35 Mood and Drive Dysregulation
This chapter begins the dimensional domains and how to rate severity and change. Most useful for tracking patterns over time.
35.1 Summary
- A dimensional construct describing dysregulated mood tone, energy, and drive across time and context.
35.2 Core Construct
- Instability or distortion in mood and drive that affects behavior, sleep, and function.
35.3 Subdimensions
- Low mood and loss of interest.
- Elevated mood and increased drive.
- Irritability and mixed states.
35.4 Severity Anchors (0-4)
- 0: Typical mood range and energy.
- 1: Mild shifts with limited impact.
- 2: Moderate, persistent, with clear functional impact.
- 3: Severe, recurrent or sustained, with marked impairment.
- 4: Extreme, disabling or unsafe.
35.5 Time-Course Patterns
- Episodic vs chronic.
- Cyclic or seasonal patterns.
- Trigger-linked vs autonomous shifts.
35.6 Functional Impact
- Work/school: reduced productivity or impulsive overactivity.
- Relationships: withdrawal, conflict, or instability.
- Self-care: disrupted sleep, appetite, or routine.
35.7 Developmental Expression
- Childhood: irritability, withdrawal, or behavioral change.
- Adolescence: mood lability with sleep disruption.
- Late life: mood changes with cognitive or medical overlap.
35.8 Cultural / Context Notes
- Mood expression varies with cultural norms and context.
- Grief and loss can mimic mood dysregulation.
35.9 Differential and Rule-Outs
- Substance or medication effects.
- Sleep deprivation or circadian disruption.
- Trauma-related dysregulation.
- Endocrine or neurologic contributors.
35.10 Measurement Prompts
- Brief mood or depression measure.
- Sleep/energy tracking.
35.11 Treatment-Relevant Correlates (non-prescriptive)
- High drive shifts suggest monitoring risk and sleep stability.
- Chronic low mood suggests monitoring function and withdrawal.
