Abuse is often categorized into different forms. While some are fairly well known, others are rarely discussed outside of anti-violence activism and the like. In addition, many people are unaware of how various kinds of abuse are defined and what actions are considered abusive. Here’s a list to help make things a bit clearer. Please note that some actions are abusive in multiple ways and this list likely won’t be able to describe every abuse behavior. In addition, this list is designed to be as generic as possible so it can be applied to a variety of different situations rather than exclusively focusing on romantic partnerships, parent-child relationships, friendships etc. 

Emotional abuse: 

Far more than ‘hurting someone’s feelings’, emotional abuse is a devastating form of abuse which can affect an individuals self worth, feelings of safety, and quality of life. It can even lead to mental health issues. While often dismissed as a ‘less serious’ form of abuse, the impact of emotional abuse can be devastating and last for a long time.
Behaviors include;

• Frequent, excessive and unwelcome criticism (as opposed to constructive criticism which is asked for and given in to help. Some people will claim their emotional abuse is actually meant to be constructive criticism, however, if its not requested and related to a specific thing a person is doing, then chances are, this is a lie)
• Put-downs and name-calling (this is also verbal abuse)
• Controlling the victim
• Invalidating their feelings and experiences
• Withholding (this includes ‘the silent treatment’, refusing to listen, and withdrawing emotionally)
• Excluding the victim
• Telling the victim that their thoughts, feelings, ideas, interests etc are wrong/bad/silly

Physical Abuse

One of the more well known forms of abuse, people often think that physical abuse is limited to romantic partnerships where one person hits, punches or attacks the other. While those behaviors are physically abusive, violence is not limited to contact that causes injury or even physical contact, and it can occur in any relationship.
Examples of physical abuse include

• Hitting, slapping, pinching, hair-pulling, biting, scratching, choking
• Pushing, shoving and grabbing
• Standing over someone to intimidate them
• Blocking a doorway or exit
• Any and all unwanted and non-consensual physical contact
• Throwing objects (whether at the victim directly or elsewhere)
• Breaking your possessions
• Threatening violence
• Threatening with a weapon (such as pointing a knife or gun at the victim)
• Forcing you to make eye contact with them
• Driving wrecklessly/dangerously while the victim or victims children or pets are in the car
• Harming the victims pets
• Forcing the victim to eat or not letting them eat
• Not allowing the victim to sleep
• Locking the victim in/out of the house
• Denying the victim access to medication
• Not allowing the victim to use the toilet or meet other physical needs

Psychological Abuse

Emotional and psychological abuse are often discussed together as emotional abuse since there is a lot of overlap. What affects us emotionally also affects us psychologically. It can still be helpful to distinguish the two sometimes. It’s also sometimes referred to as mental abuse.
Behaviors include

• Gaslighting; denying the victims experience and making them question their reality or perception, hiding the victims personal items then claiming the victim lost them, denying that something happened when it did, and more
• Invalidating the victim
• Calling the victim ‘crazy’, ‘insane’ 'psycho’, often when they confront the abuser about their behavior
• Minimize or dismiss the victims achievements
• Behaving in ways that cause the victim to feel intimidated or afraid
• Using the victims fears against them (e.g forcing you to hold a spider knowing you’re afraid of them)
• Behaving in erratic or unpredictable ways to make the victim feel scared of what the abuser might do
• Terrorizing the victim
• Subtle threats which communicate that the abuser is dangerous or intends to harm the victim e.g cleaning or playing with a weapon in front of them
• Using mental health issues the victim has to blame them for the abusers behavior or deny that that certain things happened
• Threatening suicide or self harm if the victim leaves or doesn’t do what the abuser wants
• Making the victim responsible for the abuser

Sexual Abuse

Sexual abuse is a broad term that is often thought of as forced sexual contact, however it also includes sexual behavior without touch. The behaviors below are sometimes related to age, for example, exposing a child to pornography is always sexually abusive whether or not the child wanted or asked to see it, whereas for adults, forcing the victim to watch pornography (whether by physical force or coercion) is sexual abuse.
Behaviors include

• Forcing the victim to engage in sexual activities (rape)
• Engaging in sexual acts in front of the victim
• Discussing sexual activities in front of the victim (especially children, by adults)
• Exposing the victim to sexually explicit media such as pornography (especially children, by adults)
• Threatening to force sexual contact upon the victim

• Threatening the victim with harm unless they perform certain sexual acts or give the abuser sexual access
• In the case of BDSM relationships and sexual interactions, ignoring one of the participants safe word
• In the case of BDSM relationships and sexual interactions, blaming the victim for not using a safeword in circumstances where it is not applicable and/or possible, e.g. the abuser initiated a BDSM scene without prior discussion or consent, or one party is unable to vocalize
• Engaging in sexual contact with someone in any situation where the other party has not given clear, enthusiastic consent
• Any situation where an adult engages in sexual contact with a minor
• Sharing photos of the victim in their underwear/nude/engaged in sexual contact without their consent, or threatening to do so
• Knowingly exposing the victim to STIs
• Interfering with the victims birth control or safer sex methods
• Deceiving the victim about the circumstances of sexual contact

Social Abuse

Social abuse is a less often discussed form of abuse where the abuser undermines the victims relationships and autonomy. Like other forms, behaviors here are often also applicable to other categories.
Behaviors include

• Not letting the victim see or speak to their friends and/or family
• Making the victim feel guilty for having other relationships (except in monogamous relationships where one person is dating other people/'cheating’)
• Going through the victims phone, emails, text messages. etc without their knowledge and/or consent
• Spreading rumors about the victim
• Telling the victim that their family/friends said things that they didn’t say
• Telling the victim that only the abuser really cares about them
• Manipulating the victim into confrontations with family/friends (e.g. encouraging them to raise an issue then withdrawing support during/after the confrontation)
• Outing the victim if they are LGBT+ 
• Telling other people about mental health issues the victim has
• Telling people about abuse the victim has experienced
• Telling people that the victim is abusive when it’s not true, or claiming they did certain abusive actions that they didn’t do

Spiritual Abuse

Spiritual abuse is another form of abuse that’s often left out of discussions but is still very important. While it’s generally thought of in a religious context, it can also be used against those who are not part of organized religions or do not have spiritual beliefs. In essence, it undermines a person’s spiritual beliefs, or lack thereof. 
Behaviors include

• A person in a position of authority excluding certain individuals, often on the basis of sexual/romantic orientation or transgender status but can also be due to ethnicity, gender, class, disability etc
• Shaming individuals for not paying tithing or giving money to a church/religious/spiritual organization/group

Hopefully I have covered most kinds of abuse here, however I will certainly add to this if I’ve missed anything. I know it’s a long post, but if you would be able to share this to raise awareness, I would really appreciate it. Many people are aware that abuse happens but far less people know how abuse is defined. This is not a complete list but I hope that it can serve as a guide to those wondering if what they are experiencing is in fact abuse.
