Emotions are inborn within every individual. Joy, sadness, and fear are among many forms of emotions. Fear
emerges as a reaction to any threatening and dangerous objects or situations. Extreme fear of a certain object
or situation for irrational reasons and incoherent with reality is called a specific phobia. One effective therapy
to treat specific phobias is cognitive behavior therapy (CBT). This research sought to discover the
effectiveness of CBT in decreasing symptoms of specific phobias. This research hypothesized that CBT was
effective in decreasing symptoms of specific phobias, as shown in the decreased scores of a phobia of height
before and after CBT. This research's subjects were ten people with specific phobias characteristics, whose
scores were obtained using one group pretest-posttest design. The severity measure for specific phobia
adults, adapted from American Psychological Association, was the tool for collecting data; the alpha
coefficient of reliability (α) was 0.841. CBT techniques applied in this research were cognitive restructuring
in the cognitive model ABC, Socratic dialogue, and systematic desensitization. The data analysis method used
was non-parametric analysis, the Wilcoxon signed-rank. The results showed the pretest-posttest scores as
0.034 and post-test follow-up as 0.033 (p<0.05), which implied the effectivity of CBT in decreasing symptoms
of specific phobias. This study suggested that in conducting online CBT in the future, researchers may explore
more platforms or applications supporting the therapy session
