ABSTRACT

The raison d'être for psychotherapy1. The aim of the study was to address individual suffering and distress. The sustainable development goals address suffering and distress on a global scale in the context of threats to the survival of our communities and planet. OBJECTIVE: We propose scaling up therapeutic principles for collective impact and nurturing therapist commitment beyond the therapy room, to activate and sustain compassion-in-action at the community system level. DESIGN: The SDGs represent the strength of collective human concern and action coming together. At the half-way point, we are falling dangerously short of our targets, requiring an urgent response. The tenet of this paper is that the weakest link in our journey is not technical capability or finances, or even the impact of multiple intersecting crises, but our ability to collaborate for sustained action-it is the human factor-hence, we need a psychologically informed response. METHOD: Notably, least 'visible' is SDG17, the umbrella goal designated means of implementation, through partnership. Partnership has been treated as a transactional element of SDG projects, rather than the vital heartbeat connecting daily actions to the 2030 vision. Partnership is about investing in relationships and a commitment to working together with a common purpose-the bailiwick of psychological therapists. RESULTS: We propose an architecture to support the development of courageous partnerships and compassionate systems. CONCLUSION: Compassion uniquely potentiates global action on wicked problems.

ABSTRACT

In recent years, an increasing trend in mental health research has been to collaborate with non-governmental organizations [NGOs] and their constituents. However, ethical difficulties can arise as a result of such partnerships. Understanding the ethics-related practices of NGOs engaged in mental health research is therefore critical. This study addressed these questions in a Malawian context. The goal of this study was to investigate NGO's ethical practices in relation to mental health research by identifying characteristics that influence ethical practices and investigating staff conceptualization of ethics and mental health. Twenty individuals who work for different local NGOs took part in one-on-one interviews or a workshop about their engagement in diverse research initiatives. They pinpointed the areas that needed improvement, as well as the challenges and chances to create partnerships and increase research capability. The diversity in conceptualizing mental health was a key influence on research practices, with heterogeneity in definitions reflected in the use of cultural, spiritual, behavioural, or medical terms. Notably, there was also a greater emphasis on procedural ethics than ethics-in-practice. Collaboration dynamics and limited staffing capacity were cited as major ethical practice considerations. Each of these elements have an impact on NGOs' ethical behaviour when conducting mental health research. Participants in the study saw engagement with notions of both ethics and mental health as lacking or rudimentary in their institutions and felt that they needed to be improved through capacity building and stronger research involvement.

ABSTRACT

BACKGROUND: The Mental Health Gap Action Programme (mhGAP) supports engagement of non-specialists in mental health services in Low- and Middle-Income countries. Given this aim, assessment of the effectiveness of approaches under its remit is warranted. AIMS: We evaluated mhGAP approaches relating to child and adolescent mental health, focusing on provider / child outcomes, and barriers / facilitators of implementation. METHODS: Thirteen databases were searched for reviews and primary research on mhGAP roll out for child and adolescent mental health. RESULTS: Twelve studies were reviewed. Provider-level outcomes were restricted to knowledge gains, with limited evidence of other effects. Child-level outcomes included improved access to care, enhanced functioning and socio-emotional well-being. Organisational factors, clients and providers? attitudes and expectations, and transcultural considerations were barriers. CONCLUSIONS: Further attention to the practical and methodological aspects of implementation of evaluation may improve the quality of evidence of the effectiveness of approaches under its remit.

ABSTRACT

PROBLEM: Routine administration of the Edinburgh Postnatal Depression Scale (EPDS) is intended to promote early detection and preventative support for those who may be at risk of perinatal depression and anxiety. The cultural suitability of the EPDS has not been validated in the Aboriginal Australian context. BACKGROUND: Marked differences in health outcomes and service access between Australian Aboriginal and non-Aboriginal women and infants continue to exist. AIM: This study aimed to explore the cultural validity of the EPDS through understanding the experiences of Aboriginal women and midwives. METHODS: Qualitative data was drawn from semi-structured interviews/yarns with 13 Perth-based Aboriginal antenatal women and 10 non-Aboriginal midwives. FINDINGS: Utilising a grounded theory approach, thematic analysis of verbatim transcripts revealed that, surprisingly, women expressed generally favourable views of the EPDS, especially when the relationships between women and midwives were focused on. Midwives, however, expressed reservations about administering the EPDS and used the EPDS as a conversation-starter rather than as a standardised, standalone tool. DISCUSSION: In attempt to reconcile conflicting perspectives, analysis of recordings extended to evaluate micro-processes in the interviews. At the process level, it was clear that demand characteristics operated in some interviews, including socially desirable response biases, demand biases and acquiescent response styles. CONCLUSION: This highlights the need for researchers and clinicians to be trained in non-leading interview questioning techniques and in yarning methodology. Researchers and clinicians should also be aware of the cognitive biases and demand characteristics that may influence responding, likely perpetuated by dominant forces of a colonised society.

ABSTRACT

Although it is well established that emotion-focused coping is associated with burnout, the schema therapy model may improve the prediction of who is most vulnerable to using emotion-focused coping and what kinds of emotion-focused coping carry the greatest risk of burnout. It is also unknown the extent to which resilience might buffer against maladaptive coping in protecting against burnout. The present study investigated whether maladaptive coping modes would incrementally predict emotional exhaustion (EE) adjusting for resilience and whether resilience might moderate the effect of maladaptive coping on EE. The possible role of maladaptive coping as a mediator of job demands on EE was also explored. Four hundred and forty-three clinical and counselling psychologists completed online measures of job demands, EE, resilience, and maladaptive coping modes. The Detached Protector mode was associated with greater EE after adjusting for resilience. Bully and Attack mode was associated with greater EE when considered separately from other coping modes but associated with decreased EE when considered together. Resilience did not moderate the effect of job demands on EE, or the effect of coping modes on EE, except for Compliant Surrenderer. Coping modes only partially mediated the effect of job demands on EE accounting for 20% or less of its effect. Maladaptive coping modes appear to make independent contributions to the risk of EE and efforts to reduce burnout in psychologists should focus dually on increasing resilience-building practices and decreasing maladaptive coping.

ABSTRACT

Resumen La investigación intercultural plantea desafíos éticos complejos. Por ello, en el año 2019 se desarrolló un modelo de análisis de conflictos éticos en colaboración con más de 200 investigadores de más de 30 países. Este modelo parece pertinente para América Latina. El modelo propone que los desafíos éticos (y sus soluciones) dependen de cuatro factores presentes durante todo el proceso de investigación: el lugar donde se realiza la investigación, las personas involucradas, los principios éticos relevantes y los precedentes de investigaciones pasadas. En este artículo hacemos un análisis de la aplicabilidad de dicho modelo mediante dos análisis de casos referidos a la investigación con pueblos originarios en Chile y al trabajo con latinos migrantes en la frontera México-Estados Unidos.


Abstract Intercultural research poses critical ethical challenges. In 2019, in collaboration with more than 200 researchers from more than 30 countries, a group of researchers developed an ethical conflict analysis model that seems relevant for Latin America. The model proposes a flexible frame of reference where ethical challenges (and their solutions) depend on four factors present throughout the research process: the place where the research is carried out, the people involved, the relevant ethical principles, and the precedents from previous research. This article discusses the applicability of this model through two case analyses: one study with Indigenous peoples in Chile and the other with Latin-American migrants on the border between Mexico and US.

ABSTRACT

BACKGROUND: Early maladaptive schemas (EMS) are self-perpetuating dysfunctional cognitive structures that have been linked with youth psychological health and play a significant role in developing and maintaining psychological distress, including anxiety symptoms. METHOD: The present meta-analysis synthesises the existing literature to evaluate the strength of association between EMS and anxiety symptoms among adolescents and young adults (aged 10-29 years). The systematic literature search was carried out in October 2019 using six different databases. RESULTS: Our systematic search has identified 15 studies, comprising of 9515 participants (Mean age = 18.95, SD = 5.30). All the studies assessed were either cross-sectional or longitudinally designed. The random effect estimate for overall EMS with anxiety was r = 0.59 (95% Cl = 0.50 to 0.68, Z = 9.69, p < 0.0001), indicating a strong association between EMS and anxiety. When different schema domains were investigated separately, anxiety was shown to have significantly stronger associations with the schema domains of disconnection/rejection (r = 0.50), impaired autonomy/performance (r = 0.47) and other-directedness (r = 0.49). Further, females were found to have higher schemas of hypervigilance and other-directedness and associated anxiety symptoms compared to males. LIMITATIONS: Meta-analytical results were limited to articles published in peer-reviewed journals in English language, inducing an upward publication bias and limiting the generalizability of the findings. CONCLUSIONS: The findings highlight schemas related to disconnection/rejection, impaired autonomy/performance and other-directedness as particularly salient precursors of anxiety symptoms, providing evidence for clinicians to target these particular schemas during prevention, intervention, and management of anxiety disorder.

ABSTRACT

Early maladaptive schemas (EMS) are broad, pervasive themes and patterns of emotions, memories, cognition and physical sensations that impede the goal of individuals. Maladaptive behaviours can occur as a response to maladaptive or negative schemas, often culminating in depression or anxiety. The current meta-analysis integrates the existing literature to estimate the magnitude of effect of association between EMS and depression among adolescents and young adults. A systematic search of seven different databases including Embase, CINAHL, Medline, ASSIA, Psych INFO, Scopus and Web of Science was carried out identifying 24 relevant studies of adolescents (10-18 years) and young adults (19-29 years). The random-effect model estimate for association between overall EMS and depression was r = 0.56 (95% CI 0.49-0.63, Z = 12.88, p ≤ 0.0001), suggesting higher predominant EMS significantly linked to higher levels of depressive symptoms, with a large effect size. Separate meta-analytical results with schema domains indicated moderately stronger associations between schemas of disconnection/rejection, impaired autonomy/performance and other-directedness with depression. Age and gender were not found to have any significant moderating effect on the associations. The findings suggest that it is vital for clinicians to identify specific maladaptive schemas contributing towards depression, to have a better understanding of underlying cognitive processes and in turn promote psychological health, well-being and resilience in adolescents and young adults. Furthermore, findings will also assist clinicians to focus more on the content of three significant schema domains, which emerged as particularly salient factors underlying adolescent depression.

ABSTRACT

(1) Background: This article examines whether connection to digital technologies helps connect young Indigenous people in Australia to culture, community and country to support good mental health and well-being and protect against indirect and potentially long-term effects of COVID-19. (2) Method: We reviewed literature published between February and November 2020 and policy responses related to digital strategies. We searched PubMed, Google Scholar, government policy websites and key Indigenous literature sources, identifying 3460 articles. Of these, 30 articles and 26 policy documents were included and analysed to identify existing and expected mental health outcomes among Indigenous young people associated with COVID-19 and more broadly. (3) Results: There are inequities in affordable access to digital technologies. Only 63% of Indigenous people have access to internet at home. Digital technologies and social media contribute to strong cultural identity, enhance connections to community and country and improve mental health and social and emotional well-being outcomes. (4) Discussion: Access to digital technologies can facilitate healing and cultural continuity, self-determination and empowerment for young people to thrive, not just survive, in the future. (5) Conclusion: More targeted policies and funding is urgently needed to promote digital technologies to enhance Indigenous young people's access to mental health and well-being services, maintain cultural connections and evaluate the effectiveness of these initiatives using Indigenous well-being indicators.

ABSTRACT

PROBLEM: The Edinburgh Postnatal Depression Scale (EPDS) is considered the gold standard in perinatal mental health screening and the Australian Clinical Practice Guidelines recommend universal use. However, screening rates are four times lower with Indigenous Australian women compared to non-Indigenous women. Difficulties have been reported using the EPDS in this context. BACKGROUND: Evidence demonstrates the link between perinatal mental health and maternal and child outcomes. Indigenous Australian maternal and child health and wellbeing outcomes remain unacceptably poor across all measured parameters and reported psychological distress and child removal rates are increasing. METHODS: A systematic literature review was conducted to assess the effectiveness, validity, reliability, and cultural safety of the EPDS in the Indigenous Australian context and identify the availability and suitability of any adaptations. FINDINGS: The EPDS has not been validated for use with Indigenous Australian women. DISCUSSION: The findings and limitations identified in this review are consistent with concerns in other countries about the cross-cultural use of the EPDS and its sensitivity in predicting risk for postnatal depression amongst Indigenous women. Where adaptations of the EPDS have been used there has been no psychometric and cultural validation beyond the remote communities in which they were developed. CONCLUSIONS: There is no evidence to demonstrate that the EPDS in its current form and application is suitable for screening with Indigenous Australian women. Urgent work is required to evaluate and/or develop culturally meaningful screening tools that are predictive of risk for social and emotional wellbeing and perinatal mental distress in this context.

ABSTRACT

The arrival of the coronavirus (COVID-19) pandemic has confronted us with a global and unprecedented challenge of community-wide psychological distress alongside reduced access to therapeutic services in the traditional face-to-face format, due to the need to self-isolate. This previously unimagineable set of circumstances provides a unique opportunity, and indeed an imperative, for videotherapy to fulfil its potential in addressing mental health and well-being needs from a distance. Historically, the uptake of videotherapy has been hindered by psychotherapist expectations of inferior therapeutic alliance and outcomes, in spite of considerable research evidence to the contrary. Research suggests that videotherapy provides a powerful pathway for clients to experience enhanced opportunities for self-expression, connection and intimacy. This more neutral therapeutic 'space' provides clients with multifarious opportunities for self-awareness, creative experience and collaboration, with potentially a greater sense of agency over their own experience. This paper explores ways in which videotherapy can lead to a revitalisation of the concept of the therapeutic relationship, in order to meet the challenges associated with COVID-19. A number of specific considerations for videotherapy adaptations and etiquette in the midst of COVID-19 are described.

ABSTRACT

The Edinburgh Postnatal Depression Scale (EPDS) is used extensively as the "gold standard" perinatal depression and anxiety screening tool. This study contributes to an emerging discussion about the tool's shortcomings, specifically around cultural suitability for use with Indigenous women. A systematic search was conducted in ProQuest, PsycINFO, MEDLINE (Web of Science), PubMed, Scopus, Informit, and CINAHL research databases, and grey literature. The quality of the body of evidence was assessed using the NHMRC Level of Evidence framework. Three studies supported the cultural validation of the EPDS with Indigenous groups in Canada (n = 2) and the USA (n = 1). The remaining eleven Australian studies demonstrated that cultural concerns were suggested by either Indigenous mothers, healthcare professionals (Indigenous and non-Indigenous), or both, though cultural concerns were more weighted from the perspectives of healthcare professionals. The quality of the evidence was not strong, and thus, there is a critical and urgent need for targeted research in this area. This review identified and recommended Indigenous-specific methodologies that can be adopted for more trustworthy, culturally safe, and effective research in this area. Given that the EPDS is currently considered gold standard in routine perinatal mental health screening practice in countries around the world, these findings raise significant concerns. Using culturally relevant research methodologies, such as the use of mixed-methods design, could lay stronger groundwork for further investigation of the broader utility and cultural relevance of the tool.

ABSTRACT

Recent studies highlight a range of factors that place psychotherapists at risk of burnout. The aim of this study was to investigate the ethics issues linked to burnout among psychotherapists and to describe potentially effective ways of reducing vulnerability and preventing collateral damage. A purposive critical review of the literature was conducted to inform a narrative analysis. Differing burnout presentations elicit a wide range of ethics issues. High rates of burnout in the sector suggest systemic factors and the need for an ethics review of standard workplace practice. Burnout costs employers and taxpayers billions of dollars annually in heightened presenteeism and absenteeism. At a personal level, burnout has been linked to poorer physical and mental health outcomes for psychotherapists. Burnout has also been shown to interfere with clinical effectiveness and even contribute to misconduct. Hence, the ethical impact of burnout extends to our duty of care to clients and responsibilities to employers. A range of occupational and personal variables have been identified as vulnerability factors. A new 5-P model of prevention is proposed, which combines systemic and individually tailored responses as a means of offering the greatest potential for effective prevention, identification, and remediation. In addition to the significant economic impact and the impact on personal well-being, burnout in psychotherapists has the potential to directly and indirectly affect client care and standards of professional practice. Attending to the ethical risks associated with burnout is a priority for the profession, for service managers, and for each individual psychotherapist.

ABSTRACT

Psychologists are subject to multiple competing emotional demands that increase the risk of burnout. Research has demonstrated that burnout arises from both organizational and personal factors, including psychologists' personal beliefs and coping. Preliminary research indicates that early maladaptive schemas (EMS) are associated with high burnout, yet, to date, the role of EMS and associated coping responses (maladaptive coping modes [MCM]) in predicting high burnout amongst psychologists has not been investigated. Four hundred forty-three psychologists completed a self-report online questionnaire comprising the Maslach Burnout Inventory-emotional exhaustion scale (EE), Young Schema Questionnaire, and Schema Mode Inventory. The two most common EMS amongst psychologists were unrelenting standards and self-sacrifice. There was substantial indication of burnout, with 18.3% in the high range and 29.6% in the moderate range of EE. The most common MCM were detached protector and detached self-soother. Controlling for demographics and job demands, EMS accounted for an additional 18% variance in EE. MCM accounted for an additional 6% beyond the variance explained by demographics, job demands, and EMS. Practical recommendations are suggested to reduce psychologist burnout.

ABSTRACT

INTRODUCTION: Adopting a process-oriented framework for test validation can help to establish whether this tool has the potential to be an acceptable, valid and reliable indicator of depression for mothers and mothers-to-be. This mixed-methods research protocol seeks to explore the views and experiences of Aboriginal mothers and healthcare professionals in relation to the Edinburgh Postnatal Depression Scale (EPDS), and is intended to highlight potential barriers in perinatal mental health conceptualisation, engagement and response style. METHODS AND ANALYSIS: Thematic analysis will be applied to interview transcripts of Aboriginal Australian mothers (n=6+) and healthcare professionals (n=6+) to identify key themes. The process-focused validation model will use narratives about experiences of using the EPDS as the priority point of analysis. Item-level data and process-level (experience) data are key phenomenological data. The interview-based narratives will be then compared with EPDS scores to check for points of congruence and divergence. This will be done at two time points, antenatally and postnatally, to assess changes in assessment processes and perceptions. Bridging evidence-based research with clinical practice in an Aboriginal Australian context will be facilitated by an investigation of the perceived cultural relevance and likely clinical effectiveness of EPDS. Such evidence is critical to understanding whether the EPDS fulfils its intended purpose. The guiding principles in designing this research protocol is to benefit the well-being of young Aboriginal families and communities through partnership with Aboriginal women. ETHICS AND DISSEMINATION: Ethics approval was obtained from Human Research Ethics Committee of Murdoch University and from Western Australian Aboriginal Health Ethics Committee (WAAHEC). Participating healthcare sites and services have provided letters of support. Results of this study will be submitted for publication in a peer-reviewed journal.

ABSTRACT

Inhibition and switching are executive functions (EFs) that have different developmental trajectories across childhood. The development of specific processes unique to each EF may contribute to these trajectories. Interference suppression and reversal were examined in a large sample of children aged 7 and 9 years (n = 120) and followed-up after two-years to investigate developmental trajectories of inhibition and switching. The N2 and P3b components provided neural correlates of conflict monitoring and attentional processing of conflict involved in interference suppression and reversal. Interference suppression improved over time, however, switching performance did not significantly change between 7 and 11 years. Improvements in correct RT with age and time indicated increased efficiency of stimulus evaluation, response preparation and execution. N2 amplitude decreased with both age and time, indicating less reliance on conflict monitoring to signal cognitive control to manage stimulus and response conflict. P3b amplitude modulations indicated that different amounts of attention were allocated to updating mental representations of interference suppression and reversal task features. These data indicated different developmental trajectories of specific processes unique to inhibition and switching across the childhood period of 7-11 years, providing further empirical evidence that 7-11 years is a critical period for cognitive development.

ABSTRACT

The asymmetric sampling in time hypothesis (AST) suggests that the left and right secondary auditory areas process auditory stimuli according to different sampling rates (Poeppel, 2003). We investigated whether asymmetries consistent with the AST are observable in children at age 7 and whether they become more pronounced at age 9. Data were collected from 50 children who attended a 2-day research program at age 7 and were followed up 2 years later. At both time points, children were presented with tone-pairs, each composed of two 50 ms, 1000 Hz, sinusoidal tones separated by inter-stimulus intervals (ISIs) of 25, 50, 100, or 200 ms. Stimuli were presented binaurally whilst the EEG was recorded. The Ta and Tb, which are components of the auditory event-related potential (ERP), were used as electrophysiological indices of auditory processing. There was no significant effect of age on Ta or Tb responses. Tb responses to the second tone of tone-pairs indicated a left-hemisphere preference for rapidly presented stimuli (50 ms ISI) and a right hemisphere preference for more slowly presented stimuli (100 and 200 ms ISI). The results provide evidence that auditory areas of the left hemisphere preferentially respond to fast temporal rates, and those of the right hemisphere preferentially respond to slow temporal rates in children at age 7 and 9. In 7-year-old children, leftward lateralisation of responses to rapidly presented tones predicted better phonemic decoding ability 2 years later, which suggests that hemispheric specialisation may be a precursor for subsequent phonemic decoding skills.

ABSTRACT

AIM: To estimate the association between very preterm birth (<32wks' gestation) and intelligence, executive functioning, and processing speed throughout childhood and adolescence, and to examine the effects of gestational age, birthweight, and age at assessment. METHOD: Studies were included if children were born at earlier than 32 weeks' gestation, aged 4 to 17 years, had an age-matched term control group, and if the studies used standardized measures, were published in an English-language peer-reviewed journal, and placed no restrictions on participants based on task performance. RESULTS: We evaluated 6163 children born very preterm and 5471 term-born controls from 60 studies. Children born very preterm scored 0.82 SDs (95% confidence interval [CI] 0.74-0.90; p<0.001) lower on intelligence tests, 0.51 SDs (95% CI 0.44-0.58; p<0.001) lower on measures of executive functioning, and 0.49 SDs (95% CI 0.39-0.60; p<0.001) lower on measures of processing speed than term-born controls. Gestational age and birthweight were associated with study effect size in intelligence and executive functioning of younger children only. Age at assessment was not associated with study effect size. INTERPRETATION: Children born very preterm have medium to large deficits in these cognitive domains. WHAT THIS PAPER ADDS: This meta-analysis is centred on very preterm birth and three cognitive domains. The three critical cognitive domains are intelligence, executive functioning, and processing speed.
