The positive impact of an intervention for maternal depression on child emotional and behavioral symptoms in a low-resource setting

Objectives: Children of depressed mothers are at risk of developing mental health problems. We sought to determine whether treatment for maternal depression by community-based health workers would decrease behavioral/emotional symptoms in their children. Interventions for maternal depressive symptoms in a low/middle-income country can have a high global impact. Methods: Community-based health workers were trained to deliver a psychosocial intervention for mothers with depression in a primary care setting. A total of 49 mothers and 60 children were assessed pre-intervention, post-intervention, and at 6 months follow-up. Child behavioral/emotional symptoms were evaluated according to type of change in maternal depressive symptoms: response or remission. Results: An overall decrease in maternal depressive symptoms from baseline to post-intervention and 6 months follow-up were found. Response or remission was associated with better outcomes in child behavioral/emotional symptoms at 6 months follow-up (p = 0.0247, Cohen's d: 0.76; p = 0.0224, Cohen's f: 0.44) but not at post-intervention (p = 0.1636, Cohen's d: 0.48; p = 0.0720, Cohen's f: 0.33). Conclusions: Improvement in maternal depression was related to decreased behavioral/emotional symptoms in their children. Our results suggest that providing interventions for maternal depression in primary care is a viable strategy to prevent behavioral/emotional symptoms in the next generation.

Possible solutions to the shortcomings of the Yale-Brown Obsessive-Compulsive Scale / Possíveis soluções para as deficiências da escala de Yale-Brown para avaliação do transtorno obsessivo-compulsivo

OBJECTIVE: The Yale-Brown Obsessive-Compulsive Scale is the most frequently used instrument to measure obsessive-compulsive symptom severity. We describe its shortcomings and propose new methods of evaluating current severity and treatment response. METHOD: The Yale-Brown Obsessive-Compulsive Scale total and subscale scores were pooled from one cross-sectional study database containing information on 1,000 obsessive-compulsive disorder patients from seven specialized mental health care centers. Additional longitudinal data were pooled for 155 patients who participated in a 12-week trial that evaluated the effectiveness of fluoxetine vs. cognitive-behavior therapy as first-line treatment options. All patients were followed by a clinician who provided a clinical opinion of improvement. Neither patients nor clinicians were aware of the classifications proposed in this study. New methods for using the severity scores were compared with the clinical opinion of improvement. RESULTS: In the Yale-Brown Obsessive-compulsive scale, the summing-up of subscale scores to compose a total score does not accurately reflect clinical severity. In addition, the reduction of scores with treatment does not usually reach score zero in either subscale. To overcome such problems, we suggest (a) use of the maximum score of any of the subscales; (b) use of a minimum score of 4 in each subscale or 5 for the maximum in any subscale as the goal after treatment. This method performed better than traditional ones regarding sensitivity and specificity against the gold standard represented by the clinical opinion of improvement. CONCLUSION: The new proposed response criteria are coherent with the clinical opinion of improvement and perform better than the traditional methodology.

RESUMO OBJETIVO: A escala de Yale-Brown para avaliação do transtorno obsessivo-compulsivo é o instrumento mais utilizado para medir a gravidade desse transtorno. Descrevemos as deficiências dessa escala e propomos novos métodos de cálculo dos escores para avaliação de gravidade e resposta ao tratamento. MÉTODO: Os escores totais e subtotais da escala de Yale-Brown foram recuperados de um banco de dados de um estudo transversal com informações sobre 1.000 pacientes com transtorno obsessivo-compulsivos atendidos em sete centros especializados em saúde mental. Foram acrescentados os dados longitudinais de 155 pacientes participantes de um ensaio clínico de 12 semanas que avaliou a eficácia da fluoxetina ou da terapia cognitivo-comportamental como opções de tratamento de primeira linha. Todos os pacientes foram acompanhados por um médico que forneceu um parecer clínico de melhora. Nem os pacientes nem os médicos estavam conscientes das classificações propostas neste estudo. Novos métodos para avaliar os escores de gravidade foram comparados com o parecer clínico de melhora. RESULTADOS: Na escala obsessivo-compulsiva Yale-Brown, a soma de sub-escalas para compor a pontuação total não reflete com precisão a gravidade clínica. Além disso, a redução da pontuação com o tratamento, normalmente, não atinge o valor zero em qualquer das sub-escalas. Para superar esses problemas, sugerimos (a) o uso da pontuação máxima de qualquer das sub-escalas antes do tratamento; (b) o uso de um score mínimo de 4 em cada sub-escala ou um escore mínimo de 5 como o máximo de qualquer das sub-escalas como a meta para o pós-tratamento. Os novos métodos propostos tiveram melhor desempenho do que os tradicionais quanto a sensibilidade e especificidade contra o padrão ouro representado pelo parecer clínico de melhora. CONCLUSÃO: Os novos critérios propostos são coerentes com o parecer clínico de melhora e desempenham melhor do que a metodologia tradicional.

Quality of life of mothers whose children work on the streets of São Paulo, Brazil / Qualidade de vida de mães de crianças trabalhadoras de rua da cidade de São Paulo, Brasil / La calidad de vida de las madres de niños trabajadores en las calles de São Paulo, Brasil

The present study evaluated the perceived quality of life of the mothers of street children and investigated the association with their history of childhood violence, the occurrence of current domestic violence, their current mental states and that of their children, and family functioning. The applied instruments were as follows: Strengths and Difficulties Questionnaire, WorldSAFECore Questionnaire, Instrument for the Assessment of Quality of Life of the WHO, Global Assessment of Relational Functioning Scale, Childhood Trauma Questionnaire and a socio-demographic questionnaire. The sample of convenience consisted of 79 low-income mothers who raised their children alone, and most of whom had a positive screening for mental illness. The multiple regression analysis showed that the perception of quality of life of these women was associated with the presence of psychopathology either in themselves or their children and family dysfunction. Thus any program aimed at improving the quality of life of such mothers should consider addressing their mental problems as well as those of their children, besides offering educational and psychotherapeutic approaches to these families to improve the social environment.

Avaliamos a percepção da qualidade de vida de mães de crianças em situação de rua e investigamos a sua possível associação com os antecedentes maternos de abuso e violência na infância e vitimização atual, sintomas emocionais delas e de seus filhos e com o funcionamento familiar. Foram aplicados os seguintes instrumentos: Instrumento para a Avaliação da Qualidade de Vida da OMS - versão abreviada, Questionário de Capacidades e Dificuldades, WorldSAFECore Questionnaire, Escala de Avaliação Global de Funcionamento nas Relações Familiares, Childhood Trauma Questionnaire e um questionário sociodemográfico. Nossa amostra de conveniência foi constituída por 79 mães, a maioria delas com rastreamento positivo para doença mental. Aplicamos um modelo de regressão múltipla que encontrou associação entre a percepção de pior qualidade de vida com a presença de psicopatologia nelas e em seus filhos e com pior funcionamento familiar. Dessa forma, qualquer programa voltado para a melhora da qualidade de vida de mães nessa condição deve considerar a abordagem de problemas mentais nelas e em seus filhos, além de oferecer recursos educacionais e psicoterapêuticos para as famílias, visando à melhora das condições socioambientais.

Se presenta aquí una evaluación de la calidad de vida percibida por madres de niños en las calles, y se investigó la posible asociación con antecedentes maternos de abuso y violencia en la infancia y victimización actual, los síntomas emocionales de ellos y de sus hijos y el funcionamiento familiar. Se aplicaron los Instrumentos para la Evaluación de la Calidad de Vida de la OMS - versión abreviada, Cuestionario de Capacidades y Dificultades, WorldSAFECore Questionnaire, Escala de Evaluación Global de Funcionamiento en las Relaciones Familiares, Childhood Trauma Questionnaire y un cuestionario sociodemográfico. La muestra incluyó a 79 madres, la mayoría de ellas con una detección positiva para la enfermedad mental. La percepción de calidad de vida se asoció con la presencia de psicopatología en ellos y sus hijos y el funcionamiento familiar. Por lo tanto, cualquier programa destinado a mejorar la calidad de vida de las madres en esta condición debe considerar el enfoque de los problemas mentales en ellos y sus hijos y ofrecer trabajo educativo y terapéutico a esas familias.

Lack of association between the 5-HTTLPR and positive screening for mental disorders among children exposed to urban violence and maltreatment

Objective: To ascertain whether genetic variations in the serotonin transporter gene (5-HTTLPR 44-bp insertion/deletion polymorphism) influence an increase in depressive and anxiety symptoms in children and adolescents exposed to high levels of violence. Methods: Saliva samples were collected from a group of children who were working on the streets and from their siblings who did not work on the streets. DNA was extracted from the saliva samples and analyzed for 5-HTTLPR polymorphism genotypes. Results: One hundred and seventy-seven children between the ages of 7 and 14 years were analyzed (114 child workers and 63 siblings). Data on socioeconomic conditions, mental symptoms, and presence and severity of maltreatment and urban violence were collected using a sociodemographic inventory and clinical instruments. There was no positive correlation between the 5-HTTLPR polymorphism and presence of mental symptoms in our sample, although the children were exposed to high levels of abuse, neglect, and urban violence. Conclusions: Despite previous studies that associated adult psychiatric disorders with the 5-HTTLPR polymorphism and a history of childhood maltreatment, no such association was found in this sample of children at risk. .

Exposure to maltreatment and urban violence in children working on the streets in São Paulo, Brazil: factors associated with street work

Objective: To quantitatively study the exposure to childhood maltreatment and urban violence in children from families with at least one child working on the streets and to investigate the relationship between these factors and street work. Methods: Families who participated in a nongovernmental organization (NGO) program to eliminate child labor were included. Data concerning sociodemographic characteristics, punishment methods used in the family environment against the children, five types of abuse and neglect perpetrated by the caregivers, urban violence exposure and family functioning were collected. Results: The sample included 126 children who were working on the streets and 65 siblings who were not working on the streets. Caregivers reported high levels of severe physical punishment. The children reported high levels of abuse and neglect, and high levels of urban violence exposure. The families showed a predominance of dysfunctional and unsatisfactory relationships. A multiple logistic regression model showed that age older than 12 years and severe physical punishment at home were associated with street work. Conclusion: Interventions to decrease the risk of child street work should be family-focused and should aim to reduce violence in the family environment. .

Healthy maternal bonding as a resilience factor for depressive disorder

INTRODUCTION: Depressive disorders (DDs) are very prevalent disorders particularly in women, a high-risk gender group. Determining the risk and protective factors associated with the development of DDs is fundamental to planning preventive and therapeutic strategies. In this study, we evaluated the correlations between healthy maternal attachment and the development of DDs in adulthood. METHODS: We evaluated 52 women at 6 months to 1 year after premature childbirth at Maternidade Vila Nova Cachoeirinha. They were evaluated using the following instruments: Brazilian Criteria of Economic Classification, Parental Bonding Inventory (PBI), Center for Epidemiologic Studies Depression Scale (CES-D), and Edinburgh Postnatal Depression Scale (EPDS). Cut-off scores on the CES-D and EPDS were used to classifythe subjects as currently having a DD or having probable postpartum disorder (PPD) after childbirth. Multiple logistic regression was used to evaluate the risk factors associated with DDs. RESULTS: We found that 49.1% of the sample had a current depressive episode, and 73.6% had probable PPD. Based on logistic regression, current depression (odds ratio = 1.092 [confidence interval: 1.005; 1.186]), and a PPD (odds ratio = 1.108 [confidence interval: 1.011; 1.21]) were negatively correlated with affective maternal relationships. CONCLUSIONS: Women who reported healthy attachment with their mothers did not develop DDs when faced with stressful situations such as premature childbirth.

Risk factors for early treatment discontinuation in patients with obsessive-compulsive disorder

INTRODUCTION: In obsessive-compulsive disorder, early treatment discontinuation can hamper the effectiveness of first-line treatments. OBJECTIVE: This study aimed to investigate the clinical correlates of early treatment discontinuation among obsessive-compulsive disorder patients. METHODS: A group of patients who stopped taking selective serotonin reuptake inhibitors (SSRIs) or stopped participating in cognitive behavioral therapy before completion of the first twelve weeks (total n = 41; n = 16 for cognitive behavioral therapy and n = 25 for SSRIs) were compared with a paired sample of compliant patients (n = 41). Demographic and clinical characteristics were obtained at baseline using structured clinical interviews. Chisquare and Mann-Whitney tests were used when indicated. Variables presenting a p value <0.15 for the difference between groups were selected for inclusion in a logistic regression analysis that used an interaction model with treatment dropout as the response variable. RESULTS: Agoraphobia was only present in one (2.4 percent) patient who completed the twelve-week therapy, whereas it was present in six (15.0 percent) patients who dropped out (p = 0.044). Social phobia was present in eight (19.5 percent) patients who completed the twelve-week therapy and eighteen (45 percent) patients who dropped out (p = 0.014). Generalized anxiety disorder was present in eight (19.5 percent) patients who completed the twelve-week therapy and twenty (50 percent) dropouts (p = 0.004), and somatization disorder was not present in any of the patients who completed the twelveweek therapy; however, it was present in six (15 percent) dropouts (p = 0.010). According to the logistic regression model, treatment modality (p = 0.05), agoraphobia, the Brown Assessment of Beliefs Scale scores (p = 0.03) and the Beck Anxiety Inventory (p = 0.02) scores were significantly associated with the probability of treatment discontinuation irrespective of interactions with other variables. DISCUSSION AND CONCLUSION: Early treatment discontinuation is a common phenomenon in obsessive-compulsive disorder patients from our therapeutic setting. Psychiatric comorbidities were associated with discontinuation rates of specific treatments. Future studies might use this information to improve management for increased compliance and treatment effectiveness.

Sequential allocation to balance prognostic factors in a psychiatric clinical trial

OBJECTIVE: This paper aims to describe and discuss a minimization procedure specifically designed for a clinical trial that evaluates treatment efficacy for OCD patients. METHOD: Aitchison's compositional distance was used to calculate vectors for each possibility of allocation in a covariate adaptive method. Two different procedures were designed to allocate patients in small blocks or sequentially one-by-one. RESULTS: We present partial results of this allocation procedure as well as simulated data. In the clinical trial for which this procedure was developed, successful balancing between treatment arms was achieved. Separately, in an exploratory analysis, we found that if the arrival order of patients was altered, most patients were allocated to a different treatment arm than their original assignment. CONCLUSION: Our results show that the random arrival order of patients determine different assignments and therefore maintains the unpredictability of the allocation method. We conclude that our proposed procedure allows for the use of a large number of prognostic factors in a given allocation decision. Our method seems adequate for the design of the psychiatric trials used as models. Trial registrations are available at clinicaltrials.gov NCT00466609 and NCT00680602.
