Background:
The widespread use of smartphones makes effective therapies such as cognitive-behavioural therapy (CBT) potentially accessible to large numbers of people.
Aims:
This paper reports the usage data of the first trial of Catch It, a new CBT smartphone app.
Method:
Uptake and usage rates, fidelity of user responses to CBT principles, and impact on reported negative and positive moods were assessed.
Results:
A relatively modest proportion of people chose to download the app. Once used, the app tended to be used more than once, and 84% of the user-generated content was consistent with the basic concepts of CBT. There were statistically significant reductions in negative mood intensity and increases in positive mood intensity.
Conclusions:
Smartphone apps have potential beneficial effects in mental health through the application of basic CBT principles. More research with randomised controlled trial designs should be conducted.
Declaration Of Interest:
