Optimal scoring of the Multidimensional Pain Inventory in a chronic pain sample.
The Multidimensional Pain Inventory (MPI) is one of the most commonly used self-report instruments in pain settings. The MPI can be used to classify patients into three clusters or its nine scales can be treated as dimensions in efforts to understand patient heterogeneity. ⋯ Results suggest that dimensional models consistently outperform cluster models in explaining variance in outcome variables, and that the addition of a measure of defensiveness increments the validity offered by the MPI scales. Implications for the assessment of pain patients are discussed.

Randomized Controlled TrialFrequent assessment of negative symptoms does not induce depressed mood.
Use of real-time data collection is rapidly expanding in the medical sciences and questions have been raised as to whether frequent ratings of disease symptoms could evoke depressed mood. This study investigated the effect of an intensive momentary assessment protocol on depressed mood. Community rheumatology patients (N = 105) were recruited to participate in a 30-day momentary assessment protocol of pain and fatigue. ⋯ Depression scores were significantly lower following the protocol (p < .001). Whereas 10% of patients shifted into a more depressed category at the end of the protocol, 20% shifted into a less depressed category. These findings suggest frequent assessment of pain and fatigue may not induce depressed mood, and may in some instances be associated with a small reduction in depressed mood.
