Research on this App

A Randomized Controlled Trial of 88 college students explored the initial efficacy and sustained effects of using Calm for 8 weeks compared to a wait-list control on stress, mindfulness, and self-compassion in college students with elevated stress. Those who used Calm differed significantly on the outcomes of stress, mindfulness, and self-compassion (Huberty, Green, Glissmann, Larkey, Puzia, & Lee. 2019. https://mhealth.jmir.org/2019/6/e14273)

A cross-sectional survey of 12,151 paid subscribers of the Calm app aimed to describe the demographics, clinical characteristics, and usage patterns of the sample and explore the relationship between self-reported app usage and changes in health, stress, and sleep. The frequency of using Calm was associated with incremental changes in noticing changes in mental health, physical health and stress (Huberty, Vranceanu, Carney, Breus, Gordon, & Puzia. 2019. https://mhealth.jmir.org/2019/11/e15648/)

In a qualitative study of Calm with myeloproliferative neoplasm (MPN) patients, 29%(14/48) of the patients only used the 10% Happier app, 21% (10/48) of the patients only used the Calm app, and 46% (22/48) of the patients used both apps during the 8-week intervention. The qualitative findings of this study suggest that MPN patients who are naïve or nearly naïve meditators perceived mobile phone meditation as enjoyable, preferred the Calm app over the 10% Happier app, perceived the Calm app as more appealing (eg, narrator’s voice and different meditations or background sounds offered), and perceived beneficial effects of meditation on mental health, sleep, fatigue, and pain. (Huberty, Eckert, Larkey, Joeman, & Mesa. 2019. https://cancer.jmir.org/2019/2/e14292)

In another study, adult cancer patients and survivors who are Calm users (N=82) were recruited through the Daily Calm Facebook page. Participants completed a Web-based survey related to Calm app use and satisfaction, interest in and ideas for a cancer-specific Calm app, and demographic characteristics. Responses suggest ways in which the current Calm app could be adapted to better fit cancer patients’ and survivors’ needs and preferences, including adding cancer-specific content, increasing the amount of content focusing on coping with strong emotions, developing communities for Calm users who are cancer patients and survivors, and including features that track cancer-related symptoms (Huberty, Puzia, Eckert, & Larkey. 2020. https://cancer.jmir.org/2020/1/e16926/?utm_source=TrendMD&utm_medium=cpc&utm_campaign=JMIR_TrendMD_1) “
