Learning objectives of this module
  • You can describe crisis intervention as a time-limited form of help focused on the current trigger, and distinguish it from psychotherapy and psychiatric treatment.
  • You know five guiding principles – prompt, low-threshold help, relationship, focus, activating resources and surroundings, safety – and can explain the reasoning behind them.
  • You can explain the BELLA mnemonic according to Sonneck et al. (2016) and use it to structure a plan of action for a crisis situation.
  • You can place social work within the chain of care and know that crisis services are a matter for the federal states – anchored in law in Bavaria, for example, but not available in a uniform way nationwide.
  • You reflect on the limits and tensions of crisis intervention and draw conclusions for your own practice in a team.

The first module was about what a psychosocial crisis is and how it can develop. This module changes perspective: what should social work professionals do when a person in an acute crisis is sitting opposite them, in despair on the phone or collapsing in the ward corridor? The answer is not a rigid programme but a stance guided by a few well-founded principles – and by a simple structure that stays available even under pressure.

PART 1 – Introduction: what crisis intervention is – and what it is not

Starting point: the crisis as lost balance

Crisis intervention builds on an understanding of crises. In the standard German-language literature, the psychosocial crisis is described, in essence, as the loss of emotional balance that a person experiences when confronted with events and life circumstances that they cannot cope with at the moment (Sonneck et al., 2016). Two features of this definition are decisive: first, the crisis is not a term for illness but describes a mismatch between strain and the coping resources currently available. Second, it is tied to the moment – the balance is lost, but not permanently destroyed. This is exactly where the task of crisis intervention comes from: it is meant to help restore a sustainable balance, ideally before the situation becomes entrenched or escalates.

The crisis concept on which this view rests goes back to Caplan. Sonneck et al. (2016) distinguish traumatic crises, triggered by sudden, serious events, from crises of change, which arise from life transitions and upheavals. For the traumatic crisis, Cullberg (1978) describes a course with shock, reaction, processing and reorientation phases whose transitions are fluid. This matters for action because the same intervention works differently in different phases: a person in shock first needs orientation and stability, not problem-solving steps.

Definition: crisis intervention

Here, crisis intervention is understood as time-limited, goal-directed support that starts directly from the current crisis, relieves and stabilises the person affected, makes their own coping resources accessible again and – where necessary – arranges further help. This working definition draws on the understanding developed by Sonneck et al. (2016) in their standard work, but is this course’s own summary. It sets crisis intervention apart in three directions: from everyday counselling, which works without acute pressure to act, from emergency medicine, which averts physical danger to life, and from psychotherapy, which works over a longer period on mental disorders and patterns.

Crisis intervention is therefore not ‘mini-therapy’ and does not replace treatment. It is a bridge: from a state of overload to a state in which the person can again decide for themselves which help they need and accept. This bridging function makes it a natural fit for social work, whose core competence is in any case to assess living situations, open up resources and connect people with suitable help.

Why social work is called upon

Professionals in counselling centres, residential groups, emergency shelters, workshops or hospital social services are often the first to notice a crisis – often long before doctors or therapists are involved. The National Suicide Prevention Strategy of the Federal Ministry of Health (Bundesministerium für Gesundheit, BMG) therefore stresses that, in particular, members of professions who come into contact with people in suicidal crises should be made even more aware and trained in dealing with people at risk (Bundesministerium für Gesundheit [BMG], 2024). Skills in crisis work are thus not a specialism for a few experts but part of the basic professional repertoire. This course can contribute knowledge and occasions for reflection; it neither replaces induction into the procedures of your organisation nor confers any special authority.

PART 2 – Professional foundations: five basic principles

A didactic synthesis, not a canon

The professional literature contains different lists of principles of crisis intervention. The following five basic principles are a didactic synthesis for this course: they bring together ideas found in the standard literature (Sonneck et al., 2016) and in the National Suicide Prevention Strategy (BMG, 2024), but in this form they come from no single source. They are intended as a framework for orientation, not as a checklist. The mind map shows how principles, structure for action, role, network and limits fit together.

Principle 1: prompt, low-threshold help

Crises have their own timeline. The balance has just been lost, the usual ways of coping are not holding, and at the same time openness to support is often particularly great. Help that only becomes available after weeks often comes too late – either the crisis has by then ‘resolved’ itself without support, sometimes at the price of withdrawal, substance use or broken relationships, or it has escalated. Low-threshold means that barriers are deliberately lowered: no application before the first conversation, appointments at short notice, contact by phone or outreach, plain language and a setting that does not increase shame. The National Suicide Prevention Strategy expressly counts telephone and online counselling and crisis services among the building blocks of psychosocial support (BMG, 2024).

Principle 2: relationship as the foundation

Without reliable contact, any further intervention is ineffective. People in crisis often experience themselves as powerless, alone and misunderstood. A calm, attentive counterpart who listens, takes feelings seriously and does not judge is therefore already an intervention. In this context, relationship does not mean closeness at any price but dependable presence: the professional stays available, explains what they are doing and keeps agreements. This strengthens trust that help is possible – an experience that is often lost in a crisis.

Principle 3: focusing on the current trigger

Crisis intervention works in the here and now. Guiding questions are: What has happened? Why now? What is most urgent at the moment? Life history, earlier strains or fundamental conflicts can be significant, but are brought in only as far as they help to understand the current situation. Focusing guards against two typical mistakes: trying to solve ‘everything’ in one conversation, and overloading the person with too many topics at once. A clear focus also provides structure – and structure is a relief when everything inside is in disarray.

Principle 4: activating resources and surroundings

A crisis narrows the view. Those affected often see only the problem and no longer the abilities, relationships and experiences that helped them before. Crisis intervention therefore asks specifically: What has helped you in difficult times before? Who could be there for you now? Involving relatives, friends or trusted people is in principle done with the person’s consent. Activating resources is not sugar-coating but an expression of a human-rights- and resource-oriented stance that takes those affected seriously as active subjects and does not reduce them to their crisis.

Principle 5: safety takes priority

The fifth principle runs through all the others: where life or health is at risk – through suicidality, violence or an acute medical situation – safety takes priority over all other goals. This concerns the person affected, other people such as children in the household, and the professional themselves. In acute danger to life, the emergency number 112 is to be called (Land Niedersachsen, 2025). How suicidality is recognised, raised and evaluated is explored in Modules 4 and 5; the legal questions around confidentiality and involuntary admission are covered in Module 6.

ℹ️Good to know
The principles do not stand side by side but depend on one another: without a relationship no focus can be found, without a focus resources do not become visible, and without an evaluation of safety any planning remains incomplete. If you keep only one question in mind in an acute situation, make it this one: ‘What does this person need now to get safely through the next few hours – and who can help with that?’ The question brings safety, focus and surroundings together in one sentence.

PART 3 – Putting it into practice: the BELLA mnemonic as a structure for action

Five steps that stay available under pressure

Sonneck et al. (2016) structure crisis intervention with the German mnemonic BELLA. It stands for: Beziehung aufbauen (building the relationship), Erfassen der Situation (assessing the situation), Linderung von Symptomen (relieving symptoms), Leute einbeziehen (involving people) and Ansatz zur Problembewältigung (finding an approach to coping with the problem). The value of the mnemonic lies in its simplicity. In an acute situation in which professionals too are under stress, a manageable structure helps to forget nothing essential and later to explain one’s own approach in a traceable way.

STEP 1
B – Building the relationship
Make contact, convey calm, listen, take feelings seriously.
STEP 2
E – Assessing the situation
Clarify the trigger, the strain, any danger and the resources available.
STEP 3
L – Relieving symptoms
Relieve, calm, secure basic needs, involve medical help if needed.
STEP 4
L – Involving people
With consent, activate people close to the person and specialist services.
STEP 5
A – Approach to coping with the problem
Agree small, concrete next steps and secure follow-up.

The steps in detail

Building the relationship deliberately comes first. This includes introducing yourself, creating as calm a place as possible, signalling that you have time and, to begin with, simply acknowledging the person’s experience. Assessing the situation means taking stock together: What is the trigger? How is the person doing physically and emotionally? Are there signs of danger, such as thoughts of not wanting to live any more? Which people and which sources of help are already there? Assessing is not diagnosis – social workers do not make diagnoses – but a structured understanding of the situation as a basis for the next decisions.

Relieving symptoms aims at immediate relief: being allowed to speak, naming feelings, seeing to sleep, food, warmth or a safe place to sleep. Where physical or severe emotional complaints are in the foreground, this also includes bringing in medical help – drug treatment is expressly not a task of social work. Involving people means activating the social network and the professional support system, always with regard to the person’s consent. Approach to coping with the problem finally looks forward: Which first, realistic steps are possible in the next hours and days? Who takes on what? When is the next contact?

It is important to note that BELLA is not a strictly linear scheme. In practice, conversations jump back and forth between the steps, and building the relationship runs alongside the whole process. The order nevertheless offers helpful orientation: anyone who starts with proposed solutions before contact and understanding have been established often meets resistance. The following table summarises aims, typical actions and common pitfalls.

Case example

Mrs Aydın in the hospital social service. Two weeks ago Mrs Aydın gave birth to her first child far too early. The baby is in intensive care, and she shuttles between home and hospital and hardly sleeps. The ward nursing staff ask the hospital social service for support because Mrs Aydın has broken down in tears in the parents’ room and says she ‘can’t cope with it all any more’. The social worker, Ms Neumann, sits down with her, introduces herself, offers water and at first simply listens (B). In conversation she clarifies what makes the situation so unbearable right now: fear for the child, exhaustion, a partner who has to go back to work and the worry of failing as a mother. Gently, she also asks whether Mrs Aydın sometimes has thoughts of not wanting to live any more; Mrs Aydın credibly says no, but says she can no longer think clearly (E). Ms Neumann arranges a short conversation about the exhaustion with the ward doctor and organises a place to rest in the hospital (L). With Mrs Aydın’s consent she phones her sister, who can support her over the next few days (L). At the end the two agree on two small steps: sleeping through one night today, and an appointment tomorrow to discuss together what support is possible for the time after the baby is discharged (A).

Putting it in context: The example shows how BELLA brings order to the situation without turning it into a scheme. The social worker makes no diagnosis and gives no treatment but relieves, clarifies any danger, involves medical expertise and mobilises the person’s surroundings. Had Mrs Aydın said yes to suicidal thoughts, the safety principle would have moved to the front – with immediate involvement of the medical side and the approach described in Modules 4 and 5.

PART 4 – Practice: clarity of role and the chain of care

What social work contributes in a crisis – and what it does not

Clarity of role is an underrated principle of crisis intervention. Those who know their own role act more safely, overload themselves less and can involve other professions more specifically. Social work brings to the crisis its view of the whole living situation: housing, income, work, family, residence status, access to support. It can stabilise, structure, refer on and create continuity. Psychotherapy and psychiatry have different mandates and powers. The following comparison cards illustrate the differences in simplified form.

Social work
  • First contact, offer of a relationship, relief
  • Assessing the living situation and resources
  • Practical help: housing, money, daily life
  • Referral and support into further help
  • No diagnoses, no therapy
Psychotherapy
  • Diagnosis and treatment of mental disorders
  • Working over a longer period on patterns and conflicts
  • Methods requiring their own training and authorisation
  • Often not immediately available in an acute crisis
Psychiatry
  • Medical diagnosis and treatment
  • Drug therapy, inpatient admission
  • Medical evaluation of acute danger
  • Involvement in involuntary admission procedures under state law or custodianship law

Clarity of role does not mean drawing boundaries in the sense of ‘that’s not my job’. On the contrary: precisely because social work does not provide therapy, it can actively support the transition into therapy or treatment – for example by phoning together, accompanying the person to the first appointment or bridging waiting times with supportive contacts. Crisis intervention therefore does not replace therapy, but it often creates the very precondition for people to seek it out.

Crisis help as part of a chain of care

No organisation can cope with crises alone. Effective crisis help arises in a chain in which different services interlock: counselling centres and social work organisations, telephone and online counselling such as the telephone counselling service (TelefonSeelsorge) (TelefonSeelsorge Deutschland, n.d.), doctors in private practice and psychiatric hospitals, the ambulance service and police and – in some states – specialised psychosocial crisis services. The National Suicide Prevention Strategy describes this interplay in several fields of action: health literacy and empowerment, with awareness-raising, early recognition of the need for help and onward referral; psychosocial counselling and support, with crisis services and handover into support services; and networking and coordination (BMG, 2024).

What the chain looks like locally varies greatly by region. Bavaria provides an example of a statutory basis: under Art. 1 of the Bavarian Act on Help for People with Mental Illness (BayPsychKHG), the districts (Bezirke) establish and run crisis services consisting of control centres and mobile professionals; the control centres can be reached around the clock on a single uniform number. This provision applies only to Bavaria and cannot be transferred to other states. There is so far no nationwide uniform crisis service number; the National Suicide Prevention Strategy recommends developing a concept for a central, round-the-clock crisis service emergency number with forwarding to the state crisis services (BMG, 2024).

⚖️Legal framework
Art. 1 BayPsychKHG (example: Bavaria): The districts establish and run crisis services consisting of control centres and mobile professionals; the control centres can be reached around the clock on a single uniform number. Other states regulate crisis services differently or not by law – find out about the services in your region.
Suicide prevention act – not in force: For an ‘Act to strengthen national suicide prevention’, only a ministerial draft exists in the 21st legislative term. Among other things it provides for a time-limited federal specialist office for suicide prevention, a concept for a central, free-of-charge, nationwide uniform number for people in crisis, a digital directory of support services and an advisory board (BMG, 2026). That is not applicable law.
Acute danger to life: Emergency number 112 for the ambulance service and fire service (Land Niedersachsen, 2025).
Legal position: September 2026. This module gives an overview and does not replace legal advice in an individual case; the procedures and agreements of your organisation are also decisive.

Early recognition and onward referral as core tasks

For social work this results in a twofold task. First, early recognition: crises often announce themselves through changes – withdrawal, cancelled appointments, declining self-care, striking remarks, increasing substance use. Those who regularly support clients often notice such changes first and can raise them before the situation escalates. Second, onward referral: it works better when it is active and personal. A phone number on a slip of paper is rarely enough in a crisis; it is more helpful to phone together, to agree an appointment concretely and to fix your own next contact. This requires up-to-date knowledge of the local support landscape – ideally gathered in an overview kept by the organisation and updated regularly.

Case example

Mr Lehmann in integration assistance. Mr Lehmann is in his early twenties and lives in supported housing with outpatient support. For three years he worked in a sheltered workshop for people with disabilities (WfbM); there he had regular tasks, colleagues and a settled daily routine. After several conflicts his place there was ended. Since then he hardly leaves the flat, cancels appointments and told his key worker, Mr Okafor, on the phone that he is ‘no use for anything any more’. His mother, with whom he gets on well, does not yet know anything about all this. Mr Okafor is unsure how serious the situation is and where to start.

Putting it in context: This is a crisis of change: a central area of life that offered structure, recognition and contacts has fallen away, and his usual ways of coping are not enough. His remark that he is ‘no use for anything any more’ is a reason to ask gently and directly about thoughts of harming himself. At the same time, resources are visible: the relationship with his key worker, his mother, earlier work experience. The example is well suited to structuring a plan of action according to BELLA.

✎️ Exercise: structuring a plan of action according to BELLA

Put yourself in Mr Okafor’s position. For each of the five BELLA steps, note two or three concrete actions that you would plan for the next few days. Also consider: at what point would the safety principle change the plan? Whom in the team would you inform, and when?

Show solution notes

B – Building the relationship: offer a home visit soon rather than waiting for the next regular appointment; acknowledge that losing his place at work hurts; talk about the conflicts without blame.

E – Assessing the situation: clarify how Mr Lehmann spends his days, whether he is sleeping and eating, and what is weighing on him most; ask calmly and directly whether he has thoughts of not wanting to live any more; ask about people who matter to him.

L – Relieving symptoms: sketch a daily structure together for the next few days, secure basic care, and – if there is marked low mood or sleeplessness – suggest and support an appointment with his family doctor.

L – Involving people: with his consent, inform his mother; consult the team and the manager; if appropriate, establish contact with a crisis service or a psychiatric outpatient clinic in the region.

A – Approach to coping with the problem: agree small steps, such as a walk together or a conversation about career prospects; firmly arrange the next contact.

Safety: If Mr Lehmann says yes to suicidal thoughts, evaluating the risk and involving medical help come first; in acute danger to life, the emergency number 112 is called. Decisions are not made alone but in the team and according to the procedures of the organisation.

PART 5 – Critical perspective: limits, tensions, open questions

Limits of crisis intervention

Crisis intervention is effective, but it has limits. It cannot remove structural causes of crises – poverty, housing shortage, discrimination, lack of participation – but at most ease their consequences and open paths to further help. It is time-limited and must not permanently take the place of treatment or long-term support. And it reaches its limits where the situation exceeds the competence and powers of social work: in acute medical danger, in questions of involuntary admission or in violence that requires police action. Recognising these limits is itself a professional skill.

Tensions in practice

The clearest tension lies between autonomy and protection. Crisis intervention relies on voluntariness, consent and the person’s self-determination. At the same time, the safety principle requires acting in acute danger even against the person’s wishes at that moment – for example by calling in medical help or the ambulance service. This balancing is legally and ethically demanding and never belongs in the hands of a single professional alone; Module 6 shows which legal standards apply. A second tension exists between speed and relationship: acting quickly may be necessary, but must not bypass contact, because otherwise willingness to accept help falls. A third concerns the individual case and structure: someone working in a region without an accessible crisis service carries in practice more responsibility than a professional in a well-developed network – a problem that cannot be solved by individual effort.

Open questions

At the level of the care system, too, questions remain open. The National Suicide Prevention Strategy sets out goals and fields of action but is not itself a law (BMG, 2024). The ministerial draft for a suicide prevention act would, among other things, create a federal specialist office and a concept for a phone number, but is not yet in force (BMG, 2026). Whether and in what form a nationwide uniform crisis number will come is therefore open. For practice this means: professionals still need to know the services in their region and must not rely on a central solution. It is also open how skills in crisis work can be reliably built into the everyday life of organisations – through guidelines, case discussions and training – without responsibility being shifted onto individual staff.

Consequences for practice

Several practical consequences can be drawn from the basic principles. Organisations benefit from a written crisis guideline that names responsibilities, contact details and local points of contact. Professionals should know the support landscape in their region and refresh that knowledge regularly. Difficult decisions are made in the team and documented in a traceable way – a topic explored in Module 8. And last but not least: anyone who stands by others in crisis needs relief, exchange and permission to reach their own limits. Crisis intervention is teamwork, even when only one professional is in the room at the decisive moment.

Key messages
  • Crisis intervention is time-limited help focused on the current trigger that stabilises, relieves and hands over to further help – it does not replace therapy.
  • Five basic principles give orientation: prompt, low-threshold help, relationship, focus, activating resources and surroundings, and priority for safety.
  • The BELLA mnemonic according to Sonneck et al. (2016) structures the approach: building the relationship, assessing the situation, relieving symptoms, involving people, finding an approach to coping with the problem.
  • Social work makes no diagnoses and gives no treatment; its strength lies in its view of the living situation, in referral and in continuity.
  • Crisis services are a matter for the federal states and are developed differently from region to region; one example of a statutory basis is Art. 1 BayPsychKHG; there is so far no nationwide uniform crisis service number.
For reflection & revision

Voluntary self-reflection – not evaluated, only for your own understanding:

  1. Which of the five basic principles comes easiest to you in your daily work, and which hardest – and why?
  2. Recall a crisis situation from your practice or your surroundings: which BELLA steps were taken into account, and which were missing?
  3. How would you explain to a client what you can do for them in a crisis – and what you cannot?
  4. Which crisis services exist in your region, and how up to date is your knowledge of them?
  5. In which situations do you feel the tension between self-determination and protection most strongly, and who in the team supports you with it?
