Medical treatment is usually accompanied by a warning about potential side effects. While constituting an important part of informed consent, these warnings may themselves contribute to side effects via the placebo effect. I investigated this possibility among a sample of university students experiencing sleep difficulty. Under the guise of a trial of a new hypnotic, participants were allocated to receive a placebo treatment (lactose capsules) or no treatment for one week. In addition, participants were allocated to receive a warning about side effects (either increase or decrease in appetite, counterbalanced) or no warning. Placebo treatment led to significantly better sleep on almost all self-reported outcomes. Furthermore, placebo treated participants who received a warning about side effects were significantly more likely to report those side effects.
After honours I completed an ABA (Applied Behavioural Analysis) training and worked with children with autism in Sydney. This included in-home therapy as well as shadowing at pre-school. I then moved to Berlin, Germany and am worked as a social worker in an apartment for young adults with autism. I am currently completing a masters in clinical psychology at UTS
