Common psychology problems in cerebral palsy

Cerebral palsy (CP) refers to a collection of motor impairments which result in abnormal posture and movement following an insult or damage to the developing brain. Psychological adjustment in children with CP is under researched with little population-based or longitudinal data, but there is sufficient evidence to suggest that children with CP are at increased risk for psychological problems. The types of difficulties they experience include emotional, hyperactivity and peer problems with conduct disorder being more prevalent in mildly affected children. The origins of psychological problems in this group are complex but include ‘disease’ and ‘psychosocial’ factors related to having a brain-based disability in the family, as well as other factors that influence adjustment in all children. There are no intervention studies in children with CP aimed at preventing psychological problems or promoting mental wellbeing. However, evidence from other work suggests it is possible to work with the child and family to develop skills, manage symptoms, and build confidence and resilience. Acting as early as possible has been found to be beneficial for bonding, child development and reducing parental anxiety.

Child abuse as a complex and wicked problem: Reflecting on policy developments in the United Kingdom in working with children and families with multiple problems

In spite of significant public concern, professional efforts and financial expenditure, there has been a perceived lack of progress in reducing the incidence of child abuse, and in improving the outcomes for children in both the short and longer term. In this article the authors reflect on recent policy developments in the United Kingdom relating to children and families experiencing multiple adversities, and argue that the current conceptualisation of child abuse is flawed. In adopting a rational technical approach to the management of child abuse, there is a tendency to focus on shorter term outcomes for the child, such as immediate safety, that primarily reflect the outputs of the child protection system. However, by viewing child abuse as a wicked problem, that is complex and less amenable to being solved, then child welfare professionals can be supported to focus on achieving longer term outcomes for children that are more likely to meet their needs. The authors argue for an earlier identification of and intervention with children who are experiencing multiple adversity, such as those living with parents misusing substances and exposed to intimate partner violence.

Adaptive automated construction of hybrid heuristics for exam timetabling and graph colouring problems

In this paper, we present a random iterative graph based hyper-heuristic to produce a collection of heuristic sequences to construct solutions of different quality. These heuristic sequences can be seen as dynamic hybridisations of different graph colouring heuristics that construct solutions step by step. Based on these sequences, we statistically analyse the way in which graph colouring heuristics are automatically hybridised. This, to our knowledge, represents a new direction in hyper-heuristic research. It is observed that spending the search effort on hybridising Largest Weighted Degree with Saturation Degree at the early stage of solution construction tends to generate high quality solutions. Based on these observations, an iterative hybrid approach is developed to adaptively hybridise these two graph colouring heuristics at different stages of solution construction. The overall aim here is to automate the heuristic design process, which draws upon an emerging research theme on developing computer methods to design and adapt heuristics automatically. Experimental results on benchmark exam timetabling and graph colouring problems demonstrate the effectiveness and generality of this adaptive hybrid approach compared with previous methods on automatically generating and adapting heuristics. Indeed, we also show that the approach is competitive with the state of the art human produced methods.

“If I’m brutally honest research has never appealed to me …”: The Problems and Successes of a Peer Research Project

This paper describes the use of a peer research methodology to explore disaffected young people’s views on alternative education. This model was adopted in order to try to ensure an equilibrium of power between interviewer and interviewee, allow marginalised young people’s voices to be heard and help generate social action. The approach is examined from the perspective of both the peer research and adult research teams. An experiential and honest account is given including the problems and successes, as well as the lessons learned. The paper concludes by considering the value of the model, whether it helps to reach those alienated from education and any evidence that it provides an opportunity for them to have a stake in their future.

Convergence acceleration of the doubly periodic Green's function for the analysis of thin wire arrays

A method is proposed to accelerate the evaluation of the Green's function of an infinite double periodic array of thin wire antennas. The method is based on the expansion of the Green's function into series corresponding to the propagating and evanescent waves and the use of Poisson and Kummer transformations enhanced with the analytic summation of the slowly convergent asymptotic terms. Unlike existing techniques the procedure reported here provides uniform convergence regardless of the geometrical parameters of the problem or plane wave excitation wavelength. In addition, it is numerically stable and does not require numerical integration or internal tuning parameters, since all necessary series are directly calculated in terms of analytical functions. This means that for nonlinear problem scenarios that the algorithm can be deployed without run time intervention or recursive adjustment within a harmonic balance engine. Numerical examples are provided to illustrate the efficiency and accuracy of the developed approach as compared with the Ewald method for which these classes of problems requires run time splitting parameter adaptation.

Psychological problems in children with hemiplegia: a European multicentre survey

Objective: To describe the prevalence and determinants of psychological problems in European children with hemiplegia. Design: Cross-sectional survey. Setting: Home visits in nine European regions by research associates who administered standard questionnaires to parents. Patients: 279 children with hemiplegia aged 8–12 years were recruited from population-based case registers. Outcome measure: Strengths and Difficulties Questionnaire comprising emotion, conduct, hyperactivity, peer problems and prosocial domains. An “impact score” (IS) measures the social and psychological impact of the child’s difficulties. Results: Children with hemiplegia had higher mean scores on the total difficulties score (TDS) compared with a normative sample (p<0.001). 48% and 57% of children, respectively, had borderline–abnormal TDS and IS. Significant, independent associations were observed between intellectual impairment and an increased risk for hyperactivity (odds ratio; OR 8.4, 95% CI 3.4 to 20.8), peer problems (OR 3.1, 95% CI 1.7 to 5.5), psychological and social impact (OR 3.0, 95% CI 1.6 to 5.6) when children with an intellectual quotient (IQ) <50 were compared with those with an IQ >70. Boys had an increased risk for conduct (OR 2.1, 95% CI 1.2 to 3.7) and hyperactivity disorders (OR 2.5, 95% CI 1.4 to 4.6). Poor self-esteem was associated with an increased risk for peer problems (OR 5.8, 95% CI 2.5 to 13.4) and poor prosocial skills (OR 7.5, 95% CI 2.4 to 23.2) compared with those with high self-esteem. Other determinants of psychological adjustment were impaired communication, severe pain and living with a single parent. Conclusions: Many of the psychological problems identified are amenable to treatment. Special attention should be given to those at highest risk of developing psychological difficulties.

A Longitudinal Study of the Effects of Childhood Trauma on Symptoms and Functioning of People with Severe Mental Health Problems

This study examines the relationship between childhood trauma and the psychiatric symptoms and psychosocial functioning of adults with severe mental health problems. Participants (n = 31) were recruited from the caseloads of community mental health services in Northern Ireland and assessed at baseline, 9 months, and 18 months. More than half had a history of childhood trauma (n = 17). There were no differences between the no childhood trauma (n = 14) and childhood trauma groups on psychiatric symptoms, but a significant relationship was found between trauma history and all aspects of social functioning. Those with no history of trauma showed improved psychosocial functioning over time, whereas those with a history of trauma deteriorated. These findings have implications for current service provision.
