Review Meta Analysis
Cognitive remediation in schizophrenia: A methodological appraisal of systematic reviews and meta-analyses.
Systematic reviews and meta-analyses are a primary source of evidence when evaluating the benefit(s) of cognitive remediation (CR) in schizophrenia. These studies are designed to rigorously synthesize scientific literature; however, cannot be assumed to be of high methodological quality. The aims of this report were to: 1) review the use of systematic reviews and meta-analyses regarding CR in schizophrenia; 2) conduct a systematic methodological appraisal of published reports examining the benefits of this intervention on core outcome domains; and 3) compare the correspondence between methodological and reporting quality. ⋯ Reviews concerning CR for schizophrenia are a valuable source of evidence. However, the methodological quality of these reports may require additional consideration. Enhancing quality of conduct is essential for enabling research literature to be interpreted with confidence.

Randomized Controlled Trial
Affective regulation in trichotillomania before and after self-help interventions.
Trichotillomania (TTM) is characterized by recurrent hair-pulling behaviours that cause significant distress. Deficits in affective regulation have been reported in individuals with TTM. We aimed to investigate temporal stability of affective regulation in TTM individuals. ⋯ Individuals with TTM reported deficits in affective regulation that demonstrated mostly high relative stability and partly absolute stability. Therefore, targeting to improve affective regulation in individuals with TTM during therapy is warranted.
