NCT ID: NCT01293695

Last Updated: 2016-08-16

Results Overview

The Hot Flash Symptoms Diary was used to measure hot flash frequency. Participants recorded their hot flashes over seven days by daily frequency and severity. This instrument provides a measure of hot flash frequency and hot flash score (product of frequency x severity).

Timeframe: 6 Weeks and 12 Weeks

Hot Flash Score is a product of frequency of hot flashes × severity of hot flashes, which could range from 0 (best possible outcome) to infinity (worst possible outcome). Hot flash frequency and hot flash severity were obtained using the Hot Flash Symptoms Diary. Participants recorded their daily hot flashes marking each hot flash (frequency) and rating the severity of each as mild (1), moderate (2), severe (3), and very severe (4). The values presented represent the average of daily hot flash scores.

This questionnaire is used to measure the effects of hot flashes on women as they go about their daily activities. Answers on the scale can range 0 (Do Not Interfere) to 10 (Completely Interfere). The total score was computed by averaging the subjective ratings over the 10 items. A lower score indicates better outcome.

SECONDARY outcome

Timeframe: 6 Weeks and 12 Weeks

Population: Analysis was conducted on all available physiological data to determine hot flash frequency. Data was missing for 29 participants in the hypnosis group and 17 participants in the structured attention group.

As a secondary outcome, hot flashes were measured using a Biolog ambulatory recorder. Skin conductance was expressed in micro Siemens (0 to infinity) and the final value was obtained by averaging the recorded skin conductance for a period of 24 hours. Lower skin conductance measure indicates less sweating.

SECONDARY outcome

Timeframe: 6 Weeks and 12 Weeks

The Pittsburg Sleep Quality Index (PSQI) is a self-report inventory designed to measure sleep quality. The participants self rate their sleep quality over seven areas of sleep.The questions about sleep quality are answered on a 0-3 scale with higher scores indicating greater sleep pathology. The global score is determined by summing the raw scores of the seven sleep components. The global score can range from 0 - 21 and total scores above 5 are normally considered indicative of poor sleep quality.
