Diagnosis and Culturally Adapted CBT in a Community Clinic

A community clinic in Birmingham serves a diverse population. It runs a 12-session group CBT programme for adults with moderate depression. Attendance is 70% overall but 45% among Somali-born attendees; clinicians notice that many describe their low mood through headaches and fatigue rather than sadness. A 16-year-old, Amina, is referred by her school for "low mood and poor concentration"; the school requests a diagnosis to grant extra time in examinations. Amina says her sleep is poor and she feels "heavy", but she does not use the word "depressed". Her mother prefers a religious explanation and is wary of medication. The clinic uses DSM-5 criteria and a validated symptom scale that has not been validated in Amina's first language.

Validity concerns whether the diagnosis captures the person's actual difficulties; reliability concerns consistency across clinicians and time. Amina's presentation (poor sleep, heaviness, poor concentration) overlaps with depression but also with anaemia, thyroid problems, or adjustment to school. The clinic uses DSM-5, which requires duration and impairment criteria; a school referral alone is not enough.

Cultural validity is central: in some cultural contexts distress is expressed somatically, and a clinician who counts only the word "depressed" may under-diagnose or mislabel. The symptom scale has not been validated in Amina's first language, so scores may not be equivalent; this threatens reliability and construct validity. Developmental validity matters too: irritability and withdrawal are common in adolescent depression, but thresholds and informants differ from adults. To improve reliability, use a trained interpreter, a structured interview, and collateral information from school and family with consent. To improve validity, explore the meaning of "heavy" and the family's explanatory model, and rule out medical causes. No diagnosis should be made from a single scale score.

2. Evaluate the clinic's plan to culturally adapt the CBT group. What evidence and ethical issues matter?

Cultural adaptation is reasonable, but it must be evidence-based and not a slogan. The low attendance among Somali-born attendees suggests a mismatch in language, group format or illness model. Evidence supports culturally adapted CBT when adaptations are both surface-level (language, images) and deep-level (explanatory model, family involvement), but adaptation must retain the active ingredients: behavioural activation, cognitive restructuring and exposure where relevant.

Ethically, the clinic must not simply "fix" patients to fit the programme; it should ask what the community wants. It should involve community advisers, use professional interpreters, and consider separate groups or a hybrid format. Staff need training in cultural humility. Evaluate with attendance, symptom measures validated in the relevant language, and qualitative feedback. A risk is that adaptation becomes stereotyping; not every Somali patient wants a religious framing. The mother's preference for a religious explanation should be explored, not dismissed, and collaboration with a faith leader may improve engagement. Informed consent and confidentiality must be clear, especially in a small community.

3. Advise on the school's request for a diagnosis. What ethical and clinical considerations apply, and what alternatives exist?

Read the worked answer

The school's request is understandable, but a diagnosis should not be produced primarily to obtain exam access arrangements. Ethically, the clinic must act in Amina's best interests and avoid a label that may stigmatise her or close down other explanations. Clinically, the assessment should be thorough: interview Amina alone and with her mother, screen for medical causes and self-harm, and consider a formulation rather than a diagnosis if criteria are not met.

The school can be given a functional statement, for example: "Amina is experiencing significant sleep disturbance and concentration difficulties; extra time and a quiet room are recommended" without a DSM label. Amina is 16, so her assent matters; her mother should be involved, but Amina's confidentiality should be explained. If a diagnosis is made, it should be communicated with care, with psychoeducation and a plan, and the school should receive only the minimum necessary information. The clinic should monitor whether the label changes teachers' expectations, which is a known stereotype-threat risk.
