Trial Outcomes & Findings for Pilot Clinical Trial of Computer-based Motivational Intervention - 1 (NCT NCT00230022)

NCT ID: NCT00230022

Last Updated: 2013-06-20

Results Overview

An eight-item measure tapping motivation to change, self-efficacy, and change intention was assessed using visual analog scales. The average of the eight items was calculated resulting in a score ranging from 1 to 100. The measure was asked at baseline (reported in baseline data) and the one month follow-up. Scores here represent average level of motivation for change at the time of follow-up. Higher scores represent higher levels of motivation to change, self-efficacy and intention to change.

PRIMARY outcome

Timeframe: One month

Population: A total of 30 participants were included in this pilot trial, based primarily on convenience and timeframe. The primary goal was effect-size estimation, so power was not a primary concern. Last Observation Carried Forward(LOCF) was utilized for 8 participants lost to follow-up.

An eight-item measure tapping motivation to change, self-efficacy, and change intention was assessed using visual analog scales. The average of the eight items was calculated resulting in a score ranging from 1 to 100. The measure was asked at baseline (reported in baseline data) and the one month follow-up. Scores here represent average level of motivation for change at the time of follow-up. Higher scores represent higher levels of motivation to change, self-efficacy and intention to change.
