Introduction: The Discovery of a Unique Psychological Phenomenon
In 2002, a groundbreaking paper published in the Journal of Contemporary Psychotherapy introduced the world to a previously unnamed psychological phenomenon: maladaptive daydreaming. The term was coined by Professor Eli Somer of the University of Haifa, Israel, who described it as “extensive fantasy activity that replaces human interaction and/or interferes with academic, interpersonal, or vocational functioning.” This initial qualitative study examined six patients who exhibited this distinctive pattern of excessive, immersive daydreaming that significantly disrupted their daily lives.
This article provides a comprehensive overview of the scientific research on maladaptive daydreaming conducted over the past two decades, from its initial identification to current understanding of prevalence, assessment methods, potential causes, and treatment approaches.
Early Research and Conceptualization
Somer’s Initial Observations
Somer’s 2002 qualitative inquiry was based on observations from his clinical practice, where he identified six trauma patients who engaged in extensive fantasy activity that appeared to function as a coping mechanism but had become problematic in their lives. Through cross-sectional analysis of interview transcripts, Somer identified key functions of this daydreaming, including:
- Disengagement from stress and pain
- Mood enhancement through wish fulfillment
- Creation of companionship and intimacy
- Self-soothing
Common themes in these daydreams included violence, idealized self-representations, power and control scenarios, captivity, rescue and escape narratives, and sexual arousal. Notably, many participants reported physical movements (such as pacing or rocking) that accompanied and enhanced their daydreaming experiences.
While all participants appeared to have a normal childhood propensity for creative imagination, Somer noted that adverse or traumatic circumstances seemed to contribute to the development of what he termed maladaptive daydreaming (MD).
Early Follow-Up Studies
For several years following Somer’s initial paper, research on maladaptive daydreaming remained limited to case studies and small-scale investigations. However, these early explorations helped establish the phenomenon as distinct from normal daydreaming and other psychological conditions.
A notable advancement came in 2011 when researchers Jayne Bigelsen and Cynthia Schupak published a study of 90 self-identified maladaptive daydreamers who had responded to online announcements. This larger sample helped confirm the core features of MD and highlighted that while some participants reported childhood trauma (27%), many did not, suggesting that trauma was not a necessary precondition for developing maladaptive daydreaming.
Assessment and Measurement Development
The Maladaptive Daydreaming Scale (MDS)
A critical milestone in MD research came in 2016 with the development and validation of the Maladaptive Daydreaming Scale (MDS) by Somer and colleagues. This 16-item self-report measure was designed to identify and quantify maladaptive daydreaming. The scale assesses various aspects of daydreaming, including:
- Quality (vividness, complexity)
- Control (ability to stop or limit daydreaming)
- Distress (negative emotions about daydreaming habits)
- Benefits (positive emotions during daydreaming)
- Interference (impact on daily functioning)
The MDS has demonstrated strong psychometric properties with high internal consistency and good convergent and divergent validity. The scale has been translated into numerous languages and has become the standard assessment tool in MD research. A total score of 40 or higher on the MDS indicates suspected clinical-level maladaptive daydreaming.
Structured Clinical Interview for Maladaptive Daydreaming (SCIMD)
Building on the MDS, researchers developed the Structured Clinical Interview for Maladaptive Daydreaming (SCIMD) in 2017. This clinician-administered diagnostic interview was designed to assess the proposed diagnostic criteria for MD. Studies have shown good to excellent agreement between the MDS and SCIMD, supporting the validity of both assessment methods.
More recently, researchers have developed shorter screening tools such as the Maladaptive Daydreaming Scale Short Form (MD-SF5), a five-item measure that shows good agreement with the full MDS and can be used for efficient screening in larger population studies.
Epidemiological Research and Prevalence
Prevalence Estimates
Until recently, most MD research relied on self-selected samples of individuals who identified with the condition, making it difficult to estimate true prevalence rates in the general population. However, recent epidemiological studies have begun to address this gap.
A 2021 study using representative sampling in Israel found that approximately 2.5% of the general population meets criteria for clinical-level maladaptive daydreaming. Rates were higher (around 5.5-8.5%) when focusing on young adult and student populations, suggesting a potential age effect.
Another study from 2023 using a large U.S. sample found similar prevalence rates, with maladaptive daydreaming appearing to be more common among younger adults and those with certain psychiatric conditions.
Demographic and Clinical Associations
Research has identified several factors associated with increased likelihood of maladaptive daydreaming:
- Age: MD appears more common in adolescents and young adults
- Comorbidities: Higher rates in individuals with ADHD (estimated at 20% of adults with ADHD), OCD, anxiety disorders, and dissociative disorders
- Trauma: While not necessary for developing MD, childhood trauma appears to be a risk factor for some individuals
Interestingly, the association between maladaptive daydreaming and general intelligence or creativity remains unclear, with some studies suggesting that individuals with MD may have enhanced creative abilities while still experiencing significant distress and impairment from their daydreaming.
Phenomenology and Clinical Features
Core Characteristics
Through extensive research, several defining features of maladaptive daydreaming have been consistently observed:
Immersiveness: MD involves highly detailed, complex, and vivid fantasy worlds, often with ongoing storylines and characters that develop over months or years.
Duration: Individuals with MD typically spend several hours daily engaged in daydreaming (commonly 4-8 hours).
Kinesthetic Elements: Many individuals with MD engage in repetitive movements (pacing, rocking, hand gestures) or mouthing words while daydreaming, which appears to enhance the immersive experience.
Music Facilitation: A strong association with music has been documented, with many reporting that specific music triggers or intensifies their daydreaming episodes.
Awareness of Fantasy: Unlike psychotic conditions, individuals with MD maintain awareness that their daydreams are not real.
Compulsivity: Many experience an addictive quality to their daydreaming, with urges to daydream, difficulties controlling the behavior, and distress when prevented from engaging in it.
Interference: MD significantly impacts daily functioning, relationships, and responsibilities.
Relationship to Other Conditions
Research has explored the relationship between maladaptive daydreaming and various psychological conditions:
Dissociative Disorders: While MD involves a form of dissociative absorption, it differs from dissociative identity disorder (DID) in that MD involves deliberate fantasy rather than identity fragmentation. However, a 2020 study found high comorbidity rates, with 49% of patients in a trauma unit having MD alongside dissociative disorders.
ADHD: Significant overlap exists, particularly with inattentive-type ADHD, though the nature of attention in MD (hyperfocus on fantasy) differs from typical ADHD presentations.
OCD: Similarities exist in the compulsive quality and difficulty controlling the behavior, with some MD patients responding to OCD treatments.
Anxiety and Depression: Strong associations exist, with MD often functioning as an escape from negative emotions.
Research suggests MD may be a distinct condition rather than simply a symptom of these other disorders, as many individuals with MD do not meet criteria for other diagnoses that would explain their symptoms.
Neurobiological and Psychological Mechanisms
Neurological Basis
While neuroimaging studies of MD specifically remain limited, researchers have proposed that MD likely involves alterations in the default mode network (DMN)—brain regions active during rest and internal reflection. Preliminary evidence suggests MD may involve:
- Hyperactivity in the DMN
- Altered connectivity between the DMN and executive control networks
- Dysregulation in dopaminergic reward pathways
The role of movement in facilitating daydreaming suggests potential involvement of motor circuits and their integration with imagination networks.
Psychological Mechanisms
Several psychological mechanisms have been proposed to explain the development and maintenance of maladaptive daydreaming:
Coping and Escape: MD often begins as an adaptive coping strategy for managing stress, trauma, loneliness, or adverse environments.
Reinforcement: The pleasurable, immersive nature of daydreaming provides positive reinforcement, while the relief from negative emotions offers negative reinforcement, creating a cycle similar to behavioral addictions.
Dissociation: MD may represent a specific form of dissociative absorption that becomes problematic when overused.
Maladaptive Emotion Regulation: Research suggests MD may develop as an emotion regulation strategy that becomes the primary or exclusive means of managing difficult feelings.
Executive Function Deficits: Difficulties with inhibitory control and attention regulation appear to contribute to the inability to limit daydreaming despite negative consequences.
Treatment Approaches and Research
Current Treatment Evidence
Research on effective treatments for maladaptive daydreaming remains in early stages, with most evidence coming from case studies and small trials. Approaches that have shown preliminary effectiveness include:
Cognitive-Behavioral Therapy (CBT): Techniques focusing on identifying triggers, developing alternative coping strategies, and gradually reducing daydreaming time have shown promise in case reports.
Schema Therapy: This integrative approach shows promise for maladaptive daydreaming, particularly when the condition is connected to early unmet emotional needs or childhood experiences:
- Identifies early maladaptive schemas (emotional patterns) that may drive daydreaming as a coping mechanism
- Uses the concept of “modes” to understand the emotional states that trigger retreat into fantasy
- Employs experiential techniques like imagery rescripting that can transform daydream content
- Limited reparenting techniques may address the core emotional needs that drive fantasy escapism
- May be particularly valuable when daydream content reflects specific unmet childhood needs
Eye Movement Desensitization and Reprocessing (EMDR): When trauma underlies maladaptive daydreaming, EMDR offers potential benefits:
- Processes traumatic memories that may serve as triggers for escapist daydreaming
- Reduces the emotional charge of memories that prompt dissociation into fantasy
- Uses bilateral stimulation (eye movements, taps, or tones) to integrate fragmented traumatic experiences
- May diminish the need for fantasy as a coping mechanism by healing underlying trauma
- Can be combined with other approaches in a comprehensive treatment plan
Mindfulness-Based Interventions: Practices that enhance present-moment awareness may help individuals recognize when they’re slipping into daydreams and make conscious choices about their attention.
Medication: Some case studies suggest that medications used for OCD and ADHD may be helpful for some individuals. One case report documented significant improvement with fluvoxamine, an SSRI medication commonly used for OCD.
Self-Help Strategies
In the absence of established clinical treatments, many individuals with MD have developed their own management strategies, which researchers have begun to examine systematically:
- Keeping a daydreaming journal to build awareness
- Limiting exposure to triggers (certain music, media, or environments)
- Scheduling limited “daydreaming time” rather than attempting complete elimination
- Physical activities that require full attention and presence
- Building social connections to reduce isolation
- Gradual reduction in daydreaming time
Current Diagnostic Status and Future Directions
Recognition as a Disorder
Maladaptive daydreaming is not currently recognized as an official disorder in diagnostic manuals such as the DSM-5-TR or ICD-11. However, growing research evidence supports its consideration as a distinct condition:
The non-normal distribution of MD symptoms in general population samples suggests it represents a distinct condition rather than an extreme on a normal daydreaming continuum.
Longitudinal research has demonstrated the stability of MD over time, supporting its conceptualization as a chronic condition rather than a transient state.
The significant distress and functional impairment associated with MD meets general criteria for mental disorder classification
Researchers have proposed specific diagnostic criteria for maladaptive daydreaming that include:
- Excessive daydreaming that causes distress or impairment
- Daydreams that are vivid, detailed, and immersive
- Strong urge or compulsion to continue daydreaming
- Difficulty controlling or limiting daydreaming
- Interference with social, academic, or occupational functioning
- Not better explained by another disorder or substance use
Ongoing Research and Future Directions
Current MD research is expanding in several important directions:
Neuroimaging Studies: Researchers are beginning to use brain imaging techniques to better understand the neural correlates of maladaptive daydreaming.
Longitudinal Research: Studies examining the course of MD over time are helping to clarify whether it represents a stable trait and how it relates to other psychological symptoms.
Treatment Trials: Formal clinical trials of various therapeutic approaches are underway to develop evidence-based treatments.
Cross-Cultural Research: Studies across different cultures are examining whether MD manifests similarly across diverse populations.
Developmental Trajectories: Research on the onset and development of MD is exploring how and why some children with vivid imaginations develop problematic daydreaming while others do not.
Community and Advocacy
The internet has played a crucial role in connecting individuals with maladaptive daydreaming, with online communities providing support, validation, and information sharing. These communities have been instrumental in raising awareness of the condition and advocating for its recognition.
The International Consortium for Maladaptive Daydreaming Research (ICMDR), founded by Eli Somer, brings together researchers from around the world to advance scientific understanding of the condition. The consortium’s website provides resources including assessment tools and research publications.
Growing media attention has also increased public awareness of maladaptive daydreaming in recent years, helping more individuals recognize their experiences and seek support.
Conclusion: A Condition Emerging from the Shadows
In the two decades since Eli Somer first identified and named maladaptive daydreaming, research has transformed our understanding of this condition from an obscure curiosity to a well-documented psychological phenomenon affecting millions worldwide. Evidence increasingly supports its conceptualization as a distinct mental health condition with specific diagnostic features, assessment methods, and potential treatments.
While significant questions remain about optimal treatment approaches, neurobiological mechanisms, and the condition’s relationship to other psychological disorders, the growing body of research has validated the experiences of countless individuals who previously lacked a name for their immersive daydreaming experiences and the problems they cause.
As research continues to advance, there is hope that maladaptive daydreaming will gain official recognition in diagnostic systems, leading to increased clinical awareness, improved treatment options, and better outcomes for those affected by this unique condition.
