The Impact of E-diaries and Accelerometers on Young Adults' Perceived and Objectively Assessed Physical Activity.

ABSTRACT:

Objective

E-diaries and accelerometers promise more objective, real-time measurements of health behavior. However, social-psychological theory suggests that using electronic behavioral monitoring may influence rather than just record physical activity (PA), especially when a device is novel.

Design

Participants (n=146) were randomly assigned to either an accelerometer-only, e-diary-only, accelerometer+e-diary, or a no-technology control group for one week to assess how these technologies influenced PA, both perceived and actual, in young adults.

Method

Participants reported their PA, overall and number of discrete exercise sessions (DES) at baseline and follow-up; accelerometers provided daily step counts and e-diaries captured daily reports of PA for the active week
