In the DSM-5-TR (the manual professionals use to diagnose disorders), OCD is grouped with related disorders including Body Dysmorphic Disorder (obsessing over perceived flaws in appearance), Hoarding Disorder (difficulty throwing things away leading to clutter), Trichotillomania (compulsively pulling out hair), and Excoriation Disorder (compulsively picking at skin) because they all involve repetitive behaviours or mental acts in response to intrusive thoughts or urges. Each disorder is described below.
Obsessive-Compulsive Disorder (OCD) is a serious mental health condition where children and teens have unwanted thoughts that keep coming back (obsessions) and feel they must do certain actions over and over (compulsions) to feel better. OCD is NOT just liking things clean and organized! It is a very serious and disruptive condition that interferes significantly with daily life.
Key Facts:
OCD affects 1-4% of individuals across all age groups
About half of all adults with OCD first had symptoms in childhood
Boys often develop symptoms earlier than girls
Early treatment greatly improves outcomes
What happens with OCD?
Individuals with OCD get "stuck" on thoughts that feel very important and scary. For example, if someone without OCD has a worrying thought about forgetting to lock the door, they might double-check once and move on. Someone with OCD can't stop thinking about it, worrying they forgot to check properly, and must keep checking over and over until it feels "right."
OCD is very serious and disruptive:
Unlike typical habits or preferences for order, OCD thoughts and behaviours:
Take up over an hour each day
Cause significant distress and anxiety
Interfere with school, friendships, and family life
Feel impossible to stop or control
Often make no logical sense even to the person
Myth: "Everyone is a little bit OCD."
Fact: Only 1-4% of people actually have OCD. Real OCD causes serious distress and takes up over an hour each day. Liking things organized is not the same as having OCD.
Myth: "OCD is just about being clean and organized."
Fact: While some children with OCD worry about germs, others have completely different fears like making mistakes, needing things to feel "just right," or worrying about saying something wrong. Some children with OCD are actually quite messy.
Myth: "Children can just stop if they try hard enough."
Fact: Children with OCD cannot simply "turn off" their thoughts or stop their behaviours. The urges feel overwhelming and stopping feels impossible or dangerous to them.
Myth: "OCD is caused by bad experiences."
Fact: OCD is a medical condition related to how the brain works. While stressful events can make symptoms worse, they don't cause OCD. Many children with OCD have had completely typical, happy childhoods.
Myth: "Children with OCD know their fears don't make sense."
Fact: Unlike adults, children often don't realize their worries are unreasonable. They may truly believe something terrible will happen if they don't do their rituals.
Academic Signs
Taking much longer than other students to complete work
Erasing and rewriting until paper tears or looks "perfect"
Reading the same sentence over and over
Getting "stuck" on tasks and unable to move on to the next activity
Asking the same questions repeatedly for reassurance
Extreme distress over minor mistakes
Behavioural Signs
Frequent bathroom requests (often to wash hands or avoid "contamination")
Checking doors, windows, desks, or supplies repeatedly
Arranging items in very specific ways
Tapping, touching, or counting in patterns
Avoiding certain areas, objects, or activities
Taking forever to get ready or leave the house
Social and Emotional Signs
Appearing distracted or "in their head"
Difficulty with transitions or schedule changes
Extreme distress when routines are interrupted
Fatigue (from mental exhaustion or medication effects)
Seeming oppositional when really overwhelmed
Social withdrawal or avoiding activities
Family-Specific Signs
Taking hours to complete homework or get dressed
Excessive handwashing (until hands are raw or bleeding)
Checking locks, appliances, or lights repeatedly
Needing to do things in exactly the right order
Asking family members to say or do specific things
Demanding constant reassurance ("Are you sure I'm safe?")
Creating family rules to avoid their fears
Having meltdowns when family routines change
Involving parents in checking or cleaning rituals
Hiding behaviours from family
First-Line Treatment:
Specialized therapy that helps children understand how OCD works and learn to "boss back" their worries (Cognitive Behavioural Therapy; CBT).
How Treatment Works:
Child and therapist create a list of fears from least to most scary
They start with easier challenges and work up gradually
Child learns that anxiety goes down naturally without rituals
Brain "retrains" to see feared situations as less dangerous
Family learns how to support treatment without giving in to OCD demands
Behavioural Intervention Examples:
Competing responses: Giving children something else to do with their hands during high-risk times (fidget toys, stress balls)
Gradual exposure: Slowly facing fears in a safe way with therapist support
Response delay: Waiting longer and longer before doing rituals
Environmental changes: Removing or limiting access to things that trigger behaviours
Positive reinforcement: Rewarding efforts to resist OCD, not just success
Family Involvement:
Parents participate in treatment to learn how to respond helpfully
Families learn to stop "accommodating" OCD (doing rituals or avoiding triggers)
Siblings may also need support and education about OCD
When Medication May Be Added:
For moderate to severe cases
Usually combined with therapy for best results
Should be prescribed by doctors experienced with childhood OCD
Higher Risk: Children with Autism Spectrum Disorder (ASD) or intellectual disabilities are at higher risk for developing OCD. Studies show that having Autism increases the risk of developing OCD by about 4-12 times compared to individuals without an Autism diagnosis. However, it is often challenging to recognize OCD in this population due to:
Communication difficulties:
Nonverbal or minimally verbal children cannot describe their obsessive thoughts
Overlapping behaviours:
Both ASD and OCD involve repetitive behaviours, making diagnosis complex
Different motivations:
Children with ASD may enjoy their repetitive behaviours (stimming), while OCD behaviours cause distress
Assessment difficulties:
Standard OCD measures weren't designed for children with autism
Key Differences:
Autism Repetitive Behaviours
Often enjoyable or soothing
May not want to stop
Serve sensory or emotional needs
May increase when happy/excited
OCD Compulsions
Cause distress and anxiety
Desperately want to stop but can't
Done to prevent feared outcomes
Increase when anxious/stressed
Warning signs include:
Sudden increase in frequency or intensity of repetitive behaviours
New behaviours that seem driven by anxiety rather than enjoyment
Aggressive reactions when behaviours are interrupted
Self-injurious behaviours related to the repetitive actions
Specific examples: Stacking shoes in piles repeatedly, arranging TV remotes in exact patterns, opening and closing doors/windows compulsively
Functional interference: Behaviours that suddenly prevent normal activities like eating, sleeping, or learning
Observing OCD in Nonverbal Children:
Rely on behavioural observations rather than self-report
Look for sudden changes in repetitive behaviours
Notice if behaviours seem driven by anxiety vs. enjoyment
Monitor for signs of distress when behaviours are interrupted
Consider if behaviours are interfering with daily functioning more than usual
Observable Compulsive Behaviours in IDD/Autism:
Since children with intellectual disabilities or ASD cannot always describe their obsessive thoughts, professionals must look for observable compulsive behaviours:
Ordering and Arranging:
Arranging objects (toys, cutlery, clothes) in very specific patterns
Insisting items be placed in exactly the same spot
Wanting chairs in fixed arrangements or using same chair/location
Needing to do activities or chores at exactly the same time each day
Checking and Touching:
Opening and closing doors, cupboards, or containers repeatedly
Touching or tapping items in predictable patterns
Taking specific numbers of steps forward then backward
Unusual sniffing of items that have no smell
Cleaning and Grooming:
Excessive hand washing or insisting on specific hygiene routines
Picking at skin, clothing, or loose threads compulsive
Needing grooming steps done in exact sequence
Hiding or hoarding objects inappropriately
Obsessive Speech Patterns in Verbal Children with IDD:
For children with some verbal abilities, repetitive speech can indicate obsessive thoughts:
Repeating the same question or sentence with identical wording
Asking questions repeatedly until getting a very specific reply
Talking excessively about particular people, objects, or events
Making repetitive comments about health, weight, or body concerns
Excessive focus on time, calendars, or scheduling
Expressing irrational fears about places, people, or activities
Modified Treatment Approaches:
Treatment may need significant modifications (visual supports, shorter sessions, more family involvement)
Focus on behavioural interventions rather than talk-based strategies
May require specialized therapists trained in both OCD and autism
Longer treatment timelines often needed
Environmental modifications may be more important than traditional exposure therapy
Behaviours take up more than 1 hour per day
Child is significantly distressed by their thoughts or behaviours
Major interference with school, friendships, or family life
Child expresses thoughts of self-harm
Family routines are severely disrupted
Child is avoiding normal activities due to fears
Raw or bleeding skin from washing or picking
Extreme distress over minor changes
Types of Professional Help:
Child Psychologists, Psychological Associates or Psychiatrists with OCD specialization
Clinical Social Workers trained in specialized OCD treatment
What to Look For:
Specific training in evidence-based OCD treatment for children and adolescents
Experience with pediatric OCD (ask directly about percentage of practice)
Willingness to involve family in treatment
Understanding of how OCD differs from other conditions
Familiarity with Autism/OCD comorbidity if relevant
Remember: OCD is treatable with the right help. Early intervention leads to better outcomes, and most children can learn to manage their symptoms effectively with proper treatment.
Hoarding Disorder is when children and teens have great difficulty throwing away or giving away items, even things that seem worthless or broken. Their rooms, and sometimes their whole home, become so full of stuff that they can't use the spaces normally. This is different from just being messy or collecting things - hoarding causes real problems in daily life.
Hoarding symptoms often start in childhood or teen years
Affects about 1.5-6% of the population
Often runs in families
Boys and girls are affected equally
Different from normal collecting or being messy
Common Hoarded Items:
School papers and assignments (even old ones)
Toys they've outgrown
Clothes that don't fit
Books and magazines
Art supplies and craft materials
Food containers or wrappers
Broken electronics or toys
Warning Signs:
Can't throw away homework or school papers from years ago
Room is so full they can't use their bed properly
Keeps broken toys or electronics "to fix someday"
Gets very upset when parents try to clean their room
Saves food containers, bottles, or packaging
Can't find important things because of clutter
Avoids having friends over because of embarrassment
How It Affects Daily Life:
Trouble sleeping because bed is covered with items
Can't do homework at their desk
Family arguments about cleaning
Embarrassment about their living space
Difficulty finding clothes, school supplies, or homework
Safety concerns (fire hazards, can't exit room quickly)
Normal Collecting:
Items are organized and displayed nicely
Child enjoys showing their collection
Collection doesn't take over living spaces
Can easily get rid of damaged items
Hoarding:
Items are scattered and disorganized
Child feels ashamed and hides the mess
Clutter takes over necessary living spaces
Great distress when items are removed
Specialized Therapy:
Cognitive Behavioral Therapy (CBT) adapted for hoarding
Helps children understand why they save items
Teaches decision-making skills about what to keep
Gradual practice with letting go of items
Family involvement is essential
Family Support Strategies:
Don't throw away items without the child's involvement
Start with small, less important items
Praise efforts to declutter, even small ones
Help create simple organization systems
Be patient - progress takes time
Living spaces can't be used for their intended purpose
Safety hazards (blocked exits, fire risks)
Family conflict is severe
Child is missing school due to inability to find materials
Health problems from unsanitary conditions
Child expresses thoughts of self-harm
Hoarding disorder is a real mental health condition, not laziness
Children can't just "clean up" on their own
Throwing away items without the child's consent usually makes things worse
Progress is slow but possible with proper treatment
Early intervention leads to better outcomes
If you have concerns about a child/student, ask for support from the School Team which includes a psychological service provider.
Body Dysmorphic Disorder (BDD) is a condition where children and teens spend a lot of time worrying that parts of their body are flawed, ugly, or not good enough. They see these "flaws" as much worse than they actually are, and other people usually don't notice them at all. BDD is NOT vanity or being self-centered; it causes serious distress and significantly interferes with daily life.
Key Facts:
BDD affects approximately 2% of adolescents
Symptoms typically begin around ages 12-13
Girls tend to worry about more parts of their appearance, particularly weight than boys do, while boys focus more on their muscles."
Often goes undiagnosed or is mistaken for other conditions
What Happens is someone has BDD:
Unlike normal concerns about appearance that all teens have, children with BDD can't stop thinking about their perceived flaws. They may spend hours looking in mirrors, trying to fix or hide the "problem," or avoiding mirrors completely. The distress is so intense they may avoid school, social activities, or even leaving their room.
Common Areas of Concern:
Skin (acne, scars, color, texture)
Hair (thinning, styling, color)
Nose (shape, size)
Face features (lips, eyes, teeth)
Body shape or size of specific parts
Muscles (not big enough, not defined)
Behavioural Signs:
Spending excessive time checking appearance in mirrors
Avoiding mirrors or reflective surfaces completely
Constantly asking others about their appearance
Excessive grooming, makeup application, or hair styling
Covering body parts with clothing, hats, or makeup
Comparing their appearance to others constantly
Taking many photos to check appearance
Avoiding social activities or events
Missing school due to appearance concerns
Academic and Social Impact:
Difficulty concentrating in class due to appearance worries
Avoiding participation in activities (sports, presentations)
Social withdrawal and isolation
Depression and anxiety about being seen by others
Refusing to attend school
Avoiding dating or close friendships
Family Impact:
Spending hours getting ready each morning
Frequent requests for reassurance about appearance
Meltdowns when forced to go out in public
Demanding family avoid certain activities or places
Excessive spending on beauty products or treatments
Treatment helps children learn that their view of their appearance is distorted. Evidence-based treatment for BDD includes:
Specialized therapy (Cognitive-Behavioural Therapy or CBT) focusing on changing thought patterns about appearance
Gradual exposure to feared situations (like going out without makeup)
Family involvement to stop providing reassurance about appearance
Treatment Goals:
Reduce time spent checking or fixing appearance
Increase participation in normal activities
Improve self-esteem and social functioning
Learn healthy coping strategies for appearance concerns
Treatment focuses on changing thinking patterns, not changing appearance
Immediate Concerns:
Spending more than 1 hour daily on appearance concerns
Missing school or activities due to appearance worries
Expressing thoughts of self-harm or suicide
Complete social isolation
Severe depression or anxiety
Requesting cosmetic procedures or surgery
Understanding Skin Picking (Excoriation Disorder)
What it is: Skin picking disorder involves repeatedly picking at skin, resulting in tissue damage. This goes far beyond normal occasional picking at a scab or pimple.
Common Signs:
Picking at face, hands, arms, or other body areas
Creating sores, scabs, or scars from picking
Spending significant time picking (often hours)
Picking to the point of bleeding or infection
Difficulty stopping even when aware of damage
Using tools like tweezers or pins to pick
Where Picking Occurs:
Face (acne, blemishes, dry skin)
Hands and fingers (cuticles, hangnails)
Arms and legs
Back or chest
Any area with perceived imperfections
Understanding Hair Pulling (Trichotillomania)
What it is: Trichotillomania involves repeatedly pulling out one's own hair, resulting in noticeable hair loss and significant distress.
Common Signs:
Pulling hair from scalp, eyebrows, eyelashes
Visible bald spots or thinning areas
Playing with, examining, or eating pulled hair
Increasing tension before pulling
Relief or satisfaction after pulling
These behaviours are hard to stop because they:
Provide temporary stress relief or calming sensation
Can become automatic habits
May help manage difficult emotions
Often increase during times of stress or boredom
Behavioural Strategies:
Fidget toys during high-risk times (watching TV, doing homework)
Wearing gloves or bandages to make picking/pulling harder
Keeping nails short to reduce damage from picking
Removing mirrors from certain areas temporarily
Creating barriers like wearing mittens at night
Examples of Competing Responses:
Squeeze a stress ball instead of pulling hair
Use fidget cube during high-risk times
Hold hands together or sit on hands
Apply moisturizer to hands when urge to pick arises
Comb or brush hair instead of pulling
Family Support:
Avoid criticism or telling child to "just stop"
Help identify triggers and high-risk times
Provide alternative activities during these times
Praise efforts to use coping strategies
Support treatment participation
Behaviours cause visible damage (bald spots, sores, scars)
Child has tried to stop multiple times but can't
Behaviours interfere with school or social activities
Child feels distressed or embarrassed about the behaviours
Secondary infections occur from picking
Child avoids activities due to visible damage
Treatment Success:
Most children can learn to significantly reduce these behaviours
Treatment focuses on building awareness and alternative coping skills
Family involvement greatly improves outcomes
Earlier intervention typically leads to better results
