The science behind forgiveness and how it affects our mental health

What is forgiveness?

On this week’s episode of the podcast, I talk about the power of forgiveness. It’s scientifically proven that forgiveness can affect our health. As mental health professionals, this has important impacts both personally and professionally. I have also included a downloadable PDF for you to give your patients to help you walk them through the act of forgiving.

As a therapist, when I say the word “forgiveness,” my patients can shut down if I don’t explain it properly. Why? Because just the need for forgiveness is proof that they have been wronged. When we are wronged, it can be hard to let go of that hurt. That’s why I wanted to start out by saying what forgiveness (and this episode) is not about.

Forgiveness is not:

  • It is not approving.

  • It is not excusing the action, denying it, or overlooking it.

  • It is not just moving on (particularly not with cold indifference).

  • It is not forgetting or pretending it did not occur.

  • It is not justifying or letting go of possibly needed justice.

  • It is not calming down.

  • It is not a bargain or negotiation.

  • It is more than ceasing to be angry.

  • It is more than being neutral towards the other.

  • It is more than making oneself feel good.

  • It is one step towards reconciliation, but it is different from reconciliation, which requires a sincere apology from all parties.  

  • It is not dependent on the one you forgive—that would give the other power to control you by keeping you in your bitterness. Consider Corrie Ten Boom, who forgave the Nazis after losing her family in the Holocaust, or Marietta Jaeger who, after her daughter was kidnapped and brutally murdered, was able to forgive. People can forgive, even when the person who wronged them is unknown or dead.

  • It is not a one time event, but may need to be repeated (sometimes the hurt comes back, sometimes you need to start every morning with forgiveness).

  • It is not a restoration of full trust (trust takes time to develop or to be reinstated).

So what is forgiveness?

The Definition of Forgiveness:

Forgiveness is a process. It involves allowing yourself to feel the negative emotions you justly have towards an offense, and really putting the wrong into words in a congruent and authentic truthful way. Then choosing to release it, either giving it to a higher power, or letting it go to a cosmic sense of justice, or earthly legal justice system, and then continuing the process until negative affect is replaced with peace, empathy and compassion. When someone forgives they no longer have a portion of their daily life consumed in negative feelings towards the person or situation.  

“People, on rationally determining that they have been unfairly treated, forgive when they willfully abandon resentment and related responses (to which they have a right) and endeavor to respond to the wrongdoer based on the moral principle of beneficence, which may include compassion, unconditional worth, generosity, and moral love (to which the wrongdoer, by nature of the harmful act or acts, has no right)”  (Enright, 2015).

Elliot (2010) cited Enright and Fitzgibbons (2000) and came up with two types of forgiveness:

Decisional forgiveness: the experience of granting forgiveness without eliminating the emotion, but in this, resentment may continue. It involves a cognitive model where therapist works with the client one time to make decision to forgive.

Emotional forgiveness: the patient must demonstrate changes in emotion and motivation toward their offender.

Studies show that:

Decisional forgiveness can reduce hostility, but it is only marginally effective in improving stress levels or emotional health (Elliot 2010 citing Baskin and Enright 2004, Worthington 2007). This means that emotional forgiveness is the goal of all forgiveness therapy.

What’s the most effective way to help our patients forgive?

Individual therapy that accomplishes Enright’s 4 phases over 20 encounters is “clearly most effective” way to actually accomplish forgiveness. (Elliot 2010 citing Lundahl 2008)

Why should we care about forgiveness?

Forgiveness isn’t a “nice thing to do,” it has real health ramifications that have been thoroughly studied, and it’s a fact that the act of forgiving can be a real change agent in therapy and long term health.

Here are the studies:

  • People who live with depression and a history of maltreatment have an upregulation of their inflammatory response compared to those with no history of maltreatment (Danese et al. 2007 as cited by Elliot 2010)

  • Unforgiveness is reflected in specific cortisol levels, adrenaline production, and cytokine balance (Elliot 2010 citing Worthington 2005)

  • Cause-effect relationship between pain and anger is similar to the anger-depression relationship. some studies show that just the anticipation of pain is associated with anger. (Okifuji 1999)

  • Chronic pain often arises from injury, or accident, thus anger is directed usually at the one responsible, or oneself. (Greenwood 2003)

  • General intensity of anger is important, but also specific targets of anger seem to be essential factors in understanding adaptation to chronic pain. Some research has shown that inward anger is more common in those with chronic pain vs. those individuals with different targets of anger. A study using the MPI (multidimensional pain inventory- a 60 item self reported inventory to assess different aspects of chronic pain) showed that 88 people endorsed anger at themselves and scored 0.38 on the anger inventory. Those that endorsed anger at other targets all scored below 0.30. Anger should be viewed as a multifactorial construct in chronic pain. (Okifuji 1999)

Specifically, in chronic low back pain, a preliminary study of 61 adult patients with chronic low back pain (31 recruited from pain and palliative clinic, and 30 recruited from community) showed patients with higher scores on forgiveness-related variables (‘current level of forgiveness’ as measured by Enright Forgiveness Inventory and ‘forgiveness self efficacy’ as measured by the Forgiveness Self-Efficacy Scale) reported lower levels of pain, anger, and psychological distress.

Patients who scored  (Carson 2005) analysis revealed that “state anger largely mediated associations between forgiveness variables and sensory pain, whereas the association between current forgiveness and affective pain was mostly independent of state anger.”

What is bitterness?

When someone continues to hold on to unforgiveness, they can become what we would call “bitter.” Bitter people are exactly like that word describes—so steeped in resentment that they become unpalatable.

Clues that someone may be bitter:

  • Do they continually replay past hurts over and over?

  • Do they hold onto the pain?

  • Do they try to avoid someone?  

  • Do they quickly get angry with someone?

  • Do they speak trashfully or verbally malign someone?

  • Do they find that their bitterness is more associated with the proximity of the person who wronged them than the magnitude of the event?

  • What percent of their emotional energy is spent on this topic?  

* Recurrent resentment affects all relationships and takes up room in one’s emotional life.

What does research say about bitterness?

  • Ten years or more after a divorce, ½ of women and ⅓ of men are still intensely angry at their former spouses, and anger becomes an ongoing, dominant presence in their children as well (Wallerstein).  

  • Forgiving people have been found to have a lower blood pressure at baseline. (Larsen 2012)

  • “Recalled experiences of betrayal that were less forgiven were associated with greater cardiovascular reactivity as indexed by greater diastolic blood pressure, mean arterial pressure, and rate-pressure product…higher trait forgiveness was negatively associated with lower resting blood pressure and better post-stress recovery.” (Lawler 2005 citing Lawler 2003)

  • Those who measured high in hostility, 20-25 years later, had higher rates of heart disease (Shekelle 1983, Barefoot 1983).

  • When discussing the narrative of injustice, those with an understanding of forgiveness showed less anger expressions (Tina Huang, “Cross Cultural and Real-Life Validation”).

How can someone forgive?

If the previous studies about the negative effects of not forgiving aren’t enough, let’s look at some of the positive effects of forgiving.

Personal health results of forgiving:

  • Changes anxiety into inner peace, reduces symptoms of depression, anger, and paranoia (Dr. R. C. Hunter, 1978).

  • Genuine acts of forgiveness lead to overall improvement in the person’s emotional maturity and increases the capacities for courage, nurturance of others, and love (Dr. Morton Kaufman “The courage to forgive” 1984).

  • Reduces fear. Impulses of anger and revenge subside and are replaced by more appropriate expressions of anger (Dr. Richard Fitzgibbons).

  • Hypertension may be reduced (Huang 1990).

  • Patients with fibromyalgia who were taught forgiveness education had a significant decrease in symptoms (Lee, 2014).

  • Incest survivors showed significant improvement after a 1 year forgiveness education process (Robert Enright, 1994, 1995).

  • A study that looked at 20 psychologically abused and divorced women, some who had remarried and some who had not. All participants scored above 41 on the Psychological Abuse Survey was considered indicative of a present and serious pattern of emotional abuse. Randomized between forgiveness therapy (FT: based on the Enright model) with an alternative treatment (AT: anger validation, assertiveness, interpersonal skill building). The study found that the FT group showed a greater improvement in forgiveness, self-esteem, state anxiety, trait anxiety, depression, environmental mastery, finding meaning, post-traumatic stress symptoms all determined by pre-and post surveys and questionnaires. The FT group had an effect size of 1.79 and represents a shift from below normal levels to normative levels. (Reed 2006)

Spiritual Connection

Some patients highly value their higher power. You can ask them to turn to their spiritual power and ask for the grace to have the willingness to forgive. They can give the spiritual power the opportunity to work in their lives in that way. Some have had powerful forgiveness experiences with their higher power.

Steps in the process of forgiveness:

How can we help our patients forgive those who have wronged them? Sometimes our patients have experienced things that can hurt to even hear about. Helping them move from trauma and anger into a place of forgiveness so they can live a healthy emotional life can be difficult to navigate. But, it is a worthy journey to pursue.

Here are the steps I walk through with my patients using a workbook sheets I have created. I have included a FREE DOWNLOADABLE PDF below that you can give to your patients to fill out. It walks them through the steps in detail, giving them a drawing to fill out and journaling exercises with specific questions to answer that will help them process their trauma and grief.

How to treat violent and aggressive patients

On this week’s episode of the podcast, I interview Dr. Michael Cummings. Dr. Cummings works at a state psychiatric hospital for the criminally insane, so he has extensive experience in treating patients for aggression and violence.

The different types of aggression

The words “aggression” and “violence” are sometimes used synonymously, but in reality, aggression can be physical or non-physical, and directed either against others or oneself. Violence is more of a use of force with an intent to inflict damage.

One study looked at the principle types of aggression and violence that occur in psychiatric patients, and broke it down into three categories:

  • Impulsive violence (the most common category)

  • Predatory violence (purposeful and planned violence)

  • Psychotically-driven violence (least common)

Within 5 state hospitals, 88 chronically or persistently violent patients with 839 assaults, the rate of impulsive violence was 54%, and predatory violence was 29%. Psychotically driven patients logged 17% of total violence (Meyers, M. Cummings et al., 2013). Studies show psychotically driven violence decreases the longer the patients are in care and medicated.

Predatory Violence

Predatory violence is what people typically think of when they think of psychopathy, or someone with antisocial personality disorder. It is violence with a purpose, and that purpose is usually to gain something. They typically show a lack of fear and very little autonomic arousal even when they are being violent.  The amygdala and the temporal lobe is underactive and the communication between them has a weak signal. People with predatory violence also have lower affective empathy.

Some of the early research done by Adrian Reign measured blood pressure, galvanic skin response and heart rate when showing neutral, frightening or peaceful pictures to children. Of those who lacked effective response or autonomic response to those pictures, 75% percent of those individuals became violent criminals by age 18. Interestingly, 25% of them became prosocial and entered jobs as police officers, bomb disposal experts, and so forth.

True psychopaths are a very tiny part of the population. About 2% of women score significantly on the psychopathy checklist. About 2-4% of men have elevated scores on the psychopathy checklist. Not all of those individuals, however, are violent, and many persons who are psychopathic are more interested in profit. Some become the crime bosses (not actually doing the violence themselves) and others end up in politics.

Impulsive violence

Impulsive violence or aggression is actually the most common, and in many ways the most complex, form of violence that occurs in a variety of mental illnesses, including:

  • psychosis

  • mood disorders

  • personality disorders

  • anxiety disorders

  • PTSD

It is essentially an imbalance in impulse generation and a failure of the prefrontal cortex to evaluate the impulse and weigh the consequences. All of us generate a variety of impulses, some good and some bad, including impulses driven by our irritability and anger.

In predatory aggression there is increased medial prefrontal cortex activity whereas in reactive aggression there is decreased activity.

What can cause impulsive violence to be an issue:

  • Traumatic brain injury

  • Some of the dementias including frontotemporal dementias

  • Anoxic brain injury

  • Intellectual disability

  • Personality disorders

  • Drugs

  • Drug detox

Psychotic aggression

Psychotically driven aggression is most often a result of delusional ideation or the belief the person holds that they are in some way being persecuted and being taken advantage of. Psychotic or mentally ill people do have an increased rate of violence compared to the general population. The mentally ill are responsible for around 5% violent crimes, meaning non mentally ill people are responsible for 95%.

Psychotic Delusions leading to violence

Ones study looking specifically at the first episodes of psychosis found that in about 458 patients, anger was associated with certain types of delusions that led to the violence (Coid, 2013).

The underpinnings of delusion-driven violence usually stems from when people have delusional beliefs that are persecutory in nature. When they believe that someone is out to get them, it removes inhibitions against acting out violently, because that person’s view is they are protecting themselves. Typically, this violence comes from the belief they are being spied on or persecuted.

Persecutory delusions associated with a command hallucination is a particularly potent precursor to violent behavior. If your delusion tells you your neighbor is the devil, and your command auditory hallucination is that God is telling you to “kill him and save the world from destruction”  it can lead to a very bad outcome.

IQ and aggression

There is also an association between the IQ and aggression (Huesmann, 1987).

A recent study in state hospitals looked at what correlated with persisting violence, and across all of the types of violent behavior, cognitive deficits (particularly impairments and executive functioning) were associated with elevated rates of violence.

Men are more violent than women

Men are likely more violent than women because they have historically been the hunters, which involves violence. Women were gatherers more often than not, and consequently, men have a standing evolutionary tendency toward more frequent use of violence. Women can be violent, but if you look at the rates of violence between men and women, men are clearly more violent.

The purpose of aggression  

You could say the healthiest outcome for our aggressive and violent impulses is when we use our innate ability to be aggressive to engage in things like a healthy competition. Or even to provide motivation and drive to achieve.

In the beginning, humanity formed tribes, and aggression allowed someone to climb up the dominance hierarchy within the tribe. It also allowed them to protect themselves from other tribes. It was basic for survival.

If we look at animal psychology, there is a lot we can learn about the aggression and dominance hierarchy, like how apes interact with each other, or form alliances. As a way of creating alliances, often an alpha ape will groom other males.  The violence comes out when the clans come against each other. When one ape is wandering from its clan, two apes from another clan may attack one single ape viciously.

In other circumstances, if a dominant ape is taken away from his clan for a couple of days and brought back into the clan, a couple of other apes may have formed a new alliance against the prior leader and attack him.

As human beings, we are also like this. Many of our social interactions and group structures have the same kinds of alliances and effects of absence can play out similarly. Of course as humans, we do have higher verbal centers, and philosophy or spirituality, that allows an individual to be less violent and to transcend their base instincts.

Aggression and autism

People with intellectual challenges most often exhibit impulsive violence, particularly those on the autistic spectrum. The person may have a greater difficulty processing or understanding their own emotions if there are significant intellectual deficits. They may also have elements of not being able to judge a response or to moderate a response. The general pathophysiology of the autistic spectrum disorder suggests that the connections between neurons and the autistic brain is not what it should be, and they are not differentiated so that information processing can be fragmented.

Treatment of aggression

Psychotic aggression treatment

Treating with an antipsychotic medication is helpful and decreases violent episodes. In one study, clozapine helped psychotic aggressive patients with executive dysfunction more, compared to using haldol or olanzapine (Krakowski, 2011).   

Psychopathic aggression treatment

A predatory-violent individual needs to be contained in prison if there is a demonstrated past of persistent violence.

There is evidence that by enhancing intellectual empathy, psychopaths will be less violent. There is also interesting research that by giving oxytocin, the hormone that increases affiliation and collaboration, may have a moderating effect on some psychopathic individuals.

However, in terms of psychopharmacology, we don’t have any specific medications to control that behavior. Some medications, such as clozapine, can affect the underlying issues behind psychotic behavior and thereby reduce it, but there is no direct treatment for psychopathic violence pharmacologically.   

Impulsive aggression treatment

Dr. Cummings discussed the use of Mood stabilizers helping in persons with borderline personality disorder, SSRIs and trazodone helping in dementing illness in the elderly and alpha 2 agonists in people with things like autism or TBI. Alpha 2 agonists (clonidine) can fool the brain stem into thinking enough norepinephrine has been released, then less norepinephrine is secreted, making the brain stem calm down.

Essentially, in an emotional disorder, if you change the affective (limbic) tone, you can decrease the likelihood of emotionally reactive aggression, for example, by using mood stabilizers lithium and divalproex.  

Using an antipsychotic, and not just a mood stabilizer, doesn’t show any benefit for traumatic brain injury patients. Antipsychotics have been used for people with autism spectrum disorder, and some evidence shows that drugs like risperidone can be helpful to control outburst issues. If there is evidence of sexual aggression (or aggression occurring at women after puberty), using an GnRH agonist—antiandrogen treatment—can sometimes be necessary).

Psychotherapy for aggression

There have been a number of anger management therapies that have been used over time. Therapists can help people be aware of their anger and manage their impulses, or push their anger and aggression toward a more prosocial response.

For people with borderline personality disorder, dialectical behavioral therapy, mentalization based therapy or transference therapy are important. For schizophrenic patients, a good therapeutic alliance is important to create medication compliance. I have touched on how to process anger in my microexpression series and will have future episodes focusing more on the psychotherapy approaches to anger.  

Overall in therapy, we must assume that our patients will lie to us sometimes because they are afraid, and double check to insure they are following our prescribed protocol. We must also work hard to build trust and a therapeutic alliance.

Final Thoughts

Violence and aggression deserve much more attention as a specialty than we have given it in the past. It is a major burden for family members and friends.

Please submit any questions you have and we will submit them to Dr. Cummings and to answer.

(In the podcast details about specific medications are discussed for psychiatrists who are interested in advanced psychopharmacology.)
