Abstract
Up to 70% of patients with major depressive disorder present with psychomotor disturbance (PmD), but at the present time understanding of its pathophysiology is limited. In this study, we capitalized on a large sample of patients to examine the neural correlates of PmD in depression. This study included 820 healthy participants and 699 patients with remitted (n = 402) or current (n = 297) depression. Patients were further categorized as having psychomotor retardation, agitation, or no PmD. We compared resting-state functional connectivity (ROI-to-ROI) between nodes of the cerebral motor network between the groups, including primary motor cortex, supplementary motor area, sensory cortex, superior parietal lobe, caudate, putamen, pallidum, thalamus, and cerebellum. Additionally, we examined network topology of the motor network using graph theory. Among the currently depressed 55% had PmD (15% agitation, 29% retardation, and 11% concurrent agitation and retardation), while 16% of the remitted patients had PmD (8% retardation and 8% agitation). When compared with controls, currently depressed patients with PmD showed higher thalamo-cortical and pallido-cortical connectivity, but no network topology alterations. Currently depressed patients with retardation only had higher thalamo-cortical connectivity, while those with agitation had predominant higher pallido-cortical connectivity. Currently depressed patients without PmD showed higher thalamo-cortical, pallido-cortical, and cortico-cortical connectivity, as well as altered network topology compared to healthy controls. Remitted patients with PmD showed no differences in single connections but altered network topology, while remitted patients without PmD did not differ from healthy controls in any measure. We found evidence for compensatory increased cortico-cortical resting-state functional connectivity that may prevent psychomotor disturbance in current depression, but may perturb network topology. Agitation and retardation show specific connectivity signatures. Motor network topology is slightly altered in remitted patients arguing for persistent changes in depression. These alterations in functional connectivity may be addressed with non-invasive brain stimulation.

Abstract
Dopamine dysregulation is known to play a major role in the pathophysiology of major depressive disorders (MDD) and bipolar disorders (BD). The dopamine transporter (DAT) plays a critical role in regulating dopamine concentration at the synaptic cleft and therefore could have an important role in the molecular pathology of MDD and BD. To test this hypothesis, we measured levels of [3H]mazindol binding to DAT in Brodmann's area (BA) 10, BA 17 as well as in the dorsal and ventral striatum from 15 controls, 15 patients with MDD and 15 patients with BD, obtained postmortem, using in situ radioligand binding with autoradiography. Compared to controls, levels of [3H]mazindol binding to DAT was significantly higher in BA10 from patients with MDD but not BD. There was no significant difference in [3H]mazindol binding to DAT in BA 17 or the dorsal and ventral striatum from patients with MDD or BD. In addition, levels of [3H]mazindol binding show no correlation with donor age, postmortem interval, tissue pH, sex or duration of illness. In conclusion, our data suggest that changes in levels of DAT may be selectively affecting dopamine homeostasis in BA 10 in patients with MDD.

Abstract
OBJECTIVE Depression is one of the most prevalent and disabling mental health conditions among young people worldwide. The health and economic burdens associated with depressive illness are substantial. Suicide and depression are closely intertwined, yet a diagnosis of depression itself lacks predictive specificity for suicidal behaviour. To better inform suicide prevention and early intervention strategies for young people, improved identification of modifiable intervention targets is needed. The objective of this review was to identify clinical, psychosocial and biological correlates of suicidality in young people diagnosed with a broad range of unipolar and bipolar depressive disorders. METHOD Systematic searches were conducted across MEDLINE, Embase and PsycINFO to identify studies of young people aged 15-25 years diagnosed with unipolar or bipolar depressive disorders. An assessment of suicidality was required for inclusion. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 and Synthesis Without Meta-analysis guidelines. RESULTS We integrated findings from 71 studies including approximately 24,670 young people with clinically diagnosed depression. We identified 26 clinical, psychosocial and biological correlates of suicidality. Depression characteristics (type and severity), psychiatric comorbidity (particularly anxiety and substance use disorders) and neurological characteristics emerged as having the most evidence for being associated with suicidal outcomes. Our ability to pool data and conduct meaningful quantitative synthesis was hampered by substantial heterogeneity across studies and incomplete reporting; thus, meta-analysis was not possible. CONCLUSION Findings of this review reinforce the notion that suicidality is a complex phenomenon arising from the interplay of multiple contributing factors. Our findings question the utility of considering a diagnosis of depression as a specific risk factor for suicidality in young people. Suicidality itself is transdiagnostic; adoption of a transdiagnostic approach to investigating its aetiology and treatment is perhaps warranted. Future research investigating specific symptoms, or symptom networks, might help to further our understanding of suicidality among young people experiencing mental illness.

Abstract
BACKGROUND Motor abnormalities are strong transdiagnostic indicators of psychopathology risk that reflect emerging neural network abnormalities. Indeed, motor signs, such as motor slowing and agitation, are widely recognized as core features of both psychosis and depression. However, it is unclear whether these reflect shared or distinct etiology. METHODS A sample of 11 878 adolescents completed self-reported clinical measures of rated psychotic-like experiences (PLEs) and depression. Familial risk for psychopathology and the presence of motor signs were drawn from parental reports, including developmental motor delays (eg, sitting, walking), and adolescent motor signs (eg, dyscoordination, psychomotor retardation, and psychomotor agitation). Finally, motor network connectivity in theoretically relevant networks (cortico-striatal, cortico-thalamic, and cortico-cerebellar) were related to symptoms and familial risk for psychopathology. RESULTS Developmental motor delays related to increased PLEs, increased depression symptoms, and greater familial risk. Familial risk for both PLEs and depression showed higher rates of developmental motor delays than all other groups. Adolescent motor signs, however, showed unique patterns of relationships to symptoms and familial risk such that dyscoordination reflected risk for PLEs, both psychomotor agitation and retardation reflected depression risk, and psychomotor agitation reflected transdiagnostic risk. Cortico-striatal connectivity was related to depression and PLEs, but cortico-cerebellar connectivity was linked to PLEs only. CONCLUSIONS Motor signs may be a transdiagnostic marker of vulnerability for psychopathology. Early developmental motor delays could belie pluripotent, familial risk features. Unique items, eg, dyscoordination specifically related to PLEs, possibly reflecting processes inherent in distinct emerging forms of psychopathology.

Abstract
Psychomotor slowing is a key feature of depressive disorders. Despite its great clinical importance, the pathophysiology and prevalence across different diagnoses and mood states are still poorly understood. Actigraphy allows unbiased, objective, and naturalistic assessment of physical activity as a marker of psychomotor slowing. Yet, the true effect-sizes remain unclear as recent, large systematic reviews are missing. We conducted a novel meta-analysis on actigraphically measured slowing in depression with strict inclusion and exclusion criteria for diagnosis ascertainment and sample duplications. Medline/PubMed and Web-of-Science were searched with terms combining mood-keywords and actigraphy-keywords until September 2021. Original research measuring actigraphy for ⩾24 h in at least two groups of depressed, remitted, or healthy participants and applying operationalized diagnosis was included. Studies in somatically ill patients, N < 10 participants/group, and studies using consumer-devices were excluded. Activity-levels between groups were compared using random-effects models with standardized-mean-differences and several moderators were examined. In total, 34 studies (n = 1804 patients) were included. Patients had lower activity than controls [standardized mean difference (s.m.d.) = -0.78, 95% confidence interval (CI) -0.99 to -0.57]. Compared to controls, patients with unipolar and bipolar disorder had lower activity than controls whether in depressed (unipolar: s.m.d. = -0.82, 95% CI -1.07 to -0.56; bipolar: s.m.d. = -0.94, 95% CI -1.41 to -0.46), or remitted/euthymic mood (unipolar: s.m.d. = -0.28, 95% CI -0.56 to 0.0; bipolar: s.m.d. = -0.92, 95% CI -1.36 to -0.47). None of the examined moderators had any significant effect. To date, this is the largest meta-analysis on actigraphically measured slowing in mood disorders. They are associated with lower activity, even in the remitted/euthymic mood-state. Studying objective motor behavior via actigraphy holds promise for informing screening and staging of affective disorders.

Abstract
Background Motor abnormalities, such as psychomotor agitation and retardation, are widely recognized as core features of depression. However, it is not currently known if motor abnormalities connote risk for depression. Methods Using data from the Adolescent Brain Cognitive Development (ABCD) Study, a nationally representative sample of youth (n=10,835, 9-11 years old), the present paper examines whether motor abnormalities are associated with (a) depression symptoms in early adolescence, (b) familial risk for depression (familial risk loading), and (c) future depression symptoms. Motor abnormalities measures included traditional (DSM) motor signs such as psychomotor agitation and retardation as well as other motor domains such as developmental motor delays and dyscoordination. Results Traditional motor abnormalities were less prevalent (agitation=3.2%, retardation=0.3%) than non-traditional domains (delays=13.79%, coordination=35.5%) among adolescents. Motor dysfunction was associated with depression symptoms (Cohen's ds=0.02 to 0.12). Familial risk for depression was related to motor abnormalities (Cohen's ds=0.08 to 0.27), with the exception of motor retardation. Family vulnerability varied in sensitivity to depression risk (e.g., retardation: .53%; dyscoordination: 32.05%). Baseline endorsement of motor abnormalities predicted future depression symptoms at one-year follow-up. Conclusions These findings suggest that motor signs reflect a novel, promising future direction for examining vulnerability to depression risk in early adolescence.

Abstract
PURPOSE We investigate whether exposure to violence (ETV) during adolescence and emerging adulthood predicts engagement in chronic disease-related health risk behaviors years later among African Americans. DESIGN A longitudinal study following youth from mid-adolescence (mean age = 14.8 years) to young adulthood (mean age = 32.0 years). SETTING Flint, Michigan. SAMPLE Four hundred forty-two African American (96.2%) and mixed African American and White (3.8%) participants. MEASURES Outcomes were diet, smoking, drinking, and physical inactivity. Covariates were ETV, sex, mother's educational attainment, and substance use by siblings, peers, and parents. ANALYSIS Latent profile analysis was conducted to identify distinct patterns of adult health risk behaviors and assess the association of youth ETV and identified patterns. RESULTS Four latent profiles were identified: high substance use (n = 46; 10.41%), high overall risk (n = 71; 16.06%), low overall risk (n = 140; 31.67%) and inactive (n = 185, 41.86%). Relative to the low overall risk profile, ETV was associated with being in the high overall risk profile (b = 0.37, p = 0.04), but not other profiles. Female gender and higher maternal education were associated with being in the inactive profile compared to the low overall risk profile. Peer alcohol and tobacco use were associated with being in the high substance use profile. CONCLUSION ETV during adolescence and emerging adulthood increased the risk of engagement in multiple health risk behaviors later in life.

Abstract
The Research Domain Criteria (RDoC) and the Hierarchical Taxonomy of Psychopathology (HiTOP) represent major dimensional frameworks proposing two alternative approaches to accelerate progress in the way psychopathology is studied, classified, and treated. RDoC is a research framework rooted in neuroscience aiming to further the understanding of transdiagnostic biobehavioral systems underlying psychopathology and ultimately inform future classifications. HiTOP is a dimensional classification system, derived from the observed covariation among symptoms of psychopathology and maladaptive traits, which seeks to provide more informative research and treatment targets (i.e., dimensional constructs and clinical assessments) than traditional diagnostic categories. This article argues that the complementary strengths of RDoC and HiTOP can be leveraged in order to achieve their respective goals. RDoC's biobehavioral framework may help elucidate the underpinnings of the clinical dimensions included in HiTOP, whereas HiTOP may provide psychometrically robust clinical targets for RDoC-informed research. We present a comprehensive mapping between dimensions included in RDoC (constructs and subconstructs) and HiTOP (spectra and subfactors) based on narrative review of the empirical literature. The resulting RDoC-HiTOP interface sheds light on the biobehavioral correlates of clinical dimensions and provides a broad set of dimensional clinical targets for etiological and neuroscientific research. We conclude with future directions and practical recommendations for using this interface to advance clinical neuroscience and psychiatric nosology. Ultimately, we envision that this RDoC-HiTOP interface has the potential to inform the development of a unified, dimensional, and biobehaviorally-grounded psychiatric nosology.

Abstract
Transdiagnostic models of psychopathology suggest that disorders may share common features that could influence their severity. Attention problems and psychomotor restlessness are included in the diagnostic criteria for several disorders, including disorders on the internalizing spectrum, but their transdiagnostic significance has received little attention. The present study identifies patterns of attention problems and restlessness among youth with internalizing problems, in order to understand their clinical significance in terms of internalizing symptom severity and response to cognitive behavioral therapy (CBT). Participants were 142 adolescents age 11-18 clinically referred for mood and/or anxiety problems. Latent class analysis was used to identify patterns of self-reported attention problems and psychomotor restlessness, and classes were compared on internalizing, depression, and anxiety severity. Differences in treatment response were examined in a subset of youth (n = 82; age 14-18) who participated in group CBT. Youth in the Attention Problems class (42% of sample) and youth in the Restless class (15% of sample) endorsed significantly more internalizing, depression, and anxiety problems than youth with Low Symptoms of attention problems or psychomotor restlessness (43% of sample). Youth in the Restless class responded significantly better to CBT than youth in the Low Symptoms of attention problems or psychomotor restlessness class in terms of decrease in overall internalizing problems. Attention problems and psychomotor restlessness appear to be important transdiagnostic markers of severity across the internalizing spectrum; however, they do not limit the effectiveness of CBT and, in the case of psychomotor restlessness, may forecast a good treatment response.

Abstract
Abstract
Psychomotor slowing is frequently distressing patients with depression and schizophrenia. Increased neural activity within premotor cortices is linked to psychomotor slowing. This transdiagnostic study tested whether add-on inhibitory repetitive transcranial magnetic stimulation (rTMS) of the supplementary motor area (SMA) may alleviate psychomotor slowing. Forty-five patients with severe psychomotor slowing (26 psychosis, 19 major depression) were randomized in this transdiagnostic, double-blind, parallel-group, sham-controlled trial of 15 daily sessions of add-on rTMS over 3 weeks. Treatment arms included inhibitory 1 Hz stimulation of the SMA, facilitatory intermittent theta burst stimulation (iTBS) of the SMA, facilitatory 15 Hz stimulation of the left dorsolateral prefrontal cortex (DLPFC), and sham stimulation of the occipital cortex. The primary outcome was response (>30% reduction from baseline) according to the Salpêtrière Retardation Rating Scale (SRRS). Secondary outcomes were course of SRRS and further symptom rating scales. Last-observation carried forward method was applied to all subjects with baseline data. Response rates differed between protocols: 82% with inhibitory 1 Hz rTMS of the SMA, 0% with facilitatory iTBS of the SMA, 30% with sham, and 33% with 15 Hz DLPFC rTMS (χ 2 = 16.6, P < .001). Dropouts were similarly distributed across protocols. Response rates were similar in the completer analysis. This transdiagnostic trial of rTMS demonstrates that inhibitory SMA stimulation may ameliorate psychomotor slowing in severely ill patients. It further provides proof-of-concept that motor inhibition is linked to increased neural activity in the SMA because the inhibitory protocol performed best in reducing symptoms.

Abstract
Major depressive disorder (MDD) is a serious public health problem that has, at best, modest treatment response—potentially due to its heterogeneous clinical presentation. One way to parse the heterogeneity is to investigate the role of particular features of MDD, an endeavor that can also help identify novel and focal targets for treatment and prevention efforts. Our R01 focuses on the feature of psychomotor disturbance (e.g., psychomotor agitation (PmA) and retardation (PmR)), a particularly pernicious feature of MDD, that has not been examined extensively in MDD. Aim 1 is comparing three groups of individuals—those with current MDD (n = 100), remitted MDD (n = 100), and controls (n = 50)—on multiple measures of PmR and PmA (assessed both in the lab and in the subjects’ natural environment). Aim 2 is examining the structural (diffusion MRI) and functional (resting state fMRI) connectivity of motor circuitry of the three groups as well as the relation between motor circuitry and the proposed indicators of PmR and PmA. Aim 3 is following up with subjects three times over 18 months to evaluate whether motor symptoms change in tandem with overall depressive symptoms and functioning over time and/or whether baseline PmR/PmA predicts course of depression and functioning. Aim 3 is particularly clinically significant. Finding that motor functioning and overall depression severity co-vary over time, or that motor variables predict subsequent change in overall depression severity, would support the potential clinical utility of these novel, reliable, and easily administered motor assessments.

Abstract
Major depression consists of multiple phenotypic traits. Our objective was to characterize depressive phenotypes in the patient health questionnaire (PHQ)-9 using the Research Domain Criteria (RDoC) research framework. Cross-sectional data were examined from the 2013-2014 (N = 5397) and 2015-2016 (N = 5164) National Health and Nutrition Examination Survey, a large, nationally representative U.S. sample. Using both factor analysis and qualitative analysis in mapping scale items along RDoC domains, a four factor model was found to be theoretically appropriate and had an excellent model fit for the PHQ-9. The factor structure consisted of phenotypes describing Negative Valence Systems and Externalizing (anhedonia and depression), Negative Valence Systems and Internalizing (depression, guilt and self-harm), Arousal and Regulatory Systems (sleep, fatigue and appetite) and Cognitive and Sensorimotor Systems (concentration and psychomotor). High correlation between these phenotypes did indicate screening and monitoring for depression study population using a single depression score is likely useful in most circumstances. In multiple indicator multiple cause analysis, differences in the means of the phenotypic traits were found by age, race/ethnicity, sex, and number of comorbidities. Future research should explore whether phenotype expression derived from readily available self-rated depression scales can help to inform more personalized care.

Abstract
BACKGROUND African American youth are among those at greatest risk for experiencing violence victimization. Notably, the mortality rate of cervical cancer for African American women is also twice that of white women. To date, we know of no literature using longitudinal data to examine how violence victimization relates to Papanicolaou (Pap) smear results or cervical cancer in this population. Our study examines how violence victimization during adolescence (age 15 to 18) influences psychological distress, perceived social support, heavy substance abuse, and sexual risk behaviors during emerging adulthood (age 20 to 23), and subsequent Pap smear outcomes during young adulthood (age 29 to 32). METHOD This study is based on 12 waves of data collected in a longitudinal study of 360 African American women from mid-adolescence (ninth grade, mean age = 14.8 years) to young adulthood (mean age = 32.0 years). We used structural equation modeling analysis to examine the hypothesized model. RESULT Violence victimization during adolescence had a direct effect on decreased social support, increased psychological distress, and increased heavy cigarette use during emerging adulthood. Better social support was also associated with fewer sexual partners during emerging adulthood and lower odds of abnormal Pap smear results during young adulthood. The effect of violence victimization on abnormal Pap smear was mediated by social support. CONCLUSION Our results show that violence victimization during adolescence has long-term negative effects through multiple pathways that persist into adulthood. Our findings also suggest that social support may help to compensate against other risk factors. Interventions designed to address the perceived support may help victims cope with their experience.

Abstract
BACKGROUND AND OBJECTIVES Psychomotor restlessness and agitation (PMA) is a putatively important, yet understudied, psychopathologic correlate of smoking. The scant smoking research on PMA previously conducted has been narrow in scope and conducted among psychiatric patients. To examine the generalizability and relevance of PMA to smoking, this cross-sectional study investigated associations between PMA and a variety of smoking processes in a community sample. METHODS Participants in this study were non-treatment-seeking smokers (N = 254, ≥10 cig/day, M age = 44 years) from the community without an active mood disorder. At baseline, they completed a PMA symptom checklist, a composite depressive symptom index, and a battery of smoking questionnaires. RESULTS Linear regression models adjusting for depressive symptoms and demographics indicated that PMA level was positively associated with severity of nicotine withdrawal symptoms during prior quit attempts (β = .18, p < .05), anticipated likelihood of withdrawal in a future quit attempt (β = .19, p < .05), motivation to smoke for negative reinforcement (β = .14, p < .05), and smoking expectancies for negative reinforcement (β = .17, p < .05), negative consequences (β = .22, p < .01), and positive reinforcement (β = .14, p < .05). PMA was not significantly associated with smoking chronicity, frequency, or dependence severity. CONCLUSION AND SCIENTIFIC SIGNIFICANCE Smokers with elevated PMA appear to experience greater smoking-induced affect modulation and nicotine withdrawal than the average smoker, regardless of other depressive symptoms. Given that PMA differentiates a qualitatively unique profile of smoking characteristics, PMA warrants consideration in tobacco addiction research and practice.

FRAS1-related extracellular matrix 3 (FREM3) single-nucleotide polymorphism effects on gene expression, amygdala reactivity and perceptual processing speed: An accelerated aging pathway of depression risk. Front Psychol 2015; 6:1377. [PMID: 26441752 PMCID: PMC4584966 DOI: 10.3389/fpsyg.2015.01377] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2015] [Accepted: 08/27/2015] [Indexed: 12/24/2022] Open
Abstract
The A allele of the FRAS1-related extracellular matrix protein 3 (FREM3) rs7676614 single nucleotide polymorphism (SNP) was linked to major depressive disorder (MDD) in an early genome-wide association study (GWAS), and to symptoms of psychomotor retardation in a follow-up investigation. In line with significant overlap between age- and depression-related molecular pathways, parallel work has shown that FREM3 expression in postmortem human brain decreases with age. Here, we probe the effect of rs7676614 on amygdala reactivity and perceptual processing speed, both of which are altered in depression and aging. Amygdala reactivity was assessed using a face-matching BOLD fMRI paradigm in 365 Caucasian participants in the Duke Neurogenetics Study (DNS) (192 women, mean age 19.7 ± 1.2). Perceptual processing speed was indexed by reaction times in the same task and the Trail Making Test (TMT). The effect of rs7676614 on FREM3 mRNA brain expression levels was probed in a postmortem cohort of 169 Caucasian individuals (44 women, mean age 50.8 ± 14.9). The A allele of rs7676614 was associated with blunted amygdala reactivity to faces, slower reaction times in the face-matching condition (p < 0.04), as well as marginally slower performance on TMT Part B (p = 0.056). In the postmortem cohort, the T allele of rs6537170 (proxy for the rs7676614 A allele), was associated with trend-level reductions in gene expression in Brodmann areas 11 and 47 (p = 0.066), reminiscent of patterns characteristic of older age. The low-expressing allele of another FREM3 SNP (rs1391187) was similarly associated with reduced amygdala reactivity and slower TMT Part B speed, in addition to reduced BA47 activity and extraversion (p < 0.05). Together, these results suggest common genetic variation associated with reduced FREM3 expression may confer risk for a subtype of depression characterized by reduced reactivity to environmental stimuli and slower perceptual processing speed, possibly suggestive of accelerated aging.

Abstract
We review the conflicting results from imaging studies of dopamine transporter availability in depressed patients and also discuss the heterogeneity of the variables involved. Major depression includes diverse clinical manifestations and in recent years there has been an increasing interest in the identification of homogeneous phenotypes and different clinical subtypes of depression, e.g. anhedonic depression, retarded depression, etc. In addition, the use of different radioligands and imaging techniques, diverse rating scales, together with the lack of control of clinical variables (clinical course, recent or past use of substances of abuse, etc.) make it difficult to clearly identify neuronal regions or networks with consistently abnormal structures or functions in major depressive disorder. It is probably necessary to build a shared approach between clinicians and researchers in order to identify standardized procedures to better understand the role of the dopamine transporter in depression. We outline a list of major issues and also suggest some standardized procedures in collecting clinical and imaging data on major depressed patients. Our aim is to delineate a possible "modus operandi" that would be a proposal for neuroreceptor studies on major depression.

Abstract
Psychomotor retardation is a central feature of depression which includes motor and cognitive impairments. Effective management may be useful to improve the classification of depressive subtypes and treatment selection, as well as prediction of outcome in patients with depression. The aim of this paper was to review the current status of knowledge regarding psychomotor retardation in depression, in order to clarify its role in the diagnostic management of mood disorders. Retardation modifies all the actions of the individual, including motility, mental activity, and speech. Objective assessments can highlight the diagnostic importance of psychomotor retardation, especially in melancholic and bipolar depression. Psychomotor retardation is also related to depression severity and therapeutic change and could be considered a good criterion for the prediction of therapeutic effect. The neurobiological process underlying the inhibition of activity includes functional deficits in the prefrontal cortex and abnormalities in dopamine neurotransmission. Future investigations of psychomotor retardation should help improve the understanding of the pathophysiological mechanisms underlying mood disorders and contribute to improving their therapeutic management.

Abstract
This paper reviews two learning theory-based models of experiential contributions to depression: response contingent positive reinforcement and learned helplessness. The authors argue that these models connect to a phenomenon that may explain why symptoms of behavioral excess (e.g. rumination) often occur in depression that is otherwise marked by symptoms of behavioral deficit (e.g. anhedonia). Specifically, the authors illustrate that that concept of schedule strain (or low rates of response contingent reinforcement giving rise to low frequencies of behavior) unites these models. Depression is more likely, or more severe, when schedule strain conditions occur in situations containing reinforcers important to the individual and/or when they simultaneously occur in a number of situations. Conditions of schedule strain are known to give rise to adjunctive behaviors: apparently irrelevant, easy behaviors that deliver immediate reinforcement. This paper suggests that, for some depressed individuals, behavioral excess symptoms like rumination and overeating might serve adjunctive functions. Implications of this hypothesis are discussed.

Abstract
BACKGROUND Although techniques such as latent class analysis have been used to derive empirically based subtypes of depression in adult samples, there is limited information on subtypes of depression in youth. AIMS To identify empirically based subtypes of depression in a nationally representative sample of US adolescents, and to test the comparability of subtypes of depression in adolescents with those derived from a nationally representative sample of adults. METHOD Respondents included 912 adolescents and 805 adults with a 12-month major depressive disorder, selected from the National Comorbidity Survey Adolescent Supplement and the National Comorbidity Survey Replication samples respectively. Latent class analysis was used to identify subtypes of depression across samples. Sociodemographic and clinical correlates of derived subtypes were also examined to establish their validity. RESULTS Three subtypes of depression were identified among adolescents, whereas four subtypes were identified among adults. Two of these subtypes displayed similar diagnostic profiles across adolescent and adult samples (P = 0.43); these subtypes were labelled 'severe typical' (adults 45%, adolescents 35%) and 'atypical' (adults 16%, adolescents 26%). The latter subtype was characterised by increased appetite and weight gain. CONCLUSIONS The structure of depression observed in adolescents is highly similar to the structure observed in adults. Longitudinal research is necessary to evaluate the stability of these subtypes of depression across development.

Abstract
OBJECTIVE Major depressive disorder (MDD) with atypical features is characterized by mood reactivity, increased appetite/weight gain and hypersomnia. Since these characteristics may be associated with obesity and diabetes, we examined whether individuals with MDD with atypical features (MDD-AD) are more likely to exhibit cardiovascular disease than those with MDD without atypical features (MDD-NAD). METHODS Participants in the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of noninstitutionalized US adults, were categorized as having no lifetime depression diagnosis (n=34,979), MDD-NAD (n=4632) and MDD-AD (n=1063) and reported physician-confirmed specific cardiovascular diagnoses in the previous year. RESULTS Compared to individuals without depression, those with MDD had a 50% increased odds of any cardiovascular diagnosis (P<.0001) independent of sociodemographic factors. Adjusting for sociodemographic differences in MDD subgroups, MDD-AD (compared to MDD-NAD) was associated with 60% (P<.0001) and 43% (P<.005) increases in the odds of hypertension and any cardiovascular diagnosis, respectively. These latter associations were no longer significant after adjusting for body mass index and substance use. CONCLUSION Individuals with major depression are at increased risk of heart disease. Whereas major depression with atypical features is associated with certain cardiovascular risk factors, there is no greater risk of cardiovascular diagnoses.

Abstract
Despite the use of actigraphy in depression research, the association of depression ratings and quantitative motor activity remains controversial. In addition, the impact of recurring episodes on motor activity is uncertain. In 76 medicated inpatients with major depression (27 with a first episode, 49 with recurrent episodes), continuous wrist actigraphy for 24h and scores on the Hamilton Depression Rating Scale (HAMD) were obtained. In addition, 10 subjects of the sample wore the actigraph over a period of 5 days, in order to assess the reliability of a 1-day measurement. Activity levels were stable over 5 consecutive days. Actigraphic parameters did not differ between patients with a first or a recurrent episode, and quantitative motor activity failed to correlate with the HAMD total score. However, of the motor-related single items of the HAMD, the item activities was associated with motor activity parameters, while the items agitation and retardation were not. Actigraphy is consistent with clinical observation for the item activities. Expert raters may not correctly rate the motor aspects of retardation and agitation in major depression.

Abstract
BACKGROUND Depression with psychomotor agitation (PMA; "agitated depression") is a putative psychiatric phenotype that appears to associate with some forms of substance dependence. However, it is unclear whether such relationships extend across different substances and independent (I-MDE) versus substance-induced (SI-MDE) subtypes of major depressive episodes. METHOD We examined whether lifetime depression with (vs. without) PMA was associated with lifetime substance dependence across individuals with lifetime: (1) I-MDE only (n=575); and (2) SI-MDE only (n=1683). Data were pooled from several family and genetic studies of substance dependence in which participants received identical structured interviews to diagnose DSM-IV mental disorders. RESULTS In I-MDE, PMA was significantly associated with alcohol, cocaine, opioid, other drug (hallucinogen, inhalant, speed-ball), and sedative dependence. After controlling for demographic and clinical co-factors, PMA's relationship to dependence on opioids, other drugs, and sedatives remained significant, but not its relationship to alcohol or cocaine. In SI-MDE, PMA was significantly associated with alcohol, cocaine, opioid, and other drug dependence. After adjusting for co-factors, associations remained significant for dependence on cocaine and opioids, but not alcohol or other drugs. Relationships between PMA and opioid dependence were stronger in I-MDE than SI-MDE. Depression subtype (I-MDE vs. SI-MDE) did not moderate relations between PMA and non-opioid forms of substance dependence. CONCLUSIONS Agitated depression associates with certain forms of substance dependence, particularly opioid dependence. MDE subtype did not alter most PMA-dependence associations, which suggests that the mechanisms underlying this comorbidity are complex and potentially bidirectional.

Associations between subtypes of major depressive episodes and substance use disorders. Psychiatry Res 2011; 186:248-53.

Abstract
The goal of this study was to examine whether certain subtypes of major depressive episodes (MDEs)-defined by their particular constellations of symptoms-were more strongly associated with substance use disorders (SUDs), compared to other subtypes of MDEs. Participants were adults in the National Comorbidity Survey-Replication sample who met DSM criteria for at least one lifetime MDE (n=1829). Diagnostic assessments were conducted using structured interviews. The following MDE subtypes were examined: atypical, psychomotor agitation, psychomotor retardation, melancholic, and suicidal. The results indicated that: (1) suicidal MDEs were associated with increased risk for all SUDs; (2) melancholic MDEs were associated with increased risk for alcohol use disorders; and (3) psychomotor agitation was associated with increased risk for alcohol dependence. These associations did not differ significantly by gender. Adjusting for age, the severity of the MDE, the age of onset of the first MDE, and psychiatric comorbidity did not substantially change the results. Supplemental analyses examining only diagnoses that occurred in the year prior to the assessment demonstrated a similar pattern (with MDEs characterized by psychomotor agitation being associated with drug use disorders as well). Exploratory order of onset analyses indicated that participants with lifetime MDEs and SUDs tended to report an MDE onset prior to the SUD onset, and those who experienced a suicidal MDE at some time in their lives were particularly likely to have had their first MDE prior to developing a SUD. Therefore, risk for lifetime SUDs differs according to the particular set of symptoms experienced during MDEs.

Abstract
Previous studies have shown that both bipolar disorder (BPD) and psychomotor agitation (PMA) are associated with substance dependence. These two findings have yet to be integrated, despite evidence that PMA is closely linked with the bipolar spectrum. Accordingly, the current study examined whether BPD and PMA had unique or overlapping associations with substance dependence disorders. Participants were 2,300 individuals seeking outpatient psychiatric treatment. Before treatment, participants were assessed using structured clinical interviews, which yielded DSM-IV psychiatric diagnoses and clinical ratings of mood symptoms. Current PMA and lifetime BPD were present in 483 and 172 (bipolar I, n = 71; bipolar II, n = 101) participants, respectively. Current PMA and lifetime BPD each were associated with increased prevalence of lifetime nicotine, alcohol, and drug dependence (ORs >or= 1.52, ps <or= .0004). These associations remained significant when controlling for demographic characteristics and comorbid psychiatric disorders, except the link between agitation and alcohol dependence, which was reduced to a trend (p = .058). Although BPD and PMA were associated with each other, these two factors demonstrated unique, nonoverlapping relationships to nicotine, alcohol, and drug dependence. Individuals with both PMA and BPD exhibited especially high rates of comorbid substance dependence. The present results replicate and extend previous findings documenting the relations of BPD and PMA to substance dependence. BPD and PMA may represent independent psychopathological correlates of substance dependence. Future research should explore the theoretical and clinical significance of these potentially distinct relations to substance dependence.

Abstract
Evaluating whether certain subtypes of Major Depressive Disorder (MDD) are more strongly associated with Substance Use Disorders (SUDs) may help clarify reasons for MDD-SUD relations. Therefore, this study compared DSM-IV-defined non-atypical/non-melancholic depression (undifferentiated depression; n=365), atypical depression (n=117), melancholic depression (n=245), and atypical-melancholic depression (n=68) in the prevalence of current SUDs, while controlling for relevant demographic and clinical variables. Psychiatric outpatients with a current diagnosis of unipolar MDD were assessed using the Structured Clinical Interview for DSM-IV, supplemented by questions from the Schedule for Affective Disorders and Schizophrenia. Results showed that compared with patients with undifferentiated depression, melancholic patients had higher rates of current nicotine dependence (34% vs. 26%) and drug abuse/dependence (8% vs. 3%), Ps<0.05. These differences were explained by the association between specific melancholic features (marked psychomotor agitation and weight loss/decreased appetite) and nicotine and drug use disorders. Atypical depression, atypical-melancholic depression, and other subtype symptoms were not significantly associated with any SUDs. Although this study is limited by low prevalence of alcohol and drug use disorders, the present findings suggest that different symptomatic expressions of MDD differentially associate with some SUDs.
