Reliability and validity of an interactive computer method for rating quality of life

Integrating pain management in clinical practice

There is much evidence to suggest that psychological and social issues are predictive of pain severity, emotional distress, work disability, and response to medical treatments among persons with chronic pain. Psychologists can play an important role in the identification of psychological and social dysfunction and in matching personal characteristics to effective interventions as part of a multidisciplinary approach to pain management, leading to a greater likelihood of treatment success. The assessment of different domains using semi-structured clinical interviews and standardized self-report measures permits identification of somatosensory, emotional, cognitive, behavioral and social issues in order to facilitate treatment planning. In this paper, we briefly describe measures to assess constructs related to pain and intervention strategies for the behavioral treatment of chronic pain and discuss related psychiatric and substance abuse issues. Finally, we offer a future look at the role of integrating pain management in clinical practice in the psychological assessment and treatment for persons with chronic pain.

Electronic pain assessment in clinical practice

SUMMARY The assessment and treatment of chronic pain remains an international challenge for healthcare providers among aging patients and rising healthcare costs. This article provides a brief overview of studies on the use of electronic pain diaries and innovative software programs for pain assessment and monitoring among providers and persons with chronic pain. The advent of software pain monitoring programs on smart phones, personal digital assistants and internet-based tracking allow for the collection of large datasets of momentary data to better assist in the management of chronic pain. Electronic tracking in the home and clinic can improve data quality and reduce the biases of recalled information compared with paper diaries and questionnaires. Furthermore, 3D pain mapping programs can enable patients to represent the location and intensity of their pain with greater accuracy. However, despite the benefits, there are a number of barriers to incorporating electronic pain assessment into daily clinical practice. Additional control trials and clinical investigations are needed to demonstrate the efficacy and benefit of electronic pain assessment over and above standard practices.

A computer method for assessing satisfaction with hearing aids

The purpose of this study was to evaluate a new clinical assessment, the Dynamic Assessment of Hearing Aids (DAHA), for a large clinical population. Unlike traditional questionnaire methods, the DAHA has patients use an intuitive graphical computer interface to record visual analogue ratings of satisfaction with various features of their hearing aids (e.g. clarity, cost, appearance). Data were collected from 191 participants.A subset of participants returned for retest. The DAHA items assess satisfaction with hearing aids within four domains: communication, physical features, sound quality, and personal reactions. The concurrent validity was determined by comparing DAHA results to those obtained with the satisfaction with amplification in daily life (SADL). Ratings for personal reactions to hearing aids indicate the most satisfaction, and ratings for communication (especially group conversations and phone use) indicate the least satisfaction. The DAHA total score was found to have good test/retest and high internal consistency. Concurrent validity was supported by a strong correlation between total scores on the DAHA and the SADL. Results suggest the DAHA maybe an effective tool for clinical use.

Computer Assessment and Diagnostic Classification of Chronic Pain Patients

OBJECTIVE

In order to establish a diagnosis of chronic pain, emphasis is placed on a patient's report of the pain's intensity, location, and character. The aim of this study was to evaluate the feasibility of a computer assessment method to collect self-reports of pain that were then used in discriminant analyses to distinguish among chronic pain diagnoses.

METHODS

A convenience sample of 511 patients from two university-based pain clinics completed a computer pain assessment battery that elicited demographic information, pain drawings, pain and emotion intensity ratings, and intensity ratings of verbal descriptors. Patients classified themselves into one of six chronic pain diagnoses. Discriminant analyses were performed in an attempt to identify the unique features of patients' pain experience associated with each of the diagnostic categories.

RESULTS

Pain drawings successfully classified patients into three of the diagnostic categories (back, head, and neck pain). In a second analysis, two pain descriptors (cramping and stabbing) separated rheumatoid arthritis patients from those with either fibromyalgia or neural pain. One descriptor of pain (cramping) and one descriptor of emotion (frustration) together distinguished between fibromyalgia and neural pain.

CONCLUSIONS

1) Computer assessment of a range of patient symptoms is feasible in the pain clinic. 2) Discriminant analysis based on pain drawings can distinguish among patient-reported diagnoses of back pain, headache, and neck pain. 3) Discriminant analysis based on three verbal descriptors can help to distinguish among diagnoses of fibromyalgia, neuralgia, and rheumatoid arthritis. 4) However, in general, most computerized descriptive information is not useful in distinguishing differences among pain patient diagnostic groups.

Validation of the short-form interactive computerized quality of life scale (ICQOL-SF)

OBJECTIVE

To evaluate the concurrent validity of the short form of an interactive computerized quality of life (ICQOL-SF) measure for patients with chronic pain.

METHODS

The ICQOL-SF, consisting of one global and four separate domains of quality of life, was administered to 300 chronic pain patients in two pain centers. Participants also completed the full 21-item interactive computerized quality of life (ICQOL) program, a computerized version of the World Health Organization Quality of Life Scale (WHOQOL-BREF), and a computerized assessment of pain (CAP) program. In a second study, an independent group of 336 chronic pain patients completed the ICQOL-SF, the WHOQOL-BREF, and the CAP.

RESULTS

The ICQOL-SF in both studies demonstrated adequate concurrent validity with the WHOQOL-BREF (r = 0.75) and the CAP (r = 0.84). The five-item ICQOL-SF was also highly correlated with the full ICQOL (r = 0.90). Surprisingly, older individuals with more formal education and longer pain duration reported better quality of life. Number of past surgeries was negatively correlated with quality of life.

CONCLUSIONS

The five-item short-form interactive computerized method to assess quality of life demonstrates adequate concurrent validity and would be a useful, brief software measure in the assessment of persons with chronic pain. Additional studies are needed to determine the reliability and sensitivity to change of the ICQOL-SF.
