1. Theory of Operant Conditioning

• Operant conditioning involves learning through consequences, where behaviours leading to desirable outcomes are reinforced, while those leading to undesirable outcomes are discouraged.
• Skinner's principles of operant conditioning emphasize the role of consequences in shaping behaviour, known as the Law of Effect.

2. Background

• Poor adherence to prescribed asthma medication regimes is common among pediatric patients.
• behaviour therapy, based on principles of classical and operant conditioning, has been used to improve adherence.
• The study aimed to evaluate a novel asthma spacer device, the "Funhaler," designed to improve adherence through positive reinforcement.

3. Research Method

• Field experiment conducted in participants' home settings in Australia, using a repeated measures design.
• IVs: Use of standard/small volume spacer device vs. Funhaler.
• DV: Adherence to prescribed medical regime.

4. Sample

• 32 children (22 male, 10 female) aged 1.5 - 6 years, with asthma, were recruited.
• Parents provided informed consent and participated in the study.

5. Procedure

• Comparison made between aerosol output of standard/small volume spacer device and Funhaler, ensuring no significant differences.
• Participants used each device sequentially for two weeks, with adherence measured through self-report and parental observation.
• Questionnaires and interviews assessed ease of use, compliance, and treatment attitudes.
• The Funhaler incorporated features to distract children and reinforce effective technique.

6. Key Findings

• Funhaler use associated with improved parental and child compliance.
• 81% of children using Funhaler were medicated the previous day compared to 59% using the standard spacer.
• More children achieved recommended aerosol delivery cycles with the Funhaler.
• Parents reported greater success in medicating children with the Funhaler compared to the standard spacer.
• Fewer problems reported with the Funhaler.

7. Possible Conclusions

• The Funhaler shows promise in improving adherence and delivery characteristics in young asthmatics.
• Functional incentive devices like the Funhaler may have positive effects on children's health.
• Further research is recommended to assess long-term efficacy and clinical outcomes.
