An adult or teen should not be observed without her prior consent. Clinical observation in natural settings often reveals a person's strengths and assets . Families and others in a setting where problem behaviors occur are often so frustrated and exhausted that they lose sight of what the person can do well. The outside observer can more readily note the adaptive behaviors. Taking note of an individual's strengths is a critical factor in his overall success.
Some individuals have mobility challenges, and many families have transportation problems.
Clinical observations at home or at work are more convenient and usually less stressful for families. Natural setting observation is time-consuming and therefore costly. Even if the observation itself is not that lengthy, travel to and from the site adds to the professional's time commitment. As a result, agencies and insurance companies are less likely to subsidize this assessment method. Another disadvantage is that the presenting problem simply may not occur during the observation period.
