Eight Sessions and a Ten-Week Wait
A 15-year-old Year 10 student is referred to the school guidance counsellor with a PHQ-A score of 18, sleep onset after 1 a.m., declining attendance (72% this term), and withdrawal from hockey. There is no psychosis, no current self-harm, and no substance use. The family whānau want to try rongoā Māori alongside talking therapy and are wary of medication. CAMHS has a 10-week waitlist. The counsellor has eight allocated sessions and has been trained in CBT, but a review of session recordings shows two core components (behavioural activation and cognitive restructuring) were delivered in only two of the first four sessions; instead sessions focused on rapport and sleep hygiene. The counsellor proposes extending to 16 sessions and adding a structured mood monitor. The school wants a risk assessment completed before any off-site referral.
1. Using formulation and measurement-based care, decide whether to extend to 16 sessions or change the approach, and justify your decision.

Extending to 16 sessions increases dose but does not fix the likely problem: the active ingredients are not being delivered. A PHQ-A of 18 with functional decline (72% attendance, withdrawal from hockey, delayed sleep) suggests moderate-to-severe depression and warrants a formulation that identifies maintaining cycles - for example, low mood leading to withdrawal, reduced activity and achievement, further low mood, and disrupted sleep. Measurement-based care should include re-administering the PHQ-A every two weeks, setting an explicit target such as a 50% reduction or PHQ-A below 10 by session 8, and tracking attendance and behavioural goals. If fidelity data show only two of four core components delivered, the first quality improvement is to deliver behavioural activation and cognitive work with adherence, not to add sessions. A fair test would be four well-delivered sessions with weekly monitoring. If there is no early response (for example, less than a 5-point PHQ-A change by session 6), escalate to CAMHS or reconsider modality. Extending a low-fidelity intervention risks drift, dependency, and delaying effective care, especially with a 10-week CAMHS wait that makes a bridging plan necessary.
2. How should the counsellor balance cultural responsiveness with fidelity to the CBT protocol?
Read the worked answer
Cultural responsiveness and fidelity are not opposites if the mechanisms are kept intact. Whānau involvement and rongoā can improve engagement, meaning-making, and adherence, which are plausible active ingredients rather than distractions. The counsellor should co-design the framing with the young person and whānau - for example, using whakapapa, mauri, and whānau goals to organise behavioural activation - while retaining the functional core: scheduling valued activity, monitoring mood and activity, testing unhelpful cognitions, and using homework. A fidelity checklist can be adapted at the level of language, metaphor, and delivery context without dropping the components. The counsellor should ask what rongoā involves, check for interactions or competing demands, and agree how both will be monitored. Culture should not become an excuse for non-delivery: if sessions remain rapport-only, the young person is not receiving an evidence-based dose. The ethical course is transparent shared decision-making, a time-limited trial, and outcome monitoring that includes the young person's own goals, not just the PHQ-A.
3. What risk and safety planning is required given the high PHQ-A score but no current self-harm?
Read the worked answer
The absence of current self-harm is not reassurance enough. A PHQ-A of 18, sleep disruption, social withdrawal, and school avoidance are risk-relevant, and risk should be assessed directly rather than inferred. The counsellor should ask about suicidal ideation, intent, plan, access to means, previous attempts, non-suicidal self-injury, substance use, and protective factors including whānau support and reasons for living. A collaborative safety plan should be documented with warning signs, coping strategies, people to contact, and emergency numbers, and shared with the young person and, with consent, whānau. The school protocol should specify who is informed, how confidentiality is explained, and follow-up within 48 hours if risk is elevated. Because the school wants a risk assessment before off-site referral, the counsellor should distinguish a school safety plan from a specialist assessment; if risk is active, the 10-week CAMHS wait is not acceptable and urgent pathways should be used. Documentation should record what was asked, what was disclosed, decisions made, and reasons.
