This study describes the natural course of social phobia as recalled by a sample of nonclinical subjects and explores, using qualitative research methods, perceived risk factors and factors that may cause changes in its course. Thirty-nine respondents with a lifetime diagnosis of social phobia were interviewed using a semistructured interview schedule based on DSM-IV criteria. Four main lifetime patterns emerged: a slight worsening of social phobic symptoms over time, no change, slight improvement and complete remission. Thirty-eight percent of the sample was in remission at the time of interview. The mean age of onset was 12.8 +/- 4.1 years. The average duration of illness was 29.0 +/- 12.7 years. Factors perceived by respondents to precipitate social phobia, using contract analysis, were family and school environment, onset of adolescence, low self-esteem, temperament and poverty. Factors perceived to improve symptoms were building self-esteem, exposure, determination, maturity and counseling. Factors perceived to worsen symptoms were avoidance, exposure to negative attention and comorbid disorders.
