The Computerized Retraining and Functional Treatment - Group Intervention

A self-report questionnaire for cancer patients capturing subjective experiences of cognitive decline. The participants are asked to rate the items on a five-level scale ranging from 0="never" or "not at all" to 4="several times a day" or "very much;" higher scores represent better perceived cognitive function and QoL. Minimal clinically important difference (MCID) for the FACT-Cog was found to range from +4.7% to +7.2% for improvement (Liang et al., 2019), and -6.9 to -10.6 points for reduction.

A semi-structured interview used to assess the self-perception of clients' performance and satisfaction with performance in individual functional goals. The goals are quantified by rating importance, performance, and satisfaction on a 10-point Likert scale. A higher score indicates a greater outcome. A two-point difference between measurements taken at different time points is considered the Minimal Clinically Important Difference (MCID).

The PQRS is used in conjunction with the COPM, to compliment the client's perceived performance with actual performance or client's self-report performance of the client-selected goal. The researcher or clinician rates the performance on a scale of 1 (the skill is not done well) to 10 (the skill is performed very well). A two-point difference between measurements taken at different time points is considered the Minimal Clinically Important Difference (MCID).

Cognitive assessment will be conducted using the Effectivate online cognitive training platform, which includes four tasks assessing the following cognitive domains: (1) processing speed, (2) executive attention, (3) nonverbal visual memory and binding, and (4) declarative and working memory. Performance will be evaluated based on differences in mean response time and percentage of correct responses across tasks.

The tool measures quality of life and perceived health condition. Each of the five EQ-5D dimensions has five levels, generating a 5-digit code that represents the participant's health state (1=no problems up to 5=extreme problems). The EQ VAS provides a self-rated measure of overall health on a vertical scale ranging from 'the best' to 'the worst' health imaginable. The VAS can be used as a quantitative measure of health outcome.

The questionnaire iis used to measure hope for the goals set on COPM. . The GSHS contains 6 items divided equally into agency and pathways subscales. Respondents rate each item on a scale ranging from 1 (definitely false) to 8 (definitely true). An example agency item is, ''I energetically pursue this goal,'' and an example pathways item is, ''I can think of many ways to achieve this goal.'' Scores can range from 3 to 24 for the agency and pathways subscales and from 6 to 48 for total hope.

A self-reporting instrument developed to assess emotional distress across three domains19: Depression, Anxiety, and Stress. A four-point Likert-type response format is used for scoring. A higher score indicates a greater distress.

A self-report instrument designed to measure individuals' tendencies to be kind and understanding toward themselves during difficult times, rather than self-critical or judgmental. Each item is rated on a 5-point Likert scale, ranging from 1 ("almost never") to 5 ("almost always"). Higher total scores reflect greater levels of self-compassion.

The tool identifies and assess the qualities of cancer-related loneliness in adult cancer survivors who have completed treatment. Qualities that will be identified, their level of emotional distress it causes for the individual will be assessed. As loneliness is not a clinical condition for which specific diagnostic symptoms and cut-offs exist. For the study's purpose, we generated a score from 0 to 60, to indicate the severity of qualities' emotional distress level. A higher score indicates a severer emotional distress.

The questionnaire was developed for the purposes of the study and includes questions about the components of the intervention, delivery format and relationship with group leader and members. A five-point scale (1="to a very little extent" to 5="to a very large extent").
