Part 1 — Clinical Diagnostic Assessment

Cambridge Depersonalisation Scale (CDS)

Sierra & Berrios (2000). Rate the frequency and duration of each experience over the last 6 months.
Frequency: 0=Never · 1=Rarely · 2=Often · 3=Very often · 4=All the time  |  Duration when it occurs: 0=Not present · 1=Few seconds · 2=Few minutes · 3=Few hours · 4=About a day · 5=More than a day · 6=More than a week

Differential Screening

Clinical Exclusion Assessment

Before results can be confirmed, DSM-5 300.6 (APA, 2013) and ICD-11 6B66 (WHO, 2019) require the following conditions to be considered and where possible excluded. For each condition, indicate the clinical status based on available information.

Diagnostic Results

Scoring: frequency + duration per item (max per item = 10, max total = 290).
Clinical threshold ≥70 (sensitivity 75.5–76.3%, specificity 87.2–89.1%; Sierra & Berrios, 2000).
