Distinct Associations of Alexithymia Dimensions with Youth Psychopathology and the General Factor of Psychopathology

This study of 255 youth and 142 parents demonstrates that while both difficulties identifying and describing feelings are linked to broad psychopathology, the former is a stronger predictor of emotional distress and internalizing problems, supporting alexithymia's role as a distress-centered transdiagnostic correlate of adolescent mental health difficulties.

Imagine your emotions are a secret language your body is constantly trying to speak to you. Sometimes, the message gets garbled. You feel a tightness in your chest or a knot in your stomach, but you can't quite name the feeling. Is it anger? Sadness? Fear? Or just "bad vibes"? This confusion is what researchers call alexithymia.

In a new study, scientists looked at 255 teenagers (aged 11–18) and 142 of their parents to see how this "emotional confusion" connects to mental health struggles. They didn't just look at alexithymia as one big blob; they split it into two main characters in the story:

DIF (Difficulties Identifying Feelings): The trouble of knowing what you feel. It's like having a radio with static—you know something is playing, but you can't tune in to the station.
DDF (Difficulties Describing Feelings): The trouble of saying what you feel. You know the station, but you've lost the vocabulary to explain the song to your friends.

The Main Discovery: The "Distress" Connection

The study found that both DIF and DDF are linked to a wide range of mental health challenges, from anxiety and panic to feeling physically sick without a clear medical cause. However, they aren't equal players.

DIF (The "What am I feeling?" problem) was the superstar of the bad news. It had the strongest links to emotional distress, somatic (body) symptoms, and internalizing problems (like depression and anxiety). The data suggests that if a teenager can't identify their feelings, they are much more likely to feel overwhelmed by general distress and physical symptoms.

DDF (The "How do I say it?" problem) was also linked to mental health struggles, but its pattern was different. It was less strongly tied to raw emotional pain and more relevant in social situations. The study suggests that while DIF is about the internal storm, DDF is about the difficulty of sharing that storm with others. Interestingly, for social problems and school-related issues, the difference between DIF and DDF wasn't statistically significant, implying that both getting confused about feelings and struggling to talk about them can mess up your social life.

The Big Picture: A "General Factor" or Just "Distress"?

One of the coolest parts of the study was asking: Is alexithymia a general key that unlocks every type of mental health problem, or is it specific to certain ones?

Using advanced statistical models (called bifactor models), the researchers tested if alexithymia was connected to a "General Factor of Psychopathology" (a theoretical "p-factor" that represents a general vulnerability to any mental illness).

Here is the twist: The study suggests that alexithymia is linked to a general factor, but it's not a neutral, all-purpose key. Instead, it acts like a distress-centered key.

What it is linked to: Strongly connected to shared "distress" (anxiety, depression, panic, and feeling physically unwell).
What it is NOT linked to: The study found that alexithymia was not strongly linked to externalizing problems (like breaking rules or being aggressive) once the distress factor was accounted for.

In other words, the data suggests that the reason alexithymia seems to show up everywhere is because it is deeply tied to the experience of distress, not because it causes every single type of mental health issue in the same way.

The Parent Perspective: Seeing the Symptoms, Not the Storm

The researchers also asked parents to fill out surveys about their children. The results were similar to the teens' own reports but weaker.

This makes sense. Parents can see the "symptoms" of the storm—like a teen slamming a door, withdrawing from friends, or complaining of a stomach ache. But they can't hear the static on the teen's internal radio. The study notes that parents might notice the behavioral fallout of alexithymia (like irritability or trouble at school) but miss the internal confusion about emotions that the teen is experiencing.

What the Study Rules Out (and What It Doesn't)

It is important to know what this study did not find:

It did not find that the "Externally Oriented Thinking" (EOT) dimension of alexithymia (focusing on the outside world rather than inside feelings) was a reliable factor in this group. The data for this specific part was too shaky (low reliability), so the researchers set it aside to focus on the two core emotional dimensions (DIF and DDF).
It did not prove that alexithymia causes mental health problems. Because this was a "snapshot" study (looking at data from one specific time in March–June 2025), we can't say for sure if the emotional confusion came first, or if the mental health struggles made the confusion worse. The study suggests a strong link, but it doesn't solve the "chicken or egg" mystery.

The Takeaway

Think of alexithymia not as a single monster, but as two different types of glitches in the emotional operating system. One glitch (DIF) makes the whole system feel like it's overheating with distress. The other glitch (DDF) makes it hard to send error messages to your friends and family.

The study suggests that for teenagers, these glitches are a major transdiagnostic correlate—meaning they are a common thread running through many different mental health difficulties, specifically those related to distress. While we don't know the exact cause-and-effect yet, the findings highlight that helping teens learn to identify and describe their feelings might be a powerful way to tackle a broad range of mental health challenges.

The Numbers:

255 children and adolescents (aged 11–18).
142 parents.
Cronbach's α = .84 for DIF (a strong reliability score).
Cronbach's α = .70 for DDF (a good reliability score).
Cronbach's α = .27 for EOT (too low to use, so it was dropped).
Correlations between alexithymia and mental health indicators ranged from 0.31 to 0.71 for teens, and 0.22 to 0.44 for parents.

The authors conclude that while we need more long-term studies to understand the direction of the relationship, distinguishing between identifying and describing feelings is crucial for understanding teen mental health.

Technical Summary: Distinct Associations of Alexithymia Dimensions with Youth Psychopathology and the General Factor of Psychopathology

Problem Statement
Alexithymia, characterized by difficulties in identifying and describing emotions, is increasingly recognized as a marker of affective dysregulation in youth mental health. However, existing literature lacks clarity on how its core dimensions—specifically Difficulties Identifying Feelings (DIF) and Difficulties Describing Feelings (DDF)—differentially relate to various forms of psychopathology. Furthermore, it remains unclear whether alexithymia is associated with specific symptom domains or if it reflects a broader, shared liability to psychopathology (the general factor or p-factor). The study addresses these gaps by examining the distinct patterns of association between DIF and DDF and a wide range of mental health indicators, including anxiety, somatic complaints, internalizing/externalizing problems, and functional impairment, within a transdiagnostic framework.

Methodology
The study utilized a cross-sectional design with data collected from 255 children and adolescents (aged 11–18 years) and 142 parents in Slovenia.

Measures:
- Alexithymia: Youth self-report was assessed using the Alexithymia Questionnaire for Children (AQC), focusing on DIF and DDF subscales (the Externally Oriented Thinking [EOT] subscale was excluded due to poor reliability, $\alpha = .27$ ). Parent-report was assessed using the Children's Alexithymia Measure (CAM), treated as a unidimensional latent construct indicated by item parcels.
- Psychopathology: Symptoms were measured via the Screen for Child Anxiety Related Emotional Disorders (SCARED), Youth Self-Report (YSR), and Child Behavior Checklist (CBCL). Indicators included panic/somatic symptoms, generalized anxiety, social anxiety, school avoidance, internalizing (anxious/depressed, withdrawal), and externalizing (rule-breaking, aggressive) problems.
- Functioning: Health-related quality of life was measured using the Pediatric Quality of Life Inventory (PedsQL).
Analysis:
- Correlational Analysis: Non-parametric correlations and bootstrap tests were used to compare the strength of associations between DIF, DDF, and various mental health indicators.
- Structural Equation Modeling (SEM): Bifactor models were estimated to separate shared psychopathology variance (general factor) from domain-specific variance (internalizing and externalizing factors). Alexithymia was modeled as a latent factor.
- Sensitivity Analysis: Complementary bifactor-(S-1) models were employed, specifying internalizing/distress as the reference domain to interpret the general factor as "distress-centered" rather than content-neutral.

Key Results

Dimensional Distinctions: Both DIF and DDF were positively associated with a broad range of mental health difficulties. However, DIF demonstrated significantly stronger associations than DDF with emotional distress, somatic-emotional symptoms, and internalizing problems. Differences between the two dimensions were less pronounced in social and school-related domains, suggesting DDF may be more relevant to contexts requiring emotional communication and interpersonal functioning.
Transdiagnostic Association: Bifactor models indicated that alexithymia (both youth and parent reports) was positively associated with the general psychopathology factor and the specific internalizing factor. The association with the specific externalizing factor was weaker and, in parent reports, statistically non-significant.
Nature of the General Factor: Bifactor-(S-1) analyses clarified that the general factor associated with alexithymia is best understood as "distress-centered." Alexithymia showed strong associations with the general distress factor but negligible associations with residual thought/detachment or externalizing factors.
Multi-Informant Convergence: Parent-report models showed a broadly similar pattern to youth self-reports, though associations were generally weaker. This suggests that while parents observe behavioral manifestations of alexithymia-related distress, they have less access to the internal subjective experience captured by self-reports.

Significance and Claims
The paper claims that alexithymia is a distress-centered transdiagnostic correlate of adolescent mental health difficulties. By distinguishing between DIF and DDF, the study demonstrates that these dimensions are not functionally equivalent; DIF is more closely tied to the experience and differentiation of internal distress (interoceptive deficits), while DDF is more relevant to the communication of distress in social contexts.

The study situates alexithymia within hierarchical models of psychopathology (e.g., HiTOP), arguing that it represents a mechanism linked to shared variance across diverse symptom domains, specifically those related to distress and internalizing problems, rather than a content-neutral p-factor. The findings support the view that emotional awareness and differentiation are critical developmental processes, and that deficits in these areas contribute to a broad vulnerability to psychopathology, particularly internalizing and somatic-emotional difficulties.

Limitations and Cautions
The authors explicitly note that the cross-sectional design precludes causal inferences regarding whether alexithymia precedes psychopathology or arises as a consequence of distress. Additionally, the reliance on questionnaire-based measures introduces potential shared method variance, and the exclusion of the EOT dimension limits the findings to the affective dimensions of alexithymia. The interpretation of the general factor is constrained by the specific indicators selected for the model.
