How to Identify the Hidden Function of Any Symptom

We approach a symptom as a purposeful maneuver within a social system rather than an internal malfunction of the individual. When a client presents with a repetitive behavior that seems irrational or painful, we do not ask why they are doing it in a historical sense. We ask what the behavior achieves in their current relationships. Jay Haley taught us that a symptom is a strategy for controlling a relationship when other methods of influence have failed. The symptom acts as a contract that defines how people must behave toward the sufferer. It functions as a communication, a protective shield, and a mechanism for keeping a family system stable. We must understand these functions before we attempt any intervention, because a symptom that serves a vital purpose will resist every effort at change until that purpose is met by other means.

I once worked with a thirty-four-year-old man who suffered from severe hand tremors that only appeared during dinner with his wife. He was a successful architect who had no neurological issues, yet his hands would shake so violently that he could not hold a fork. We observed the sequence of the meal. When his hands began to shake, his wife would immediately stop talking about her stressful day at the office. She would lean toward him, cut his meat, and speak to him in a soft, soothing tone. The tremor was not a medical problem. It was a communication that forced the wife to cease her complaints and offer care. It was also a power maneuver. By being helpless, the husband gained total control over the conversation and the physical actions of his wife. You will see this dynamic often. The person with the symptom appears to be the most miserable member of the group, yet they are the person who determines the behavior of everyone else in the room.

We identify the communication function by looking at the effect the symptom has on the people surrounding the client. You must watch for the immediate reaction of the spouse, the parent, or the employer. If a child develops a sudden stomach ache every morning before school, you do not look for the source of the pain in the child’s stomach. You look for what happens between the parents when the child stays home. I recall a case where a ten-year-old boy had chronic abdominal pain that kept him out of the classroom for three months. When he was home, his parents, who were on the verge of a divorce, stopped fighting. They had to cooperate to care for their sick son. They shared the task of taking him to specialists and discussing his diet. The boy’s pain was a message to the parents that they must stay together. It was a protective function. The child sacrificed his education and his physical comfort to prevent the collapse of the marriage.

You must be precise when you interview the family about the sequence of the symptom. Do not ask for their opinions on the cause. Opinions are usually wrong and full of theory. Ask for the play-by-play description of the last time the symptom occurred. You ask: who was the first person to notice the behavior? What did that person say? What did the client do next? What did the third person in the room do? You are looking for a circular chain of events. We call this the homeostatic loop. The system wants to stay the same even if the current state is miserable. The symptom is the thermostat that keeps the temperature of the relationship from changing too much.

I worked with a woman who had severe depression that made it impossible for her to leave her bedroom. Her husband was a high-functioning executive who was rarely home. When she became depressed, he had to cancel his business trips and work from his home office. If she felt better, he went back to the airport. Her depression maintained the homeostasis of their marriage by ensuring his presence. We do not view this as a conscious choice or malingering. The woman genuinely felt incapacitated. However, the system required her incapacity to function. If you simply cured her depression without reorganizing the marriage, the husband would leave, or he would develop a symptom of his own to bring her back into a caretaking role.

When you identify a protective function, you are seeing a client who is being helpful in a harmful way. They are using their symptom to take care of someone else in the hierarchy. A common example is the rebellious teenager who gets arrested for shoplifting just as his father loses his job. The father, instead of sinking into his own despondency over his unemployment, becomes energized by the need to deal with the legal system and his son’s behavior. The son is being a delinquent to give the father a sense of purpose. We see this often in families where one member is fragile. Another member will become the problem to provide a distraction or a common enemy.

You must investigate the hierarchy of the system to find the hidden function. In a healthy system, the parents are in charge and the children are below them. Symptoms often appear when this hierarchy is inverted. I once saw a family where a seven-year-old girl would refuse to eat anything but white bread. The mother would cry and beg her to eat vegetables. The father would yell at the mother for being weak. The girl was effectively the most powerful person in the house. Her refusal to eat was a maneuver that put her above both parents. It also allowed her to control the conflict between them. By focusing on the bread, the parents did not have to focus on their own lack of intimacy. The symptom was a tool for dominance that simultaneously protected the parental union.

We use the observation of these functions to design an intervention that provides the same benefit without the cost of the symptom. You do not tell the family what you see. If you tell a mother that her son’s asthma is keeping her from leaving an unhappy marriage, she will become defensive and the symptom will likely worsen to prove you wrong. You instead use a directive. You might tell the mother and father that they must spend two hours every night behind a closed door discussing their child’s health. This forces them to have the intimacy they are avoiding while keeping the child out of the room. You have moved the function of the symptom into a task.

I remember a young man who could not stop washing his hands. He was twenty-two and lived with his widowed mother. Every time the mother talked about dating again, the hand-washing intensified. The function was to keep the mother occupied with his hygiene so she would not leave him. He was protecting himself from loneliness, and he was protecting her from the risk of a new relationship. You must look for these layers. To break the cycle, you do not talk about his anxiety. You give him a task that occupies his hands and involves the mother in a different way. You might instruct him to spend three hours a day meticulously cleaning his mother’s car as a way of showing his devotion to her, but he must do it only when she is not looking. This creates a new secret sequence that disrupts the old one.

We observe the timing of the symptom with professional detachment. If a client’s panic attack always happens on a Friday night, you look at what Friday night represents in their social schedule. Perhaps it is the night they are expected to visit their overbearing parents. The panic attack is a valid excuse to stay home without having to confront the parents directly. It is a polite way of saying no. You must see the symptom as a solution. It is the most effective solution the client has found for a difficult interpersonal problem. Your job is to find a more efficient, less painful solution that achieves the same systemic goal.

As you sit with the client, you are not looking for a diagnosis in a manual. You are looking for the choreography of the room. You watch for who looks at whom when the symptom is mentioned. You watch for the subtle smile on a parent’s face when their child describes a failure. You watch for the way a husband speaks for his wife when she tries to explain her pain. These are the markers of function. The symptom is a piece of a larger puzzle. When you see the whole picture, the symptom makes perfect sense. The logic of the system is always sound, even when the behavior of the individual appears chaotic. We do not fight the symptom. We learn its language so we can change the conversation. The client’s non-verbal response to your first directive will tell you if your assessment of the function is accurate. When you suggest a task that mimics the function of the symptom, the client will often exhibit a sudden, brief moment of clarity in their expression. This is the indicator that you have found the leverage point.

We transition from the identification of a leverage point to the analysis of the organizational hierarchy. Every symptom occurs within a structure where someone holds authority and someone else challenges it through indirect means. We see the family or the office not as a collection of individuals but as a set of hierarchical lines that have become crossed or tangled. When you observe a symptom, you are looking at a maneuver to reorganize that power structure. You must determine who is being protected and who is being controlled by the presence of the problem.

We define the perverse triangle as a situation where two people of different hierarchical levels form a secret coalition against a peer of one of them. You will see this clearly when a mother and son unite to undermine the father’s rules. I once worked with a family where the ten year old daughter began stealing from her classmates exactly three weeks after the father lost his job. On the surface, the problem was the daughter’s lack of impulse control. In reality, the daughter’s behavior forced the parents to unite in their worry for her. This shared concern prevented the father from falling into a depression and prevented the mother from expressing her anger at their financial instability. We call this a benevolent sabotage. You must see the theft as a service the child provides to the marital unit. The child’s symptom maintains the hierarchy by giving the parents a reason to stay in the superior position of caregivers rather than facing their own collapse.

We treat the symptom as a metaphorical statement about the social situation. When a client cannot swallow food, we look for what they are being forced to accept in their life that is unpalatable. I saw a man who developed a functional paralysis of his right arm. This man worked for a supervisor who demanded he sign fraudulent reports. By losing the use of his hand, the man avoided the moral crisis without having to confront the supervisor directly. His body solved the problem when his speech failed him. We do not offer an interpretation of this metaphor to the client. You never tell the man his arm is paralyzed because he is afraid of his boss. If you offer an interpretation, the client will deny it, and the symptom will likely intensify to prove the interpretation wrong. Instead, you use the metaphor to design your directive.

You provide a task that requires the use of the arm for a specific purpose. I told this man that his arm required a particular type of exercise to regain its strength. I instructed him to use that hand to write a detailed log of every instance where his supervisor showed a lack of integrity. He had to do this for two hours every night. This task forced him to use the hand and it forced him to document the very conflict the paralysis was hiding. Within four days, the paralysis vanished because the task of documenting the supervisor was more burdensome than the prospect of confronting him. We observe that when the cost of the symptom exceeds the benefit of the protection it provides, the client will find a way to recover.

We use the concept of the ordeal to make the symptom more difficult to maintain than it is to give up. For an ordeal to work, the task must be something the client can do, something that is good for them, and something that is neutral or unpleasant. If a client complains of insomnia, you do not suggest relaxation. You instruct the client that every time they find themselves awake at two in the morning, they must get out of bed and wax the kitchen floor. They must continue waxing until the sun rises. The act of waxing a floor is a productive activity, but it is also exhausting. The client soon discovers that falling asleep is preferable to the labor of cleaning. You are not asking for an act of will. You are creating a situation where the symptom no longer serves a protective or controlling function because the price of the behavior has become too high.

I once treated a man who suffered from debilitating stomach pains every Friday evening. These pains began precisely at five o’clock and lasted until Sunday night. When we examined the sequence, we discovered that his mother in law arrived for a weekend visit every Friday at five thirty. The man felt he could not tell his wife that her mother stayed too long or interfered with their parenting. His stomach pain provided a solution. Because he was ill, the wife had to spend her weekend caring for him in the bedroom, which meant she could not spend that time entertaining her mother. The mother in law eventually stopped coming as often because the house was a place of sickness and gloom. The symptom protected the marriage from the intruder while allowing the husband to remain a non confrontational son in law. We identify this as a successful but expensive maneuver. You must help the client find a way to set that limit without needing to be physically incapacitated.

In strategic therapy, we view the symptom as an attempt to define the status of a relationship. If a wife develops a sudden phobia of driving, she gains the power to determine where the couple goes and when they leave. I worked with a couple where the wife refused to drive on highways. The husband was a high ranking executive who was forced to leave his office early every day to chauffeur her to her appointments. On the surface, she was the helpless one and he was the powerful provider. In reality, her phobia allowed her to dictate his schedule and humble his professional standing. We see this as a reversal of the overt power structure. You do not address the fear of driving. You address the fact that the husband has no say in his own calendar. You might direct the husband to choose three nights a week where he stays late at the office, regardless of her appointments, while she must find an alternative way to travel. When the husband asserts his position, the driving phobia often ceases because it no longer serves to equalize the power dynamic.

We look for the person who is most inconvenienced by the symptom. That person is usually the one who has the most power to change the system. If a child refuses to go to bed, you do not focus only on the child. You look at which parent is being rescued from an unpleasant conversation with the other parent by the child’s resistance. I worked with a couple who had not had an intimate conversation in three years. Their youngest son developed a habit of waking up having nightmares every night at ten o’clock. The mother would then spend the rest of the night in the son’s bed. This arrangement protected the parents from the tension of their own bed. To change this, you must give the parents a task that requires them to cooperate in a way that bypasses the child. You might instruct them to sit together in the kitchen from ten o’clock until midnight to discuss their financial goals, while the child is kept in his own room by a hired sitter. By removing the child’s function as a buffer, you force the parents to deal with each other.

You must be prepared for the system to resist your intervention. When you begin to move the hierarchical lines back to their proper places, the symptom will often get worse before it gets better. This is the homeostatic pull of the system. We expect this. I once told a mother to stop helping her twenty year old son clean his room, even though she complained he was a hoarder. When she stopped, the son did not clean. Instead, he began leaving trash in the hallway. The mother panicked and wanted to return to her old habits. You must encourage the mother to stay the course. You tell her that the trash in the hall is a sign that the son is finally taking responsibility for his own mess, even if he is doing it poorly. You are reframing the resistance as progress.

We use the one down position to reduce the client’s need to fight us. If you act as the all knowing expert, the client will use their symptom to prove you wrong. If you act slightly confused or uncertain, the client will often work harder to prove they can change. I might say to a client that I am not sure they are ready to give up their anxiety yet. I might suggest that the anxiety is still providing some benefit we do not fully understand. This maneuver puts the client in a position where the only way to assert their power over me is to get better. You are using the client’s need for control to fuel their recovery. We observe that the most effective directives are those that allow the client to feel they have outsmarted the person giving the instruction.

We use the paradoxical directive when a client presents a symptom that they claim is beyond their voluntary control. If you tell a client to stop a behavior they cannot stop, you have failed. If you tell a client to continue the behavior, you have moved the symptom into the social contract between the two of you. We call this prescribing the symptom. When you prescribe a symptom, you change its function from an involuntary affliction to an assigned task. I once worked with a middle aged man who suffered from a severe facial tic that occurred every time he spoke in public meetings. He had tried to suppress it for ten years without success. I did not ask him why he had the tic. I did not ask about his childhood. Instead, I instructed him that for the first five minutes of every meeting, he must purposely exaggerate the tic so that every person in the room could see it clearly. He was to do this as a way of testing the observational skills of his colleagues. By the time he reached the third minute of his first meeting after our session, he found he could not produce the tic at all. Because I had ordered him to do it, the tic could no longer serve as a way for him to express anxiety while claiming he was not anxious. He had to decide to be anxious, which is a contradiction that most people cannot maintain.

You must deliver a paradoxical instruction with absolute conviction. If you hesitate or show any sign that you are being clever, the client will perceive the trick and the intervention will fail. We categorize these clients as “help rejecters” who use their symptoms to prove that no authority figure can change them. You use their need to win against you as the engine of their recovery. When you tell a resistant client that they must not change too fast because their system is not yet ready for the consequences of health, you are placing them in a therapeutic double bind. If they agree with you, they are following your instruction, which means you are in control of the pace of therapy. If they disagree with you and get better quickly to prove you wrong, they are cured. In either scenario, the symptom loses its power to organize the relationship. I used this approach with a woman who had spent fifteen years in various clinics for chronic depression. I told her that her depression was the only thing holding her marriage together because it gave her husband a reason to feel superior. I instructed her to remain depressed for at least three more months to ensure her husband did not have a nervous breakdown from the sudden loss of his role as a caretaker. She returned two weeks later, angry and energetic, claiming she had decided to get well regardless of my concerns for her husband.

We use metaphorical communication when a client is too guarded to discuss a problem directly. You talk about a different area of life that shares the same formal structure as the problem. If a couple is having a conflict over sexual intimacy, you do not need to talk about the bedroom. You can talk about how they eat dinner. You can ask them who decides on the menu, who prepares the food, and who cleans up the mess. You then give them a directive regarding the meal. I once had a couple who could not agree on how to discipline their child. Every time the father set a rule, the mother undermined it. Instead of discussing parenting, I talked to them about their overgrown garden. I instructed the husband to select one corner of the yard to clear of weeds, and I instructed the wife that she was not allowed to touch any tool or plant in that specific corner for seven days. By establishing a clear hierarchy and territory in the garden, we created a behavioral template that they naturally applied to their parenting.

You can also use the “pretend” technique when working with families where a child has a symptom. We assume the child is using the symptom to protect the parents or to keep them together. I worked with a seven year old boy who had nightmares every night. These nightmares forced his parents to stop their frequent late night arguments to comfort him. I asked the boy to pretend to have a nightmare on Tuesday and Thursday nights, even if he felt fine. I told the parents they had to pretend to believe him and comfort him just as they always did. This instruction makes the symptom a game. If the boy is pretending, the parents are not actually being rescued from their fight; they are participating in a staged drama. This breaks the homeostatic loop because the parents can no longer use the child’s “real” distress as an excuse to stop their own conflict. They are forced to see the behavior as a performance, which strips the symptom of its protective utility.

We observe that most symptoms are a way of communicating something that cannot be said in words. When you identify the hidden function, you must decide whether to make the function explicit or whether to change the behavior while leaving the function implicit. In strategic therapy, we usually choose the latter. You do not need the client to understand why they are doing something. You only need them to do something different. If a manager in a large company is constantly micromanaging his staff to the point of a revolt, he is often trying to manage his own fear of being replaced. You do not tell him he is insecure. You give him the task of finding one mistake per day that his staff makes and writing a three page report on why that mistake is actually a sign of creative risk taking. This directive forces him to look for the positive in the very things he fears, and it changes his relationship with his subordinates without him ever having to admit he was afraid.

As we move toward the conclusion of a successful intervention, we must prepare for the system’s attempt to return to its previous state. We call this the relapse. You do not wait for it to happen. You predict it. You tell the client that they have made excellent progress, but you are concerned that they might have a major setback in the next two weeks. You describe the setback in detail. You tell them they will feel the old familiar urge to use the symptom. By predicting the relapse, you take away its power. If the relapse happens, the client feels you are a genius who saw it coming, and they follow your next instruction. If the relapse does not happen, the client has once again proven you wrong by staying healthy, which is exactly what you wanted.

I once told a young man who had overcome a hand washing compulsion that he would likely feel the need to wash his hands sixty times on the following Saturday. I told him he should not fight it, but rather lean into it. On that Saturday, he started to wash his hands, remembered my prediction, and felt so annoyed by my accuracy that he stopped after two washes just to assert his independence. We must always remember that the client’s desire for autonomy is your greatest ally. You use your position as an expert to provide the resistance they need to push off of. We are not there to be their friends or their confessors. We are there to act as the strategic architect of a new social reality.

You must remain vigilant for the moment when the client no longer needs the symptom to solve their problem. This is usually marked by a change in the hierarchy of their primary relationships. The mother who was over involved with her son suddenly joins a bridge club or starts a business. The husband who was terrified of his wife’s anger starts to make jokes during their arguments. These are the indicators that the organizational structure has shifted. We do not need to celebrate these moments with the client. We simply acknowledge them and begin to withdraw. The final stage of any strategic intervention is the therapist becoming irrelevant. You know you have succeeded when the client believes they solved the problem themselves through their own common sense or a change in circumstances. We accept this lack of credit because our goal is the functional integrity of the system, not the validation of our own ego. A symptom is a sophisticated solution to an impossible social problem, and our job is to provide a simpler solution that costs the client less. The most stable systems are those where the power is clear, the boundaries are respected, and the members can communicate their needs without resorting to the theater of illness. We conclude a case when the client is once again capable of being an active participant in their own life. You will find that the most profound changes occur when the client is busy doing something else you told them to do. Clinical success is the quiet absence of the noise the symptom used to make. We see the family leave the office for the last time, and we notice that they are no longer looking at us for the answer, but are instead looking at each other. This shift in eye contact marks the restoration of the natural hierarchy.
