“…41 Missing Data. We contacted the authors of three studies [43][44][45] that met inclusion criteria but did not report adequate outcome data to be included in the meta-analysis. While two provided the needed data, for the third (Agras et al) 45 we imputed pre-and post-intervention standard deviations by generating a conservative estimate based upon pre-and poststandard deviations of the other study populations included in this review.…”

“…23 However, the findings of this meta-analysis suggest that the use of computers themselves adds little to the success of many weight loss interventions. The advent of numerous portable electronic devices (e.g., smart phones) and new applications, such as social networking sites, might add additional capabilities or effects, but we only found two qualifying studies 43,45 that included such devices. This is not surprising given the time required to conduct and publish studies that include newer devices.…”

The Effect of Computers for Weight Loss: A Systematic Review and Meta-analysis of Randomized Trials

BACKGROUND:The use of computers to deliver education and support strategies has been shown to be effective in a variety of conditions. We conducted a systematic review and meta-analysis to evaluate the impact of computer-based technology on interventions for reducing weight. METHODS: We searched MEDLINE, CENTRAL, CINAHL, PsycINFO, Google Scholar and ClinicalTrials.gov (all updated through June 2010) for randomized controlled trials evaluating the effect of computer-based technology on education or support interventions aimed at reducing weight in overweight or obese adults. We calculated weighted mean differences (WMD) and 95% confidence intervals (CI) using random effects models. RESULTS: Eleven trials with 13 comparisons met inclusion criteria. Based on six comparisons, subjects who received a computer-based intervention as an addition to the standard intervention given to both groups lost significantly more weight (WMD −1.48 kg, 95% CI −2.52, -0.43). Conversely, based on six comparisons, subjects for whom computer-based technology was substituted to deliver an identical or highly comparable intervention to that of the control group lost significantly less weight (WMD 1.47 kg, 95% CI 0.13, 2.81). Significantly different weight loss seen in "addition" comparisons with less than six months of follow-up (WMD −1.95 kg, 95% CI −3.50, -0.40, two comparisons) was not seen in comparisons with longer follow-up (−1.08 kg, 95% CI −2.50, 0.34, four comparisons). Analyses based on quality and publication date did not substantially differ. CONCLUSIONS: While the addition of computer-based technology to weight loss interventions led to statistically greater weight loss, the magnitude (<1.5 kg) was small and unsustained.

“…These efforts should further increase acceptability of computers in therapy. Second, many researchers have strongly advised that computer programs be used in conjunction with therapy administered by a human to ensure ethical and effective procedures (e.g., Agras, Taylor, Feldman, Losch, & Burnett, 1990). However, some evidence suggests that improvements can been achieved by use of computer programs alone (e.g., Selmi, Klein, Greist, Sorrell, & Erdman, 1990).…”

The identification of dysfunctional thoughts is a central effort in cognitive therapy. This paper describes the first version of a computer module that classifies dysfunctional thoughts automatically. It is part of COGNO, a system we are developing to give automatic feedback on dysfunctional thoughts. The system uses rules that were developed from language markers identified in a sample of 149 dysfunctional thoughts. The system was tested with an independent set of 112 example thoughts. The system detects the majority of dysfunctional thoughts, but works reliably only for some thought categories. Automatic thought classification may be a first step toward developing natural dialogue systems in cognitive therapy.

“…11, 231-242 (2003) Copyright # Over a decade ago, researchers began to use palmtops for psychosocial treatment. For example, the use of a palmtop program (with only one introductory face-to-face session) was as effective for weight loss as was a therapist-conducted weight loss programme (Agras, Taylor, Feldhan, Losch, & Burnett, 1990). More recently, palmtops have been tested and utilized in conjunction with cognitive behavioural treatment for anxiety disorders.…”

Palmtop computers may provide an innovative and effective extension of psychotherapeutic treatment for eating disorders. Palmtop applications have been used historically in studies utilizing ecological momentary assessment methodology, and in this capacity their portability and immediacy have been advantageous. In this paper, a new treatment for bulimia nervosa will be described which includes palmtop modules as therapy extension devices. The format of the therapy will be reviewed along with the specific content of the modules. Advantages of such microcomputer applications will be discussed, as well as methodological challenges.
