Abstract
Background: Misophonia is an unpleasant condition in which the feeling of excessive anger is triggered by specific sounds. The main objective of the present study was to investigate the effectiveness of cognitive-behavioral therapy (CBT) on anger in female students with misophonia.
Methods: A study based on a non-concurrent multiple baseline design was conducted in 2018 at the School of Education and Psychology, Shahid Chamran University of Ahvaz, Ahvaz, Iran. Three female students aged 20-22 years were recruited using the multi-stage random sampling method. The study was conducted in three stages, namely baseline, intervention, and follow-up sessions. The Novaco anger questionnaire was used during the baseline sessions, intervention sessions (sessions 3, 6, and 8), and 6 weeks follow-up (2, 4, and 6 weeks after the last intervention session). Data were analyzed using visual analysis, reliability change index (RCI), and recovery percentage formula.
Results: CBT reduced the feeling of anger after the intervention and follow-up sessions. The recovery percentage at the end of the intervention sessions were 43.82, 42.28, and 9.09 for the first, second, and third participants, respectively.
Conclusion: The findings of the present study confirm the effectiveness of CBT in reducing the feeling of anger in female students with misophonia.

| Background/Purpose | Background- Purpose- • assess the efficacy of CBT on the anger of females with misophonia |
| Participants/samples | • Initial sample: 320 female dormitory students (multi-stage random sampling). • 65 students scored ≥7 on MQ (cut-off). • 27 interviewed using Schroder diagnostic criteria. • 11 met inclusion criteria. • 4 randomly selected; 1 withdrew; final N=3. • Age range: 20–22 years. • Inclusion: MQ ≥7, diagnosed with misophonia, willingness to participate. • Exclusion: psychiatric/psychotropic drug use within 6 months; concurrent psychotherapy. |
| Measures | • Misophonia Questionnaire (MQ); Cronbach’s alpha (current study): total=0.90; MSS=0.75; MEBS=0.90. • Novaco Anger Scale (NAS); Cronbach’s alpha (current study)=0.91. • Clinical interview using Schroder criteria. |
| Procedures | • Design: non-concurrent multiple baseline single-case experimental design. • Stages: baseline, intervention, follow-up. • Intervention: 8 weekly sessions, 60 minutes each. • NAS administered during baseline, sessions 3, 6, 8, and at 2-, 4-, 6-week follow-up. • Intervention components: • Psychoeducation on misophonia. • Hierarchical identification of auditory triggers. • Identification of adaptive/maladaptive coping strategies. • Task concentration exercises. • Relaxation and breathing training. • Manipulation of auditory stimuli (pitch/interval alteration). • Direct exposure to aversive sounds. |
| Results | anger score changes • Baseline mean anger: P1=73.0; P2=65.25; P3=48.4 • Post-intervention mean anger: P1=41.0; P2=37.66; P3=44.0 • Follow-up mean anger: P1=21.33; P2=28.33; P3=45.66 • P1 and P2 showed sustained reductions; P3 showed minimal change with increase at follow-up. recovery percentage • Post-intervention: P1=43.83%; P2=42.28%; P3=9.09%; overall=31.73% • Follow-up: P1=70.78%; P2=56.58%; P3=5.66%; overall=44.34% reliability change index (RCI) • Post-intervention: P1=6.55; P2=6.56; P3=2.73 • Follow-up: P1=10.58; P2=8.79; P3=1.70 visual analysis • PND=100%; POD=0% for all participants. • Stability reported across stages. |
| Discussion/Limits | Conclusion- • CBT reduced anger symptoms in participants with misophonia. • Anger scores at follow-up below baseline levels. • Discontinuation of exercises over time may reduce effectiveness. |
| Limitations:: | • Single-sex (female-only) sample. • Single-case intervention design. • Limited generalizability. |
| Future Directions:: | |
| Relevance:: | • provides (weak) evidence for the effectiveness of CBT in treating misophonia |

- this sample size is so small to the point where i am not even sure this is worth noting.
