pregnancy-related anxiety: Systematic review of men's concerns and experiences during their partners' pregnancies

BACKGROUND

Up to 25 % of expectant parents experience anxiety symptoms. Pregnancy-related anxiety is characterised by concerns and worries specific to pregnancy, childbirth, and the transition to parenthood. While pregnancy-related anxiety is well-researched in women, the exact nature of this construct in men is unclear. The purpose of the current review was to examine men's concerns, worries, and fears during pregnancy and gain an understanding of their experiences during pregnancy.

METHODS

An integrative review design was adopted, using thematic content analysis to synthesise findings from quantitative and qualitative studies. Quality appraisal of the quantitative studies used the AXIS appraisal tool. The Critical Appraisal Skills Program (CASP) checklist was used for the qualitative studies.

RESULTS

A comprehensive search of nine databases led to inclusion of 14 quantitative and 41 qualitative studies. Ten dimensions of paternal pregnancy-related anxiety were identified: childbirth concerns, attitudes towards childbirth, baby concerns, acceptance of pregnancy, partner concerns, relationship concerns, worry about self, transition to parenthood, attitudes towards health care professionals, and practical and financial concerns. The pregnancy transition was characterised by mixed emotions and conflicted experiences for fathers.

LIMITATIONS

Generalizability of review findings was limited by poor reporting of demographic information by many included studies, exclusion of studies not published in English, and focus on heterosexual relationships.

CONCLUSIONS

Expectant fathers may experience anxiety symptoms characterised by excessive worry across multiple domains of pregnancy-related concerns. Clinicians play an important role in identifying and supporting fathers with pregnancy-related anxiety and addressing the sense of exclusion often experienced by them.

Screening for Pregnancy-Related Anxiety: Evaluation of the Pregnancy-Related Anxiety Scale-Screener Using Rasch Methodology

Pregnancy-related anxiety has been linked to many maternal and child-related negative outcomes. However, there is an absence of free, well-validated screeners for this condition. The Pregnancy-related Anxiety Scale-Screener (PrAS-Screener) was evaluated using robust Rasch methodology. This study also aimed to develop a shorter version to meet the need of settings governed by professional guidelines stipulating the use of brief instruments. Data from 400 pregnant women (M_age = 27.82, SD = 5.38) were subjected to Rasch analyses and the resulting Rasch models confirmed in a second sample (N = 400, M_age = 26.29, SD = 4.95). After minor modifications, the original 15-item PrAS-Screener demonstrated good fit, unidimensionality, excellent targeting, invariance, and internal consistency. After removal of items with content overlap, an 11-item version was developed, with this version showing good fit, unidimensionality, reasonable targeting, and sound internal consistency. The PrAS-Screeners show promise as psychometrically sound clinical scales for screening pregnancy-related anxiety.

Psychometric properties of the Pregnancy-Related Anxiety Scale-Screener

Pregnancy-related anxiety, a distinct anxiety characterized by pregnancy-specific concerns, has consistently been associated with adverse birth outcomes and obstetric and pediatric risk factors. Despite this, widespread screening for pregnancy-related anxiety has not been integrated into routine antenatal care likely due to the absence of a psychometrically sound screener. This study reports on the initial development of a brief screener derived from the 32-item pregnancy-related anxiety scale (PrAS). Three datasets (comprising pregnant women recruited online) were utilized in the development and evaluation of the PrAS screener (PrAS-Screener). Dataset one (N = 1,084) was used to derive two potential screeners from the PrAS using principal axis factoring (PAF). The factor structure of the models was evaluated using PAF and model fit assessed with confirmatory factor analysis (CFA) using datasets two (N = 638) and three (N = 581). The model comprised 15 items and five subscales was selected as the superior model. The selected model (i.e., PrAS-Screener) was evaluated for convergent and discriminant validity demonstrating higher correlations with similar measures and lower correlations with dissimilar measures and high internal consistency reliability (α = .93). The PrAS-Screener assesses the three core areas of pregnancy-related anxiety (childbirth, body image, baby concerns) but has the advantage of also assessing anxiety symptoms and medical staff concerns, an area integral to providing optimal antenatal care through trusted relationships with clinicians. Initial evidence indicates that the PrAS-Screener is promising as a brief and easy-to-administer screener suitable for use in routine antenatal care.

Psychometric evaluation of the pregnancy-related anxiety scale: Acceptance of pregnancy, avoidance, and worry about self subscales

BACKGROUND

Increasingly pregnancy-related anxiety is acknowledged as a distinct anxiety type, characterised by specific fears/worries. The Pregnancy-related Anxiety Scale (PrAS) screens for this distinct anxiety and refinements to the scale have prompted further validity examination. This study aims to: replicate findings that distinguished pregnancy-related anxiety from general anxiety/depression using the PrAS; confirm the PrAS's factor structure, and examine the validity of the PrAS subscales: Acceptance of Pregnancy, Avoidance and Worry About Self.

METHODS

Pregnant women (N = 608) were recruited online and completed the PrAS, Pregnancy Acceptance Questionnaire, Ways of Coping Questionnaire, Cambridge Worry Scale, Parenting Sense of Competence Scale, State Trait Anxiety Inventory and the Edinburgh Depression Scale.

RESULTS

Multiple regression analysis confirmed general anxiety/depression contributed little to the PrAS's variance, supporting the scale's validity and distinctiveness of pregnancy-related anxiety. Structural equation modelling confirmed the PrAS's factor structure, and the three PrAS subscales generally correlated more highly with convergent measures than the discriminant measures.

LIMITATIONS

Limitations included the cross-sectional design of the study and the use of some convergent/discriminant measures that lacked validity evidence for prenatal use.

CONCLUSIONS

This study provides evidence of the distinctiveness of pregnancy-related anxiety from state/trait anxiety and depression and also adds to the psychometric properties of the PrAS. The PrAS is a useful screening scale that can be used for antenatal screening potentially reducing the risk of adverse outcomes associated with pregnancy-related anxiety. The PrAS is also a useful research tool providing a more comprehensive assessment of pregnancy-related anxiety.

Child Sexual Abuse and Pregnancy: A Systematic Review of the Literature

BACKGROUND

Child sexual abuse is related to many negative outcomes but less known is the effect on pregnancy and childbirth.

OBJECTIVE

This review critically examined the literature on the occurrence of child sexual abuse and outcomes associated with this abuse during pregnancy and childbirth.

METHODS

Five databases were searched over 50 years using an iterative approach and the terms pregnancy, sexual abuse/assault, childbirth/labour, identifying 49 studies.

RESULTS

The prevalence of child sexual abuse in pregnant women ranged from 2.63% to 37.25 with certain characteristics more common with a higher (e.g., specific questions, low income) or lower (broad questions, higher education) prevalence. Compared to women with no history of abuse, child sexual abuse survivors may have more concerns with their care, greater health complaints, fear childbirth and have difficulties with delivery. They also had a higher likelihood of PTSD symptomology and anxiety, consumed more harmful substances (e.g., alcohol, cigarettes, and drugs) and had greater concerns with their appearance, poorer health, sleep and may also have a higher risk of re-victimisation.

CONCLUSIONS

The balance of evidence suggests that compared to non-abused women, women with a child abuse history have more adverse experiences with pregnancy, childbirth, and care, with their abuse history, likely contributes to harmful behaviours and psychopathology. However, variability in operationalisation and measurement of abuse may contribute to these findings so tentative conclusions are drawn. Future research should examine the generalisability of the findings (relating to scale limitations) and recommendations for screening (e.g., sensitive items, scoring). Clinical implications of the findings point to the need for early identification of women with a child abuse history as such women require trauma-sensitive care and consideration. A useful tool is the Pregnancy-related Anxiety Scale which provides insights into specific areas of concern.

Childhood abuse, pregnancy-related anxiety and the mediating role of resilience and social support

Physical, sexual and psychological abuse were examined as risk factors for pregnancy-related anxiety with resilience and social support as mediators. Pregnant women ( n = 638) completed measures of pregnancy-related anxiety, resilience, perceived social support and childhood abuse. Women with an abuse history had higher pregnancy-related anxiety scores ( m = 64.40) than other women ( m = 55.36). All abuse types independently predicted pregnancy-related anxiety; resilience and social support were mediators. Results highlight the value of antenatal screening for pregnancy-related anxiety including specific risk factors such as child abuse. Programs such as the Midwife Continuity of Care are useful in encouraging disclosure.

Body dissatisfaction and Fat Talk during pregnancy: Predictors of distress

BACKGROUND

During pregnancy, women are vulnerable to mood and anxiety disorders due to the significant physical and emotional changes that occur during this period. For some women, pregnancy can also present as a period of immense body dissatisfaction due to the substantial changes in body shape and size.

OBJECTIVES

This study examined the mediating role of Fat Talk (i.e., engaging in disparaging comments about one's body shape and size with others) in the relationship between (a) body dissatisfaction and distress in pregnant women (i.e., pregnancy-related anxiety, depression and eating disorder symptomatology), and (b) sociocultural pressure to meet the thin ideal and distress.

METHOD

A nonclinical sample of 408 pregnant women (M_age = 28.24 years, SD_age = 5.04, range 18-44 years) completed measures of body dissatisfaction, sociocultural pressure, pregnancy-related anxiety, depression and eating disorder symptomatology.

FINDINGS

Analyses confirmed the partial mediating role of Fat Talk between body dissatisfaction and all three measures of distress, when examined individually. Fat Talk also mediated the relationship between sociocultural pressure (i.e., peers/family and media) and the three measures of distress. Age also partially mediated the relationship between body dissatisfaction and a composite measure of pregnancy distress.

CONCLUSIONS

The results suggest that women face sociocultural pressures for thinness and body dissatisfaction even when pregnant, and that engaging in Fat Talk contribute to greater levels of pregnancy-related anxiety, depression and eating disorder symptomatology. The role of Fat Talk in regard to pregnancy distress may be more pertinent to younger women.

Differentiating Autism Spectrum Disorder From ADHD Using the Social Communication Questionnaire

OBJECTIVE

This study examined the ability of the Social Communication Questionnaire (SCQ) to differentiate between autism spectrum disorder (ASD), ADHD, and typically developing (TD) children.

METHOD

Children ( M_age = 11.27 years, SD_age = 3.28) identified with ASD Severity Levels "1" and/or "2" ( n = 28), ADHD ( n = 44), dual diagnoses of ADHD and ASD ( n = 29), and TD ( n = 61) were assessed using the SCQ.

RESULTS

The SCQ differentiated between ASD and non-ASD groups. Children with ASD had higher total and domain scores on the SCQ than ADHD and TD children. The optimal cutoff total score of 13 was identified for differentiating between ASD and ADHD groups (area under the curve [AUC] = .96). Twenty eight of the 39 items were identified as significant in differentiating between ASD and ADHD.

CONCLUSION

The SCQ continues to be a well-validated screening tool for ASD and is suitable for determining whether further ASD assessment is warranted in children with ADHD symptoms.

The pregnancy-related anxiety scale: A validity examination using Rasch analysis

BACKGROUND

Pregnancy-related anxiety is increasingly recognised as a common condition that is associated with many deleterious outcomes for both the mother and infant (e.g., preterm birth, postnatal depression). Limitations in the psychometric properties and/or breadth of existing scales for pregnancy-related anxiety highlight the need for a psychometrically sound measure to facilitate effective screening and possible early interventions. The recently developed Pregnancy-related Anxiety Scale (PrAS) was evaluated using Rasch analysis to explore how the scale's psychometric properties could be fine-tuned.

METHOD

A sample of 497 pregnant women completed the PrAS. Data were subjected to Rasch analysis, and the resulting scale structure examined using Confirmatory Factor Analysis.

RESULTS

After minor modifications, the Rasch model with 33-items and 8-factors demonstrated good fit, unidimensionality and excellent targeting and internal consistency. Confirmatory Factor Analysis confirmed the final structure, and Cronbach's alpha demonstrated excellent reliability.

LIMITATIONS

The use of the same sample for all analyses was a potential limitation due to the possibility of sample-specific influences.

CONCLUSIONS

The Rasch analysis further supports the internal construct validity of the PrAS. Ordinal to interval score conversions provide added precision to the analysis of the PrAS scores. The Rasch results, together with previous validation evidence, point to the PrAS as a comprehensive and psychometrically sound screening scale for pregnancy-related anxiety. The PrAS offers clinicians the ability to screen for pregnancy-related anxiety. The subscales provide additional insights into a woman's pregnancy-related anxiety and her specific areas of concern, enabling more targeted interventions.

The Role of Sociocultural Influences on Symptoms of Muscle Dysmorphia and Eating Disorders in Men, and the Mediating Effects of Perfectionism

This study examined the mediating role of self-oriented and socially prescribed perfectionism in the relationship between sociocultural influences (i.e., media, peer, and teasing) and symptoms of muscle dysmorphia (MD) and eating disorders (ED). A nonclinical sample of males (N = 158, Mage = 26.94, SD = 5.50) completed measures of perfectionism, MD, body dissatisfaction, drive for thinness, and bulimia. Susceptibility to appearance-based messages from the media, their peers, and family was also measured. Analyses confirmed the partial mediating role of self-oriented perfectionism only for drive for thinness. In contrast, socially prescribed perfectionism was found to be a partial mediator between all three sociocultural variables and measures of both MD and ED; except for those between peer influence and body dissatisfaction, and teasing and bulimia symptomatology. These two relationships were fully mediated by socially prescribed perfectionism. Results suggest that vulnerability to MD and ED depend on pre-existing perfectionistic attitudes, particularly that of socially prescribed perfectionism.

Pregnancy anxiety: A systematic review of current scales

BACKGROUND

Depression in pregnancy is a serious health issue; however, anxiety in pregnancy, with a reported higher prevalence, may also be a serious issue. Anxiety symptoms in pregnancy can relate to several anxiety types, such as general anxiety, anxiety disorders, and pregnancy-related anxiety (PrA), anxiety characterised by pregnancy specific fears and worries. Awareness of these distinctions however, is not always widespread. Both general anxiety and PrA are associated with maternal negative outcomes (e.g. increased nausea) however; PrA is more often associated with negative outcomes for the child (e.g. preterm birth). Furthermore, PrA is potentially a risk factor for postnatal depression with assessment of PrA potentially affording important intervention opportunities. Currently several different instruments are used for PrA however their psychometric properties are unclear. To our knowledge a review of current instruments and their psychometric properties is lacking, this paper aims to fill that gap.

METHODS

Studies, which assessed PrA, published between 1983 and 2013 in peer-reviewed journals, were identified.

RESULTS

Sixty studies were identified after applying inclusion/exclusion criteria, and classified as: pregnancy-related anxiety specific, scales for other constructs, sub scales of another instrument and general anxiety scales. Each scale's strengths and limitations were discussed.

LIMITATIONS

Our findings may be limited by restricting our review to peer-reviewed journals. This was done however as we sought to identify scales with good psychometric properties.

CONCLUSIONS

Currently no scales are available for pregnancy-related anxiety with sound theoretical and psychometric properties. Clinically the need for such a scale is highlighted by the potential intervention opportunities this may afford. Future research should be directed towards the development of such a scale.

Cross-cultural examination of beliefs about the causes of bulimia nervosa among Australian and Japanese females

OBJECTIVE

To identify similarities and differences in beliefs about the causes of Bulimia Nervosa (BN) held by Asian (Japanese) women and Western (Australian) women, and hence, to examine the applicability of belief models of eating disorders (ED) across different cultures.

METHOD

Four hundred three Japanese and 256 Australian female university students (aged 17-35 years) completed a questionnaire that gauged beliefs about the causes of BN.

RESULTS

Among the Australian women, the four-component structure of perceived causes (dieting and eating practices, family dynamics, socio-cultural pressure, and psychological vulnerability) found in Dryer et al. (2012) was replicated. Among the Japanese women, however, a three-component structure (without the psychological vulnerability component) was obtained. The groups also differed in the causal component they most strongly endorsed, that being socio-cultural pressure for the Australian women, and dieting and eating practices for the Japanese women.

DISCUSSION

The Japanese participants were found to endorse three out of the four Western-based causal explanations for BN, but the relative importance they placed on those explanations differed from that of the Australian participants. Further research is needed, particularly to establish whether Japanese women simply fail to see psychological vulnerability as a viable cause of BN, or there are in fact cultural differences in the extent to which such vulnerability causes BN.

The predictors of distress in parents of children with autism spectrum disorder

BACKGROUND

It is well recognised that parents of children with autism spectrum disorder (ASD) often experience clinically significant levels of stress and depression. This study examined which ASD characteristic best predicted parental distress.

METHOD

Parents of 109 children aged between 4 and 12 (M age = 7.89, SD = 2.43) completed self-report measures of anxiety, depression, stress, and parenting-specific stress. They also completed rating scales regarding their child's ASD characteristics.

RESULTS

This study found that the child's behavioural and emotional impairments predicted the parents' overall levels of distress (i.e., stress/tension, anxiety, and depression), but not the stress associated with parenting. Instead, the child's social impairment severity was found to predict parenting-specific stress.

CONCLUSION

This study highlights the pervasive influence of ASD symptomatology on the mental wellbeing of the parents and the importance of assisting parents to cope with the behavioural and social impairments of their child.

Parental and professional beliefs on the treatment and management of ADHD

OBJECTIVE

This study examined parental and professional beliefs about the efficacy of various treatment strategies for ADHD.

METHOD

Parents of children with and without ADHD and seven medical and nonmedical professional groups (N = 673) completed a questionnaire examining their beliefs about the efficacy of various treatment regimes.

RESULTS

Principle component analysis identified four factors-school-based interventions, medical and allied health interventions, parent interventions, and nontraditional interventions. Although there were some group differences in the level of endorsement for these factors, there was a high degree of concordance between the groups. The school-based interventions factor was the most highly endorsed, whereas the nontraditional interventions factor was the least endorsed by the sample as a whole.

CONCLUSION

The results suggest that the low level of interdisciplinary interaction that has been reported in the literature is not due to differences in beliefs about the efficacy of various treatment strategies for ADHD.

The Effects of Diagnostic Labelling on the Implicit Theories of Attention-Deficit/Hyperactivity Disorder Held by Health Professionals

Attention-deficit/hyperactivity disorder (ADHD) is the most recent diagnostic label used to describe a behavioural condition of which the essential features are developmentally inappropriate levels of inattention, impulsivity and overactivity. ADHD has attracted both controversy and attention from the professional and scientific community. However, little is known regarding the explanatory models (implicit theories) of health professionals or of their beliefs regarding the treatment of this condition, specifically the impact of diagnostic labelling on their decisions concerning treatment. This study manipulated the presence versus absence of the diagnostic label ‘ADHD’ in a vignette study describing the symptoms of this condition. The vignette was presented to professionals in the educational, mental health and allied health fields. After reading the vignette, participants were required to complete a questionnaire examining implicit beliefs concerning ADHD. The results confirmed that the presence of the diagnostic label (ADHD) changed the causal explanations by professional groups. However, the presence of the diagnostic label did not significantly change the beliefs about the optimal treatment strategy for this condition.

The balance model of dyslexia and remedial training: an evaluative study

The aim of this study was to test the validity of Bakker's (1983, 1990) theory and treatment paradigm of dyslexia. Twenty-one children (mean age = 9.9 years) categorized as P-type dyslexics (showing accurate but slow and fragmented reading) and 19 children (mean age = 9.7 years) categorized as L-type dyslexics (fast but inaccurate readers) were presented with hemisphere-specific stimulation (HSS) and hemisphere-alluding stimulation (HAS). HSS was produced by presenting words to either the left or the right visual half-field, or to the left or right hand of the participant. HAS training was achieved through the presentation of either semantically/phonetically demanding or perceptually demanding text. Participants were given either a treatment program that was specifically designed for their particular dyslexia subtype, or a program that had been deliberately chosen to be inconsistent with their subtype. Contrary to predictions, participants made gains on all of the reading measures, regardless of the type of treatment given. On the basis of these findings it is suggested that treatment gains made are due to nonspecific training effects and not to the specific nature of Bakker's remedial strategies.

S-acetonyl-CoA. A nonreactive analog of acetyl-CoA

We have synthesized S-acetonyl-CoA from CoASH and 1-bromoacetone. This thioether-containing structural analogue of acetyl-CoA is a potent competitive inhibitor, with respect to acetyl-CoA, of citrate synthase, phosphotransacetylase, and carnitine acetyltransferase. This analog will not activate Escherichia coli phosphoenolpyruvate carboxylase or rat liver pyruvate carboxylase, two enzymes which require acetyl-CoA as an obligate activator. Furthermore, acetonyl-CoA will not compete with acetyl-CoA for binding to these enzymes showing the apparent absolute requirement of these two enzymes for a thioester group on the activating ligand. S-Acetonyl-CoA should be a useful reagent in the investigation of acetyl-CoA-requiring processes.
