Introduction

The Ritvo Autism and Asperger Diagnostic Scale-Revised (RAADS-14) is a diagnostic tool specifically designed to assist in the identification of autism spectrum disorder (ASD) in adults. It is a shortened version of the original RAADS, offering a more concise assessment process while maintaining a focus on the core aspects of ASD. The RAADS-14 evaluates symptoms across four domains: language, social relatedness, sensory-motor, and circumscribed interests. By addressing these areas, the tool aims to capture the breadth of ASD characteristics, facilitating the diagnostic process for clinicians and researchers alike.

Developed through clinical research, the RAADS-14 is intended for use with adults who have a minimum verbal IQ of 80, ensuring that the questionnaire is accessible to a wide range of individuals seeking clarification regarding potential ASD traits. The scale comprises 14 items, each requiring the respondent to reflect on their behaviors, experiences, and preferences. Responses are quantified, allowing for a systematic assessment that supports the clinical judgment. This quantitative approach aids in distinguishing between ASD and other conditions that may present with overlapping symptoms, such as social anxiety disorder or attention deficit hyperactivity disorder (ADHD).

The RAADS-14's streamlined format is a significant aspect of its application in clinical and research settings. By reducing the number of items from the original scale, the RAADS-14 offers a quicker assessment tool without compromising the depth of insight into the individual's condition. This efficiency is particularly valuable in busy clinical environments or in large-scale research studies where time constraints are a consideration. Furthermore, the RAADS-14 promotes greater understanding and awareness of ASD in adults, a population for whom diagnosis can often be challenging. Early identification and diagnosis can lead to more targeted support and intervention, enhancing the quality of life for individuals with ASD. Through its targeted and efficient assessment, the RAADS-14 contributes to the broader efforts to improve diagnostic processes and outcomes for adults on the autism spectrum.

Scoring and result metrics

The result page reports a local screening score for this questionnaire. Use the score range, any subscale scores, and the interpretation band together rather than treating one number as a diagnosis.

Score range
0-42
Items scored

Result indicators
Total score / Interpretation band when available

Score interpretation bands

  • 0-13Lower range

    Scores in the 0-13 range are generally not indicative of an Autism Spectrum Disorder.

  • 14-42Elevated range

    Scores of 14 and above are considered indicative of an Autism Spectrum Disorder.

Interpretation bands summarize screening thresholds from the questionnaire source material. Higher scores usually indicate more of the measured concern unless the tool notes a different scoring rule.
