Quantitative Findings for Sleep Intervention Testing with Dr Richard

For the sleep experiment, quantitative data is collected to support the qualitative data. I met up with Ricco on 25th March, he generated all the data from the watches into excel sheets and explained to me on how to analyse them. He also shared that the results are positive and I was really quite relieved to hear. Some quantitative data are not recorded as participants forgot to synchronise on some days and 1 participant partied till late and he/she didn't use the interventions because she fell asleep in an instant, these data could be biased thus these data were excluded from the sample t-test for data analysis.

Using IBM SPSS Statistics, the data was analysed with one-sample t-test and the mean is derived.

Baseline data collection: n=3. Average control data from aggregated nights: 7
Intervention testing: n=3 Average control data from aggregated nights: 11

Baseline data*
Sleep latency
25 minutes
7 minutes
Sleep efficiency
Wake after sleep onset (WASO)
36.4 minutes
27.2 minutes
Sleep quality

Findings show that participants’ sleep latency has improved, the duration of time it takes for a person to fall asleep and transition into the sleep stages (Tomorrow Sleep). This implies that the interventions have set a positive mood to help participants fall asleep faster and more easily. On average, there were improvements from each category however one participant only showed improvement for sleep latency and a further investigation is needed to determine why. Although the findings concur with qualitative findings,  this study has limitations and a broader sleep study with a bigger sample size has to be conducted over a longer period to validate the effectiveness of the multi-sensory experience. This pilot study demonstrates positive findings that is worthwhile to run a further study.

A 2-week follow-up (from their last qualitative interview with me) will be initiated through video interviews with the 3 sleep participants and the focus group.

Data generated by IBM SPSS Sample t-Test can be found here
Participants have kindly allowed me to publish their data, data will solely be used for MA research findings and analysis only.
