Clinical prediction models are widely used in modern clinical practice. Such models are often developed using individual patient data (IPD) from a single study, but often there are IPD available from multiple studies. This allows using meta-analytical methods for developing prediction models, increasing power and precision. Different studies,…

Innovations in data science like predictive analytics, data mining, and data reduction have improved a variety of fields. Innovations in data science have also enabled the growth of two data-driven movements primarily used in clinical and counseling psychology: the common factors and common elements approaches. Each of these movements contains…

Therefore, the authors conducted a needs-assessment survey to determine the needs of IMGs transitioning into psychiatry residency.…

Most psychotherapy research uses a one-with-many design, in which each therapist (the one) treats multiple clients (the many), which raises the challenge of nonindependent data. We present a statistical model for analyzing data from studies that use a one-with-many design. This model addresses the problems associated with nonindependence and can…

Researchers examining the therapy relationship are encouraged "to study both patients' and therapists' contribution to the relationship and the ways in which these contributions combine to impact treatment outcome" (Steering Committee, 2002, p. 443). Research on the therapeutic alliance, however, is dominated by studies that examine the individual…
