Link between APD and Substance Abuse

1. Early alcohol use and substance abuse loosen behavioural inhibitions and therefore contribute to APD

2. APD may make individuals vulnerable to substance abuse

3. APD and substance abuse may have the same cause, such as a deep-seated need to take risks

The Psychodynamic Approach

  • Proposes people who substance abuse have strong dependancy needs that can be traced back to childhood
  • Those that become fixated in the oral stage are needy and overly dependant on people and material objects
  • The child will grow to become highly reliant on other people and material objects
  • if others fail to provide reasurrance, nuture and comfort, drugs become a substitute resulting in addiction

Evaluation

  • No empirical evidence
  • Only looks at childhood as a cause
  • Generalises from case studies
