Study ObjectivesThe majority of adolescent sleep research has utilized self-reported sleep duration and some have based information on a solitary question. Whilst some have claimed to have validated sleep survey data with objective actigraphy measures in adolescents, the statistical approach applied only demonstrates the strength of the association between subjective and objective sleep duration data and does not reflect if these different methods actually agree.MethodsData were collected as part of the Midlands Adolescents Schools Sleep Education Study (MASSES). Adolescents (n=225) aged 11-13 years provided estimates for weekday, weekend and combined sleep duration based on self-reported survey data, a 7-day sleep diary, and wrist-worn actigraphy.ResultsWe assessed the strength of the relationship as well as agreement levels between subjective and objectively determined sleep duration (weekday, weekend and combined). Subjective diary sleep duration was significantly correlated with actigraphy estimates for weekday and weekend sleep duration r=0.30, p≤0.001 and r=0.31, p≤0.001 respectively. Pitman’s test demonstrated no significant difference in the variance between weekend sleep duration (r=0.09, p=0.16) and combined sleep duration (r=0.12, p=0.08) indicating acceptable agreement between actigraphy and sleep diary sleep duration only. Self-reported sleep duration estimates (weekday, weekend and combined) did not agree with actigraphy determined sleep duration.ConclusionsSleep diaries are a cost-effective alternative to survey/questionnaire data. Self-reported measures of sleep duration in adolescents do not agree with actigraphy measures and should be avoided where possible. Previous adolescent sleep studies that have utilized self-reported survey data may not provide a complete representation of sleep on the outcome measure of interest.

Recent findings from studies of epileptic patients and schizotypes have suggested that disruptions in multi-sensory integration processes may underlie a predisposition to report out-of-body experiences (OBEs: Blanke et al., 2004; Mohr et al., 2006). It has been argued that these disruptions lead to a breakdown in own-body processing and embodiment. Here we present two studies which provide the first investigation of predisposition to OBEs in the normal population as measured primarily by the recently devised Cardiff anomalous perception scale (CAPS; Bell et al., 2006). The Launay-Slade Hallucination scale (LSHS) was also employed to provide a measure of general hallucination proneness. In Study 1, 63 University students participated in the study, 17 of whom (26%) claimed to have experienced at least one OBE in their lifetime. OBEers reported significantly more perceptually anomalies (elevated CAPS scores) but these were primarily associated with specific measures of temporal-lobe instability and body-distortion processing. Study 2 demonstrated that OBEers and those scoring high on measures of temporal-lobe instability/body-distortion processing were significantly impaired, relative to controls, at a task requiring mental own-body transformations (OBTs) (Blanke et al., 2005). These results extend the findings from epileptic patient studies to the psychologically normal population and are consistent with there being a disruption in temporal-lobe and body-based processing underlying OBE-type experiences.

With reports continually demonstrating increased demand and severity of student mental health needs, it is important to gain a fuller understanding of the impact on embedded student counselling services. The aims of this research were to identify (a) service similarities, (b) factors which impact on services, (c) characteristics of service users, and (d) the use of therapeutic technology (e.g. online self-help). An online survey was completed by 113 heads of UK student counselling services across Higher Education (HE), Further Education (FE), and Sixth Form Colleges (SFCs), to capture service data from the academic year 2013/14. Students predominantly received high-intensity support (e.g. counselling) and referrals increased over 3 years. Challenges to embedded counselling services and their implications for development are discussed.

Against a background of huge changes in the world of university and college students since the turn of the millennium, together with a multitude of reports on student mental health/wellbeing, this article argues that the field of student mental health is hampered by the imprecise use of terms, a rush to action by universities in the absence of a robust evidence-base, and a lack of overall coordination and collaboration in the collection and use of data. In response, we argue for clearer and more consistent use of definitions of, as well as differentiations between, student wellbeing and mental health, for a longitudinal approach to the student body that captures their developmental transitions to and through university, and a strategic and systematic approach to the use of bona fide measures in the collection of data on wellbeing and on the process of outcomes in embedded university counselling services. Such a coordinated approach will provide the necessary evidence-base upon which to develop and deliver appropriate support and interventions to underpin and enhance the quality of students' lives and learning while at university or college.

Collectively, the results are consistent with there being an increased degree of background cortical hyperexcitability in the cortices of individuals predisposed to some ABE-type hallucinations, even in the nonclinical population. The present study also establishes the clinical utility of the pattern-glare task for examining signs of aberrant visual connectivity in relation to visual hallucinations.

We present the first study to examine indicators of autonomic arousal associated with shifts in body image and as a function of predisposition to report spontaneous anomalous bodily experiences (ABEs) from nonclinical samples. Participants completed the Temporal-Lobe Experience subscale of the Cardiff Anomalous Perception scale-a measure associated with anomalous experiences resulting from temporal lobe dysfunction (Bell, Halligan, & Ellis, 2006) followed by a rubber-hand illusion experiment. We examined: (a) the time taken to induce the illusion, (b) effects on the tonic skin conductance level, and (c) phasic skin conductance responses in the form of nonspecific skin conductance responses (NS-SCRs) in the period leading up to the declaration of the illusion. The illusion took significantly longer to induce in those reporting high levels of ABEs, relative to those reporting low levels of such experiences. A significant increase in the tonic skin conductance level and the frequency of NS-SCRs occurred in the period leading directly up to the declaration of the illusion. Both measures were significantly increased for those reporting higher-levels of ABEs. The data question generic notions of "weak" body representations subserving increasing malleability in body image. Instead, they lend general support for a "dysconnection" account of anomalous bodily experiences-at least for some nonclinical hallucinators. Theoretical considerations are discussed.
