Behavioural Treatment - McGrath

Aim- To treat a girl with specific noise phobias using systematic desensitisation.

Pps-  Lucy 9yrs with fear of sudden loud noises, lower than av. IQ, wasnt depressed.

  • Procedure- Constructed hierarchy of feared noises
  • taught breathing + imagery to relax - imagine herself at home on bed with her toys
  • had hypothetical fear thermometer for rating fear 1-10
  • given stimulus of loud noise she paired feared object with relaxation and imagery
  • this lead to feelings of calmness so she associated the noise with feeling calm
  • Findings- After 4 sessions she learned to feel calm when noise was presented + didnt need to use imagery
  • 10th and final session fear thermometer scores gone from 7/10 to 3/10 for ballons
  • 9/10 to 3/10 for party poppers
  • 8/10 to 5/10 for cap guns
  • conclusions: important factors - giving lucy control to say when/where noises made
  • using inhibitors of fear response (relaxation and playful environment).

Cognitive Treatment - Beck et al.

  • Aim- Compare effectiveness of cognitive therapy and drug therapy
  • Method- Controlled experiment with pps allocated to 1 of 2 conditions
  • Pps- 44 patients diagnosed with moderate-severe depression attending psychiatric outpatients clinics.
  • Procedure- Pps assessed with 3 self-reports before treatment (Becks Depression Inventory, Hamilton Rating Scale and Rasking Scale)
  • for 12 weeks patients had 1-hour cognitive therapy session twice a week or 100 imipramine capsules prescribed by visiting doctor for 20mins each week
  • cog therapy sessions prescribed and controlled and therapists were observed to ensure reliability
  • Findings- Both groups showed significant decrease in depression symptoms
  • cognitive treatment group showed significantly greater improvements on self-reports and observer-based ratings (78,9% compared to 20% of those with drug therapy)
  • drop-out rate 5% in cognitive therapy and 32% in drug treatment

Conclusion- Cog therapy leads to better treatment of depression, shown by fewer symptoms, and also better adherence to treatment.
