Measuring Driving Fear

Presently, there is no instrument to support the diagnosis of driving fear and its severity. To enable a reliable and valid diagnosis, the 5-item German-language Instrument for Fear of Driving (IFD) was developed. The items, by DSM-5 criteria for a specific phobia, measure the emotional, cognitive, and physiological components of driving fear as well as the degree of avoidance and impairment. The present paper comprises two studies that describe the development of the IFD and its psychometric properties. In Study 1, the IFD was administered to 810 non-clinical participants in an online survey and demonstrated good reliability and construct validity. In Study 2, fifty-four people with a clinical diagnosis, including clinically relevant driving fear, completed the IFD and a clinical interview. The IFD demonstrated good sensitivity and specificity, and a cut-off score resulted in 95% sensitivity and 97% specificity. While the findings are preliminary and further studies with larger samples are needed, the IFD is a promising screening instrument for driving fear and its severity.

It Takes a Village: The Importance of Neuropsychological Findings in a Collaborative Approach for a Patient with Congenital Central Hypoventilation Syndrome and Specific Phobia

Congenital central hypoventilation syndrome (CCHS) is a life-threatening disorder characterized by respiratory symptoms such as hypoventilation during sleep, significantly reduced ventilatory and arousal responses, and sustained hypoxia. Patients with CCHS exhibit neurocognitive deficits due to structural abnormalities in the brainstem, cerebellum, and forebrain. Due to the potential for repeated hypoxemia and hypercarbia among patients with CCHS, neurocognitive functioning is often impaired. This is the first described report in which a patient with CCHS and specific phobia has been reported and highlights the importance of neuropsychological testing in directing treatment approaches. We report a case of a 26-year-old male, diagnosed with CCHS and specific phobia. This patient was overdue for a needed bronchoscopy to check his airway for abnormalities (recommended every 12-24 months). The patient had developed a specific phobia to procedures involving anesthesia. It was determined in the initial phase of treatment that the patient’s neurocognitive status was impacting his ability to engage in psychiatric and psychosocial treatment. This patient’s care consisted of neuropsychological testing, with medication consultation, and cognitive behavioral psychotherapy. Treatment involved consistent collaboration among the patient’s treating clinicians as well as collaboration with the patient’s family and team of nurses. At the conclusion of treatment, the patient had successfully completed his bronchoscopy and future treatment goals were identified. This case emphasizes the importance of a neuropsychological evaluation when there is a disconnect in a patient’s information processing, as the results may be highly informative in directing treatment for patients with CCHS and specific phobia. The collaborative care we provided offers insights which may direct future interventions for patients with CCHS and improve their quality of life. Our case adds support to the recommendation that patients with CCHS and impaired psychosocial functioning should receive neuropsychological testing to best direct treatment.

Fear inoculation among snake experts

Background Fear acquisition of certain stimuli, such as snakes, is thought to be rapid, resistant to extinction, and easily transferable onto other similar objects. It has been hypothesized that due to increased survival chances, preparedness to instantly acquire fear towards evolutionary threats has been hardwired into neural pathways of the primate brain. Here, we compare participants’ fear of snakes according to experience; from those who often deal with snakes and even suffer snakebites to those unfamiliar with snakes. Methods The Snake Questionnaire-12 (SNAQ-12) and Specific Phobia Questionnaire (SPQ) were administered to three groups of participants with a different level of experience with snakes and snakebites: 1) snake experts, 2) firefighters, and 3) college students. Results This study shows that individuals more experienced with snakes demonstrate lower fear. Moreover, participants who have suffered a snakebite (either venomous or not) score lower on fear of snakes (SNAQ-12), but not of all other potentially phobic stimuli (SPQ). Conclusions Our results suggest that a harmless benign exposure might immunize people to highly biologically prepared fears of evolutionary threats, such as snakes.

Beyond exposure therapy: formulation-based therapy treating a fear of urinary incontinence – a case study

Background: The current literature on the specific phobia of urinary incontinence is limited, with no specific empirically established model or treatment protocol. Aims: This article consists of a case study of formulation-driven cognitive behaviour therapy (CBT) for phobia of urinary incontinence. Method: Martin attended a total of 12 treatment sessions. The treatment included the development of an idiosyncratic formulation, and the use of well-established cognitive and behavioural treatment strategies from other anxiety disorders. Results: Both outcome measures and Martin’s subjective report indicate that the treatment was effective. Conclusion: This case study contributes to the current limited literature on this phobia, and emphasises the importance of formulation-driven CBT to map for idiosyncratic features and target cognitive and behavioural factors.

Changes in Brain Activation through Cognitive-Behavioral Therapy with Exposure to Virtual Reality: A Neuroimaging Study of Specific Phobia

Background: Cognitive-behavioral therapy (CBT) with exposure is the treatment of choice for specific phobia. Virtual reality exposure therapy (VRET) has shown benefits for the treatment and prevention of the return of fear in specific phobias by addressing the therapeutic limitations of exposure to real images. Method: Thirty-one participants with specific phobias to small animals were included: 14 were treated with CBT + VRET (intervention group), and 17 were treated with CBT + exposure to real images (active control group). Participants’ scores in anxiety and phobia levels were measured at baseline, post-treatment, and 3-month follow-up, and brain activation was measured through functional magnetic resonance imaging (fMRI) baseline and post-treatment. Results: Both groups showed a significant decrease in anxiety and phobia scores after the therapy and were maintained until follow-up. There were no significant differences between both groups. Overall, fMRI tests showed a significant decrease in brain activity after treatment in some structures (e.g., prefrontal and frontal cortex) and other structures (e.g., precuneus) showed an increasing activity after therapy. However, structures such as the amygdala remained active in both groups. Conclusions: The efficacy of CBT + VRET was observed in the significant decrease in anxiety responses. However, the results of brain activity observed suggest that there was still a fear response in the brain, despite the significant decrease in subjective anxiety levels.
