Operationalization
Participants were randomly assigned to:
1. POSITIVE PSYCHOLOGY INTERVENTION
Participants first completed an adapted version of the Person-Activity Fit Diagnostic
online. The PAFD asks respondents to rate 10
different activities (eg, acts of kindness, socializing, physical activity, meditation) on 5 dimensions. The 4 activities that received the
highest ratings were identified as those that best matched the participants’ interests. The 4 exercises selected for each participant were then sent by email each on 1 to maximal 2 pages attached as a portable document format and imbedded in the email text. Participants were instructed to perform at least one of the exercises for at least 15 minutes, at least 1 day every week (including on bad days with higher than average levels of pain)  for 8 weeks.

0: CONTROL GROUP.
Participants were instructed to be more attentive to their surroundings and write about 3 specific events or activities from the past 7
days for at least 15 minutes once a week for 8 weeks.
