Considering the NSSI among the groups, there were 16 outpatients (16 out of 42) in the social phobia group, 7 outpatients (7 out of 29) in the agoraphobia group, 14 outpatients (14 out of 40) in the simple phobia group, and 6 healthy controls (6 out of 52) in the control group, who responded as "yes" to the screening questions in the first part of the ISAS, indicating the NSSI.
Table 5 presents the correlation between the anxiety sensitivity and the NSSI characteristics of the agoraphobia and simple phobia groups.
The present study aimed to investigate the characteristics of impulsivity, anxiety sensitivity, and the NSSI of outpatients with social phobia, agoraphobia or a simple phobia, and to compare these characteristics within groups and healthy controls through self-reported scales.
Previous studies in the literature have reported that simple phobia is a common emerging fear in early childhood, social fears in adolescence, and agoraphobia in early adulthood (22-24).
The LOD score was only 2 in a broader anxiety disorder sample of 62 Icelandic families with diagnoses including panic disorder, agoraphobia, simple phobia, social phobia, generalized anxiety disorder, and somatoform pain, which was highly comorbid with anxiety in the sample (Am.
They also found potential linkages at chromosome 1 for panic disorder alone, chromosome 3 for agoraphobia, chromosome 11 for panic disorder and habitual smoking, and chromosome 16 for both social phobia and simple phobia.
A significant linkage was found at chromosome 14 for simple phobia, and possible linkages for social phobia, panic disorder, and agoraphobia.
