Cognitive benefits of right-handedness: a meta-analysis.

Hand preference - which is related to cerebral dominance - is thought to be associated with cognitive skills; however, findings on this association are inconsistent and there is no consensus whether left- or right-handers have an advantage in either spatial or verbal abilities. In addition, it is not clear whether an interaction between sex and hand preference exists in relation to these cognitive abilities. As these matters are relevant from a neurodevelopmental perspective we performed a meta-analysis of the available literature. We searched PubMed and Embase, and included 14 studies (359,890 subjects) in the verbal ability meta-analysis and 16 studies (218,351 subjects) in the spatial ability meta-analysis. There was no difference between the full sample of left and right-handers for verbal ability, nor was there a hand preference-by-sex interaction. Subgroup analysis of children showed a small right-hand benefit. Our results further revealed a modest but significant effect favouring right-handedness for overall spatial ability, which was more pronounced when analysis was restricted to studies applying the mental rotation test. We could not identify a specific interaction with sex. Our results indicate that there is a small but significant cognitive advantage of right-handedness on spatial ability. In the verbal domain, this advantage is only significant in children. An interaction effect with sex is not confirmed.

Supported decision-making for persons with mental illness: a review.

Persons with mental illness (PWMI) are often not afforded the same opportunity to make decisions on a par with others in society. Article 12 of the International Convention on the Rights of Persons with Disabilities (CRPD) states that persons with disabilities should have equal recognition before the law and the right to exercise their legal capacity. Exercising legal capacity can mean making decisions about employment, medical or psychosocial treatment, property, finances, family, and participation in community activities. The aim of this paper is to comprehensively review the evidence on supported decision making for PWMI, both in legislation and research globally, with a focus on low- and middle-income countries (LMICs). Results reveal only a few countries have provisions for supported decision-making for PWMI, with a particular shortage of such provisions in legislation in LMICs There is also a general paucity of research evidence for supported decision-making, with the majority of research focusing on shared decision-making for treatment decisions. This review highlights the need for additional research in this area to better guide models, which can be utilised in domestic legislation, particularly in LMICs, to better implement the ideals of Article 12 of the CRPD.

Impact of Birth Preparedness and Complication Readiness Interventions on Birth with a Skilled Attendant: A Systematic Review

Background Increased preparedness for birth and complications is an essential part of antenatal care and has the potential to increase birth with a skilled attendant. We conducted a systematic review of studies to assess the effect of birth preparedness and complication readiness interventions on increasing birth with a skilled attendant. Methods PubMed, Embase, CINAHL and grey literature were searched for studies from 2000 to 2012 using a broad range of search terms. Studies were included with diverse designs and intervention strategies that contained an element of birth preparedness and complication readiness. Data extracted included population, setting, study design, outcomes, intervention description, type of intervention strategy and funding sources. Quality of the studies was assessed. The studies varied in BP/CR interventions, design, use of control groups, data collection methods, and outcome measures. We therefore deemed meta-analysis was not appropriate and conducted a narrative synthesis of the findings. Results Thirty-three references encompassing 20 different intervention programmes were included, of which one programmatic element was birth preparedness and complication readiness. Implementation strategies were diverse and included facility-, community-, or home-based services. Thirteen studies resulted in an increase in birth with a skilled attendant or facility birth. The majority of authors reported an increase in knowledge on birth preparedness and complication readiness. Conclusions Birth Preparedness and Complication Readiness interventions can increase knowledge of preparations for birth and complications; however this does not always correspond to an increase in the use of a skilled attendant at birth.

A Review of Barriers to Using Psychiatric Advance Directives in Clinical Practice

Despite advocacy and demand for psychiatric advance directives (PADs), uptake and implementation in clinical practice is low. We examine why PAD implementation has been difficult globally by reviewing barriers in existing evidence. The review includes 30 studies, and identified 13 barriers, clustered into system level barriers, health professional level barriers, and service user level barriers. The considerable barriers to uptake and implementation hamper PAD use. We propose several potential strategies for overcoming some of the barriers. In order to realise these strategies, additional research is needed, particularly more field-based and operational research to understand processes and difficulties experienced in clinical practice.

A protocol for a systematic review of birth preparedness and complication readiness programs

BackgroundOne of the effective strategies for reducing the number of maternal deaths is delivery by a skilled birth attendant. Low utilization of skilled birth attendants has been attributed to delay in seeking care, delay in reaching a health facility and delay in receiving adequate care. Health workers could play a role in helping women prepare for birth and anticipate complications, in order to reduce delays. There is little evidence to support these birth preparedness and complication readiness (BP/CR) programs; however, BP/CR programs are frequently implemented. The objective of this review is to assess the effect of BP/CR programs on increasing skilled birth attendance in low-resource settings.MethodsDue to the complexity of BP/CR programs and the need to understand why certain programs are more effective than others, we will combine both quantitative and qualitative studies in this systematic review. Search terms were selected with the assistance of a health information specialist. Three reviewers will independently select and assess studies for quality. Data will be extracted by one reviewer and checked for accuracy and completeness by a second reviewer. Discussion between the reviewers will resolve disagreements. If disagreements remain, a third party will be consulted. Data analysis will be carried out in accordance with the BP/CR matrix, developed by the Johns Hopkins Program for International Education in Gynecology and Obstetrics (JHPIEGO). Study data will be grouped and analyzed by quality and study design and regrouped according to type of intervention strategy.DiscussionThis review will provide: 1) an insight into existing BP/CR programs, 2) recommendations on effective elements of the different approaches, 3) proposals for concrete action plans for health professionals in the field of reproductive health in resource-poor settings and 4) an overview of existing knowledge gaps requiring further research.Systematic review registrationPROSPERO registration no.: CRD42012003124

Unpacking the psychiatric advance directive in low-resource settings: an exploratory qualitative study in Tamil Nadu, India

BackgroundPsychiatric advance directives, a tool to document preferences for care in advance of decisional incapacity, have been shown to benefit persons with mental illness in a number of countries through improving medication adherence, reducing symptoms from escalating in a crisis, accelerating recovery, and enhancing service user autonomy. While concepts such as autonomy are important in a number of high-income country settings, it remains unclear whether tools like psychiatric advance directives are suitable in a different context. The recent introduction of the psychiatric advance directive into draft legislation in India prompts the question as to how feasible psychiatric advance directives are in the Indian context. The aim of this study is to explore the feasibility and utility of PADs in India, with a focus on the need for individual control over decision making and barriers to implementation, by exploring views of its central stakeholders, service users and carers.MethodsQualitative semi-structured interviews (n = 51) with clients (n = 39) and carers (n = 12) seeking mental health treatment at outpatient clinics in urban and rural settings provided by a non-profit organisation in Tamil Nadu, India.ResultsClients engaged in a number of forms of decision-making (passive, active, and collaborative) depending on the situation and decision at hand, and had high levels of self-efficacy. Most clients and carers were unfamiliar with PADs, and while some clients felt it is important to have a say in treatment wishes, carers expressed concerns about service user capacity to make decisions. After completing PADs, clients reported an increase in self-efficacy and an increased desire to make decisions.ConclusionsThe introduction of psychiatric advance directives in India appears to be associated with positive outcomes for some service users, however, there is a need to better understand how this tool can be adapted to better suit the care context in India and hold meaning and value for service users to complete.

What do service users want? A content analysis of what users may write in psychiatric advance directives in India

Although psychiatric advance directives give service users control over their care, very few studies exist on the content of PADs. This paper aims to contribute to this evidence base by presenting the content of psychiatric advance directives in India. Participants were 75 clients seeking outpatient care at a mental health services organisation in Tamil Nadu, India, who agreed to draft a PAD. Most clients were comfortable with appointing a representative (usually a family member) to make decisions on their behalf during a period of decisional incapacity or relapse, were willing to accept admission to the hospital/clinic and take medication if required, wanted to have a trusted person to discuss their mental health problems. No client used the opportunity to outright refuse treatment. This study highlights an important first step in improving the quality of mental health care by documenting user preferences for care in India. More in-depth research is needed to elicit rich descriptions of experiences of care and user-centred understanding of rights.

How can mental health and faith-based practitioners work together? A case study of collaborative mental health in Gujarat, India

Despite the knowledge that people with mental illness often seek care from multiple healing systems, there is limited collaboration between these systems. Greater collaboration with existing community resources could narrow the treatment gap and reduce fragmentation by encouraging more integrated care. This paper explores the origins, use, and outcomes of a collaborative programme between faith-based and allopathic mental health practitioners in India. We conducted 16 interviews with key stakeholders and examined demographic and clinical characteristics of the user population. Consistent with previous research, we found that collaboration is challenging and requires trust, rapport-building, and open dialogue. The collaboration reached a sizeable population, was reviewed favourably by key stakeholders—particularly on health improvement and livelihood restoration—and perhaps most importantly, views the client holistically, allowing for both belief systems to play a shared role in care and recovery. Results support the idea that, despite differing practices, collaboration between faith-based and allopathic mental health practitioners can be achieved and can benefit clients with otherwise limited access to mental health care.
