Maternal Adversity Vulnerability and Neurodevelopment (MAVAN) project is a prospective community-based, pregnancy and birth cohort of Canadian mother-child dyads. The main objective of MAVAN project is to examine the pre- and postnatal influences, and their interaction, in determining individual differences in children development. The MAVAN project is designed to examine the consequences of fetal adversity as a function of the quality of the postnatal environment, focusing on mother-infant interactions.
In 2003 the Canadian Institutes of Health Research (CIHR) funded an ambitious and internationally unique study on the development of individual differences in vulnerability for mental illness. Increasing evidence indicates that many forms of mental illness as well as diabetes and cardiovascular disease are best considered as developmental disorders where vulnerability emerges as a function of genetic and epigenetic events. Frank pathology then develops as a function of the continuous interaction between underlying vulnerability and prevailing environmental triggers. The critical question is that of understanding the mechanisms by which specific forms of gene x environment interactions in perinatal life define the level of vulnerability/resistance to illness.
Maternal adversity during fetal life including maternal stress (as well as depression), low social support, poor maternal nutrition, and tobacco/alcohol consumption predict both preterm labour and intrauterine growth restriction. These birth outcomes, in turn, represent major epidemiological risk factors for heart disease, diabetes, and depression in adulthood, and neurodevelopmental impairments in children. Postnatal maternal adversity compromises maternal care/behaviour and infant development, and predicts increased risk for obesity, heart disease, attentional deficit disorders (ADD), drug abuse, and depression. Despite the enormous potential for the interaction of prenatal and postnatal influences, research has largely been restricted to the effects of events occurring during only one developmental period which, among other things, ignores the potential importance of 'protective' factors operating at later stages in life. Moreover, the underlying mechanisms by which perinatal adversity might directly affect neurocognitive development have been very poorly studied.
The investigators proposed an innovative research program that focuses on child development using a longitudinal, within-subject design examining neural and cognitive/emotional outcomes as a function of genomic and epigenomic factors. These studies focus on 500 mother-infant dyads drawn from two human studies (Montreal \& Hamilton). Assessment of maternal wellbeing and infant development (cognition, socio-emotional development, temperament, and brain structure) trajectories are undertaken from mid-pregnancy until 10 years of age. Genomic and epigenomic approaches were used to assess genetic vulnerability in these populations using a GWAS approach. This represents the first longitudinal study linking neurocognitive/behavioural function with structural neurodevelopment through neuroimaging and genetic vulnerability in humans, in the presence or absence of maternal adversity. The ability to identify postnatal events that serve to reverse a condition of vulnerability has enormous implications for the development of prevention /intervention programs reducing the future rates of a broad spectrum of chronic illnesses.

Our community sample consisted of mothers recruited in Montréal (Québec) and Hamilton (Ontario), Canada, at 13 to 20 weeks' gestation. Participants were part of the Maternal Adversity, Vulnerability, and Neurodevelopment (MAVAN) study, which examines the development of individual differences in phenotypes associated with multiple forms of psychopathology. Mothers were first assessed during their pregnancy (∼26 weeks) and then followed at multiple time points that included home visits and laboratory sessions.

Family Functioning Assessed Using the Family Assessment Device Questionnaire.
The Family Assessment Device (FAD) questionnaire assesses family functioning on each dimension of the McMaster Model of Family Functioning (MMFF) according to individual family member's perception of their family's functioning. In addition to the six subscales of the MMFF (Problem solving, communication, roles, affective responsiveness, affective involvement, behaviour control) the FAD includes a General Functioning scale that measures the overall level of the family's functioning. Sixty statements, geared to an eighth-grade reading level, describe various aspects of family functioning. Each member of the family over the age of 12 completes the pen-and-paper questionnaire by rating how well the statement describes his or her family. There are four choices (strongly agree, agree, disagree, strongly disagree) per item for each dimension. Dimension items are purposely not listed in consecutive order. Each item matches only one dimension and may describe healthy or unhealthy functioning.

Two scales termed 'care' and 'overprotection' or 'control', measure fundamental parental styles as perceived by the child. The measure is 'retrospective', meaning that adults (over 16 years) complete the measure for how they remember their parents during their first 16 years. The measure is to be completed for both mothers and fathers separately. There are 25 item questions, including 12 'care' items and 13 'overprotection' items.

Mother's sensitivity was assessed using the Maternal Behaviour Q sort (short version) and the Ainsworth scales (AINS). MBQS-S and AINS assess maternal sensitivity. Trained raters scored the mother's behavior on the scale for the MBQS and four scales of the AINS scales (Acceptance, Availability, Cooperation and Sensitivity) during a 20 and 30 minutes video-taped home mother-child interaction. The scales range from -1 to 1 for the MBQS and from 1 to 9 for the AINS scales, with higher scores indicating highly sensitive mothers on both instruments.

The Childhood Trauma Questionnaire (CTQ) is a 28-item self-report retrospective inventory intending to measure childhood or adolescent abuse and neglect, on a 5-point Likert scale ranging from Never True to Very Often True. The central constructs underlying the questionnaire are emotional, physical neglect and abuse, and sexual abuse. The CTQ contains five subscales : 3 subscales assessing abuse : Emotional, Physical, and Sexual abuse 2 subscales assessing neglect : Emotional and Physical neglect.

The Parental Authority Questionnaire (PAQ) investigates three prototypes of parental behavior: permissive, authoritative and authoritarian. Each prototype is measured on 10 items on a Likert scale from 1 (disagree strongly) to 5 (agree strongly). The questionnaire was developed to be answered by the child, however, it was adapted in order to let the mother rate her own prototype of parenting. Item scores for each scale were averaged to obtain a total prototype score, with high scores indicating that the mother rates herself to engage strongly in a given parenting prototype.

The Family Assessment Device (FAD) questionnaire assesses family functioning on each dimension of the McMaster Model of Family Functioning (MMFF) according to individual family member's perception of their family's functioning. In addition to the six subscales of the MMFF (Problem solving, communication, roles, affective responsiveness, affective involvement, behaviour control) the FAD includes a General Functioning scale that measures the overall level of the family's functioning. Sixty statements, geared to an eighth-grade reading level, describe various aspects of family functioning. Each member of the family over the age of 12 completes the pen-and-paper questionnaire by rating how well the statement describes his or her family. There are four choices (strongly agree, agree, disagree, strongly disagree) per item for each dimension. Dimension items are purposely not listed in consecutive order. Each item matches only one dimension and may describe healthy or unhealthy functioning.

Ran from Oct 2003 to primary completion in Dec 2017, 170 months.
Results were first posted in May 2020, 2 years 5 months after primary completion.
Of 460 non-industry observational studies under Depression, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 63. This study's 170 months is above that.
Counting every sponsor, half of 493 studies reached it within 33 months; a quarter within 13 and three quarters within 62.
