Discuss observation as a source of information that social workers use for assessments.

Answers may vary. The information obtained from client interviews is usually the primary source of assessment information. Direct observation of nonverbal behavior adds information about emotional states and reactions such as anger, hurt, embarrassment, and fear. To use these sources of data, the social worker must be attentive to nonverbal cues, such as tone of voice, tears, clenched fists, vocal tremors, quivering hands, a tightened jaw, pursed lips, variations of expression, and gestures; he or she must link these behaviors to the topic or theme during which they arise.
Observations of interactions between spouses or partners, family members, and group members are also often enlightening. Social workers may be surprised at the differences in people's reports of their relationships and the behaviors they actually demonstrate in those relationships. Observation can occur in natural settings. Home visits are a particularly helpful forum for observation. One major benefit of in-home, family-based services is the opportunity to observe the family's lived experiences firsthand rather than rely on second-hand accounts. Observing clients' living conditions typically reveals resources and challenges that would otherwise not come to light.
