abstract = {Background:Functional connectivity has garnered interest as
a potential biomarker of psychiatric disorders including
borderline personality disorder (BPD). However, small sample
sizes and lack of within-study replications have led to
divergent findings with no clear spatial foci.Aims:Evaluate
discriminative performance and generalizability of
functional connectivity markers for BPD.Method:Whole-brain
fMRI resting state functional connectivity in matched
subsamples of 116 BPD and 72 control individuals defined by
three grouping strategies. We predicted BPD status using
classifiers with repeated cross-validation based on
multiscale functional connectivity within and between
regions of interest (ROIs) covering the whole brain—global
ROI-based network, seed-based ROI-connectivity, functional
consistency, and voxel-to-voxel connectivity—and evaluated
the generalizability of the classification in the left-out
portion of non-matched data.Results:Full-brain connectivity
allowed classification (∼70 $\%)$ of BPD patients vs.
controls in matched inner cross-validation. The
classification remained significant when applied to
unmatched out-of-sample data (∼61–70 $\%).$ Highest
seed-based accuracies were in a similar range to global
accuracies (∼70–75 $\%),$ but spatially more specific.
The most discriminative seed regions included midline,
temporal and somatomotor regions. Univariate connectivity
values were not predictive of BPD after multiple comparison
corrections, but weak local effects coincided with the most
discriminative seed-ROIs. Highest accuracies were achieved
with a full clinical interview while self-report results
remained at chance level.Limitations:The accuracies vary
considerably between random sub-samples of the population,
global signal and covariates limiting the practical
applicability.Conclusions:Spatially distributed functional
connectivity patterns are moderately predictive of BPD
despite heterogeneity of the patient population.},
