In our relaunch article, we mentioned that we were excited about the initial results of the program and it's effectiveness, and we'll share some of those details at a later date. Today is that day and we'd like to share some of those results. First we will discuss some background on the program, what measures were used, and how the analysis was preformed.
Currently we offer a free online therapy for depression program, this program teaches user skills and strategies for overcoming depression and is based on Cognitive Behavioural Therapy. Each week there is a new lesson on techniques that can improve people's mental health, but prior to the lesson we measure people's mood using a scientifically developed depression scaled called the CES-D. There is a minimum of 7 days between each measure, since each lesson becomes available one week after completing the previous session.
The data is anonymized and then cleaned up. To measure change in mood at least two pieces of data is required, in addition, the program is concerned with helping those exhibiting depressed mood, so data is further cleaned up by selecting sets that meet this threshold at begining of the program as defined by the depression scale.
To analyze the data a t-test analysis is performed on the initial mood score and the final mood score available. An initial analysis was performed in similar fashion between the first and second mood scores. Both analysis showed improvement in mood scores, more important the changes were statistically significant and had a p-value of < 0.05. The initial test between first and second mood scores had a t-value of 2.32043. The p-value of .024614. The initial and final mood score test had even more significant results with a t-value of 2.81558. The p-value of .007043. The box plot below captures the results of this second test.
These are very preliminary results with limited datasets, and has been only analyzed internally so further analysis using different statistical tests, more data, and outside validation would help further establish these results.
Overall we are very encouraged by these results and looking to continue analyzing the effectiveness of our program. More importantly we are excited that the trend of these results support our mission to help people around the world improve their mental health.
