Be consistent in your form. Where this isn't possible, let the reader know which information is not available, or why you elaborated on one event and not the other. Report information clearly and with confidence. Once you've made it clear that the history came from clinical interview, you don't need to repeatedly qualify the data. One way to avoid this is to use quotation marks occasionally to let the reader know you are relating the patient's opinions.
Qualifiers are important at times, but excessive use reveals indecision or uncertainty.
The patient may have conflicts dealing with authority figures. Include only details that are relevant to your conclusions. Excess details distract the reader from the case you are building in support of your conclusions. For chronic schizophrenia you might spend several paragraphs on past treatment efforts and only a sentence or two on family issues. For an avoidant personality disorder, you might spend several paragraphs on family and other interpersonal issues, while devoting only a couple of sentences to prior treatment.
