Some cancer survivors experience post-treatment mental and/or physical health symptoms impacting quality of life, such as cognitive decline. There is limited access to evidence-based individualised interventions for cognitive concerns of cancer survivors.

This study aimed to assess the feasibility and acceptability of an individually delivered Responding to Cognitive Concerns − Individual (ReCogI) program, adapted from manualised cognitive behavioural group program Responding to Cognitive Concerns (ReCog), and to assess whether ReCogI influenced perceived cognitive function and health following cancer treatment.

A single-case experimental intervention design was used within a case series, with random allocation to a 3- or 4-week baseline period. Five cancer survivors completed ReCogI and questionnaires regarding program satisfaction, cognitive function, depression, anxiety, fatigue, and sleep.

Four of five participants showed statistically reliable individual improvement in at least one of two measures of self-reported cognitive functioning using the Reliable Change Index. However, neither cognitive measure was reliably higher during intervention than baseline when participant results were combined together to estimate between-case standardised mean difference. A participant satisfaction measure demonstrated high satisfaction with ReCogI ( M  = 4.6/5, SD  = 0.55).

ReCogI showed preliminary indications of feasibility and acceptability for assisting adult cancer survivors who report cognitive problems.
