Use of a novel electronic data collection system in multicenter studies of irritable bowel syndrome.

BACKGROUND: The reliability of symptom data collected during efficacy studies in irritable bowel syndrome (IBS) is paramount to the proper assessment of potential therapeutic agents. Historically, data have been collected on paper diary cards, which patients were requested to fill out at a specified interval. However, with paper diary cards it is not possible to determine whether the cards are filled out as required, or at random times. To circumvent this problem, a novel electronic data collection system that ensures the reliability and security of data entry was used. METHODS: Data were collected from 640 patients during the 2-week screening and 12-week treatment phases of two multicentre trials of IBS. The electronic data collection system used was based upon a touchtone telephone system. RESULTS: The electronic data collection system had a potential 8135 up-time hours during the study. An up-time of 8040 h and down-time of 95 h was observed. This corresponds to an up-time of approximately 99%. Patient compliance for data entry in the two studies was 81% and 83%, respectively. On a single random day during their daily telephone call, patients were asked questions to assess satisfaction with the system. On aggregate, 79% of patients were satisfied or very satisfied with the system, only 10% were dissatisfied or very dissatisfied. CONCLUSION: A unique electronic data collection system was tested for use in clinical studies in IBS. This system provided 100% reliability as to the date of data entry, and data were not subject to modification once entered. This methodology represents a marked advancement in clinical studies of IBS.

The effects of distraction on desensitization and reprocessing.

The present analogue study of seventy-two students with mild spider anxiety assessed the role of distraction in the desensitization and reprocessing of aversive information. Accessing different components of Baddeley's model of short-term memory, three treatment groups involving distraction tasks and one control group maintaining focussed exposure were compared in a pre-test post-test experimental design. The results indicated that all groups experienced a similar reduction in both self-report and heart-rate measures of anxiety. However, at the follow up phase, the groups containing a distraction task showed an increase in anxiety levels significantly greater than that for the control condition. No differences were reported between any of the distraction groups.
