Comparing the percentage of non-overlapping data approach and the hierarchical linear modeling approach for synthesizing single-case studies in autism research / Mieke HEYVAERT in Research in Autism Spectrum Disorders, 11 (March 2015)

Titre : Comparing the percentage of non-overlapping data approach and the hierarchical linear modeling approach for synthesizing single-case studies in autism research Type de document : Texte imprimé et/ou numérique Auteurs : Mieke HEYVAERT, Auteur ; Lore SAENEN, Auteur ; Bea MAES, Auteur ; Patrick ONGHENA, Auteur Article en page(s) : p.112-125 Langues : Anglais (eng) Mots-clés : Single-case research Single-subject experimental designs Meta-analysis Systematic review Behavioral interventions Challenging behavior Index. décimale : PER Périodiques Résumé : We examined the performance of two approaches for synthesizing single-case experimental data: the percentage of non-overlapping data (PND) approach and the hierarchical linear modeling (HLM) approach. The comparison was performed by analyzing an empirical dataset on behavioral interventions for reducing challenging behavior in persons with autism by means of the two approaches. We compared the findings of both approaches for analyzing the outcomes of the behavioral interventions as well as for identifying moderating variables. With respect to the analysis of the interventions’ outcomes, similar positive results were found based on both approaches. With respect to the moderating variables, Functional analysis/assessment and Availability of follow up data were found to be statistically significant moderators by means of the PND as well as the HLM approach. The variables Intervention type, Availability of generalization attempts, Design type, and Availability of inter-rater reliability data were also found to be statistically significant moderators by means of the PND approach. The PND approach seems overly liberal in identifying statistically significant predictors in comparison to the HLM approach.

Titre : Intensive prolonged exposure treatment for adolescent complex posttraumatic stress disorder: a single-trial design Type de document : Texte imprimé et/ou numérique Auteurs : Lotte HENDRIKS, Auteur ; Rianne A. DE KLEINE, Auteur ; Mieke HEYVAERT, Auteur ; Eni S. BECKER, Auteur ; Gert-Jan HENDRIKS, Auteur ; Agnes VAN MINNEN, Auteur Article en page(s) : p.1229-1238 Langues : Anglais (eng) Mots-clés : Complex PTSD treatment outcome adolescents prolonged exposure intensive treatment Index. décimale : PER Périodiques Résumé : Background The current study evaluated the effectiveness and safety of intensive prolonged exposure (PE) targeting adolescent patients with complex posttraumatic stress disorder (PTSD) and comorbid disorders following multiple interpersonal trauma. Methods Ten adolescents meeting full diagnostic criteria for PTSD were recruited from a specialized outpatient mental health clinic and offered a standardized intensive PE. The intensive PE consisted of three daily 90-min exposure sessions delivered on five consecutive weekdays, followed by 3 weekly 90-min booster sessions. In a single-trial design, the participants were randomly allocated to one of five baseline lengths (4–8 weeks) before starting the intensive PE. Before, during, and after intensive PE completion, self-reported PTSD symptom severity was assessed weekly as a primary outcome (a total of 21 measurements). Furthermore, clinician-administered PTSD diagnostic status and symptom severity (primary outcome), as well as self-reported comorbid symptoms (secondary outcomes), were assessed at four single time points (baseline-to-6-month follow-up). Results Time-series analyses showed that self-reported PTSD symptom severity significantly declined following treatment (p = .002). Pre-postgroup analyses demonstrated significant reductions of clinician-administered PTSD symptom severity and self-reported comorbidity that persisted during the 3- and 6-month follow-ups (all ps < .05), where 80% of adolescents had reached diagnostic remission of PTSD. There was neither treatment dropout nor any adverse events. Conclusions The results of this first proof of concept trial suggest that intensive PE can be effective and safe in an adolescent population with complex PTSD, although the gains achieved need to be confirmed in a randomized controlled trial.
