SANZ, Jesús  and  GARCIA-VERA, María Paz. Techniques for the analysis of single-case designs in clinical practice: examples of application in the treatment of victims of terrorist attacks. Clínica y Salud [online]. 2015, vol.26, n.3, pp.167-180. ISSN 2174-0550.

This paper presents two techniques for the data analysis of single case designs in psychological treatment research: indices of data overlap between phases to estimate the size of treatment effect (or the magnitude of therapeutic change) and Jacobson and Truax's (1991) statistical approach to estimate the clinical significance of treatment effect. Based on a case of a victim of terrorism who suffered from posttraumatic stress disorder, major depressive disorder and panic disorder with agoraphobia and received trauma-focused cognitive-behavioral therapy, this paper illustrates the computation and application of percentage of non-overlapping data (PND), percentage of data points exceeding the median (PEM), non-overlap of all pairs (NAP), and statistical approach to clinical significance, and discusses their advantages and limitations as a complement of visual analysis of data.

Keywords : Single-case design; Treatment effectiveness evaluation; Data analysis; Effect size; Clinical significance.
