I don't want you to take my word for it, as i'm only making educated guesses. So I will list the "Diagnostic Criteria" of AvPD according to my DSM-IV-TR (slightly outdated manual but...) if that helps any.
A pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation , beginning by early adulthood and present in a variety of contexts, as indicated by four (or more) of the following.
(1) avoids occupational activities that involve significant interpersonal contact, because of fears of criticicm, dissapproval, or rejection.
(2) is unwilling to get involved with people unless certain of being liked.
(3) shows restraint within intimate relationships because of fear of being shamed or ridiculed.
(4) is preoccupied with being criticized or rejected in social situations.
(5) is inhibited in new interpersonal situations because of feelings of inadequacy.
(6) veiws self as socially inept, personally unappealing, or inferior to others.
(7) is usually reluctant to take personal risks or to engage in any new activities because they may prove embarrassing.
And as it is a "Personality Disorder" versus an "Anxiety Disorder" also see "General Diagnostic Criteria for a Personality Disorder"
A. An enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual's culture. This deviation is manifested in two (or more) of the following areas.
(1) cognition (that is, ways of perceiving and interpreting self, other people, and events)
(2) affectivity (that is, the range, intensity, lability, and appropriateness of emotional response)
(3) interpersonal functioning
(4) impulse control
B. The enduring pattern is inflexible and pervasive across a broad range of personal and social situations.
C. The enduring pattern leads to clinically significant distress or impairment in social, occupational, or other important areas of functioning.
D. The pattern is stable and of long duration and its onset can be traced back at least to adolescence or early childhood.
(And Note E)
E. The enduring pattern is not better accounted for as a manifestation or consequence of another mental disorder.
F. The enduring pattern is not due to the direct physiological effects of a substance (for example, a drug of abuse, a medication) or a general medical condition (for example, a head trauma).
Other notes in the manual state that "Avoidant Personality Disorder is frequently present in individuals with Social Phobia, Generalized"
"Other disorders that are commonly diagnosed with Avoidant Personality Disorder include Mood and Anxiety Disorders (especially Social Phobia of the Generalized type)"
