I think that trust is built between what the therapist does and what the patient does. I don't think there's a formula, and I think it is different for different people.

As far as what the therapist does, imo, when I disclose information, I find it very important that he/she NOT use it against me to hurt me. That would be a breach of trust.

I think a therapist needs to be true to his word, if he makes promises, then he should keep them. To not do so would be breach of trust and damaging to the patient.

me but me. When a therapist presumes to know what I need, it can easily slip into the countertransferential area.

I have read in a book before, where a therapist stated that in no way would he just go with what they patient told him they needed. He included information from previous therapists, from family, etc. I am the only one who knows who I am. Period.
