The impact of public transport on the health of work commuters: a systematic review.

Although the public transport (PT) commute can form a substantial part of the working day, there is a significant gap in our understanding of how it influences health of those who engage in it. The purpose of this systematic review was to therefore generate evidence from 1972 about the extent to which the PT commute (involving train, bus, subway, tram, or metro) impacts on the mental health, physical health and well-being of the working people. We identified 47 studies in English worldwide involving an empirical quantitative focus which met the inclusion criteria. Of these, 23 studies involved over 500 participants. Although initial multi-modal comparisons showed impact on sickness rate, self-rated health complaints, perceived stress level and reduction in sleep, a more homogeneous analysis of rail commuters showed elevation in salivary cortisol, perceived stress, and affective reactions to crowding. Findings also revealed a bias towards use of endogenous self-report measures. On this basis, we argue that it would be of benefit to test theoretical models to account for more objective measures of job and commuting stress. Recommendations were made for flexible working agendas.

Neurodevelopmental outcomes in individuals with fetal alcohol spectrum disorder (FASD) with and without exposure to neglect: Clinical cohort data from a national FASD diagnostic clinic.

Disentangling the relative developmental impact of prenatal alcohol exposure from postnatal neglect is clinically valuable for informing future service provision. In this study, developmental outcomes across groups are compared in a 'natural experiment'. METHODS: Clinical data from 99 persons with fetal alcohol spectrum disorder (FASD) diagnoses were audited. Developmental outcomes (diagnosis of attention deficit hyperactivity disorder, ADHD; social and communication disorder, SCD; or Autistic Spectrum Disorder, ASD; Short Sensory Profile, SSP; Vineland II Adaptive Behaviour Scales) were compared across two exposure groups: prenatal alcohol only; and mixed prenatal alcohol and neglect. RESULTS: ADHD (74%) and ASD/SCD (68%) were common, with no significant difference between groups (ADHD, p = 0.924; ASD, p = 0.742). Vineland age equivalence scores were lower than chronological age (11.1 years - prenatal alcohol only, and 12.7 years - neglect) across all domains, especially receptive language (3.7 years for both groups). Age equivalence did not differ between groups, with the exception of domestic daily living (neglect: 7.7 years vs. prenatal alcohol only: 5.8 years, p = 0.027). A probable/definite difference on SSP was more common in the prenatal alcohol only (96% vs. 67%, p = 0.006). For the individual subscales of SSP, there were no significant differences by neglect category. DISCUSSION: Postnatal neglect in this group did not make the developmental outcome any worse, suggesting that prenatal alcohol influences these outcomes independently. Professionals who support families looking after a child with both FASD and a history of neglect should be aware that the behavioral difficulties are likely to be related to prenatal alcohol exposure and not necessarily reflective of parenting quality.

What can be done to lessen morbidity associated with fetal alcohol spectrum disorders?

Fetal alcohol syndrome and its wider spectrum of presentation fetal alcohol spectrum disorders represent a range of disorders that are sometimes difficult to recognise as they may present in a way that overlaps with other conditions. This makes identification and recognition challenging, which increases the burden associated with the disorder. When considering the reduction in morbidity, both prevention of exposure to alcohol by the fetus and early identification of cases are required. This selective review seeks to highlight some of the complexities involved as well as highlighting the challenges. By considering populations particularly at risk to exploring the reality of alcohol risk it will seek to offer some solutions to begin the process of change.

Does IQ Really Predict Job Performance?

IQ has played a prominent part in developmental and adult psychology for decades. In the absence of a clear theoretical model of internal cognitive functions, however, construct validity for IQ tests has always been difficult to establish. Test validity, therefore, has always been indirect, by correlating individual differences in test scores with what are assumed to be other criteria of intelligence. Job performance has, for several reasons, been one such criterion. Correlations of around 0.5 have been regularly cited as evidence of test validity, and as justification for the use of the tests in developmental studies, in educational and occupational selection and in research programs on sources of individual differences. Here, those correlations are examined together with the quality of the original data and the many corrections needed to arrive at them. It is concluded that considerable caution needs to be exercised in citing such correlations for test validation purposes.

Walking school buses as a form of active transportation for children-a review of the evidence.

BACKGROUND: Walking school buses (WSBs) offer a potentially healthier way for children to get to school while reducing traffic congestion. A number of pressing societal challenges make it timely to evaluate evidence of their value. METHODS: Studies that focused solely on WSBs were identified through online and manual literature searches. Twelve WSB studies involving a total of 9169 children were reviewed. Study aims, designs, methods, outcomes, and barriers and facilitators were examined. RESULTS: WSBs were found to be associated with increased prevalence of walking to school and general activity levels although not always significantly. Time constraints emerged as barriers to WSBs, impacting on recruitment of volunteers and children to the WSBs. Facilitators of WSBs included children enjoying socializing and interacting with the environment. CONCLUSIONS: Preliminary evidence of the health value of WSBs was demonstrated, along with recommendations for the design of future studies. By tackling barriers of time constraints, volunteer recruitment, and parents' safety concerns while at the same time, increasing convenience and time savings for families, future WSBs are likely to be more sustainable and taken up by more schools. Implications for future innovation in school health were identified.

The missing dimension: the relevance of people's conception of time.

While a timely conceptual innovation for the digital age, the "map" proposed by Bentley et al. would benefit from strengthening through the inclusion of a non-clock-time perspective. In this way, there could be new hypotheses developed which could be applied and tested relevant to more diverse societies, cultures, and individuals.

Children's memories for events relating to treatment for eye cancer: Influence of age at loss of eye.

Treatment for retinoblastoma frequently involves removal of at least one eye in the first 5 years. Variation in age of treatment leads to the assumption that children's later verbal accessibility of early traumatic memories may vary, with some children having less opportunity to make sense of their condition. Video recordings were made of 17 children who had undergone enucleation either before 24 months (n = 8) or after 24 months (n = 9) involved in "hospital play'' using props designed to elicit talk about "eyes." The hypothesis that a larger number of verbalizations about medical procedures would occur in children enucleated after 24 months than before 24 months was supported. Children enucleated after 24 months engaged in significantly more talk about enucleation and/or examination under anesthetic whereas none of the children enucleated in infancy talked about these medical events. The outcome supports the view that there is a transition around 24 months in the extent to which children can have verbal access to previous traumatic memories. The design of interventions needs to take into account that children enucleated in infancy have less opportunity for later verbal access to early memories of traumatic events than those treated later, leading to possible misconceptions about their own condition.
