Predictors of non-return to work 2 years post-injury in road traffic crash survivors: results from the UQ SuPPORT study

Individuals who have sustained an injury from a road traffic crash (RTC) are at increased risk for long lasting health problems and non-return to work (NRTW). Determining the predictors of NRTW is necessary to develop screening tools to identify at-risk individuals and to provide early targeted intervention for successful return to work (RTW). The aim of this study was to identify factors that can predict which individuals will not RTW following minor or moderate injuries sustained from a RTC.Participants were 194 claimants (63.4% female) within a common-law "fault-based" system from the UQ SuPPORT cohort who were working prior to their RTC. Participants were assessed at 6 months on a variety of physical and mental health measures and RTW status was determined at 2 years post-RTC. RTW rate was 78.4%.Univariate predictors of NRTW included being the driver or passenger, having a prior psychiatric diagnosis, high disability level, low mental or physical quality of life, predicted non-recovery, high pain, low function, high expectations of pain persistency, low expectations about RTW, having a psychiatric diagnosis, elevated depression or anxiety. The final multivariable logistic regression model included only two variables: disability level and expectations about RTW. Seventy-five percent of individuals who will not RTW by 2 years can be identified accurately at an early stage, using only these two predictors.The results are promising, because they suggest that having information about two factors, which are easily obtainable, can predict with accuracy those who will require additional support to facilitate RTW

Recovery trajectories for long-term health-related quality of life following a road traffic crash injury: results from the UQ SuPPORT study

Background Diminished physical and mental health-related quality of life (HRQoL) is a common consequence of road traffic crash (RTC) injury. This study aimed to (a) determine the probable recovery trajectories in physical and mental HRQoL; (b) examine the impact of posttraumatic stress disorder (PTSD) on HRQoL scores within these trajectory groups; and (c) examine the influence of predictor covariates on trajectory group membership. Methods 336 (63% female, M =44.72; SD =14.77) injured RTC survivors completed the SF-36v2 at approximately 6, 12, and 24 months after sustaining a RTC injury. Participants also completed telephone interviews to assess prior history of psychological disorder and current PTSD at each wave. Results Three trajectories were identified for SF-36v2 Physical Component Score (PCS): ”gradual recovery” (27.3%);”low but improving” (54.7%); and”severe and chronic” (17.9%). Four trajectories were defined for SF36v2 Mental Component Score (MCS): “unaffected” (19.1%);”severe but improving” (24.1%);”severe and declining” (17.3%); and”low but improving” (39.5%). A PTSD diagnosis significantly reduced SF36v2 component scores only in trajectories associated with poorer outcome. Age was predictive of trajectory group membership for PCS, whereas injury severity was predictive of trajectory group membership for MCS. Limitations Use of a compensation seeking sample affects generalizability to the general RTC population. Conclusions This study identified a concerning subgroup of individuals who have chronic and/or declining physical and mental HRQoL that can be impacted by a diagnosis of PTSD. The development of interventions with a special focus on associated psychological injury is needed to improve the HRQoL of at-risk individuals following RTC injury

Stage 1 Registered Report: The relationship between handedness and language ability in children [version 1; referees: 2 approved]

Weak or inconsistent hand preference may be a risk factor for developmental language delay.  This study will test the extent to which variations in language skills are associated with the strength of hand preference. Data are drawn from a large sample (n = 569) of 6- to 7-year-old children unselected for ability, assessed at two time points, 6 months apart. Hand preference is assessed using the Quantitative Hand Preference task (QHP) and five uni-manual motor tasks. Language skills (expressive and receptive vocabulary, receptive grammar, and morphological awareness) are assessed with standardized measures. If weak cerebral lateralisation (as assessed by the QHP task) is a risk factor for language difficulties, it should be possible to detect such effects in the large representative sample of children examined here

Changing patterns in the prevalence of posttraumatic stress disorder, major depressive episode and generalized anxiety disorder over 24 months following a road traffic crash: results from the UQ SuPPORT study

Objective: To examine the prevalence and changing patterns of PTSD, major depressive episode (MDE), and generalized anxiety disorder (GAD) in adult claimants who sustained a non-catastrophic injury in a road traffic crash (RTC) in Queensland, Australia. Method: Participants (N = 284) were assessed at approximately 6, 12, and 24 months post-RTC using the composite international diagnostic interview (CIDI) modules for PTSD, and CIDI-short form for MDE, and GAD. Results: The prevalence of at least one of these disorders was 48.2%, 52.5%, and 49.3%, at 6, 12, and 24 months, respectively. Comorbidity was common (20.8% at 6 months, 27.1% at 12 months, and 21.1% at 24 months) and only 33.1% of participants never met PTSD, GAD, or MDE criteria. A substantial proportion of participants (42.3%) had an unstable diagnostic pattern over time. Participants with multiple diagnoses at 6 months were more likely to continue to meet diagnostic criteria for any disorder at 12 and 24 months than participants with a single diagnosis. Participants with PTSD (with or without MDE/GAD) were more likely to meet criteria for any disorder at 24 months than participants with another diagnosis. Preinjury psychiatric history increased the likelihood of any disorder at 24 months post-injury, but did not significantly increase the likelihood of PTSD. Conclusions: People injured in a RTC are at risk of having complex psychological presentations over time. Interventions to prevent mental disorders, especially PTSD, in the early post-injury period are needed to prevent chronic psychological injury, including consideration of comorbidity and dynamic course

When do infants expect hands to be connected to a person?

A violation-of-expectation paradigm was used to test whether infants infer a person based on the presence of hands alone. Infants were familiarized to a pair of hands that extended out from a curtain to play with a rattle, after which the curtain was opened to reveal either a real person or a mannequin. Infants' looking at these outcomes was compared with baseline looking at the person and the mannequin. Experiment 1 showed that 9-month-olds looked significantly longer at the mannequin than at the person after familiarization to hands. Experiment 2 ruled out a low-level feature matching interpretation by showing the same looking pattern in 9-month-olds even when the hands were covered with silver gloves. In Experiment 3, 6-month-olds showed no differential looking at the mannequin and person after familiarization to hands. Taken together, these experiments suggest that infants acquire the expectation that hands are connected to a person between 6 and 9. months of age. This finding has implications for how infants' attribute goals to manual actions

Evaluation of mental health professionals’ views of a higher education scholarship scheme designed to enhance workforce development

Purpose The purpose of this paper is to evaluate the use of a scholarship scheme to support mental health workforce development. Design/methodology/approach Nursing and allied health recipients (n = 72) of a scholarship for postgraduate mental health study provided quantitative and qualitative feedback via an online survey. Findings Benefits of the scholarship scheme include helping to overcome financial barriers to accessing higher education, increased motivation to study, increased knowledge and skills and enhanced positive feelings towards the recipient’s organisation. A total of 44% of participants reported being majorly or completely influenced to remain working in the organisation due to provision of the scholarship. Originality/value This study asks recipients to evaluate the scholarship scheme rather than the associated postgraduate education and provides preliminary support that scholarships are beneficial even when the amount of funding is less than half of course fees and the support from the employer is primarily monetary. The provision of scholarship funding can encourage existing professionals to undertake postgraduate study and attract them to pursue mental health specialisation instead of other health specialisations. Provision of scholarships is one strategy which can positively impact on mental health workforce retention in allied health professionals

Reality check: prior exposure facilitates picture book imitation by 15-month-old infants

We examined whether 15-month-olds could imitate a novel action sequence from a picture book, and whether or not pre-exposure to the objects before reading the book would facilitate imitation. We found that infants only imitated from a picture book above baseline when they had previously interacted with the objects

Developing expertise in human body perception

Adults see the human body shape in all manner of stimuli, including highly abstract stick figures that barely specify the human body configuration and point-light displays (PLDs) that specify only the characteristic motion patterns of the human form. This capacity to quickly and effortlessly perceive the human form reflects our expertise at visually processing human bodies. In this chapter we will argue that expertise in perceiving bodies occurs by virtue of their ubiquity and social significance, not because of any kind of innate representation or privileged learning mechanism. We are claiming this because it is initially stimulus-dependent becoming more and more generalisable over time in a typical learning trajectory

Experience prevents the emergence of the other race effect during infancy

Experience plays a crucial role in the development of the face processing system. Six-month-olds discriminate individual faces from their own and other races. By 9 months, this ability to process other-race faces is typically lost, due to minimal experience with other-race faces, and vast exposure to own-race faces. In this study,we demonstrate that exposing Caucasian infants to Chinese faces through a picture book at home from 6 and 9 months allows Caucasian infants to maintain the ability to discriminate Chinese faces at 9 months. Thus, the development of the processing of face race can be modified by training
