Primary Outcome Measures:
- Laughter Frequency [ Time Frame: 14 days ]
Documenting each instance of laughter throughout each day.
- Pain Ratings [ Time Frame: Three times per day for 14 days ]
Rating overall pain from 0 to 10, three times daily
- Emotional State [ Time Frame: Three times per day for 14 days ]
Rating momentary emotional state three times per day
Behavioral: Laughter Frequency
Relationships between laughter frequency, momentary mood state, and pain will be observed.
Participants will be asked to provide (or authorize the researcher to obtain) fibromyalgia diagnosis confirmation from a health care provider.
Initially, participants will complete a demographics form and two screening assessments. Then for 14 days, they will be asked to rate their momentary mood and overall pain levels three times per day (shortly after waking up, around 3:00 p.m., and at about an hour before bedtime). At the same time, they will be asked to log each instance of laughter as it occurs, daily, for 14 days. They will carry the log with them throughout each day in order to document each instance of laughter.
