Psychiatric Assessment of Preschool-Aged Children (Preschool Age Psychiatric Assessment – PAPA- OÖÇ-PD)
The Psychiatric Assessment of Preschool-Aged Children (Preschool Age Psychiatric Assessment – PAPA- OÖÇ-PD), an interview developed for the diagnosis of psychiatric symptoms and disorders in children aged 2–5 years, was developed by Egger, Ascher, and Angold in 1999 (Egger et al., 1999), and its test–retest reliability study was conducted in 2006 (Egger et al., 2006). The OÖÇ-PD includes items from the Diagnostic and Statistical Manual of Mental Disorders (DSM) applicable to young children, the DC: 0–5™ Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood, the Research Diagnostic Criteria–Preschool Age, as well as certain behaviors and symptoms not included in any diagnostic system but experienced by children and their caregivers. The interview also evaluates functional impairments arising from symptoms, family environment and relationships, family psychosocial problems, and life events, thereby addressing not only disorders or problematic areas but all domains contributing to the mental well-being of young children. Updated in accordance with evolving diagnostic systems since its development, the OÖÇ-PD has been used in numerous studies in the field of preschool child mental health (Dougherty et al., 2018; Pagliaccio et al., 2018).
The use of the OÖÇ-PD as a diagnostic tool in the field of preschool child mental health is anticipated to promote the development of effective prevention and early intervention programs. Furthermore, by establishing a shared language of assessment and diagnosis among evaluators, its use in community child mental health screenings is expected to contribute to shaping infant mental health programs in Türkiye.
CONTENT
The training includes the theoretical framework and practical applications of the Psychiatric Assessment of Preschool-Aged Children (Preschool Age Psychiatric Assessment – PAPA- OÖÇ-PD) diagnostic interview. Upon completion of the training, participants will be awarded a certificate enabling them to use this interview method in their clinical practice and research.
QUALIFICATION OF THE TRAINING
Infancy and early childhood, defined as the play age or preschool period, represent one of the most critical stages in mental health development. An increasing body of scientific evidence demonstrates that brain development during infancy and early childhood differs qualitatively and quantitatively from all other life stages, and that the brain—shaped by early life experiences during this period—affects an individual’s lifelong health, personality, behavior, and learning. Therefore, interventions during this stage are more effective and vital than those implemented later in life. Research on children with psychopathology also indicates that interventions provided before school entry may be more effective than later treatments and can yield long-term gains, underscoring the importance of this period. Considering both childhood and economic outcomes, early interventions are regarded as highly important and necessary—representing a gain for the child, a gain for the family, and a significant gain for society.
Children under the age of 6 have rates of mental disorders (14% to 20%) comparable to those of older children and adolescents. Young people and their families often report that mental health difficulties began during the preschool years. Studies in the literature indicate that between 16% and 26% of preschool children aged 2–5 without prior psychiatric referral meet criteria for “any psychiatric disorder.” With increasing awareness of the intergenerational transmission of major psychiatric disorders and evidence of temperamental and biological differences in young children at risk for these disorders, identifying the earliest manifestations of illness has become critically important for research, prevention, and treatment. Numerous studies have also demonstrated that mental symptoms and relational difficulties emerging during this period are associated with various social, emotional, and behavioral problems in childhood and are significant predictors of later psychopathology.
In conclusion, early diagnosis and intervention during infancy and early childhood are considered among the most effective preventive and protective strategies for reducing the burden of mental disorders in childhood. However, one of the greatest challenges in preschool mental health—despite its critical importance in mental health development—is accurately assessing children’s mental symptoms and reaching valid diagnoses. Given the inconsistencies and biases inherent in unstructured evaluations in the field of mental health, progress in developing standardized, structured diagnostic assessments has accelerated in recent years. Structured clinical interviews are suggested as a means to overcome assessment challenges (such as frequent changes in diagnosis over short intervals, different interviewers assigning different diagnoses to the same patient, and variability in the interpretation of diagnostic criteria by clinicians with different diagnostic approaches). These interviews differ from conventional clinical evaluations in both style and content. Ensuring that all evaluators follow the same interview structure and content increases the reliability of the diagnoses reached. Although structured interviews may take slightly longer than conventional interviews, accurate diagnoses achieved through structured methods enhance treatment effectiveness and ultimately represent a more efficient use of time.
The Psychiatric Assessment of Preschool-Aged Children (Preschool Age Psychiatric Assessment – PAPA- OÖÇ-PD), an interview developed for diagnosing psychiatric symptoms and disorders in children aged 2–7 years, was developed by Egger, Ascher, and Angold in 1999, and its test–retest reliability study was conducted in 2006. Updated in accordance with evolving diagnostic systems since its development, the OÖÇ-PD has been used in numerous studies in the field of preschool child mental health and is considered the gold standard method for diagnosing mental disorders in the preschool period.
The use of the OÖÇ-PD as a diagnostic tool in the field of preschool child mental health is anticipated to promote the development of effective prevention and early intervention programs.
Within the scope of a TÜBİTAK project (220S389) previously conducted by the Department of Child and Adolescent Psychiatry at Ankara University, training for this diagnostic interview was received from Duke University in the United States by the program developers. The training has been translated into Turkish and prepared for implementation in Türkiye.
