Outcome measures
Primary outcome
The primary study parameters are the duration of the weightlifting task.
Secondary outcome
Secundairy parameters are catastrophising about pain, fear of movement and
(re)injury, negative and positive affectivity, experienced pain during the
weighlifting task, subjective experienced duration of the weightlifting task,
subjective threat value of the weightlifting task. These variables are measured
because they can influence task persistence (the dependent variable) as well.
Experienced positive and negative mood will be assesed as a manipulation
check.
Background summary
Until recently, the Fear Avoidance Model was the most important model that gave
an explanation for chronic pain. But this model can not explain everything; in
particular it has problems to explain why some people with chronic pain persist
in an activity despite their pain. Furthermore, the model does not give any
information about the role that positive mood plays in task persistence.
A new promissing model that can help to explain these issues is the mood as
input model. This model proposes that a combination of mood and goal (also
called 'stop rule') determines how long one persists in an open-ended activity.
In general two kinds of goals are distinghuised: a performance goal (enough
stop rule) and a enjoyment goal (enjoy stop rule). According to the mood as
input model, people use their mood to interpret the progress they are making in
reaching their goal.
So if someone has a performance goal and is in a negative mood, this will be
interpreted as a sign that the goal is not reached yet and that the task has to
be continued. According to this line of reasoning, a person with a performance
goal will stop sooner with an activity when he is in positive mood, compared to
when he is in a negative mood. The opposite patern is expected when an
enjoyment goal is adopted: one will stop sooner when in a negative mood than
when in a postive mood, because the negative mood serves as a signal that one
is no longer enjoying the task and the task has to be terminated.
On the basis of this model an interaction between mood and goal is expected.
Until now, the model has only been tested with healthy participants, using a
cognitive persistence task
Study objective
The aim of the study is to test, for the first time, whether physical task
persistence in people with chronic pain can be explained by the mood as input
model.
Study design
The study is a quasi-experiment. It uses a 2 Mood (positive vs negative)
between subject design. The independent variables are mood and stop rule. Stop
rule is not experimentally manipulated, but it is measured with the habitual
stop rule questionnaire.
The dependent measure is the time that people persist with the weightlifting
task.
Intervention
A mood manipulation (positive versus negative) will be done by means of movie
fragments.
Study burden and risks
The total burden for the participants is minimal: the time investment is
minimal (maximum 1 hour) and there are no risks in carrying out the tasks.
Watching the negative mood induction film fragment can cause a temporary more
negative mood state.
Carrying out the weightlifiting task can cause some discomfort, in that it can
cause some (worsening of) painful sensations.
Previous research that has used the weightlifting task with chronic pain
patients, shows that the task is not harmful.
Furthermore, it is important to notice that the duration of the weightlifting
task is the independent variable and that participants can decide for
themselves when they want to stop with the task. In any case, the maximum
duration of the task (5 minutes) will not be exceeded.
