Problems in measuring the success of family therapy in a common clinical setting: impasse and solutions

Families treated in conjoint therapy in the outpatient clinic of a general community hospital for about a year and other families that refused further contact with the same clinic after no more than two interviews were followed up about four and a half years later. The main difference found was that the treated group reported more new symptoms. The complexities of interpreting the data obtained are used as a basis for discussing problems that confront, and may deter, clinics attempting to evaluate their clinical work by means of controlled, nonfactorial or related designs. Process or correlational studies are suggested as an alternate choice.
