Abstract
We studied self-observations related to weight management
recorded with a Wellness Diary application on a mobile
phone. The data were recorded by 27 participants in a
12-week study, which included a short weight management
lecture followed by independent usage of the Wellness
Diary. We studied the validity of self-observed weight,
and behavioural changes and weight patterns related to
weight management success. Self-observed weight data
tended to underestimate pre- and post-study measurements,
but there were high correlations between the measures (r
? 0.80). The amount of physical activity correlated
significantly with weight loss (r = 0.44) as did
different measures representing healthy changes in
dietary behaviours (r ? 0.45). Weight changes and the
weekly rhythms of weight indicated a strong tendency to
compensate for high-risk periods among successful
weight-losers compared to unsuccessful ones. These
preliminary results suggest that the mobile phone diary
is a valid tool for observing weight management and
related behaviours
