Subtype | Characteristics | Life History | Personality Traits | Sleep Patterns | Treatment Focus |
---|---|---|---|---|---|
Highly Distressed Insomnia | Significant emotional distress (anxiety, depression). | Chronic stress, trauma, significant life events. | High neuroticism, low resilience. | Severe difficulties in falling asleep, maintaining sleep, or early awakenings. | CBT-I + psychotherapy, possibly medication for anxiety/depression. |
Moderately Distressed Reward-Sensitive Insomnia | Moderate distress, high sensitivity to rewards and positive stimuli. | Mood instability, impulsivity history. | High extraversion, high reward sensitivity. | Sleep difficulties linked to mood fluctuations and reward-seeking behaviors. | Behavioral interventions for mood stabilization, CBT-I, and pharmacological support for mood stabilization. |
Moderately Distressed Reward-Insensitive Insomnia | Moderate distress, low sensitivity to rewards. | Stable background with moderate chronic stress. | Low neuroticism, high conscientiousness. | Consistent sleep difficulties without mood swings or significant stressors. | CBT-I focusing on sleep hygiene, relaxation, stress reduction. Minimal pharmacotherapy unless coexisting depression. |
Slightly Distressed Low Reactive Insomnia | Low emotional distress, low reactivity to stress. | Stable life history, minimal significant stress. | High resilience, low neuroticism. | Mild insomnia, consistent and long-standing, without external disturbances. | Behavioral approaches: sleep hygiene, cognitive restructuring, relaxation techniques. Minimal pharmacotherapy. |
Slightly Distressed High Reactive Insomnia | Low distress, high sensitivity to stressors and environmental changes. | Situational stress history, no chronic psychological conditions. | High openness, sensitivity to environmental changes. | Sleep disturbances triggered by stressors, routine changes, environmental factors. | Stress management, enhancing sleep environment, relaxation exercises, CBT-I to improve coping mechanisms. |
