What do Patients Remember 24 Hours and One Week After a Psychiatric Consultation, and Does Recall Influence Adherence? A Narrative Review

Objective: To synthesise evidence on what patients retain 24 hours and about one week after a psychiatric consultation, the determinants of that retention, whether recall influences treatment adherence, and which interventions improve recall and adherence.Methods: A narrative review, structured according to SANRA criteria, of systematic reviews, meta-analyses, randomised trials and observational studies, prioritising studies that verified recall against recorded consultation content. Evidence was organised around a causal model running from communication through encoding, retention, comprehension, beliefs and intention to adherence.Results: Across medical settings, 40–80% of consultation information is forgotten almost immediately and about half of what is recalled is inaccurate. At one week, only 49% of decisions and recommendations are freely and accurately recalled (85% with prompting), with a steep educational gradient (38% vs 65%). Direct data at 24 hours, and psychiatry-specific data at either interval, are scarce. Disorder-related deficits in effortful encoding (depression) and free recall (schizophrenia; d = 1.21 vs 0.64 for recognition) compound ordinary forgetting. Communication quality predicts adherence (19% higher risk of non-adherence with poor communicators; 1.62-fold higher odds after training; OR 5.82 for conversational repair in schizophrenia), but knowledge correlates only weakly with adherence and is outweighed by necessity–concern beliefs, insight, depression and alliance. Personalised recordings, written material, explicit structuring and teach-back reliably improve recall but improve adherence inconsistently.Conclusion: Recall is a necessary but insufficient condition for adherence in psychiatry; its link to behaviour is heavily mediated by beliefs and confounded by mood.Practice implications: Psychiatrists should engineer recall deliberately—limit and prioritise content, structure it explicitly, provide personalised written or recorded summaries and verify understanding with teach-back—while simultaneously addressing medication beliefs, mood and the therapeutic alliance.
