These questionnaires include traditional question sets, while others take a different approach. For instance, the speech questionnaire requires users to record themselves reading a specific text or answering a question, rather than responding to written prompts.
The passive application runs in the background, requiring minimal or no input from participants. Data are collected from smartphone “sensors” and from integrated wearable devices.

Evaluating a Remote Monitoring Program for Respiratory Diseases: Prospective Observational Study
Second, a multidimensional questionnaire and speech and vocalization sampling were administered using the RADAR-base active mobile phone app. Third, data were collected from a number of devices: continuous passive monitoring using the Garmin vivoactive 4 and active monitoring outcomes using a daily finger pulse oximeter. Daily lung function measurements were collected using a Nuvo Air spirometer in the COPD and ILD cohorts (Table 1).

Small to moderate correlations between PHQ-8 scores and the features were found in cross-sectional studies where participants were monitored for a relatively short time period with a limited number of PHQ-8 measures per participant [11,12]. Discrepancies in findings could be due to study design, population, sample size, and data [14].
A number of challenges exist for these studies.

The smartphone-based active data were collected through (1) clinical questionnaires, (2) a series of speech tasks delivered directly to the participant’s phone via a custom-built app (the RADAR active RMT app), and (3) validated cognitive assessments in gamified format requiring a separate app, the THINC-it app [28]
Cognitive tasks were completed monthly, whereas the speech task, which required the participants to record themselves reading a short text [29] and answering a question aloud, was delivered fortnightly

If a swing phase ends and a stance phase starts, we can identify a step that occurred. The formal detection rule of a step Si at sample i is that the following two conditions must be satisfied: (1) a change from –0.5 to 0 in B1 (B1i=0 and B1i–1=0.5); (2) there is at least one detection of B2=–0.5 in a window of size w=150 milliseconds in sample i (Min(B2i:i+w)=–0.5).
Then, the gait cycle series could be derived by calculating time intervals between consecutive steps, which was denoted as Cycles.

Depression is a prevalent and serious mental health disorder that is a leading cause of disability worldwide [1]. It can cause physical health and psychological function problems, resulting in loss of productivity and a high social burden [2-5]. Currently, diagnosis of depression relies on skilled clinicians and self-report questionnaires, which have limitations that include subjective bias and dynamic information loss [6].

Ideally, a GPS signal sampled uniformly over a period of 5 minutes would give 12 GPS data points per hour and a total of 288 GPS data points per day. We specified completeness of the daily data as a ratio between the actual number of GPS data points collected over a day and the expected number as determined by a sampling period (ie, 288 and 144 GPS data points for the sampling periods of 5 minutes and 10 minutes, respectively).

On completion of the data collection period, we will measure the total available data as a function of a theoretical maximum and assess data quality measured by a range of criteria, including missingness and contiguity.
The potential of remote monitoring will be evaluated in the context of cardiopulmonary disorders.
