In brief
If a child or adolescent with autism often reacts in an oppositional or aggressive way, the 2021 S3 guideline recommended first clarifying the causes. This includes a precise behavioural analysis (when, where, with whom, how often and how it is responded to) and clarifying possible physical or mental conditions that may lie behind it. [1, Rec. 61] Where necessary, the environment should be adapted and over-demand avoided; as first-choice treatment, the guideline named psychosocial services, including parent training. [1, Rec. 61] The guideline expired on 23.03.2026. [2]

Status of the guideline: This article uses the S3 guideline on therapy (2021). It expired on 23.03.2026. [2] The statements are not automatically wrong, but they are not backed by a valid guideline.
Understand first: behavioural analysis and causes
For this area, the guideline adopted recommendations from British source guidelines. [1, Rec. 61] According to them, the primary causes of oppositional and aggressive behaviour should be addressed with suitable measures. With a differentiated behavioural analysis, information should be collected from those affected themselves, from parents and other carers (for example teachers) and from direct observation. The question is when, where, with whom, in what form and how often the behaviour occurs and how it is responded to. This makes it possible to identify possible causes and maintaining factors. [1, Rec. 61] In addition, accompanying mental or physical conditions that may be related should be recognised, diagnosed and treated according to the state of the evidence. [1, Rec. 61] More on this: Common co-occurring conditions in autism and Sleep problems in autism.
Adjustments in everyday life
If the behavioural analysis shows indications of a connection, according to the guideline changes to the environment should be made, for example visual support in structuring demands or sleep hygiene. Over-demand should be recognised, and demands should be adapted to the level of development (cognitive, emotional and language skills). [1, Rec. 61] More examples of structure in everyday life: Routines and structure in everyday life.
Parent training
If there are no physical or mental conditions or environmental factors that trigger or maintain the behaviour, psychosocial services based on the behavioural analysis should be offered as primary treatment when the intensity of the behaviour is moderate. Particular attention should be paid to building competences and to effective positive reinforcement of functional behaviour. [1, Rec. 61]
For preschool, primary school and adolescent age, the guideline recommended (grade of recommendation A) manualised, behaviour-therapy-based parent training. It should support the parents’ parenting skills, strengthen their sense of efficacy and thereby indirectly reduce the behaviours of children and adolescents. In role plays, among others the following skills should be worked out and practised: positive parent–child interaction, communication and the child’s emotion regulation, effectively setting and enforcing rules and clearly refraining from punitive behaviour (for example scolding). Practical exercises with homework come in addition. [1, Rec. 61] The training is not directed against you: it is meant to support you and your child. The guideline gave evidence level 2 to 3 for this recommendation; how such information is to be read: How good is a study?. [1, Rec. 61]
Further options
- If caregivers are under high strain, drug treatment should additionally be given; doctors decide on this. [1, Rec. 61] More: Medication in autism.
- In addition to parent training, interventions from the S3 guideline on conduct disorder can be considered; for self-injurious behaviour, the recommendations of an AWMF guideline on non-suicidal self-injurious behaviour can apply after an individual behavioural analysis. [1, Rec. 62]
