Outcome Measures

Primary Outcomes (1)

  • Questionnaire using the experience sampling method, administered by the mobile phone application.

    The mobile phone application questionnaire will be offered 10 times a day at random moments on the smartphone of the participants, during a 3 months period. The mobile phone application questionnaire contains a series of multiple choice questions about the present affect (three positive, five negative), the present context and activities (physical activity, occupation, presence of other people), physical discomfort (fatigue, concentration level, pain) and mobile phone usage (frequency, frustration when unable to use phone) since the last beep. Positive affect: cheerful, mentally fit and relaxed. Negative affect: irritated, bored, lonely, stressed and worrying. The answers will be registered using a 7-point scale, ranging from 'not' to 'very'.
