'Doing culture' in contemporary south-eastern Australia: how Indigenous people are creating and maintaining strong cultural identities for improved health and wellbeing.

BACKGROUND: Indigenous people in Australia experience far poorer health than non-Indigenous Australians. A growing body of research suggests that Indigenous people who are strong in their cultural identity experience better health than those who are not. Yet little is known about how Indigenous people create and maintain strong cultural identities in the contemporary context. This paper explores how Indigenous people in south-eastern Australia create and maintain strong cultural identities to support their health and wellbeing. METHODS: Data were collected from 44 Indigenous people living in the south-eastern Australian state of Victoria via yarning. Yarning is a cultural mode of conversation that privileges Indigenous ways of knowing, doing and being. Yarning participants were selected for their prominence within Victorian Indigenous health services and/or their prominence within the Victorian Indigenous community services sector more broadly. Due to the restrictions of COVID-19, yarns were conducted individually online via Zoom. Data were analysed employing constructivist grounded theory, which was the overarching qualitative research methodology. RESULTS: All yarning participants considered maintaining a strong cultural identity as vital to maintaining their health and wellbeing. They did this via four main ways: knowing one's Mob and knowing one's Country; connecting with one's own Mob and with one's own Country; connecting with Community and Country more broadly; and connecting with the more creative and/or expressive elements of Culture. Importantly, these practices are listed in order of priority. Indigenous people who either do not know their Mob or Country, or for whom the connections with their own Mob and their own Country are weak, may therefore be most vulnerable. This includes Stolen Generations survivors, their descendants, and others impacted by historical and contemporary child removal practices. CONCLUSIONS: The yarns reveal some of the myriad practical ways that Indigenous people maintain a strong cultural identity in contemporary south-eastern Australia. While programs designed to foster connections to Community, Country and/or Culture may benefit all Indigenous participants, those most disconnected from their Ancestral roots may benefit most. Further research is required to determine how best to support Indigenous Victorians whose connections to their own Mob and their own Country are unable to be (re)built.

Exploring the association of Indigeneity, social adversity status and externalizing symptoms in children and adolescents.

OBJECTIVE: The relationship between Indigeneity, social adversity status and externalizing symptoms is complex and unclear. This study investigates how Indigeneity, social adversity status and externalizing symptoms are related in young people. METHODS: A total of 132 Indigenous and 247 non-Indigenous young people aged 6-16 years were recruited from a hospital mental health outpatient service. Normality plots with statistics for social adversity status and parent-reported externalizing symptoms were completed for the two groups, matched for age, gender, mental disorder symptom severity, symptom-linked distress and impairment. Standard multiple regression was used to examine how Indigeneity moderates the relationship between social adversity status and parent-reported externalizing symptoms. A scatterplot investigated the association between Indigeneity and social adversity status in young people with parent-reported externalizing symptoms. RESULTS: The distributions of the two groups and (1) social adversity status and (2) parent -reported externalizing symptoms were non-normal but acceptable for a moderator analysis. Indigeneity and social adversity status made independent significant positive contributions to externalizing symptoms. In contrast the interaction between Indigeneity and social adversity status made a nonsignificant negative trend to externalizing symptoms. A scatterplot revealed Indigeneity moderated the link between social adversity status and externalizing symptoms. CONCLUSIONS: High social adversity status is linked to externalizing symptoms in non-Indigenous young people but despite higher social adversity, Indigenous young people don't necessarily externalize. Potential protective resilience factors for externalizing symptoms in the Indigenous young people need to be ascertained and nurtured. Future systematic investigations of the contribution of these protective factors to Indigenous referral pathways and management are needed. It is also crucial that increased social adversity status is addressed and managed in all young people, regardless of Indigeneity.

Indigenous Spirituality, Health, and Well-Being in the Young: Yarns With the Victorian Aboriginal Community.

The extant literature has scant detail about everyday spiritual practices that aid Indigenous young people. This paper systematically explores Indigenous Spirituality, health, and well-being through Elder-governed yarns conducted via Zoom with 44 Aboriginal Elders, Healers, and Senior and Junior people involved in health and well-being of the Victorian Aboriginal community. These yarns were analyzed through an innovative, constructivist, multi-perspectival discursive grounded theory method. Key findings are that Spirituality is crucial for health and well-being, leading to a clear mind and at-peace "center" in a person. Aboriginal spiritual practices reflect the unique characteristics and essential rhythms of Country. Spiritual development is incremental and increases the obligations and responsibilities a person has to community and Country and leads to increased caring for Country. This paper provides rich detail about practical spiritual techniques to aid Indigenous young people and their kinship networks. It has the potential to shape future policy.

The Development of Elder-Governed Adjuvant Cultural Therapy for Aboriginal and/or Torres Strait Islander Young People With Mental Health Conditions.

A 10-year review of the 2008 Council of Australian Governments' (COAG) Close the Gap Strategy identified the lack of involvement of Indigenous people in developing policies as a key reason health disparities persist. It also posits that disconnection from Country and culture have been crucial factors. Physical and mental health cannot be separated from spiritual health and well-being amongst Indigenous Australians. This article describes the co-development of a cultural enrichment research study with Indigenous Elders, health service leaders, and community members that places culture at the centre of care to augment traditional Western mental health management. The study has been overseen and nurtured from its inception by a governance board of Traditional Custodian Elders and an Advisory Group of Indigenous health workers. Qualitative data were collected through community 'zoom-yarns' between an Indigenous research assistant and 44 community members during COVID-19 lockdowns. These yarns were analysed through an innovative, constructivist, multi-perspectival discursive grounded theory method. Findings have led to an Elder-governed adjuvant cultural therapy which is currently being trialled and will be evaluated using the same multi-perspectival discursive grounded theory research methodology. One third of all Indigenous Australians now live in capital cities, so developing models to bring culture and Country into urban health facilities are becoming increasingly important. The Indigenous-led research approach outlined in this paper suggests a model for engaging Indigenous communities that mainly distrust Western research and have been failed by Western mental health care. It has the potential to shape future policy.

Country and community vs poverty and conflict: Teasing apart the key demographic and psychosocial resilience and risk factors for Indigenous clinic-referred children and adolescents.

OBJECTIVE: Indigenous young people are known to have adverse demographic and psychosocial factors affecting worse mental health outcomes and some household factors aiding resilience. In Australia, there has been no exploration of these factors in clinically referred Indigenous young people assessed in a culturally appropriate way. METHODS: A total of 113 Indigenous children and adolescents, 217 non-Indigenous young people, age, gender, mental disorder symptom severity, symptom-linked distress and impairment matched, and 112 typically developing participants, age- and gender-matched were recruited. Cultural validity and reliability of the impairing symptoms in Indigenous young people were determined. Key demographic and psychosocial factors were compared across the three groups. RESULTS: The Indigenous clinical group differed significantly from the other two groups that did not differ on three possibly protective measures examined. Key demographic and psychosocial risk factors in the Indigenous group differed significantly from the non-Indigenous clinical group which in turn differed from the typically developing participants. The three groups exhibited a progressively increased magnitude of difference. CONCLUSIONS: It remains imperative to nurture features that provide protection and enhance resilience for Indigenous young people and their communities. Indigenous status is linked to significant demographic and psychosocial disadvantage over and above that conferred by clinical impairment and its management. It is crucial that these features are managed and/or advocated for with those demographic and psychosocial factors of the greatest magnitude dealt with first. Future systematic investigations of the contribution of these key factors to mental health referral pathways, assessment and management are needed.

Distinct Neural Profiles of Frontoparietal Networks in Boys with ADHD and Boys with Persistent Depressive Disorder.

Working memory deficits are common in attention-deficit/hyperactivity disorder (ADHD) and depression-two common neurodevelopmental disorders with overlapping cognitive profiles but distinct clinical presentation. Multivariate techniques have previously been utilized to understand working memory processes in functional brain networks in healthy adults but have not yet been applied to investigate how working memory processes within the same networks differ within typical and atypical developing populations. We used multivariate pattern analysis (MVPA) to identify whether brain networks discriminated between spatial versus verbal working memory processes in ADHD and Persistent Depressive Disorder (PDD). Thirty-six male clinical participants and 19 typically developing (TD) boys participated in a fMRI scan while completing a verbal and a spatial working memory task. Within a priori functional brain networks (frontoparietal, default mode, salience), the TD group demonstrated differential response patterns to verbal and spatial working memory. The PDD group showed weaker differentiation than TD, with lower classification accuracies observed in primarily the left frontoparietal network. The neural profiles of the ADHD and PDD differed specifically in the SN where the ADHD group's neural profile suggests significantly less specificity in neural representations of spatial and verbal working memory. We highlight within-group classification as an innovative tool for understanding the neural mechanisms of how cognitive processes may deviate in clinical disorders, an important intermediary step towards improving translational psychiatry.

Key demographic and mental disorder diagnostic differences between Australian First Nations and non-First Nations clinic-referred children and adolescents assessed in a culturally appropriate and safe way.

OBJECTIVE: Increased point prevalence rates of oppositional defiant disorder and conduct disorder have been reported in American Indian and Canadian First Nations children and adolescents. To date, in Australia, there has been no published examination of standardized Diagnostic and Statistical Manual mental disorder diagnoses in First Nations children and adolescents, determined after addressing key cultural methodological issues. METHODS: In all, 113 First Nations children and adolescents and 217 non-First Nations young people, aged 6-16 years, age, gender, mental disorder symptom severity, symptom-linked distress and impairment matched were recruited in a case control study. Also, 112 typically developing non-First Nations participants, age and gender matched to the other two clinical groups as a second comparison group were recruited. Diagnostic and Statistical Manual mental disorder diagnoses via semi-structured clinical interview, social adversity status and full scale IQ were determined in all participants with cultural validity and reliability of the impairing patterns of symptoms in First Nations young people determined by First Nations mental health staff and Aboriginal Health Liaison Officers. Full scale IQ and social adversity status were appropriately controlled in the Logistic Regression analyses of Diagnostic and Statistical Manual mental disorder diagnoses between the two clinical groups. RESULTS: Oppositional defiant disorder was the only diagnostic and statistical manual mental disorder diagnosis that differed between the First Nations and non-First Nations clinical groups, adjusting for confounding by social adversity status and full scale IQ in the multivariable model. The point prevalence of oppositional defiant disorder was 2.94 times higher (95% confidence interval: 1.14-7.69) among the First Nations compared to the non-First Nations clinical group. CONCLUSION: Key known risk factors for oppositional defiant disorder can be identified early and holistically managed in First Nations young people. This will prevent oppositional defiant disorder decreasing their access to mental health services and increasing their involvement in the criminal justice system. In addition, the resilience building aspects of oppositional defiant disorder that may enhance self-respect need to be nurtured.

Gender Variance in Children and Adolescents with Neurodevelopmental and Psychiatric Conditions from Australia.

Gender variance is a broad term used to describe gender non-conforming behaviors. Past studies have used the parental response to Child Behavior Checklist (CBCL) Item 110, which asks whether a child "Wishes to be of opposite sex" as an indicator of gender variance. The population prevalence of gender variance in children and adolescents using this metric was found to be 1.2% in birth-assigned females and 0.4% in birth-assigned males (Achenbach & Rescorla, 2001). However, in those referred for psychiatric evaluation, it was higher (5.4% of birth-assigned females and 2.8% of birth-assigned males) (Achenbach & Rescorla, 2001). The aim of this study was to use the CBCL to estimate the prevalence of gender variance among children and adolescents with neurodevelopmental and psychiatric conditions and assess whether this was higher compared to controls. The response to the CBCL and the child's neurodevelopmental and/or psychiatric diagnosis were extracted from the clinical notes of 1553 children and adolescents referred to an outpatient psychiatry clinic in Australia. This was compared to data from 181 control participants as well as to the CBCL standardization sample of 1605 controls. Of the 1553 young people, whose mean age was 10.9 years, gender variance was reported in 3.1% compared to 1.7% in local control participants (p > .05) and 0.7% in the CBCL controls (p < .0001). Rates varied depending upon the underlying diagnosis (ASD 5.2%; ADHD 2.5%, intellectual disability 4.7%; depression 2.6%; and anxiety 4.7%). In this way, our findings support past observations that young people with neurodevelopmental and psychiatric conditions have high rates of gender variance.

Irritability and Inattention Not Sad Low Mood Predict Impulsiveness in Children and Adolescents With Major Depressive Disorder and Persistent Depressive Disorder.

ABSTRACT: The specific relationships between impulsiveness, inattention, sad, low mood, and irritability have not been systematically examined in young people with major depressive disorder with and without persistent depressive disorder. The relationships are important to clarify because these symptom dimensions may increase suicidal risk in children and adolescents with these depressive disorders. A total of 313 medication-naive young people (aged 6-16 years) with active major depressive disorder (MDD) alone, persistent depressive disorder (DD) alone, and comorbid MDD and DD were identified. "Inattention," "sad/unhappy," and "irritable" mood were identified by parent standardized questionnaire. Standard multiple regression was used to investigate how well inattention, sad/unhappy, and irritable mood predict impulsiveness. Inattention (32% of the variance, increased) and irritable mood (5% of the variance, increased) both made independent significant contributions to impulsiveness, whereas sad/unhappy mood did not. Decreasing irritability via more targeted and comprehensive management approaches may ameliorate impulsiveness in young people with these depressive disorders.

Irritability, Depressed Mood, Inattention and Spatial Working Memory in Children and Adolescents with Major Depressive Disorder With/Without Persistent Depressive Disorder.

The specific relationships between sad/low mood, irritability, inattention and spatial working memory (SWM) have not been systematically examined in young people with major depressive disorder with and without persistent depressive disorder. 313 medication naïve young people (aged 6-16 years) with active major depressive disorder (MDD) alone, persistent depressive disorder (DD) alone and comorbid active MDD and DD were identified. Standard multiple regression was used to investigate how well SWM components-Spatial Span, Strategy and Between Search Errors (BSE)-predict 'sad/unhappy', 'irritable' mood and 'Inattention'. Spatial Span (4% of the variance-decreased), Strategy and BSE (both 1% of the variance increased) all made independent significant contributions to 'Inattention' while having no independent association with 'sad/unhappy' or 'Irritable' mood. These findings support the independence of depressive cognitive impairment from the two main components of depressive mood. Improving SWM and attention via targeted management approaches may aid young people with these depressive disorders.

Parent- and child-reported anxiety disorders differentiating major depressive disorder and dysthymic disorder in children and adolescents.

OBJECTIVE: To date, specific parent- and child-defined anxiety disorders associated with dysthymic disorder (DD; DSM-5 persistent depressive disorder equivalent) with and without major depressive disorder (MDD) have not been investigated in children and adolescents. METHOD: In a cross-sectional study, we compared point prevalence rates of parent- and child-reported anxiety disorders in DD alone (N = 154), MDD alone (N = 29), comorbid DD and MDD (N = 130) and anxiety disorders alone (N = 126) groups. RESULTS: DD alone and MDD alone did not differ with respect to comorbid anxiety disorders from parent and child reports, while parent-reported panic disorder (PD) was significantly increased in the DD and MDD group compared to the other three groups as was child-reported post-traumatic stress disorder (PTSD) compared to the MDD alone and anxiety disorders alone groups. In contrast, specific phobia (SpPh) was significantly increased in the anxiety disorders alone group compared to the DD and MDD group. CONCLUSION: The findings suggest that specific fear-related anxiety disorders, especially parent-reported PD and child-reported PTSD, may aid the early recognition of DD and MDD.

Mental health care for Indigenous young people: moving culture from the margins to the centre.

OBJECTIVE: Recently, Indigenous academics have evolved an Indigenist discourse that centralises Indigenous 'ways of knowing, being and doing'. Through this dialogue, Indigenous 'ways of knowing and being' augment Western biopsychosocial treatments. METHODS: This paper outlines the authors' clinical encounters with young people from the Koori community and ongoing consultation with Koori community Elders in Victoria that led to engaging young people and their families in an Indigenist dialogue. RESULTS: The Indigenist dialogue facilitates deeper engagement in the therapeutic process, opportunities to mirror and reflect on young people's experiences, and drawing parallels between Western health interventions and Aboriginal cultural ways of doing health and being healthy. CONCLUSIONS: The young people and their families evince greater faith in the management process and a deeper focus, centred awareness and knowledge of their Cultural rights and responsibilities. Future developments should include a systematic database with qualitative and quantitative data to support its evaluation and iterative development and improved community engagement to ensure holistic health gains are maintained.

Executive function and attention in children and adolescents with depressive disorders: a systematic review.

Numerous studies have shown that Major Depressive Disorder (MDD) in adults is associated with deficits in cognitive control. Particularly, impairment on executive function (EF) tasks has been observed. Research into EF deficits in children and adolescents with MDD has reported mixed results and it is currently unclear whether paediatric MDD is characterised by impairments in EF and attention. PsycInfo, Scopus and Medline were systematically searched to identify all studies that have investigated EF and attention in paediatric depressive disorders between 1994 and 2014. 33 studies meeting inclusion/exclusion criteria were identified. While across different domains of EF some studies identified a deficit in the clinical group, the majority of studies failed to find deficits in response inhibition, attentional set shifting, selective attention, verbal working memory, and verbal fluency. More research is needed to clarify the relationship between depressive disorders in children and adolescents and spatial working memory processing, sustaining attention, planning, negative attentional bias and measures of 'hot' EF. There is little support for EF deficits in paediatric depression. However, there are numerous methodological problems that may account for null findings. Alternatively, chronicity and/or severity of symptoms may explain discrepancies between cognitive deficits in adult and paediatric MDD. Recommendations for future studies are discussed.

Differential effects of anxiety and depressive symptoms on working memory components in children and adolescents with ADHD combined type and ADHD inattentive type.

Working memory (WM) deficits have been shown to be associated with core ADHD symptoms, worse academic achievement and peer-relationship problems. Internalizing symptoms, such as anxiety and depression, have also been associated with impaired WM performance. However, the association of anxiety and depression and WM performance remains unclear for children and adolescents with ADHD. Further, it is unknown how these comorbid conditions might affect WM performance in the two main ADHD subtypes. The association of anxiety and depression and the specific components of spatial (SWM) and verbal working memory (VWM) were examined in 303 children and adolescents with ADHD, combined type (ADHD-CT) and 77 ADHD, inattentive type (ADHD-IA) compared to 128 age- and gender-matched typically developing participants. The relationship between anxiety and depression and WM was assessed using multiple linear regression analyses and separate simple regression analyses. Higher levels of anxiety/depression were associated with (1) increased between-search errors in the typically developing participants alone, (2) a better strategy performance in the ADHD-CT group, and (3) a better spatial span performance in the ADHD-IA group. VWM was equally impaired in the ADHD-CT and ADHD-IA groups, independent of the levels of anxiety and depression. The results suggest that the effects of internalizing symptoms on WM differ in typically developing children and adolescents compared to those with ADHD. Further, high levels of anxiety and depression modified WM performance differently according to the specific ADHD subtypes. This might help explain contradictory findings observed in previous studies of mixed samples of participants with ADHD-CT and ADHD-IA.

The COMT Val158 allele is associated with impaired delayed-match-to-sample performance in ADHD.

BACKGROUND: This study explored the association between three measures of working memory ability and genetic variation in a range of catecholamine genes in a sample of children with ADHD. METHODS: One hundred and eighteen children with ADHD performed three working memory measures taken from the CANTAB battery (Spatial Span, Delayed-match-to-sample, and Spatial Working Memory). Associations between performance on working memory measures and allelic variation in catecholamine genes (including those for the noradrenaline transporter [NET1], the dopamine D4 and D2 receptor genes [DRD4; DRD2], the gene encoding dopamine beta hydroxylase [DBH] and catechol-O-methyl transferase [COMT]) were investigated using regression models that controlled for age, IQ, gender and medication status on the day of test. RESULTS: Significant associations were found between performance on the delayed-match-to-sample task and COMT genotype. More specifically, val/val homozygotes produced significantly more errors than did children who carried a least one met allele. There were no further associations between allelic variants and performance across the other working memory tasks. CONCLUSIONS: The working memory measures employed in the present study differed in the degree to which accurate task performance depended upon either the dynamic updating and/or manipulation of items in working memory, as in the spatial span and spatial working memory tasks, or upon the stable maintenance of representations, as in the delay-match-to-sample task. The results are interpreted as evidence of a relationship between tonic dopamine levels associated with the met COMT allele and the maintenance of stable working memory representations required to perform the delayed-match-to-sample-task.

Examination of neurological subtle signs in ADHD as a clinical tool for the diagnosis and their relationship to spatial working memory.

BACKGROUND: Neurological subtle signs (NSS) are minor neurological abnormalities that have been shown to be increased in a number of neurodevelopmental conditions. For attention deficit/hyperactivity disorder (ADHD), it remains unclear whether NSS may aid the clinical diagnostic process. METHODS: This study explored the association of total and specific domains of NSS in 1,055 children and adolescents with ADHD compared to 130 age-matched typically developing participants; the relationship between NSS and Spatial Working Memory (SWM) as a cognitive process integrally involved in ADHD was also assessed. To determine the diagnostic and predictive efficiency of NSS, a receiver operating curve analysis was performed and the area under the curve (AUC) quantified. The best discriminant points for differentiating between ADHD and typically developing participants and the predictive power of NSS for SWM impairment in ADHD young people were also calculated. RESULTS: Area under the curves for total NSS, smoothness/accuracy, cerebellar signs and choreo-athetoid movements scores were considered good (.84, .79, .74 and .73 respectively), and the results remained after controlling for gender and IQ. A total score of 13 or over on the Scored Developmental Neurological Examination proved to be a good threshold point for differentiating between the ADHD and typically developing participants. For ADHD children, the AUC of total NSS to distinguish between those below 25th and above 75th percentile were .77 and .73 for Spatial Span and for Between Search Errors respectively (the two SWM-dependent measures examined). CONCLUSIONS: This study provides evidence suggesting that NSS may aid the clinical evaluation of a child or adolescent with ADHD. In children and adolescents with ADHD, NSS are associated with difficulties in SWM, specifically the Spatial Span and Between Search Error components.

Management of attention-deficit/hyperactivity disorder: the importance of psychosocial and medication treatments.

Attention-deficit/hyperactivity disorder (ADHD) assessment and treatment in children and adolescents is complex. Key biological and psychosocial risk factors need to be identified and treated because of their potential mediating interaction that affect the onset, progression, and psychosocial and medication treatment response of core ADHD symptoms and common associated co-morbid conditions. Both psychosocial and medication treatments, alone and in combination, have been shown to reduce the core ADHD symptoms and those of its key co-morbid disorders. Yet, to date, the potential synergism between targeted and specific medication and psychosocial treatments remains poorly understood and under-researched. Interestingly, recent positron emission tomography findings emphasise the importance of contextual salience and positive reinforcement strategies for stimulant medication, the primary medication treatment for ADHD, to have its effect. This is not surprising, given recent epigenetic models of gene-environment interaction that are revolutionising our understanding of developmental disorders like ADHD. This annotation briefly outlines the emerging evidence that supports the role of psychosocial treatment alongside medication treatment in the management of ADHD. Future significant clinical directions are noted.

Whose place? Lessons from a case study of a guardianship determination for an Australian Indigenous child.

Whose values matter when considering which environment is healthier for a child whose guardianship is contested? The biological mother from a remote Australian Aboriginal community, who voluntarily relinquished her but has now requested her return? The foster mother who has cared for her in a metropolitan centre in another State of Australia, thousands of kilometres away? The welfare professionals who also live in that city? Or the child herself, who left her birth home and community five years earlier at the age of two? Drawing on a case study of a seven-year old Aboriginal girl, the authors argue that non-Indigenous values trumped Indigenous values without the realisation of key players who were empowered to make such determinations. The article uses Manuel DeLanda's neo-assemblage theory to consider the range of processes that exert themselves to shape place-values and social identity in colonised nations. It will also draw on Erik Erikson's and Lev Vygotsky's theories of psychosocial development to consider competing sets of values that raised feelings of dissonance within the child. Beliefs about what makes a place health-giving are revealed to be complex in colonised nations. Despite policy and legislative changes to better support Aboriginal people and their right to difference, non-Indigenous professionals can continue to be driven by an unrecognised systemic racism. While place-values are not, of course, the only (or perhaps even the most significant) consideration in guardianship determinations, this article will argue they can play a significant and covert role.

Spatial working memory performance in children and adolescents with major depressive disorder and dysthymic disorder.

BACKGROUND: Spatial working memory (SWM) is known to be impaired in children with Major depressive disorder (MDD), and, separately, Dysthymic disorder (DD) (DSM V persistent depressive disorder equivalent). Yet, it remains unclear whether MDD or DD is associated with worse SWM impairment, whether DD adds to the SWM impairments evident in MDD and whether these findings are evident in children as well as adolescents with MDD and DD. METHODS: The association of SWM and its strategy and spatial span components is explored in carefully defined children and adolescents (age 6-16 years) with MDD alone (N = 29), MDD and DD (N = 130), DD alone (N = 154) compared to healthy typically developing participants (N = 107), controlling for age, gender, full scale IQ and social adversity status. The relationship between SWM and its strategy and span components and anxious/depressed and inattentive symptoms were also examined. RESULTS: MDD was associated with worse SWM impairment than DD and there was no evidence of an additive effect of MDD and DD on SWM, strategy and spatial span deficits. Further, these findings were age-independent. LIMITATIONS: The data presented are cross sectional and limited to SWM deficits in MDD and/or DD. CONCLUSIONS: This study concurs with and extends current influential models about the cognitive effects of MDD and DD. Clinical implications and future research directions are discussed.
