In client-centred therapy , more sessions were used for diagnostic consultation ( @ % points difference , p = @ ) ; the time needed to formulate the first treatment goal was longer ( @ days difference , p = @ ) ; there was a tendency towards more goals directed to diagnostic issues ( @ goals difference , p = @ ) , spending more hours on indirect issues ( @ h difference , p = @ ) and towards a longer total therapy period ( @ months difference , p = @ ) than in usual care .
