A Comprehensive Approach to Trauma, Substance Use, and Behavioural Interventions

Introduction
Domestic violence (DV) and coercive control are pervasive issues that affect individuals across all genders, leading to complex diagnoses such as Post Traumatic Stress Disorder (PTSD) and reliance on substances such as alcohol and/or other drugs. There is also a high correlation between these experiences and those people who have high scores on the Adverse Childhood Experiences (ACE) scale, indicating a history of significant trauma. Understanding the behaviours associated with these experiences and implementing effective support strategies is crucial for empowering individuals in their recovery journey. This comprehensive article explores the behavioural manifestations of trauma, the role of the Questions About Behavioural Function (QABF) in understanding these behaviours, and the strategic support needed to address the challenges of substance reliance and other related issues.
The Complexity of Diagnoses in Trauma-Exposed Individuals
Individuals with a history of DV and trauma often present with complex diagnoses, including PTSD and substance reliance. These conditions are interrelated, with trauma frequently serving as a precursor to substance use as a coping mechanism. The cycle of abuse in DV relationships—characterised by tension-building, incidents of violence, reconciliation, and calm—can lead to long-lasting psychological effects, including PTSD, anxiety, depression, and learned helplessness.
Anecdotal Example: Consider Alev, a participant who experienced severe emotional and physical abuse in a past relationship. To cope with the trauma, Alev turned to alcohol, which temporarily numbed the emotional pain but also led to dependency. This cycle of trauma and substance use has resulted in cognitive impairments and social isolation, making it difficult for her to engage in daily activities or seek support.
Behavioural Manifestations and the Role of QABF
The QABF is a valuable tool for identifying the primary functions behind specific behaviours, which can be particularly useful in understanding the behaviours of individuals with complex diagnoses. By categorising behaviours into attention, escape, tangible, sensory, and nonsocial functions, the QABF provides insights into the motivations behind behaviours, guiding the development of effective interventions.
Attention: Some individuals may exhibit behaviours that seek validation or reassurance from others, reflecting a need for connection and validation. These behaviours can be a response to past neglect or emotional abuse.
Escape: Avoidance of social situations or responsibilities may function as an escape from anxiety or distress associated with past trauma. For instance, avoiding crowded places might be a way to prevent anxiety attacks linked to PTSD.
Tangible: Substance use may function as a tangible behaviour where the individual seeks the effects of drugs or alcohol to cope with emotional pain or stress, providing temporary relief or control.
Sensory: Engaging in repetitive or self-soothing actions, such as pacing or rocking, provides calming sensory feedback and helps manage anxiety or distress.
Nonsocial: Withdrawal or isolation can be a way for individuals to process their emotions internally, serving as a coping mechanism for dealing with overwhelming feelings.
Anecdotal Example: Jamie, a participant who has left an abusive relationship, struggles with social interactions due to hyper-vigilance and anxiety. Jamie's behaviour support practitioner uses the QABF to identify that these behaviours serve as escape and sensory functions, helping Jamie avoid distressing emotions and providing temporary relief.
Empowerment Through Support
Empowerment is a key component in supporting individuals with complex diagnoses. By focusing on their strengths and fostering resilience, practitioners can help them regain control over their lives.
Trauma-Informed Care: Creating a safe and supportive environment is foundational. Practitioners should approach each participant with empathy and understanding, acknowledging the impact of their trauma on current behaviours.
Positive Behaviour Support (PBS): Implementing PBS strategies can help reinforce desirable behaviours and teach new skills. For example, Alex might benefit from learning healthier coping mechanisms, such as mindfulness or creative expression, to replace substance use.
Skill-Building and Independence: Encouraging individuals to develop new skills can enhance their sense of autonomy and self-efficacy. This might include vocational training, education, or workshops on emotional regulation.
Anecdotal Example: After engaging in a series of art therapy sessions, Jamie, a participant with a history of DV, discovers a passion for painting, which not only serves as an emotional outlet but also opens up new social and professional opportunities.
Support Networks: Facilitating connections with supportive communities can reduce isolation and provide ongoing encouragement. Peer support groups, for instance, offer a space for shared experiences and mutual empowerment.
Addressing the Challenges of Substance Reliance
Reliance on substances such as alcohol and/or other drugs is a significant challenge for individuals exposed to trauma, such as DV and coercive control. Understanding the impact of substance reliance on these individuals is crucial for developing effective support strategies that address both the addiction and the underlying trauma.
Cognitive and Physical Impairments
Substance reliance can lead to cognitive impairments, such as memory loss, difficulty concentrating, and impaired decision-making. These cognitive deficits can hinder individuals' ability to engage in daily activities and make informed choices about their health and well-being.
Physically, substance reliance can result in liver damage, cardiovascular issues, and increased risk of falls, particularly in individuals with pre-existing conditions such as brain atrophy. These physical health issues can further compound the challenges faced by trauma-exposed individuals.
Emotional and Behavioural Challenges
Substances may be used as a means to numb emotional pain or avoid confronting traumatic memories. However, they can also lead to heightened emotional volatility, increased risk of engaging in risky behaviours, and exacerbation of mental health conditions such as anxiety and depression.
Social Isolation and Dependency
Individuals with substance reliance often experience social isolation, as their focus on obtaining and consuming substances can lead to withdrawal from social interactions and support networks. This isolation can perpetuate feelings of loneliness and dependency, making it difficult for individuals to seek help and engage in recovery.
Barriers to Treatment
Several barriers can impede treatment for individuals with complex needs, particularly those with a history of DV and substance reliance:
Hypervigilance and Lack of Trust: Trauma can lead to hypervigilance and a deep-seated lack of trust in others, especially authority figures. This can make it challenging for individuals to engage with support services or disclose their experiences.
Uncertainty and Fear of Change: The uncertainty associated with leaving an abusive relationship or changing substance use habits can be overwhelming. Fear of the unknown may prevent individuals from seeking help or committing to treatment.
Indoctrination to the Abuser's Beliefs: Long-term exposure to coercive control can result in indoctrination to the abuser's beliefs and values, leading to self-blame and a diminished sense of self-worth. This can hinder individuals' ability to recognise their strengths and pursue recovery.
Stigma and Shame: The stigma associated with DV and substance use can lead to feelings of shame and guilt, further isolating individuals and discouraging them from seeking support.
Support Strategies for Overcoming Barriers
Developing effective support strategies for individuals with substance reliance and trauma histories requires a comprehensive approach that addresses these barriers:
Harm Reduction Approaches
Harm reduction strategies focus on minimising the negative impacts of substance use while respecting individuals' autonomy and readiness to change. This might include safe consumption practices, gradual reduction plans, and providing access to clean and safe environments.
Integrated Health and Social Services
A multidisciplinary approach that includes addiction specialists, mental health professionals, and healthcare providers can address both the physical and psychological aspects of substance reliance. This collaborative approach ensures that individuals receive comprehensive support that addresses their holistic needs.
Trauma-Informed Care
Providing trauma-informed care that acknowledges the impact of past experiences on current behaviours is crucial. This involves creating a safe and supportive environment where individuals feel respected and understood, and tailoring interventions to be sensitive to their trauma history.
Empowerment and Engagement
Encouraging individuals to engage in activities that empower them and provide a sense of purpose can help reduce reliance on substances. This might include vocational training, creative expression, or advocacy work. By fostering a sense of autonomy and self-efficacy, individuals are more likely to engage in recovery and pursue meaningful goals.
Case Studies and Examples
Case Study 1: Mark's Journey to Recovery
Mark, a 45-year-old man, had a history of DV and developed reliance on alcohol as a coping mechanism. His behaviour support practitioner implemented a harm reduction approach, focusing on safe drinking practices and gradual reduction plans. By collaborating with a multidisciplinary team, Mark received comprehensive support that addressed both his addiction and trauma.
Over time, Mark engaged in vocational training and developed new skills that provided a sense of purpose and autonomy. This empowerment significantly improved his quality of life and reduced his reliance on alcohol.
Case Study 2: Anna's Path to Empowerment
Anna, a 30-year-old woman, had experienced severe emotional and physical abuse and developed reliance on substances as a way to cope with her trauma. Her practitioner provided trauma-informed care, creating a safe and supportive environment where Anna felt respected and understood.
Anna participated in a peer support group, where she connected with others who had similar experiences. This sense of community provided emotional support and encouraged her to pursue further education. Anna's journey highlights the importance of empowerment and collaborative care in fostering long-term recovery.
Conclusion
Supporting individuals with complex needs, particularly those who have experienced DV and coercive control, requires a comprehensive and empathetic approach. By understanding the behavioural functions of their challenges through tools like the QABF and focusing on empowerment, practitioners can help these individuals navigate their recovery journey, fostering resilience and opening pathways to a brighter future. Through trauma-informed care, positive behaviour support, harm reduction strategies, and integrated services, we can empower these individuals to reclaim their lives and thrive beyond their past experiences.
