Childhood bullying is a public health priority. We evaluated the effectiveness and costs of KiVa, a whole-school anti-bullying program that targets the peer context.

A two-arm pragmatic multicenter cluster randomized controlled trial with embedded economic evaluation. Schools were randomized to KiVa-intervention or usual practice (UP), stratified on school size and Free School Meals eligibility. KiVa was delivered by trained teachers across one school year. Follow-up was at 12 months post randomization. Primary outcome: student-reported bullying-victimization; secondary outcomes: self-reported bullying-perpetration, participant roles in bullying, empathy and teacher-reported Strengths and Difficulties Questionnaire. Outcomes were analyzed using multilevel linear and logistic regression models.

Between 8/11/2019–12/02/2021, 118 primary schools were recruited in four trial sites, 11 111 students in primary analysis (KiVa-intervention: n = 5944; 49.6% female; UP: n = 5167, 49.0% female). At baseline, 21.6% of students reported being bullied in the UP group and 20.3% in the KiVa-intervention group, reducing to 20.7% in the UP group and 17.7% in the KiVa-intervention group at follow-up (odds ratio 0.87; 95% confidence interval 0.78 to 0.97, p value = 0.009). Students in the KiVa group had significantly higher empathy and reduced peer problems. We found no differences in bullying perpetration, school wellbeing, emotional or behavioral problems. A priori subgroup analyses revealed no differences in effectiveness by socioeconomic gradient, or by gender. KiVa costs £20.78 more per pupil than usual practice in the first year, and £1.65 more per pupil in subsequent years.

The KiVa anti-bullying program is effective at reducing bullying victimization with small-moderate effects of public health importance.

Executive and mnemonic impairments have been well documented in the high-risk states for development of psychosis and have been pinpointed as a possible core neuropsychological dysfunction. However, their neurofunctional correlates are still not clear.

fMRI was used in 17 patients at risk for developing psychosis (ARMS, “at risk mental state”), 10 patients with a first episode of psychosis (FEP) and 15 age-matched healthy comparison subjects to examine neural responses to increasing difficulty of mnemonic engagement in an object–location paired associate memory task. Groups were matched in terms of age, IQ, gender, and psychopathology ratings. Accuracy and reaction time were recorded during the scan.

As the mnemonic load increased, response latency increased and response accuracy decreased in an approximately linear fashion. No main effect for group was observed. However, a trend towards decreased accuracy in FEP subjects, as compared with controls, was evident. As the task difficulty increased, increased brain activity was observed in the medial frontal cortex and in the medial posterior parietal cortex. Between-groups differences in activation were observed in a cluster spanning the MFG, SFG and SMA and in the right precuneus. However, these neurofunctional abnormalities were more evident in the most demanding level of the task than in the easy level, with the ARMS groups showing less activation than controls and higher activation than FEP.

Abnormal neural activity in medial frontal cortex and posterior parietal cortex during paired associate learning task may represent a neurofunctional substrates of vulnerability to psychosis.

People with ‘prodromal’ symptoms have a very high risk of developing psychosis. We used functional MRI to examine the neurocognitive basis of this vulnerability.

Cross-sectional comparison of subjects with an ARMS (n=17), first episode schizophreniform psychosis (n=10) and healthy volunteers (n=15). Subjects were studied using functional MRI while they performed an overt verbal fluency task, a random movement generation paradigm and an N-Back working memory task.

During an N-Back task the ARMS group engaged inferior frontal and posterior parietal cortex less than controls but more than the first episode group. During a motor generation task, the ARMS group showed less activation in the left inferior parietal cortex than controls, but greater activation than the first episode group. During verbal fluency using ‘Easy’ letters, the ARMS group demonstrated intermediate activation in the left inferior frontal cortex, with first episode groups showing least, and controls most, activation. When processing ‘Hard’ letters, differential activation was evident in two left inferior frontal regions. In its dorsolateral portion, the ARMS group showed less activation than controls but more than the first episode group, while in the opercular part of the left inferior frontal gyrus / anterior insula activation was greatest in the first episode group, weakest in controls and intermediate in the ARMS group.

The ARMS is associated with abnormalities of regional brain function that are qualitatively similar to those in patients who have just developed psychosis but less severe.

There is increasing evidence that changes in connections linking brain regions, as well as grey matter volumetric abnormalities are important in schizophrenia. The extent to which these are related to being at risk of psychosis as opposed to having a psychotic disorder is unclear. We will review the diffusion tensor imaging (DTI) findings which inform us about white matter integrity and organization, and relate it to our own work which compares grey matter volumes and white matter integrity in people at high risk of psychosis, patients with first episode psychosis, and healthy volunteers. We will also discuss the relationship of these findings to clinical symptoms and outcome.

30 subjects with an ‘at risk mental state’ (PACE criteria), 15 first psychotic episode patients and 30 controls were studied using an SPGR sequence and DTI.

Both the volumetric and DTI datasets were analysed using voxel based techniques in standard space. There were frontal and temporal grey matter reductions in the first episode group and more modest temporo-parietal volume reductions in the ‘at risk’ group. The first episode group had reduced fractional anisotropy in the superior longitudinal fasciculus bilaterally, left anterior corpus callosal and right superior fronto-occiptal tracts relative to controls, with qualitatively similar but less severe reductions in the ‘at risk’ subjects.

Abnormalities in the frontal and temporal grey matter and the tracts connecting them were evident in patients with first episode schizophrenia, with similar but less marked abnormalities in subjects with an ‘at risk’ mental state.

While recent research points to the potential benefits of clinical intervention before the first episode of psychosis, the logistical feasibility of this is unclear.

To assess the feasibility of providing a clinical service for people with prodromal symptoms in an inner city area where engagement with mental health services is generally poor.

Following a period of liaison with local agencies to promote the service, referrals were assessed and managed in a primary care setting. Activity of the service was audited over 30 months.

People with prodromal symptoms were referred by a range of community agencies and seen at their local primary care physician practice. Over 30 months, 180 clients were referred; 58 (32.2%) met criteria for an at risk mental state, most of whom (67.2%) had attenuated psychotic symptoms. Almost 30% were excluded due to current or previous psychotic illness, of which two-thirds were in the first episode of psychosis. The socio-demographic composition of the 'at risk' group reflected that of the local population, with an over-representation of clients from an ethnic minority. Over 90% of suitable clients remained engaged with the service after 1 year.

It is feasible to provide a clinical service for people with prodromal symptoms in a deprived inner city area with a large ethnic minority population.

Experiences of bereavement can be stressful and are frequently complicated by emotional, familial, and financial issues. Some—though not all—caregivers may benefit from bereavement support. While considered standard within palliative care services in Australia, bereavement support is not widely utilized by family caregivers. There is little research focused on the forms of bereavement support desired or required by family caregivers, how such care is viewed, and/or how bereavement support is experienced. This study examined the experiences of bereaved family caregivers and their impressions of and interactions with bereavement support.

This paper reports on one aspect of a broader study designed to explore a range of experiences of patients and caregivers to and through palliative care. Focusing on experiences of bereavement, it draws on qualitative semistructured interviews with 15 family caregivers of palliative care patients within a specialist palliative care unit of an Australian metropolitan hospital. The interviews for this stage of the study were initiated 3–9 months after an initial interview with a family caregiver, during which time the palliative patient had died, and they covered family caregivers' experiences of bereavement and bereavement support. Interviews were digitally audiotaped and transcribed in full. A thematic analysis was conducted utilizing the framework approach wherein interview transcripts were reviewed, key themes identified, and explanations developed.

The research identified four prevalent themes: (1) sociocultural constructions of bereavement support as for the incapable or socially isolated; (2) perceptions of bereavement support services as narrow in scope; (3) the “personal” character of bereavement and subsequent incompatibility with formalized support, and (4) issues around the timing and style of approaches to being offered support.

Systematic pre-bereavement planning and careful communication about the services offered by palliative care bereavement support centers may improve receipt of support among bereaved family caregivers in need.
