Auricular Acupuncture for Chronic Pain and Insomnia

Insomnia Severity Index (ISI). Assesses the perceived severity and impact of insomnia symptoms based on a 5-point Likert with a total score from 0-28 with >14 indicating moderate to severe insomnia. The sensitivity and specificity are 94% using a cutoff score of 14. Good test-retest (.78), face validity as defined by DSM-IV, and concurrent validity (.32 - .99)

Sleep Diary 69. Collects and quantifies daily, subjective bedtime and waketime sleep parameters 70. A sleep diary in various formats is often used as a diagnostic tool for sleep disorders. In addition, due to one major weakness of validity check of real time completion, the sleep diary is often used in conjunction with actigraphy to establish validity in sleep parameters. Based on the recommendations for standard research assessment, a sleep diary should assess the following information: sleep onset latency (SOL), final waketime, number of awakenings (NWAK), wake after sleep onset (WASO), total sleep time (TST), sleep efficiency (SE), sleep quality (SQ), and time/duration of naps. Sleep diaries are standard practice and recommended for use in research studies of sleep disorder treatments.

Actigraphy is a watch-like device that documents sleep/wake patterns via movement over a period of time to estimate sleep parameters. It records in-time blocks (epochs) the participant's movement, light exposure, and other measures using accelerometry and a light meter. Various clinical research studies that have compared the outcomes among actigraphy vs. polysomnography (PSG) - the gold standard in sleep research. Correlation rates have been >90% in healthy adults and >84% in patients with sleep related breathing disorders when actigraphy has been compared to PSG 73,74. For Actiwatch 2, scoring software of Actiware will be used to determine sleep parameters of SOL, NWAK, WASO, TST, and SE.

. Assesses four pain items and the degree of interference with seven aspects of functioning using a 0-10 Numeric Rating Scale. Four pain items include "pain now," "pain at its worst," "pain at its least," and "average" over the last 24 hours. The BPI also includes the location of pain on a body chart and the use of pain medications. "Worst pain" or the arithmetic mean of the 4 severity items can be used as measures of pain severity and the arithmetic mean of the 7 interference items can be used a as a measure of pain interference. Validity and reliability are high in various chronic pain populations (.77-.91)

This 5-item scale was developed by a 22-member Pain Management Task Force as a standard pain assessment in the Department of Defense (DoD)/Veterans Administration (VA) system for continuity of care of service members. However, there are very few studies on its validity and reliability. The scale integrates a currently used numeric pain rating scale with visual facial cues and word descriptors. In addition there are 4 supplemental questions on pain interference modified from the BPI. Construct validity using component factor analysis revealed one item group (factor loadings >.78 and >.81) for outpatient and inpatient participants, respectively, with high internal consistency (.87-.90)
