Internet-based exposure treatment versus one-session exposure treatment of snake phobia: a randomized controlled trial
Abstract
In this study, the authors compared guided Internet-delivered self-help with one-session exposure treatment (OST) in a sample of snake phobic patients. A total of 30 patients were included following a screening on the Internet and a structured clinical interview. The Internet treatment consisted of four weekly text modules which were presented on a web page, a video in which exposure was modelled, and support provided via Internet. The OST was delivered in a three-hour session following a brief orientation session. The main outcome was the behavioural approach test (BAT), and as secondary measures questionnaires measuring anxiety symptoms and depression were used. Results showed that the groups did not differ at post-treatment or follow-up, with the exception of a significant interaction for the BAT in favour of the OST. At post-treatment, 61.5% of the Internet group and 84.6% of the OST group achieved a clinically significant improvement on the BAT. At follow-up, the corresponding figures were 90% for the Internet group and 100% for the OST group (completer sample). Within-group effect sizes for the Snake Phobia Questionnaire were large (d = 1.63 and d = 2.31 for the Internet and OST groups, respectively, at post-treatment). It is concluded that guided Internet-delivered exposure treatment is a potential treatment option in the treatment of snake phobia, but that OST probably is better.

Two Randomized Controlled Trials in Sweden for animal phobia compared in vivo exposure to a self-help ICBT with text modules and videos with guidelines to carry out exposure therapy in daily lives.
“Regarding studies focused only on specific phobias, two Randomized Controlled Trials (RCT) were conducted in Sweden for animal phobia (Andersson et al., 2009, Andersson et al., 2013). In them, in vivo exposure was compared to a self-help ICBT with text modules and videos with guidelines to carry out the exposure therapy in their daily lives.”

“When it comes to specific phobias, Andersson et al. 40 and Andersson et al. 41 had opposing results: individuals with spider phobia responded better to iCBT (g = 0.3249, 95% CI: - 0.4296 to 1.0795), while those with snake phobia favored face-to-face CBT (g = - 0.5503, 95% CI: - 1.3123 to 0.2117).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
