Problematic online behaviors (POBs) are distinct entities, not a single addiction. This study supports the spectrum hypothesis, showing six POBs exist as separate but related issues with little overlap.
Area of Science:
- Psychology
- Behavioral Science
- Digital Health
Background:
- The conceptualization of problematic Internet or smartphone use and addiction is debated.
- The spectrum hypothesis suggests problematic online behaviors (POBs) exist on a continuum.
- Preliminary support exists for the spectrum hypothesis, but more research is needed.
Purpose of the Study:
- To empirically test the spectrum hypothesis of POBs.
- To investigate the relationships between various types of POBs.
- To determine if POBs are distinct entities or overlapping phenomena.
Main Methods:
- Network analysis approach used on an Australian community sample (n=1,617).
- Assessed six types of POBs using psychometrically validated self-report instruments.
- Computed a tetrachoric correlation matrix and performed community detection analysis.
Main Results:
- Correlations between online activities were positive and significant, but small in magnitude (0.051 ≤ r ≤ 0.236).
- Network analysis revealed six distinct communities, each corresponding to a specific POB.
- Strong internal relationships within each POB community and weaker relationships between different POBs were observed.
Conclusions:
- Findings provide further empirical support for the spectrum hypothesis.
- Suggests that problematic online behaviors (POBs) function as distinct entities.
- Indicates minimal overlap between the different types of POBs studied.

Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...
