Using early change to predict outcome in cognitive behaviour therapy: exploring timeframe, calculation method, and differences of disorder-specific versus general measures.

Early change can predict outcome of psychological treatment, especially in cognitive behavior therapy. However, the optimal operationalization of "early change" for maximizing its predictive ability, and differences in predictive ability of disorder-specific versus general mental health me...
