- A smartphone-assisted brief online cognitive-behavioral intervention for pregnant women with depression: a study protocol of a randomized controlled trial(2021) ZUCCOLO, Pedro Fonseca; XAVIER, Mariana O.; MATIJASEVICH, Alicia; POLANCZYK, Guilherme; FATORI, DanielBackgroundPregnancy is strongly associated with increased risk for depression. Approximately 25% of pregnant women develop depression. Treatment for depression during pregnancy has several complexities: the use of psychiatric medications during pregnancy might result in developmental problems in the child and must be used with caution. Psychosocial interventions are effective, but they require specialized professionals. Low- and middle-income countries (LMIC) such as Brazil do not have enough mental health professionals needed to meet this demand. In this context, smartphone-based interventions show immense potential. We developed Motherly, a smartphone application (app) designed to treat maternal depression. We aim to test the efficacy of Motherly in addition to brief cognitive-behavioral therapies (CBT) to treat maternal depression.MethodsWe will conduct a 2-arm parallel-randomized controlled clinical trial in which 70 pregnant women aged between 16 and 40years with depression will be randomized to intervention or active control. The intervention group will have access to Motherly, a smartphone app based on three concepts: psychoeducation, behavior monitoring, and gaming elements. Motherly is composed of a package of interventions composed of modules: mental health, sleep, nutrition, physical activity, social support, prenatal/postnatal support, and educational content. The main focus of Motherly is delivering behavioral activation (BA), a brief and structured psychological treatment. The app allows participants to schedule and engage in, and monitor activities according to a plan to avoid acting exclusively according to their mood. The active control group will have access to a simplified version of the app consisting of educational content about various aspects of pregnancy, maternal physical and mental health, and infant development (BA, activity scheduling, sleep hygiene, among other functionalities, will not be present in this version). Both groups will receive four sessions of brief CBT in 8weeks. Participants will be evaluated by assessors blind to randomization and allocation status. Assessments will occur at baseline (T0), midpoint (T1, week 4-5), posttreatment (T2, week 8), and follow-up (T3, when the child is 2 months old). Maternal mental health (prenatal anxiety, psychological well-being, perceived stress, depression, depression severity, and sleep quality), quality of life, physical activity levels, and infant developmental milestones and social/emotional problems will be measured. Our primary outcome is the change in maternal prenatal depression from baseline to posttreatment (8weeks).DiscussionThe potential of digital technology to deliver mental health interventions has been increasingly recognized worldwide. There is a growing literature on interventions using smartphone applications to promote mental health, both with or without the intermediation of a mental health professional. Our study adds to the literature by testing whether an app providing an intervention package, including CBT, psychoeducation, nutrition, physical activity, and social support, can promote maternal and child health and well-being. In particular, we aim to treat depression, for which the use of digital technologies is still scarce. Smartphone applications designed to treat maternal depression are especially relevant because of the potential to circumvent barriers that prevent pregnant women from accessing mental health care.Trial registrationClinicalTrials.gov NCT04495166.

- Smartphone-assisted online brief cognitive behavioral therapy to treat maternal depression: findings of a randomized controlled trial(2023) FATORI, Daniel; ZUCCOLO, Pedro; XAVIER, Mariana O.; MATIJASEVICH, Alicia; POLANCZYK, Guilherme V.Objective: To test the efficacy of smartphone-assisted online brief cognitive behavioral therapy (b-CBT) to treat maternal depression compared to online brief CBT plus an active control app.Methods: A randomized controlled trial was conducted. Assessments were performed at baseline (T0), midpoint (T1, week 4-5), post-treatment (T2, week 8), and follow-up (T3, 2-month postnatal follow-up) by blinded interviewers. The primary outcome was depression measured by the Edinburgh Postnatal Depression Scale (EPDS) at T2. We also assessed anxiety, stress, sleep quality, well-being, physical activity, treatment response, and offspring child behavior problems. Results: Eighty-one participants were randomized to the intervention (n=37) or active control (n=44) groups. Seventy-one participants completed the post-treatment assessment or reported primary outcome data. No differences were found between the intervention and active control groups regarding maternal depression or other mental health outcomes. Overall, we found large within-group effect sizes, with 80% of the total sample responding to treatment. Conclusions: Our data showed no difference between the groups, suggesting that adding apps to psychotherapy treatment may not enhance treatment effects on prenatal depression. A within-groups analysis showed that most participants with depression responded to treatment; however, future studies are needed to confirm whether this effect is related to factors other than the intervention.

- A randomized controlled trial testing the efficacy of a Nurse Home Visiting Program for Pregnant Adolescents(2021) FATORI, Daniel; ZUCCOLO, Pedro Fonseca; SHEPHARD, Elizabeth; BRENTANI, Helena; MATIJASEVICH, Alicia; FERRARO, Alexandre Archanjo; FRACOLLI, Lislaine Aparecida; CHIESA, Anna Maria; LECKMAN, James; MIGUEL, Euripedes Constantino; POLANCZYK, Guilherme V.To test the efficacy of a nurse home visiting program (HVP) on child development, maternal and environmental outcomes in the first years of life. We conducted a randomized controlled trial to test the efficacy of Primeiros Lacos, a nurse HVP for adolescent mothers living in a poor urban area of SAo Paulo, Brazil. Eighty adolescent mothers were included and randomized to receive either Primeiros Lacos (intervention group, n=40) or healthcare as usual (control group, n=40). Primeiros Lacos is a home visiting intervention delivered by trained nurses that starts during the first 16 weeks of pregnancy and continues to the child's age of 24 months. Participants were assessed by blind interviewers at 8-16 weeks of pregnancy (baseline), 30 weeks of pregnancy, and 3, 6, 12, and 24 months of child's age. We assessed oscillatory power in the mid-range alpha frequency via electroencephalography when the children were aged 6 months. Child development was measured by the Bayley Scales of Infant Development Third Edition (BSID-III). Weight and length were measured by trained professionals and anthropometric indexes were calculated. The home environment and maternal interaction with the child was measured by the Home Observation and Measurement of the Environment. Generalized estimating equation models were used to examine intervention effects on the trajectories of outcomes. Standardized effect sizes (Cohen's d) were calculated using marginal means from endpoint assessments of all outcomes. The trial was registered at clinicaltrial.gov: NCT02807818. Our analyses showed significant positive effects of the intervention on child expressive language development (coefficient=0.89, 95% CI [0.18, 1.61], p=0.014), maternal emotional/verbal responsivity (coefficient=0.97, 95% CI [0.37, 1.58], p=0.002), and opportunities for variety in daily stimulation (coefficient=0.37, 95% CI [0.09, 0.66], p=0.009). Standardized effect sizes of the intervention were small to moderate. Primeiros Lacos is a promising intervention to promote child development and to improve the home environment of low-income adolescent mothers. However, considering the limitations of our study, future studies should be conducted to assess Primeiros Lacos potential to benefit this population.Clinical Trial Registration: The study was registered at clinicaltrial.gov (Registration date: 21/06/2016 and Registration number: NCT02807818).
- Instrumental activities of daily living performance in healthy and cognitively intact seniors from a Brazilian sample and its relation to age and other socio-demographic variables(2012) ZUCCOLO, Pedro Fonseca; AVILA, Renata; NAKANO, Eduardo Y.; LITVOC, Julio; LOPES, Marcos A.; BOTTINO, Cassio M. C.Background: Studies on functional capacity in community-dwelling older people have shown associations between declines in instrumental activities of daily living (IADL) and several factors. Among these, age has been the most consistently related to functional capacity independent of other variables. We aimed at evaluating the performance of a sample of healthy and cognitively intact Brazilian older people on activities of daily living and to analyze its relation to social-demographic variables. Methods: We conducted a secondary analysis of data collected for previous epidemiological studies with community-dwelling subjects aged 60 years or more. We selected subjects who did not have dementia or depression, and with no history of neurological diseases, heart attack, HIV, hepatitis or arthritis (n = 1,111). Functional capacity was assessed using the Brazilian version of the Older American Resources and Services Questionnaire (BOMFAQ). ADL performance was analyzed according to age, gender, education, and marital status (Pearson's chi(2), logistic regression). Results: IADL difficulties were present in our sample, especially in subjects aged 80 years or more, with lower levels of education, or widowed. The logistic regression analysis results indicated that ""higher age"" and ""lower education"" (p <= 0.001) remained significantly associated with IADL difficulty. Conclusions: Functional decline was present in older subjects even in the absence of medical conditions and cognitive impairment. Clinicians and researchers could benefit from knowing what to expect from older people regarding IADL performance in the absence of medical conditions.
- A systematic review and meta-analysis of altered electrophysiological markers of performance monitoring in Obsessive-Compulsive Disorder (OCD), Gilles de la Tourette Syndrome (GTS), Attention-Deficit/Hyperactivity disorder (ADHD) and Autism(2021) BELLATO, Alessio; NORMAN, Luke; IDREES, Iman; OGAWA, Carolina Y.; WAITT, Alice; ZUCCOLO, Pedro F.; TYE, Charlotte; RADUA, Joaquim; GROOM, Madeleine J.; SHEPHARD, ElizabethAltered performance monitoring is implicated in obsessive-compulsive disorder (OCD), Gilles de la Tourette syndrome (GTS), attention-deficit/hyperactivity disorder (ADHD) and autism. We conducted a systematic review and meta-analysis of electrophysiological correlates of performance monitoring (error-related negativity, ERN; error positivity, Pe; feedback-related negativity, FRN; feedback-P3) in individuals with OCD, GTS, ADHD or autism compared to control participants, or associations between correlates and symptoms/traits of these con-ditions. Meta-analyses on 97 studies (5890 participants) showed increased ERN in OCD (Hedge's g = 0.54 [CIs:0.44,0.65]) and GTS (g = 0.99[CIs:0.05,1.93]). OCD also showed increased Pe (g = 0.51[CIs:0.21,0.81]) and FRN (g = 0.50[CIs:0.26,0.73]). ADHD and autism showed reduced ERN (ADHD: g=-0.47[CIs:-0.67,-0.26]; autism: g=-0.61[CIs:-1.10,-0.13]). ADHD also showed reduced Pe (g=-0.50[CIs:-0.69,-0.32]). These findings suggest overlap in electrophysiological markers of performance monitoring alterations in four common neuro-developmental conditions, with increased amplitudes of the markers in OCD and GTS and decreased amplitudes in ADHD and autism. Implications of these findings in terms of shared and distinct performance monitoring alterations across these neurodevelopmental conditions are discussed.
- Children and adolescents' emotional problems during the COVID-19 pandemic in Brazil(2023) ZUCCOLO, Pedro Fonseca; CASELLA, Caio Borba; FATORI, Daniel; SHEPHARD, Elizabeth; SUGAYA, Luisa; GURGEL, Wagner; FARHAT, Luis Carlos; ARGEU, Adriana; TEIXEIRA, Monike; OTOCH, Luara; V, Guilherme PolanczykBrazil has been severely affected by the COVID-19 pandemic with one of the largest numbers of youth impacted by school closure globally. This longitudinal online survey assessed emotional problems in children and adolescents aged 5-17 years living in Brazil during the COVID-19 pandemic. Recruitment occurred between June to November 2020 and participants were invited for follow-up assessments every 15 days until June 2021. Participants were 5795 children and adolescents living across the country with mean age of 10.7 (SD 3.63) years at recruitment; 50.5% were boys and 69% of white ethnicity. Weighted prevalence rates of anxiety, depressive and total emotional symptoms at baseline were 29.7%, 36.1% and 36%, respectively. Longitudinal analysis included 3221 (55.6%) participants and revealed fluctuations in anxiety and depressive symptoms during one year follow-up, associated with periods of social mobility and mortality. Emotional problems significantly increased in July and September 2020 and decreased from December 2020 to February 2021 and then significantly increased in May 2021 relative to June 2020. Older age, feeling lonely, previous diagnosis of mental or neurodevelopmental disorder, previous exposure to traumatic events or psychological aggression, parental psychopathology, and sleeping less than 8/h a day were associated with increased rates of anxiety and depressive symptoms at baseline and over time. Food insecurity and less social contact with family and peers were associated with baseline anxiety and depressive symptoms, and lowest socio-economic strata, chronic disease requiring treatment and family members physically ill due to COVID-19 were associated with increasing rates over time. The pandemic severely affected youth, particularly those from vulnerable populations and in moments of increased mortality and decreased social mobility. Results underscore the need for allocation of resources to services and the continuous monitoring of mental health problems among children and adolescents.
bookPart O exame neuropsicológico e os diferentes contextos de aplicação(2014) CAMARGO, Candida Helena Pires de; BOLOGNANI, Silvia Adriana Prado; ZUCCOLO, Pedro Fonseca- Systematic Review and Meta-analysis: The Science of Early-Life Precursors and Interventions for Attention-Deficit/Hyperactivity Disorder(2022) SHEPHARD, Elizabeth; ZUCCOLO, Pedro F.; IDREES, Iman; GODOY, Priscilla B. G.; SALOMONE, Erica; FERRANTE, Camilla; SORGATO, Paola; CATAO, Luis F. C. C.; GOODWIN, Amy; BOLTON, Patrick F.; TYE, Charlotte; GROOM, Madeleine J.; POLANCZYK, Guilherme V.Objective: To evaluate which early neurocognitive and behavioral precursors are associated with the development of attention-deficit/hyperactivity disorder (ADHD) and whether these are currently targeted in early interventions. Method: We conducted 2 systematic reviews and meta-analyses of empirical studies to examine the following: (1) early-life (0-5 years) neurocognitive and behavioral precursors associated with familial likelihood for ADHD, an early ADHD diagnosis/elevated ADHD symptoms, and/or the presence of later-childhood ADHD; and (2) interventions delivered to children aged 0 to 5 years targeting the identified precursors or measuring these as outcomes. Standardized mean differences (Hedges' g) and pre-post-treatment change scores (SMD) were computed. Results: A total of 149 studies (165,095 participants) investigating 8 neurocognitive and behavioral domains met inclusion criteria for part 1. Multilevel random-effects meta-analyses on 136 studies revealed significant associations between ADHD and poorer cognitive (g = -0.46 [95% CIs: -0.59, -0.33]), motor (g = -0.35 [CIs: -0.48, -0.21]) and language (g = -0.43 [CIs: -0.66, -0.19]) development, social (g = 0.23 [CIs: 0.03, 0.43]) and emotional (g = 0.46 [CIs: 0.33, 0.58]) difficulties, early regulatory (g = 0.30 [CIs: 0.18, 0.43]) and sleep (g = 0.29 [CIs: 0.14, 0.44]) problems, sensory atypicalities (g = 0.52 [CIs: 0.16, 0.88]), elevated activity levels (g = 0.54 [CIs: 0.37, 0.72]), and executive function difficulties (g = 0.34 [CIs: 0.05, 0.64] to -0.87 [CIs: -1.35, -0.40]). A total of 32 trials (28 randomized, 4 nonrandomized, 3,848 participants) testing early interventions that targeted the identified precursors met inclusion criteria for part 2. Multi-level random-effects meta-analyses on 22 studies revealed significant intervention-related improvements in ADHD symptoms (SMD = 0.43 [CIs: 0.22, 0.64]) and working memory (SMD = 0.37 [CIs: 0.06, 0.69]). Conclusion: Children aged 0 to 5 years with current or later-emerging ADHD are likely to experience difficulties in multiple neurocognitive/behavioral functions. Early interventions show some effectiveness in reducing ADHD symptoms, but their effects on neurocognitive/behavioral difficulties require further study.
- Neurocircuit models of obsessive-compulsive disorder: limitations and future directions for research(2022) SHEPHARD, Elizabeth; BATISTUZZO, Marcelo C.; HOEXTER, Marcelo Q.; STERN, Emily R.; ZUCCOLO, Pedro F.; OGAWA, Carolina Y.; SILVA, Renata M.; BRUNONI, Andre R.; COSTA, Daniel L.; DORETTO, Victoria; SARAIVA, Leonardo; CAPPI, Carolina; SHAVITT, Roseli G.; SIMPSON, H. Blair; HEUVEL, Odile A. van den; MIGUEL, Euripedes C.Obsessive-compulsive disorder (OCD) is a common psychiatric condition classically characterized by obsessions (recurrent, intrusive and unwanted thoughts) and compulsions (excessive, repetitive and ritualistic behaviors or mental acts). OCD is heterogeneous in its clinical presentation and not all patients respond to first-line treatments. Several neurocircuit models of OCD have been proposed with the aim of providing a better understanding of the neural and cognitive mechanisms involved in the disorder. These models use advances in neuroscience and findings from neuropsychological and neuroimaging studies to suggest links between clinical profiles that reflect the symptoms and experiences of patients and dysfunctions in specific neurocircuits. Several models propose that treatments for OCD could be improved if directed to specific neurocircuit dysfunctions, thereby restoring efficient neurocognitive function and ameliorating the symptomatology of each associated clinical profile. Yet, there are several important limitations to neurocircuit models of OCD. The purpose of the current review is to highlight some of these limitations, including issues related to the complexity of brain and cognitive function, the clinical presentation and course of OCD, etiological factors, and treatment methods proposed by the models. We also provide suggestions for future research to advance neurocircuit models of OCD and facilitate translation to clinical application.
