Predictors of treatment efficacy in a clinical trial of three psychosocial treatments for adolescent depression

What CBT Modules Work Best for Whom? Identifying Subgroups of Depressed Youths by Their Differential Response to Specific Modules

Prior research suggests that the effects of specific cognitive-behavioral therapy (CBT) modules on symptom outcomes can be estimated. We conducted a study utilizing idiographic and nomothetic methods to clarify which CBT modules are most effective for youth depression, and for whom they are most effective. Thirty-five youths received modular CBT for depression. Interrupted time series models estimated whether the introduction of each module was associated with changes in internalizing symptoms, whereby significant symptom reduction would suggest a therapeutic response to the module. Regression models were used to explore whether participant characteristics predicted subgroups of youths based on their estimated response to certain types (e.g., cognitive) of modules, and whether group membership was associated with posttreatment outcomes. Thirty youths (86%) had at least one module associated with a significant change in internalizing symptoms from premodule delivery to postmodule delivery. The specific modules associated with these changes varied across youths. Behavioral activation was most frequently associated with symptom decreases (34% of youths). No participant characteristics predicted estimated response to module type, and group membership was not significantly associated with posttreatment outcomes. Youths display highly heterogeneous responses to treatment modules, indicating multiple pathways to symptom improvement for depressed youths.

A comparison of the effectiveness of cognitive behavioural interventions based on delivery features for elevated symptoms of depression in adolescents: A systematic review

Background

Depression is a public health problem and common amongst adolescents. Cognitive behavioural therapy (CBT) is widely used to treat adolescent depression but existing research does not provide clear conclusions regarding the relative effectiveness of different delivery modalities.

Objectives

The primary aim is to estimate the relative efficacy of different modes of CBT delivery compared with each other and control conditions for reducing depressive symptoms in adolescents. The secondary aim is to compare the different modes of delivery with regard to intervention completion/attrition (a proxy for intervention acceptability).

Search Methods

The Cochrane Depression, Anxiety and Neurosis Clinical Trials Register was searched in April 2020. MEDLINE, PsycInfo, EMBASE, four other electronic databases, the CENTRAL trial registry, Google Scholar and Google were searched in November 2020, together with reference checking, citation searching and hand-searching of two databases.

Selection Criteria

Randomised controlled trials (RCTs) of CBT interventions (irrespective of delivery mode) to reduce symptoms of depression in young people aged 10-19 years with clinically relevant symptoms or diagnosis of depression were included.

Data Collection and Analysis

Screening and data extraction were completed by two authors independently, with discrepancies addressed by a third author. CBT interventions were categorised as follows: group CBT, individual CBT, remote CBT, guided self-help, and unguided self-help. Effect on depressive symptom score was estimated across validated self-report measures using Hedges' g standardised mean difference. Acceptability was estimated based on loss to follow-up as an odds ratio. Treatment rankings were developed using the surface under the cumulative ranking curve (SUCRA). Pairwise meta-analyses were conducted using random effects models where there were two or more head-to-head trials. Network analyses were conducted using random effects models.

Main Results

Sixty-eight studies were included in the review. The mean age of participants ranged from 10 to 19.5 years, and on average 60% of participants were female. The majority of studies were conducted in schools (28) or universities (6); other settings included primary care, clinical settings and the home. The number of CBT sessions ranged from 1 to 16, the frequency of delivery from once every 2 weeks to twice a week and the duration of each session from 20 min to 2 h. The risk of bias was low across all domains for 23 studies, 24 studies had some concerns and the remaining 21 were assessed to be at high risk of bias. Sixty-two RCTs (representing 6435 participants) were included in the pairwise and network meta-analyses for post-intervention depressive symptom score at post-intervention. All pre-specified treatment and control categories were represented by at least one RCT. Although most CBT approaches, except remote CBT, demonstrated superiority over no intervention, no approaches performed clearly better than or equivalent to another. The highest and lowest ranking interventions were guided self-help (SUCRA 83%) and unguided self-help (SUCRA 51%), respectively (very low certainty in treatment ranking). Nineteen RCTs (3260 participants) were included in the pairwise and network meta-analyses for 6 to 12 month follow-up depressive symptom score. Neither guided self-help nor remote CBT were evaluated in the RCTs for this time point. Effects were generally attenuated for 6- to 12-month outcomes compared to posttest. No interventions demonstrated superiority to no intervention, although unguided self-help and group CBT both demonstrated superiority compared to TAU. No CBT approach demonstrated clear superiority over another. The highest and lowest ranking approaches were unguided self-help and individual CBT, respectively. Sixty-two RCTs (7347 participants) were included in the pairwise and network meta-analyses for intervention acceptability. All pre-specified treatment and control categories were represented by at least one RCT. Although point estimates tended to favour no intervention, no active treatments were clearly inferior. No CBT approach demonstrated clear superiority over another. The highest and lowest ranking active interventions were individual CBT and group CBT respectively. Pairwise meta-analytic findings were similar to those of the network meta-analysis for all analyses. There may be age-based subgroup effects on post-intervention depressive symptoms. Using the no intervention control group as the reference, the magnitudes of effects appear to be larger for the oldest age categories compared to the other subgroups for each given comparison. However, they were generally less precise and formal testing only indicated a significant difference for group CBT. Findings were robust to pre-specified sensitivity analyses separating out the type of placebo and excluding cluster-RCTs, as well as an additional analysis excluding studies where we had imputed standard deviations.

Authors' Conclusions

At posttreatment, all active treatments (group CBT, individual CBT, guided self-help, and unguided self-help) except for remote CBT were more effective than no treatment. Guided self-help was the most highly ranked intervention but only evaluated in trials with the oldest adolescents (16-19 years). Moreover, the studies of guided self-help vary in the type and amount of therapist support provided and longer-term results are needed to determine whether effects persist. The magnitude of effects was generally attenuated for 6- to 12-month outcomes. Although unguided self-help was the lowest-ranked active intervention at post-intervention, it was the highest ranked at follow-up. This suggests the need for further research into whether interventions with self-directed elements enable young people to maintain effects by continuing or revisiting the intervention independently, and whether therapist support would improve long-term outcomes. There was no clear evidence that any active treatments were more acceptable to participants than any others. The relative effectiveness of intervention delivery modes must be taken into account in the context of the needs and preferences of individual young people, particularly as the differences between effect sizes were relatively small. Further research into the type and amount of therapist support that is most acceptable to young people and most cost-effective would be particularly useful.

Systemic therapy in children and adolescents with mental disorders: a systematic review and meta-analysis

BACKGROUND

Systemic therapy (ST) is a psychotherapeutic intervention in complex human systems (both psychological and interpersonal). Cognitive behavioural therapy (CBT) is an established treatment for children and adolescents with mental disorders. As methodologically rigorous systematic reviews on ST in this population are lacking, we conducted a systematic review and meta-analysis to compare the benefit and harm of ST (and ST as an add-on to CBT) with CBT in children and adolescents with mental disorders.

METHODS

We searched MEDLINE, Embase, PsycINFO and other sources for randomised controlled trials in 14 mental disorder classes for the above comparisons in respect of effects on patient-relevant outcomes (search date: 7/2022). Where possible, meta-analyses were performed and results were graded into 3 different evidence categories: "proof", "indication", or "hint" (or none of these categories). PRISMA standards were followed.

RESULTS

Fifteen studies in 5 mental disorder classes with usable data were identified. 2079 patients (mean age: 10 to 19 years) were analysed. 12/15 studies and 29/30 outcomes showed a high risk of bias. In 2 classes, statistically significant and clinically relevant effects in favour of ST were found, supporting the conclusion of a hint of greater benefit of ST for mental and behavioural disorders due to psychoactive substance use and of ST as an add-on to CBT for obsessive-compulsive disorders. In 2 other classes (eating disorders; hyperkinetic disorders), there was no evidence of greater benefit or harm of ST. For affective disorders, a statistically significant effect to the disadvantage of ST was found for 1 outcome, supporting the conclusion of a hint of lesser benefit of ST.

CONCLUSIONS

Our results show a hint of greater benefit of ST (or ST as an add-on to CBT) compared with CBT for 2 mental disorder classes in children and adolescents (mental and behavioural disorders due to psychoactive substance use, obsessive compulsive disorders). Given the importance of CBT as a control intervention, ST can therefore be considered a beneficial treatment option for children and adolescents with certain mental disorders. Limitations include an overall high risk of bias of studies and outcomes and a lack of data for several disorders.

Family-Based Interventions for Youth Depression: Meta-Analysis of Randomized Clinical Trials

Youth depression is an impairing pediatric condition for which psychotherapy effects are modest. Can outcomes be improved by treatments that address the family context, as proposed in practice parameters of the American Academy of Child and Adolescent Psychiatry? To find out, we searched five decades of research for randomized controlled trials testing family-based interventions; 11 trials were found for ages 4-18 years. Using robust variance estimation, we obtained estimates of effect size (ES) and tested candidate moderators that might explain variation in ES. Overall pooled ES of the studies was 0.33 at posttreatment, similar to that reported for all youth depression treatments in three prior meta-analyses (i.e., 0.36, 0.30, and 0.29), but higher for adolescents (ages ≥ 13, 0.50) than children (0.04). Taken together, our findings do not show superior outcomes for family-based interventions, and raise questions about how much confidence can be placed in the evidence base to date. The small number of relevant studies in more than five decades, together with the publication bias and risk of bias concerns, highlights the need for more trials testing family-based treatment, and for pre-registered reports, publicly-available preprints, and other mechanisms for improving the dissemination of completed research.

Research Review: The internalizing paradox - youth anxiety and depression symptoms, psychotherapy outcomes, and implications for research and practice

BACKGROUND

Youth anxiety and depression have long been combined within the empirically derived internalizing syndrome. The two conditions show substantial comorbidity, symptom co-occurrence, and overlap in treatment procedures, but paradoxically diverge in psychotherapy outcomes: strong, positive effects for anxiety and weak effects for depression.

METHODS

Drawing on recent research, we examine candidate explanations for this paradox to help identify strategies for addressing it by improving outcomes for youth depression.

RESULTS

Candidate explanations include that youth depression, compared with youth anxiety, has more varied comorbidities and more heterogeneous symptom combinations, has greater uncertainty regarding mediators and mechanisms of change, is treated with more complex and potentially confusing protocols, and has characteristics that may impede client engagement. Candidate strategies for shrinking the psychotherapy effectiveness gap include personalizing through transdiagnostic modular treatment, simplifying therapy by focusing on empirically supported principles of change, developing effective strategies for engaging family members as intervention allies, using shared decision-making to inform clinical decisions and boost client engagement, capitalizing on youth-friendly technological advances, and shortening and digitizing treatments to enhance their accessibility and appeal.

CONCLUSIONS

Recent advances suggest explanations for the internalizing paradox, which in turn suggest strategies for shrinking the youth anxiety-depression psychotherapy outcome gap; these form an agenda for a promising new era of research.

Disrupting Maternal Transmission of Depression: Using Integrative Data Analysis (IDA) to Examine Indirect Effects of the Family Check-Up (FCU) Across Three Randomized Trials

Maternal depression is a well-established risk factor for the development of depression in offspring. As such, reducing maternal depression may be key to effective prevention efforts to reduce offspring's depression. Based on the broad risk represented by maternal depression, examining cross-over effects of parent-focused interventions on maternal depression is important. The present study examined improvements in maternal depression as a mediator of the long-term effects of the Family Check-Up (FCU) prevention program on youth depression across three randomized controlled trials. The FCU is a family-focused intervention originally designed to reduce youth problem behaviors, particularly conduct problems and substance use, but has also been found to have cross-over effects on other youth problem behaviors, including internalizing symptoms. We utilized integrative data analysis that allows for powerful tests of prevention effects across trials, specifically moderated nonlinear factor analysis, to integrate data across three trials: one trial initiated in early childhood and two in early adolescence. Using a latent growth modeling approach, we first examined direct effects of the FCU on changes in maternal depression. Then we examined the mediating effect of maternal depression on changes in both parent and youth reports of youth depression. A significant intervention effect on maternal depression was observed across the three trials, with the FCU predicting improvements in maternal depression. In turn, such improvements predicted a reduction in the growth in both parent and youth reports of youth depressive symptoms across 10 years post baseline. These results demonstrate the utility in addressing cross-over effects of family-focused interventions in reducing the long-term development of depression in youth through mediating pathways.

Functional Family Therapy for families of youth (age 11-18) with behaviour problems: A systematic review and meta-analysis

Background

Functional Family Therapy (FFT) is a short-term family-based intervention for youth with behaviour problems. FFT has been widely implemented in the USA and other high-income countries. It is often described as an evidence-based program with consistent, positive effects.

Objectives

We aimed to synthesise the best available data to assess the effectiveness of FFT for families of youth with behaviour problems.

Search Methods

Searches were performed in 2013-2014 and August 2020. We searched 22 bibliographic databases (including PsycINFO, ERIC, MEDLINE, Science Direct, Sociological Abstracts, Social Services Abstracts, World CAT dissertations and theses, and the Web of Science Core Collection), as well as government policy databanks and professional websites. Reference lists of articles were examined, and experts were contacted to search for missing information.

Selection Criteria

We included randomised controlled trials (RCTs) and quasi-experimental designs (QEDs) with parallel cohorts and statistical controls for between-group differences at baseline. Participants were families of young people aged 11-18 with behaviour problems. FFT programmes were compared with usual services, alternative treatment, and no treatment. There were no publication, geographic, or language restrictions.

Data Collection and Analysis

Two reviewers independently screened 1039 titles and abstracts, read all available study reports, assessed study eligibility, and extracted data onto structured electronic forms. We assessed risks of bias (ROB) using modified versions of the Cochrane ROB tool and the What Works Clearinghouse standards. Where possible, we used random effects models with inverse variance weights to pool results across studies. We used odds ratios for dichotomous outcomes and standardised mean differences for continuous outcomes. We used Hedges g to adjust for small sample sizes. We assessed the heterogeneity of effects with χ 2 and I 2. We produced separate forest plots for conceptually distinct outcomes and for different endpoints (<9, 9-14, 15-23, and 24-42 months after referral). We grouped studies by study design (RCT or QED), and then assessed differences between these two subgroups of studies with χ 2 tests. We generated robust variance estimates, using correlated effects (CE) models with small sample corrections to synthesise all available outcome data. Exploratory CE analyses assessed potential moderators of effects within these domains. We used GRADE guidelines to assess the certainty of evidence on six primary outcomes at 1 year after referral.

Main Results

Twenty studies (14 RCTs and 6 QEDs) met our inclusion criteria. Fifteen of these studies provided some valid data for meta-analysis; these studies included 10,980 families in relevant FFT and comparison groups. All included studies had high risks of bias on at least one indicator. Half of the studies had high risks of bias on baseline equivalence, support for intent-to-treat analysis, selective reporting, and conflicts of interest. Fifteen studies had incomplete reporting of outcomes and endpoints. Using the GRADE rubric, we found that the certainty of evidence for FFT was very low for all of our primary outcomes. Using pairwise meta-analysis, we found no evidence of effects of FFT compared with other active treatments on any primary or secondary outcomes. Primary outcomes were: recidivism, out-of-home placement, internalising behaviour problems, external behaviour problems, self-reported delinquency, and drug or alcohol use. Secondary outcomes were: peer relations and prosocial behaviour, youth self esteem, parent symptoms and behaviour, family functioning, school attendance, and school performance. There were few studies in the pairwise meta-analysis (k < 7) and little heterogeneity of effects across studies in most of these analyses. There were few differences between effect estimates obtained in RCTs versus QEDs. More comprehensive CE models showed positive results of FFT in some domains and negative results in others, but these effects were small (standardised mean difference [SMD] <|0.20|) and not significantly different from no effect with one exception: Two studies found positive effects of FFT on youth substance abuse and two studies found null results in this domain, and the overall effect estimate for this outcome was statistically different from zero. Over all outcomes (15 studies and 293 effect sizes), small positive effects were detected (SMD = 0.19, SE = 0.09), but these were not significantly different from zero effect. Prediction intervals showed that future FFT evaluations are likely to produce a wide range of results, including moderate negative effects and strong positive results (-0.37 to 0.75).

Authors’ Conclusions

Results of 10 RCTs and five QEDs show that FFT does not produce consistent benefits or harms for youth with behavioural problems and their families. The positive or negative direction of results is inconsistent within and across studies. Most outcomes are not fully reported, the quality of available evidence is suboptimal, and the certainty of this evidence is very low. Overall estimates of effects of FFT may be inflated, due to selective reporting and publication biases.

Aromatherapy for the brain: Lavender's healing effect on epilepsy, depression, anxiety, migraine, and Alzheimer's disease: A review article

Neurological diseases affect the nervous system, including the brain, spinal cord, cranial nerves, nerve roots, autonomic nervous system, neuromuscular junctions, and muscles. Herbal medicine has long been used to cure these diseases. One of these plants is lavender, which is composed of various compounds, including terpenes, such as linalool, limonene, triterpenes, linalyl acetate, alcohols, ketones, polyphenols, coumarins, cineole, and flavonoids. In this review, the literature was searched using scientific search engines and databases (Google Scholar, Science Direct, Scopus, and PubMed) for papers published between 1982 and 2020 via keywords, including review, lavender, and neurological disorders. This plant exerts its healing effect on many diseases, such as anxiety and depression through an inhibitory effect on GABA. The anti-inflammatory effects of this plant have also been documented. It improves depression by regulating glutamate receptors and inhibiting calcium channels and serotonergic factors, such as SERT. Its antiepileptic mechanism is due to an increase in the inhibitory effect of GABA and potassium current and a decrease in sodium current. Therefore, many vegetable oils are also used in herbal medicine. In this review, the healing effect of lavender on several neurological disorders, including epilepsy, depression, anxiety, migraine, and Alzheimer's disease was investigated. All findings strongly support the traditional uses of lavender. More clinical studies are needed to investigate the effect of the plants' pharmacological active constituents on the treatment of life-threatening diseases in humans. The limitations of this study are the low quality and the limited number of clinical studies. Different administration methods of lavender are one of the limitations of this review.

Event-related Oscillations to Emotional Faces are Related to a History of Internalizing Disorders

Event-related oscillations (EROs) may represent sensitive biomarkers or endophenotypes for disorders that underlie risk behaviors such as suicidal thoughts and actions. In this study, young adults of American Indian (AI) (n = 821) and Mexican American (MA) (n = 721) ancestry (age 18-30 yrs) were clinically assessed for internalizing and externalizing disorders, and an internalizing scale was generated by extracting core diagnostic items from 6 lifetime DSM5-compatible diagnoses (social phobia, panic disorder, agoraphobia, obsessive compulsive disorder, post-traumatic stress disorder, major depressive episode) and symptoms of suicidality. EROs were generated to sad, happy and neutral faces, and energy and phase locking of delta ERO oscillations were assessed in frontal areas. An increase in delta ERO energy was found in the frontal lead (FZ) following presentation of the sad facial expressions in those with a history of 10 or more internalizing symptoms compared to those with no symptoms. Increases in delta ERO energy in FZ were also associated with a diagnosis of major depressive disorder (MDD), but not with anxiety disorders or antisocial personality disorder/conduct disorders (ASP). Major depression was also associated with increases in cross-cortical phase-locking (FZ-PZ). A decrease in the percentage of correctly identified neutral faces also was seen among those with 10 or more internalizing symptoms compared to those without internalizing symptoms, and in those with anxiety disorders, but not in those with ASP or MDD as compared to their controls. These findings suggest ERO measures may represent important potential biomarkers of depressive disorders as well as risk indicators for suicidal behaviors.

Treatment-resistant depression in children and adolescents

Major depressive disorder (MDD) in children and adolescents is a significant health problem, causing profound impairments in social, academic, and family functioning and substantial morbidity and mortality. Up to 15% of children and adolescents suffer from MDD, and a proportion, around 30 to 40% of them, failed to respond to initial selective serotonin reuptake inhibitor (SSRI) treatment. The only evidence-based recommendation is medication switching to another SSRI and augmentation with cognitive behavioral therapy. Newly developing treatment, including ketamine, transcranial magnetic stimulation, psychotherapy other than cognitive behavioral therapy, and combined pharmacotherapy with other interventions, requires further longitudinal controlled trials regarding efficacy and safety in this vulnerable population.

Predictors of treatment non-response for depression in a sample of female adolescents with risk-taking and self-injurious behavior - A one year follow-up

OBJECTIVE

Depressive disorders (DD) are highly prevalent among adolescents. While up to 60 % do not respond to treatment, evidence on predictors of treatment non-response in this age group is mixed, impeding meaningful clinical implications. Drawing on a consecutive clinical cohort of adolescents with risk taking and self-injurious behavior, the present study aimed to identify predictors of treatment non-response for female DD in a naturalistic one year follow-up.

METHODS

The sample comprised female adolescents with verified DD (n = 152). Patients underwent assessments at baseline (T0) and follow-up (T1). Sociodemographic factors (e.g., age), clinical measures (e.g., symptom severity, trauma), and treatment variables (e.g. number of psychotherapy sessions), were analyzed as potential predictors of treatment non-response in unadjusted analyses and analyses adjusting for treatment intensity and age at baseline. Treatment response was defined based on not fulfilling formal diagnosis for DD at follow-up (52.3 %; n = 80) or the 50 % decrease in self-reported depressive symptoms (21.1 %; n = 32) from T0 to T1.

RESULTS

Greater depressive and overall symptom severity, greater frequency of self-injuries, history of suicide attempts and history of childhood trauma at T0 were robustly associated with treatment non-response based on diagnostic interviews. Only a lower number of siblings was robustly associated with treatment non-response based on self-reports.

LIMITATIONS

Findings may not generalize to other treatment settings.

CONCLUSION

Collectively, our results highlight overall symptom severity as significant predictor of treatment non-response in female adolescents with depression. Methodological differences (interviews versus self-reports) and potential implications from these findings for clinical practice are discussed.

The impact of maternal depression on child mental health treatment and models for integrating care: a systematic review

Maternal depression negatively impacts child mental health and is a well-known risk factor for child psychopathology. However, maternal depression treatment and child mental health treatment are rarely integrated. The purpose of this review was to assess the impact of maternal depression on child mental health treatment, including (1) how treatment of maternal depression affects child mental health outcomes, (2) the impact of maternal depression on children receiving mental health care, and (3) emerging models that address maternal depression in primary-care pediatrics and child mental health settings. A systematic literature review was conducted using PubMed and PsycInfo. Initial search yielded 224 records, and after exclusion, 29 papers were reviewed. Effective treatment of maternal depression is associated with a significant decrease in child psychiatric symptoms. Maternal depression negatively affects child mental health treatment in that there is a high rate of untreated mental illness among mothers of psychiatrically ill children, and maternal depression impedes effective child mental health treatment. Current models to address maternal depression in child settings include screening in pediatric primary care, psychotherapy for depressed mothers of psychiatrically ill children, and emerging models that integrate maternal and child mental health treatment. Effective treatment of maternal depression significantly improves child mental health and should be better integrated into child treatment. Opportunities to improve care include more robust screening for parental mental illness, supports to refer parents to psychiatric care, and on-site services for parents. Such interventions hold promise, but require significant support from a multidisciplinary team.

Predictors of outcome after a time-limited psychosocial intervention for adolescent depression

Research on the predictors of outcome for early, community-based, and time-limited interventions targeted for clinical depression in adolescents is still scarce. We examined the role of demographic, psychosocial, and clinical variables as predictors of outcome in a trial conducted in Finnish school health and welfare services to identify factors associating to symptom reduction and remission after a brief depression treatment. A total of 55 12–16-year-olds with mild to moderate depression received six sessions of either interpersonal counseling for adolescents (IPC-A) or brief psychosocial support (BPS). Both interventions resulted in clinical improvement at end of treatment and 3- and 6-month follow-ups. Main outcome measures were self-rated BDI-21 and clinician-rated Adolescent Depression Rating Scale (ADRSc). Latent change score (LCS) models were used to identify predictors of change in depressive symptom scores and clinical remission at end of treatment and 3- and 6-month follow-ups over the combined brief intervention group. Symptom improvement was predicted by younger age and having a close relationship with parents. Both symptom improvement and clinical remission were predicted by male gender, not having comorbid anxiety disorder, and not having sleep difficulties. Our results add to knowledge on factors associating with good treatment outcome after a brief community intervention for adolescent depression. Brief depression interventions may be useful and feasible especially for treatment of mild and moderate depression among younger adolescents and boys, on the other hand clinicians may need to cautiously examine sleep problems and anxiety comorbidity as markers of the need for longer treatment.

Neonatal D-fenfluramine treatment promotes long-term behavioral changes in adult mice

Serotonin exerts a significant role in the mammalian central nervous system embryogenesis and brain ontogeny. Therefore, we investigate the effect of neonatal treatment of d-fenfluramine (d-FEN), a serotonin (5-HT) releaser, on the behavioral expression of adult male Swiss mice. For this purpose, we divided pregnant female Swiss mice into two groups (n = 6 each and ~35 g). Their offspring were treated with d-FEN (3 mg/kg, s.c.) from postnatal days (PND) 5 to 20. At PND 21, one male puppy of each litter was euthanized; the midbrain and the hippocampus were dissected for RNA analysis. At PND 70, the male offspring underwent a behavioral assessment in the open field, elevated plus-maze, light-dark box, tail suspension, and rotarod test. The programmed animals had a decrease in 5HT1a, serotonin transporter (SERT), and brain-derived neurotrophic factor (BDNF) expression in the mesencephalic raphe region. Alternatively, there was a reduction only in the tryptophan hydroxylase (TPH2) and BDNF expression in the hippocampus. In the light-dark box test, offspring of the treated group had higher latency to light and less time on the light side than the control. Also, it was observed less time of immobility in the tail suspension test. We also observed low motor skill learning in the rotarod test. These findings suggest that programming with d-FEN during the neonatal period alters a mesencephalic and hippocampal serotonergic system, promoting anxiety, antidepressant behavior, low coordination, and motor learning in adults.

Higher socioeconomic status and less parental psychopathology improve prognosis in youths with bipolar disorder

BACKGROUND

To identify prospectively ascertained individual and family factors that are associated with improvement in Bipolar Disorder (BD) among youths who initially presented with poor course.

METHODS

82 youths with BD with persistent poor mood symptomatology ("predominantly ill course") were compared to 70 youths with BD who at intake had poor course, but showed improvement during the follow-up ("ill with improving course"), (ages 12.3 ± 3.3, vs. 11.7 ± 3.3 years old, at intake). Improvement was measured by the percentage of time euthymic during a mean follow-up of 12.8 years. Youths and parents were interviewed to assess psychopathology, functioning, treatment, and familial functioning and psychopathology.

RESULTS

Compared to the ill group, since intake, the improving group showed significantly lower subthreshold depression and hypo/mania, Attention Deficit Hyperactivity Disorder, and Disruptive Behavior Disorders. Parental Socioeconomic Status (SES) remained unchanged over time in the ill group, but progressively increased in the improving group. Importantly, the change in SES predated the improvement in the mood trajectory. The most influential variables that predicted improvement were higher SES, and absence of parental BD and Substance Use Disorder (SUD). Parental SUD also negatively affected the parental SES, which was directly associated with worse mood course.

LIMITATIONS

Predominantly self-reported White samples may limit generalizability; other factors potentially associated with outcome (e.g., treatment adherence), were not ascertained.

CONCLUSIONS

In addition to treating mood/comorbid psychopathology in symptomatic BD youths, to improve their prognosis, it is crucial to address their parent's BD and SUD and promote parental education/employment.

Predictors, Moderators, and Mediators Associated With Treatment Outcome in Randomized Clinical Trials Among Adolescents With Depression: A Scoping Review

Importance

The application of precision medicine principles for the treatment of depressive disorders in adolescents requires an examination of the variables associated with depression outcomes in randomized clinical trials (RCTs).

Objective

To describe predictors, moderators, and mediators associated with outcomes in RCTs for the treatment of depressive disorders in adolescents.

Evidence Review

A scoping review of RCTs for the treatment of depression in adolescents was conducted. Databases searched included MEDLINE, Embase, APA PsycInfo, and CINAHL. Included publications tested predictors, moderators, and/or mediators associated with depression symptom outcomes (eg, symptom reduction, response, remission) in RCTs pertaining to the treatment of adolescents, ages 13 to 17 years. Predictors were defined as variables that were associated with depression outcomes, independent of treatment group. Moderators were defined as baseline variables that were associated with differential outcomes between treatment groups. Mediators were defined by a formal mediation analysis. In duplicate, variables were extracted and coded with respect to analysis type (univariable or multivariable), statistical significance, direction of effect size, reporting of a priori hypotheses, and adjustment for multiple comparisons. Aggregated results were summarized by variable domain and RCT sample.

Findings

Eighty-one articles reporting on variables associated with outcomes across 33 RCTs were identified, including studies of biological (10 RCTs), psychosocial (18 RCTs), and combined (4 RCTs) treatments as well as a service delivery model (1 RCT). Fifty-three variable domains were tested as baseline predictors of depression outcome, 41 as moderators, 19 as postbaseline predictors, and 5 as mediators. Variable domains that were reported as significant in at least 3 RCTs included age, sex/gender, baseline depression severity, early response to treatment, sleep changes, parent-child conflict, overall psychopathology, suicidal ideation, hopelessness, functional impairment, attendance at therapy sessions, and history of trauma. Two publications reported a priori hypotheses and adjustment for multiple comparisons, both finding that baseline depression severity and family conflict were associated with poorer outcomes.

Conclusions and Relevance

This review identified commonly researched variables requiring more scrutiny as well as underresearched variables to inform future study designs. Further efforts to discover predictors, moderators, and mediators associated with treatment response have great potential to optimize care for adolescents with depression.

"Third-wave" cognitive and behavioral therapies and the emergence of a process-based approach to intervention in psychiatry

For decades, cognitive and behavioral therapies (CBTs) have been tested in randomized controlled trials for specific psychiatric syndromes that were assumed to represent expressions of latent diseases. Although these protocols were more effective as compared to psychological control conditions, placebo treatments, and even active pharmacotherapies, further advancement in efficacy and dissemination has been inhibited by a failure to focus on processes of change. This picture appears now to be evolving, due both to a collapse of the idea that mental disorders can be classified into distinct, discrete categories, and to the more central attention given to processes of change in newer, so-called "third-wave" CBTs. Here we review the context for this historic progress and evaluate the impact of these newer methods and models, not as protocols for treating syndromes, but as ways of targeting an expanded range of processes of change. Five key features of "third-wave" therapies are underlined: a focus on context and function; the view that new models and methods should build on other strands of CBT; a focus on broad and flexible repertoires vs. an approach to signs and symptoms; applying processes to the clinician, not just the client; and expanding into more complex issues historically more characteristic of humanistic, existential, analytic, or system-oriented approaches. We argue that these newer methods can be considered in the context of an idiographic approach to process-based functional analysis. Psychological processes of change can be organized into six dimensions: cognition, affect, attention, self, motivation and overt behavior. Several important processes of change combine two or more of these dimensions. Tailoring intervention strategies to target the appropriate processes in a given individual would be a major advance in psychiatry and an important step toward precision mental health care.

"Nothing to Lose, Absolutely Everything to Gain": Patient and Caregiver Expectations and Subjective Outcomes of Deep Brain Stimulation for Treatment-Resistant Depression

Background: How "success" is defined in clinical trials of deep brain stimulation (DBS) for refractory psychiatric conditions has come into question. Standard quantitative psychopathology measures are unable to capture all changes experienced by patients and may not reflect subjective beliefs about the benefit derived. The decision to undergo DBS for treatment-resistant depression (TRD) is often made in the context of high desperation and hopelessness that can challenge the informed consent process. Partners and family can observe important changes in DBS patients and play a key role in the recovery process. Their perspectives, however, have not been investigated in research to-date. The aim of this study was to qualitatively examine patient and caregivers' understanding of DBS for TRD, their expectations of life with DBS, and how these compare with actual experiences and outcomes. Methods: A prospective qualitative design was adopted. Semi-structured interviews were conducted with participants (six patients, five caregivers) before DBS-implantation and 9-months after stimulation initiation. All patients were enrolled in a clinical trial of DBS of the bed nucleus of the stria terminalis. Interviews were thematically analyzed with data saturation achieved at both timepoints. Results: Two primary themes identified were: (1) anticipated vs. actual outcomes, and (2) trial decision-making and knowledge. The decision to undergo DBS was driven by the intolerability of life with severe depression coupled with the exhaustion of all available treatment options. Participants had greater awareness of surgical risks compared with stimulation-related risks. With DBS, patients described cognitive, emotional, behavioral and physical experiences associated with the stimulation, some of which were unexpected. Participants felt life with DBS was like "a roller coaster ride"-with positive, yet unsustained, mood states experienced. Many were surprised by the lengthy process of establishing optimum stimulation settings and felt the intervention was still a "work in progress." Conclusion: These findings support existing recommendations for iterative informed consent procedures in clinical trials involving long-term implantation of neurotechnology. These rich and descriptive findings hold value for researchers, clinicians, and individuals and families considering DBS. Narrative accounts capture patient and family needs and should routinely be collected to guide patient-centered approaches to DBS interventions.

Moderators and Predictors of Response After 36 Weeks of Treatment in the Treatment for Adolescents with Depression Study (TADS)

This study investigated pretreatment variables associated with depression severity in adolescents following maintenance treatment for major depressive disorder (MDD). Data was derived from the Treatment for Adolescents with Depression Study (TADS). Participants received one of three treatments: cognitive behavioral therapy (CBT), fluoxetine (FLX), or combined CBT and fluoxetine (COMB). Participants received 12 weeks of acute treatment, 6 weeks of consolidation treatment, and 18 weeks of maintenance treatment (N = 327, M age = 14.62 yrs). Outcome was measured by the Children's Depression Rating Scale-Revised. Results showed adolescents with shorter depressive episodes, better global functioning, less suicidal ideation, better health/social functioning, and greater expectancy of positive treatment response were more likely to have lower depression severity following 36 weeks of treatment, regardless of modality. Adolescents with lower initial depression demonstrated lower depression severity if treated with CBT. FLX was more effective in reducing depression severity in adolescents with severe baseline depression than for those with mild or moderate depression. Adolescents with higher family incomes were more likely to have lower depression severity if they received CBT only. In conclusion, adolescents with shorter depressive episodes, better health, social, and global functioning, less suicidal ideation, and greater expectancy for treatment at baseline respond equally well to CBT, fluoxetine, and combined treatment. Adolescents who are more severely depressed at baseline may have a better treatment response if they are treated with FLX; whereas adolescents of higher income are more likely to have a better response if they receive CBT only.

Psychological Treatments for Depression in Adolescents: More Than Three Decades Later

Depression is a common and impairing disorder which is a serious public health problem. For some individuals, depression has a chronic course and is recurrent, particularly when its onset is during adolescence. The purpose of the current paper was to review the clinical trials conducted between 1980 and 2020 in adolescents with a primary diagnosis of a depressive disorder, excluding indicated prevention trials for depressive symptomatology. Cognitive behavioral therapy (CBT) is the pre-eminent treatment and is well established from an evidence-based treatment perspective. The body of research on the remaining treatments is smaller and the status of these treatments is varied: interpersonal therapy (IPT) is well established; family therapy (FT) is possibly effective; and short-term psychoanalytic therapy (PT) is experimental treatment. Implementation of the two treatments that work well-CBT and IPT-has more support when provided individually as compared to in groups. Research on depression treatments has been expanding through using transdiagnostic and modular protocols, implementation through information and communication technologies, and indicated prevention programs. Despite significant progress, however, questions remain regarding the rate of non-response to treatment, the fading of specific treatment effects over time, and the contribution of parental involvement in therapy.

McGrath J. Co-morbidity between mood and anxiety disorders: A systematic review and meta-analysis

There is consistent evidence that mood disorders often co-occur with anxiety disorders, however, the strength of the association of these two broad groups of disorders has been challenging to summarize across different studies. The aim was to conduct a meta-analysis of publications reporting on the pairwise comorbidity between mood and anxiety disorders after sorting into comparable study types. We searched MEDLINE, Embase, CINAHL, Web of Science, and the grey literature for publications between 1980 and 2017 regardless of geographical locations and languages. We meta-analyzed estimates from original articles after sorting by: (a) broad or narrow diagnostic criteria, (b) study time-frame, and (c) estimates with or without covariate adjustments. Over 43 000 unique studies were identified through electronic searches, of which 391 were selected for full-text review. Finally, 171 studies were eligible for inclusion, including 53 articles from additional snowball searching. In general, regardless of variations in diagnosis type, study time-frame, temporal order, or use of adjustments, there was substantial comorbidity between mood and anxiety disorders. Based on the entire 90 separate meta-analyses, the median OR was 6.1 (range 1.5-18.7). Of these estimates, all 90 were above 1, and 87 were significantly greater than 1 (i.e., the 95% confidence intervals did not include 1). Fourteen of the 90 pooled estimates had ORs that were greater than 10. This systematic review found robust and consistent evidence of comorbidity between broadly defined mood and anxiety disorders. Clinicians should be vigilant for the prompt identification and treatment of this common type of comorbidity.

International consensus on a standard set of outcome measures for child and youth anxiety, depression, obsessive-compulsive disorder, and post-traumatic stress disorder

A major barrier to improving care effectiveness for mental health is a lack of consensus on outcomes measurement. The International Consortium for Health Outcomes Measurement (ICHOM) has already developed a consensus-based standard set of outcomes for anxiety and depression in adults (including the Patient Health Questionnaire-9, the Generalised Anxiety Disorder 7-item Scale, and the WHO Disability Schedule). This Position Paper reports on recommendations specifically for anxiety, depression, obsessive-compulsive disorder, and post-traumatic stress disorder in children and young people aged between 6 and 24 years. An international ICHOM working group of 27 clinical, research, and lived experience experts formed a consensus through teleconferences, an exercise using an adapted Delphi technique (a method for reaching group consensus), and iterative anonymous voting, supported by sequential research inputs. A systematic scoping review identified 70 possible outcomes and 107 relevant measurement instruments. Measures were appraised for their feasibility in routine practice (ie, brevity, free availability, validation in children and young people, and language translation) and psychometric performance (ie, validity, reliability, and sensitivity to change). The final standard set recommends tracking symptoms, suicidal thoughts and behaviour, and functioning as a minimum through seven primarily patient-reported outcome measures: the Revised Children's Anxiety and Depression Scale, the Obsessive Compulsive Inventory for Children, the Children's Revised Impact of Events Scale, the Columbia Suicide Severity Rating Scale, the KIDSCREEN-10, the Children's Global Assessment Scale, and the Child Anxiety Life Interference Scale. The set's recommendations were validated through a feedback survey involving 487 participants across 45 countries. The set should be used alongside the anxiety and depression standard set for adults with clinicians selecting age-appropriate measures.

A multidimensional investigation of anxiety sensitivity and depression outcomes in cognitive-behavioral group therapy

We examined how anxiety sensitivity - the fear of symptoms of anxiety due to their perceived harmful effects - and gender are associated with treatment trajectory and outcomes in a large outpatient sample (N = 278) who received 14-weeks of cognitive-behavioral group therapy (CBGT) for depression. Three dimensions of anxiety sensitivity (cognitive, physical, and social concerns) and depression were assessed at pre-treatment, and the latter was assessed weekly during treatment. Latent growth curve models supported a link between cognitive concerns (fears of losing control over thoughts) and greater improvement in depression near the end of treatment (i.e., weeks 10-14); gender did not moderate trajectory. Gender (i.e., identifying as a woman) and greater physical concerns (fears of physical consequences of arousal symptoms) were associated with completion of < 8 sessions. Results suggest that those with more cognitive concerns might require greater time in treatment and/or benefit most from the focus on maladaptive assumptions and core beliefs in later CBGT sessions. Future research, including investigation of intervening variables, may elucidate the mechanisms through which greater physical concerns and gender are associated with treatment non-completion. Results supported differential associations of anxiety sensitivity dimensions with depression treatment outcomes, though further research attention is needed.

Parent functioning and child psychotherapy outcomes: Predicting outcomes in usual care

OBJECTIVE

The purpose of this study was (1) to examine whether three domains of a parent's functioning-parent distress, interpersonal relationships, and social role performance-changed over the course of their child's treatment, (2) to examine how these factors as measured at intake predicted youth progress in psychotherapy, and (3) to examine whether changes in these parent factors over the course of youth psychotherapy were associated with changes in youth symptoms.

METHOD

Participants were 339 youth, ages 4-17 and their parents from a community outpatient treatment setting undergoing usual care. Parent and child outcomes were examined across five time points over the course of child treatment. Hierarchical linear modeling was used to examine the relationship between parent domains and youth progress in therapy.

RESULTS

Results suggested that parent domains significantly predicted their child's symptoms at intake as well as change in psychotherapy. In addition, parent domains improved over the course of youth treatment and the progression of these changes was related to the progression of changes in youth scores across the course of treatment.

CONCLUSIONS

The results of this study highlight the important relationship between youth and parent functioning in the context of treatment of youth mental health issues.

The therapeutic relationship in Cognitive Behaviour Therapy with depressed adolescents: A qualitative study of good-outcome cases

OBJECTIVES

This paper aimed to explore client experiences of the therapeutic relationship among adolescents with good outcomes after receiving Cognitive Behaviour Therapy (CBT) for moderate to severe depression.

DESIGN

This was a qualitative study employing Interpretative Phenomenological Analysis (IPA).

METHODS

As part of a randomized clinical trial, 77 adolescents with moderate to severe depression were interviewed using a semi-structured interview, which was audio-recorded. Five of these interviews, with adolescents aged 14-18 years who completed CBT and had good outcomes, were purposively sampled and analysed using IPA.

RESULTS

The findings indicated that a positive therapeutic relationship was fostered with therapists who respected the adolescents' autonomy and sense of individuality, while offering experiences of emotional closeness and connection. This was achieved by balancing the dual roles of being 'friendly' and affable, with being a 'professional expert' thereby embodying a collaborative and egalitarian approach.

CONCLUSIONS

The therapeutic relationship in CBT can help to motivate adolescents to engage with cognitively and emotionally challenging tasks. By providing an understanding of what helps and hinders the development of a positive therapeutic relationship, the current findings offer important insight into how therapists can foster positive relationships with depressed adolescents. This knowledge will make it more likely that adolescents will engage in the treatment process and in turn experience greater therapeutic gains.

PRACTITIONER POINTS

Offers a detailed phenomenological analysis of what fostered a positive therapeutic relationship in good outcome CBT, and what was experienced as harmful from the adolescents' perspective. Provides support that the therapeutic relationship is crucial in CBT; a respectful and understanding relationship provides a platform for the adolescent to carry out CBT activities and tasks.

The Association Between Parental Depression and Child Psychosocial Intervention Outcomes: Directions for Future Research

Recent studies suggest that parental depressive symptoms may affect a child's ability to benefit from interventions for anxiety and depression. This article reviews the current literature, suggesting that, when parents experience current depressive symptoms, children are less likely to benefit from psychosocial interventions for anxiety and depression. Opportunities for future research are discussed, including moderators and mechanisms of the association between parental depressive symptoms and child intervention outcomes.

Hopelessness and its correlates with clinical outcomes in an outpatient setting

INTRODUCTION

This study examined whether patients with hopelessness and those without may significantly differ regarding their main presentations and clinical course in a large Italian population.

METHODS

The recruited sample included 583 currently euthymic outpatients with major affective disorders. The Beck Hopelessness Scale (BHS) assessed hopelessness using a cutoff score of 9 or higher. Participants were categorized based on the presence/absence of hopelessness. A binary logistic regression analysis -accounting for age and gender and considering history of psychotherapy, emotional/physical abuse, depressive symptoms, Toronto Alexithymia Scale (TAS) total score, difficulties identifying and communicating feelings as potential predictors- was carried out in order to detect the variables associated with hopelessness.

RESULTS

Individuals with hopelessness, compared to those without, were more likely to be older (p=0.005), females (p=0.01), to have a unipolar depressive disorder (p≤0.05), be prescribed antidepressants and psychotherapy in the past (p=0.001 and p≤0.05). Moreover, individuals with hopelessness scored higher on the Montgomery-Asberg Depression Rating Scale (p≤0.05) and on the emotional (p=<0.001), physical abuse (p≤0.01) and physical neglect (p≤0.05) subscales of the Childhood Trauma Questionnaire - Short form, and reported more difficulties identifying (p≤0.001) and communicating feelings (p≤0.001) than those without hopelessness. The multivariate analysis showed that having difficulties identifying feelings is independently associated with hopelessness.

DISCUSSION

These findings indicate that individuals with difficulties identifying feelings are at higher risk of hopelessness and of negative outcomes. Further studies need to explore the impact of alexithymia on hopelessness and clinical outcomes in the lifetime illness course.

Meta-Analysis: 13-Year Follow-up of Psychotherapy Effects on Youth Depression

OBJECTIVE

Youth depression is a debilitating condition that constitutes a major public health concern. A 2006 meta-analysis found modest benefits for psychotherapy versus control. Has 13 more years of research improved that picture? We sought to find out.

METHOD

We searched PubMed, PsychINFO, and Dissertation Abstracts International for 1960 to 2017, identifying 655 randomized, English-language psychotherapy trials for individuals aged 4 to 18 years. Of these, 55 assessed psychotherapy versus control for youth depression with outcome measures administered to both treatment and control conditions at post (κ = 53) and/or follow-up (κ = 32). Twelve study and outcome characteristics were extracted, and effect sizes were calculated for all psychotherapy versus control comparisons. Using a three-level random-effects model, we obtained an overall estimate of the psychotherapy versus control difference while accounting for the dependency among effect sizes. We then fitted a three-level mixed-effects model to identify moderators that might explain variation in effect size within and between studies.

RESULTS

The overall effect size (g) was 0.36 at posttreatment and 0.21 at follow-up (averaging 42 weeks after posttreatment). Three moderator effects were identified: effects were significantly larger for interpersonal therapy than for cognitive behavioral therapy, for youth self-reported outcomes than parent-reports, and for comparisons with inactive control conditions (eg, waitlist) than active controls (eg, usual care). Effects showed specificity, with significantly smaller effects for anxiety and externalizing behavior outcomes than for depression measures.

CONCLUSION

Youth depression psychotherapy effects are modest, with no significant change over the past 13 years. The findings highlight the need for treatment development and research to improve both immediate and longer-term benefits.

Predicting Patterns of Treatment Response and Outcome for Adolescents Who Are Suicidal and Depressed

OBJECTIVE

Although several treatments have been shown to be effective in treatment of youth suicidal thoughts and behaviors (STBs), there is a pressing need to account for the substantial variation in adolescents' response to and outcomes from these treatments.

METHOD

Secondary analyses of data from a 16-week randomized trial of Attachment-Based Family Therapy (ABFT) and Family-Enhanced NonDirective Supportive Therapy (FE-NST) identified distinct classes of adolescents' treatment response. Established risk factors for STBs, along with treatment condition and sociodemographic variables, were then tested as predictors of class membership.

RESULTS

Three patterns of adolescents' treatment response and outcome were identified: a) nonresponders (15.8%), b) good responders (57.5%), and c) partial responders (26.7%). After controlling for initial symptom severity, nonresponders were more likely to have higher levels of nonsuicidal self-injury and pessimism and were more likely to meet diagnostic criteria for major depressive disorder (MDD) than good or partial responders. Partial responders were more likely than good responders to meet criteria for MDD and to have higher perceived burdensomeness.

CONCLUSION

Although most adolescents showed significant symptom reductions with both treatments, adolescents with higher pretreatment levels of pessimism, MDD, nonsuicidal self-injury, and perceived burdensomeness were less likely to show an optimal pattern of treatment benefit. The findings point to heterogeneity in treatment response that may require adapting treatments for adolescents with these pretreatment profiles.

Parental Depressive Symptoms as a Predictor of Outcome in the Treatment of Child Depression

Child depression is an impairing condition for which psychotherapies have shown modest effects. Parental depression is a risk factor for development of child depression and might also be negatively associated with child depression treatment outcomes. To explore this possibility, we analyzed data from a study in which children were treated for depression after parental depressive symptoms had been assessed at baseline. Among children treated for depression in a randomized controlled trial, we identified 31 who had child- and parent-report pre- and post-treatment data on child symptoms and parent-report of pre-treatment parental depressive symptoms. Children were aged 8-13, 77% boys, and 52% Caucasian, 13% African-American, 6% Latino, and 29% multi-racial. Analyses focused on differences in trajectories of change (across weekly measurements), and post-treatment symptoms among children whose parents did (n = 12) versus did not (n = 19) have elevated depressive symptoms at baseline. Growth curve analyses showed markedly different trajectories of change for the two groups, by both child-report (p = 0.03) and parent-report (p = 0.03) measures: children of parents with less severe depression showed steep symptom declines, but children of parents with more severe depression showed flat trajectories with little change in symptoms over time. ANCOVAs showed lower post-treatment child symptoms for children of parents with less severe depression versus parents with more severe depression (p = 0.05 by child report, p = 0.01 by parent report). Parental depressive symptoms predict child symptom trajectories and poorer child treatment response, and may need to be addressed in treatment.

Reduced Reward Responsiveness Predicts Change in Depressive Symptoms in Anxious Children and Adolescents Following Treatment

Objectives: Reduced reward responsiveness, as measured by the event-related potential (ERP) component, the reward positivity (RewP), has been shown to play a role in the development of internalizing disorders, but implications for treatment remain unclear. In adult patients with anxiety and/or depression, reduced RewP has emerged as a predictor of greater change in symptoms following cognitive behavior therapy (CBT) or selective serotonin reuptake inhibitor (SSRI) treatment. The objectives of this preliminary study were to extend these findings to children and adolescents with anxiety disorders by evaluating RewP to reward as a predictor of change in anxiety severity or depressive symptoms following treatment with CBT or SSRI and to explore whether RewP differentially predicts response to one type of treatment. Methods: Patients (7-19 years old) with social and/or generalized anxiety disorder (N = 27) completed baseline measures of anxiety severity and depressive symptoms, as well as an ERP monetary reward anticipation and feedback task. RewP was measured in response to reward and breaking even feedback. Patients were then randomly assigned to CBT or SSRI treatment, and completed measures of anxiety and depressive symptom severity at the last treatment session. Results: Reduced reward responsiveness, as measured by RewP to rewards, predicted greater change in depressive symptoms following treatment, adjusting for baseline symptoms, age, and RewP to breaking even. RewP was not a significant predictor of change in anxiety symptoms. Although preliminary, exploratory analyses suggested that among anxious youth, RewP specifically predicted change in depressive symptoms following CBT, rather than SSRI. Conclusion: Results provide preliminary support for the utility of ERP measures of reward responsiveness in predicting treatment response in youth. With further research and standardization, ERP assessments could potentially be implemented in clinical settings to inform prognosis and treatment planning for youth with internalizing disorders.

Estimating patient-specific treatment advantages in the 'Treatment for Adolescents with Depression Study'

The 'Treatment for Adolescents with Depression Study' (TADS, ClinicalTrials.gov, identifier: NCT00006286) was a cornerstone, randomized controlled trial evaluating the effectiveness of standard treatment options for major depression in adolescents. Whereas previous TADS analyses examined primarily effect modifications of treatment-placebo differences by various patient characteristics, less is known about the modification of inter-treatment differences, and hence, patient characteristics that might guide treatment selection. We sought to fill this gap by estimating patient-specific inter-treatment differences as a function of patients' baseline characteristics. We did so by applying the 'model-based random forest', a recently-introduced machine learning-based method for evaluating effect heterogeneity that allows for the estimation of patient-specific treatment effects as a function of arbitrary baseline characteristics. Treatment conditions were cognitive-behavioural therapy (CBT) alone, fluoxetine (FLX) alone, and the combination of CBT and fluoxetine (COMB). All inter-treatment differences (CBT vs. FLX; CBT vs. COMB; FLX vs. COMB) were evaluated across 23 potential effect modifiers extracted from previous studies. Overall, FLX was superior to CBT, while COMB was superior to both CBT and FLX. Evidence for effect heterogeneity was found for the CBT-FLX difference and the FLX-COMB difference, but not for the CBT-COMB difference. Baseline depression severity modified the CBT-FLX difference; whereas baseline depression severity, patients' treatment expectations, and childhood trauma modified the FLX-COMB difference. All modifications were quantitative rather than qualitative, however, meaning that the differences varied only in magnitude, but not direction. These findings imply that combining CBT with fluoxetine may be superior to either therapy used alone across a broad range of patients.

The Family Check Up and Adolescent Depression: An Examination of Treatment Responders and Non-Responders

The Family Check Up (FCU) is a family-centered intervention for reducing children's problem behavior through improving parenting skills and family interactions. Although the FCU was designed to prevent conduct problems, we have also found the program to be effective in preventing escalating symptoms of depression in early adolescence. The current analyses examine heterogeneous patterns of response to treatment in an effort to identify factors associated with differential response to family intervention. We examined heterogeneity in trajectories of youth-reported depressive symptoms from grades 6 to 9, using a Latent Growth Mixture Modeling framework to identify patterns of treatment response and non-response. Three symptom trajectories were identified, including the following: (1) a large class exhibiting stable, low symptom levels, (2) a class exhibiting high and stable depressive symptoms, and (3) a class exhibiting low initial symptoms that increased over time. Significant intervention effects were identified only among the third class, as a preventive effect on depression from 7th to 9th grade for youth with low initial symptoms. No effect of intervention was observed in the other two classes. Comparisons of classes 2 and 3 suggested that class 3 members were more likely to be females with high baseline antisocial behavior, but lower initial levels of depression. The findings suggest the importance of exploring heterogeneity within a prevention design, as well as the importance of tailored approaches to the prevention of adolescent depression.

Comorbid disorders as moderators of response to family interventions among adolescents with bipolar disorder

BACKGROUND

While family interventions have shown efficacy in improving mood symptoms and family functioning in pediatric bipolar disorder, few studies have examined the effects of comorbid psychiatric conditions on patients' symptomatic or functional responses to treatment.

METHODS

145 adolescents with bipolar I or II disorder were randomly assigned to family-focused therapy (FFT-A) or a brief psychoeducational therapy (enhanced care; EC) and followed over 2 years. Participants received pharmacotherapy for the study's duration. We examined whether comorbid anxiety disorders, attention-deficit/hyperactivity disorder (ADHD), and disruptive behavior disorders (DBDs; i.e., oppositional defiant and conduct disorder) predicted the proportion of weeks that participants experienced mood symptoms during follow-up, and whether comorbid disorders moderated the effects of treatment assignment on mood symptoms and family conflict.

RESULTS

Comorbid anxiety was associated with a greater proportion of weeks with depressive symptoms, more severe (hypo)manic symptoms during follow-up, and greater family conflict over the 2-year study. Comorbid ADHD was associated with a greater proportion of weeks with (hypo)manic symptoms, more severe (hypo)manic symptoms, and greater family conflict. Additionally, youth with comorbid ADHD who received FFT-A had more favorable trajectories of (hypo)manic symptoms and family functioning than youth with comorbid ADHD who received EC. Comorbid DBDs were consistently associated with more severe depressive symptoms and greater family conflict throughout the study.

LIMITATIONS

Randomization to treatments was not stratified on comorbid disorders. The longitudinal trajectories of anxiety, attentional, and disruptive behavior symptoms were not examined.

CONCLUSIONS

The course of bipolar disorder in adolescents is strongly affected by comorbid disorders. Future research should examine whether adolescents with more complex presentations of bipolar disorder should be treated with different or more intensive psychosocial protocols than adolescents without these presentations.

Parental Depressive Symptoms as a Predictor of Outcome in the Treatment of Child Internalizing and Externalizing Problems

Child internalizing and externalizing problems have been identified as high priority intervention targets by the World Health Organization. Parental depression is a risk factor for development of these childhood problems and may negatively influence intervention outcomes; however, studies have rarely assessed its influence on these outcomes. The present study assessed whether baseline parental depressive symptoms predicted psychotherapy outcomes among children treated for clinically significant internalizing and externalizing problems. The sample included 142 children (79 with primary internalizing problems, 63 with primary externalizing problems). Children were aged 7-13, 67.6% boys, and race included Caucasian (46.5%), African-American (9.9%), Latino (5.6%), Asian (1.4%), and multi-racial (32.4%). Analyses focused on child- and parent-reported weekly trajectories of change and post-treatment symptoms among children treated for internalizing and externalizing problems whose parents did (N = 28 and 25) and did not (N = 51 and 38) have elevated depressive symptoms. For children with internalizing problems, growth curve analyses showed markedly different trajectories, by child- and parent-report: children with less depressed parents showed significantly steeper symptom declines than did children with more depressed parents, who showed an increase in symptoms. ANCOVAs showed marginally lower post-treatment symptoms for children of less depressed versus more depressed parents (p = 0.064 by child-report). For children with externalizing problems, growth curve analyses showed trajectories in the opposite direction, by child- and parent-report; however, ANCOVAs showed no group differences at post-treatment. These findings suggest that it may be important to consider the impact of parental depressive symptoms when treating child internalizing and externalizing problems.

Effectiveness of CBT for children and adolescents with depression: A systematic review and meta-regression analysis

Background:

Cognitive-behavioral therapy (CBT) is first choice of treatment for depressive symptoms and disorders in adolescents, however improvements are necessary because overall efficacy is low. Insights on CBT components and contextual and structural characteristics might increase the efficacy. The aim of our approach is to evaluate the efficacy of CBT for youth with depression and investigate the influence of specific components, contextual and structural factors that could improve effects.

Methods:

A systematic review of randomized controlled trials was conducted, searches were undertaken in CINAHL, CENTRAL, EMBASE, MEDLINE/PubMed and PsycINFO. Outcomes were meta-analyzed and confidence in results was assessed using the GRADE-method. Meta-regression was used to pinpoint components or other factors that were associated with an in- or decrease of effects of CBT.

Results:

We included 31 trials with 4335 participants. Moderate-quality evidence was found for CBT reducing depressive symptoms at the end of treatment and at follow-up, and CBT as indicated prevention resulted in 63% less risk of being depressed at follow-up. CBT containing a combination of behavioral activation and challenging thoughts component (as part of cognitive restructuring) or the involvement of caregiver(s) in intervention were associated with better outcomes for youth on the long term.

Conclusions:

There is evidence that CBT is effective for youth with a (subclinical) depression. Our analyses show that effects might improve when CBT contains the components behavioral activation and challenging thoughts and also when the caregiver(s) are involved. However, the influential effects of these three moderators should be further tested in RCTs.

Emotion Regulation Among Adolescents With Pediatric Depression As a Function of Anxiety Comorbidity

Background: Both depression and anxiety (two of the most common internalizing psychopathologies among youths) are associated with difficulties in emotion regulation (ER). Little is known about whether anxiety as a comorbid condition has an effect on the habitual use of different ER strategies in youngsters with depression histories. We aimed 1) to compare ER in adolescents with histories of childhood onset major depressive disorder (MDD) with and without comorbid anxiety and 2) to examine whether certain ER response clusters (Cognitive, Social, and Behavioral/Physical) characterize comorbid children and adolescents. Methods: We analyzed data on 217 youth (11-18 years old) with depression history: 85 subjects with lifetime anxiety comorbidity (comorbid group) and 132 without lifetime anxiety (non-comorbid group). Psychiatric diagnosis was established by a comprehensive Diagnostic and Statistical Manual of Mental Disorders (DSM) IV-based diagnostic procedure. ER strategies were examined via the self-rated "Feelings and Me" Child version questionnaire (FAM-C). Results: The comorbid group used maladaptive ER strategies significantly more frequently than the non-comorbid youngsters. The Behavioral/Physical and Social ER skills, especially those reflecting social withdrawal and self-harm, were responsible for the higher maladaptive scores. Limitations: Because our study is a cross-sectional analysis, we have no information about the development or the onset of maladaptive ER strategies. Therefore, we were unable to examine whether maladaptive ER was a risk factor or a consequence of the internalizing psychopathology and comorbidity. Conclusions: Comorbid anxiety worsens the impaired use of ER strategies in depression-prone youths. Further longitudinal research is needed to explore the causal role of dysfunctional ER in the development of internalizing psychopathology.

Moderators and mediators of a maternal depression treatment study: Impact of maternal trauma and parenting on child outcomes

OBJECTIVE

Treatment of maternal depression with psychotherapy has been shown to confer indirect benefits to school-age offspring with psychiatric disorders. The current study sought to understand mechanisms by which improvement in depressed mothers, with and without histories of trauma and treated with psychotherapy, produce changes in children who struggle with psychiatric illnesses themselves. We hypothesized that maternal history of childhood trauma would moderate the relationship between maternal and child outcomes and that increased positive and decreased negative parenting behaviors would mediate the relationship between maternal and child outcomes. We also examined whether maternal history of trauma would moderate the mediational effects of parenting behaviors.

METHODS

Participants were dyads (n = 62) of mothers with major depressive disorder and their children, ages 7-18, with at least one internalizing disorder. Mothers were treated with nine sessions of psychotherapy and children were treated openly in the community. Dyads were evaluated every three months over one year.

RESULTS

Maternal improvement in depressive symptoms was associated, in a lagged fashion, with child improvement in functioning six months later. There was a significant interaction of time and change in maternal symptoms [F(1, 45) = 5.84, p = 0.02], where change in maternal depressive symptoms from baseline to six months was robustly associated with change in child functioning from baseline to 12 months (β = 0.49, p = 0.0002). Maternal history of childhood sexual abuse moderated the association between change in maternal and child depressive symptoms [F(1,87) = 5.8, p = 0.02], and maternal history of physical neglect moderated the relationship between improvement in maternal depression and improvement in child functioning [F(1,36) = 4.34, p = 0.04], where significant associations between maternal and child outcomes were only found in mothers without histories of sexual abuse or physical neglect. Increase in positive parenting strategies (acceptance) by mothers mediated 6-month lagged associations between maternal and child outcomes, but reduction in negative parenting strategies (psychological control) did not. Maternal history of childhood emotional neglect moderated the mediational model, such that improved positive parenting did not explain lagged improvement in child depression among the subset of mothers with childhood histories of emotional neglect.

CONCLUSIONS

In dyads comprised of depressed mothers and school-age children with internalizing disorders, children improved when mothers improved, but not among those whose mothers who had histories of sexual abuse or physical neglect. Increased use of positive parenting strategies among mothers accounted for lagged relationships between improvement in maternal depressive symptoms and improvement in child functioning. This pattern was not, however, observed among mothers with childhood histories of emotional neglect. Interventions that directly enhance positive parenting and more rapidly change these behaviors may hasten improvement in offspring. Offspring of depressed mothers with histories of early trauma are at high risk for poor outcomes, even when their mothers receive depression treatment.

Depression Change Profiles in Adolescents Treated for Comorbid Depression/Substance Abuse and Profile Membership Predictors

Using data from a randomized trial in which adolescents with depressive and substance use disorders (SUD) received treatments for both disorders in either a sequenced or coordinated manner, we (a) determine the number and nature of depression response profiles through 1-year posttreatment and (b) examine whether 8 previously identified factors predict profile membership. There were 170 adolescents (M age = 16.4 years; 22% female; 28% Hispanic, 61% Non-Hispanic White) with comorbid depressive disorder/SUD randomized to one of three sequences of receiving the Adolescent Coping With Depression Course and Functional Family Therapy for SUD (depression treatment followed by SUD treatment; SUD treatment followed by depression treatment; coordinated treatment). Depression was assessed at 7 points from baseline to 1-year follow-up. A 4-class solution fit the data best, with groups labeled Mildly Depressed Responders (57.1%), Depressed Responders (18.8%), Depressed Non-Responders (12.9%), and Depressed with Recurrence (11.2%). The 4 change profiles differed on indices of all but 1 predictor (age); most differences were driven by lower scores among Mildly Depressed Responders. Profile membership was most strongly predicted by depression severity, cognitive distortions, hopelessness, and global functioning. The strongest predictor of Nonresponse was low family cohesion, whereas Recurrence was associated with hopelessness, suicide attempts, and starting treatment near the end of the school year. Most depressed adolescents experienced a positive response that was maintained. Understanding the most common profiles of depression change during and following treatment and the variables that predict change can help improve treatment outcomes and advance tailoring efforts.

The influence of comorbid anxiety on the effectiveness of Cognitive Therapy and Interpersonal Psychotherapy for Major Depressive Disorder

BACKGROUND

Anxious depression is an important subtype of Major Depressive Disorder (MDD) defined by both syndromal (anxiety disorders) and dimensional (anxiety symptoms) criteria. A debated question is how anxiety affects MDD treatment. This study examined the impact of comorbid anxiety disorders and symptoms on the effectiveness of and dropout during Cognitive Therapy (CT) and Interpersonal Psychotherapy (IPT) for MDD.

METHODS

Depressed individuals were randomized to CT (n = 76) or IPT (n = 75). Outcome was depression severity measured with the Beck Depression Inventory-II (BDI-II) at the start of each therapy session, post treatment, and monthly up to five months follow-up. Anxiety disorders were assessed with the Structured Clinical Interview for DSM-IV Axis I disorders, (phobic) anxiety symptoms were assessed with Brief Symptom Inventory subscales.

RESULTS

Approximately one third of participants had a comorbid anxiety disorder. Comorbid anxiety disorders and anxiety symptoms were associated with less favorable depression change during IPT as compared to CT in the treatment phase, but not in the trial follow-up phase. Individuals with a comorbid anxiety disorder had significantly higher treatment dropout during both treatments.

LIMITATIONS

Not all therapists and participants were blind to the assessment of comorbid anxiety disorders and the assessments were performed by one rater.

CONCLUSIONS

A preference for CT over IPT for MDD is justifiable when comorbid anxiety is present, although long-term differences are not established and replication of this finding is needed. Clinicians should be aware of the risk of dropout for depressed individuals with an anxiety disorder.

Two-Year Impact of Prevention Programs on Adolescent Depression: an Integrative Data Analysis Approach

This paper presents the first findings of an integrative data analysis of individual-level data from 19 adolescent depression prevention trials (n = 5210) involving nine distinct interventions across 2 years post-randomization. In separate papers, several interventions have been found to decrease the risk of depressive disorders or elevated depressive/internalizing symptoms among youth. One type of intervention specifically targets youth without a depressive disorder who are at risk due to elevated depressive symptoms and/or having a parent with a depressive disorder. A second type of intervention targets two broad domains: prevention of problem behaviors, which we define as drug use/abuse, sexual risk behaviors, conduct disorder, or other externalizing problems, and general mental health. Most of these latter interventions improve parenting or family factors. We examined the shared and unique effects of these interventions by level of baseline youth depressive symptoms, sociodemographic characteristics of the youth (age, sex, parent education, and family income), type of intervention, and mode of intervention delivery to the youth, parent(s), or both. We harmonized eight different measures of depression utilized across these trials and used growth models to evaluate intervention impact over 2 years. We found a significant overall effect of these interventions on reducing depressive symptoms over 2 years and a stronger impact among those interventions that targeted depression specifically rather than problem behaviors or general mental health, especially when baseline symptoms were high. Implications for improving population-level impact are discussed.

Is behavioural activation effective in the treatment of depression in young people? A systematic review and meta-analysis

PURPOSE

Depression is currently the leading cause of illness and disability in young people. Evidence suggests that behavioural activation (BA) is an effective treatment for depression in adults but less research focuses on its application with young people. This review therefore examined whether BA is effective in the treatment of depression in young people.

METHODS

A systematic review (International Prospective Register of Systematic Reviews reference: CRD42015020453), following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, was conducted to examine studies that had explored behavioural interventions for young people with depression. The electronic databases searched included the Cochrane Library, EMBASE, MEDLINE, CINAHL Plus, PsychINFO, and Scopus. A meta-analysis employing a generic inverse variance, random-effects model was conducted on the included randomized controlled trials (RCTs) to examine whether there were overall effects of BA on the Children's Depression Rating Scale - Revised.

RESULTS

Ten studies met inclusion criteria: three RCTs and seven within-participant designs (total n = 170). The review showed that BA may be effective in the treatment of depression in young people. The Cochrane risk of bias tool and the Moncrieff scale used to assess the quality of the included studies revealed a variety of limitations within each.

CONCLUSIONS

Despite demonstrating that BA may be effective in the treatment of depression in young people, the review indicated a number of methodological problems in the included studies meaning that the results and conclusions should be treated with caution. Furthermore, the paucity of studies in this area highlights the need for further research.

PRACTITIONER POINTS

Currently BA is included within National Institute for Health and Clinical Excellence (NICE, 2009) guidelines as an evidence-based treatment for depression in adults with extensive research supporting its effectiveness. It is important to investigate whether it may also be effective in treating young people. Included studies reported reductions in depression scores across a range of measures following BA. BA may be an effective treatment of depression in young people.

Mental Health Care Use in Children of Parents with Mental Health Problems: Results of the BELLA Study

Whether parental mental health problems facilitate or hinder the use of mental health care of the parents´ children is still unclear. The present cross sectional study examined mental health care use and potential predictors in a population based sample. Children of parents with mental health problems (CPM) were nearly 5 times more likely to use mental health care compared to children of parents without mental health problems. A multiple regression analysis revealed that the most important predictors of mental health care use for CPM were active family life (OR = 2.67) and children´s own mental health problems (OR = 1.18 self-report, 1.17 parent-report). Additionally, parental strain showed a tendency to predict mental health care use (OR = 2.45). This study demonstrates that parental mental health problems are associated with mental health care use in their children and that improving certain family factors may support children´s mental health care use.

Agreement between clinical and MINI diagnoses in outpatients with mood and anxiety disorders

BACKGROUND

Standardized Diagnostic Interviews (SDIs) such as the Mini International Neuropsychiatric Interview (MINI) are widely used to systematically screen for psychiatric disorders in research. To support generalizability of results to clinical practice, we assessed agreement between the MINI and clinical diagnoses.

METHODS

Agreement was assessed in a large, real life dataset (n = 7016) using concordance statistics such as sensitivity, specificity, efficiency and area under the curve (AUC).

RESULTS

41.5% of clinical diagnoses were mood disorders, 26.5% were anxiety disorders. Overall, we found moderate agreement between MINI and clinical diagnoses (median efficiency: 0.92, median AUC: 0.79). For mood disorders, the AUC for all participants showed a range between 0.55 and 0.81 (median: 0.73), and for anxiety disorders the AUC ranged from 0.78 to 0.88 (median: 0.83). The AUC showed better agreement for mood disorders in the single diagnosis group than in the total group (median 0.77 vs. 0.71). For anxiety disorders, the AUC for the single diagnosis group was comparable to the AUC of the total group (median: 0.81 vs. 0.83 respectively). Numbers of false positives were high for both mood and anxiety diagnoses, but less so in the single diagnosis group.

LIMITATIONS

Time lag between MINI and clinical diagnosis, the availability of only the primary clinical diagnosis, and relatively high severity of the current sample are limitations of the current study.

CONCLUSIONS

Agreement between MINI and clinical diagnoses was moderate at best, which partly reflects the difference between the different measures used in the current study.

Parental Factors Associated with Rumination Related Metacognitive Beliefs in Adolescence

An increasing number of research studies have suggested that metacognition is associated with individuals' mental health. Specifically, metacognitive beliefs about rumination was proposed to link to the onset and maintenance of depression according to the metacognitive model of depression. The current study aimed to serve as a pilot study exploring how parents' metacognitive beliefs and parenting characteristics are associated with rumination related metacognitive beliefs in adolescents. Eighty-five parent-youth dyads were invited to complete a set of questionnaires examining their metacognitive beliefs about rumination followed by a difficult puzzle task, in which parent-adolescent interaction patterns were recorded to examine the parenting style. Results found that parents' and adolescents' positive metacognitive beliefs about rumination were significantly associated with each other. In addition, parental negativity was significantly associated with adolescents' positive metacognitive beliefs of rumination and parental over-involvement was marginally associated with adolescents' negative metacognitive beliefs of rumination. The findings highlighted the association between parental factors and adolescents' metacognitive beliefs about rumination. Implications on the prevention of adolescent's depression were discussed.
