Abstract

Background Little is known about which participant characteristics determine the effectiveness of various types of cognitive behavior therapy for sub-threshold depression. The aim of this study was to investigate which characteristics predict treatment outcome of group and internet-based interventions for sub-threshold depression, with a special focus on (i) the five main personality factors, and (ii) their different predictive power in the different types of treatment.Methods Eighty-five women and 45 men (mean age=55 years, S.D.=4.4) were randomly assigned to a group treatment and an internet-based treatment. The outcome measure was the difference between pre-treatment and post-treatment BDI scores. Analyses of Covariance were conducted to examine which participant characteristics could predict outcome for the two different types of treatment.Results Higher baseline BDI scores (F(1,111)=52.88, p<.01), female gender (F(1,111)=6.45, p=.01), and lower neuroticism scores (F(1,111)=7.24, p=.01) predicted better outcome after both treatments. In the group intervention, participants with higher altruism scores improved significantly more after treatment (F(1,111)=3.94, p=.05) compared to the internet-based condition.Limitations Axis-II disorders were not considered; the study assessed personality traits rather than personality disorders.Conclusions Outcomes of different types of cognitive behavior therapy for sub-threshold depression are partly predicted by different participant characteristics. Neuroticism was associated with worse outcomes in both types of treatment, while altruism seems to be exclusively related to more favorable outcomes in the group treatment.

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.
