This dissertation explores the long-term impacts of parental alcohol dependence on adult psychological wellbeing, attachment patterns and intergenerational behaviours. Although extensive research has examined the immediate effects of parental substance misuse on children, less attention has been given to how these experiences shape adult outcomes within a UK context. To address this gap, a qualitative literature-based methodology was adopted, drawing on ten UK-focused peer-reviewed studies and national reports. Thematic analysis identified three interconnected themes: psychological wellbeing, attachment patterns and intergenerational behaviours.
The findings demonstrate that parental alcohol dependence is associated with enduring emotional consequences, including anxiety, hypervigilance and difficulties with emotional regulation. These outcomes align with trauma theory and the wider Adverse Childhood Experiences (ACEs) literature. The second theme highlights the prevalence of insecure attachment patterns, with adults frequently reporting mistrust, relational avoidance and fear of abandonment. The third theme reveals how early relational disruption can influence adult coping strategies and parenting practices, although many individuals also demonstrate resilience and intentionality in breaking intergenerational cycles of harm.
The implications for social work practice emphasise the need for trauma-informed, relational and attachment-focused approaches, alongside improved early intervention, multi-agency collaboration and life-course-oriented support. The dissertation concludes that parental alcohol dependence has significant and enduring impacts across emotional, relational and behavioural domains, underscoring the importance of holistic, strengths-based and non-stigmatising social work responses. Recommendations for practice, policy and future research are provided to support more effective identification, intervention
