Examination of the validity of the Brief Neurocognitive Assessment (BNA) for schizophrenia

Achievement motivation in early schizophrenia: Relationship with symptoms, cognition and functional outcome

“…Neurocognition was evaluated using the Brief Neurocognitive Assessment for schizophrenia (Fervaha, Agid, Foussias, & Remington, 2014b;Fervaha et al, 2015a). This tool includes measures of processing speed and working memory, and the composite score has shown high overlap with lengthier cognitive assessment batteries in schizophrenia (Fervaha et al, 2014b;Fervaha et al, 2015a).…”

Life satisfaction and happiness among young adults with schizophrenia

“…Clinical insight was evaluated using the Schedule for the Assessment of Insight (SAI) (David, 1990), while global neurocognition was evaluated using the Brief Neurocognitive Assessment (BNA) for schizophrenia (Fervaha et al, 2014a(Fervaha et al, , 2015c. Finally, functional outcome was evaluated using the Quality of Life Scale -Abbreviated version (Fervaha et al, 2014b).…”

“…All clinical variables were examined for entry into this model. Neurocognition scores were transformed to age-and sexmatched Z-scores based on normative data (Fervaha et al, 2015c). Diminished expression was evaluated using the sum of the affective flattening subscale (excluding the global item) and the poverty of speech item from the SANS.…”

Effort-based decision making as an objective paradigm for the assessment of motivational deficits in schizophrenia

“…During the first visit, psychopathology was evaluated using the 18-item Brief Psychiatric Rating Scale (BPRS) (Guy, 1976), and the self-report version of the Apathy Evaluation Scale (AES) (Marin et al, 1991). Neurocognition was evaluated using the Brief Neurocognitive Assessment for Schizophrenia (Fervaha et al, 2014a(Fervaha et al, , 2015.…”

“…Neurocognition scores were transformed to age-and sexmatched Z-scores based on normative data (Fervaha et al, 2015). Discrete aspects of psychopathology such as positive and negative symptom severity was evaluated using factor scores derived from the BPRS (Mueser et al, 1997), while severity of overall symptoms was quantified using the total score from the BPRS.…”
