Anomia Treatment Efficacy Depending on Aphasia Type, Severity, and Therapy Amount - Article Example

Meta-analysis Anomia treatment efficacy depending on aphasia type, severity, and therapy amount In the treatment of anomia, the meta-analysis evaluation was conducted which focused on the efficiency of therapy for anomia because of aphasia. It mainly focused on calculating the effect size of the therapy. The study focused on moderator variables such as type of treatment, follow up measure, word set and time post-onset. The results depicted a substantial distinction in effect size depending upon whether the confrontational naming task involved a trained or untrained word set or not.

The purpose of this meta-analysis extends the previous research by evaluating these anomia studies to focus on the efficacy of treatment depending on moderator variables such as aphasia type, severity, therapy frequency, the total amount of therapy hours and the number of trained items. The effect size was calculated to represent the gains made for all participants confrontational naming tasks as follows: D= (Mpost tx-Mpre tx)/SDpre tx. Further, the unbiased effect of the study was calculated as follows: Unbiased d= (1-(3/ (4*total n)-9))*d.

The pre-and post-measures were categorized within studies to evaluate moderator variables such as type of aphasia, Aphasia severity, number of sessions per week and the total number of therapy hours (excluding the number of sessions).
