RR2.1: Marital Conflict and Children
This section provides research outlining the effect of one’s marriage on the quality of one’s parenting. Cummings and Davies have found that marital conflicts affect on children is not based on a one-time argument, but rather over a period of time. They wrote:

…However, the risk factor operates over time and insidiously, by altering family and child functioning over time.[i]

Arguments that are repaired satisfactorily and amicably with both parents being happy with the outcome actually have a positive impact on the children because it models for them how conflicts should be resolved. These are called constructive conflicts. However, the types of arguments that will have a much more negative impact on the children are those that are left unresolved over long periods of time, repeated heated and aggressive type of conflicts, and conflicts where one parent is being subjugated by the other. These are called destructive conflicts.

Unfortunately, sometimes we are not the best judge of whether our conflicts with our spouse are constructive or destructive. Often we lack the awareness to know how we come across to our children. As parents we tend to underestimate the effect of our conflicts with our spouse. Cummings and Davies’ research found that the children’s evaluation and response to a conflict is the best way to determine whether a conflict is constructive or destructive. Children’s responses include their emotional reactions as well as their coping mechanisms. So if a conflict is producing more positive responses than negative responses, then it is fair to classify it as constructive. If it is producing more negative responses than positive responses, then it would fall in the category of a destructive conflict. Based on this research, the following kinds of conflict have been found to be destructive.[ii]

  1. Physical aggression, involving swearing, insulting, throwing or smashing, or threatening to hit.
  2. Verbal hostility, which includes yelling as well as verbal threats.
  3. Non-verbal hostility, which includes withdrawal by husbands and/or wives, i.e., giving each other the silent treatment. This has been reported to have a negative effect on children’s behaviour and state of mind, including causing distress. One study showed that the children’s reactions to verbal conflict were similar to their reactions to non-verbal conflict. In fact, parents’ non-verbal reactions of fear caused more distress in the children than heated arguments.[iii]

One study showed that if apologies were accompanied by negative emotions, then it had a negative effect on the children.[iv] Another study found that children’s feelings of distress diminished when conflicts were resolved at an emotional level.[v] Another finding notes that conflicts which were not resolved but which were portrayed by parents to have been okay were found to have not been so beneficial to the children.[vi] Lastly, insecurity in children was caused equally by both a father and mother’s behaviour during conflict.[vii]

RR2.2: Effects of Marriage on a Child’s Well-Being
This is section provides research on the effects marital conflicts have on a child’s wellbeing, development and performance.

Marital conflicts diminish children’s school performances by undermining their capacity to sustain attention.31 When marital conflict increased, children’s emotional insecurity about inter-parental relations also increased and children’s sleep was disrupted.[i] Sleep problems were related to children’s behavioural, emotional and academic problems.[ii] Marital conflicts also caused disruptions in the children’s peer relationships, physical ailments, internalizing problems (such as kids becoming anxious, depressed, introverted and withdrawn) and externalizing problems (such as kids acting out, delinquency).[iii]

Children show responses to parental anger as early as 6 months old.[iv] Gottman says that the stress of living with parental conflict can affect the development of an infant’s autonomic nervous system, which, in turn, has an impact on the child’s ability to cope. While it is true that babies do not know the content of the parents’ arguments, they are able to sense that something is wrong.[v]

Hetherington describes the first two years following a divorce as a time of serious disruptions to parent-child relationships. Divorce and conflicts leading up to a divorce can cause parents to be depressed, distracted and exhausted, which can prevent them from being effective disciplinarians.[vi] Difficulty controlling and monitoring children’s behaviour is the most sustained parenting problem faced by divorced mothers.

RR1.1: Adolescent Well-Being Is Strongly Related to the Quality of the Parent-Child Relationship
In 2002, Child Trends looked at 1,100 research articles to identify what promotes positive adolescent development. They found that the parent-child relationship is strongly related to adolescent well-being. Here were their four key factors:

  1. Relationships – Teens who have warm, involved, and satisfying relationships with their parents are more likely to do well in school, be academically motivated and engaged, have better social skills, and have lower rates of risky behaviour than their peers.
  2. Modelling – Teens whose parents demonstrate positive behaviour on a number of fronts are more likely to engage in those behaviours themselves.
  3. Monitoring / Awareness – Parents who know about their children’s activities, friends, and behaviour and monitor them in age-appropriate ways have teens with lower rates of risky physical and sexual behaviour.
  4. Approach to Parenting – Teens whose parents are supportive and caring, but who also consistently monitor and enforce family rules are more likely to be motivated and successful at school, as well as psychologically and physically healthy. In contrast, adolescents whose parents are overly strict and do not give them any independence are more likely to engage in risky behaviour. Similarly when parents are warm but permissive, adolescents tend to be impulsive and engage in more risky behaviour.[i]

RR 1.2: Unhealthy Parenting Promotes Mental Illness
A group of researchers looked at 593 families and their children from two counties in the state of New York in 1975, 1983, 1985 to 1986, and 1991 to 1993, made up of parents with and without mental illness. Their aim was to examine the association between parents’ mental health, unhealthy parenting behaviour, and off-spring mental health. One of their findings was that the children who developed mental illness (depression, anxiety disorder, substance abuse, personality disorder, ADHD, panic disorder, social phobia, OCD, antisocial personality disorder and PTSD) did so primarily because of unhealthy parenting, not because of their parents’ mental illness. Thus, the higher the level of unhealthy parenting, the higher the frequency of mental illness in their children.[ii] Most parents would probably assume that mental illness passes down genetically, but that is not always the case. Dr. Charles Whitfield highlighted this and many similar studies, done primarily since the 1980s, asserting that the devastation of unhealthy parenting has only surfaced by way of empirical evidence as time moves on.[iii]
