The Relationship Between Family Functioning and Adolescent Depressive Symptoms: The Role of Emotional Clarity.

Emotion regulation has been implicated in the etiology of depression. A first step in adaptive emotion regulation involves emotional clarity, the ability to recognize and differentiate one's emotional experience. As family members are critical in facilitating emotional understanding and communication, we examined the impact of family functioning on adolescent emotional clarity and depressive symptoms. We followed 364 adolescents (ages 14-17; 52.5% female; 51.4 % Caucasian, 48.6% African American) and their mothers over 2 years (3 time points) and assessed emotional clarity, depressive symptoms, and adolescents' and mothers' reports of family functioning. Emotional clarity mediated the relationship between adolescents' reports of family functioning and depressive symptoms at all time points cross-sectionally, and according to mothers' reports of family functioning at Time 1 only. There was no evidence of longitudinal mediation for adolescents' or mothers' reports of family functioning. Thus, family functioning, emotional clarity, and depressive symptoms are strongly related constructs during various time points in adolescence, which has important implications for intervention, especially within the family unit.

Cognitive Attributions in Depression: Bridging the Gap between Research and Clinical Practice.

Individuals seeking treatment for depression often are struggling with maladaptive cognitions that impact how they view themselves and the world. Research on cognitive attributions that underlie depressed mood focuses on the phenomenon of negative cognitive style, in which depressed people tend to view undesirable occurrences in life as having internal, stable, and global causes. Based on research, clinicians have developed various techniques that seek to modify depressive attributions in order to alleviate symptoms of depression. In this article, the authors review the literature on attributions in depression, present clinically relevant interventions based on empirical support, provide case examples, and summarize future directions and recommendations for researchers and practitioners.

Early risk factors for psychopathology in offspring of parents with bipolar disorder: the role of obstetric complications and maternal comorbid anxiety.

OBJECTIVE: Offspring of parents with bipolar disorder (BD) are at increased risk for developing a range of psychiatric disorders. Although genetic factors clearly confer risk to offspring, environmental factors also play a role in increasing vulnerability. Such environmental factors may occur at the initial stages of development in the form of obstetric complications (OCs). The current investigation examined the relationship between OCs and the development of psychopathology in offspring at risk for BD and the influence of parental psychopathology in this relationship. METHODS: This cross-sectional study included 206 offspring of 119 parents with BD. Probit regression analyses examined associations between: (1) OC history and offspring psychopathology; and (2) maternal lifetime comorbid anxiety diagnoses and OCs in pregnancy/delivery with their offspring. Path analyses then tested whether OCs mediate the relationship between maternal comorbid anxiety disorders and offspring lifetime psychopathology. RESULTS: Results indicated a specific association between OCs, particularly delivery complications, and increased risk for offspring anxiety disorders. Data also showed a significant relationship between maternal anxiety disorder comorbidity and OCs. Finally, path analyses suggested that delivery complications act as a mediator in the relationship between comorbid maternal anxiety disorder and offspring anxiety disorder. CONCLUSIONS: Our findings lend support to the importance of identifying and reducing anxiety in pregnant woman with BD. The identification of OCs as early vulnerability factors for psychopathology in offspring at familial risk may also lead to earlier detection and intervention in these offspring.

Social Isolation-Mediated Exacerbation of Negative Affect in Young Drinkers during the COVID-19 Pandemic.

Emerging research on psychological adjustment during the COVID-19 outbreak has suggested that young people may be particularly vulnerable to increases in negative affect during the pandemic. However, the association between alcohol use in youth and change in negative affect during this unprecedented time is not clear. Using an online survey, this study obtained scores on negative affect (before and during the COVID-19 pandemic), pandemic-related stress, change in drinking frequency, and traits including resilience, impulsivity and anhedonia, from a sample of drinkers and non-drinkers, up to the age of 21. Young drinkers experienced a greater increase in negative affect during the pandemic compared to non-drinkers, and this differential rise in negative affect was mediated by the pandemic-related stress of social isolation. Young drinkers also experienced a decrease in alcohol use during the pandemic, but this was not associated with a change in negative affect. Interestingly, young drinkers with greater resilience and lower anhedonia reported less increase in negative affect during the COVID-19 pandemic. Taken together, these results show that the greater increase in negative affect that young drinkers experienced during the COVID-19 pandemic, compared to their non-drinking counterparts, was mediated by pandemic-related social isolation. Moreover, greater resilience and lower anhedonia may have served as protective factors for mitigating the social isolation-induced worsening of negative affect in young drinkers during the pandemic. These findings may inform future studies investigating potential indicators of maladaptive affective responses to public health crises in vulnerable adolescent populations.

Predictors of parental locus of control in mothers of pre- and early adolescents.

Parental locus of control refers to parents' perceived power and efficacy in child-rearing situations. This study explored parental locus of control and its correlates in 160 mothers of children ages 8 to 14 cross-sectionally and 1 year later. Maternal depression, maternal expressed emotion, and child internalizing and externalizing behavior were examined, along with a number of sociodemographic factors. Cross-sectional analyses indicated that external parental locus of control was associated with child externalizing behavior, maternal depression, less maternal education, lower income, and older maternal age. Longitudinal analyses showed that child age and externalizing behavior also predicted increases in external parental locus of control 1 year later. Finally, lower income and less parental perceived control predicted increases in child externalizing behavior over time.

Confirmatory factor analysis of the Coping Strategies Questionnaire-Revised for veterans with pain.

As the need for appropriate assessment and treatment of veterans with chronic pain continues to grow, it is important to ensure that the instruments we use to complete these assessments, such as the Coping Strategies Questionnaire-Revised (CSQ-R), are validated on this population. The purpose of the present study was to confirm the factor structure of the CSQ-R in veterans. Secondary analyses examined associations between various pain coping strategies and measures of mood and health functioning. Participants consisted of 281 veterans who were referred to and evaluated by a Psychology Pain Management Program in a northeastern Department of Veterans Affairs health care facility. Participants completed self-report questionnaires including the CSQ-R and measures of disability, mood, and health. Confirmatory factor analysis (CFA) compared the 6-factor solution to models identified in other studies. The CFA indicated that the 6-factor solution of the CSQ-R proposed by Riley and Robinson (1997) is valid and has the best fit of all models tested when used with veterans. The results of the secondary correlational analyses were consistent with previous research indicating that coping self-statements and ignoring pain are adaptive pain coping strategies. Our findings support the psychometric soundness of the 6-factor CSQ-R when used with veterans with chronic pain. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Anhedonia as a clinical correlate of inflammation in adolescents across psychiatric conditions.

Objectives: Peripheral inflammation has been associated with multiple psychiatric disorders, particularly with depression. However, findings remain inconsistent and unreproducible, most likely due to the disorder's heterogeneity in phenotypic presentation. Therefore, in the present study, in an effort to account for inter-individual differences in symptom severity, we utilised a dimensional approach to assess the relationships between a broad panel of inflammatory cytokines and key psychiatric symptoms (i.e. depression, anhedonia, anxiety, fatigue and suicidality) in adolescents across psychiatric disorders. We hypothesised that only anhedonia (reflecting deficits of reward function) will be associated with inflammation.Methods: Participants were 54 psychotropic medication-free adolescents with diverse psychiatric conditions and 22 healthy control (HC) adolescents, aged 12-20. We measured 41 cytokines after in vitro lipopolysaccharide stimulation. Mann-Whitney U and Spearman correlation tests examined group comparison and associations, respectively, while accounting for multiple comparisons and confounds, including depression severity adolescent.Results: There were no group differences in cytokine levels. However, as hypothesised, within the psychiatric group, only anhedonia was associated with 19 cytokines, including haematopoietic growth factors, chemokines, pro-inflammatory cytokines, and anti-inflammatory cytokines.Conclusions: Our findings suggest that general inflammation may induce reward dysfunction, which plays a salient role across psychiatric conditions, rather than be specific to one categorical psychiatric disorder.

A Double-Blind Placebo-Controlled Trial of Omega-3 Fatty Acids as a Monotherapy for Adolescent Depression.

OBJECTIVE: Reports are mixed on the efficacy of omega-3 fatty acids (O3FA) for the treatment of major depressive disorder (MDD), with only limited data in adolescents. The present trial aimed to investigate systematically the efficacy of O3FA as a monotherapy, compared to a placebo, in adolescents with MDD. Secondarily, we explored O3FA effects on anhedonia, irritability, and suicidality-all key features of adolescent MDD. METHODS: Fifty-one psychotropic medication-free adolescents with DSM-IV-TR diagnoses of MDD (aged 12-19 years; 57% female) were randomized to receive O3FA or a placebo for 10 weeks. Data were collected between January 2006 and June 2013. O3FA and a placebo were administered on a fixed-flexible dose titration schedule based on clinical response and side effects. The initial dose of 1.2 g/d was increased 0.6 g/d every 2 weeks, up to a maximum of 3.6 g/d. Clinician-rated and self-rated depression severity, along with treatment response, served as primary outcome measures. Additionally, we examined O3FA effects on depression-related symptoms, including anhedonia, irritability, and suicidality. Treatment differences were analyzed via intent-to-treat analyses. RESULTS: O3FA were not superior to a placebo on any clinical feature, including depression severity and levels of anhedonia, irritability, or suicidality. Additionally, response rates were comparable between treatment groups. Within-treatment analyses indicated that both treatments were associated with significant improvement in depression severity on self- (O3FA: t = -4.38, P < .001; placebo: t = -3.52, P = .002) and clinician (O3FA: t = -6.47, P < .001; placebo: t = -8.10, P < .001) ratings. CONCLUSIONS: In adolescents with MDD, O3FA do not appear to be superior to placebo. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00962598.

The role of lifetime anxiety history in the course of bipolar spectrum disorders.

Individuals with bipolar spectrum disorder (BSD) frequently meet criteria for comorbid anxiety disorders, and anxiety may be an important factor in the etiology and course of BSDs. The current study examined the association of lifetime anxiety disorders with prospective manic/hypomanic versus major depressive episodes. Participants were 244 young adults (aged 17-26) with milder forms of BSDs (i.e., bipolar-II, cyclothymia, BD-NOS). First, bivariate analyses assessed differences in baseline clinical characteristics between participants with and without DSM-IV anxiety diagnoses. Second, negative binomial regression analyses tested whether lifetime anxiety predicted number of manic/hypomanic or major depressive episodes developed during the study. Third, survival analyses evaluated whether lifetime anxiety predicted time to onset of manic/hypomanic and major depressive episodes. Results indicated that anxiety history was associated with greater illness severity at baseline. Over follow-up, anxiety history predicted fewer manic/hypomanic episodes, but did not predict number of major depressive episodes. Anxiety history also was associated with longer time to onset of manic/hypomanic episodes, but shorter time to onset of depressive episodes. Findings corroborate past studies implicating anxiety disorders as salient influences on the course of BSDs. Moreover, results extend prior research by indicating that anxiety disorders may be linked with reduced manic/hypomanic phases of illness.

Neural correlates of RDoC reward constructs in adolescents with diverse psychiatric symptoms: A Reward Flanker Task pilot study.

BACKGROUND: There has been growing interest under the Research Domain Criteria initiative to investigate behavioral constructs and their underlying neural circuitry. Abnormalities in reward processes are salient across psychiatric conditions and may precede future psychopathology in youth. However, the neural circuitry underlying such deficits has not been well defined. Therefore, in this pilot, we studied youth with diverse psychiatric symptoms and examined the neural underpinnings of reward anticipation, attainment, and positive prediction error (PPE, unexpected reward gain). Clinically, we focused on anhedonia, known to reflect deficits in reward function. METHODS: Twenty-two psychotropic medication-free youth, 16 with psychiatric symptoms, exhibiting a full range of anhedonia, were scanned during the Reward Flanker Task. Anhedonia severity was quantified using the Snaith-Hamilton Pleasure Scale. Functional magnetic resonance imaging analyses were false discovery rate corrected for multiple comparisons. RESULTS: Anticipation activated a broad network, including the medial frontal cortex and ventral striatum, while attainment activated memory and emotion-related regions such as the hippocampus and parahippocampal gyrus, but not the ventral striatum. PPE activated a right-dominant fronto-temporo-parietal network. Anhedonia was only correlated with activation of the right angular gyrus during anticipation and the left precuneus during PPE at an uncorrected threshold. LIMITATIONS: Findings are preliminary due to the small sample size. CONCLUSIONS: This pilot characterized the neural circuitry underlying different aspects of reward processing in youth with diverse psychiatric symptoms. These results highlight the complexity of the neural circuitry underlying reward anticipation, attainment, and PPE. Furthermore, this study underscores the importance of RDoC research in youth.

A pilot study of cortical glutathione in youth with depression.

AIM: This study used proton magnetic resonance spectroscopy (1H MRS) to measure in vivo brain glutathione (GSH) in adolescents with major depressive disorder (MDD), and explored the relationship between GSH and illness severity and chronicity. Secondarily, associations between GSH and anhedonia, a key symptom of MDD in adolescents, were investigated. METHODS: Occipital cortex GSH levels were obtained in 19 psychotropic medication-free adolescents with MDD (ages 12-21) and compared to those in eight healthy control adolescents. Correlations between GSH levels and anhedonia severity were examined both in the full participant sample and within the MDD group. Within the MDD group, correlations between GSH levels and illness severity and chronicity were assessed. RESULTS: Occipital GSH levels were lower in adolescents with MDD compared to controls, but did not correlate with anhedonia (either within the MDD group or the full sample), MDD severity, or onset. There were also no group differences in levels of total choline, creatine, and N-acetylaspartate - all neurometabolites that were simultaneously detected with 1H MRS. CONCLUSIONS: Although preliminary, findings add new data to support the role of oxidative stress in MDD and suggest that lower GSH may be a potential marker of MDD early on in the course of illness.

Aggression Protects Against the Onset of Major Depressive Episodes in Individuals With Bipolar Spectrum Disorder.

A growing body of research suggests that bipolar spectrum disorders (BSDs) are associated with high aggression. However, little research has prospectively examined how aggression may affect time to onset of hypomanic/manic versus major depressive episodes. In a longitudinal study, we tested the hypothesis that aggression would prospectively predict a shorter time to the onset of hypomanic/manic episodes and a longer time to the onset of major depressive episodes, based on the behavioral approach system theory of BSDs. Young adults (N = 120) diagnosed with cyclothymia, bipolar II disorder, or bipolar disorder not otherwise specified were followed every 4 months for an average of 3.55 years. Participants completed measures of depressive and manic symptoms, family history of mood disorder, impulsivity, and aggression at baseline and were followed prospectively with semistructured diagnostic interview assessments of hypomanic/manic and major depressive episodes and treatment seeking for mood problems. Cox proportional hazard regression analyses indicated that overall, physical, and verbal aggression predicted a longer time to major depressive episode onset, even after controlling for baseline depressive and manic symptoms, family history of mood disorder, treatment seeking for mood problems, and impulsivity. Aggression, however, did not significantly predict time to onset of hypomanic/manic episodes, controlling for the same covariates. The findings suggest that approach-related behaviors may be utilized to delay the onset of major depressive episodes among people with BSDs.

Co-occurring disorders of adolescents in primary care: closing the gaps.

The increasing prevalence of co-occurring mental health and substance use disorders in adolescents is a serious challenge for the primary care system. The needs of these youth continue to be underrecognized, poorly diagnosed, and inappropriately treated in primary care settings, which are often the first point of contact with the health provider system. This article highlights the need for changes at the clinical, organizational, and policy levels to create a system of care that can effectively identify, refer, treat, and coordinate the care for these adolescents and their families.

Role of Reward Sensitivity and Processing in Major Depressive and Bipolar Spectrum Disorders.

Since Costello's (1972) seminal Behavior Therapy article on loss of reinforcers or reinforcer effectiveness in depression, the role of reward sensitivity and processing in both depression and bipolar disorder has become a central area of investigation. In this article, we review the evidence for a model of reward sensitivity in mood disorders, with unipolar depression characterized by reward hyposensitivity and bipolar disorders by reward hypersensitivity. We address whether aberrant reward sensitivity and processing are correlates of, mood-independent traits of, vulnerabilities for, and/or predictors of the course of depression and bipolar spectrum disorders, covering evidence from self-report, behavioral, neurophysiological, and neural levels of analysis. We conclude that substantial evidence documents that blunted reward sensitivity and processing are involved in unipolar depression and heightened reward sensitivity and processing are characteristic of hypomania/mania. We further conclude that aberrant reward sensitivity has a trait component, but more research is needed to clearly demonstrate that reward hyposensitivity and hypersensitivity are vulnerabilities for depression and bipolar disorder, respectively. Moreover, additional research is needed to determine whether bipolar depression is similar to unipolar depression and characterized by reward hyposensitivity, or whether like bipolar hypomania/mania, it involves reward hypersensitivity.

Functional domains as correlates of suicidality among psychiatric inpatients.

BACKGROUND: Suicide remains poorly understood and unpredictable. Addressing this challenge, this study examined the independent contributions of several research domain criteria (RDoC) constructs in relation to suicidality in patients hospitalized for acute suicide risk. Specifically, we examined anhedonia, anxiety/entrapment, and attachment disturbances, reflecting disturbances in reward processes, negative valence systems, and social processes, respectively. METHODS: Anhedonia, anxiety, entrapment, and fearful attachment, were assessed quantitatively in 135 adults hospitalized for suicidality. Current suicidality and suicidal history were assessed with the Columbia Suicide Severity Rating Scale. Bivariate analyses (with significance threshold of p<.01 to account for multiple comparisons) and multivariate models examined relationships between symptom dimensions and severity of suicidal ideation (SI). We also assessed differences between patients with a history of suicide attempt and those who exhibited only suicidal ideations. RESULTS: Using bivariate analyses all symptoms except for fearful attachment correlated robustly with SI (r =.37-0.50, p<.001). However, when using multivariate analyses, only anhedonia (ß=.28, p=.01) and entrapment (ß=.19, p=.03) were independently associated with SI across the entire sample. No functional domain measures differed between patients with history of suicide attempt versus ideation only. LIMITATIONS: The reliance on self-report data and a cross-sectional design. CONCLUSIONS: Disturbances in reward and threat processing may represent independent factors in the development of suicidal ideation in this high suicide risk cohort. Future studies should assess their role as risk factors.

Decreased Anterior Cingulate Cortex γ-Aminobutyric Acid in Youth With Tourette's Disorder.

BACKGROUND: γ-Aminobutyric acid has been implicated in the pathophysiology of Tourette's disorder. The present study primarily sought to examine in vivo γ-aminobutyric acid levels in the anterior cingulate cortex in psychotropic medication-free adolescents and young adults. Secondarily, we sought to determine associations between γ-aminobutyric acid in the anterior cingulate cortex and measures of tic severity, tic-related impairment, and anxiety and depression symptoms. METHODS: γ-Aminobutyric acid levels were measured using proton magnetic resonance spectroscopy. Analysis of covariance compared γ-aminobutyric acid levels in 15 youth with Tourette's disorder (mean age = 15.0, S.D. = 2.7) and 36 healthy comparison subjects (mean age = 15.9, S.D. = 2.1). Within the Tourette disorder group, we examined correlations between γ-aminobutyric acid levels and tic severity and tic-related impairment, as well as anxiety and depression severity. RESULTS: Anterior cingulate cortex γ-aminobutyric acid levels were lower in participants with Tourette's disorder compared with control subjects. Within the Tourette disorder group, γ-aminobutyric acid levels did not correlate with any clinical measures. CONCLUSIONS: Our findings support a role for γ-aminobutyric acid in Tourette's disorder. Larger prospective studies will further elucidate this role.

A latent class analysis of parental bipolar disorder: Examining associations with offspring psychopathology.

Bipolar disorder (BD) is highly heterogeneous, and course variations are associated with patient outcomes. This diagnostic complexity challenges identification of patients in greatest need of intervention. Additionally, course variations have implications for offspring risk. First, latent class analysis (LCA) categorized parents with BD based on salient illness characteristics: BD type, onset age, polarity of index episode, pole of majority of episodes, rapid cycling, psychosis, anxiety comorbidity, and substance dependence. Fit indices favored three parental classes with some substantively meaningful patterns. Two classes, labeled "Earlier-Onset Bipolar-I" (EO-I) and "Earlier-Onset Bipolar-II" (EO-II), comprised parents who had a mean onset age in mid-adolescence, with EO-I primarily BD-I parents and EO-II entirely BD-II parents. The third class, labeled "Later-Onset BD" (LO) had an average onset age in adulthood. Classes also varied on probability of anxiety comorbidity, substance dependence, psychosis, rapid cycling, and pole of majority of episodes. Second, we examined rates of disorders in offspring (ages 4-33, Mage=13.46) based on parental latent class membership. Differences emerged for offspring anxiety disorders only such that offspring of EO-I and EO-II parents had higher rates, compared to offspring of LO parents, particularly for daughters. Findings may enhance understanding of BD and its nosology.

Family functioning in the context of parental bipolar disorder: associations with offspring age, sex, and psychopathology.

Previous research has shown that families with a parent who has bipolar disorder (BD) may experience family functioning difficulties. However, the association between family functioning and psychopathology among offspring of parents with BD, and offspring characteristics that may moderate this association, remains poorly understood. This study examined the cross-sectional associations between family functioning (cohesion, expressiveness, and conflict) and psychopathology in 117 offspring (ages 5-18) of 75 parents with BD. We also examined whether age and sex differences moderated these associations. We measured offspring psychopathology by examining current dimensional symptoms and DSM-IV emotional and behavioral disorders. Correlational analyses indicated that higher family conflict and lower cohesion were associated with higher internalizing and externalizing symptoms in offspring. Lower family cohesion was also associated with current offspring mood disorders. Moderation analyses indicated, first, that the link between lower family cohesion and internalizing symptoms was stronger for younger offspring compared to older offspring. Second, higher family conflict and current mood disorder were associated in younger males but not in older males or in females. Results remained the same after controlling for parental anxiety or substance use disorder comorbidity. Our study highlights the importance of accounting for family functioning when working with offspring at risk for BD, while also recognizing that the connections between family functioning and offspring outcomes are complex and differ based on offspring sex and developmental stage.

Impacts of sea level rise and climate change on coastal plant species in the central California coast.

Local increases in sea level caused by global climate change pose a significant threat to the persistence of many coastal plant species through exacerbating inundation, flooding, and erosion. In addition to sea level rise (SLR), climate changes in the form of air temperature and precipitation regimes will also alter habitats of coastal plant species. Although numerous studies have analyzed the effect of climate change on future habitats through species distribution models (SDMs), none have incorporated the threat of exposure to SLR. We developed a model that quantified the effect of both SLR and climate change on habitat for 88 rare coastal plant species in San Luis Obispo, Santa Barbara, and Ventura Counties, California, USA (an area of 23,948 km(2)). Our SLR model projects that by the year 2100, 60 of the 88 species will be threatened by SLR. We found that the probability of being threatened by SLR strongly correlates with a species' area, elevation, and distance from the coast, and that 10 species could lose their entire current habitat in the study region. We modeled the habitat suitability of these 10 species under future climate using a species distribution model (SDM). Our SDM projects that 4 of the 10 species will lose all suitable current habitats in the region as a result of climate change. While SLR accounts for up to 9.2 km(2) loss in habitat, climate change accounts for habitat suitability changes ranging from a loss of 1,439 km(2) for one species to a gain of 9,795 km(2) for another species. For three species, SLR is projected to reduce future suitable area by as much as 28% of total area. This suggests that while SLR poses a higher risk, climate changes in precipitation and air temperature represents a lesser known but potentially larger risk and a small cumulative effect from both.

Enhancing maternal depression recognition in health care settings: a review of strategies to improve detection, reduce barriers, and reach mothers in need.

Maternal depression is a major public health concern in the United States affecting mothers, children, and families. Many mothers experience depression, and exposure to maternal depression can put children at increased risk for psychopathology and poor psychosocial development. Early recognition of maternal depression is a critical step in promoting healthy development and preventing adverse outcomes in children and families. In this review, we examine some of the major barriers that mothers face in seeking help for depression; discuss optimal settings in which to implement maternal depression screening; review available depression screening tools for identifying mothers in need of care; discuss steps providers can take after screening; examine barriers to screening; and present information about promising initiatives developed to address these barriers.
