Summary
The Persian version of the Adult Disorganized Attachment Scale (ADA) is reliable and valid for use in Iran. This short scale is practical for clinical and research settings, aiding in the assessment of attachment styles.
Area of Science:
- Psychology
- Clinical Psychology
- Psychometrics
Background:
- Attachment theory is crucial for understanding adult relationships.
- Disorganized attachment is associated with various psychological difficulties.
- A validated Persian measure of adult disorganized attachment is needed.
Purpose of the Study:
- To translate and culturally adapt the Adult Disorganized Attachment Scale (ADA) into Persian.
- To evaluate the psychometric properties of the Persian version of the ADA.
- To provide a reliable and valid instrument for assessing disorganized attachment in Persian-speaking populations.
Main Methods:
- The study involved 202 university students (61.4% female, aged 17-36).
- Convergent validity was assessed using the Experience in Close Relationships measure.
- Criterion validity was examined with the Sadism Scale and Shutdown Dissociation Scale.
- Reliability (Cronbach's alpha) and construct validity (Confirmatory Factor Analysis) were analyzed using SPSS and LISREL.
Main Results:
- The Persian ADA demonstrated strong reliability (Cronbach's alpha = 0.82).
- Good convergent validity was found, with significant positive correlations to Shutdown Dissociation, Anxious Attachment, Avoidant Attachment, and Sadism (p < 0.05).
- Confirmatory Factor Analysis supported the structural validity with excellent fit indices (χ²/df = 1.44, RMSEA = 0.047, CFI = 0.98, GFI = 0.96).
Conclusions:
- The Persian version of the Adult Disorganized Attachment Scale is a psychometrically sound instrument.
- The scale is a short, practical tool suitable for clinical and research applications in Iran.
- This validated scale will facilitate the study of disorganized attachment within the Persian-speaking population.

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Attachment theory, developed initially to explain infant–caregiver bonds, has been extended to illuminate patterns of intimacy in adult romantic relationships. Psychologists Cindy Hazan and Phillip Shaver proposed that the attachment styles observed in infancy form a framework for how individuals approach emotional closeness and conflict in adulthood. These attachment styles—secure, avoidant, and anxious—are linked to enduring patterns of behavior and emotional regulation in...

Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that...

Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...

Diana Baumrind's four parenting styles — authoritarian, authoritative, neglectful, and permissive — each influence children's socio-emotional development differently.
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
