BCIA Clinical Applications for Anxiety and Depression 2 — Questions and Answers
Question 1: The 'frontal alpha asymmetry' neurofeedback protocol for depression primarily aims to:
- Increase bilateral frontal alpha power equally
- Increase left frontal activation relative to right, associated with positive affect and approach motivation (Correct answer)
- Decrease all frontal activity to reduce rumination
- Increase right frontal beta to enhance executive function
Correct answer: Increase left frontal activation relative to right, associated with positive affect and approach motivation
Left frontal hypoactivation (reflected as higher left alpha) is associated with depression and reduced approach motivation. The protocol targets increasing left frontal activation relative to right.
Question 2: In biofeedback for social anxiety disorder, which intervention addresses the somatic symptoms of blushing and elevated heart rate most directly?
- Alpha/theta neurofeedback at Oz
- Combined HRV biofeedback and peripheral temperature training (Correct answer)
- SMR uptraining at Cz for motor inhibition
- Delta downtraining to improve sleep quality
Correct answer: Combined HRV biofeedback and peripheral temperature training
Social anxiety's somatic symptoms (blushing, tachycardia) are driven by sympathetic hyperreactivity. HRV biofeedback and thermal training address peripheral vasomotor and cardiac regulation directly.
Question 3: Research on biofeedback for depression generally shows effects on which outcome domains?
- Only cognitive symptoms with no physiological change
- Mood, HRV, frontal EEG asymmetry, and rumination reduction (Correct answer)
- Exclusively sleep architecture improvement
- Motor coordination only
Correct answer: Mood, HRV, frontal EEG asymmetry, and rumination reduction
Biofeedback research for depression demonstrates multi-domain effects including improved mood, normalized frontal EEG asymmetry, increased HRV, and reduced rumination.
Question 4: Psychophysiological stress profiling in an anxious client would most likely reveal:
- Low baseline EMG, high finger temperature, and elevated HRV
- High baseline EMG, low finger temperature, low HRV, and elevated GSR (Correct answer)
- Normal HRV with selective theta elevation only
- Uniform suppression of all measured parameters
Correct answer: High baseline EMG, low finger temperature, low HRV, and elevated GSR
Anxious individuals typically show elevated baseline muscle tension (high EMG), reduced peripheral blood flow (low finger temperature), sympathetic dominance (low HRV), and elevated electrodermal activity.
Question 5: Which statement best describes the role of interoception in biofeedback treatment for anxiety?
- Interoception is irrelevant to biofeedback outcomes
- Biofeedback enhances interoceptive awareness, helping clients accurately perceive and regulate bodily anxiety signals (Correct answer)
- Improving interoception always worsens anxiety by increasing somatic awareness
- Interoception only applies to neurofeedback, not peripheral biofeedback
Correct answer: Biofeedback enhances interoceptive awareness, helping clients accurately perceive and regulate bodily anxiety signals
Biofeedback enhances interoceptive awareness — the ability to perceive internal body signals — which is central to anxiety management by enabling clients to detect and regulate early physiological anxiety cues.
Question 6: When treating PTSD with biofeedback, which approach incorporates trauma processing alongside physiological down-regulation?
- SMR/beta neurofeedback alone at Cz
- Alpha/theta neurofeedback, sometimes integrated with trauma-focused therapy (Correct answer)
- High-frequency HRV training at 10 breaths/min
- Isolated GSR uptraining
Correct answer: Alpha/theta neurofeedback, sometimes integrated with trauma-focused therapy
Alpha/theta neurofeedback, developed by Peniston and Kulkosky, is specifically associated with PTSD treatment, using the hypnagogic theta state to facilitate trauma processing alongside physiological relaxation.
