Survivors of childhood cancer are at risk for developing neurocognitive sequelae. Multiple meta-analyses demonstrate significant deficits in overall intellectual abilities, academic functioning and specific cognitive skills among survivors of childhood cancer treated with intrathecal chemotherapy only and/or cranial irradiation. Preventing neurocognitive deficits is therefore of great importance. Unfortunately, intervention studies for this group of survivors are scarce. The main aim of this randomized controlled trial is to determine the efficacy of Goal Management Training (GMT) as a group-based treatment program for 60 adult survivors of childhood leukemia, and non Hodgkins lymphoma, diagnosed between 1980 and 2017 at an age below 18, with attention and executive function deficits. The participants will be randomized to one treatment group (GMT), and one waitlist condition followed by one active control intervention, the "Brain health workshop" (BHW), which has a psycho-educative approach. The follow-up time from diagnosis will be ≥5 years and the age at survey 18-40 years. The study will expand the knowledge base on treatment factors important in improving cognitive function. Results from this study can be implemented in rehabilitation for the young adult survivors of childhood leukemia, and non Hodgkins lymphoma, which will be of importance for their future educational and work-related functioning.
Effect of the GMT/waitlist conditions will be assessed through self-reported and objective measures of neuropsychological function, quality of life and health measurements. To avoid extra training effects of neuropsychological testing on participants allocated to waitlist/BHW, assessment following BHW (approximately one-year post T1) will consist of self-report measures only. Patients in all groups will be reassessed within 14 days post intervention (T2), and at 6 months post intervention (T3).

The manual comprises an introduction to GMT for the survivors of ALL, and a detailed session structure incorporating cognitive and behavioral tasks. The GMT program involves teaching the participants about goals, attention slips and how to manage these, how to review and prioritize goals (e.g., Stop, Think, Organize, Plan), and how to keep goals in mind (e.g., using analogies such as the mental blackboard). Each session will follow the same general format; namely, facility-delivered presentations, flipchart discussions, group activities and homework.
BHW is a psycho-educative control condition, and is typically part of psycho-educative Acquired Brain Injury (ABI) rehabilitation programs, but adjusted for the ALL group of participants. The psycho-educative control condition BHW will be matched GMT for amount of training and therapist contact. Homework assignment and in-session tasks included readings, brain games, puzzles, and practical exercises such as logging sleep.

The Behavior Rating Inventory of Executive Function, Adult (BRIEF-A)
The BRIEF-A self-report questionnaire consists of 75 items on which the patient's symptoms are rated on a 3-point Likert scale. The questionnaire provides a Global Executive Composite (GEC) score (range 75-225) and two index scores: the Behavioral Regulation Index (BRI) (range 30-90) and the Metacognitive Index (MI) (range 40-120). Nine subscales are also provided: Inhibit (range 8-24), Shift (range 6-18), Emotional control (range 10-30), Self-monitor (range 6-18), Initiate (range 8-24), Working memory (range 8-24), Plan/organize (range 10-30), Task monitor (range 6-18) and Organization of materials (range 8-24). Higher scores indicate more executive difficulties. Raw scores are transformed into t scores (M=50, SD=10).
Time frame: 6 months
Conner's Continuous Performance Test (CPT-3)
The CPT 3 is a measure of inattention, impulsivity, sustained attention and vigilance. The test is computer based and lasts approximately 14 minutes. The participant is instructed to press the space bar/computer mouse when letters appear, but not when Xs appear on the screen. Higher scores reflect worse performance, and raw scores are converted to T-scores (M=50, SD=10). However, scores will be recoded so that higher scores equal better performance/lower scores equal worse performance.
Time frame: 6 months
The Color-Word Interference Test (CWI), from Delis Kaplan Executive Function System
The CWI is a measure of inhibition and cognitive flexibility. The test consists of four conditions; color naming (condition 1), word reading (condition 2), inhibition (condition 3) and inhibition switching (condition 4). Scores are computed for completion time (condition 1-4) and total errors (condition 3 and 4). Higher scores reflect better performance, and raw scores are converted to scaled scores (M=10, SD=3).
Time frame: 6 months
The Trail Making Test (TMT): from Delis Kaplan Executive Function System
The TMT from Delis Kaplan Executive Function System is a measure of flexibility/shifting. The primary measure is condition 4 where the participant is asked to shift between number and letter sequencing. The test also measures the basic abilities of visual scanning (condition 1), number- and letter sequencing combined with drawing a line (condition 2 and 3) and motor pace (Condition 5). Scores reflect completion time and raw scores are converted to scaled scores (M=10, SD=3). Higher scores reflect better performance.
Time frame: 6 months
California Verbal Learning Test (CVLT II)
The CVLT II a measure of verbal learning and memory. Participants are asked to recall words from list A, both with and without an interruption list B. There are three types of conditions; the participant is asked to freely recall items (free recall), to recall after a cue is presented (cued recall) and to recognize previously presented words (recognition condition). Both short and long delay is measured. Raw scores are converted to Z-scores (M=0, SD=1) and T-scores (M=50, SD=10). Higher scores reflect better performance, except for error measures. For T2 (14 days) follow up, CVLT II Alternative Form will be used.
Time frame: 6 months
Wisconsin Card Sorting Test (WCST-64)
The WCST-64 is a measure of abstract thinking and set-shifting/ mental flexibility. The participant is instructed to sort cards according to varying principles. A computer-based version will be employed. Raw scores are converted to T-scores (M=50, SD=10) and higher scores reflect better performance.
Time frame: 6 months
The Hotel Task
The Hotel Task is a measure of executive components: planning, organization, self-monitoring and cognitive flexibility. The participant is asked to try out as many as possible of five tasks within a relatively short (15 minutes) time period. Raw scores are computed. Higher scores reflect better performance, except for deviation of optimal time use. The test has been demonstrated to have high ecological validity and ability to detect frontal lobe dysfunction.
Time frame: 6 months
The Dysexecutive Questionnaire (DEX - self-report)
The DEX - self-report is a measure of everyday problems with executive function. The questionnaire consists of 20 items with a 5-point Likert scale where the respondent is asked to rate the frequency of cognitive difficulties from 0 (never) to 4 (very often). A higher total score reflects worse executive functioning.
Time frame: 6 months
Wechsler Adult Intelligent Scale-IV - Fourth Edition (WAIS-IV)
The subtests: Digit span, letter-number sequencing performance will be used as a measure of Verbal working memory/attention (Working memory index).
Time frame: 6 months
