“…This measure gives an indication of the internal consistency of the scale. Generally values larger that .70 are considered to be acceptable, although lower thresholds are sometimes considered to be tolerable if the scale contains few items (Carlo, Eisenberg & Knight, 1992;Cortina, 1993;Nunnally, 1978;Santos, 1999). Sensation Seeking was questioned using Arnett's Inventory of Sensation Seeking (AISS) (Arnett, 1994).…”

“…25 The internal consistency (ie Cronbach's a) of the RNBI Scales ranged from 0.67 to 0.90 and testretest reliability coefficients ranged from 0.63 to 0.96 and were acceptable as recommended by Nunnally and Bernstein. 26 Validity of the RNBI was also acceptable. The postmorbid emotional scales of the RNBI were significantly correlated (P ¼ 0.01) with matching subscales of the Millon Clinical Multiaxial Inventory-III.…”

Impact of spinal cord injury on self-perceived pre- and postmorbid cognitive, emotional and physical functioning

Study Design: Cross-sectional study with repeated measurements. Objectives: To examine the patient's perspective of the impact of spinal cord injury (SCI) on physical, cognitive, emotional function, and quality of life (QOL). Setting: Australia. Methods: A sample of 63 patients with SCI, 32 of whom had recent injuries, and 31 with established injuries were administered the Ruff Neurobehavioral Inventory to examine patients' subjective evaluation of pre-and post-injury functioning. Current happiness levels were also evaluated using the Subjective Happiness Scale. A follow up assessment was performed 6 months later to examine changes over time. Results: A significant difference was found between perception of pre-and postmorbid function on composite Cognitive (t ¼ 5.99, df ¼ 62, Po0.001), Physical (t ¼ 11.56, df ¼ 62, Po0.001), and QOL (t ¼ 7.16, df ¼ 62, Po0.001) scales and on several of the Emotional subscales including anxiety, paranoia and suspicion, and substance abuse (Po0.001). A series of hierarchical regression analyses indicate that post-SCI pain was a significant predictor of: cognitive (R 2 ¼ 0.20, Po0.001); emotional (R 2 ¼ 0.13, Po0.004); and of QOL (R 2 ¼ 0.22, Po0.001) functioning. With the exception of a decrease in happiness (Po0.01), there were no significant changes in any measures over the 6 month time period. Conclusions: There are significant changes in patients' perceptions of physical and cognitive functioning, and of QOL before and after SCI and some aspects of emotional functioning. Pain has a significant adverse effect on functioning. Happiness decreased slightly in the 6 months between surveys.

This study comprised the first step in the psychometric development of a self-report screening instrument for risk of opioid medication misuse among chronic pain patients. A 26-item instrument, the Pain Medication Questionnaire (PMQ), was constructed based on suspected behavioral correlates of opioid medication misuse, which heretofore have received limited empirical investigation. The PMQ was administered to 184 patients at an interdisciplinary pain treatment center. Reliability coefficients for the PMQ were found to be of moderate but acceptable strength. Construct and concurrent validity were examined through correlation of PMQ scores to measures of substance abuse, physical and psychological functioning, and physicians' risk assessments. To explore high and low cutoff points for misuse risk, subgroups were formed according to the upper and lower thirds of PMQ scores and compared on validity measures. Higher PMQ scores were associated with history of substance abuse, higher levels of psychosocial distress, and poorer functioning. Future psychometric analyses will consider predictive validity and examine shortened versions of the instrument.
